+
+Functionality
+
+This plugin is based on a discussion in comp.editors (see the thread at
+http://groups.google.com/group/comp.editors/browse_frm/thread/0f562d97f80dde13)
+
+Narrowing means focussing on a region and making the rest inaccessible. You
+simply select the region, call |:NarrowRegion| and the selected part will open
+in a new scratch buffer. The rest of the file will be protected, so you won't
+accidentally modify that buffer. In the new buffer, you can do a global
+replace, search or anything else to modify that part. When you are finished,
+simply write that buffer (e.g. by |:w|) and your modifications will be put in
+the original buffer making it accessible again. Use |:q!| or |:bw!| to abort
+your changes and return back to the original window.
+
+NrrwRgn allows you to either select a line based selection using an Ex-command
+or you can simply use any visual selected region and press your preferred key
+combination to open that selection in a new buffer.
+
+This plugin defines the following commands:
+
+                                                        *:NarrowRegion* *:NR*
+:[range]NR[!]
+:[range]NarrowRegion[!]     When [range] is omitted, select only the current
+                            line, else use the lines in the range given and
+                            open it in a new Scratch Window.
+                            If the current line is selected and is on a folded
+                            region, select the whole folded text.
+                            Whenever you are finished modifying that region
+                            simply write the buffer.
+                            If ! is given, open the narrowed buffer not in a
+                            split buffer but in the current window.
+
+                                                        *:NarrowWindow* *:NW*
+:NW[!]
+:NarrowWindow[!]            Select only the range that is visible the current
+                            window and open it in a new Scratch Window.
+                            Whenever you are finished modifying that region
+                            simply write the buffer.
+                            If ! is given, open the narrowed buffer not in a
+                            split buffer but in the current window (works best
+                            with 'hidden' set).
+
+                                                                *:WidenRegion*
+:WidenRegion[!]             This command is only available in the narrowed
+                            scratch window. If the buffer has been modified,
+                            the contents will be put back on the original
+                            buffer. If ! is specified, the window will be
+                            closed, otherwise it will remain open.
+
+                                                                        *:NRV*
+:NRV[!]                     Opened the narrowed window for the region that was
+                            last selected in visual mode
+                            If ! is given, open the narrowed buffer not in a
+                            split buffer but in the current window (works best
+                            with 'hidden' set).
+
+                                                                        *:NUD*
+
+:NUD                        When viewing unified diffs, this command opens
+                            the current chunk in 2 Narrowed Windows in
+                            |diff-mode| The current chunk is determined as the
+                            one, that the cursor is at. This command does not
+                            make sense if editing a different file format (or
+                            even different diff format)
+
+                                                                  *:NRPrepare*
+:[range]NRPrepare[!]
+:[range]NRP[!]              You can use this command, to mark several lines
+                            that will later be put into a Narrowed Window
+                            using |:NRM|.
+                            If the ! is used, all earlier selected lines will
+                            be cleared first.
+
+                                                                  *:NRMulti*
+:NRMulti
+:NRM[!]                     This command takes all lines, that have been
+                            marked by |:NRP| and puts them together in a new
+                            narrowed buffer.
+                            When you write your changes back, all separate
+                            lines will be put back at their origin.
+                            This command also clears the list of marked lines,
+                            that was created with |NRP|.
+                            See also |NR-multi-example|.
+                            If ! is given, open the narrowed buffer not in a
+                            split buffer but in the current window (works best
+                            with 'hidden' set).
+
+                                                    *:NRSyncOnWrite* *:NRS*
+:NRSyncOnWrite
+:NRS                        Enable synching the buffer content back to the
+                            original buffer when writing.
+                            (this is the default).
+
+                                                    *:NRNoSyncOnWrite* *:NRN*
+:NRNoSyncOnWrite
+:NRN                        Disable synching the buffer content back to the
+                            original buffer when writing. When set, the
+                            narrowed buffer behaves like an ordinary buffer
+                            that you can write in the filesystem.
+                            (this is the default).
+                            Note: You can still use |:WidenRegion| to write
+                            the changes back to the original buffer.
+
+                                                                    *:NRL*
+
+:NRL[!]                     Reselect the last selected region again and open
+                            in a narrowed window.
+                            If ! is given, open the narrowed buffer not in a
+                            split buffer but in the current window (works best
+                            with 'hidden' set).
+
+
+2.1 NrrwRgn HowTo                                                *NR-HowTo*
+-----------------
+
+Use the commands provided above to select a certain region to narrow. You can
+also start visual mode and have the selected region being narrowed. In this
+mode, NarrowRegion allows you to block select |CTRL-V| , character select |v|
+or linewise select |V| a region. Then press <Leader>nr where <Leader> by
+default is set to '\', unless you have set it to something different (see
+|<Leader>| for information how to change this) and the selected range will
+open in a new scratch buffer. This key combination only works in |Visual-mode|
+If instead of <Leader>nr you use <Leader>Nr in visual mode, the selection will
+be opened in the current window, replacing the original buffer.
+
+(Alternatively, you can use the normal mode mapping <Leader>nr and the region
+over which you move will be opened in a new Narrowed window).
+
+When finished, simply write that Narrowed Region window, from which you want
+to take the modifications in your original file.
+
+It is possible, to recursively open a Narrowed Window on top of an already
+narrowed window. This sounds a little bit silly, but this makes it possible,
+to have several narrowed windows, which you can use for several different
+things, e.g. If you have 2 different buffers opened and you want to diff a
+certain region of each of those 2 buffers, simply open a Narrowed Window for
+each buffer, and execute |:diffthis| in each narrowed window.
+
+You can then interactively merge those 2 windows. And when you are finished,
+simply write the narrowed window and the changes will be taken back into the
+original buffer.
+
+When viewing unified diffs, you can use the provided |:NUD| command to open 2
+Narrowed Windows side by side viewing the current chunk in |diff-mode|. Those
+2 Narrowed windows will be marked 'modified', since there was some post
+processing involved when opening the narrowed windows. Be careful, when
+quitting the windows, not to write unwanted changes into your patch file! In
+the window that contains the unified buffer, you can move to a different
+chunk, run |:NUD| and the 2 Narrowed Windows in diff mode will update.
+
+2.2 NrrwRgn Multi                                    *NR-multi-example*
+-----------------
+
+Using the commands |:NRP| and |:NRM| allows to select a range of lines, that
+will be put into a narrowed buffer together. This might sound confusing, but
+this allows to apply a filter before making changes. For example before
+editing your config file, you decide to strip all comments for making big
+changes but when you write your changes back, these comments will stay in your
+file. You would do it like this: >
+    :v/^#/NRP
+    :NRMulti
+<
+Now a Narrowed Window will open, that contains only the configuration lines.
+Each block of independent region will be separated by a string like
+
+# Start NarrowRegion1
+.....
+# End NarrowRegion1
+
+This is needed, so the plugin later knows, which region belongs where in the
+original place. Blocks you don't want to change, you can safely delete, they
+won't be written back into your original file. But other than that, you
+shouldn't change those separating lines.
+
+When you are finished, simply write your changes back.
+
+==============================================================================
+
+2.3 NrrwRgn Configuration                                    *NrrwRgn-config*
+-------------------------
+
+NarrowRegion can be customized by setting some global variables. If you'd
+like to open the narrowed window as a vertical split buffer, simply set the
+variable g:nrrw_rgn_vert to 1 in your |.vimrc| >
+
+    let g:nrrw_rgn_vert = 1
+<
+(default: 0)
+------------------------------------------------------------------------------
+
+If you'd like to specify a certain width/height for you scratch buffer, then
+set the variable g:nrrw_rgn_wdth in your |.vimrc| . This variable defines the
+height or the nr of columns, if you have also set g:nrrw_rgn_vert. >
+
+    let g:nrrw_rgn_wdth = 30
+<
+(default: 20)
+
+Note: if the newly created narrowed window is smaller than this, it will be
+resized to fit (plus an additional padding that can be specified using the
+g:nrrw_rgn_pad variable (default: 0), to not leave unwanted space around (not
+for single narrowed windows, e.g. when the '!' attribute was used).
+
+------------------------------------------------------------------------------
+
+Resizing the narrowed window can happen either by some absolute values or by a
+relative percentage. The variable g:nrrw_rgn_resize_window determines what
+kind of resize will occur. If it is set to "absolute", the resizing will be
+done by absolute lines or columns (depending on whether a horizontal or
+vertical split has been done). If it is set to "relative" the window will be
+resized by a percentage.  Set it like this in your |.vimrc| >
+
+    let g:nrrw_rgn_resize_window = 'absolute'
+<
+(default: absolute)
+
+The percentages for increasing the window size can further be specified by
+seting the following variables:
+
+default:
+g:nrrw_rgn_rel_min: 10 (50 for vertical splits)
+g:nrrw_rgn_rel_max: 80
+
+------------------------------------------------------------------------------
+
+It is possible to specify an increment value, by which the narrowed window can
+be increased. This is allows to easily toggle between the normal narrowed
+window size and an even increased size (think of zooming). 
+
+You can either specify a relative or absolute zooming value. An absolute
+resize will happen, if the variable g:nrrw_rgn_resize_window is set to
+"absolute" or it is unset (see above).
+
+If absolute resizing should happen you have to either specify columns, if the
+Narrowed window is a vertical split window or lines, if a horizontal split has
+been done.
+
+Example, to increase the narrowed window by 30 lines or columns if
+(g:nrrw_rgn_vert is also set [see above]), set in your |.vimrc| >
+
+    let g:nrrw_rgn_incr = 30
+<
+(default: 10, if g:nrrw_rgn_resize_window is "absolute")
+
+Note: When using the '!' attribute for narrowing (e.g. the selection will be
+opened in a new window that takes the complete screen size), no resizeing will
+happen
+------------------------------------------------------------------------------
+
+If you'd like to change the key combination that toggles incrementing the
+Narrowed Window size, you can put this in your |.vimrc| >
+
+   nmap <F3> <Plug>NrrwrgnWinIncr
+<
+(default: <Leader><Space>)
+
+This will let you use the <F3> key to toggle the window size of the Narrowed
+Window. Note: This mapping is only in the narrowed window active.
+
+The amount of how much to increase can be further refined by setting the
+g:nrrw_rgn_incr for an absolute increase of by setting the variables
+g:nrrw_rgn_rel_min and g:nrrw_rgn_rel_max
+
+Whether an absolute or relative increase will be performed, is determined by
+the g:nrrw_rgn_resize_window variable (see above).
+------------------------------------------------------------------------------
+
+By default, NarrowRegion highlights the region that has been selected
+using the WildMenu highlighting (see |hl-WildMenu|). If you'd like to use a
+different highlighting, set the variable g:nrrw_rgn_hl to your preferred
+highlighting Group. For example to have the region highlighted like a search
+result, you could put that in your |.vimrc| >
+
+    let g:nrrw_rgn_hl = 'Search'
+<
+(default: WildMenu)
+
+If you want to turn off the highlighting (because this can be distracting), you
+can set the global variable g:nrrw_rgn_nohl to 1 in your |.vimrc| >
+
+    let g:nrrw_rgn_nohl = 1
+<
+(default: 0)
+------------------------------------------------------------------------------
+
+If you'd like to change the key combination that starts the Narrowed Window
+for your selected range, you could put this in your |.vimrc| >
+
+   xmap <F3> <Plug>NrrwrgnDo
+<
+This will let <F3> open the Narrow-Window, but only if you have pressed it in
+Visual Mode. It doesn't really make sense to map this combination to any other
+mode, unless you want it to Narrow your last visually selected range.
+
+(default: <Leader>nr)
+------------------------------------------------------------------------------
+
+If you'd like to specify the options that you want to have set for the
+narrowed window, you can set the g:nrrw_custom_options setting, in your
+|.vimrc| e.g. >
+
+   let g:nrrw_custom_options={}
+   let g:nrrw_custom_options['filetype'] = 'python'
+>
+This will only apply those options to the narrowed buffer. You need to take
+care that all options you need will apply.
+
+------------------------------------------------------------------------------
+
+If you don't like that your narrowed window opens above the current window,
+define the g:nrrw_topbot_leftright variable to your taste, e.g. >
+
+  let g:nrrw_topbot_leftright = 'botright'
+<
+Now, all narrowed windows will appear below the original window. If not
+specified, the narrowed window will appear above/left of the original window.
+
+(default: topleft)
+------------------------------------------------------------------------------
+
+If you want to use several independent narrowed regions of the same buffer
+that you want to write at the same time, protecting the original buffer is not
+really useful. Therefore, set the g:nrrw_rgn_protect variable, e.g. in your
+|.vimrc| >
+
+   let g:nrrw_rgn_protect = 'n'
+<
+This can be useful if you diff different regions of the same file, and want
+to be able to put back the changes at different positions. Please note that
+you should take care not to change any part that will later be influenced
+when writing the narrowed region back.
+
+Note: Don't use overlapping regions! Your changes will probably not be put
+back correctly and there is no guard against losing data accidentally. NrrwRgn
+tries hard to adjust the highlighting and regions as you write your changes
+back into the original buffer, but it can't guarantee that this will work and
+might fail silently. Therefore, this feature is experimental!
+
+(default: y)
+------------------------------------------------------------------------------
+
+If you are using the |:NRMulti| command and want to have the original window
+update to the position of where the cursor is in the narrowed window, you can
+set the variable g:nrrw_rgn_update_orig_win, e.g. in your |.vimrc| >
+
+   let g:nrrw_rgn_update_orig_win = 1
+<
+Now the cursor in the original window will always update when the position
+changes in the narrowed window (using a |CursorMoved| autocommand).
+Note: that this might slow down scrolling and cursor movement a bit.
+
+(default: 0)
+------------------------------------------------------------------------------
+
+By default, NarrowRegion plugin defines the two mappings <Leader>nr in visual
+mode and normal mode and <Leader>Nr only in visual mode. If you have your own
+mappings defined, than NarrowRegion will complain about the key already being
+defined. Chances are, this will be quite annoying to you, so you can disable
+mappings those keys by defining the following variables in your |.vimr| >
+
+  :let g:nrrw_rgn_nomap_nr = 1
+  :let g:nrrw_rgn_nomap_Nr = 1
+
+(default: 0)
+----------------------------------------------------------------------------
+                                                 *NrrwRgn-hook*  *NR-hooks*
+
+NarrowRegion can execute certain commands, when creating the narrowed window
+and when closing the narrowed window. For this, you can set 2 buffer-local
+variables that specify what commands to execute, which will hook into the
+execution of the Narrow Region plugin.
+
+For example, suppose you have a file, containing columns separated data (CSV
+format) which you want to modify and you also have the CSV filetype plugin
+(http://www.vim.org/scripts/script.php?script_id=2830) installed and you want
+to modify the CSV data which should be visually arranged like a table in the
+narrowed window.
+
+Therefore you want the command |:ArrangeColumn| to be executed in the new
+narrowed window upon entering it, and when writing the changes back, you want
+the command |:UnArrangeColumn| to be executed just before putting the
+changes back. So you set those two variables in your original buffer: >
+
+    let b:nrrw_aucmd_create = "set ft=csv|%ArrangeCol"
+    let b:nrrw_aucmd_close  = "%UnArrangeColumn"
+<
+This will execute the commands in the narrowed window: >
+
+    :set ft=csv
+    :%ArrangeCol
+
+and before writing the changes back, it'll execute: >
+
+    :%UnArrangeCol
+
+Note: These hooks are executed in the narrowed window (i.e. after creating the
+narrowed window and its content and before writing the changes back to the
+original buffer).
+
+A third hook 'b:nrrw_aucmd_written' is provided, when the data is written back
+in the original window. This allows to execute scripts, whenever the data is
+written back in the original window. For example, consider you want to write
+the original buffer whenever the narrowed window is written back to the
+original window. You can therefore set: >
+    
+    :let b:nrrw_aucmd_written = ':update'
+<
+This will write the original buffer, whenever it was modified after writing
+the changes from the narrowed window back.
+
+2.4 NrrwRgn functions                                    *NrrwRgn-func*
+---------------------
+The NrrwRgn plugin defines a public function in its namespace that can be used
+to query its status.
+                                                        *nrrwrgn#NrrwRgnStatus()*
+nrrwrgn#NrrwRgnStatus()
+    Returns a dict with the following keys:
+        'shortname':    The displayed buffer name
+        'fullname':     The complete buffer name of the original buffer
+        'multi':        1 if it is a multi narrowed window (|:NRMulti|),
+                        0 otherwise.
+        'startl':       List of start lines for a multi narrowed window
+                        (only present, if 'multi' is 1)
+        'endl':         List of end lines for a multi narrowed window
+                        (only present, if 'multi' is 1)
+        'start':        Start position (only present if 'multi' is 0)
+        'end':          End position (only present if 'multi' is 0)
+        'visual':       Visual Mode, if it the narrowed window was started
+                        from a visual selected region (empty otherwise).
+        'enabled':      Whether syncing the buffer is enabled (|:NRS|)
+                            
+    If not executed in a narrowed window, returns an empty dict.

+3. NrrwRgn Tips                                           *NrrwRgn-tips*
+
+To have the filetype in the narrowed window set, you can use this function: >
+
+  command! -nargs=* -bang -range -complete=filetype NN
+              \ :<line1>,<line2> call nrrwrgn#NrrwRgn('',<q-bang>)
+              \ | set filetype=<args>
+<
+This lets you select a region, call :NN sql and the selected region will get
+the sql filetype set.

+# NrrwRgn plugin [![Say Thanks!](https://img.shields.io/badge/Say%20Thanks-!-1EAEDB.svg)](https://saythanks.io/to/cb%40256bit.org)
+
+> A Vim plugin for focussing on a selected region
+
+This plugin is inspired by the [Narrowing feature of Emacs](http://www.emacswiki.org/emacs/Narrowing) and means to focus on a selected region while making the rest inaccessible. You simply select the region, call `:NR` and the selected part will open in a new split window while the rest of the buffer will be protected. Once you are finished, simply write the narrowed window (`:w`) and all the changes will be moved back to the original buffer.
+
+See also the following screencast, that shows several features available:
+![screencast of the plugin](screencast.gif "Screencast")
+
+## Installation
+
+Use the plugin manager of your choice. Or download the [stable][] version of the plugin, edit it with Vim (`vim NrrwRgn-XXX.vmb`) and simply source it (`:so %`). Restart and take a look at the help (`:h NrrwRgn.txt`)
+
+[stable]: http://www.vim.org/scripts/script.php?script_id=3075
+
+## Usage
+
+Once installed, take a look at the help at `:h NarrowRegion`.
+
+Here is a short overview of the functionality provided by the plugin:
+
+### Ex commands:
+
+    :NR  - Open the selected region in a new narrowed window
+    :NW  - Open the current visual window in a new narrowed window
+    :WR  - (In the narrowed window) write the changes back to the original buffer.
+    :NRV - Open the narrowed window for the region that was last visually selected.
+    :NUD - (In a unified diff) open the selected diff in 2 Narrowed windows
+    :NRP - Mark a region for a Multi narrowed window
+    :NRM - Create a new Multi narrowed window (after :NRP) - experimental!
+    :NRS - Enable Syncing the buffer content back (default on)
+    :NRN - Disable Syncing the buffer content back
+    :NRL - Reselect the last selected region and open it again in a narrowed window
+
+You can append `!` to most commands to open the narrowed part in the current window instead of a new window. In the case of `:WR`, appending `!` closes the narrowed window in addition to writing to the original buffer.
+
+### Visual mode commands:
+
+    <Leader>nr		 - Open the current visual selection in a new narrowed window
+

+
+Functionality
+
+This plugin is based on a discussion in comp.editors (see the thread at
+http://groups.google.com/group/comp.editors/browse_frm/thread/0f562d97f80dde13)
+
+Narrowing means focussing on a region and making the rest inaccessible. You
+simply select the region, call |:NarrowRegion| and the selected part will open
+in a new scratch buffer. The rest of the file will be protected, so you won't
+accidentally modify that buffer. In the new buffer, you can do a global
+replace, search or anything else to modify that part. When you are finished,
+simply write that buffer (e.g. by |:w|) and your modifications will be put in
+the original buffer making it accessible again. Use |:q!| or |:bw!| to abort
+your changes and return back to the original window.
+
+NrrwRgn allows you to either select a line based selection using an Ex-command
+or you can simply use any visual selected region and press your preferred key
+combination to open that selection in a new buffer.
+
+This plugin defines the following commands:
+
+                                                        *:NarrowRegion* *:NR*
+:[range]NR[!]
+:[range]NarrowRegion[!]     When [range] is omitted, select only the current
+                            line, else use the lines in the range given and
+                            open it in a new Scratch Window.
+                            If the current line is selected and is on a folded
+                            region, select the whole folded text.
+                            Whenever you are finished modifying that region
+                            simply write the buffer.
+                            If ! is given, open the narrowed buffer not in a
+                            split buffer but in the current window. However
+                            when 'hidden' is not set, will open a new split
+                            window. 
+
+                                                        *:NarrowWindow* *:NW*
+:NW[!]
+:NarrowWindow[!]            Select only the range that is visible the current
+                            window and open it in a new Scratch Window.
+                            Whenever you are finished modifying that region
+                            simply write the buffer.
+                            If ! is given, open the narrowed buffer not in a
+                            split buffer but in the current window (works best
+                            with 'hidden' set).
+
+                                                         *:WidenRegion* *:WR*
+:WR[!]
+:WidenRegion[!]             This command is only available in the narrowed
+                            scratch window. If the buffer has been modified,
+                            the contents will be put back on the original
+                            buffer. If ! is specified, the window will be
+                            closed, otherwise it will remain open.
+
+                                                                        *:NRV*
+:NRV[!]                     Opened the narrowed window for the region that was
+                            last selected in visual mode
+                            If ! is given, open the narrowed buffer not in a
+                            split buffer but in the current window (works best
+                            with 'hidden' set).
+
+                                                                        *:NUD*
+
+:NUD                        When viewing unified diffs, this command opens
+                            the current chunk in 2 Narrowed Windows in
+                            |diff-mode| The current chunk is determined as the
+                            one, that the cursor is at.
+                            For filetypes other than diffs, it will try to
+                            create a diff mode for a merge conflict.
+
+                                                                  *:NRPrepare*
+:[range]NRPrepare[!]
+:[range]NRP[!]              You can use this command, to mark several lines
+                            that will later be put into a Narrowed Window
+                            using |:NRM|.
+                            Using '!' clears the selection and does not add
+                            any lines.
+                            Use |:NRUnprepare| to remove a line again.
+
+                                                                  *:NRUnprepare*
+:[range]NRUnprepare[!]
+                            This command will remove the current line and
+                            remove it from the lines marked for use with |:NRM|.
+                            If the current line was not previously selected
+                            for a multi narrowed window, it is ignored.
+
+                                                                  *:NRMulti*
+:NRMulti
+:NRM[!]                     This command takes all lines, that have been
+                            marked by |:NRP| and puts them together in a new
+                            narrowed buffer.
+                            When you write your changes back, all separate
+                            lines will be put back at their origin.
+                            This command also clears the list of marked lines,
+                            that was created with |NRP|.
+                            See also |NR-multi-example|.
+                            If ! is given, open the narrowed buffer not in a
+                            split buffer but in the current window (works best
+                            with 'hidden' set).
+
+                                                    *:NRSyncOnWrite* *:NRS*
+:NRSyncOnWrite
+:NRS                        Enable synching the buffer content back to the
+                            original buffer when writing.
+                            (this is the default).
+
+                                                    *:NRNoSyncOnWrite* *:NRN*
+:NRNoSyncOnWrite
+:NRN                        Disable synching the buffer content back to the
+                            original buffer when writing. When set, the
+                            narrowed buffer behaves like an ordinary buffer
+                            that you can write in the filesystem.               
+                            Note: You can still use |:WidenRegion| to write
+                            the changes back to the original buffer.
+
+                                                                    *:NRL*
+
+:NRL[!]                     Reselect the last selected region again and open
+                            in a narrowed window.
+                            If ! is given, open the narrowed buffer not in a
+                            split buffer but in the current window (works best
+                            with 'hidden' set).
+
+
+2.1 NrrwRgn HowTo                                                *NR-HowTo*
+-----------------
+
+Use the commands provided above to select a certain region to narrow. You can
+also start visual mode and have the selected region being narrowed. In this
+mode, NarrowRegion allows you to block select |CTRL-V| , character select |v|
+or linewise select |V| a region. Then press <Leader>nr where <Leader> by
+default is set to '\', unless you have set it to something different (see
+|<Leader>| for information how to change this) and the selected range will
+open in a new scratch buffer. This key combination only works in |Visual-mode|
+If instead of <Leader>nr you use <Leader>Nr in visual mode, the selection will
+be opened in the current window, replacing the original buffer.
+
+(Alternatively, you can use the normal mode mapping <Leader>nr and the region
+over which you move will be opened in a new Narrowed window).
+
+When finished, simply write that Narrowed Region window, from which you want
+to take the modifications in your original file.
+
+It is possible, to recursively open a Narrowed Window on top of an already
+narrowed window. This sounds a little bit silly, but this makes it possible,
+to have several narrowed windows, which you can use for several different
+things, e.g. If you have 2 different buffers opened and you want to diff a
+certain region of each of those 2 buffers, simply open a Narrowed Window for
+each buffer, and execute |:diffthis| in each narrowed window.
+
+You can then interactively merge those 2 windows. And when you are finished,
+simply write the narrowed window and the changes will be taken back into the
+original buffer.
+
+When viewing unified diffs, you can use the provided |:NUD| command to open 2
+Narrowed Windows side by side viewing the current chunk in |diff-mode|. Those
+2 Narrowed windows will be marked 'modified', since there was some post
+processing involved when opening the narrowed windows. Be careful, when
+quitting the windows, not to write unwanted changes into your patch file! In
+the window that contains the unified buffer, you can move to a different
+chunk, run |:NUD| and the 2 Narrowed Windows in diff mode will update.
+
+2.2 NrrwRgn Multi                                    *NR-multi-example*
+-----------------
+
+Using the commands |:NRP| and |:NRM| allows to select a range of lines, that
+will be put into a narrowed buffer together. This might sound confusing, but
+this allows to apply a filter before making changes. For example before
+editing your config file, you decide to strip all comments for making big
+changes but when you write your changes back, these comments will stay in your
+file. You would do it like this: >
+    :v/^#/NRP
+    :NRMulti
+<
+Now a Narrowed Window will open, that contains only the configuration lines.
+Each block of independent region will be separated by a string like
+
+# Start NarrowRegion1
+.....
+# End NarrowRegion1
+
+This is needed, so the plugin later knows, which region belongs where in the
+original place. Blocks you don't want to change, you can safely delete, they
+won't be written back into your original file. But other than that, you
+shouldn't change those separating lines.
+
+When you are finished, simply write your changes back.
+
+==============================================================================
+
+2.3 NrrwRgn Configuration                                    *NrrwRgn-config*
+-------------------------
+
+NarrowRegion can be customized by setting some global variables. If you'd
+like to open the narrowed window as a vertical split buffer, simply set the
+variable *g:nrrw_rgn_vert* to 1 in your |.vimrc| >
+
+    let g:nrrw_rgn_vert = 1
+<
+(default: 0)
+------------------------------------------------------------------------------
+
+If you'd like to specify a certain width/height for you scratch buffer, then
+set the variable *g:nrrw_rgn_wdth* in your |.vimrc| . This variable defines the
+height or the nr of columns, if you have also set g:nrrw_rgn_vert. >
+
+    let g:nrrw_rgn_wdth = 30
+<
+(default: 20)
+
+Note: if the newly created narrowed window is smaller than this, it will be
+resized to fit (plus an additional padding that can be specified using the
+g:nrrw_rgn_pad variable (default: 0), to not leave unwanted space around (not
+for single narrowed windows, e.g. when the '!' attribute was used).
+
+------------------------------------------------------------------------------
+
+Resizing the narrowed window can happen either by some absolute values or by a
+relative percentage. The variable *g:nrrw_rgn_resize_window* determines what
+kind of resize will occur. If it is set to "absolute", the resizing will be
+done by absolute lines or columns (depending on whether a horizontal or
+vertical split has been done). If it is set to "relative" the window will be
+resized by a percentage.  Set it like this in your |.vimrc| >
+
+    let g:nrrw_rgn_resize_window = 'absolute'
+<
+(default: absolute)
+
+The percentages for increasing the window size can further be specified by
+seting the following variables:
+
+default:
+g:nrrw_rgn_rel_min: 10 (50 for vertical splits)
+g:nrrw_rgn_rel_max: 80
+
+------------------------------------------------------------------------------
+
+It is possible to specify an increment value, by which the narrowed window can
+be increased. This is allows to easily toggle between the normal narrowed
+window size and an even increased size (think of zooming). 
+
+You can either specify a relative or absolute zooming value. An absolute
+resize will happen, if the variable |g:nrrw_rgn_resize_window| is set to
+"absolute" or it is unset (see above).
+
+If absolute resizing should happen you have to either specify columns, if the
+Narrowed window is a vertical split window or lines, if a horizontal split has
+been done.
+
+Example, to increase the narrowed window by 30 lines or columns if
+(g:nrrw_rgn_vert is also set [see above]), set in your |.vimrc| >
+
+    let g:nrrw_rgn_incr = 30
+<
+(default: 10, if |g:nrrw_rgn_resize_window| is "absolute")
+
+Note: When using the '!' attribute for narrowing (e.g. the selection will be
+opened in a new window that takes the complete screen size), no resizeing will
+happen
+------------------------------------------------------------------------------
+
+If you'd like to change the key combination that toggles incrementing the
+Narrowed Window size, map *<Plug>NrrwrgnWinIncr* by putting this in your |.vimrc| >
+
+   nmap <F3> <Plug>NrrwrgnWinIncr
+<
+(default: <Leader><Space>)
+
+This will let you use the <F3> key to toggle the window size of the Narrowed
+Window. Note: This mapping is only in the narrowed window active.
+
+The amount of how much to increase can be further refined by setting the
+*g:nrrw_rgn_incr* for an absolute increase of by setting the variables
+*g:nrrw_rgn_rel_min* and *g:nrrw_rgn_rel_max*
+
+Whether an absolute or relative increase will be performed, is determined by
+the |g:nrrw_rgn_resize_window| variable (see above).
+------------------------------------------------------------------------------
+
+By default, NarrowRegion highlights the region that has been selected
+using the WildMenu highlighting (see |hl-WildMenu|). If you'd like to use a
+different highlighting, set the variable g:nrrw_rgn_hl to your preferred
+highlighting Group. For example to have the region highlighted like a search
+result, you could set *g:nrrw_rgn_hl* in your |.vimrc| >
+
+    let g:nrrw_rgn_hl = 'Search'
+<
+(default: WildMenu)
+
+If you want to turn off the highlighting (because this can be distracting), you
+can set the global variable *g:nrrw_rgn_nohl* to 1 in your |.vimrc| >
+
+    let g:nrrw_rgn_nohl = 1
+<
+(default: 0)
+------------------------------------------------------------------------------
+
+If you'd like to change the key combination that starts the Narrowed Window
+for your selected range, you could map *<Plug>NrrwrgnDo* in your |.vimrc| >
+
+   xmap <F3> <Plug>NrrwrgnDo
+<
+This will let <F3> open the Narrow-Window, but only if you have pressed it in
+Visual Mode. It doesn't really make sense to map this combination to any other
+mode, unless you want it to Narrow your last visually selected range.
+
+(default: <Leader>nr)
+------------------------------------------------------------------------------
+
+If you'd like to specify the options that you want to have set for the
+narrowed window, you can set the *g:nrrw_custom_options* setting, in your
+|.vimrc| e.g. >
+
+   let g:nrrw_custom_options={}
+   let g:nrrw_custom_options['filetype'] = 'python'
+>
+This will only apply those options to the narrowed buffer. You need to take
+care that all options you need will apply.
+
+------------------------------------------------------------------------------
+
+If you don't like that your narrowed window opens above the current window,
+define the *g:nrrw_topbot_leftright* variable to your taste, e.g. >
+
+  let g:nrrw_topbot_leftright = 'botright'
+<
+Now, all narrowed windows will appear below the original window. If not
+specified, the narrowed window will appear above/left of the original window.
+
+(default: topleft)
+------------------------------------------------------------------------------
+
+If you want to use several independent narrowed regions of the same buffer
+that you want to write at the same time, protecting the original buffer is not
+really useful. Therefore, set the *g:nrrw_rgn_protect* variable, e.g. in your
+|.vimrc| >
+
+   let g:nrrw_rgn_protect = 'n'
+<
+This can be useful if you diff different regions of the same file, and want
+to be able to put back the changes at different positions. Please note that
+you should take care not to change any part that will later be influenced
+when writing the narrowed region back.
+
+Note: Don't use overlapping regions! Your changes will probably not be put
+back correctly and there is no guard against losing data accidentally. NrrwRgn
+tries hard to adjust the highlighting and regions as you write your changes
+back into the original buffer, but it can't guarantee that this will work and
+might fail silently. Therefore, this feature is experimental!
+
+(default: y)
+------------------------------------------------------------------------------
+
+If you are using the |:NRMulti| command and want to have the original window
+update to the position of where the cursor is in the narrowed window, you can
+set the variable *g:nrrw_rgn_update_orig_win,* e.g. in your |.vimrc| >
+
+   let g:nrrw_rgn_update_orig_win = 1
+<
+Now the cursor in the original window will always update when the position
+changes in the narrowed window (using a |CursorMoved| autocommand).
+Note: that this might slow down scrolling and cursor movement a bit.
+
+(default: 0)
+------------------------------------------------------------------------------
+
+By default, NarrowRegion plugin defines the two mappings <Leader>nr in visual
+mode and normal mode and <Leader>Nr only in visual mode. If you have your own
+mappings defined, than NarrowRegion will complain about the key already being
+defined. Chances are, this will be quite annoying to you, so you can disable
+mappings those keys by defining the variables *g:nrrw_rgn_nomap_nr* and
+*g:nrrw_rgn_nomap_Nr* in your |.vimr| >
+
+  :let g:nrrw_rgn_nomap_nr = 1
+  :let g:nrrw_rgn_nomap_Nr = 1
+

+                                                 *NrrwRgn-hook*  *NR-hooks*
+
+NarrowRegion can execute certain commands, when creating the narrowed window
+and when closing the narrowed window. For this, you can set 2 buffer-local
+variables that specify what commands to execute, which will hook into the
+execution of the Narrow Region plugin.
+
+For example, suppose you have a file, containing columns separated data (CSV
+format) which you want to modify and you also have the CSV filetype plugin
+(http://www.vim.org/scripts/script.php?script_id=2830) installed and you want
+to modify the CSV data which should be visually arranged like a table in the
+narrowed window.
+
+Therefore you want the command |:ArrangeColumn| to be executed in the new
+narrowed window upon entering it, and when writing the changes back, you want
+the command |:UnArrangeColumn| to be executed just before putting the
+changes back. So you set the two variables *b:nrrw_aucmd_create* and
+*b:nrrw_aucmd_close* in your original buffer: >
+
+    let b:nrrw_aucmd_create = "set ft=csv|%ArrangeCol"
+    let b:nrrw_aucmd_close  = "%UnArrangeColumn"
+<
+This will execute the commands in the narrowed window: >
+
+    :set ft=csv
+    :%ArrangeCol
+
+and before writing the changes back, it'll execute: >
+
+    :%UnArrangeCol
+
+Note: These hooks are executed in the narrowed window (i.e. after creating the
+narrowed window and its content and before writing the changes back to the
+original buffer).
+
+Additional hooks *b:nrrw_aucmd_writepost* and *b:nrrw_aucmd_written* are
+provided, when the data is written back in the original window: the first one
+is executed in the narrowed window, while the second one in the original one
+(the one where the narrowed region was created from).  For example, consider
+you want the execute the command |:make| in the narrowed window, and also write
+the original buffer, whenever the narrowed window is written back to the
+original window. You therefore set: >
+    
+    :let b:nrrw_aucmd_writepost = ':make'
+    :let b:nrrw_aucmd_written = ':update'
+<
+This will run |:make| in the narrowed window and also |:update| the original
+buffer, whenever it was modified after writing the changes from the narrowed
+window back.
+
+2.4 NrrwRgn functions                                    *NrrwRgn-func*
+---------------------
+The NrrwRgn plugin defines a public function in its namespace that can be used
+to query its status.
+                                                        *nrrwrgn#NrrwRgnStatus()*
+nrrwrgn#NrrwRgnStatus()
+    Returns a dict with the following keys:
+        'shortname':    The displayed buffer name
+        'fullname':     The complete buffer name of the original buffer
+        'multi':        1 if it is a multi narrowed window (|:NRMulti|),
+                        0 otherwise.
+        'startl':       List of start lines for a multi narrowed window
+                        (only present, if 'multi' is 1)
+        'endl':         List of end lines for a multi narrowed window
+                        (only present, if 'multi' is 1)
+        'start':        Start position (only present if 'multi' is 0)
+        'end':          End position (only present if 'multi' is 0)
+        'visual':       Visual Mode, if it the narrowed window was started
+                        from a visual selected region (empty otherwise).
+        'enabled':      Whether syncing the buffer is enabled (|:NRS|)
+                            
+    If not executed in a narrowed window, returns an empty dict.

+3. NrrwRgn Tips                                           *NrrwRgn-tips*
+
+To have the filetype in the narrowed window set, you can use this function: >
+
+  command! -nargs=* -bang -range -complete=filetype NN
+              \ :<line1>,<line2> call nrrwrgn#NrrwRgn('',<q-bang>)
+              \ | set filetype=<args>
+<
+This lets you select a region, call :NN sql and the selected region will get
+the sql filetype set.

+(issues to work on, in the order of importance):
+
+- clean up does not work? (instn data isn't removed after :wq in narrowed window)
+
+- When disabling Narrowing using :NRN and one quits the buffer,
+  should the highlighting be removed? (it doesn't yet)
+
+- I really need some tests, like:
+  * Visual Narrowing
+  * Narrowing 1 Region
+  * Narrowing several independent regions with setting the g:nrrw_rgn_protect
+    variable
+  * Multi line narrowing
+
+### Resolved
+- When switching buffers using :b in the window, that was narrowed, the highlighting is keept.
+  (should be resolved)
+
+- highlighting wrong for char visual mode
+ (e.g. select a word, press \nr and the whole line will be highlighted)
+
+- Use nrrwrgn#NrrwRgnStatus() to make a nice statusline for e.g. vim-airline
+-> latest airline supports a nice statusline for narrowed window
+
+- Implement MultiEditing for :NRM
+  (see https://github.com/felixr/vim-multiedit/blob/master/plugin/multiedit.vim
+   and http://blog.felixriedel.com/2012/06/multi-editing-in-vim/)
+  -> Invalid: multiple cursors is different, not part of a narrowed feature
+
+- New Mapping. The motion over which one moves will be opened in a narrowed window.
+  -> <leader>nr in normal mode

+# Diffview.nvim
+
+Single tabpage interface for easily cycling through diffs for all modified files
+for any git rev.
+
+![preview](https://user-images.githubusercontent.com/2786478/131269942-e34100dd-cbb9-48fe-af31-6e518ce06e9e.png)
+
+
+## Introduction
+
+Vim's diff mode is pretty good, but there is no convenient way to quickly bring
+up all modified files in a diffsplit. This plugin aims to provide a simple,
+unified, single tabpage interface that lets you easily review all changed files
+for any git rev.
+
+## Requirements
+
+- Git ≥ 2.31.0 (for Git support)
+- Mercurial ≥ 5.4.0 (for Mercurial support)
+- Neovim ≥ 0.7.0 (with LuaJIT)
+- [nvim-web-devicons](https://github.com/nvim-tree/nvim-web-devicons) (optional) For file icons
+
+## Installation
+
+Install the plugin with your package manager of choice.
+
+```vim
+" Plug
+Plug 'sindrets/diffview.nvim'
+```
+
+```lua
+-- Packer
+use "sindrets/diffview.nvim" 
+```
+
+## Merge Tool
+
+![merge tool showcase](https://user-images.githubusercontent.com/2786478/188286293-13bbf0ab-3595-425d-ba4a-12f514c17eb6.png)
+
+Opening a diff view during a merge or a rebase will list the conflicted files in
+their own section. When opening a conflicted file, it will open in a 3-way diff
+allowing you to resolve the merge conflicts with the context of the target
+branch's version, as well as the version from the branch which is being merged.
+
+The 3-way diff is only the default layout for merge conflicts. There are
+multiple variations on this layout, a 4-way diff layout, and a single window
+layout available.
+
+In addition to the normal `:h copy-diffs` mappings, there are default mappings
+provided for jumping between conflict markers, obtaining a hunk directly from
+any of the diff buffers, and accepting any one, all, or none of the versions of
+a file given by a conflict region.
+
+For more information on the merge tool, mappings, layouts and how to
+configure them, see:
+
+- `:h diffview-merge-tool`
+- `:h diffview-config-view.x.layout`
+
+## File History
+
+![file history showcase](https://user-images.githubusercontent.com/2786478/188331057-f9ec9a0d-8cda-4ff8-ac98-febcc7aa4010.png)
+
+The file history view allows you to list all the commits that affected a given
+set of paths, and view the changes made in a diff split. This is a porcelain
+interface for git-log, and supports a good number of its options. Things like:
+
+- Filtering commits by grepping commit messages and commit authors.
+- Tracing the line evolution of a given set of line ranges for multiple files.
+- Only listing changes for a specific commit range, branch, or tag.
+- Following file changes through renames.
+
+Get started by opening file history for:
+
+- The current branch: `:DiffviewFileHistory`
+- The current file: `:DiffviewFileHistory %`
+
+For more info, see `:h :DiffviewFileHistory`.
+
+## Usage
+
+### `:DiffviewOpen [git rev] [options] [ -- {paths...}]`
+
+Calling `:DiffviewOpen` with no args opens a new Diffview that compares against
+the current index. You can also provide any valid git rev to view only changes
+for that rev.
+
+Examples:
+
+- `:DiffviewOpen`
+- `:DiffviewOpen HEAD~2`
+- `:DiffviewOpen HEAD~4..HEAD~2`
+- `:DiffviewOpen d4a7b0d`
+- `:DiffviewOpen d4a7b0d^!`
+- `:DiffviewOpen d4a7b0d..519b30e`
+- `:DiffviewOpen origin/main...HEAD`
+
+You can also provide additional paths to narrow down what files are shown:
+
+- `:DiffviewOpen HEAD~2 -- lua/diffview plugin`
+
+For information about additional `[options]`, visit the
+[documentation](https://github.com/sindrets/diffview.nvim/blob/main/doc/diffview.txt).
+
+Additional commands for convenience:
+
+- `:DiffviewClose`: Close the current diffview. You can also use `:tabclose`.
+- `:DiffviewToggleFiles`: Toggle the file panel.
+- `:DiffviewFocusFiles`: Bring focus to the file panel.
+- `:DiffviewRefresh`: Update stats and entries in the file list of the current
+  Diffview.
+
+With a Diffview open and the default key bindings, you can cycle through changed
+files with `<tab>` and `<s-tab>` (see configuration to change the key bindings).
+
+#### Staging
+
+You can stage individual hunks by editing any buffer that represents the index
+(after running `:DiffviewOpen` with no `[git-rev]` the entries under "Changes"
+will have the index buffer on the left side, and the entries under "Staged
+changes" will have it on the right side). Once you write to an index buffer the
+index will be updated.
+
+### `:[range]DiffviewFileHistory [paths] [options]`
+
+Opens a new file history view that lists all commits that affected the given
+paths. This is a porcelain interface for git-log. Both `[paths]` and
+`[options]` may be specified in any order, even interchangeably.
+
+If no `[paths]` are given, defaults to the top-level of the working tree. The
+top-level will be inferred from the current buffer when possible, otherwise the
+cwd is used. Multiple `[paths]` may be provided and git pathspec is supported.
+
+If `[range]` is given, the file history view will trace the line evolution of the
+given range in the current file (for more info, see the `-L` flag in the docs).
+
+Examples:
+
+- `:DiffviewFileHistory`
+- `:DiffviewFileHistory %`
+- `:DiffviewFileHistory path/to/some/file.txt`
+- `:DiffviewFileHistory path/to/some/directory`
+- `:DiffviewFileHistory include/this and/this :!but/not/this`
+- `:DiffviewFileHistory --range=origin..HEAD`
+- `:DiffviewFileHistory --range=feat/example-branch`
+- `:'<,'>DiffviewFileHistory`
+
+> [!IMPORTANT]
+> ### Familiarize Yourself With `:h diff-mode`
+>
+> This plugin assumes you're familiar with all the features already provided by
+> nvim's builtin diff-mode. These features include:
+>
+> - Jumping between hunks (`:h jumpto-diffs`).
+> - Applying the changes of a diff hunk from any of the diffed buffers
+>   (`:h copy-diffs`).
+> - And more...
+>
+> Read the help page for more info.

+
+### Hooks
+
+The `hooks` table allows you to define callbacks for various events emitted from
+Diffview. The available hooks are documented in detail in
+`:h diffview-config-hooks`. The hook events are also available as User
+autocommands. See `:h diffview-user-autocmds` for more details.
+
+Examples:
+
+```lua
+hooks = {
+  diff_buf_read = function(bufnr)
+    -- Change local options in diff buffers
+    vim.opt_local.wrap = false
+    vim.opt_local.list = false
+    vim.opt_local.colorcolumn = { 80 }
+  end,
+  view_opened = function(view)
+    print(
+      ("A new %s was opened on tab page %d!")
+      :format(view.class:name(), view.tabpage)
+    )
+  end,
+}
+```
+
+### Keymaps
+
+The keymaps config is structured as a table with sub-tables for various
+different contexts where mappings can be declared. In these sub-tables
+key-value pairs are treated as the `{lhs}` and `{rhs}` of a normal mode
+mapping. These mappings all use the `:map-arguments` `silent`, `nowait`, and
+`noremap`. The implementation uses `vim.keymap.set()`, so the `{rhs}` can be
+either a vim command in the form of a string, or it can be a lua function:
+
+```lua
+  view = {
+    -- Vim command:
+    ["a"] = "<Cmd>echom 'foo'<CR>",
+    -- Lua function:
+    ["b"] = function() print("bar") end,
+  }
+```
+
+For more control (i.e. mappings for other modes), you can also define index
+values as list-like tables containing the arguments for `vim.keymap.set()`.
+This way you can also change all the `:map-arguments` with the only exception
+being the `buffer` field, as this will be overridden with the target buffer
+number:
+
+```lua
+view = {
+  -- Normal and visual mode mapping to vim command:
+  { { "n", "v" }, "<leader>a", "<Cmd>echom 'foo'<CR>", { silent = true } },
+  -- Visual mode mapping to lua function:
+  { "v", "<leader>b", function() print("bar") end, { nowait = true } },
+}
+```
+
+To disable any single mapping without disabling them all, set its `{rhs}` to
+`false`:
+
+```lua
+  view = {
+    -- Disable the default normal mode mapping for `<tab>`:
+    ["<tab>"] = false,
+    -- Disable the default visual mode mapping for `gf`:
+    { "x", "gf", false },
+  }
+```
+
+Most of the mapped file panel actions also work from the view if they are added
+to the view maps (and vice versa). The exception is for actions that only
+really make sense specifically in the file panel, such as `next_entry`,
+`prev_entry`. Actions such as `toggle_stage_entry` and `restore_entry` work
+just fine from the view. When invoked from the view, these will target the file
+currently open in the view rather than the file under the cursor in the file
+panel.
+
+**For more details on how to set mappings for other modes, actions, and more see:**
+- `:h diffview-config-keymaps`
+- `:h diffview-actions`
+
+## Restoring Files
+
+If the right side of the diff is showing the local state of a file, you can
+restore the file to the state from the left side of the diff (key binding `X`
+from the file panel by default). The current state of the file is stored in the
+git object database, and a command is echoed that shows how to undo the change.
+
+## Tips and FAQ
+
+- **Hide untracked files:**
+  - `DiffviewOpen -uno`
+- **Exclude certain paths:**
+  - `DiffviewOpen -- :!exclude/this :!and/this`
+- **Run as if git was started in a specific directory:**
+  - `DiffviewOpen -C/foo/bar/baz`
+- **Diff the index against a git rev:**
+  - `DiffviewOpen HEAD~2 --cached`
+  - Defaults to `HEAD` if no rev is given.
+- **Q: How do I get the diagonal lines in place of deleted lines in
+  diff-mode?**
+  - A: Change your `:h 'fillchars'`:
+    - (vimscript): `set fillchars+=diff:╱`
+    - (Lua): `vim.opt.fillchars:append { diff = "╱" }`
+  - Note: whether or not the diagonal lines will line up nicely will depend on
+    your terminal emulator. The terminal used in the screenshots is Kitty.
+- **Q: How do I jump between hunks in the diff?**
+  - A: Use `[c` and `]c`
+  - `:h jumpto-diffs`

+# Usage
+
+This document contains a few guides for solving common problems, and describes
+some more specific use-cases.
+
+## Review a PR
+
+### Comparing All the Changes
+
+First, checkout the branch locally. If it's a GitHub PR, you can use
+[`gh`](https://github.com/cli/cli) to do this:
+
+```console
+$ gh pr checkout {PR_ID}
+```
+
+Now, run a symmetric diff against the base branch:
+
+```vim
+:DiffviewOpen origin/HEAD...HEAD --imply-local
+```
+
+The symmetric difference rev range (triple dot) will here compare the changes on
+the current branch (the PR branch) against its merge-base in `origin/HEAD`. This
+is different from comparing directly against `origin/HEAD` if the branches have
+diverged, and is usually what you want when comparing changes in a PR. For more
+info see the section on "SPECIFYING REVISIONS" in `man git-rev-parse(1)`.
+
+The `--imply-local` flag option will here make diffview.nvim show the working
+tree versions[^1] of the changed files on the right side of the diff. This means
+that if you have tools such as LSP set up, it will work for all the diff buffers
+on the right side, giving you access to LSP features - such as diagnostics and
+references - that can be useful while reviewing changes.
+
+If you want the plugin to always use this option, you can add it to your default
+args:
+
+```lua
+default_args = {
+  DiffviewOpen = { "--imply-local" },
+}
+```
+
+From the file panel you can press `L` to open the commit log for all the
+changes. This lets you check the full commit messages for all the commits
+involved.
+
+![diffview symdiff demo](https://user-images.githubusercontent.com/2786478/229858634-c751ebe3-cc43-48de-adda-bf0b71fa2ce7.png)
+
+> NOTE: If Git complains `fatal: Not a valid object name origin/HEAD` then it
+> likely means that your local origin remote doesn't have a default branch
+> configured. You can have Git automatically query your remote and detect its
+> default branch like this:
+>
+> ```sh
+> git remote set-head -a origin
+> ```
+
+[^1]: The files as they currently exist on disk.
+
+### Comparing Changes From the Individual PR Commits
+
+If you're reviewing a big PR composed of many commits, you might prefer to
+review the changes introduced in each of those commits individually. To do
+this, you can use `:DiffviewFileHistory`:
+
+```vim
+:DiffviewFileHistory --range=origin/HEAD...HEAD --right-only --no-merges
+```
+
+Here we are again using a symmetric difference range. However, symdiff ranges
+have different behavior between `git-diff` and `git-log`. Whereas in `git-diff`
+it compares against the merge-base, here it will select only the commits that
+are reachable from _either_ `origin/HEAD` _or_ `HEAD`, but not from both (in
+other words, it's actually performing a symmetric difference here).
+
+We then use the cherry-pick option `--right-only` to limit the commits to only
+those on the right side of the symmetric difference. Finally `--no-merges`
+filters out merge commits. We are left with a list of all the non-merge commits
+from the PR branch.
+
+![file history cherry pick demo](https://user-images.githubusercontent.com/2786478/229853402-f45280ee-f6e2-4325-8a39-ce25b9c5221e.png)
+
+## Inspecting Diffs for Stashes
+
+The latest Git stash is always stored in the reference `refs/stash`. We can
+find all the stashes by traversing the reflog for this reference. This can be
+achieved with the flag option `--walk-reflogs` (or it's short form `-g`). The
+following command will list all stashes in the file history panel:
+
+```vim
+:DiffviewFileHistory -g --range=stash
+```
+
+## Committing
+
+Creating commits from within nvim is a solved problem, and as such diffview.nvim
+does not reinvent the wheel here. Here are a few different ways in which you can
+create a new commit from within the editor:
+
+### Use a Git Wrapper Plugin (Recommended)
+
+Diffview.nvim _is not_, and _does not try to be_ a complete git wrapper. As
+such, there are a number of features offered by such plugins that won't ever be
+implemented here, because they are deemed out-of-scope. It's therefore
+recommended to use some form of a Git wrapper plugin in order to get a more
+complete integration of Git's features into your editor. Here are a few options:
+
+- [`vim-fugitive`](https://github.com/tpope/vim-fugitive)
+- [`neogit`](https://github.com/TimUntersberger/neogit)
+- [`lazygit.nvim`](https://github.com/kdheepak/lazygit.nvim)
+
+Example creating some `vim-fugitive` mappings for committing staged changes
+from the file panel:
+
+```lua
+keymaps = {
+  file_panel = {
+    {
+      "n", "cc",
+      "<Cmd>Git commit <bar> wincmd J<CR>",
+      { desc = "Commit staged changes" },
+    },
+    {
+      "n", "ca",
+      "<Cmd>Git commit --amend <bar> wincmd J<CR>",
+      { desc = "Amend the last commit" },
+    },
+    {
+      "n", "c<space>",
+      ":Git commit ",
+      { desc = "Populate command line with \":Git commit \"" },
+    },
+  },
+}
+```
+
+### Use [`neovim-remote`](https://github.com/mhinz/neovim-remote)
+
+`neovim-remote` is a more complete version of the builtin `:h clientserver`.
+Notably it implements all the `:h clientserver-missing` functionality. Hopefully
+this functionality will be implemented in core at some point in the future. But
+until then this separate application is needed to get the `--{...}-wait`
+variants of the remote options.
+
+With the remote installed you can simply configure your `$GIT_EDITOR`
+environment variable from within the editor such that when the Git editor is
+invoked, it will open in a new split inside the current editor session. This
+avoids the problem of spawning nested nvim instances every time an `$EDITOR` is
+invoked. Put this somewhere in your `init.lua`:
+
+```lua
+if vim.fn.executable("nvr") == 1 then
+  local nvr = "nvr --servername " .. vim.v.servername .. " "
+  vim.env.GIT_EDITOR = nvr .. "-cc split +'setl bh=delete' --remote-wait"
+  vim.env.EDITOR = nvr .. "-l --remote" -- (Optional)
+  vim.env.VISUAL = nvr .. "-l --remote" -- (Optional)
+end
+```
+
+Example creating some mappings for committing staged changes from the file
+panel, that will trigger `nvr`:
+
+```lua
+keymaps = {
+  file_panel = {
+    {
+      "n", "cc",
+      [[<Cmd>call jobstart(["git", "commit"]) | au BufWinEnter * ++once wincmd J<CR>]],
+      { desc = "Commit staged changes" },
+    },
+    {
+      "n", "ca",
+      [[<Cmd>call jobstart(["git", "commit", "--amend"]) | au BufWinEnter * ++once wincmd J<CR>]],
+      { desc = "Amend the last commit" },
+    },
+  },
+}
+```
+
+### Use `:terminal`
+
+The `:h :terminal` command allows you to run interactive terminal jobs. However,
+unlike the [previously discussed](#use-neovim-remote) `neovim-remote` solution
+this will spawn nested instances of nvim.
+
+Example creating some `:terminal` mappings for committing staged changes from
+the file panel:
+
+```lua
+keymaps = {
+  file_panel = {
+    {
+      "n", "cc",
+      "<Cmd>sp <bar> wincmd J <bar> term git commit<CR>",
+      { desc = "Commit staged changes" },
+    },
+    {
+      "n", "ca",
+      "<Cmd>sp <bar> wincmd J <bar> term git commit -amend<CR>",
+      { desc = "Amend the last commit" },
+    },
+  },
+}
+```
+
+### Use `vim.ui.input()`
+
+This example shows how to use the Neovim builtin `vim.ui.input()` to create a
+simple input prompt, and create a new commit with the user's given message.
+
+![vim.ui.input() demo](https://user-images.githubusercontent.com/2786478/274230878-661a30d5-cc1d-4a34-b196-c4adf9e9f8c5.gif)
+
+For Neovim ≥ v0.10:
+
+```lua
+keymaps = {
+  file_panel = {
+    {
+      "n", "cc",
+      function()
+        vim.ui.input({ prompt = "Commit message: " }, function(msg)
+          if not msg then return end
+          local results = vim.system({ "git", "commit", "-m", msg }, { text = true }):wait()
+
+          if results.code ~= 0 then
+            vim.notify(
+              "Commit failed with the message: \n"
+                .. vim.trim(results.stdout .. "\n" .. results.stderr),
+              vim.log.levels.ERROR,
+              { title = "Commit" }
+            )
+          else
+            vim.notify(results.stdout, vim.log.levels.INFO, { title = "Commit" })
+          end
+        end)
+      end,
+    },
+  },
+}
+```
+
+<details>
+  <summary><b>For Neovim ≤ v0.10, use this function in place of <code>vim.system()</code></b></summary>
+
+```lua
+--- @class system.Results
+--- @field code integer
+--- @field stdout string
+--- @field stderr string
+
+--- @param cmd string|string[]
+--- @return system.Results
+local function system(cmd)
+  local results = {}
+
+  local function callback(_, data, event)
+    if event == "exit" then results.code = data
+    elseif event == "stdout" or event == "stderr" then
+      results[event] = table.concat(data, "\n")
+    end
+  end
+
+  vim.fn.jobwait({
+    vim.fn.jobstart(cmd, {
+      on_exit = callback,
+      on_stdout = callback,
+      on_stderr = callback,
+      stdout_buffered = true,
+      stderr_buffered = true,
+    })
+  })
+
+  return results
+end
+```
+</details>
+
+### Use `:!cmd`
+
+If you only ever write simple commit messages you could make use of `:h !cmd`:
+
+```vim
+:!git commit -m 'some commit message'
+```

+
+Single tabpage interface to easily cycle through diffs for all modified files
+for any git rev.
+
+Author: Sindre T. Strøm
+
+==============================================================================
+
+INTRODUCTION                                    *diffview.nvim* *diffview*
+
+Vim's diff mode is pretty good, but there is no convenient way to quickly bring
+up all modified files in a diffsplit. This plugin aims to provide a simple,
+unified, single tabpage interface that lets you easily review all changed files
+for any git rev.
+
+==============================================================================
+
+USAGE                                           *diffview-usage*
+
+Quick-start: `:DiffviewOpen` to open a Diffview that compares against the
+index.
+
+You can have multiple Diffviews open, tracking different git revs. Each Diffview
+opens in its own tabpage. To close and dispose of a Diffview, call either
+`:DiffviewClose` or `:tabclose` while a Diffview is the current tabpage.
+Diffviews are automatically updated:
+
+        • Every time you enter a Diffview
+        • Whenever `.git/index` changes.
+        • On |BufWritePost|
+        • On |User_FugitiveChanged|
+
+Updates are not run unless the current tabpage is a Diffview.
+
+NOTE: Familiarize yourself with |diff-mode|. This plugin assumes you're
+familiar with all the features already provided by nvim's builtin diff-mode.
+These features include:
+
+        • Jumping between hunks (|jumpto-diffs|).
+        • Applying the changes of a diff hunk from any of the diffed buffers
+          (|copy-diffs|).
+        • And more...
+
+Visit the help page for more info.
+
+------------------------------------------------------------------------------
+
+COMMANDS                                        *diffview-commands*
+
+                                                *:DiffviewOpen*
+:DiffviewOpen [git-rev] [options] [ -- {paths...}]
+
+        Opens a new Diffview that compares against [git-rev]. If no [git-rev]
+        is given, defaults to comparing against the index. Additional
+        {paths...} may be provided to narrow down what files are shown. If the
+        `-C` flag is not defined, the git top-level is determined from the
+        current buffer when possible. Otherwise it's determined from the cwd.
+
+        Examples: >vim
+
+            " Diff the working tree against the index:
+            :DiffviewOpen
+
+            " Diff the working tree against a specific commit:
+            :DiffviewOpen HEAD~2
+            :DiffviewOpen d4a7b0d
+
+            " Diff a commit range:
+            :DiffviewOpen HEAD~4..HEAD~2
+            :DiffviewOpen d4a7b0d..519b30e
+
+            " Diff the changes introduced by a specific commit (kind of like
+            " `git show d4a7b0d`):
+            :DiffviewOpen d4a7b0d^!
+
+            " Diff HEAD against it's merge base in origin/main:
+            :DiffviewOpen origin/main...HEAD
+
+            " Limit the scope to the given paths:
+            :DiffviewOpen HEAD~2 -- lua/diffview plugin
+
+            " Hide untracked files:
+            :DiffviewOpen -uno
+<
+
+                                                *diffview-staging*
+        You can stage individual hunks by editing any buffer that represents
+        the index (after running `:DiffviewOpen` with no [git-rev] the entries
+        under "Changes" will have the index buffer on the left side, and the
+        entries under "Staged changes" will have it on the right side). Once
+        you write to an index buffer the index will be updated.
+
+                                                *diffview-merge-tool*
+        If you call `:DiffviewOpen` during a merge or a rebase, the view will
+        list the conflicted files in their own section. When opening a
+        conflicted file, it will open in a 3-way diff allowing you to resolve
+        the conflict with the context of the target branch's version (OURS,
+        left), and the version from the branch which is being merged (THEIRS,
+        right).
+
+        The conflicted file's entry in the file panel will show the
+        remaining number of conflict markers (the number following the file
+        name). If what follows the file name is instead an exclamation mark
+        (`!`), this indicates that the file has not yet been opened, and the
+        number of conflicts is unknown. If the sign is a check mark, this
+        indicates that there are no more conflicts in the file.
+
+        You can jump between conflict markers with `]x` and `[x`. This works
+        from the file panel as well. Further, in addition to the normal
+        |copy-diffs| mappings you can use `2do` to obtain the hunk from the
+        OURS side of the diff, `3do` to obtain the hunk from the THEIRS side
+        of the diff, and - in a 4-way diff - `1do` to obtain the hunk from the
+        BASE. See |diffview-conflict-versions| to tell what windows correspond
+        with what version of the file.
+
+        Additionally there are mappings for operating directly on the conflict
+        markers:
+          • `<leader>co`: Choose the OURS version of the conflict.
+          • `<leader>ct`: Choose the THEIRS version of the conflict.
+          • `<leader>cb`: Choose the BASE version of the conflict.
+          • `<leader>ca`: Choose all versions of the conflict (effectively
+            just deletes the markers, leaving all the content).
+          • `dx`: Choose none of the versions of the conflict (delete the
+            conflict region).
+
+        For more info on these actions, see
+        |diffview-actions-conflict_choose|.
+
+        NOTE: The horizontal 3-way diff is only the default layout for the
+        merge-tool, but there are multiple variations on the 3-way diff layout
+        as well as a 4-way diff, and a single window layout available. The
+        default mapping `g<C-x>` allows you to cycle through the available
+        layouts. To configure a different default layout, see
+        |diffview-config-view.x.layout|.
+
+    Options: ~
+        -u[value], --untracked-files[={value}]
+                        Specify whether or not to show untracked files. If
+                        flag is given without value; defaults to `true`.
+                        {value} can be one of:
+                          • `true`, `normal`, `all` Show untracked.
+                          • `false`, `no` Don't show untracked.
+        --cached, --staged
+                        Diff staged changes against [git-rev]. If no [git-rev]
+                        is given, defaults to `HEAD`.
+
+        --imply-local   If a range rev is provided and either end of the range
+                        points to `HEAD`: point that end to local files
+                        instead (not created from git). This can be useful
+                        i.e. when using symmetric difference ranges
+                        (triple-dot), but you want to be able to utilize the
+                        LSP features that are not available while you're
+                        viewing files created from git.
+
+        -C{path}        Run as if git was started in {path} instead of the
+                        current working directory.
+
+        --selected-file={path}
+                        Specify a path to the preferred initially selected
+                        file. If the path doesn't match any of the files in
+                        the initial set of files, this option does nothing.
+
+                                                *:DiffviewFileHistory*
+:[range]DiffviewFileHistory [paths] [options]
+
+        Opens a new file history view that lists all commits that affected the
+        given paths. This is a porcelain interface for git-log. Both [paths]
+        and [options] may be specified in any order, even interchangeably.
+
+        If no [paths] are given, defaults to the top-level of the working
+        tree. The top-level will be inferred from the current buffer when
+        possible, otherwise the cwd is used. Multiple [paths] may be provided
+        and git pathspec is supported (see `:Man gitglossary(7)` for
+        information about pathspec).
+
+        If [range] is given, the file history view will trace the line
+        evolution of the given range in the current file (see the `-L` flag
+        below).
+
+        From the file history panel (the panel listing the commits) you can
+        open an option panel by pressing `g!`. The option panel will allow you
+        to change the flags that will be passed to `git-log`. A flag can be
+        adjusted either by moving the cursor to its line followed by pressing
+        <Tab>, or by using the mappings that are shown directly in the panel,
+        preceding the flags' descriptions.
+
+                                                *diffview-inspect-stash*
+        The latest Git stash is always stored in the reference `refs/stash`.
+        We can find all the stashes by traversing the reflog for this
+        reference. This can be achieved with the flag option `--walk-reflogs`
+        (or it's short form `-g`). The following command will list all stashes
+        in the file history panel: >
+                :DiffviewFileHistory -g --range=stash
+<

+                on the "other side" when the set of commits are limited with
+                symmetric difference.
+
+        --left-only

+                You can specify this option more than once.
+
+        --diff-merges={value}
+                Determines how merge commits are treated. {value} can

+        Type: `boolean`, Default: `false`
+
+        Enable/disable enhanced diff highlighting. This option has slightly
+        different effects in different |diffview-layouts|.
+
+        In all layouts: highlight delete fill-chars more subtly. These chars
+            are used as filler in places where other diff buffers have
+            insertions at that postion. Unfortunately many color schemes give
+            it a distracting highlight, such as a bright red. This makes diffs
+            more difficult to visually parse, as your eyes get drawn towards
+            the bright red areas of your display with absolutely no
+            information in them.
+
+        In `diff2*` layouts: show |hl-DiffAdd| as |hl-DiffDelete| in the
+            buffer representing the old state. This makes the highlighting
+            more inline with how 2-way diffs are displayed in other diff
+            tools. As - in a 2-way diff - an "insertion" in the old state
+            actually represents a deletion from the perspective of the new
+            state.

+
+        This table forms the first part of all Git commands used internally in

+
+        This table forms the first part of all Mercurial commands used
+        internally in the plugin. The first element should be the Mercurial
+        binary. The subsequent elements are passed as arguments.
+
+        If your Mercurial install bundles the `chg` binary, this can be
+        configured here to have a significant performance boost.

+        Type: `boolean`, Default: (see defaults)
+
+        Use the 'winbar' to show contextual info about the different versions
+        of a file in a diff.
+
+                                                *diffview-config-view.x.disable_diagnostics*
+view.x.disable_diagnostics
+        Type: `boolean`, Default: (see defaults)
+
+        Temporarily disable diagnostics for diff buffers while in a view. The
+        diagnostics are automatically enabled again when leaving or closing
+        the view's tab page.
+
+win_config                                      *diffview-config-win_config*
+        Type: `table | fun(): table`, Default: `{}`
+
+        This is used to configure the windows of the various panels in the
+        plugin. If this is set to a function, it should return the config
+        table when called (usually whenever the panel opens). If
+        `type="float"`, then this should be the config table passed to
+        |nvim_open_win()|.
+
+        Certain fields are only applicable for either `type="split"` or
+        `type="float"`. If a field description is designated as "when
+        `type="split"`", then this implies that the field has a different
+        function when `type="float"`. When that is the case, the field's float
+        behavior is documented under |nvim_open_win()|.
+
+        Fields: ~
+            {type} ("split"|"float")
+                Determines whether the window should be a float or a normal
+                split.
+
+            {width} (integer)
+                The width of the window (in character cells). If `type` is
+                `"split"` then this is only applicable when `position` is
+                `"left"|"right"`.
+
+            {height} (integer)
+                The height of the window (in character cells). If `type` is
+                `"split"` then this is only applicable when `position` is
+                `"top"|"bottom"`.
+
+            {position} ("left"|"top"|"right"|"bottom")
+                Determines where the panel is positioned (only when
+                `type="split"`).
+
+            {relative} ("editor"|"win")
+                Determines what the `position` is relative to (when
+                `type="split"`).
+                Default: `"editor"`
+
+            {win} (integer)
+                The window handle of the target relative window (when
+                `type="split"`. Only when `relative="win"`). Use `0` for
+                current window.
+                Default: `0`
+
+            {win_opts} (table)
+                Table of window local options (see |vim.opt_local|).
+                These options are applied whenever the window is opened.
+
+            NOTE: Fields that are only applicable when `type="float"` are not
+            listed here because they are already documented under
+            |nvim_open_win()|.
+
+        Examples: >lua

+        Type: `table`, Default: (see defaults)
+
+        This table allows you to control the default options that are passed
+        to git-log in order to produce the file history. The table is divided
+        into the sub-tables `single_file`, and `multi_file`. This allows you
+        to define different default log options for history targeting singular
+        files, and history targeting multiple paths, and/or directories.
+
+        Fields: ~
+            {single_file} (`LogOptions`)
+                See |diffview.git.LogOptions|.

+        Type: `table<string, string[]>`, Default: `{}`
+
+        This table allows you to define the default args that will always be
+        prepended to the arg-list for the commands specified by the table
+        keys.
+
+        Examples: >lua
+                default_args = {
+                  DiffviewOpen = { "--untracked-files=no", "--imply-local" },

+        Type: `table<string, function>`, Default: `{}`
+
+        This is a table of event names mapped to callback functions. The
+        callbacks are called when the related events are emitted from
+        Diffview. The hook events are also available as User autocommands. See
+        |diffview-user-autocmds| for more details.
+
+        Available Events: ~
+            {view_opened} (`fun(view: View)`)
+                Emitted after a new view has been opened. It's called after
+                initializing the layout in the new tabpage (all windows are
+                ready).
+
+                Callback Parameters: ~
+                    {view} (`View`)
+                        The `View` instance that was opened.
+
+            {view_closed} (`fun(view: View)`)
+                Emitted after closing a view.
+
+                Callback Parameters: ~
+                    {view} (`View`)
+                        The `View` instance that was closed.
+
+            {view_enter} (`fun(view: View)`)
+                Emitted just after entering the tabpage of a view.
+
+                Callback Parameters: ~
+                    {view} (`View`)
+                        The `View` instance that was entered.
+
+            {view_leave} (`fun(view: View)`)
+                Emitted just before leaving the tabpage of a view.
+
+                Callback Parameters: ~
+                    {view} (`View`)
+                        The `View` instance that's about to be left.
+
+            {view_post_layout} (`fun(view: View)`)
+                Emitted after the window layout in a view has been adjusted.
+
+                Callback Parameters: ~
+                    {view} (`View`)
+                        The `View` whose layout was adjusted.
+
+            {diff_buf_read} (`fun(bufnr: integer, ctx: table)`)
+                Emitted after a new diff buffer is ready (the first time it's
+                created and loaded into a window). Diff buffers are all
+                buffers with |diff-mode| enabled. That includes buffers of
+                local files (not created from git).
+
+                This is always called with the new buffer as the current
+                buffer and the correct diff window as the current window such
+                that |:setlocal| will apply settings to the relevant buffer /

+                        • {symbol} (string)
+                          A symbol that identifies the window's position in

+                          figures under |diffview-config-view.x.layout|.
+                        • {layout_name} (string)
+                          The name of the current layout.
+
+            {diff_buf_win_enter} (`fun(bufnr: integer, winid: integer, ctx: table)`)
+                Emitted after a diff buffer is displayed in a window.
+
+                This is always called with the new buffer as the current
+                buffer and the correct diff window as the current window such
+                that |:setlocal| will apply settings to the relevant buffer /
+                window.
+
+                Callback Parameters: ~
+                    {bufnr} (`integer`)
+                        The buffer number of the new buffer.
+                    {winid} (`integer`)
+                        The window id of window inside which the buffer was
+                        displayed.
+                    {ctx} (`table`)
+                        • {symbol} (string)
+                          A symbol that identifies the window's position in
+                          the layout. These symbols correspond with the
+                          figures under |diffview-config-view.x.layout|.
+                        • {layout_name} (string)
+                          The name of the current layout.

+keymaps                                         *diffview-config-keymaps*
+        Type: `table`, Default: (see defaults)
+
+        The keymaps config is structured as a table with sub-tables for
+        various different contexts where mappings can be declared. In these
+        sub-tables key-value pairs are treated as the |{lhs}| and |{rhs}| of a
+        normal mode mapping. These mappings all use the |:map-arguments|
+        `silent`, `nowait`, and `noremap`. The implementation uses
+        |vim.keymap.set()|, so the {rhs} can be either a vim command in the
+        form of a string, or it can be a lua function: >lua
+
+        view = {
+          -- Vim command:
+          ["a"] = "<Cmd>echom 'foo'<CR>",
+          -- Lua function:
+          ["b"] = function() print("bar") end,
+        }
+<
+
+        For more control (i.e. mappings for other modes), you can also define
+        index values as list-like tables containing the arguments for
+        |vim.keymap.set()|. This way you can also change all the
+        |:map-arguments| with the only exception being the `buffer` field, as
+        this will be overridden with the target buffer number: >lua
+
+        view = {
+          -- Normal and visual mode mapping to vim command:
+          { { "n", "v" }, "<leader>a", "<Cmd>echom 'foo'<CR>", { silent = true } },
+          -- Visual mode mapping to lua function:
+          { "v", "<leader>b", function() print("bar") end, { nowait = true } },
+        }
+<
+
+        Setting a mapping's `desc` field to `"diffview_ignore"` will hide the
+        mapping from the help panel: >lua
+
+        view = {
+          -- Ignore mapping in the help panel
+          { "n", "<2-LeftMouse>", actions.select_entry, { desc = "diffview_ignore" } },
+        }
+<
+
+        To disable all the default mappings simply set: >lua
+
+        keymaps = {
+          disable_defaults = true,
+        }
+<
+
+        To disable any single mapping without disabling them all, set its
+        {rhs} to `false`: >lua
+
+        view = {
+          -- Disable the default normal mode mapping for `<tab>`:
+          ["<tab>"] = false,
+          -- Disable the default visual mode mapping for `gf`:
+          { "x", "gf", false },
+        }

+Actions ~
+
+        Actions are key-mappable functions. You can access an action through
+        the config module: >lua
+
+                require("diffview.config").actions.{action_name}
+<
+
+        Where {action_name} is the name of the action you're accessing. Many
+        actions are contextual and will behave slightly differently depending
+        on what context they were called from. The various actions are
+        described with all the contexts in which they have a function.
+        Following are the different contexts described alongside possible
+        subjects, upon which actions called from their context, will act on.
+
+        Contexts: ~

+
+        Like |diffview-actions-goto_file| except after changing tabpage,

+                The 1-based index of the conflict to jump to.
+            {use_delta} (boolean)
+                If true: treat {num} like a relative offset from the current
+                cursor position. I.e. `1` would jump one conflict forward, `-2`
+                would jump 2 conflicts backwards.
+
+        Return: ~
+            If the current file contains any conflicts, the action returns a

+        Contexts: `view`, `panel`
+
+        For `diff_view`:
+
+            Revert the selected file entry to the state from the left side of
+            the diff. This only works if the right side of the diff is showing
+            the local state of the file.
+
+            NOTE: "Restoring" an untracked file will delete it from disk. It
+            still gets backed up in the local git database, so it is
+            reversible.
+
+        For `file_history_view`:
+
+            Revert the selected file to the state it was in, in the selected
+            entry's commit.
+
+        NOTE: A command is echoed that shows how to undo the change. Check
+        |:messages| or |:DiffviewLog| to see it again.

+        Contexts: `view`, `panel`
+
+        Select the subject.
+
+        Think of this as a general "interact" action. In the file panel, and
+        the file history panel, this will open the file under the cursor. If
+        the entry under the cursor is a directory, or a history entry with
+        multiple files, this will collapse or open the entry. In the option
+        panel this will interact with the option under the cursor.

+        Contexts: `view`, `panel`
+
+        Execute {cmd} for each window in the current layout in the current
+        view. The {cmd} will be called with each target window as the
+        temporary current window (|nvim_win_call()|).
+
+        Parameters: ~
+            {cmd} (`string|fun(layout_name: string, symbol: string)`)

+                    {layout_name} (string)
+                        The name of the current layout.
+                    {symbol} (string)
+                        A symbol that identifies the window's position in the
+                        layout. These symbols correspond with the figures
+                        under |diffview-config-view.x.layout|.

+
+`DiffviewViewOpened`    Fires after a new view has been opened. It's called
+                      after initializing the layout in the new tabpage (all
+                      windows are ready).
+
+`DiffviewViewClosed`    Fires after a view is closed.
+
+`DiffviewViewEnter`     Fires just after entering a view.
+
+`DiffviewViewLeave`     Fires just before leaving a view.
+
+`DiffviewViewPostLayout`
+                      Fires just after the window layout in a view has been
+                      adjusted.
+
+`DiffviewDiffBufRead`   Fires after a new diff buffer is ready (the first time
+                      it's created and loaded into a window). Diff buffers are
+                      all buffers with |diff-mode| enabled. That includes
+                      buffers of local files (not created from git).
+
+                      This is always called with the new buffer as the current
+                      buffer and the correct diff window as the current window
+                      such that |:setlocal| will apply settings to the
+                      relevant buffer / window.
+
+`DiffviewDiffBufWinEnter`
+                      Fires after a diff buffer is displayed in a window.
+
+                      This is always called with the new buffer as the current
+                      buffer and the correct diff window as the current window
+                      such that |:setlocal| will apply settings to the
+                      relevant buffer / window.

+MAPS                                            *diffview-maps*
+
+All listed maps are the defaults, but all mappings can be configured. Most of
+the file panel actions should also work from the view if they are added to the
+view bindings (and vice versa). The exception is for actions that only really
+make sense specifically in the file panel, such as `next_entry` and
+`prev_entry`. Actions such as `toggle_stage_entry` and `restore_entry` work
+just fine from the view. When invoked from the view, these will target the
+file currently open in the view rather than the file under the cursor in the
+file panel.

+File inference ~
+
+Actions that target a file will infer the target file according to a set of
+simple rules:
+
+        • If the cursor is in one of the diff buffers, the target file will be the
+          file being compared.
+        • If the cursor is in a file panel, the target file will be determined by
+          the entry under the cursor.

+PR: https://github.com/sindrets/diffview.nvim/pull/271
+
+The config for log options has changed. In preparation of adding support of
+other VCS, the table is now divided into sub-tables per VCS type. This allows

+PR: https://github.com/sindrets/diffview.nvim/pull/190
+
+This PR involves a major refactor of the layout system. The changes are made
+in preparation of the planned merge-tool, which is going to involve 3-way
+diffs, and possibly also 4-way diffs. Different entries in the same view may
+now use completely different window layouts. Thus the action `view_windo` has
+changed to reflect these changes. See |diffview-actions-view_windo| for more
+details on the new usage.

+
+The file history option panel is now able to accept multiple values separated
+by whitespace. This means that if you want to specify values with whitespace,
+you need to quote the value, or escape the whitespace with a backslash (`\`).

+
+The config for log options has changed. The table is now divided into the
+sub-tables `single_file`, and `multi_file`. This allows you to define
+different default log options for history targeting singular files, and
+history targeting multiple paths, and/or directories. To update your config,
+just move all your log options into the new table keys `single_file` and
+`multi_file`:

+You only need to define the options you want to change from the defaults. To

+
+Calling `:DiffviewFileHistory` with no args would previously target the file
+in the current buffer. This has now been changed to instead target the
+top-level of the working tree. This was changed because with how it worked
+before, there was effectively no way to get the file history equivalent of
+running `git log` with no path args. If your cwd was some subdirectory of the
+working tree, and you wanted the full file history of the tree, you would have
+to manually type out the path to the top-level. On the contrary, getting the
+history for the current file is always as simple as just using `%`, which
+expands to the current file name.
+
+To get the file history for the current file like before, simply run: >
+
+        :DiffviewFileHistory %

+
+The plugin will from here on out require `plenary.nvim`:
+https://github.com/nvim-lua/plenary.nvim
+
+I'm using plenary for it's async utilities as well as job management. To
+update, just make sure plenary is loaded before diffview. Examples:
+
+        Packer:~
+            `use { 'sindrets/diffview.nvim', requires = 'nvim-lua/plenary.nvim' }`
+
+        Plug:~

+            `Plug 'sindrets/diffview.nvim'`

+
+PR: https://github.com/sindrets/diffview.nvim/pull/64
+
+This PR introduces some small breaking changes in the config, and for plugins
+integrating diffview.nvim.
+
+The `use_icons` config table key has been moved out of the `file_panel` table.
+This has been done because `use_icons` now applies to other contexts than just
+the file panel. The correct way to configure this now is to set `use_icons`
+somewhere from the top level of the config table.
+
+For plugins integrating diffview.nvim:
+Several of the git utilities have been refactored into their own namespace
+(`lua/diffview/git/`). I (STS) felt this was necessary due to the growing
+scope of the plugin. Most notably this means that the `Rev` class now resides
+in `lua/diffview/git/rev.lua`.

+          ## Test with a `minimal.lua` file
+          I know the temptation is to skip this step but please don't. With the quantity of plugins you have in your Neovim config, it's like searching for a needle in a haystack.
+
+          Firstly, test and run Neovim with the minimal config below. Be sure to add your Persisted.nvim config, saving to a `minimal.lua` file and adding any additional plugins you may need.
+          ```lua
+          local root = "/tmp/persisted"
+
+          -- Set stdpaths to use root dir
+          for _, name in ipairs({ "config", "data", "state", "cache" }) do
+            vim.env[("XDG_%s_HOME"):format(name:upper())] = root .. "/" .. name
+          end
+
+          -- Bootstrap lazy
+          local lazypath = root .. "/plugins/lazy.nvim"
+          if not vim.loop.fs_stat(lazypath) then
+            vim.fn.system({
+              "git",
+              "clone",
+              "--filter=blob:none",
+              "--single-branch",
+              "https://github.com/folke/lazy.nvim.git",
+              lazypath,
+            })
+          end
+          vim.opt.runtimepath:prepend(lazypath)
+
+          vim.opt.sessionoptions = "buffers,curdir,folds,globals,tabpages,winpos,winsize" -- Session options to store in the session
+
+          -- Install plugins
+          local plugins = {
+            {
+              "olimorris/persisted.nvim",
+              opts = {
+                -- Your custom config here
+              }
+            },
+            -- Put any other plugins here
+          }
+          require("lazy").setup(plugins, {
+            root = root .. "/plugins",
+          })
+          ```
+
+          Once you've updated for your config, run Neovim with this command:
+          ```sh
+          nvim --clean -u minimal.lua
+          ```
+
+          Open some buffers and save the session with:
+          ```sh
+          :SessionSave
+          ```
+
+          Then re-open neovim and load the session with:
+          ```sh
+          :SessionLoad

+# Contributing
+
+If you open a PR please consider the following:
+
+- If you're adding new functionality, please open an issue to discuss the design of the new feature
+- How the end user will consume your new feature. It's often easier to start with the API and work backwards
+- Consider the use of [conventional commits](https://www.conventionalcommits.org/en/v1.0.0/) to make your commit messages more descriptive
+- Add new tests to the plugin (use the existing ones as a template)
+
+The mantra for this plugin is "simple session management" and as such the code base is relatively simple. Please consider this in your code.

+<b>Persisted.nvim</b> is a simple lua plugin for working with sessions in Neovim<br>
+(Forked from <a href="https://github.com/folke/persistence.nvim">Persistence.nvim</a>)
+</p>
+
+<!-- panvimdoc-ignore-end -->
+
+## :sparkles: Features
+
+- :evergreen_tree: Supports sessions across multiple git branches
+- :telescope: Telescope extension to work with saved sessions
+- :tickets: Custom events which users can hook into for tighter integration
+- :memo: Simple API to save/stop/restore/delete/list the current session(s)
+- :open_file_folder: Supports autosaving and autoloading of sessions with allowed/ignored directories
+- :floppy_disk: Automatically saves the active session under `.local/share/nvim/sessions` on exiting Neovim
+
+## :zap: Requirements
+
+- Neovim >= 0.8.0
+
+## :package: Installation
+
+Install the plugin with your preferred package manager:
+
+**[Lazy.nvim](https://github.com/folke/lazy.nvim)**
+
+```lua
+-- Lua
+{
+  "olimorris/persisted.nvim",
+  lazy = false, -- make sure the plugin is always loaded at startup
+  config = true
+}
+```
+
+> [!NOTE]
+> Setting `lazy = true` option may be useful if you use a dashboard
+
+**[Packer](https://github.com/wbthomason/packer.nvim)**
+
+```lua
+-- Lua
+use({
+  "olimorris/persisted.nvim",
+  config = function()
+    require("persisted").setup()
+  end,
+})
+```
+
+**[Vim Plug](https://github.com/junegunn/vim-plug)**
+
+```vim
+" Vim Script
+Plug 'olimorris/persisted.nvim'
+
+lua << EOF
+  require("persisted").setup {
+    -- your configuration comes here
+    -- or leave it empty to use the default settings
+    -- refer to the configuration section below
+  }
+EOF
+```
+
+If you wish to use session _autoloading_ alongside a dashboard plugin, it is recommended that you give this plugin a greater loading priority. With **Packer** the `after` config option can be used and in **Lazy.nvim**, the `priority` property.
+
+### Telescope extension
+
+Ensure that the telescope extension is loaded with:
+
+```lua
+require("telescope").load_extension("persisted")
+```
+
+The layout can then be customised from within Telescope:
+
+```lua
+require('telescope').setup({
+  defaults = {
+    …
+  },
+  extensions = {
+    persisted = {
+      layout_config = { width = 0.55, height = 0.55 }
+    }
+  }
+})
+```
+
+## :rocket: Usage
+
+### Commands
+
+The plugin comes with a number of commands:
+
+- `:SessionToggle` - Determines whether to load, start or stop a session
+- `:SessionStart` - Start recording a session. Useful if `autosave = false`
+- `:SessionStop` - Stop recording a session
+- `:SessionSave` - Save the current session
+- `:SessionLoad` - Load the session for the current directory and current branch (if `git_use_branch = true`)
+- `:SessionLoadLast` - Load the most recent session
+- `:SessionLoadFromFile` - Load a session from a given path
+- `:SessionDelete` - Delete the current session
+
+### Telescope extension
+
+<!-- panvimdoc-ignore-start -->
+
+<p align="center">
+<img src="https://github.com/olimorris/persisted.nvim/assets/9512444/5bfd6f94-ff70-4f2b-9193-53cdf7140d75" alt="Telescope">
+</p>
+
+<!-- panvimdoc-ignore-end -->
+
+The Telescope extension may be opened via `:Telescope persisted`. The available actions are:
+
+- `<CR>` - Open/source the session file
+- `<C-b>` - Add/update the git branch for the session file
+- `<C-c>` - Copy the session file
+- `<C-d>` - Delete the session file
+
+### Global variables
+
+The plugin sets a number of global variables throughout its lifecycle:
+
+- `vim.g.persisting` - (bool) Determines if the plugin is active for the current session
+- `vim.g.persisted_exists` - (bool) Determines if a session exists for the current working directory
+- `vim.g.persisted_loaded_session` - (string) The file path to the current session
+
+## :wrench: Configuration
+
+### Defaults
+
+The plugin comes with the following defaults:
+
+```lua
+require("persisted").setup({
+  save_dir = vim.fn.expand(vim.fn.stdpath("data") .. "/sessions/"), -- directory where session files are saved
+  silent = false, -- silent nvim message when sourcing session file
+  use_git_branch = false, -- create session files based on the branch of a git enabled repository
+  default_branch = "main", -- the branch to load if a session file is not found for the current branch
+  autosave = true, -- automatically save session files when exiting Neovim
+  should_autosave = nil, -- function to determine if a session should be autosaved
+  autoload = false, -- automatically load the session for the cwd on Neovim startup
+  on_autoload_no_session = nil, -- function to run when `autoload = true` but there is no session to load
+  follow_cwd = true, -- change session file name to match current working directory if it changes
+  allowed_dirs = nil, -- table of dirs that the plugin will auto-save and auto-load from
+  ignored_dirs = nil, -- table of dirs that are ignored when auto-saving and auto-loading
+  ignored_branches = nil, -- table of branch patterns that are ignored for auto-saving and auto-loading
+  telescope = {
+    reset_prompt = true, -- Reset the Telescope prompt after an action?
+    mappings = { -- table of mappings for the Telescope extension
+      change_branch = "<c-b>",
+      copy_session = "<c-c>",
+      delete_session = "<c-d>",
+    },
+    icons = { -- icons displayed in the picker, set to nil to disable entirely
+      branch = " ",
+      dir = " ",
+      selected = " ",
+    },
+  },
+})
+```
+
+### What is saved in the session?
+
+As the plugin uses Vim's `:mksession` command then you may change the `vim.o.sessionoptions` value to determine what to write into the session. Please see `:h sessionoptions` for more information.
+
+> [!NOTE]
+> The author uses: `vim.o.sessionoptions = "buffers,curdir,folds,tabpages,winpos,winsize"`
+
+### Session save location
+
+The location of the session files may be changed by altering the `save_dir` configuration option. For example:
+
+```lua
+require("persisted").setup({
+  save_dir = vim.fn.expand(vim.fn.stdpath("data") .. "/sessions/"), -- Resolves to ~/.local/share/nvim/sessions/
+})
+```
+
+> [!NOTE]
+> The plugin may be unable to find existing sessions if the `save_dir` value is changed
+
+### Git branching
+
+One of the plugin's core features is the ability to have multiple session files for a given project, by using git branches. To enable git branching:
+
+```lua
+require("persisted").setup({
+  use_git_branch = true,
+})
+```
+
+### Autosaving
+
+By default, the plugin will automatically save a Neovim session to disk when the `VimLeavePre` event is triggered. Autosaving can be turned off by:
+
+```lua
+require("persisted").setup({
+  autosave = false,
+})
+```
+
+Autosaving can be further controlled for certain directories by specifying `allowed_dirs` and `ignored_dirs`.
+
+There may be occasions when you do not wish to autosave; perhaps when a dashboard or a certain buftype is present. To control this, a callback function, `should_autosave`, may be used which should return a boolean value.
+
+```lua
+require("persisted").setup({
+  should_autosave = function()
+    -- do not autosave if the alpha dashboard is the current filetype
+    if vim.bo.filetype == "alpha" then
+      return false
+    end
+    return true
+  end,
+})
+```
+
+Of course, if you wish to manually save the session when autosaving is disabled, the `:SessionSave` command can be used.
+
+> [!NOTE]
+> If `autosave = false` then the `should_autosave` callback will not be executed.
+
+### Autoloading
+
+The plugin can be enabled to automatically load sessions when Neovim is started. Whilst off by default, this can be turned on by:
+
+```lua
+require("persisted").setup({
+  autoload = true,
+})
+```
+
+You can also provide a function to run when `autoload = true` but there is no session to be loaded:
+
+```lua
+require("persisted").setup({
+  autoload = true,
+  on_autoload_no_session = function()
+    vim.notify("No existing session to load.")
+  end
+})
+```
+
+Autoloading can be further controlled for certain directories by specifying `allowed_dirs` and `ignored_dirs`.
+
+> [!NOTE]
+> Autoloading will not occur if the plugin is lazy loaded or a user opens Neovim with arguments other than a single directory argument. For example: `nvim some_file.rb` will not result in autoloading but `nvim some/existing/path` or `nvim .` will.
+
+### Following current working directory
+
+There may be a need to change the working directory to quickly access files in other directories without changing the current session's name on save. This behavior can be configured with `follow_cwd = false`.
+
+By default, the session name will match the current working directory:
+
+```lua
+require("persisted").setup({
+  follow_cwd = true,
+})
+```
+
+> [!NOTE]
+> If `follow_cwd = false` the session name is stored upon loading under the global variable `vim.g.persisting_session`. This variable can be manually adjusted if changes to the session name are needed. Alternatively, if `follow_cwd = true` then `vim.g.persisting_session = nil`.
+
+### Allowed directories
+
+You may specify a table of directories for which the plugin will autosave and/or autoload from. For example:
+
+```lua
+require("persisted").setup({
+  allowed_dirs = {
+    "~/.dotfiles",
+    "~/Code",
+  },
+})
+```
+
+Specifying `~/Code` will autosave and autoload from that directory as well as all its sub-directories.
+
+> [!NOTE]
+> If `allowed_dirs` is left at its default value and `autosave` and/or `autoload` are set to `true`, then the plugin will autoload/autosave from _any_ directory
+
+### Ignored directories
+
+You may specify a table of directories for which the plugin will **never** autosave and autoload from. For example:
+
+```lua
+require("persisted").setup({
+  ignored_dirs = {
+    "~/.config",
+    "~/.local/nvim"
+  },
+})
+```
+
+Specifying `~/.config` will prevent any autosaving and autoloading from that directory as well as all its sub-directories.
+
+You can also specify exact directory matches to ignore. In this case, unlike the default behavior which ignores all children of the ignored directory, this will ignore only the specified child. For example:
+
+```lua
+require("persisted").setup({
+  ignored_dirs = {
+    "~/.config",
+    "~/.local/nvim",
+    { "/", exact = true },
+    { "/tmp", exact = true }
+  },
+})
+```
+
+In this setup, `~/.config` and `~/.local/nvim` are still going to behave in their default setting (ignoring all listed directory and its children), however `/` and `/tmp` will only ignore those directories exactly.
+
+### Ignored branches
+
+You may specify a table of patterns that match against branches for which the plugin will **never** autosave and autoload from:
+
+```lua
+require("persisted").setup({
+  ignored_branches = {
+    "^master",
+    "feature/%u"
+  },
+})
+```
+
+### Events / Callbacks
+
+The plugin fires events at various points during its lifecycle:
+
+- `PersistedLoadPre` - For _before_ a session is loaded
+- `PersistedLoadPost` - For _after_ a session is loaded
+- `PersistedTelescopeLoadPre` - For _before_ a session is loaded via Telescope
+- `PersistedTelescopeLoadPost` - For _after_ a session is loaded via Telescope
+- `PersistedSavePre` - For _before_ a session is saved
+- `PersistedSavePost` - For _after_ a session is saved
+- `PersistedDeletePre` - For _before_ a session is deleted
+- `PersistedDeletePost` - For _after_ a session is deleted
+- `PersistedStateChange` - For when a session is _started_ or _stopped_
+- `PersistedToggled` - For when a session is toggled
+
+These events can be consumed anywhere within your configuration by utilising the `vim.api.nvim_create_autocmd` function.
+
+#### Example use case
+
+A commonly requested example is to use the Telescope extension to load a session, saving the current session before clearing all of the open buffers:
+
+```lua
+local group = vim.api.nvim_create_augroup("PersistedHooks", {})
+
+vim.api.nvim_create_autocmd({ "User" }, {
+  pattern = "PersistedTelescopeLoadPre",
+  group = group,
+  callback = function(session)
+    -- Save the currently loaded session using a global variable
+    require("persisted").save({ session = vim.g.persisted_loaded_session })
+
+    -- Delete all of the open buffers
+    vim.api.nvim_input("<ESC>:%bd!<CR>")
+  end,
+})
+```
+
+#### Using callback data
+
+When certain events are fired, session data is made available for the user to consume, for example:
+
+```lua
+{
+  branch = "main",
+  dir_path = "Code/Neovim/persisted.nvim",
+  file_path = "/Users/Oli/.local/share/nvim/sessions/%Users%Oli%Code%Neovim%persisted.nvim@@main.vim",
+  name = "Code/Neovim/persisted.nvim@@main",
+}
+```
+
+To consume this data, use the `session.data` table in your autocmd:
+
+```lua
+vim.api.nvim_create_autocmd({ "User" }, {
+  pattern = "PersistedLoadPost",
+  group = group,
+  callback = function(session)
+    print(session.data.branch)
+  end,
+})
+```
+
+> [!NOTE]
+> This data is available for the `PersistedLoad`, `PersistedDelete` and `PersistedTelescope` events

+CONFIGURATION                                   *persisted.nvim-configuration*
+
+
+DEFAULTS ~
+
+The plugin comes with the following defaults:
+
+>lua
+    require("persisted").setup({
+      save_dir = vim.fn.expand(vim.fn.stdpath("data") .. "/sessions/"), -- directory where session files are saved

+          dir = " ",
+          selected = " ",
+        },
+      },
+    })
+<
+
+
+WHAT IS SAVED IN THE SESSION? ~
+
+As the plugin uses Vim’s `:mksession` command then you may change the
+`vim.o.sessionoptions` value to determine what to write into the session.
+Please see `:h sessionoptions` for more information.
+
+
+  [!NOTE] The author uses: `vim.o.sessionoptions =
+  "buffers,curdir,folds,tabpages,winpos,winsize"`
+
+SESSION SAVE LOCATION ~
+
+The location of the session files may be changed by altering the `save_dir`
+configuration option. For example:
+
+>lua
+    require("persisted").setup({
+      save_dir = vim.fn.expand(vim.fn.stdpath("data") .. "/sessions/"), -- Resolves to ~/.local/share/nvim/sessions/
+    })
+<
+
+
+  [!NOTE] The plugin may be unable to find existing sessions if the `save_dir`
+  value is changed
+
+GIT BRANCHING ~
+
+One of the plugin’s core features is the ability to have multiple session
+files for a given project, by using git branches. To enable git branching:
+
+>lua
+    require("persisted").setup({
+      use_git_branch = true,
+    })
+<
+
+
+AUTOSAVING ~
+
+By default, the plugin will automatically save a Neovim session to disk when
+the `VimLeavePre` event is triggered. Autosaving can be turned off by:
+
+>lua
+    require("persisted").setup({
+      autosave = false,
+    })
+<
+
+Autosaving can be further controlled for certain directories by specifying
+`allowed_dirs` and `ignored_dirs`.
+
+There may be occasions when you do not wish to autosave; perhaps when a
+dashboard or a certain buftype is present. To control this, a callback
+function, `should_autosave`, may be used which should return a boolean value.
+
+>lua
+    require("persisted").setup({
+      should_autosave = function()
+        -- do not autosave if the alpha dashboard is the current filetype
+        if vim.bo.filetype == "alpha" then
+          return false
+        end
+        return true
+      end,
+    })
+<
+
+Of course, if you wish to manually save the session when autosaving is
+disabled, the `:SessionSave` command can be used.
+
+
+  [!NOTE] If `autosave = false` then the `should_autosave` callback will not be
+  executed.
+
+AUTOLOADING ~
+
+The plugin can be enabled to automatically load sessions when Neovim is
+started. Whilst off by default, this can be turned on by:
+
+>lua
+    require("persisted").setup({
+      autoload = true,
+    })
+<
+
+You can also provide a function to run when `autoload = true` but there is no
+session to be loaded:
+
+>lua
+    require("persisted").setup({
+      autoload = true,
+      on_autoload_no_session = function()
+        vim.notify("No existing session to load.")
+      end
+    })
+<
+
+Autoloading can be further controlled for certain directories by specifying
+`allowed_dirs` and `ignored_dirs`.
+
+
+  [!NOTE] Autoloading will not occur if the plugin is lazy loaded or a user opens
+  Neovim with arguments other than a single directory argument. For example:
+  `nvim some_file.rb` will not result in autoloading but `nvim
+  some/existing/path` or `nvim .` will.
+
+FOLLOWING CURRENT WORKING DIRECTORY ~
+
+There may be a need to change the working directory to quickly access files in
+other directories without changing the current session’s name on save. This
+behavior can be configured with `follow_cwd = false`.
+
+By default, the session name will match the current working directory:
+
+>lua
+    require("persisted").setup({
+      follow_cwd = true,
+    })
+<
+
+
+  [!NOTE] If `follow_cwd = false` the session name is stored upon loading under
+  the global variable `vim.g.persisting_session`. This variable can be manually
+  adjusted if changes to the session name are needed. Alternatively, if
+  `follow_cwd = true` then `vim.g.persisting_session = nil`.
+
+ALLOWED DIRECTORIES ~
+
+You may specify a table of directories for which the plugin will autosave
+and/or autoload from. For example:
+
+>lua
+    require("persisted").setup({
+      allowed_dirs = {
+        "~/.dotfiles",
+        "~/Code",
+      },
+    })
+<
+
+Specifying `~/Code` will autosave and autoload from that directory as well as
+all its sub-directories.
+
+
+  [!NOTE] If `allowed_dirs` is left at its default value and `autosave` and/or
+  `autoload` are set to `true`, then the plugin will autoload/autosave from _any_
+  directory
+
+IGNORED DIRECTORIES ~
+
+You may specify a table of directories for which the plugin will **never**
+autosave and autoload from. For example:
+
+>lua
+    require("persisted").setup({
+      ignored_dirs = {
+        "~/.config",
+        "~/.local/nvim"
+      },
+    })
+<
+
+Specifying `~/.config` will prevent any autosaving and autoloading from that
+directory as well as all its sub-directories.
+
+You can also specify exact directory matches to ignore. In this case, unlike
+the default behavior which ignores all children of the ignored directory, this
+will ignore only the specified child. For example:
+
+>lua
+    require("persisted").setup({
+      ignored_dirs = {
+        "~/.config",
+        "~/.local/nvim",
+        { "/", exact = true },
+        { "/tmp", exact = true }
+      },
+    })
+<
+
+In this setup, `~/.config` and `~/.local/nvim` are still going to behave in
+their default setting (ignoring all listed directory and its children), however
+`/` and `/tmp` will only ignore those directories exactly.
+
+
+IGNORED BRANCHES ~
+
+You may specify a table of patterns that match against branches for which the
+plugin will **never** autosave and autoload from:
+
+>lua
+    require("persisted").setup({
+      ignored_branches = {
+        "^master",
+        "feature/%u"
+      },
+    })
+<
+
+
+EVENTS / CALLBACKS ~
+
+The plugin fires events at various points during its lifecycle:
+
+
+- `PersistedLoadPre` - For _before_ a session is loaded
+- `PersistedLoadPost` - For _after_ a session is loaded
+- `PersistedTelescopeLoadPre` - For _before_ a session is loaded via Telescope
+- `PersistedTelescopeLoadPost` - For _after_ a session is loaded via Telescope
+- `PersistedSavePre` - For _before_ a session is saved
+- `PersistedSavePost` - For _after_ a session is saved
+- `PersistedDeletePre` - For _before_ a session is deleted
+- `PersistedDeletePost` - For _after_ a session is deleted
+- `PersistedStateChange` - For when a session is _started_ or _stopped_
+- `PersistedToggled` - For when a session is toggled
+
+These events can be consumed anywhere within your configuration by utilising
+the `vim.api.nvim_create_autocmd` function.
+
+
+EXAMPLE USE CASE
+
+A commonly requested example is to use the Telescope extension to load a
+session, saving the current session before clearing all of the open buffers:
+
+>lua
+    local group = vim.api.nvim_create_augroup("PersistedHooks", {})
+    
+    vim.api.nvim_create_autocmd({ "User" }, {
+      pattern = "PersistedTelescopeLoadPre",
+      group = group,
+      callback = function(session)
+        -- Save the currently loaded session using a global variable
+        require("persisted").save({ session = vim.g.persisted_loaded_session })
+    
+        -- Delete all of the open buffers
+        vim.api.nvim_input("<ESC>:%bd!<CR>")
+      end,
+    })
+<
+
+
+USING CALLBACK DATA
+
+When certain events are fired, session data is made available for the user to
+consume, for example:
+
+>lua
+    {
+      branch = "main",
+      dir_path = "Code/Neovim/persisted.nvim",
+      file_path = "/Users/Oli/.local/share/nvim/sessions/%Users%Oli%Code%Neovim%persisted.nvim@@main.vim",
+      name = "Code/Neovim/persisted.nvim@@main",
+    }
+<
+
+To consume this data, use the `session.data` table in your autocmd:
+
+>lua
+    vim.api.nvim_create_autocmd({ "User" }, {
+      pattern = "PersistedLoadPost",
+      group = group,
+      callback = function(session)
+        print(session.data.branch)
+      end,
+    })
+<
+
+
+  [!NOTE] This data is available for the `PersistedLoad`, `PersistedDelete` and
+  `PersistedTelescope` events

+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes

+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,

+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,

+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS

+# 🗃️ project.nvim
+
+**project.nvim** is an all in one neovim plugin written in lua that provides
+superior project management.
+
+![Telescope Integration](https://user-images.githubusercontent.com/36672196/129409509-62340f10-4dd0-4c1a-9252-8bfedf2a9945.png)
+
+## ⚡ Requirements
+
+- Neovim >= 0.5.0
+
+## ✨ Features
+
+- Automagically cd to project directory using nvim lsp
+  - Dependency free, does not rely on lspconfig
+- If no lsp then uses pattern matching to cd to root directory
+- Telescope integration `:Telescope projects`
+  - Access your recently opened projects from telescope!
+  - Asynchronous file io so it will not slow down vim when reading the history
+    file on startup.
+- ~~Nvim-tree.lua support/integration~~
+  - Please add the following to your config instead:
+    ```vim
+    " Vim Script
+    lua << EOF
+    require("nvim-tree").setup({
+      sync_root_with_cwd = true,
+      respect_buf_cwd = true,

+      sync_root_with_cwd = true,
+      respect_buf_cwd = true,

+
+## 📦 Installation
+
+Install the plugin with your preferred package manager:
+
+### [vim-plug](https://github.com/junegunn/vim-plug)
+
+```vim
+" Vim Script
+Plug 'ahmedkhalf/project.nvim'
+
+lua << EOF
+  require("project_nvim").setup {
+    -- your configuration comes here
+    -- or leave it empty to use the default settings
+    -- refer to the configuration section below
+  }
+EOF
+```
+
+### [packer](https://github.com/wbthomason/packer.nvim)
+
+```lua
+-- Lua
+use {
+  "ahmedkhalf/project.nvim",
+  config = function()
+    require("project_nvim").setup {
+      -- your configuration comes here
+      -- or leave it empty to use the default settings
+      -- refer to the configuration section below
+    }
+  end
+}
+```
+
+## ⚙️ Configuration
+
+**project.nvim** comes with the following defaults:
+
+```lua
+{
+  -- Manual mode doesn't automatically change your root directory, so you have
+  -- the option to manually do so using `:ProjectRoot` command.
+  manual_mode = false,
+
+  -- Methods of detecting the root directory. **"lsp"** uses the native neovim
+  -- lsp, while **"pattern"** uses vim-rooter like glob pattern matching. Here
+  -- order matters: if one is not detected, the other is used as fallback. You
+  -- can also delete or rearangne the detection methods.
+  detection_methods = { "lsp", "pattern" },
+
+  -- All the patterns used to detect root dir, when **"pattern"** is in
+  -- detection_methods
+  patterns = { ".git", "_darcs", ".hg", ".bzr", ".svn", "Makefile", "package.json" },
+
+  -- Table of lsp clients to ignore by name
+  -- eg: { "efm", ... }
+  ignore_lsp = {},
+
+  -- Don't calculate root dir on specific directories
+  -- Ex: { "~/.cargo/*", ... }
+  exclude_dirs = {},
+
+  -- Show hidden files in telescope
+  show_hidden = false,
+
+  -- When set to false, you will get a message when project.nvim changes your
+  -- directory.
+  silent_chdir = true,
+
+  -- What scope to change the directory, valid options are
+  -- * global (default)
+  -- * tab
+  -- * win
+  scope_chdir = 'global',
+
+  -- Path where project.nvim will store the project history for use in
+  -- telescope
+  datapath = vim.fn.stdpath("data"),
+}
+```
+
+Even if you are pleased with the defaults, please note that `setup {}` must be
+called for the plugin to start.
+
+### Pattern Matching
+
+**project.nvim**'s pattern engine uses the same expressions as vim-rooter, but
+for your convenience, I will copy paste them here:
+
+To specify the root is a certain directory, prefix it with `=`.
+
+```lua
+patterns = { "=src" }
+```
+
+To specify the root has a certain directory or file (which may be a glob), just
+give the name:
+
+```lua
+patterns = { ".git", "Makefile", "*.sln", "build/env.sh" }
+```
+
+To specify the root has a certain directory as an ancestor (useful for
+excluding directories), prefix it with `^`:
+
+```lua
+patterns = { "^fixtures" }
+```
+
+To specify the root has a certain directory as its direct ancestor / parent
+(useful when you put working projects in a common directory), prefix it with
+`>`:
+
+```lua
+patterns = { ">Latex" }
+```
+
+To exclude a pattern, prefix it with `!`.
+
+```lua
+patterns = { "!.git/worktrees", "!=extras", "!^fixtures", "!build/env.sh" }
+```
+
+List your exclusions before the patterns you do want.
+
+### Telescope Integration
+
+To enable telescope integration:
+```lua
+require('telescope').load_extension('projects')
+```
+
+#### Telescope Projects Picker
+To use the projects picker
+```lua
+require'telescope'.extensions.projects.projects{}
+```
+
+#### Telescope mappings
+
+**project.nvim** comes with the following mappings:
+
+| Normal mode | Insert mode | Action                     |
+| ----------- | ----------- | -------------------------- |
+| f           | \<c-f\>     | find\_project\_files       |
+| b           | \<c-b\>     | browse\_project\_files     |
+| d           | \<c-d\>     | delete\_project            |
+| s           | \<c-s\>     | search\_in\_project\_files |
+| r           | \<c-r\>     | recent\_project\_files     |
+| w           | \<c-w\>     | change\_working\_directory |
+
+## API
+
+Get a list of recent projects:
+
+```lua
+local project_nvim = require("project_nvim")
+local recent_projects = project_nvim.get_recent_projects()
+
+print(vim.inspect(recent_projects))
+```

+
+## Branch model
+
+VimTeX is developed mainly through the master branch, and pull requests should
+be [fork based](https://help.github.com/articles/using-pull-requests/).
+
+## Documentation style
+
+Vim help files have their own specific syntax. There is a Vim help section on
+how to write them, see [`:h help-writing`](http://vimdoc.sourceforge.net/htmldoc/helphelp.html#help-writing).
+
+The VimTeX documentation style should be relatively clear, and it should be
+easy to see from the existing documentation how to write it. Still, here are
+some pointers:
+
+- Max 80 columns per line
+- Use the help tag system for pointers to other parts of the Vim documentation
+- Use line of `=`s to separate sections
+- Use line of `-`s to separate subsections
+- The section tags should be right aligned at the 79th column
+- Sections should be included and linked to from the table of contents
+
+VimTeX also has a high level code [documentation](./DOCUMENTATION.md) mainly
+for developers. It should provide an overview of the VimTeX code and APIs and
+may help developers (and users) to understand the functionalities of the
+plugin a little bit faster.
+
+## Code style
+
+When submitting code for VimTeX, please adhere to the following standards:
+
+- Use `shiftwidth=2` - no tabs!
+- Write readable code
+  - Break lines for readability
+    - Line should not be longer than 80 columns
+  - Use comments:
+    - For complex code that is difficult to understand
+    - Simple code does not need comments
+  - Use (single) empty lines to separate logical blocks of code
+  - Use good variable names
+    - The name should indicate what the variable is/does
+    - Variable names should be lower case
+    - Local function variables should be preceded with `l:`
+  - Prefer single quoted strings
+  - See also the [Google vimscript style
+    guide](https://google.github.io/styleguide/vimscriptguide.xml)
+- Use markers for folding
+  - I generally only fold functions, and I tend to group similar functions so
+    that when folded, I get a nice structural overview of a file
+  - See some of the files for examples of how I do this
+
+## Running tests
+
+New functionality should be accompanied by tests. Tests can be run from the
+`test` folder with `make`. The tests currently only run on Linux, and the
+following utilities are required to run all the tests:
+
+- `wget`
+- `chronic` (from [moreutils](https://joeyh.name/code/moreutils/))
+
+These utilities may not come with all Linux distributions and may need to be
+installed with your favorite package manager (e.g. `yum`, `apt-get`, or `brew`
+on Mac).
+
+By default, the tests are run with the Neovim executable `nvim`. You can change
+the executable by setting the environment variable `MYVIM` before running. To
+run with vanilla vim, use `MYVIM="vim -T dumb --not-a-term --noplugin -n"`.
+Either export this in your shell, or prepend to `make`, that is, run
+`MYVIM="vim -T dumb --not-a-term --noplugin -n" make`.

+# Documentation
+
+Welcome to the "high-level documentation" of VimTeX. The goal of this document
+is to help developers (and curious users) to understand the structure of the
+plugin and how it works. That is, it should essentially provide a useful and
+quick overview of the most important files and directories. See also `:help
+vimtex-code` for some related information.
+
+The table of contents has the same structure as the essential file structure of
+VimTeX. E.g., if you want to know something about
+`vimtex/autoload/vimtex/somefile.vim`, then you can lookup the path in the
+table of contents and click on it.

+
+# ftplugin
+The main features of VimTeX are implemented as a filetype plugin for Vim and
+neovim. This is a specific concept that you can read about with `:help
+filetype-plugins`.
+
+VimTeX provides a filetype plugin for the `tex` and `bib` filetypes. These
+scripts are the main entry points for the bulk functionalities of VimTeX. They
+are both very simple: they ensure that the user wants to load VimTeX, then they
+execute the function `vimtex#init()` from [`autoload/vimtex.vim`](#vimtexvim).
+
+# syntax
+VimTeX is also a syntax plugin and provides a `tex` syntax plugin script. The
+relevant Vim and neovim docs for this is `:help :syn-files`. Essentially, this
+is the entry point for loading the syntax highlighting.
+
+# indent
+VimTeX also has an indentation script; this feature is also a special concept
+with an entry point under the `indent/` directory, see `:help
+indent-expression`. The main purpose of `indent/tex.vim` and `indent/bib.vim`
+is to provide functions like `VimtexIndent()` that are used with the
+`:help 'indentexpr'` option.
+
+# after/ftplugin
+The `after/` directory is a simple Vim and neovim concept that allows to ensure
+that some scripts are loaded _after_ the main scripts. For details of the
+concept, see `:help after-directory`.
+
+Currently, there's only one script `after/ftplugin/tex.vim`. This is used to
+make sure that VimTeX loaded successfully and that there're no conflicts with
+other plugins such as LaTeX-Box.
+
+# autoload
+The `autoload` directory is an important concept in Vimscript. It allows to
+avoid loading code until it is strictly necessary. This allows to substantially
+speed up the initialization phase, since the bulk VimTeX code is not sourced
+unless necessary. See `:help autoload` for more details. It may also be
+instructive to read [this
+chapter](https://learnvimscriptthehardway.stevelosh.com/chapters/42.html) of
+the well known [Learn Vimscript the Hard
+Way](https://learnvimscriptthehardway.stevelosh.com/chapters/42.html) by Steve
+Losh.
+
+## vimtex.vim
+This file defines the main entry point `vimtex#init()`, which is responsible
+for loading all of the VimTeX functionalities, except:
+
+* syntax highlighting is loaded from `syntax/tex.vim`
+* indentation is loaded from `indent/tex.vim`
+
+The main initialization function calls `vimtex#mymodule#init_buffer()` for each
+submodule, if it exists. This function should take care of defining buffer
+local mappings, commands, and autocommands for the respective submodule.
+
+The initialization function also ensures that the current buffer is coupled with
+a corresponding state dictionary, see [autoload/vimtex/state.vim](#statevim).
+
+## vimtex
+This directory holds the bulk of the VimTeX source code. Each `.vim` file
+represents a separate submodule that may provide one or more of the following:
+
+* a functional API that is used in other parts of VimTeX
+* buffer functionalities (mappings, commands, and/or autocommands)
+* state data
+
+### state.vim
+The VimTeX state variable is a dictionary that contains data specific to
+a single LaTeX project. A project may consist of several buffers for different
+files, e.g. if the project is a multi-file project (see `:help
+vimtex-multi-file`). A submodule may add to the state during initialization
+with `vimtex#mymodule#init_state(state)`, which takes the state object as
+a single argument.
+
+### delim.vim
+This file defines an API and some buffer mappings for detecting and
+manipulating the surrounding delimiters.
+
+The API is mostly based on the function `vimtex#delim#get_surrounding(type)`.
+The following is a simple example to detect the surrounding environment. Let
+`|` denote the cursor position:
+
+```tex
+\begin{Environment}
+  Some awesome | text
+\end{Environment}
+```
+
+Example code for working with the environment delimiter:
+
+```vim
+" The return values are dictionaries
+let [l:open, l:close] = vimtex#delim#get_surrounding('env_tex')
+
+" Empty dicts mean we did not find a surrounding environment
+if empty(l:open) | return | endif
+
+" The dicts have several attributes, the most important are probably these:
+echo l:open.name
+echo l:open.lnum
+echo l:open.cnum
+```
+
+### cmd.vim
+This file defines an API and some buffer mappings for detecting and
+manipulating LaTeX commands.
+
+The main API relies on the functions `vimtex#cmd#get_*(...)`, e.g.
+`vimtex#cmd#get_current()`. A simple example usage:
+
+```vim
+let l:cmd = vimtex#cmd#get_current()
+if empty(l:cmd) | return | endif
+
+echo l:cmd.name
+echo l:cmd.pos_start
+echo l:cmd.pos_end
+echo l:cmd.args
+echo l:cmd.opts
+```
+
+### cache.vim
+This file implements an API for creating and accessing caches that can be both
+volatile and persistent, as well as project and buffer local.
+
+Here's an example of how to use a cache.
+
+```vim
+function VimTeXCacheExample()
+  " create a new cache (if the name doesn't exist yet)
+  " with an attribute 'number'. So the cache would be like that:
+  "
+  "   let l:test = {
+  "   'number' = 10,
+  "   }
+  let l:my_cache = vimtex#cache#open('cache_name', {'number' : 10})
+
+  " change the value in you cache
+  let l:my_cache['number'] = 9001
+
+  " will print '9001'
+  echo l:my_cache['number']
+
+  " save your changes
+  " In general it'll be saved in your `$XDG_CACHE_HOME/vimtex/` directory
+  " (normally '~/.cache/vimtex') in the appropriate tex-file where you accessed
+  " cache file.
+  call vimtex#cache#close('cache_name')
+endfunction
+```
+
+### compiler.vim
+This submodule defines an API for interacting with LaTeX compiler backends. It
+also defines the main compiler mappings and commands (e.g. `:VimtexCompile`).
+
+Each supported backend is defined in separated scripts under
+`vimtex/autoload/vimtex/compiler/*.vim`. These scripts provide
+`vimtex#compiler#mycompiler#init()`, which is used to initialize a particular
+backend - it should return a dictionary object that will be part of the VimTeX
+state.
+
+The main compiler API essentially connects to the specified backend. E.g., if
+one uses the default `latexmk` backend, then the top level
+`vimtex#compiler#start()` function will essentially call the
+`s:compiler_nvim.start_single()` function from
+`vimtex/autolaod/vimtex/compiler/latexmk.vim`.
+
+### debug.vim
+This standalone script defines a convenience function for internal debugging:
+`vimtex#debug#stacktrace()` parses the stacktrace from the `v:throwpoint`
+variable (see `:h v:throwpoint` for more information). If this does not exist,
+then we forcibly create it and remove the top element. You can try this code as
+an example:
+
+```vim
+" Save as test.py
+function! Test() abort
+  try
+    throw "Nasty error message is here :D"
+  catch
+    call vimtex#debug#stacktrace(1)
+  endtry
+endfunction
+```
+
+Now type `:call Test()`, and the quickfix window should pop up with the
+specified error message and the location of the error.
+
+### complete.vim
+This script defines the main completion API: `vimtex#complete#omnifunc(...)`.
+See `:help complete-functions` for details on how omnifunctions work.
+
+The function is relatively advanced and allows different completion mechanisms
+for different contexts.
+
+The `complete/` subdirectory contains simple files that lists keywords defined
+for specific packages or classes. These files are used by the command and
+environment completers.
+
+The `complete/tools` directory includes a large map between LaTeX commands and
+unicode glyphs, like `\alpha -> α` and `\beta -> β`. This is used to enrich the
+keywords lists under `complete/` to add more fancy completion menus.
+
+### context.vim
+This script provides a context menu feature (`:help :VimtexContextMenu`). Each
+script under `autoload/vimtex/context/*.vim` defines a specific context and
+its related actions. See
+[here](https://github.com/lervag/vimtex/pull/1961#issuecomment-795476750) for
+a more detailed description of how this is implemented.
+
+For instance, the context `context/cite.vim` defines a citation context (see
+`:help vimtex-context-citation`).
+
+### fold.vim
+This defines the fold functions for VimTeX. Folding is explained in `:help
+folds`. An example of how a folded document may look like:
+
+![folding example](https://github.com/lervag/vimtex-media/blob/main/img/folding.png)
+
+VimTeX defines a custom fold expression, see `:help fold-expr`. The
+`vimtex#fold#init_state` function will apply folding as per the related
+configuration (see `:help vimtex-folding`).
+
+The fold expression is modularized to allow a relatively high degree of
+customizability. Each type is defined in its separate file, e.g.
+`autoload/vimtex/fold/envs.vim` for folding of environments.
+
+### parser.vim
+A lot of VimTeX functionalities relies on some type of parsing. This module
+defines an API for various parsers, both for TeX files and other filetypes
+(e.g. `aux` and `bib`), as well as some specific types of parser (e.g. `toc`
+for parsing TeX files for a table of contents).
+
+The code for each parser is defined in sub modules, e.g. `parser/bib.vim`.
+
+The `vimcomplete.bst` file is used by `parser/bib.vim` in the
+`s:parse_with_bibtex()` function. It is used to convert a `.bib` file to
+a `.bbl` file with `bibtex` - this is useful because the `.bbl` file generated
+with this `.bst` file is very easy to parse.
+
+### toc.vim
+Specifies a simple API and buffer mappings/commands for creating a convenient
+table of contents (TOC) to navigate and inspect a file (`:h :VimtexTocToggle`
+for more information).
+
+![toc example](https://github.com/lervag/vimtex-media/blob/main/img/toc.png)
+
+### qf.vim
+This submodule defines functions and buffer mappings to parse log files and
+similar and put errors and warnings into the quickfix window (see `:help
+quickfix`). The functions are used e.g. by callbacks from the compilers, if
+supported and enabled, to automatically parse log files and display potential
+errors after compilation.
+
+The files `vimtex/autoload/vimtex/qf/*.vim` define different types of log
+parsers. E.g., `qf/bibtex.vim` is used to parse `.blg` files for BibTeX related
+warnings and errors, and `qf/latexlog.vim` parses `.log` files for LaTeX
+warnings and errors. `qf/pulp.vim` defines an alternative log parser that can
+be used instead of `latexlog.vim`. See also `:help g:vimtex_quickfix_method`.
+
+Here's an example of the quickfix list generated by the `qf/latexlog.vim`
+script:
+
+![quickfix example](https://github.com/lervag/vimtex-media/blob/main/img/quickfix.png)
+
+### syntax.vim
+This script implements some convenience functions for the bulk VimTeX code.
+This may be counter intuitive, so be warned.
+
+The idea is that other parts of VimTeX may rely on the syntax state, e.g. to
+determine if a position is within math mode (`vimtex#syntax#in_mathzone(...)`).
+
+The actual syntax rules are defined in the scripts under `syntax/*.vim`.
+
+### syntax
+This subdirectory contains the main syntax highlighting scripts. The entry
+point for the syntax scripts are, as mentioned previously, the top level
+[`syntax/tex.vim`](#syntax). However, as most of the code, the bulk source is
+defined in the autoloaded functions.
+
+In short: `syntax/core.vim` implements the core syntax rules, whereas the
+scripts under `syntax/p/` define package specific syntax rules.
+
+### text\_obj.vim
+This submodule defines text objects, see `:help text-objects`. Buffer local
+mappings are created during initialization.
+
+The module allows to use different backends, including the popular
+[`targets.vim`](https://github.com/wellle/targets.vim).
+
+### view.vim
+This submodule defines the main view API and buffer mappings/commands. That is,
+mappings and commands to open a PDF viewer for the compiled LaTeX document.
+
+The desired PDF viewer is specified  with `g:vimtex_view_method` variable, and
+the specified viewer is initialized from `view/VIEWER.vim` (e.g.
+`view/zathura.vim`). This does essentially just the following for a given VimTeX
+state:
+
+```vim
+let a:state.viewer = vimtex#view#{g:vimtex_view_method}#new()
+```
+
+That is, if `g:vimtex_view_method` is `zathura`, then this calls
+`vimtex#view#zathura#new()`. The `new()` method should return a dictionary
+object with e.g. a `.view()` method that is used to open a file with the
+specified viewer.
+
+## health/vimtex.vim
+VimTeX hooks into the `health.vim` framework provided by `neovim` (see `:help
+health`). This is a utility framework for performing health checks that may
+help users discover problems with e.g. configuration. VimTeX has a few checks
+for e.g. Vim versions and configuration validation.
+
+Note: This is not relevant for regular Vim.
+
+## unite/sources/vimtex.vim
+This script defines a VimTeX table-of-content source for the
+[unite](https://github.com/Shougo/unite.vim) plugin. See `:help vimtex-unite`
+for more info.
+
+# rplugin/python3/denite/source/vimtex.py
+This script defines a VimTeX table-of-content source for the
+[denite.vim](https://github.com/Shougo/denite.nvim) plugin. See also `:help
+vimtex-denite`.
+
+# test
+This directory is used to, you guessed it, define tests for the VimTeX code.
+The tests are built on top of a Makefile based workflow. The `test/Makefile`
+runs all tests defined in sub directories named `test-...`. It is a fundamental
+requirement that all tests run with `make` from the top level `test` directory
+should pass for VimTeX to be deemed stable and fully functional.
+
+The `test/` directory also contains some simple LaTeX and VimTeX configuration
+examples under `test/example-...`, as well as some issue specific test files
+under `issues/ISSUE-NUMBER`.

+## Requirements
+
+VimTeX requires Vim version 8.2.3995 or Neovim version 0.9.5. The requirements
+were updated in April 2024 after the release of VimTeX 2.15. If you are stuck
+on older versions of Vim or Neovim, then you should not use the most recent
+version of VimTeX, but instead remain at the v2.15 tag.
+
+Some features require external tools. For example, the default compiler backend
+relies on [latexmk](https://www.cantab.net/users/johncollins/latexmk/index.html).
+Users are encouraged to read the requirements section in the
+[documentation](doc/vimtex.txt) (`:h vimtex-requirements`).
+
+## Installation
+
+There are a lot of methods for installing plugins.
+The following explains the most common and popular approaches.
+
+**Note**: Many plugin managers provide mechanisms to lazy load plugins. Please
+    don't use this for VimTeX! VimTeX is already lazy loaded by virtue of being
+    a filetype plugin and by using the autoload mechanisms. There is therefore
+    nothing to gain by forcing VimTeX to lazily load through the plugin
+    manager. In fact, doing it will _break_ the inverse-search mechanism, which
+    relies on a _global_ command (`:VimtexInverseSearch`).
+
+### lazy.nvim
+
+In Neovim, [lazy.nvim](https://github.com/folke/lazy.nvim) is probably the most popular plugin manger.
+To install VimTeX, add a plugin spec similar to this:
+```lua
+{
+  "lervag/vimtex",
+  lazy = false,     -- we don't want to lazy load VimTeX
+  -- tag = "v2.15", -- uncomment to pin to a specific release
+  init = function()
+    -- VimTeX configuration goes here
+  end
+}
+```
+
+### vim-plug
+
+If you use [vim-plug](https://github.com/junegunn/vim-plug), then add *one* of the following lines to your configuration.
+The first will use the latest versions from the `master` branch, whereas the second will pin to a release tag.
+
+```vim
+Plug 'lervag/vimtex'
+Plug 'lervag/vimtex', { 'tag': 'v2.15' }
+```
+
+### Other
+
+There are many other plugin managers out there.
+They are typically well documented, and it should be straightforward to extrapolate the above snippets.
+
+**Note**: If you use the built-in package feature, then:
+* Make sure to read and understand the package feature: `:help package`!
+* Use the `/pack/foo/start` subdirectory to make sure the filetype plugin is
+  automatically loaded for the `tex` filetypes.
+* Helptags are not generated automatically. Run `:helptags` to generate them.
+* Please note that by default Vim puts custom `/start/` plugin directories at
+  the end of the `&runtimepath`. This means the built in filetype plugin is
+  loaded, which prevents VimTeX from loading. See
+  [#1413](https://github.com/lervag/vimtex/issues/1413) for two suggested
+  solutions to this. To see which scripts are loaded and in which order, use
+  `:scriptnames`.
+* For more information on how to use the Vim native package solution, see
+  [here](https://vi.stackexchange.com/questions/9522/what-is-the-vim8-package-feature-and-how-should-i-use-it)
+  and [here](https://shapeshed.com/vim-packages/).
+
+## Configuration
+
+After installing VimTeX, you should edit your `.vimrc` file or `init.vim` file
+to configure VimTeX to your liking. Users should read the documentation to
+learn the various configuration possibilities, but the below is a simple
+overview of some of the main aspects.
+
+**PLEASE don't just copy this without reading the comments!**
+
+```vim
+" This is necessary for VimTeX to load properly. The "indent" is optional.
+" Note that most plugin managers will do this automatically.
+filetype plugin indent on
+
+" This enables Vim's and neovim's syntax-related features. Without this, some
+" VimTeX features will not work (see ":help vimtex-requirements" for more
+" info).
+syntax enable
+
+" Viewer options: One may configure the viewer either by specifying a built-in
+" viewer method:
+let g:vimtex_view_method = 'zathura'
+
+" Or with a generic interface:
+let g:vimtex_view_general_viewer = 'okular'
+let g:vimtex_view_general_options = '--unique file:@pdf\#src:@line@tex'
+
+" VimTeX uses latexmk as the default compiler backend. If you use it, which is
+" strongly recommended, you probably don't need to configure anything. If you
+" want another compiler backend, you can change it as follows. The list of
+" supported backends and further explanation is provided in the documentation,
+" see ":help vimtex-compiler".
+let g:vimtex_compiler_method = 'latexrun'
+
+" Most VimTeX mappings rely on localleader and this can be changed with the
+" following line. The default is usually fine and is the symbol "\".
+let maplocalleader = ","
+```
+
+**Note**: If the compiler or the viewer doesn't start properly, one may
+  type `<localleader>li` to view the system commands that were executed to
+  start them. To inspect the compiler output, use `<localleader>lo`.
+

+[#1946](https://github.com/lervag/vimtex/issues/1946#issuecomment-846345095)).
+The example LaTeX file used in the video is available under
+[`test/example-quick-start/main.tex`](test/example-quick-start/main.tex) and it

+
+### Tutorial
+
+Both new and experienced users are encouraged to read the excellent guide by
+@ejmastnak: [Getting started with the VimTeX plugin](https://ejmastnak.com/tutorials/vim-latex/vimtex/).
+The guide covers all the fundamentals of setting up a VimTeX-based LaTeX
+workflow, including usage of the VimTeX plugin, compilation, setting up forward
+and inverse search with a PDF reader, and Vimscript tools for user-specific
+customization.
+
+### Documentation
+
+Users are of course _strongly_ encouraged to read the documentation, at least
+the introduction, to learn about the different features and possibilities
+provided by VimTeX (see [`:h vimtex`](doc/vimtex.txt)). Advanced users and
+potential developers may also be interested in reading the supplementary
+documents:
+
+* [CONTRIBUTING.md](CONTRIBUTING.md)
+* [DOCUMENTATION.md](DOCUMENTATION.md)
+
+## Screenshots
+
+Here is an example of the syntax highlighting provided by VimTeX. The conceal
+feature is active on the right-hand side split. The example is made by
+@DustyTopology with the
+[vim-colors-xcode](https://github.com/arzg/vim-colors-xcode) colorscheme with
+some minor adjustments [described
+here](https://github.com/lervag/vimtex/issues/1946#issuecomment-843674951).

+VimTeX's core motions, text-editing commands, and text objects.
+
+## Features
+
+Below is a list of features offered by VimTeX. The features are accessible as
+both commands and mappings. The mappings generally start with `<localleader>l`,
+but if desired one can disable default mappings to define custom mappings. 
+Nearly all features are enabled by default, but each feature may be disabled if
+desired. The two exceptions are code folding and formating, which are disabled
+by default and must be manually enabled.

+
+## Other relevant plugins
+
+Even though VimTeX provides a lot of nice features for working with LaTeX
+documents, there are several features that are better served by other,
+dedicated plugins. For a more detailed listing of these, please see [`:help
+vimtex-and-friends`](doc/vimtex.txt#L540).
+
+### Linting and syntax checking
+
+  * [ale](https://github.com/w0rp/ale)
+  * [neomake](https://github.com/neomake/neomake)
+  * [syntastic](https://github.com/vim-syntastic/syntastic)
+
+### Snippets and templates
+
+  * [UltiSnips](https://github.com/SirVer/ultisnips)
+  * [neosnippet](https://github.com/Shougo/neosnippet.vim)
+
+### Tag navigation
+
+  * [vim-gutentags](https://github.com/ludovicchabant/vim-gutentags)
+
+## Alternatives
+
+The following are some alternative LaTeX plugins for Vim:
+
+* [LaTeX-Suite](http://vim-latex.sourceforge.net)
+
+    The main difference between VimTeX and LaTeX-Suite (aka vim-latex) is
+    probably that VimTeX does not try to implement a full fledged IDE for LaTeX
+    inside Vim. E.g.:
+
+    * VimTeX does not provide a full snippet feature, because this is better
+      handled by [UltiSnips](https://github.com/SirVer/ultisnips) or
+      [neosnippet](https://github.com/Shougo/neosnippet.vim) or similar snippet
+      engines.
+    * VimTeX builds upon Vim principles: It provides text objects for
+      environments, inline math, it provides motions for sections and
+      paragraphs
+    * VimTeX uses `latexmk`, `latexrun`, `tectonic` or `arara` for compilation
+      with a callback feature to get instant feedback on compilation errors
+    * VimTeX is very modular: if you don't like a feature, you can turn it off.
+
+* [TexMagic.nvim](https://github.com/jakewvincent/texmagic.nvim)
+
+    "A simple, lightweight Neovim plugin that facilitates LaTeX build engine
+    selection via magic comments. It is designed with the TexLab LSP server's
+    build functionality in mind, which at the time of this plugin's inception
+    had to be specified in init.lua/init.vim and could not be set on
+    a by-project basis."
+
+    This plugin should be combined with the TexLab LSP server, and it only
+    works on neovim.
+
+* [LaTeX-Box](https://github.com/LaTeX-Box-Team/LaTeX-Box)
+
+    VimTeX currently has most of the features of LaTeX-Box, as well as
+    some additional ones. See [here](#features) for a relatively complete list
+    of features.
+
+    One particular feature that LaTeX-Box has but VimTeX misses, is the ability
+    to do single-shot compilation _with callback_. This functionality was
+    removed because it adds a lot of complexity for relatively little gain
+    (IMHO).
+
+* [AutomaticTexPlugin](http://atp-vim.sourceforge.net)
+* [vim-latex-live-preview](https://github.com/xuhdev/vim-latex-live-preview)

+plugins for Vim, see:

+# VimTeX Visualized
+
+This page contains animated GIFs that demonstrate many of the core VimTeX
+editing features listed in `:help vimtex-features`. The related mappings are
+documented in detail at `:help vimtex-mappings`. The GIFs and accompanying

+[@ejmastnak](https://github.com/ejmastnak)'s guide to [Getting started with the
+VimTeX plugin](https://www.ejmastnak.com/tutorials/vim-latex/vimtex.html).
+
+Hopefully, the animations can give you a clearer mental image of what VimTeX's
+mappings do and how you might use them. You may want to scroll through this page
+while simultaneously looking through `:help vimtex-features`—the animations
+should nicely complement the plain-text documentation.

+## Motion commands
+
+### Navigating sections
+
+Use `]]` to jump to the beginning of the next `\section`, `\subsection` or
+`\subsubsection`, whichever comes first. Use `[[` to jump backward through
+sections, and see the similar shortcuts `][` and `[]` in the VimTeX
+documentation at `:help <Plug>(vimtex-][)` and `:help <Plug>(vimtex-[])`.
+
+![Navigating sections](https://github.com/lervag/vimtex-media/blob/main/gif/move/move-section.gif)
+
+### Navigating environments
+
+Use `]m` and `[m` to jump to the next or previous environment `\begin{}`
+command. See the VimTeX documentation for the similar shortcuts `]M` and `[M`,
+described in `:help <Plug>(vimtex-]M)` and `:help <Plug>(vimtex-[M)`.
+
+![Navigating environments](https://github.com/lervag/vimtex-media/blob/main/gif/move/move-environment.gif)
+
+### Navigating math zones
+
+Use `]n` and `[n` to jump to the beginning of the next or previous math zone.
+See the VimTeX documentation for the similar shortcuts `]N` and `[N`,
+described in `:help <Plug>(vimtex-]N)` and `:help <Plug>(vimtex-[N)`.
+
+![Navigating math zones](https://github.com/lervag/vimtex-media/blob/main/gif/move/move-math.gif)
+
+### Navigating frames
+
+Use `]r` and `[r` to jump to the beginning of the next or previous Beamer
+`frame` environment. See the VimTeX documentation for the similar shortcuts
+`]R` and `[R`, described in `:help <Plug>(vimtex-]R)` and `:help
+<Plug>(vimtex-[R)`.
+
+![Navigating frames](https://github.com/lervag/vimtex-media/blob/main/gif/move/move-frame.gif)
+
+### Navigating matching delimiters
+
+Use `%` to move between matching delimiters, inline-math `$` delimiters, and LaTeX environments.
+
+![Navigating matching delimiters](https://github.com/lervag/vimtex-media/blob/main/gif/move/move-matching.gif)
+
+## Text objects
+
+VimTeX provides text objects for commands, delimiters, environments,
+math zones, sections, and items. The following GIFs use Vim's visual
+mode to show the scope of the text objects.
+
+### The math text object
+
+The `i$` and `a$` text objects select inline math, display math, and
+common math environments.
+
+![The math text object](https://github.com/lervag/vimtex-media/blob/main/gif/text-objects/obj-math.gif)
+
+### The section, delimiter, and command text objects
+
+The `iP` and `aP` text objects select LaTeX sections (their
+subsection variations); the `id` and `ad` objects select delimiters
+(parentheses, brackets, braces...); the `ic` and `ac` objects select
+LaTeX commands.
+
+![The section, delimiter, and command text objects](https://github.com/lervag/vimtex-media/blob/main/gif/text-objects/obj-sec-delim-cmd.gif)
+
+### The environment and item text objects
+
+The `ie` and `ae` text objects select LaTeX environments and the `im`
+and `am` objects select items in enumerated environments.
+
+![The environment and item text objects](https://github.com/lervag/vimtex-media/blob/main/gif/text-objects/obj-env-item.gif)
+
+## Deleting surrounding LaTeX content
+
+### Delete surrounding commands
+
+Use `dsc` to delete a LaTeX command while preserving the command's argument(s);
+the `dsc` mapping also recognizes and correctly deletes parameters inside square
+brackets.
+
+![`dsc`](https://github.com/lervag/vimtex-media/blob/main/gif/change-delete/dsc.gif)
+
+### Delete surrounding environments
+
+Use `dse` to delete the `\begin{}` and `\end{}` declaration surrounding a LaTeX
+environment without changing the environment contents.
+
+![`dse`](https://github.com/lervag/vimtex-media/blob/main/gif/change-delete/dse.gif)
+
+### Delete surrounding math zones
+
+Use `ds$` to delete surrounding math zones (display math, standard environments,
+and inline math) without changing the math contents.
+
+![`ds$`](https://github.com/lervag/vimtex-media/blob/main/gif/change-delete/dsm.gif)
+
+### Delete surrounding delimiters
+
+Use `dsd` to delete delimiters (e.g. `()`, `[]`, `{}`, *and* any of their `\left
+\right`, `\big \big` variants) without changing the enclosed content.
+
+![`dsd`](https://github.com/lervag/vimtex-media/blob/main/gif/change-delete/dsd.gif)
+
+
+## Changing surrounding LaTeX content
+
+### Change surrounding commands
+
+Use `csc` to change a LaTeX command while preserving the command's argument(s).
+
+![`csc`](https://github.com/lervag/vimtex-media/blob/main/gif/change-delete/csc.gif)
+
+### Change surrounding environments
+
+Use `cse` to change the type of a LaTeX environment without changing the
+environment contents.
+
+![`cse`](https://github.com/lervag/vimtex-media/blob/main/gif/change-delete/cse.gif)
+
+### Change surrounding math zones
+
+Use `cs$` to change the type of surrounding math zone without changing the math
+contents. You can switch between display math, standard environments, and inline
+math.
+
+![`cs$`](https://github.com/lervag/vimtex-media/blob/main/gif/change-delete/csm.gif)
+
+### Change surrounding delimiters
+
+Use `csd` to change delimiters (e.g. `()`, `[]`, `{}`, and any of their `\left
+\right`, `\big \big` variants) without changing the enclosed content; the `csd`
+command is "smart" and correctly recognizes and preserves `\left \right`-style
+modifiers.
+
+![`csd`](https://github.com/lervag/vimtex-media/blob/main/gif/change-delete/csd.gif)
+
+## Toggling commands
+
+### Toggling starred commands and environments
+
+Use `tsc` and `tse` to toggle between starred and un-starred versions of
+commands and environments, respectively.
+
+![`tsc` and `tse`](https://github.com/lervag/vimtex-media/blob/main/gif/toggle/tsc-tse.gif)
+
+### Toggling between inline and display math
+
+Use `ts$` to toggle between inline math, display math, and standard math environments.
+
+![`ts$`](https://github.com/lervag/vimtex-media/blob/main/gif/toggle/tsm.gif)
+
+### Toggling delimiter modifiers
+
+Use `tsd` to change between plain and `\left`/`\right` versions of delimiters.
+Use the `g:vimtex_delim_toggle_mod_list` variable to add more modifiers  to the
+delimiter toggle list. (e.g. `\big` as in the GIF below)
+
+![`tsd`](https://github.com/lervag/vimtex-media/blob/main/gif/toggle/tsd.gif)
+
+### Toggling fractions
+
+Use `tsf` to toggle between inline and `\frac{}{}` versions of fractions.
+
+![`tsf`](https://github.com/lervag/vimtex-media/blob/main/gif/toggle/tsf.gif)
+
+## How these GIFs were made
+
+(Based on interest and discussion in issue
+[#2685](https://github.com/lervag/vimtex/issues/2685).)
+
+The basic toolkit is [Menyoki](https://github.com/orhun/menyoki) for
+recording the GIFs and [screenkey](https://gitlab.com/screenkey/screenkey) to
+display the keys being typed, all running on a Linux system using the X11
+window system.
+
+On top of this are some aesthetic details to make the GIFs look nicer,
+including:
+
+- [Goyo](https://github.com/junegunn/goyo.vim) to remove Vim peripherals
+  (status bar, line numbers, etc.) for a cleaner look
+- [Limelight](https://github.com/junegunn/limelight.vim) to draw focus to the
+  currently selected paragraph (and gray out the rest of the document)
+- Screen recording region (crop, basically) set via Menyoki to exactly capture
+  the terminal window (and not e.g. the rest of my desktop)
+- Enlarged terminal font for the duration of the GIF recording for better
+  readability
+- Vim and screenkey color schemes and fonts aligned for visual consistency.
+
+The aesthetic details and cropping are wrapped in shell scripts for

+INTRODUCTION                                              *vimtex-introduction*
+
+VimTeX provides convenient functionality for editing LaTeX documents.  The
+main goal of VimTeX is to be simple, functional, and to be easy to customize
+and evolve.
+
+The documentation is understandably too long for a full read through. It is
+recommended that new users read or skim the entire introduction, as it should
+give a clear idea of what VimTeX is and is not. The remaining part of the
+documentation should then be considered a reference for the various parts of
+the plugin.
+
+------------------------------------------------------------------------------
+COMMENT ON INTERNAL TEX PLUGIN                        *vimtex-comment-internal*
+
+Vim ships with pretty decent LaTeX support out of the box. In particular, it
+provides syntax highlighting (|ft-tex-syntax|), indentation (see the source
+file $VIMRUNTIME/indent/tex.vim for the documentation), and some sensible
+options (|ft-tex-plugin|).
+
+                                                            *vimtex-tex-flavor*
+When VimTeX is active, it will override the internal TeX plugin for the
+filetype `tex` (|ft-tex-plugin|), both for syntax highlighting and for
+filetype specific features. To prevent the unexpected behaviour where `.tex`
+files by default will be recognized as the filetype `plaintex`
+(|ft-plaintex-syntax|) for e.g. empty documents, VimTeX overrides the filetype
+detection for `.tex`. The user may prevent this overriding by specifying the
+|g:tex_flavor| option something different than `'latex'`.
+

+REQUIREMENTS                                              *vimtex-requirements*
+
+The following is a list of specific requirements for running VimTeX and some
+of its key features. Windows users should also read |vimtex-faq-windows|.
+
+Vim version ~
+                                                         *vimtex_version_check*
+  VimTeX requires Vim version 8.2.3995 or neovim version 0.9.5. It will not
+  load for older versions, unless one adds >vim
+
+    let g:vimtex_version_check = 0
+<
+  to one's `vimrc` file. This might work, but issues due to older versions
+  than the mentioned here will be ignored.
+
+Vim configuration ~
+
+  VimTeX requires |:filetype-plugin-on| and optionally |:filetype-indent-on|.
+
+  There are several features in VimTeX that depend on the syntax parsing used
+  for syntax highlighting. Examples include functions like
+  |vimtex#syntax#in_mathzone| and text objects like |<plug>(vimtex-i$)|. This
+  is important to be aware of especially for neovim users who are interested
+  in Tree-sitter. If you use Tree-sitter for syntax highlighting and thus
+  disable the normal Vim syntax feature, then you will also lose the VimTeX
+  features that depend on the built-in syntax parser. For more info, see
+  |vimtex-faq-treesitter|.
+
+  Some of the VimTeX scripts contain UTF-8 characters, and as such, it is
+  necessary to have the 'encoding' option set to utf8. This is not necessary
+  in neovim, only in Vim. Add the following to your vimrc file: >vim
+
+    set encoding=utf8
+
+Compiler backend ~
+
+  VimTeX uses `latexmk`, `latexrun`, `tectonic` or `arara` to compile the LaTeX document.
+
+    `latexmk`: http://users.phys.psu.edu/~collins/software/latexmk-jcc
+    "a perl script for running LaTeX the correct number of times to resolve
+  cross references, etc; it also runs auxiliary programs (e.g. bibtex).  It
+  has a number of other useful capabilities, for example to start a previewer
+  and then run latex whenever the source files are updated, so that the
+  previewer gives an up-to-date view of the document. The script runs on both
+  UNIX and MS-WINDOWS (XP, etc)." [Copied from the latexmk page.]
+  (|vimtex-compiler-latexmk|)
+
+    `latexrun`: https://github.com/aclements/latexrun
+    Similar to `latexmk` in that it runs the desired LaTeX engine an
+  appropriate number of times, including `bibtex`/`biber`. However, it differs
+  in philosophy in that it only does the build part. It does not support
+  continuous builds, nor automatic starting of the viewer. However, it does
+  parse the output log in order to provide a more concise list of relevant
+  warnings and error messages (this has currently not been adapted to VimTeX,
+  as of yet). (|vimtex-compiler-latexrun|)
+
+    `tectonic`: https://tectonic-typesetting.github.io/
+    `tectonic` is a complete, self-contained TeX/LaTeX engine, powered by XeTeX
+  and TeXLive. It doesn't support continuous build like `latexmk` but it
+  presents other worth mentioning features such as automatic support file
+  downloading along with reproducible builds and full Unicode and OpenType
+  fonts support thanks to the power of XeTeX. (|vimtex-compiler-tectonic|)
+
+    `arara`: https://github.com/cereda/arara
+    `arara` is a TeX automation tool similar to the above mentioned tools,
+  but where the compilation behaviour is typically defined in the preamble
+  of the document. (|vimtex-compiler-arara|)
+
+Clientserver ~
+                                                          *vimtex-clientserver*
+  Vim requires |+clientserver| in order to allow inverse search from the PDF
+  viewer to Vim (see |vimtex-synctex-inverse-search|). The clientserver is
+  used by VimTeX. Thus, if one uses Vim one must ensure that it starts
+  a server. Neovim does not have this requirement.
+
+  A server will be started automatically if Vim is running on Windows or if it
+  is running in a GUI (gVim). If you use Vim under a terminal in Linux or
+  MacOS, a server will not be started by default. Also, MacVim users should be
+  aware of some differences from regular Vim and should therefore read
+  |macvim-clientserver| carefully.
+
+  You can use |remote_startserver()| to start a server from your `vimrc` file.
+  The following vimrc configuration snippet will ensure that Vim starts with
+  a server, if possible: >vim
+
+    if empty(v:servername) && exists('*remote_startserver')
+      call remote_startserver('VIM')
+    endif
+<
+  Alternatively, Vim can be started with the command line option
+  `--servername`, e.g. `vim --servername VIM` . The simplest way to ensure
+  this is to add an alias to your `.bashrc` (or similar), that is, add: >bash
+
+    alias vim='vim --servername VIM'
+<
+  One can use |serverlist()| to check whether a server was successfully
+  started, e.g. with `:echo serverlist()`.
+
+  Neovim does not implement the same clientserver feature. Instead, it
+  implements the MessagePack-RPC protocol (see |RPC|). VimTeX relies on this
+  protocol in the same fashion as the clientserver. Both Vim and neovim have
+  the |v:servername| variable that contains the name/location of the server
+  with which we need to communicate.
+
+------------------------------------------------------------------------------
+SUPPORT FOR MULTI-FILE PROJECTS                             *vimtex-multi-file*
+
+VimTeX supports most multi-file documents and has several methods to locate
+the `main` document. Locating this file is very important, because the main
+file is the one that must be compiled.
+
+The default method for locating the main file uses a directory-scan algorithm
+that searches for a main LaTeX file, see method 6 below. It is expected to
+work in the vast majority of cases.
+
+There are several alternative methods for specifying the main file that can be
+more flexible and are relevant for certain work flows and use cases. These
+methods all require some explicit declaration of the main file and are
+therefore tried prior to the directory scan.
+
+The complete list of methods in the order of priority is as follows and are
+then described in more detail:
+
+1. Buffer variable
+2. TeX root directive
+3. Subfiles package
+4. File `.latexmain` specifier
+5. Local `latexmkrc` file specifier (from `@default_files` option)
+6. Directory scan
+
+                                                                 *b:vimtex_main*
+Buffer variable ~
+  The main file may be specified through the buffer variable `b:vimtex_main`.
+  To take effect, it has to be set prior to loading the buffer. If set after
+  the buffer is already loaded, |:VimtexReloadState| (by default bound to
+  |<localleader>lX|) can be used to make VimTeX aware of its new value.
+  A convenient way to use this feature is to add an |BufReadPre| |autocmd| in
+  one's |vimrc|. An example is warranted: >vim
+
+    augroup VimTeX
+      autocmd!
+      autocmd BufReadPre /path/to/project/*.tex
+            \ let b:vimtex_main = '/path/to/project/main.tex'
+    augroup END
+<
+  Note: When writing such rules, one should be aware that the `*` is not the
+        same as regular globbing because it also includes directory
+        separators. Also, one should use `/` on every OS. See |file-pattern|
+        for more info on the |autocmd| file pattern syntax.
+
+  Note: Users may be interested in the concept of project specific vim
+        configuration. This is supported in Vim, see 'exrc' and 'secure'.
+        There are also several plugins to help work with project specific
+        settings, such as:
+
+        * https://github.com/embear/vim-localvimrc
+        * https://github.com/tpope/vim-projectionist
+        * https://github.com/jenterkin/vim-autosource
+        * https://github.com/ii14/exrc.vim
+        * https://github.com/MarcWeber/vim-addon-local-vimrc/
+        * https://github.com/MunifTanjim/exrc.nvim (neovim only)
+        * See also:
+          https://superuser.com/questions/598947/setting-vim-options-only-for-files-in-a-certain-directory-tree/598970#598970
+
+                                                              *vimtex-tex-root*
+TeX root directive ~
+  It is also possible to specify the main TeX file with a comment in one of
+  the first five lines of the current file. This is often referred to as a TeX
+  directive, see |vimtex-tex-directives| for more info. The syntax is best
+  described by some examples: >latex
+
+    %! TEX root = /path/to/my-main.tex
+    % ! TeX root = ../*.tex
+    %!Tex Root=**/main.tex
+    %! TeX root: ../main.tex
+<
+  As can be seen, the words "tex root" are recognized regardless of casing and
+  the spaces are ignored. Also, both a colon and an equal sign can be used.
+
+  VimTeX parses this directive during initialization. Thus, users should be
+  aware that they need to reload (with |:VimtexReload|) or restart Vim/neovim
+  if they change the TeX root directive.
+
+  Note: It is allowed to use a globbing pattern (see |wildcards|). If there
+        are multiple matches, then VimTeX will ask for input when the buffer
+        is opened.
+
+                                                               *vimtex-subfiles*
+                                                                 *vimtex-import*
+Subfiles package ~
+  VimTeX also supports the `import` [0] and the `subfiles` [1] packages that
+  can be used to make it easier to work with multi-file projects. If one uses
+  the `subfiles` package, the |:VimtexToggleMain| command is particularly
+  useful. Also note the option |g:vimtex_subfile_start_local|, which can be
+  used to automatically start in the local mode when opening a subfile
+  document.
+
+  With `subfiles`, included files will typically look like this: >latex
+
+    \documentclass[<main-path>]{subfiles}
+    \begin{document}
+    ...
+    \end{document}
+<
+  Here `<main-path>` is the path to the main file. It must be specified as
+  relative to the particular subfile. So, given the structure: >
+
+    main.tex
+    sub/sub.tex
+<
+  The header in `sub.tex` should be `\documentclass[../main.tex]{subfiles}`.
+  Absolute paths like `/home/user/main.tex` are also allowed and should work
+  as expected.
+
+  [0]: https://www.ctan.org/pkg/import
+  [1]: https://www.ctan.org/pkg/subfiles
+
+File .latexmain specifier ~
+  In some cases, it might be preferable to specify the main file by creating
+  an indicator file.  The indicator file should be an empty file, and the name
+  must be the name of the desired main file with `.latexmain` appended.  An
+  example should make this clear: >
+
+    path/file.tex
+    path/file.tex.latexmain
+    path/sections/file1.tex
+    path/sections/file2.tex
+<
+  Here `path/file.tex.latexmain` indicates for `file1.tex` and `file2.tex`
+  that `path/file.tex` is the main LaTeX file.
+
+Local latexmkrc file specifier ~
+  It is possible to specify to latexmk which files to compile with the
+  `@default_files` option in the `latexmkrc` configuration file. VimTeX
+  supports reading this option in any LOCAL `latexmkrc` or `.latexmkrc` file.
+
+  Note: `@default_files` is a list of files, VimTeX will use the first
+        entry that is found.
+
+Directory scan ~
+  If the above methods don't give an appropriate candidate for a main file of
+  the present file, then a search for a suitable main file from the current
+  directory and upwards is started.
+
+  A candidate `.tex` file qualifies as a main file if the following three
+  requirements are all satisfied:
+
+  1. It includes the present file, either directly or indirectly.
+  2. The expanded content contains a `\documentclass` line near the top.
+  3. The expanded content contains `\begin{document}`.
+
+  Notice that the main file itself does not need to contain the
+  `\documentclass` line and `\begin{docment}`, since these can stem from
+  included `.tex` files. The option |g:vimtex_include_indicators| is used by
+  the parser to specify commands that include `.tex` files for the recursive
+  expansion.
+
+  In cases where automatic detection of the main file through the directory
+  scan fails, one may explicitly set up method 1 to 5 instead. The
+  |vimtex-tex-root| is usually a good alternative.
+
+  Note: Recursive directory descents are not performed to find the main file.
+        That is, if the current file is `./B/chapter.tex` then `./A/main.tex`
+        will not be found as the main file, because the descent to
+        subdirectory `./A/` is not performed.
+
+------------------------------------------------------------------------------
+SUPPORT FOR TEX DIRECTIVES                              *vimtex-tex-directives*
+
+VimTeX supports two of the commonly used TeX directives [0]: the TeX root and
+the TeX program directive. The TeX root directive was already described above,
+see |vimtex-tex-root|.
+
+                                                           *vimtex-tex-program*
+The TeX program directive works by specifying the TeX compiler program in
+a comment in one of the first lines of the main project file. It is parsed
+only when it is required by a compiler backend.
+
+The syntax is best explained with an example: >latex
+
+  %! TeX program = lualatex
+  %! TEX TS-program = xelatex
+
+The left-hand side must contain the text "tex program" or "tex ts-program" and
+as with |vimtex-tex-root|, the words are recognized regardless of casing and
+the spaces are ignored. The right-hand side must correspond to a key in the
+|g:vimtex_compiler_latexmk_engines| or |g:vimtex_compiler_latexrun_engines|
+dictionaries. See also [0,1].

+
+------------------------------------------------------------------------------
+PACKAGE DETECTION                                    *vimtex-package-detection*
+
+VimTeX maintains a list of latex packages that are required by the current
+project. This list is used by VimTeX for instance to determine which commands
+to suggest during command completion (see |vimtex-complete-commands|) and
+which packages to look up documentation for (see |vimtex-doc-package|). The
+list can be viewed with |:VimtexInfo|.
+
+The package list is determined in two ways:
+
+1. If a `.fls` file exists having the name of the main file, it is scanned.
+   This file is created by `latex` (or `pdflatex`, `xelatex`, ...) if it is
+   run with the `-recorder` option (which is set by default when using
+   latexmk, unless overridden in an initialization file). Parsing the `.fls`
+   file is done both at VimTeX initialization and after each successful
+   compilation, if possible.
+
+   Note: Parsing after successful compilations requires that one uses
+         a) continuous compilation with callbacks (see the `callback` option
+            for |g:vimtex_compiler_latexmk|), or
+         b) single-shot compilation.
+
+2. Otherwise, the preamble is parsed for `\usepackage` statements. This is
+   slower and less accurate than `.fls` file parsing. Therefore, it is only
+   done during VimTeX initialization. If desired, one may manually reload
+   VimTeX to parse the preamble again during an editing session. See
+   |:VimtexReload| and |<plug>(vimtex-reload)| (by default mapped to
+   `<localleader>lx`).
+
+------------------------------------------------------------------------------
+INTEGRATION WITH OTHER PLUGINS                             *vimtex-and-friends*
+
+VimTeX provides a lot of convenient and useful features for working with LaTeX
+files. However, there are several features that one might expect to be part of
+VimTeX, but that are left out because they are better served by other plugins.
+Let's call them "friends".
+
+The following is an overview of some such features. We also try to give hints
+and suggestions for how to best integrate with VimTeX experience, if that is
+applicable.
+

+Linting and syntax checking ~
+                                                            *vimtex-af-linting*
+  VimTeX has some support for linting through the |:compiler| command, see
+  |vimtex-lint|. There exists several more dedicated, automatic linting
+  plugins. The following plugins have support for (La)TeX syntax checking
+  through `lacheck` [0], `chktex` [1], and `proselint` [2].
+
+    `ale`         https://github.com/dense-analysis/ale
+    `neomake`     https://github.com/neomake/neomake
+    `syntastic`   https://github.com/vim-syntastic/syntastic
+
+  `neomake` also supports `rubberinfo` [3]. One may also be interested in
+  `blacktex` [4], which may be used to clean up/fix LaTeX code.

+  Snippets and/or templates are provided by for instance `neosnippet` and
+  `UltiSnips`. See |vimtex-neosnippet| and |vimtex-UltiSnips| for more info.

+Tag navigation ~

+  One may navigate by tags with the |CTRL-]| mapping, e.g. from
+  `\eqref{eq:example}` to the corresponding `\label{eq:example}`. However,
+  this requires that a tag file has been generated with |ctags|. I recommend
+  that one uses the maintained version of ctags [0]. In addition,
+  I recommend that one uses a plugin that automatically generates the tag
+  files as necessary, e.g. |gutentags| [1].
+
+  See |vimtex-faq-tags| and |vimtex-faq-tags-bibtex| for concrete examples.

+Manipulate surrounding commands/delimiters/environments ~
+                                                           *vimtex-af-surround*
+  VimTeX provides mappings that change, delete and toggle commands,
+  delimiters and environments (see the `ds`, `cs` and `ts` family of
+  mappings listed under |vimtex-default-mappings|).  These mappings are
+  inspired by the great `surround.vim` [0] (|surround.txt|) by Tim Pope,
+  which provides mappings to manipulate surrounding delimiters such as `''`,
+  `""`, `()`, `[]`, `{}`, and `<>`.  As such, the mappings from VimTeX
+  should work well together with, and as an extension of, `surround.vim`.
+  Consider also the customization described under |vimtex-faq-surround|.
+  The mappings may be repeated with the dot (|.|) command. See also
+  |g:vimtex_delim_list| if you are interested in customizing the delimiter
+  pairs that are recognized.
+
+  A different possibility is to use `vim-sandwich` [1] (|sandwich.txt|) by
+  Machakann, which may be considered a generalisation of `surround.vim` in
+  that it can handle much more complex sets of delimiters.  `vim-sandwich`
+  is relatively easy to expand with custom surroundings and has built in
+  support for LaTeX-specific surroundings such as quotations and math
+  delimiters.  For a list of supported delimiters, see
+  |sandwich-filetype-recipes|.  `vim-sandwich` supports `vim-repeat` [2] in
+  addition to `visualrepeat.vim` [3].
+
+  Note: The default mappings of `vim-sandwich` differ from those of
+    `surround.vim`, in that they use `s` as the prefix.  E.g., to add
+    surroundings, one uses `sa{motion/textobject}{type-of-surrounding}`
+    instead of `ys{motion/textobject}{type-of-surrounding}`.  If one prefers
+    the map variants from `surround.vim`, these are also available as an
+    option, see |sandwich-miscellaneous|.  And it is also easy to define
+    custom mappings, if one prefers that.
+
+  Note: `vim-sandwich` actually consists of three plugins that work
+    together.  One should make sure to read the docs for all of them:
+    |sandwich.txt|, |operator-sandwich.txt|, and |textobj-sandwich.txt|.

+Enhanced matching and highlighting of delimiters ~
+                                                *vimtex-af-enhanced-matchparen*
+  VimTeX highlights and allows navigation between matching pairs of
+  delimiters including those in math mode, such as `\bigl(` and `\bigr)`, and
+  the `\begin` and `\end` tags of environments. However, the implementation
+  may be slow (see also |vimtex-faq-slow-matchparen|, and so one may use
+  |g:vimtex_matchparen_enabled| to disable the highlighting).
+
+  Alternatively, one may use the plugin |match-up| [0], which offers enhanced
+  |matchparen| highlighting and `matchit.zip` style motions and |text-objects|
+  for a variety of file types.  For LaTeX documents, it:
+    - Extends highlighting and the `%` motion to a number of middle
+      delimiters including
+        - `\bigm` and `\middle` marked delimiters
+        - `\item`s in `itemize` and `enumerate` environments
+        - `\toprule`, `\midrule`, `\bottomrule` in the `tabular` environment.
+        - `\if`, `\else` and `\endif`
+      Note: VimTeX does not support highlighting the middle delimiters.
+    - Adds motions, `g%`, `[%`, and `]%` and text objects, `a%` and `i%` which move
+      between matching delimiters and operate on delimited text.
+
+  For example, with match-up enabled, >latex
+
+    \left( \frac{a}{b} \middle| q \right)
+<
+  the motion `%` will cycle through `\left(`, `\middle|`, and `\right)`, whereas
+  with VimTeX only `\left(` and `\right)` will be matched.  The motion `g%`
+  will do the same, except in reverse.
+
+  To enable the plugin match-up after installation, add the following to
+  your vimrc: >vim
+
+    let g:matchup_override_vimtex = 1
+<
+  Matching may become computationally intensive for complex LaTeX documents.
+  If you experience slowdowns while moving the cursor, the following option
+  is recommended to delay highlighting slightly while navigating: >vim
+
+    let g:matchup_matchparen_deferred = 1
+<
+  Note: The exact set of delimiters recognized may differ between match-up
+    and VimTeX.  For example, the mappings `da%` and `dad` will not in general
+    be identical, particularly if you have customized VimTeX's delimiters.

+Formatting ~
+                                                         *vimtex-af-formatting*
+  VimTeX has a custom |formatexpr| that may be enabled with the option
+  |g:vimtex_format_enabled|. However, there are a lot of different styles for
+  formatting LaTeX manuscripts. These are typically much more relevant when
+  writing in collaboration with others. A good reference on this topic is [0],
+  and note in particular the box "Directives for using LaTeX with version
+  control systems".
+
+  The most basic style is to hard wrap lines at a given column, e.g. 80
+  columns, and this is exactly the type of formatting that is supported by
+  VimTeX. However, this is usually not very friendly when collaborating with
+  others, as it tends to mess up diffs between versions of the document.
+  Instead, one might want to consider one of these:
+
+    a) keeping each sentence on a line (use soft wrapping)
+    b) add additional indentation for split sentences [1]
+    c) use semantic line feeds [2]
+
+  In order to make it easier to use one of these styles of formatting, one may
+  want to use an external formatter:
+
+    - latexindent.pl [3]
+    - vim-bucky [4] (note: this is an alpha version as of October 2018)
+    - semantic-linebreaker [5] (note: this is a web-based tool)
+
+  Further, there are a range of Vim plugins that can be used to format your
+  document with external tools. Some of these also allow autoformatting of
+  some kind. In no particular order:
+
+    - neoformat [6]
+    - vim-codefmt [7]
+    - vim-autoformat [8]
+    - ale [9]
+    - vim-sentence-chopper [10]

+Filetype plugin for bib files ~
+                                                       *vimtex-af-ftplugin-bib*
+  VimTeX is not a full filetype plugin for bibliography files (`.bib`). However,
+  it does alter the 'comments' and 'commentstring' options and provide basic
+  indentation and folding; see |g:vimtex_indent_bib_enabled| and
+  |g:vimtex_fold_bib_enabled|, respectively.
+
+  Here are a couple of other related Vim plugins and external tools that might
+  be of interest:
+
+  - `bibtool`
+    An external tool for formatting, sorting, filtering, merging, and more of
+    `.bib` files.
+    http://www.gerd-neugebauer.de/software/TeX/BibTool/
+  - `GooseBib`
+    Some simple command-line tools to clean-up / modify BibTeX files.
+    https://github.com/tdegeus/GooseBib
+  - `bibtex-tidy`
+    Another tool for formatting and cleaning `.bib` files.
+    https://flamingtempura.github.io/bibtex-tidy/
+  - `tbibtools`
+    A set of ruby-based bibtex-related utilities for sorting, reformatting,
+    listing contents, and so on. Has optional Vim integration.
+    https://www.vim.org/scripts/script.php?script_id=1915

+Language servers ~
+                                                                *vimtex-af-lsp*
+  In recent years, language servers (LSPs) [0] have become very popular. There
+  is a language server for LaTeX and bibtex called texlab [1]. It may be
+  interesting both as an alternative to VimTeX and/or an addition.
+
+  There is currently no known conflict between texlab and VimTeX, although
+  there is some feature overlap. E.g., both texlab and VimTeX provides
+  advanced completion in various contexts. As texlab is written in Rust and
+  runs in a separate thread, it is no surprise that it will have a clear
+  performance advantage. However, VimTeX does use caches to speed up
+  completion which should in most cases work well.
+
+  To use texlab, one must use an LSP client, e.g. |vim-lsp| [2], neovim's
+  built-in LSP client [3], or |coc-nvim| [4, 5]. See also this VimTeX issue
+  [6] for more information.
+
+  In addition to texlab, there is also a dedicated grammar and spell checking
+  language server called LTeX [7]. It relies on LanguageTool and supports both
+  LaTeX and other markup languages. It may be a useful tool to use in
+  conjunction with VimTeX as an alternative to |vimtex-grammar|.

+------------------------------------------------------------------------------
+DEFAULT MAPPINGS                                      *vimtex-default-mappings*
+
+VimTeX is designed to be controlled by a selection of mappings.  Note,
+though, that most of the mappings are also available as commands, see
+|vimtex-commands|.
+
+Many of the mappings use `<localleader>l` as a common prefix, where the
+default |<localleader>| is `\`. Thus, `<localleader>ll` will for most people
+mean `\ll`. The prefix may be changed with |g:vimtex_mappings_prefix|.
+
+The right-hand sides are provided as <plug>-mappings, see |using-<plug>|. For
+any given <plug> map, the default mapping will only be created if it does not
+already exist. This means that if a user defines a custom mapping, e.g. with >vim
+
+  nmap <space>li <plug>(vimtex-info)
+
+then the corresponding default left-hand side will not be mapped.
+
+If one prefers, one may disable all the default mappings through the option
+|g:vimtex_mappings_enabled|.  Custom mappings for all desired features must
+then be defined through the listed RHS <plug>-maps or by mapping the available
+commands.
+
+In the below list of mappings, LHS is the default mapping, RHS is the
+corresponding <plug>-maps, and MODE indicates in which vim mode the mappings
+are valid. See |map-modes| for an explanation of the various modes. The
+indicator refers to the prefix of the corresponding map command, e.g. `n`
+refers to an |nmap|, `nx` refers to both |nmap| and |xmap|, and so on.
+
+In addition to the mappings listed below, VimTeX provides convenient insert
+mode mappings to make it easier and faster to type mathematical equations.
+This feature is explained in more detail later, see |vimtex-imaps|.

+OPTIONS                                                        *vimtex-options*
+
+*g:vimtex_enabled*
+  Set to 0 to disable VimTeX.
+
+  Default value: Undefined.
+
+*g:vimtex_cache_root*
+  Specify the cache directory for VimTeX.
+
+  Default value:
+    `'$XDG_CACHE_HOME/vimtex'`   if `$XDG_CACHE_HOME` is defined
+    `'~/.cache/vimtex'`          otherwise
+
+*g:vimtex_cache_persistent*
+  Specify whether to use persistent caching.
+
+  Default value: 1
+
+*g:vimtex_compiler_enabled*
+  Use this option to disable/enable the `compiler` interface, see |vimtex-compiler|.
+
+  Default value: 1
+
+*g:vimtex_compiler_silent*
+  Set this to 1 or |v:true| to silence the compiler messages during start,
+  stop, and callbacks.
+
+  Default: 0
+
+*g:vimtex_compiler_method*
+  This option sets the compiler method. There are two ways to configure this
+  option:
+
+    i)  Explicity as a string.
+    ii) Dynamically through a function.
+
+  In the first variant, you can choose from the following list of compiler
+  methods:
+
+    Value      Documentation              Configuration ~
+    `latexmk`    |vimtex-compiler-latexmk|    |g:vimtex_compiler_latexmk|
+    `latexrun`   |vimtex-compiler-latexrun|   |g:vimtex_compiler_latexrun|
+    `tectonic`   |vimtex-compiler-tectonic|   |g:vimtex_compiler_tectonic|
+    `arara`      |vimtex-compiler-arara|      |g:vimtex_compiler_arara|
+    `generic`    |vimtex-compiler-generic|    |g:vimtex_compiler_generic|
+
+  In the second variant, the option must be specified as the name of
+  a function or a |Funcref|. Using a |Funcref| is only possible with Lua in
+  Neovim. The function is passed the path to the main TeX file as a single
+  string argument and must return the desired method as a string. The method
+  must be one from the above list of available methods.
+
+  Using a function allows a lot of flexibility in the choice of compiler
+  method. For instance, one could use `arara` for files that have `arara`
+  specifications at the top and fall back to `latexmk` for other files: >vim
+
+    function! SetCompilerMethod(mainfile)
+      if filereadable(a:mainfile)
+        for line in readfile(a:mainfile, '', 5)
+          if line =~# '^%\s*arara'
+            return 'arara'
+          endif
+        endfor
+      endif
+
+      return 'latexmk'
+    endfunction
+
+    let g:vimtex_compiler_method = 'SetCompilerMethod'
+<
+  Default value: `'latexmk'`
+
+*g:vimtex_compiler_clean_paths*
+  A list of additional path expressions for generated files that you want to
+  be cleaned by `:VimtexClean`. Note that this is NOT relevant for the
+  compiler backends |vimtex-compiler-latexmk| and |vimtex-compiler-latexrun|.
+  These backends provide their own clean implementations.
+
+  Each expression is a glob expression (see |glob()| and |wildcards|) and each
+  path is assumed rooted to the project root. For instance, to clean any
+  generated `_minted` paths (including directories), you could use something
+  like this: >vim
+
+    let g:vimtex_compiler_clean_paths = ['_minted*']
+<
+  Warning: Each resolved path will be deleted with |delete()| with the `"rf"`
+           flag!
+
+  Note: For `latexmk`, a similar feature is available with `$clean_ext`; see
+        the documentation https://texdoc.org/serve/latexmk/0.
+
+  Default value: `[]`
+
+*g:vimtex_compiler_latexmk*
+  This dictionary allows customization of the |vimtex-compiler-latexmk|
+  compiler. The values set by the user will take precedence over the default
+  values.
+
+  Default value: >vim
+
+    let g:vimtex_compiler_latexmk = {
+        \ 'aux_dir' : '',
+        \ 'out_dir' : '',
+        \ 'callback' : 1,
+        \ 'continuous' : 1,
+        \ 'executable' : 'latexmk',
+        \ 'hooks' : [],
+        \ 'options' : [
+        \   '-verbose',
+        \   '-file-line-error',
+        \   '-synctex=1',
+        \   '-interaction=nonstopmode',
+        \ ],
+        \}
+<
+  The default value shows which entries may be changed. Here the different
+  keys are explained in more detail:
+
+  aux_dir ~
+    This option sets the directory for auxiliary output files. It corresponds
+    to the `$aux_dir` option of `latexmk`. If the path is a relative path,
+    then it is considered relative to the main project file.
+
+    The value of this option should be either:
+      1) a string that represents a path, or
+      2) a |Funcref| with a single dictionary argument "file_info": >
+
+           file_info = {
+             root = …
+             target = …
+             target_basename = …
+             target_name = …
+             jobname = …
+           }
+<
+         This makes it possible to specify a dynamic `aux_dir`. It may be
+         easier to understand from an example: >vim
+
+           let g:vimtex_compiler_latexmk = {'aux_dir': {_ -> expand("%:t:r")}}
+<
+         With the above setting, the `aux_dir` is set to the base name of the
+         current file. E.g., If you do `vim test.tex`, the value becomes
+         `test`.
+
+    The specified auxiliary directory is created if it does not exist.
+
+    Note 1: This option only works with `latexmk` version 4.27 and later.
+    Note 2: If `$aux_dir` is added to `.latexmkrc`, then the `.latexmkrc` setting
+            will have priority.
+    Note 3: If |$VIMTEX_OUTPUT_DIRECTORY| is defined, it will have the highest
+            priority.
+    Note 4: The `-emulate_aux` option will be automatically passed to
+            `latexmk` if this option is not empty.
+
+  out_dir ~
+    This option sets the directory for the compilation output files. It
+    corresponds to the `$out_dir` option in `latexmk`. If the path is
+    a relative path, then it is considered relative to the main project file.
+
+    The value is either a string or a |Funcref|, similar to the above
+    described `aux_dir` key.
+
+    The specified output directory is created if it does not exist.
+
+    Note 1: This option only works with `latexmk` version 4.27 and later.
+    Note 2: If `$out_dir` is added to `.latexmkrc`, then the `.latexmkrc` setting
+            will have priority.
+    Note 3: If |$VIMTEX_OUTPUT_DIRECTORY| is defined, it will have the highest
+            priority.
+
+  callback ~
+    If enabled, this option tells `latexmk` to run |vimtex#compiler#callback|
+    after compilation is finished.
+
+  continuous ~
+    If enabled, `latexmk` will run in continuous mode, i.e. with the `-pvc`
+    argument. This means that the document is compiled automatically by
+    `latexmk` every time a related file has been changed, until the processes
+    is stopped.
+
+    If disabled, `latexmk` will run single shot compilations.
+
+    Note: The events |VimtexEventCompileStarted| and |VimtexEventCompileStopped|
+          are only relevant when this option is enabled.
+
+  executable ~
+    The name/path to the `latexmk` executable.
+
+  hooks ~
+    A list of |Funcref|s. If running in continuous mode, each hook will be
+    called for each line of output from `latexmk`, with that line as argument.
+    E.g., to show information about the compilation run numbers, one could do
+    this: >vim
+
+      function! Callback(msg)
+        let l:m = matchlist(a:msg, '\vRun number (\d+) of rule ''(.*)''')
+        if !empty(l:m)
+          echomsg l:m[2] . ' (' . l:m[1] . ')'
+        endif
+      endfunction
+      let g:vimtex_compiler_latexmk = { 'hooks': [function('Callback')] }
+<
+  options ~
+    This is a list of options that are passed to `latexmk`. The default
+    options should work well for most people.
+
+    Note: Options like `-pdf` or `-lualatex` should NOT be added to this list.
+          These are options used to specify the LaTeX processor/engine, see
+          instead |g:vimtex_compiler_latexmk_engines|.
+
+    Note: Options may also be specified indirectly to `latexmk` through both
+          a global and a project specific `.latexmkrc` file. One should know,
+          though, that options specified on the command line has priority, and
+          so if one wants to override one of the above default options, then
+          one has to set this key to a list that contains the desired options.
+
+*g:vimtex_compiler_latexmk_engines*
+  Defines a map between TeX program directive (|vimtex-tex-program|) and
+  compiler engine. This is used by |vimtex-compiler-latexmk| to define the
+  LaTeX program. The `_` key defines the default engine.
+
+  Note: If the TeX program directive is not specified within the main project
+        file, and if `$pdf_mode` is added to a project-specific `.latexmkrc`
+        file, then the compiler engine will be deduced from the value of
+        `$pdf_mode`. The supported values of `$pdf_mode` are 1 (pdflatex), 4
+        (lualatex) and 5 (xelatex). See the latexmk documentation for details.
+
+  Default value: >vim
+
+    let g:vimtex_compiler_latexmk_engines = {
+        \ '_'                : '-pdf',
+        \ 'pdfdvi'           : '-pdfdvi',

+        \ 'context (xetex)'  : '-pdf -pdflatex=''texexec --xtx''',
+        \}
+
+*g:vimtex_compiler_latexrun*
+  This dictionary allows customization of the |vimtex-compiler-latexrun|
+  compiler. The values set by the user will take precedence over the default
+  values.
+
+  Default value: >vim
+
+    let g:vimtex_compiler_latexrun = {
+        \ 'out_dir' : '',
+        \ 'options' : [
+        \   '-verbose-cmds',
+        \   '--latex-args="-synctex=1"',
+        \ ],
+        \}
+<
+  The default value shows which entries may be changed. Here the different
+  keys are explained in more detail:
+
+  out_dir ~
+    See `out_dir` key of |g:vimtex_compiler_latexmk|.
+
+  options ~
+    This is a list of options that are passed to `latexrun`. The default
+    options should work well for most people.
+
+    Note: By default, the option `-pdf` is also supplied to indicate the LaTeX
+          engine. This may be changed on a per project basis with TeX
+          directives, see |vimtex-tex-program| or the two compiler-specific
+          options |g:vimtex_compiler_latexmk_engines| and
+          |g:vimtex_compiler_latexrun_engines|. The latter two options may
+          also be used to change the default engine.
+
+*g:vimtex_compiler_latexrun_engines*
+  Defines a map between TeX program directive (|vimtex-tex-program|) and
+  compiler engine, i.e. as should be specified to the `--latex-cmd` argument
+  to `latexrun`. This is used by |vimtex-compiler-latexrun| to define the
+  LaTeX program. The `_` key defines the default engine.
+
+  Default value: >vim
+
+    let g:vimtex_compiler_latexrun_engines = {
+        \ '_'                : 'pdflatex',
+        \ 'pdflatex'         : 'pdflatex',

+
+*g:vimtex_compiler_tectonic*
+  This dictionary allows customization of the |vimtex-compiler-tectonic|
+  compiler. The values set by the user will take precedence over the default
+  values.
+
+  Default value: >vim
+

+        \ 'out_dir' : '',
+        \ 'hooks' : [],
+        \ 'options' : [

+        \   '--synctex'
+        \ ],
+        \}
+<
+  The default value shows which entries may be changed. Here the different
+  keys are explained in more detail:
+
+  out_dir ~
+    See `out_dir` key of |g:vimtex_compiler_latexmk|.
+
+  hooks ~
+    Same as |g:vimtex_compiler_latexmk| / `hooks`.
+
+  options ~
+    This is a list of options that are passed to `tectonic`. The default
+    options should work well for most people. For anyone who wishes to modify
+    these, please note:
+    - Don't use `--outdir` or `-o` here. Use the `out_dir` option instead.
+    - Without `--keep-logs` (or `--keep-intermediates` or `-k)`, you won't see
+      errors/warnings in the quickfix list when compilations finish.
+    - By default, `tectonic` cleans all auxiliary files (such as `.aux`,
+      `.toc`, etc.). If you omit the `--keep-logs` (or similar) options that
+      specify to keep these files, |:VimtexClean| and |<plug>(vimtex-clean)|
+      won't delete anything (as there is nothing to delete).
+
+*g:vimtex_compiler_arara*
+  This dictionary allows customization of the |vimtex-compiler-arara|
+  compiler. The values set by the user will take precedence over the default
+  values.
+
+  Default value: >vim

+
+  hooks ~
+    Same as |g:vimtex_compiler_latexmk| / `hooks`.
+
+*g:vimtex_compiler_generic*
+  This dictionary allows customization of the |vimtex-compiler-generic|
+  compiler. This compiler is, as the name hints, generic. It allows to specify
+  a custom command to run for compilation. As for the other compilers, the
+  configuration values set by the user will take precedence over the default
+  values.
+
+  Default value: >vim
+
+    let g:vimtex_compiler_generic = {
+        \ 'command' : '',
+        \ 'hooks' : [],
+        \}
+<
+  The default value shows which entries may be changed. Here the different
+  keys are explained in more detail:
+
+  command ~
+    This is the command to run to start compilation. This can be any command,
+    and the command is run from the project root.
+
+  hooks ~
+    Same as |g:vimtex_compiler_latexmk| / `hooks`.
+
+*g:vimtex_complete_enabled*
+  Use this option to disable/enable VimTeX completion.
+
+  Default value: 1
+
+*g:vimtex_complete_smart_case*
+  If enabled, then VimTeX will filter case sensitive if there is a capital
+  letter in the completion input. This is only relevant if
+  |g:vimtex_complete_ignore_case| is also enabled.
+
+  Default value: Same as your 'smartcase' value
+
+*g:vimtex_complete_ignore_case*
+  If enabled, then VimTeX will filter case insensitive.
+
+  Default value: Same as your 'ignorecase' value
+
+*g:vimtex_complete_close_braces*
+  This option controls whether to append a closing brace after a label or
+  a citation has been completed.
+
+  Default value: 0
+
+*g:vimtex_parser_bib_backend*
+  This option sets the desired default backend for parsing bibliographies.
+  This is used e.g. for gathering completion candidates. Possible values:
+
+    `bibtex`:   The fastest, but most "hacky" solution. Still, time has proved
+              that this works well!
+
+    `vim`:      The slowest but perhaps most robust solution, as it does not
+              require any external utilities.
+
+    `lua`:      A Lua implementation of the Vim backend. About as fast as the
+              `bibtex` parser, but this only works on Neovim.
+
+    `bibparse`: Also fast, but might be more robust.
+
+              Note: bibparse is an executable provided by the Perl package
+                    Text-BibTeX [0]. It should not be confused with the
+                    similarly named Python project [1]. The latter is
+                    deprecated in favor of GooseBib [2]. The Python projects
+                    bibparse and GooseBib are both based on the Python library
+                    `bibtexparser`.

+              Note: This requires that Python 3 is available to Vim/neovim
+                    (see |if_pyth| and |py3|) and that the `bibtexparser`
+                    Python module is installed and available.
+
+  Some people may want to conditionally change this option if a backend is
+  available. For example: >vim
+
+    if executable('bibparse')
+      let g:vimtex_parser_bib_backend = 'bibparse'
+    endif
+<
+  Default value:
+
+    Vim:    `bibtex`
+    Neovim: `lua`
+
+*g:vimtex_parser_cmd_separator_check*
+  This option specifies the policy for deciding whether successive groups of
+  `[opt]` and `{arg}` following a `\command` should be recognized as arguments
+  to that `\command`.
+
+  In fact, parsing a LaTeX command without additional knowledge is a hard
+  problem. When we read `\foo{bar}{baz}` — is `{baz}` going to be consumed as
+  an argument to `\foo`? The only way to know this is to read the definition
+  of the `\foo` command/macro.
+
+  A pragmatic choice when we write a parser, therefore, is to rely on some
+  heuristics and common practises. This will never be perfect, but it can be
+  good enough for practical use. In VimTeX, the core heuristics are that
+  a command will look like this: >
+
+    \foo<overlay>[[opt]{arg}]...
+    \begin{name}<overlay>[[opt]{arg}]...
+<
+  The parser greedily swallows as many groups of `[opt]` and `{arg}` as
+  possible as long as the function specified via this option returns true for
+  the text between successive such groups.
+
+  The default function will allow a line break and possibly white space on the
+  preceding line before a new group. E.g.: >latex
+
+    % command                number of args
+    % -------                --------------
+    \foo{bar}{baz}           % 2
+    \foo{bar} {baz}          % 1
+    \foo{bar}
+    {baz}                    % 2
+    \foo{bar}
+      {baz}                  % 2
+    \foo{bar}__
+      {baz}                  % 1 (_ indicates spaces)
+<
+  The option should be either the name of the function (a string) or
+  a |Funcref|. The function takes a single argument, which is the string
+  between successive `[opt]` and `{arg}` groups. It should return |v:true|
+  if the parser should continue and |v:false| if the parser should stop.
+
+  A user may want to change this behaviour e.g. to specify that all whitespace
+  should be allowed, including and up to a single newline: >vim
+
+    function! MyCmdSeparatorRule(separator_string)
+      return a:separator_string =~# '^\_s\+$'
+            \ && count(a:separator_string, "\n") < 2
+    endfunction
+
+    let g:vimtex_parser_cmd_separator_check = 'MyCmdSeparatorRule'
+<
+  Note: This option is relevant for any feature that relies on the parsing of
+        a command. This includes, but is not limited to the
+        |<plug>(vimtex-ac)| text object (|vimtex-text-objects|).
+
+  Note: |Funcref|s are only possible when it is used with neovim Lua
+        configuration, because in Vimscript, variable names must be
+        capitalized in order to point to |Funcref|s.
+
+  Default: `'vimtex#cmd#parser_separator_check'`
+
+*g:vimtex_bibliography_commands*
+  A list of command names for commands that include bibliography files. Each
+  list entry is interpreted as a pattern (very magic, see |/\v|) to match
+  a particular command name. This option may be useful if one defines custom
+  commands that includes bibliography files.
+
+  Default value: >
+      ['%(no)?bibliography', 'add%(bibresource|globalbib|sectionbib)']
+
+*g:vimtex_complete_bib*
+  This option is a dictionary for controlling the citation completion. The
+  keys each control a different thing as explained below.
+
+  simple ~
+    Default value: 0
+    If zero, then the cite completion is "smart", i.e. not simple. This
+    behaviour is described in more detail in |vimtex-complete-cites|.
+
+    Note: It is usually better to use the "simple" mode if you use an
+          autocomplete plugin (|vimtex-complete-auto|).
+
+                                          *g:vimtex_complete_bib.match_str_fmt*
+  match_str_fmt ~
+    Default value: `'@key [@type] @author_all (@year), "@title"'`
+    The format used for the match string for bib completion candidates. That
+    is, the string that the smart mode candidate matching is matched against.
+    See |vimtex-complete-cites| for more info. The following keys may be used
+    to define the string: >
+
+      @author_all    Full author list
+      @author_short  Shortened author list
+      @key           The bibtex key
+      @title         Title
+      @type          Type of entry
+      @year          Publication year
+<
+    Since the author list can be large, the `@author_all` is truncated to 20
+    characters. This can be modified with the `auth_len` key (see below).
+
+  menu_fmt ~
+    Default value: `'[@type] @author_short (@year), "@title"'`
+    The format used for the `menu` entry for bib completion candidates (see
+    |complete-items|). If the key is set to an empty string, then the `menu`
+    entry is not added to the completion candidates. See the description of
+    `match_str_fmt` for the allowed keys.
+
+  info_fmt ~
+    Default value: `"TITLE: @title\nAUTHOR: @author_all\nYEAR: @year"`
+    The format used for the `info` entry for bib completion candidates (see
+    |complete-items|). See the description of `match_str_fmt` for the allowed
+    keys.
+
+  abbr_fmt ~
+    Default value: `''`
+    The format used for the `abbr` entry for bib completion candidates (see
+    |complete-items|). See the description of `match_str_fmt` for the allowed
+    keys.
+
+  auth_len ~
+    Default value: 20
+    Truncation length for author list with the `@author_all` format key in the
+    format strings for `match_str_fmt`, `menu_fmt`, and `abbr_fmt`.
+
+  custom_patterns ~
+    Default value: []
+    List of custom trigger patterns that may be used to allow completion for
+    e.g. custom macros.
+
+  If one wants to overwrite one of the keys, e.g. the `simple` entry, one can
+  do: >vim
+
+    let g:vimtex_complete_bib = { 'simple': 1 }
+<
+  This does not modify the other keys and their default values.
+
+*g:vimtex_complete_ref*
+  This option is a dictionary for controlling the label completion. The
+  keys each control a different thing:
+
+  custom_patterns ~
+    Default value: []
+    List of custom trigger patterns that may be used to allow completion for
+    e.g. custom macros.
+
+  For example, if one has defined the command `\figref`, one could add following
+  custom pattern >vim
+
+     let g:vimtex_complete_ref = {
+        \ 'custom_patterns': ['\\figref\*\?{[^}]*$']
+        \ }
+
+*g:vimtex_context_pdf_viewer*
+  Specify PDF viewer to use to open PDF files with the |vimtex-context-menu|, for
+  instance for citations with the `file` key (see |vimtex-context-citation|).
+
+  The default value is based on the |vimtex-view| and is determined as follows:
+
+    * If |g:vimtex_view_method| is not `general`, then the specified viewer is
+      used. However, the viewer will by default start without any of the
+      regular options.
+
+    * Else fall back to the value of |g:vimtex_view_general_viewer|.
+
+*g:vimtex_delim_list*
+  A dictionary that defines the pairs of delimiters that are recognized by
+  VimTeX for various commands and functions. The dictionary contains 5 sub
+  dictionaries:
+
+    `env_tex`     Pairs of environment delimiters in normal TeX mode
+    `env_math`    Pairs of special math environment delimiters
+    `delim_tex`   Pairs of delimiters in normal TeX mode
+    `delim_math`  Pairs of delimiters in math mode
+    `mods`        Pairs of modifiers for math mode delimiters
+
+  Each entry is a dictionary with the following format: >
+
+    {
+    \ 'name' : [
+    \   ['\(', '\)'],
+    \   ['\[', '\]'],
+    \   ['$$', '$$'],
+    \   ['$', '$'],
+    \ ],
+    \ 're' : [
+    \   ['\\(', '\\)'],
+    \   ['\\\@<!\\\[', '\\\]'],
+    \   ['\$\$', '\$\$'],
+    \   ['\$', '\$'],
+    \ ],
+    \}
+<
+  Here the `name` entry is a list of delimiter pairs as they are typed, and the
+  `re` entry is a corresponding list of regexes that matches the delimiters.
+
+  The default value should generally suffice for most people. If one wants to
+  overwrite one of the main entries, e.g. the `mods` entry, one can do
+  something like this: >vim
+
+    let g:vimtex_delim_list = {
+          \ 'mods' : {
+          \   'name' : [ "..." ],
+          \ }
+          \}
+<
+  Here the `re` entry was not provided, in which case it will be automatically
+  generated based on the `name` entry. The remaining four entries will remain
+  the default value.
+
+  Some people may be interested in adding support for e.g. german or french
+  quotation marks. These may be added by extending the default `delim_tex`
+  entries, like this: >vim
+
+    let g:vimtex_delim_list = {
+        \ 'delim_tex' : {
+        \   'name' : [
+        \     ['[', ']'],
+        \     ['{', '}'],
+        \     ['\glq', '\grq'],
+        \     ['\glqq', '\grqq'],
+        \     ['\flq', '\frq'],
+        \     ['\flqq', '\frqq'],
+        \    ]
+        \  }
+        \}
+<
+                                                         *g:vimtex#delim#lists*
+                                                         *g:vimtex#delim#re*
+  Note: This option is parsed on plugin initialization into a new variable,
+        |g:vimtex#delim#lists| where the `re` entries are added and that also
+        contains some combinations such as `tex_all`, `delim_all`, and `all`.
+        Further, the option is also used as a basis for the variable
+        |g:vimtex#delim#re|, which contains full regexes for matching opening
+        and/or closing delimiters of the desired type.
+
+  Default value: See `s:init_delim_lists()` in `/autoload/vimtex/delim.vim`.
+
+*g:vimtex_delim_toggle_mod_list*
+  Defines a list of delimiter modifiers to toggle through using the maps:
+
+    |<plug>(vimtex-delim-toggle-modifier)|
+    |<plug>(vimtex-delim-toggle-modifier-reverse)|
+
+  The list must be a subset of the `mods` entry of |g:vimtex_delim_list|,
+  otherwise the toggle will not work properly.  Thus, if one wants to toggle
+  non-standard delimiters, then one must also update the above option.
+
+  Example 1: to toggle between no modifiers, the `\left/\right` pair, and the
+  `\mleft/\mright` pair, one may use the following options: >vim
+
+    let g:vimtex_delim_list = {'mods' : {}}
+    let g:vimtex_delim_list.mods.name = [
+          \ ['\left', '\right'],
+          \ ['\mleft', '\mright'],
+          \ ['\bigl', '\bigr'],
+          \ ['\Bigl', '\Bigr'],
+          \ ['\biggl', '\biggr'],
+          \ ['\Biggl', '\Biggr'],
+          \ ['\big', '\big'],
+          \ ['\Big', '\Big'],
+          \ ['\bigg', '\bigg'],
+          \ ['\Bigg', '\Bigg'],
+          \]
+    let g:vimtex_delim_toggle_mod_list = [
+      \ ['\left', '\right'],
+      \ ['\mleft', '\mright'],
+      \]
+<
+  Example 2: to step through no modifiers, and the pairs `\bigl/\bigr`,
+  `\Bigl/\Bigr`, `\biggl/\biggr`, and `\Biggl/\Biggr`, one may use: >vim
+
+    let g:vimtex_delim_toggle_mod_list = [
+      \ ['\bigl', '\bigr'],
+      \ ['\Bigl', '\Bigr'],
+      \ ['\biggl', '\biggr'],
+      \ ['\Biggl', '\Biggr'],
+      \]
+<
+  Default value: `[['\left', '\right']]`
+
+*g:vimtex_delim_timeout*
+*g:vimtex_delim_insert_timeout*
+  Timeout (in milliseconds) when searching for matching delimiters. It is used
+  for the {timeout} argument of |search()|-like function calls. If the option
+  is increased it will make the matching more accurate, at the expense of
+  potential lags. The default value should work well for most people.
+
+  Default values: 300, 60 (respectively)
+
+*g:vimtex_delim_stopline*
+  A tolerance for the number of lines to search for matching delimiters in
+  each direction. It is used in an expression for the {stopline} argument of
+  |search()| function calls. If the option is increased it will make the
+  matching more accurate, at the expense of potential lags. The default value
+  should work well for most people.
+
+  Default value: 500
+
+*g:vimtex_doc_enabled*
+  Use this option to disable features related to |vimtex-latexdoc|.
+
+  Default value: 1
+
+*g:vimtex_doc_confirm_single*
+  When enabled (set to 1 or |v:true|), then VimTeX will open the specified
+  documentation only after a confirmation prompt such as: >
+
+    Open documentation for usepackage: foobar? [y]es/[n]o
+<
+  Thus, one may disable this option (set to 0 or |v:false|) to avoid the
+  confirmation and open directly. Note that this is only relevant when there
+  is only a single recognized documentation source.
+
+  Default value: |v:true|
+
+*g:vimtex_doc_handlers*
+  With this option, one may specify a list of custom documentation handlers.
+  The following pre-made handlers are available:
+
+    `'vimtex#doc#handler#texdoc'`  Open documentation with local `texdoc`.
+    Fallback                     Open documentation online through
+                                 http://texdoc.net/pkg/packagename.
+
+  To use the local `texdoc`, set: >vim
+
+    let g:vimtex_doc_handlers = ['vimtex#doc#handlers#texdoc']
+<
+  A handler is a function that takes a single |Dict| argument with the
+  following keys:
+
+    type ~
+      One of `documentclass`, `usepackage`, `command` or `word`.
+
+    candidates ~
+      A list of detected packages (for the types `command` and `usepackage`,
+      this list may be larger than 1.
+
+    selected ~
+      The currently selected entry. This is the package name that will
+      ultimately be passed to the lookup function.
+
+    name ~
+      If the type is `command`, this is the name of the command. Else it is
+      not defined.
+
+  Each handler in the list will be tried until a handler provides a return
+  value of 1 or |v:true|. One may thus add handlers that only makes minor
+  modifications of the context and passes it on to the next handler.
+
+  The context may have multiple candidates and the handlers are applied before
+  any internal selection is made. Thus the `selected` key may be not defined.
+  This allows the handler to perform the selection itself. One may manually
+  call the selection function `vimtex#doc#make_selection` to get a simple
+  selection menu.
+
+  The following shows a generic example of how to write a custom handler: >vim
+
+    let g:vimtex_doc_handlers = ['MyHandler']
+
+    function! MyHandler(context)
+      call vimtex#doc#make_selection(a:context)
+      if empty(a:context.selected) | return 0 | endif
+
+      execute '!myhandler' a:context.selected '&'
+      return 1
+    endfunction
+<
+  Default value: []
+
+*g:vimtex_echo_verbose_input*
+  For the set of operator mappings that change a surrounding type [0],
+  VimTeX by default prints some information about what you are doing while
+  waiting for user input. For advanced/experienced users, one will not need
+  this info and can get a slightly cleaner UI by disabling this feature (set
+  the option 0).
+
+  Default value: 1
+
+  [0]: This affects the following mappings:
+    |<plug>(vimtex-env-change)|        (default map: `cse`)
+    |<plug>(vimtex-env-change-math)|   (default map: `cs$`)
+    |<plug>(vimtex-cmd-change)|        (default map: `csc`)
+    |<plug>(vimtex-delim-change-math)| (default map: `csd`)
+
+*g:vimtex_env_change_autofill*
+  If enabled, the current environment value is used as a default input for
+  |<plug>(vimtex-env-change)| and |<plug>(vimtex-env-change-math)|. Some users
+  may find this useful in order to quickly change from things like `align` to
+  `aligned`.
+
+  Note: If enabled, one may erase the autofilled content with |c_CTRL-U| (i.e.
+        `<c-u>`).
+
+  Default: 0
+
+*g:vimtex_env_toggle_math_map*
+  Specify toggle map for |<plug>(vimtex-env-toggle-math)|. You can use this to
+  change the desired toggle sequence.
+
+  Default value: >vim
+
+    let g:vimtex_env_toggle_math_map = {
+          \ '$': '\[',
+          \ '\[': 'equation',
+          \ '$$': '\[',
+          \ '\(': '$',
+          \}
+
+*g:vimtex_fold_enabled*
+  Use this option to enable folding, which means VimTeX will enable the
+  following options for LaTeX files: >vim
+
+    setlocal foldmethod=expr
+    setlocal foldexpr=vimtex#fold#level(v:lnum)
+    setlocal foldtext=vimtex#fold#text()
+<
+  More detailed info can be found in the section |vimtex-folding|.
+
+  Default value: 0
+
+*g:vimtex_fold_manual*
+  With this option enabled, VimTeX uses |fold-manual| as the main
+  |foldmethod|.  It still uses the |foldexpr| function to compute the fold
+  levels, but it only computes the fold levels on demand, see
+  |:VimtexRefreshFolds| and |vimtex-zx|.
+
+  The reasoning behind this option is that the |fold-expr| method of folding
+  may sometimes be slow, e.g. for long lines and large files. |fold-manual| is
+  very fast.
+
+  An alternative to this method of speeding up is to use a dedicated plugin
+  for optimizing the fold functionality, see e.g.
+  https://github.com/Konfekt/FastFold.
+
+  Default value: 0
+
+*g:vimtex_fold_levelmarker*
+
+  Use custom section symbol for folding.
+
+  Default value: `'*'`
+
+*g:vimtex_fold_types*
+*g:vimtex_fold_types_defaults*
+  This is a dictionary where each key configures the corresponding fold type.
+  One may disable the fold types by setting the key `enabled` to 0. If a type
+  can be configured with a list of patterns or similar, the patterns assume
+  that one uses very magic regexes (see |\v|).
+
+  Each entry in |g:vimtex_fold_types| is combined with the corresponding entry
+  of |g:vimtex_fold_types_defaults|. If there are conflicting entries, then
+  |g:vimtex_fold_types| take precedence. This way, it is easy to customize
+  various fold types without touching those that can stay with default
+  configuration.
+
+  The available fold types (and keys) are listed below, and the default
+  configurations are listed at the bottom.
+
+    <preamble>          Fold the preamble.
+
+    <sections>          Fold sections and parts of documents. Can be
+                        configured with the following extra keys:
+                        - `parse_levels`: Whether to use detailed parsing to
+                                        set fold text levels similar to how
+                                        they are displayed in |vimtex-toc|.
+                                        Disabled by default, because it uses
+                                        more resources and may be slow.
+                        - `sections`:     List of sections that should be folded.
+                        - `parts`:        List of parts that should be folded.
+
+                        When a LaTeX document is opened, the document is
+                        parsed in order to define the highest fold level based
+                        on which parts (such as frontmatter, backmatter, and
+                        appendix) and section types (parts, chapter, section,
+                        etc.) are present. This parsing is done automatically
+                        every time the folds are recomputed, if there are any
+                        changes to the file.
+
+                        The fold function also recognizes "fake" sections.
+                        That is, it parses comments similar to: >
+
+                          % Fakepart title
+                          % Fakechapter title
+                          % Fakesection title
+                          % Fakesubsection title
+<
+                        The fake sections are folded at the same level as the
+                        corresponding "real" sections. The fold title is the
+                        provided title with the `Fake...` part prepended.
+
+    <comment_pkg>       Fold `\begin{comments} ... \end{comments}` and disable
+                        folding inside the environment.
+
+    <comments>          Fold multiline comments. This is disabled by default.
+
+    <markers>           Fold on vim-style markers inside comments, that is,
+                        pairs of e.g. `{{{` and `}}}` (the default markers).
+                        |regex| patterns for the opening and closing markers
+                        may be customized with the keys:
+                        - `open`
+                        - `close`
+
+                        Note: Patterns are only searched inside comments!
+
+    <envs>              Fold environments.
+                        Can be further configured with a blacklist and
+                        whitelist of environments to be folded.
+
+                        Note: The `document` environment will never be folded.
+
+    <env_options>       This fold type allows to fold the `\begin` command if
+                        it contains a long optional argument. Consider the
+                        following example: >
+
+                          \begin{axis}[    --->    \begin{axis}[...]
+                              width=6cm,
+                              height=8cm,
+                              ...,
+                          ]
+<
+                        Here the `axis` environment must not be otherwise
+                        folded through the <envs> fold type.
+
+    <items>             `\item` blocks in itemize like environments. The
+                        recognized environments are the same as specified by
+                        |g:vimtex_indent_lists|.
+
+    <cmd_single>        Fold long commands with a single argument. E.g.: >
+
+                          \hypersetup{    --->    \hypersetup{...}
+                            option 1,
+                            ...,
+                            option n
+                            }
+<
+    <cmd_single_opt>    Fold commands that opens with a single long optional
+                        argument that is followed by a short "real" argument.
+                        E.g.: >
+
+                          \usepackage[    --->    \usepackage[...]{name}
+                            option 1,
+                            ...,
+                            option n
+                            ]{name}
+<
+    <cmd_multi>         Fold commands that start with a short regular argument
+                        and continue with long optional and/or regular
+                        arguments. E.g.: >
+
+                          \newcommand{\xx}[3]{    --->    \newcommand{\xx} ...
+                            Hello #1, #2, and #3.
+                          }
+<
+    <cmd_addplot>       Folding of the `\addplot` series of commands from the
+                        `pgfplots` package. E.g.: >
+
+                          \addplot+[] table[] {    --->    \addplot+[] table[] {...};
+                            table data
+                          };

+
+*g:vimtex_fold_bib_enabled*
+  Use this option to enable/disable folding in `.bib` files. When enabled,
+  VimTeX will set the following options for `.bib` files: >vim
+
+    setlocal foldmethod=expr
+    setlocal foldexpr=vimtex#fold#bib#level(v:lnum)
+    setlocal foldtext=vimtex#fold#bib#text()
+<
+  Note: The default value is the same as |g:vimtex_fold_enabled|. Thus, it
+        suffices to enabled folds for tex files to also enable for bib files.
+        But if you want to enable in tex files but keep bib folding disabled,
+        then you must set this option to 0 or |v:false|.
+
+  Default value: |g:vimtex_fold_enabled|
+
+*g:vimtex_fold_bib_max_key_width*
+  This option is used to specify a length to truncate identifiers (e.g.
+  `@article{Key}`) to, in the foldtext for bib files. The default of 0
+  indicates no truncation, i.e. VimTeX will parse the bib file to determine
+  the longest such identifier and align all foldtext titles such that they
+  come after the identifiers.
+
+  If you have a handful of cite keys that are exceptionally long, setting this
+  manually may be useful as it makes sure that there is some space for the
+  titles in the foldtext.
+
+  Default value: 0
+
+*g:vimtex_format_enabled*
+  If enabled, VimTeX uses a custom |formatexpr| that should handle inline
+  comments and environments. That is, if it is enabled, comments at end of
+  lines will not be joined with the |gq| command, and environments like
+  `equation` will not be joined/changed.
+
+  Default value: 0
+
+*g:vimtex_format_border_begin*
+*g:vimtex_format_border_end*
+  Regular expressions that define the "borders" of a region that should be
+  formatted. The defaults should be more or less OK for most people, but some
+  people may be interested in adjusting to handle more complex LaTeX code.
+
+  Default value: See source in `/autoload/vimtex/options.vim`
+
+*g:vimtex_grammar_textidote*
+  This option is used to configure the `textidote` grammar and document checker,
+  see |vimtex-grammar-textidote|. It is a dictionary with the following keys
+
+    jar ~
+      The path to `textidote.jar`. This key must be defined if you want to use
+      the TeXtidote wrapper! Please note that if one installs `textidote` with
+      a package manager e.g. in some common Linux distributions, the `.jar`
+      file might be missing. If so, it should be possible to download it
+      manually.
+
+    args ~
+       Specify arguments to be passed to the TeXtidote grammar checker.
+
+  Default: >vim
+
+      let g:vimtex_grammar_textidote = {
+            \ 'jar': '',
+            \ 'args': '',
+            \}
+
+*g:vimtex_grammar_vlty*
+  This option is used to configure the `vlty` grammar checker. This checker
+  relies on the Python package `YaLafi` in combination with the proofreading
+  software `LanguageTool` (see |vimtex-grammar-vlty| for more details). The
+  option is a dictionary with the following keys :
+
+    lt_directory ~
+      Path to the `LanguageTool` software, if installed manually.
+
+    lt_command ~
+      Name of `LanguageTool` executable, if installed via package manager. Note
+      that this has precedence over `lt_directory`!
+
+    lt_disable ~
+    lt_enable ~
+    lt_disablecategories ~
+    lt_enablecategories ~
+      Options for `LanguageTool` that control application of rules and rule
+      categories. For more info, see:
+      http://wiki.languagetool.org/command-line-options
+
+    server ~
+      Specify whether an HTTP server should be used. This may be faster for
+      short texts. Possible values are:
+
+      `no`    Do not use a server.
+      `my`    Use a local `LanguageTool` server. If not yet running, it is
+              started.
+      `lt`    Contact the Web server provided by `LanguageTool`. In this case,
+            no local installation is necessary. Please see the following page
+            for conditions and restrictions:
+            https://dev.languagetool.org/public-http-api
+
+    shell_options ~
+      Pass additional options to `YaLafi`, e.g., `--equation-punctuation displ`;
+      for more info, see:
+      https://github.com/torik42/YaLafi
+
+    show_suggestions ~
+      If set to 1, then `LanguageTool's` replacement suggestions are included
+      in the |quickfix| or |location-list| messages.
+
+    encoding ~
+      Encoding of the (La)TeX source file. For default value `auto`, the
+      encoding is taken from |fileencoding| or |encoding|.
+
+  Default: >vim
+
+      let g:vimtex_grammar_vlty = {
+            \ 'lt_directory': '~/lib/LanguageTool',
+            \ 'lt_command': '',
+            \ 'lt_disable': 'WHITESPACE_RULE',
+            \ 'lt_enable': '',
+            \ 'lt_disablecategories': '',
+            \ 'lt_enablecategories': '',
+            \ 'server': 'no',
+            \ 'shell_options': '',
+            \ 'show_suggestions': 0,
+            \ 'encoding': 'auto',
+            \}
+
+*g:vimtex_imaps_enabled*
+  Use this option to disable/enable the insert mode mappings.
+
+  Default value: 1
+
+*g:vimtex_imaps_leader*
+  The default leader key for insert mode mappings.
+
+  Default value: "`"
+
+*g:vimtex_imaps_disabled*
+  A list of mappings to disable. That is, any left-hand side that matches
+  a string in this list will not be mapped to its corresponding right-hand
+  side. This may be used to selectively disable one or more from the default
+  list of mappings.
+
+  Default value: []
+
+*g:vimtex_imaps_list*
+  The list of mappings to generate on start up. The list of activated mappings
+  can be viewed with |:VimtexImapsList|.
+
+  Default value: See `/autoload/vimtex/options.vim` (it's a long list)
+
+*g:vimtex_include_indicators*
+  VimTeX will recognize included files for a lot of different purposes. Most
+  of these come from e.g. `\input{file}` or `\include{file}`. This option
+  allows to add more commands that are used to include files, e.g. custom
+  macros.
+
+  Note: This option is read during initialization of VimTeX, and so it must be
+        set early. I.e., it can not be set in `after/ftplugin/tex.vim`.
+
+  Default value: `['input', 'include', 'includeonly']`
+
+*g:vimtex_include_search_enabled*
+  VimTeX sets 'includeexpr' to recognize included files. If a file isn't found
+  in the current directory, VimTeX uses `kpsewhich` to search for it in the
+  system TeX distribution. If the 'complete' option includes "i", invoking
+  keyword completion with |i_CTRL-N| will search included files for completion
+  possibilities. In this case, there may be a lot of calls to `kpsewhich`
+  while scanning for included files during the first invocation of keyword
+  completion, and this may introduce a significant delay. Subsequent keyword
+  completions should be faster, as the calls to `kpsewhich` are cached.
+
+  This option allows to disable searching for included files with `kpsewhich`,
+  and with that prevent the above explained delay.
+
+  Default value: 1
+
+*g:vimtex_indent_enabled*
+  Use this option to disable/enable VimTeX indentation.
+
+  Default value: 1
+
+*g:vimtex_indent_bib_enabled*
+  Use this option to disable/enable VimTeX indentation of bibliography files.
+
+  Default value: 1
+
+*g:vimtex_indent_conditionals*
+  This is a dictionary that defines regexes for indenting conditionals. Set it
+  to an empty dictionary to disable this type of indentation.
+
+  Default value: >vim
+    let g:vimtex_indent_conditionals = {
+          \ 'open': '\v%(\\newif)@<!\\if%(f>|field|name|numequal|thenelse|toggle)@!',
+          \ 'else': '\\else\>',
+          \ 'close': '\\fi\>',
+          \}
+
+*g:vimtex_indent_delims*
+  A dictionary that specifies how to indent delimiters. The dictionary has
+  four keys:
+
+    open ~
+      List of regexes for opening delimiters that should add indents.
+
+    close ~
+      List of regexes for closing delimiters that should reduce indents.
+
+    close_indented ~
+      Set this to 1 if you want the line with the closing delimiter to stay
+      indented.
+
+    include_modified_math ~
+      Set this to 0 if you do not want modified math delimiters such as
+      `\left(` and `\right)` to add/reduce indents.
+
+  Note: VimTeX does not allow indents for parentheses only in math mode or any
+        similar kind of context aware delimiter indents.
+
+  Note: If one of the keys of the dictionary is not specified, the default
+        value is assumed.
+
+  Default value: >vim
+    let g:vimtex_indent_delims = {
+          \ 'open' : ['{'],
+          \ 'close' : ['}'],
+          \ 'close_indented' : 0,
+          \ 'include_modified_math' : 1,
+          \}
+
+*g:vimtex_indent_ignored_envs*
+  List of environments that should not add/reduce indentation.
+
+  Note: Each item is interpreted as a regular expression that is combined into
+        very magic regexes like `\v<%(document|...)>`, see |/\v|.
+
+  Default value: ['document']
+
+*g:vimtex_indent_lists*
+  List of environments that act like lists with `\item` entries.
+
+  Note: Each item is interpreted as a regular expression that is combined into
+        regexes like `\\begin{\%(itemize|description|...\)`.
+
+  Default value: [
+      \ 'itemize',
+      \ 'description',
+      \ 'enumerate',
+      \ 'thebibliography',
+      \]
+
+*g:vimtex_indent_on_ampersands*
+  By default, VimTeX will align on `leading` ampersands e.g. in math aligned
+  environments or in tabular environments. If this feature is not wanted it
+  may be disabled through this option.
+
+  Note: To get a more advanced tabular like alignment feature, you may be
+        interested in something like |vim-easy-align|:
+        https://github.com/junegunn/vim-easy-align
+
+  Default value: 1
+
+*g:vimtex_indent_tikz_commands*
+  Use this option to disable/enable VimTeX indentation of multi-line commands
+  in TikZ pictures.
+
+  Default value: 1
+
+*g:vimtex_mappings_enabled*
+  Control whether or not to load the default mappings.
+
+  Default value: 1
+
+*g:vimtex_mappings_disable*
+  A dictionary that can be used to disable specific mappings.  The dictionary
+  keys are the mapping modes, and the values are lists of default mappings
+  that should be disabled.  The following example will ensure that the default
+  `tse` and `tsd` mappings are disabled: >vim
+
+    let g:vimtex_mappings_disable = {
+        \ 'n': ['tse', 'tsd'],
+        \ 'x': ['tsd'],
+        \}
+<
+  Default value: {}
+
+*g:vimtex_mappings_override_existing*
+  Control behaviour on mapping conflicts, in particular whether or not to
+  override pre-existing mappings. By default, VimTeX does not override existing
+  mappings. If this option is enabled, then VimTeX will override existing
+  mappings on conflict.
+
+  Default value: 0
+
+*g:vimtex_mappings_prefix*
+  The default prefix for `<localleader>` based mappings.
+
+  Default value: `'<localleader>l'`
+
+*g:vimtex_matchparen_enabled*
+  Enable highlighting of matching delimiters.
+
+  Note: This is an improved version of |matchparen|. It should be possible to
+        keep |matchparen| activated, which matches delimiters listed in
+        'matchpairs'. The VimTeX specific version will also match LaTeX
+        specific delimiters, which is not possible with |matchparen|.
+
+  Note: If you think this feature is slow, see |vimtex-faq-slow-matchparen|.
+
+  Default value: 1
+
+*g:vimtex_motion_enabled*
+  This option enables the motion mappings, see |vimtex-motions|. It also
+  enables the highlighting of matching delimiters.
+
+  Default value: 1
+
+*g:vimtex_lint_chktex_ignore_warnings*
+  A string variable of options to pass for `chktex` to specify to ignore
+  certain warning messages.
+
+  Default value: `'-n1 -n3 -n8 -n25 -n36'`
+
+*g:vimtex_lint_chktex_parameters*
+  A string variable of parameters to pass to `chktex`.
+
+  VimTeX will look for a configuration file at `$XDG_CONFIG_HOME/chktexrc`, or
+  `$HOME/.config/chktexrc` if `$XDG_CONFIG_HOME` is undefined. If this file
+  exists, it is specified by default with `--localrc=...`.
+
+  Default value: `'--localrc=PATH/chktexrc'` or `''` (see above)
+
+*g:vimtex_log_ignore*
+  A list of regexes to filter info, warning, and error messages. If a logged
+  message matches any of the regexes in this list, the message will not be
+  printed to screen.
+
+  Note: All messages may still be viewed with |:VimtexLog|.
+
+  Default: []
+
+*g:vimtex_log_verbose*
+  Whether or not to print messages to screen. Should generally be on, but may
+  be turned off e.g. for debugging or testing purposes.
+
+  Default: 1
+
+*g:vimtex_quickfix_enabled*
+  Use this option to disable/enable the quickfix integration.
+
+  Default value: 1
+
+*g:vimtex_quickfix_method*
+  This option sets the quickfix method. The following methods are available:
+
+  latexlog ~
+    This is the standard method which parses the normal LaTeX output.
+
+  pplatex ~
+    Uses `pplatex` (https://github.com/stefanhepp/pplatex) to parse the LaTeX
+    output file. `pplatex` is a command line utility used to prettify the
+    output of the LaTeX compiler.
+
+  pulp ~
+    Uses `pulp` (https://github.com/dmwit/pulp) to parse the LaTeX output
+    file, similar to `pplatex`.
+
+  Note: `pplatex` and `pulp` require that `-file-line-error` is NOT passed to the LaTeX
+  compiler. |g:vimtex_compiler_latexmk| will be updated automatically if one
+  uses `latexmk` through VimTeX. However, if one uses other compiler
+  methods, either through VimTeX (see |g:vimtex_compiler_method|) or
+  externally, this requirement must be ensured by the user.
+
+  Default value: `'latexlog'`
+
+*g:vimtex_quickfix_blgparser*
+  This option controls the parsing of `blg` log files (created by bibtex or
+  biber) for warnings and errors.  The option is a dictionary with the
+  following keys:
+
+    disable ~
+      Disable the parsing of `blg` entries.
+
+  Default value: {}
+
+*g:vimtex_quickfix_autojump*
+  This option controls if vim should automatically jump to the first error
+  whenever the |quickfix| window is opened.
+
+  Note: This option does not go well with continuous compilation and
+        callbacks, since the callbacks will open the quickfix window if there
+        are errors.  Thus I recommend to keep it disabled for continuous
+        compilation, and rather enable it if one prefers single shot
+        compilations.
+
+  Default value: 0
+
+*g:vimtex_quickfix_ignore_filters*
+  This option allows to provide a list of |regular-expression|s for filtering
+  out undesired errors and warnings. This works regardless of which quickfix
+  method is enabled.
+
+  The following example will ignore any messages that match "Marginpar on
+  page": >vim
+
+    " Disable custom warnings based on regexp
+    let g:vimtex_quickfix_ignore_filters = [
+          \ 'Marginpar on page',
+          \]
+<
+  Default: []
+
+*g:vimtex_quickfix_mode*
+  This option controls the behaviour of the |quickfix| window in case errors
+  and/or warnings are found.  The recognized options are:
+
+  Value  Effect ~
+  0      The quickfix window is never opened/closed automatically.
+  1      The quickfix window is opened automatically when there are errors,
+         and it becomes the active window.
+  2      The quickfix window is opened automatically when there are errors,
+         but it does not become the active window.
+
+  Note: The quickfix window will only be opened automatically if the compiler
+        is set to `continuous` mode and has `callbacks` enabled, or if
+        `continuous` mode is disabled.
+
+  Default value: 2
+
+*g:vimtex_quickfix_autoclose_after_keystrokes*
+  If set to value greater than zero, then the quickfix window will close after
+  this number of motions (i.e. |CursorMoved| and |CursorMovedI| events). This
+  is most useful if one sets |g:vimtex_quickfix_mode| to 2, in which case this
+  option allows one to continue editing and removing the distraction of the
+  quickfix window automatically.
+
+  Note: The count is reset when the quickfix window is entered.
+
+  Default value: 0
+
+*g:vimtex_quickfix_open_on_warning*
+  Control whether or not to automatically open the |quickfix| window in case
+  there are warning messages and no error messages.
+
+  Default value: 1
+
+*g:vimtex_subfile_start_local*
+  This option allows to specify that one should start with the local file for
+  subfile'd documents instead of the main project file. See |vimtex-subfiles|
+  for further info.
+
+  Default value: 0.
+
+*g:vimtex_syntax_enabled*
+  Use this option to disable/enable syntax highlighting as provided by VimTeX.
+
+  Default value: 1.
+
+*g:vimtex_syntax_conceal*
+  A dictionary for specifying which core conceal features to activate. This
+  mostly implies concealing particular elements with a replacement unicode
+  character. For more info, see |vimtex-syntax-conceal|. To disable all
+  conceal features in one go, use |g:vimtex_syntax_conceal_disable|.
+
+  The following keys are available:
+
+    accents ~
+      Conceal accented characters, e.g. `\^a` --> `â`.
+
+    ligatures ~
+      Conceal ligatures such as `\aa` --> `å` and `''` --> `“`.
+
+    cites ~
+      Conceal LaTeX cite commands such as `\citet[...]{ref00}`. The conceal
+      style is specified by |g:vimtex_syntax_conceal_cites|.
+
+    fancy ~
+      Some extra fancy replacements, e.g. `\item` --> ○.
+
+    spacing ~
+      Conceal spacing commands such as `\quad` and `\hspace{1em}` in both
+      normal mode and math mode.
+
+    greek ~
+      Replace TeX greek letter commands into the equivalent unicode greek
+      letter.
+
+    math_bounds ~
+      Conceal the TeX math bounds characters: pairs of `$` and `$$`, `\(` ...
+      `\)`, and `\[` ... `\]`.
+
+    math_delimiters ~
+      Replace possibly modified math delimiters with a single unicode
+      letter. Modified means delimiters prepended with e.g. `\left` or
+      `\bigl`. As an example, this will perform the replacement
+
+        `\Biggl\langle ... \Biggr\rangle` --> `〈 ... 〉`
+
+    math_fracs ~
+      Replace some simple fractions like `\frac 1 2` --> ½.
+
+    math_super_sub ~
+      Replace simple math super and sub operators, e.g. `x^2` --> `x²`.
+
+    math_symbols ~
+      Replace various math symbol commands to an equivalent unicode character.
+      This includes quite a lot of replacements, so be warned!
+
+    sections ~
+      Conceal `\(sub)*section` commands. The titles are replaced with Markdown
+      style ATX headers, e.g.:
+
+        `\section{Test}`    --> `# Test`
+        `\subsection{Test}` --> `## Test`
+
+    styles ~
+      Conceal the LaTeX command "boundaries" for italicized and bolded style
+      commands, i.e. `\emph`, `\textit`, and `\textbf`. This means that one
+      will see something like:
+
+        `\emph{text here}` --> `text here`
+
+  Default value: >vim

+*g:vimtex_syntax_conceal_disable*
+  This option allows to disable all conceal features at once. For more fine
+  tuned control, use |g:vimtex_syntax_conceal| and |g:vimtex_syntax_packages|.
+
+  Default value: 0
+
+*g:vimtex_syntax_conceal_cites*
+  A simple dictionary to control how citation conceal should work. It has
+  three keys:
+
+    type ~
+      Specify the type of concealment. There are two options, and the
+      difference is best explained by example:
+
+        Value       LaTeX             Concealed
+        -----       -----             ---------
+        `'icon'`      `\cite{Knuth1981}`  `📖`
+        `'brackets'`  `\cite{Knuth1981}`  `[Knuth1981]`
+
+    icon ~
+      Specify an icon for `icon` conceal. This must be a single (possibly
+      multibyte) character.
+
+    verbose ~
+      Specify how much to conceal in bracket mode (`type` set to `'bracket'`).
+      The following table shows how the concealed result depending on the
+      `'verbose'` value for `\cite[Figure 1]{Knuth1981}`:
+
+        Value    Concealed
+        -----    ---------
+        |v:true|   `[Figure 1][Knuth1981]`
+        |v:false|  `[Knuth1981]`
+
+  Default value: >vim
+
+    let g:vimtex_syntax_conceal_cites = {
+          \ 'type': 'brackets',
+          \ 'icon': '📖',
+          \ 'verbose': v:true,
+          \}
+
+*g:vimtex_syntax_custom_cmds*
+  A list of "simple" commands for which to apply custom styling. This includes
+  bolded or italicized text arguments, conceals, or similar - see the below
+  keys. Each command is expected to be of the following type: >
+
+    \cmdname[optional]{argument}
+<
+  It is important to be aware that these customizations will be applied on top
+  of the existing syntax rules. These may therefore override both the core
+  syntax rules and extensions from syntax packages.
+
+  Each element in the list must be a dictionary with the following keys:
+
+    name ~
+      Default: Undefined (REQUIRED)
+      The command to highlight (`cmdname`). This is also for defining the
+      syntax group names.
+
+    cmdre ~
+      Default: Undefined
+      If this is defined, then it is used instead of `name` for matching the
+      `cmdname` part. It is interpreted as a regular expression with "very
+      magic" mode activated (see |/\v|).
+
+    mathmode ~
+      Default: |v:false|
+      If true, then the command is a math mode command.
+
+    conceal ~
+      Default: |v:false|
+      If true, the `\cmdname` part and delimiters `{` and `}` are concealed.
+
+    concealchar ~
+      Default: Undefined
+      Specify a conceal character for the `\cmdname` part. With this, one can
+      easily create simple rules to display e.g. `\R` as `ℝ` (see config
+      example below).
+
+    opt ~
+      Default: |v:true|
+      If true, assumes `\cmdname` can be followed by an `[optional]` group.
+
+    optconceal ~
+      Default: Same as `conceal` key
+      If true, the option group `[optional]` is concealed.
+
+    arg ~
+      Default: |v:true|
+      If true, assumes `\cmdname` can be followed by an `{argument}` group.
+
+    argstyle ~
+      Default: Undefined.
+      Can be set to apply styling to the command argument by linking the
+      argument syntax group to one of the `texStyle` highlight groups (see
+      Table 5 in |vimtex-syntax-reference|). The following options are
+      available:
+        * `bold`
+        * `ital`
+        * `under`
+        * `boldital`
+        * `boldunder`
+        * `italunder`
+        * `bolditalunder`
+
+      Note: Fine grained control is of course also possible. Each defined
+            command gets one or more match groups, e.g. if you create a custom
+            command named `foo`, then it will usually have these groups:
+            `texCmdCFoo`, `texCFooOpt`, `texCFooArg`. One may then customize
+            the highlights as explained in |vimtex-syntax-core|.
+
+    argspell ~
+      Default: |v:true|
+      Specify this as |v:false| or 0 to disable spell checking of the command
+      argument.
+
+    arggreedy ~
+      Default: |v:false|
+      If |v:true| or 1, the syntax rule will "eat" as many arguments as
+      possible: `\cmdname[opt]{arg1}{arg2}...{argn}`
+
+    nextgroup ~
+      Default: Undefined
+      This is a string that, if defined and not empty, specifies
+      a comma-separated list of possible next syntax groups.
+
+    hlgroup ~
+      Default: Undefined
+      A string that can be used to indicate the target highlight group of the
+      command (`\cmdname`).
+
+  A couple of examples may be helpful: The first in the following list shows
+  how to use bolded style on a custom vector macro such as `\vct{v}`. The
+  second example shows how to conceal `\R` with `ℝ`. The third example shows
+  how one may use the `nextgroup` key, and the fourth shows how to define
+  a command whose argument should not be spell checked. >vim
+

+          \]
+<
+  Default value: []
+
+*g:vimtex_syntax_custom_cmds_with_concealed_delims*
+  This option works exactly as |g:vimtex_syntax_custom_cmds|, except it is
+  used specifically to add conceals with custom replacement characters for
+  single- and double-argument commands, e.g. >
+
+    \cmd1{argument}
+    \cmd2 {argument1} {argument2}
+<
+  Each element in the list must be a dictionary with the following keys. Most
+  of these keys are documented here: |g:vimtex_syntax_custom_cmds|. Only
+  the unique keys are described in full here.
+
+    name ~
+      Default: Undefined (REQUIRED)
+
+    nargs ~
+      Default: 1
+      Specify whether the command has 1 or 2 arguments.
+
+    cchar_open ~
+      Default: Undefined
+      Specify single letter replacement for the head (`\cmdname{`). If left
+      undefined, the head is fully concealed.
+
+    cchar_mid ~
+      Default: Undefined
+      Note: Only relevant if `nargs` = 2
+      Specify single letter replacement for the mid (`}{`). If left
+      undefined, the mid is fully concealed.
+
+    cchar_close ~
+      Default: Undefined
+      Specify single letter replacement for the tail (`}`). If left
+      undefined, the tail is fully concealed.
+
+    cmdre ~
+      Default: Undefined
+
+    mathmode ~
+      Default: |v:false|
+
+    argstyle ~
+      Default: Undefined.
+
+    argspell ~
+      Default: |v:true|
+
+    hlgroup ~
+      Default: Undefined
+
+  An example may be elucidating. Given the following configuration: >vim
+
+    let g:vimtex_syntax_custom_cmds_with_concealed_delims = [
+          \ {'name': 'ket',
+          \  'mathmode': 1,
+          \  'cchar_open': '|',
+          \  'cchar_close': '>'},
+          \ {'name': 'binom',
+          \  'nargs': 2,
+          \  'mathmode': 1,
+          \  'cchar_open': '(',
+          \  'cchar_mid': '|',
+          \  'cchar_close': ')'},
+          \]
+<
+  We should now see the following effect in a document: >latex
+
+    $\ket{x}$ and $\binom{n}{k}$
+
+    % will now look like this:
+
+    |x> and (n|k)
+<
+  Default value: []
+
+*g:vimtex_syntax_custom_envs*
+  A list of environments for which to apply custom styling. This allows to
+  define custom math environments or to specify custom environments for which
+  to load nested syntaxes. The latter is relevant e.g. if you use the
+  `\lstnewenvironment` from the `listings` package.
+
+  Each environment is expected to look like this: >latex
+
+    \begin{env_name}[optional argument]
+      …
+    \end{env_name}
+<
+  It is important to be aware that these customizations will be applied on top
+  of the existing syntax rules. They may therefore override both the core
+  syntax rules and extensions from syntax packages.
+
+  Each element in the list must be a dictionary with the following keys:
+
+    name ~
+      Default: Undefined (REQUIRED)
+      The name of the environment to highlight (`env_name`). The string is
+      used as a regular expression.
+
+    region ~
+      Default: `tex{Name}Zone`
+      The syntax group used to match the defined region.
+
+      Note: If `math` is |v:true|, then the region will always be set to
+      `texMathZoneEnv`.
+
+    math ~
+      Default: |v:false|
+      If true, then the environment is a math region.
+
+    starred ~
+      Default: |v:false|
+      Whether the corresponding starred environment should also be matched.
+
+    transparent ~
+      Default: |v:false|
+      If the matched syntax region should be transparent: |syn-transparent|.
+
+    opts ~
+      Default: Undefined
+      A string with additional options that will be passed to the `syntax
+      region` command (see |syn-region|).
+
+    contains ~
+      Default: Undefined
+      A comma-separated string of syntax groups that should be contained in
+      within the matched region (see |syn-contains|).
+
+    nested ~
+      Default: Undefined
+      This can be either a string or a dictionary:
+
+        |String|:     specify nested syntax to load inside the environment
+        |Dictionary|: specify "predicated" nested syntaxes (more flexible)
+
+      The dictionary uses the target syntax as the key and the "predicate" as
+      the value. This predicate is a string that must be contained within the
+      optional argument. See below for an example.
+
+      Notice that one should also be aware of |g:vimtex_syntax_nested|.
+
+  The following example creates three rules. The first creates the environment
+  `MyMathEnv` that opens a new math environment. The second creates
+  a `python_code` environment that applies nested Python syntax rules in the
+  environment region. The third rule creates a `code` environment that will
+  open nested syntax regions if the optional group contains the specified
+  predicate strings. >vim

+
+*g:vimtex_syntax_match_unicode*
+  Whether to highlight unicode characters. If enabled, it will match unicode
+  greek letters as `texCmdGreek` and a lot of other unicode symbols as
+  `texMathSymbol`.
+
+  Default value: |v:true|
+
+*g:vimtex_syntax_nested*
+  A dictionary for configuring nested syntaxes. The following keys are
+  available for configuration:
+
+    aliases ~
+      Holds a dictionary of aliases, such as mapping `C` to `c`. This is
+      useful e.g. because the Vim syntax files are case sensitive.
+
+    ignored ~
+      Holds a dictionary of ignore lists for each language. This is useful to
+      ignore some groups that may conflict in e.g. the `\begin{...}` or
+      `\end{...}` part of the nested syntax regions.
+
+  Default value: >vim
+
+    let g:vimtex_syntax_nested = {

+          \}
+
+*g:vimtex_syntax_nospell_comments*
+  Set to 1 to disable spell checking in comments.
+
+  Default value: 0
+
+*g:vimtex_syntax_packages*
+  A dictionary for package specific syntax configuration. Each key represent
+  a single package and the values are themselves configuration dictionaries.
+  All packages share the following options:
+
+    `load`  Specify when to load the package syntax addon.
+      0 = disable this syntax package
+      1 = enable this syntax package if it is detected (DEFAULT)
+      2 = always enable this syntax package
+
+  The following is a list of packages with additional options or packages that
+  deviate from the above specified defaults. Notice that conceal options
+  are affected by |g:vimtex_syntax_conceal_disable|.
+
+    amsmath ~
+      `load`     is 2 by default
+      `conceal`  whether to enable conceal; enabled by default
+
+    babel ~
+      `conceal`  whether to enable conceal; enabled by default
+
+    fontawesome5 ~
+      `conceal`  whether to enable conceal; enabled by default. Notice that
+                 the only point of this package is to apply conceals to
+                 fontawesome commands. Thus, disabling conceal here is
+                 equivalent to disabling the package.
+
+    hyperref ~
+      `conceal`  whether to enable conceal; enabled by default
+
+  Default: >vim
+
+    let g:vimtex_syntax_packages = {
+          \ 'amsmath': {'conceal': 1, 'load': 2},
+          \ 'babel': {'conceal': 1},
+          \ 'hyperref': {'conceal': 1},
+          \ 'fontawesome5': {'conceal': 1},
+          \}
+
+*g:vimtex_texcount_custom_arg*
+  Option that makes it possible to add custom arguments to `texcount` for
+  |:VimtexCountWords| and |:VimtexCountLetters|.
+
+  Default value: `''`
+
+*g:vimtex_text_obj_enabled*
+  Use this option to disable the text object mappings.
+
+  Default value: 1
+
+*g:vimtex_text_obj_linewise_operators*
+  List of operators that will act linewise on the delimiter text objects (i.e.
+  `ie/ae`, `i$/a$`, and `id/ad`). Note, for inline regions the operators will not
+  act linewise, since that would lead to side effects.
+
+  Default value: `['d', 'y']`
+
+*g:vimtex_text_obj_variant*
+  Select text object variants for command and environment text objects. The
+  choice is either VimTeX or |targets.vim|. Possible configuration options
+  are:
+
+  1. `'auto'`     (select `'targets'` if |targets.vim| is installed)
+  2. `'vimtex'`
+  3. `'targets'`
+
+  When using `'targets'`, the following additional text object kinds are
+  available:
+
+  - Prefix `I` and `A` instead of `i` and `a` for excluding inner whitespace or
+    including outer whitespace, respectively.
+  - Modifier `n` and `l` for next or previous (mnemonic: last).
+
+  For more details, see `doc/targets-textobj-cheatsheet.md`.
+
+  Default value: `'auto'`
+
+*g:vimtex_toggle_fractions*
+  Specify rules for toggling fractions with |<plug>(vimtex-cmd-toggle-frac)|,
+  which is mapped to `tsf` by default.
+
+  Default value: >vim
+
+    let g:vimtex_toggle_fractions = {
+          \ 'INLINE': 'frac',
+          \ 'frac': 'INLINE',
+          \ 'dfrac': 'INLINE',
+          \}
+
+*g:vimtex_toc_enabled*
+  Use this option to disable/enable table of contents (ToC).
+
+  Default value: 1
+
+*g:vimtex_toc_config*
+  This is a dictionary that can be used to configure the ToC. Each key
+  specifies a configuration option that can be changed. For configuration of
+  specific matchers, see |g:vimtex_toc_config_matchers|.
+
+  In the following, the possible configuration keys are explained briefly and
+  the default values are indicated.
+
+    `name` : `Table of contents (VimTeX)`
+      The name of the ToC buffer.
+
+    `mode` : 1
+      The ToC display mode, one of:
+      1: Separate window.
+      2: Separate window and location list.
+      3: Location list (and don't open it).
+      4: Location list (and open it).
+
+    `fold_enable` : 0
+      Whether to enable folding in the ToC window.
+
+    `fold_level_start` : -1
+      The starting fold level. The value -1 indicates that the start level is
+      the same as the `tocdepth` value.
+
+    `hide_line_numbers` : 1
+      If enabled, then line numbers will be hidden in the ToC window by
+      setting |nonumber| and |norelativenumber| locally.
+
+    `hotkeys_enabled` : 0
+      Set to 1 to enable individual hotkeys for ToC entries.
+
+    `hotkeys` : `abcdegijklmnopuvxyz`
+      A string of keys that are used to create individual hotkeys.
+
+    `hotkeys_leader` : `;`
+      The hotkey leader. Set to empty string to disable the leader.
+
+    `indent_levels` : 0
+      Set to 1 to indent the section levels in the ToC window.
+
+    `layers` : Undefined
+    `layer_status` : Dictionary >
+        { 'content': 1,
+          'label': 1,
+          'todo': 1,
+          'include': 1 }
+<      The initial state of the layers (1 for active, 0 for inactive). The
+      `layers` key may be used as a shorthand: it accepts a list of layers
+      that should be active.
+
+    `layer_keys` : Dictionary >
+        { 'content': 'C',
+          'label': 'L',
+          'todo': 'T',
+          'include': 'I'}
+<      Specify hotkeys for enabling/disabling the different layers.
+
+    `resize` : 0
+      Whether or not to automatically resize vim when index windows are
+      opened.
+
+      Note: This option makes sense if the index window is vertically split.
+
+    `refresh_always` : 1
+      Set to 0 to manually refresh ToC entries. This may be useful for very
+      large projects where generating the ToC entries becomes slow.
+
+      It may be useful to combine manually refreshing with a |BufWritePost|
+      autocommand, e.g.: >vim
+
+        augroup VimTeX
+          autocmd!
+          autocmd BufWritePost *.tex call vimtex#toc#refresh()
+        augroup END
+<
+      Or, if preferred, one may use a mapping such as: >vim
+
+        nnoremap <silent> <localleader>lf :call vimtex#toc#refresh()
+<
+    `show_help` : 1
+      Whether to display help text on top when the ToC is opened. If this is
+      disabled, we only show "Press h to toggle help text.".
+
+    `show_numbers` : 1
+      Set whether or not to show section numbers in ToC.
+
+    `split_pos` : `vert leftabove`
+      Define where index windows should be opened. This is a string that
+      contains either the word "full" to open in the current window, or
+      a position command. Use |:vert| if a vertical split is desired, and one
+      of |:leftabove|, |:rightbelow|, |:topleft|, and |:botright| to specify
+      the desired split position.
+
+    `split_width` : 30
+      For vertically split windows: Set width of index window.
+
+    `tocdepth` : 3
+      Define the depth of section levels to display. This attempts to mimic
+      the corresponding latex variable `tocdepth`. For more info, see:
+      https://en.wikibooks.org/w/index.php?title=LaTeX/Document_Structure
+
+      Note: This will also change the width of the number column according to
+            the space needed to show the section numbers.
+
+    `todo_sorted` : 1
+      Whether or not to sort the TODOs at the top of the ToC window.
+
+*g:vimtex_toc_config_matchers*
+  This is a dictionary that can be used to configure the built-in ToC
+  matchers. See below for a specification of the ToC matcher "objects" and the
+  various keys that can be defined/changed (|toc_matcher_specification|).
+
+  To configure/alter a built-in matcher, one can do this: >vim
+
+    let g:vimtex_toc_config_matchers = {
+          \ 'MATCHER1': {OPTIONS},
+          \ 'MATCHER2': {OPTIONS},
+          \}
+<
+  The available options are described in |toc_matcher_specification|. Please
+  note that the built-in matchers should generally just work well for most
+  people. However, this option allows at least two useful things: to disable
+  a built-in matcher and to change the priority of a built-in matcher. The
+  following is a full example that shows how this could be used: >vim
+
+    let g:vimtex_toc_config_matchers = {
+          \ 'beamer_frame': {'disable': 1},
+          \ 'todo_fixme': {'priority': -1},
+          \ 'index': {'title': 'MyFancy Index Title'},
+          \}
+<
+  Note: The available built-in matchers are defined in separate files under
+        `/autoload/vimtex/parser/toc/*.vim`.
+
+  Default value: {}
+
+                                                    *toc_matcher_specification*
+  A ToC matcher is defined as a |Dictionary| where the possible keys are
+  specified below. In order to write a matcher, one should also be aware of
+  the `context` argument that is passed to the matcher functions, as well as
+  the specification of the `toc entry` return value. However, since this kind
+  of customization is advanced I refer users to the source file for further
+  specification of these objects. In particular, see the function
+  `s:toc.parse(...)` in `/autoload/vimtex/toc.vim`.
+
+    re ~
+      Type: |String|
+      Required: `yes`
+      This specifies a regular expression that should match the current line
+      for the desired ToC entry.
+
+    prefilter_re ~
+      Type: |String|
+      Required: `maybe` (this or `prefilter_cmds` should be specified)
+      This specifies a regular expression that must match the current line for
+      the desired ToC entry. This is used as a prefilter to make things
+      faster, and it does not need to be a perfect match. The `re` key may
+      often be a complex and therefore slow regular expression. This key
+      should represent a simple and fast regular expression that may match
+      more than the desired entry.
+
+    prefilter_cmds ~
+      Type: List of |String|
+      Required: `maybe` (this or `prefilter_re` should be specified)
+      This is similar to `prefilter_re`, except it specifies a list of command
+      names (regular expressions). For instance, it should contain `todo` for
+      a ToC matcher for `\todo` commands.
+
+    priority ~
+      Type: |expr-number| (default: 0)
+      Required: `no`
+      Priority is used for sorting the ToC matchers. High priority matchers
+      will be tried first, and only one matcher will match a given line. Note
+      that the built-in matchers have priority values between 0 and 2.
+
+    in_preamble ~
+      Type: 0 or 1 (default: 0)
+      Required: `no`
+      If the entry may appear in the preamble.
+
+    in_content ~
+      Type: 0 or 1 (default: 1)
+      Required: `no`
+      If the entry may appear in the main content.
+
+    title ~
+      Type: |String|
+      Required: `no`
+      If the matcher does not have a `get_entry` key, then it will use
+      a simple, general matcher function to generate the entry. In this case,
+      the `title` key should be specified to give the title of the ToC entry.
+
+    get_entry ~
+      Type: |Dictionary-function|
+      Arguments: `context`
+      Returns: `toc entry`
+      Required: `no`
+      This is the general way to define ToC entries. It allows to define the
+      ToC entry based on the context. See `/autoload/vimtex/parser/toc.vim`
+      for examples on how to use this.
+
+    continue ~
+      Type: |Dictionary-function|
+      Arguments: `context`
+      Returns: `toc entry`
+      Required: `no`
+      Some entries may be specified over several lines, in which case this key
+      becomes necessary in combination with the `get_entry` key. See the built
+      in `s:matcher_section` matcher for an example on how to use this.
+
+    name ~
+      Type: |String|
+      Required: `no`
+      Mostly for making it easier to debug a specific matcher. Without a name,
+      the matcher will be registered with a semi random numbered name like
+      `custom1`.
+
+    disable ~
+      Type: |Boolean| (default: |v:false|)
+      Required: `no`
+      If true, then the matcher will be disabled.
+
+*g:vimtex_toc_custom_matchers*
+  This option is a list of custom ToC matchers, see |toc_matcher_specification|.
+
+  As an example, one can use this option to add ToC entries for a custom
+  environment. Say you have defined an environment `mycustomenv`, then
+  instances of this environment could be added to the ToC with the following
+  configuration: >vim
+
+    let g:vimtex_toc_custom_matchers = [
+            \ { 'title' : 'My Custom Environment',
+            \   're' : '\v^\s*\\begin\{mycustomenv\}' }
+            \]
+<
+  Default value: []
+
+*g:vimtex_toc_todo_labels*
+  Dictionary of keywords that should be recognized in comments for the todo
+  layer. The values represent the labels used in the ToC.
+
+  Default value: `{'TODO': 'TODO: ', 'FIXME': 'FIXME: '}`
+
+*g:vimtex_toc_show_preamble*
+  Whether to include the preamble in the ToC.
+
+  Default value: 1
+
+*g:vimtex_ui_method*
+  A dictionary that specifies the backend for various input methods. The
+  method names are the keys of the dictionary and the backend choices are the
+  values.
+
+  The available methods:
+
+    confirm:  Confirm dialogues (e.g. before opening documentation)
+    input:    Input dialogues (e.g. for |<plug>(vimtex-cmd-change)|)
+    select:   Selection dialogues (e.g. to select when there are multiple
+              choices for documentation)
+
+  The available backends:
+
+    nvim:     Popup menu created with neovim APIs.
+    vim:      Currently there is no Vim-specific implementation. Setting the
+              backend to "vim" will currently fallback to "legacy".
+    legacy:   Legacy backends that are created by |:echo|ing the menus and
+              using |input()| and similar for getting input.
+
+  Default: >vim
+
+    " On neovim
+    let g:vimtex_ui_method = {
+          \ 'confirm': 'nvim',
+          \ 'input': 'nvim',
+          \ 'select': 'nvim',
+          \}
+
+    " Otherwise
+    let g:vimtex_ui_method = {
+          \ 'confirm': 'legacy',
+          \ 'input': 'legacy',
+          \ 'select': 'legacy',
+          \}
+
+*g:vimtex_view_enabled*
+  Use this option to disable/enable the VimTeX viewer interface.
+
+  Default value: 1
+
+*g:vimtex_view_automatic*
+  If enabled, the viewer should open automatically when compilation has
+  started in `continuous` mode and if `callback` is enabled, or if
+  `continuous` mode is disabled. This should work for the following compilers:
+  * |vimtex-compiler-latexmk|
+  * |vimtex-compiler-latexrun|
+  * |vimtex-compiler-arara|
+  * |vimtex-compiler-tectonic|
+
+  Default value: 1
+
+*g:vimtex_view_use_temp_files*
+  When enabled, this option specifies to copy the `.pdf` and `.synctex.gz`
+  files after successful compilation. The viewer will use the copies, which
+  helps to avoid issues such that as the pdf becoming unavailable during
+  compilation.
+
+  The copies are named similar to the original files with a `_` prefix.
+
+  Note: This option is only relevant for the `latexmk` compiler backend.
+        `latexrun` already ensures that the output file is updated only after
+        the compilation is completed.
+
+  Default value: |v:false|
+
+*g:vimtex_view_forward_search_on_start*
+  If disabled, the first invocation of the viewer will not perform a forward
+  search to the current cursor position.
+
+  Note: This option is only relevant when |g:vimtex_view_method| is set to
+        either `mupdf`, `zathura`. See also the specific viewer sections for
+        more info: |vimtex-view-mupdf|, |vimtex-view-zathura|.
+
+  Default value: 1
+
+*g:vimtex_view_reverse_search_edit_cmd*
+  When working in a multi-file project, initiating inverse search (see
+  |vimtex-synctex-inverse-search|) may require opening a file that is not
+  currently open in a window. This option controls the command that is used to
+  open files as a result of an inverse search.
+
+  Examples:
+    * `edit`     open buffer in current window
+    * `tabedit`  open buffer in new tab page
+    * `split`    split current window to open buffer
+
+  Default value: `edit`
+
+*g:vimtex_view_method*
+  Set the viewer method. By default, a generic viewer is used through the
+  general view method (e.g. `xdg-open` on Linux).
+
+  Possible values:
+    * `'general'`
+    * `'mupdf'`             |vimtex-view-mupdf|
+    * `'skim'`              |vimtex-view-skim|
+    * `'zathura'`           |vimtex-view-zathura|
+    * `'zathura_simple'`    |vimtex-view-zathura-simple|
+
+  See |vimtex-view-configuration| for more information on various popular
+  viewers and on how to configure them.
+
+  Default: `general`
+
+*g:vimtex_view_general_options*
+  Set options for the specified general viewer, see |vimtex-view-general|.
+  The options are parsed to substitute the following keywords:
+
+    `@pdf`    Path to pdf file
+    `@tex`    Path to tex file
+    `@line`   Current line number
+    `@col`    Current column number
+
+  Default value: `'@pdf'`
+
+*g:vimtex_view_mupdf_options*
+*g:vimtex_view_zathura_options*
+  Set options for mupdf and Zathura, respectively. See also:
+    * |vimtex-view-mupdf|
+    * |vimtex-view-zathura|
+    * |vimtex-view-zathura-simple|
+
+  Default value: `''`
+
+*g:vimtex_view_general_viewer*
+  Use generic viewer application, see |vimtex-view-general|.
+
+  Default value:
+    Linux:   `xdg-open`
+    macOS:   `open`
+    Windows: `SumatraPDF` or `mupdf` if available, else `start ""`
+
+*g:vimtex_view_mupdf_send_keys*
+  A string of keys that will be sent to MuPDF just after the PDF file has been
+  opened.
+
+  Default value: `''`
+
+*g:vimtex_view_sioyek_exe*
+  The name or path of the Sioyek executable. The default should usually work,
+  but in some cases it can be useful or necessary to specify the executable
+  directly. E.g., if one downloads a release version, it may be named
+  something like `'Sioyek-x86_64.AppImage'`. Unless the executable location is
+  available in `PATH` one must use an absolute path here.
+
+  Default value: `'sioyek'`
+
+*g:vimtex_view_sioyek_options*
+  Set additional command-line options for Sioyek (|vimtex-view-sioyek|). This
+  can e.g. be used to add the `--reuse-instance` or `--reuse-window` option,
+  which some users prefer.
+
+  Default value: `''`
+
+*g:vimtex_view_skim_activate*
+  Set this option to 1 to make Skim have focus after command |:VimtexView| in
+  addition to being moved to the foreground.
+
+  Default value: 0
+
+*g:vimtex_view_skim_sync*
+  Set this option to 1 to make Skim perform a forward search after successful
+  compilation.
+
+  Default value: 0
+
+*g:vimtex_view_skim_reading_bar*
+  Set this option to 1 to highlight current line in PDF after command
+  |:VimtexView| or compiler callback.
+
+  Default value: 0
+
+*g:vimtex_view_skim_no_select*
+  Set this option to 1 to prevent Skim from selecting the text after command
+  |:VimtexView| or compiler callback.
+
+  Default value: 0
+
+*g:vimtex_view_texshop_activate*
+  Set this option to 1 to make TeXShop have focus after command |:VimtexView| in
+  addition to being moved to the foreground.
+
+  Default value: 0
+
+*g:vimtex_view_texshop_sync*
+  Set this option to 1 to make TeXShop perform a forward search after successful
+  compilation.
+
+  Default value: 0
+
+*g:vimtex_view_zathura_check_libsynctex*
+  Check on startup if Zathura is compiled with libsynctex. This is done by
+  default because Zathura on some systems is compiled without libsynctex
+  support, in which case forward and inverse search will not work. When this
+  is the case, the startup check will provide a notification to the user.
+
+  If this option is set to 0 or |v:false|, then the check is skipped.
+
+  Default value: 1
+
+*g:vimtex_callback_progpath*
+  The path to the Vim/neovim executable. This is currently passed to Zathura
+  and Sioyek for use with synctex callbacks; see |vimtex-view-zathura| and
+  |vimtex-view-sioyek|.
+
+  You usually don't have to touch this variable; VimTeX will |v:progpath| if
+  the option is not defined. But some people may use wrappers and similar to
+  load Vim/neovim, in which case one may want to specify the executable
+  directly.
+
+  Default value: Undefined
+
+*$VIMTEX_OUTPUT_DIRECTORY*
+  This environment variable allows to specify the output directory of
+  generated LaTeX files. If it exists and is a valid path, this path will be
+  used as the output directory. This has two main use cases:
+
+  1. It allows to use a custom output directory for different projects.
+  2. It allows to specify an output directory for projects where one uses
+     compiler backends such as |vimtex-compiler-arara|. This makes it possible
+     to make e.g. the |vimtex-view| feature to work as expected if output
+     directories are used with arara.
+
+  Note: This will override `out_dir` (and `aux_dir`) of options like
+        |g:vimtex_compiler_latexmk| and |g:vimtex_compiler_latexrun|.

+                          package to show docs for. If no argument is
+                          supplied, it parses the command under the cursor and
+                          opens the most relevant documentation.

+:VimtexLog                Open a scratch buffer to show message log with

+                                             *<plug>(vimtex-compile)*
+:VimtexCompile [opts]     If the compiler supports and is set to run in
+                          continuous mode, then this command works as
+                          a compiler toggle. If not, this command will run
+                          a single shot compilation.
+
+                          Arguments to the command will be passed on as options
+                          when starting the compiler. This allows the user to
+                          start the compiler with different options without
+                          changing any configuration. That is, if the user uses
+                          the latexmk backend, then adding any option argument
+                          is equivalent to adding them to the `'options'` key
+                          of |g:vimtex_compiler_latexmk|.
+
+                          Note: Special items in the arguments will be
+                          expanded as explained in |expandcmd|.

+:VimtexCompileSelected    Compile the selected part of the current LaTeX file.
+                          When used as a command, it takes a range, e.g.: >
+
+                            :start,end VimtexCompileSelected
+
+<                          When used as a normal mode mapping, the mapping
+                          will act as an |operator| on the following motion or
+                          text object. Finally, when used as a visual mode
+                          mapping, it will act on the selected lines.
+
+                          Note: This always works linewise!
+
+                          The command compiles the selected text by copying it
+                          to a temporary file with the same preamble as the
+                          current file. It will be compiled similarly to
+                          a single shot compile (see |:VimtexCompileSS|. If
+                          there are errors, they will be shown in the quickfix
+                          list.
+
+                          One may specify a custom template with a template
+                          file in which any (single!) line with the exact
+                          content `%%% VIMTEX PLACEHOLDER` will be
+                          interchanged with the selected lines. This allows to
+                          customize the preamble and surrounding content. The
+                          template file should be named `vimtex-template.tex`
+                          or `<head>-vimtex-template.tex`, where `<head>`
+                          implies the head of the current file name with the
+                          extension removed. E.g., for a file `foo.tex`, one
+                          may specify a custom template
+                          `foo-vimtex-template.tex`. This will have a higher
+                          priority than `vimtex-template.tex`.

+
+                          Note: One may access the information through the

+                                `opts` is a dictionary with the following
+                                keys (defaults indicated): >
+
+                                'range' : [1, line('$')]

+                                total count. This makes it possible to use for
+                                e.g. statusline functions. If the `opts` dict
+                                is not passed, then the defaults are assumed.

+:VimtexToggleMain         In general, VimTeX detects the main file for the
+                          current LaTeX project and uses it for compilation
+                          and many other features. However, in some cases it
+                          may be useful to instead focus on the current file,
+                          for instance in large projects. In such cases, one
+                          can use |:VimtexToggleMain| to change which file to
+                          use as the "current project". It is easy to toggle
+                          back and forth, and both the "main project" and the
+                          "local project" can be used simultaneously if
+                          desired (e.g. for compilation).
+
+                          Note: To compile the current file when it is part of
+                                a larger project, one must of course include
+                                a preamble and the `\begin/\end{document}`! It is
+                                possible to have a working preamble in every
+                                file in a multi-file project with `subfiles`,
+                                see |vimtex-subfiles|. See also
+                                |g:vimtex_subfile_start_local|.

+                          files are located at |g:vimtex_cache_root| and can
+                          also be deleted manually.

+  the folds are refreshed appropriately.
+
+*<plug>(vimtex-env-delete)*
+*<plug>(vimtex-env-delete-math)*
+*<plug>(vimtex-env-change)*
+*<plug>(vimtex-env-change-math)*
+  Delete/Change surrounding environment. When changing, there will be
+  sensible completion candidates, see |cmdline-completion|. See also

+
+*<plug>(vimtex-cmd-delete)*

+  Delete/Change surrounding command. See also |g:vimtex_echo_verbose_input|.
+
+*<plug>(vimtex-delim-delete)*
+*<plug>(vimtex-delim-change-math)*
+  Delete/Change surrounding (math) delimiter. See also
+  |g:vimtex_echo_verbose_input|.
+
+*<plug>(vimtex-cmd-toggle-frac)*
+  Toggle fractions between inline mode (`num/den`) and command mode
+  (`\frac{num}{den}`). Fractions are toggled according to the map specified by
+  |g:vimtex_toggle_fractions|.
+
+  In visual mode, the selected text is toggled if it matches either
+  a `\frac{}{}` command or a `numerator / denominator` string. In normal mode,
+  we try to detect the surrounding fraction command or inline fraction
+  expression. If successful, the detected fraction is toggled.
+
+*<plug>(vimtex-cmd-toggle-star)*
+*<plug>(vimtex-env-toggle-star)*
+  Toggle starred command/environment.
+
+*<plug>(vimtex-env-toggle-math)*
+  Toggle between inline math and displayed math, e.g.: >
+
+                      ts$        \[
+    $f(x) = 1$         ↔            f(x) = 1
+                                 \]
+<
+  One may change the toggle sequence with |g:vimtex_env_toggle_math_map|.
+
+*<plug>(vimtex-cmd-toggle-break)*
+  Toggle the line-break macro `\\` at the end of current line. This may
+  be convenient when working with array and math environments.
+
+*<plug>(vimtex-env-surround-line)*
+*<plug>(vimtex-env-surround-operator)*
+*<plug>(vimtex-env-surround-visual)*
+  Surround the current line, operated text, or visually selected text, with an
+  environment specified during execution. More specifically, this adds
+  `\begin{ENV}` on the line above and `\end{ENV}` on the line below the
+  specified region. The resulting region is filtered to apply proper
+  indentation (see |==|).
+
+  Note: This only works linewise!
+  Note: There is no default for the operator version.
+
+*<plug>(vimtex-delim-toggle-modifier)*
+*<plug>(vimtex-delim-toggle-modifier-reverse)*
+  Toggle delimiter modifiers, by default alternating between `(...)` and
+  `\left(...\right)`.  The normal mode mapping toggles the closest surrounding
+  delimiter, whereas the visual mode mapping toggles all delimiters that are
+  fully contained in the visual selection.  The visual selection is preserved.
+
+  When |g:vimtex_delim_toggle_mod_list| is set to contain more than one set of
+  modifiers, these mappings iterate through the list instead of just toggling.
+  For example, one may alternate between `(...)`, `\bigl(...\bigr)`,
+  `\Bigl(...\Bigr)`, and so on.  These mappings accept a [count], which allows
+  the modifier to be incremented multiple steps at a time.  The `-reverse`
+  mapping goes backwards through the modifier list instead of forwards.

+  See also |g:vimtex_delim_toggle_mod_list| and |g:vimtex_delim_list|.
+
+*<plug>(vimtex-cmd-create)*
+  This mapping works in both insert mode, normal mode and visual mode. It is
+  mapped by default to <f7>. See below for the behaviour in the different
+  modes.
+
+  Insert mode:
+    Convert the preceding text into a LaTeX command. That is, it prepends
+    a backslash and adds an opening brace. It also moves the cursor to the end
+    of the word. If you also want the closing brace (e.g. to emulate
+    delimitMate [0] or any of its like), you can add the following to your
+    `~/.vim/after/ftplugin/tex.vim`: >vim
+
+      imap <buffer> <f7> <plug>(vimtex-cmd-create)}<left>
+<
+    [0]: https://github.com/Raimondi/delimitMate
+
+  Normal/Visual mode:
+    Surrounds the word under the cursor/visual selection by the command
+    provided in an input prompt.
+
+*<plug>(vimtex-delim-close)*
+  Close the current environment or delimiter (insert mode), except the
+  top-level `document` environment.

+INSERT MODE MAPPINGS                                             *vimtex-imaps*
+
+Some LaTeX commands are very common, and so it is both natural and convenient
+to have insert mode mappings/abbreviations for them. VimTeX therefore
+provides a list of such mappings that are enabled by default, see
+|g:vimtex_imaps_list|. The mappings utilize a map leader defined by
+|g:vimtex_imaps_leader|. The default list of maps are all math mode mappings,
+but one may also add mappings that are available and useful outside of math
+mode. To see the list of mappings that are created, one can use the command
+|:VimtexImapsList|, which is by default mapped to `<localleader>lm`.
+
+It is of course possible to customize the list of mappings. First, one may
+specifically disable the entire imaps feature with |g:vimtex_imaps_enabled| or
+specific default mappings through |g:vimtex_imaps_disabled|. Second, one may
+specify |g:vimtex_imaps_list|, which will overwrite the default list. Finally,
+one may add new maps through calls to the function |vimtex#imaps#add_map|. The
+following are some examples of how to customize the mappings: >vim
+
+  " Disable \alpha and \beta mappings
+  let g:vimtex_imaps_disabled = ['a', 'b']
+
+  " Add custom mapping through vimtex#imaps#add_map
+  call vimtex#imaps#add_map({
+        \ 'lhs' : 'test',
+        \ 'rhs' : '\tested',
+        \ 'wrapper' : 'vimtex#imaps#wrap_trivial'
+        \})
+
+  " Add custom mapping: #rX -> \mathrm{X}
+  call vimtex#imaps#add_map({
+        \ 'lhs' : 'r',
+        \ 'rhs' : 'vimtex#imaps#style_math("mathrm")',
+        \ 'expr' : 1,
+        \ 'leader' : '#',
+        \ 'wrapper' : 'vimtex#imaps#wrap_math'
+        \})
+<
+                                                         *vimtex#imaps#add_map*
+
+This function is used to add new insert mode mappings. It takes a single
+dictionary argument: >vim
+
+  let add_map_arg = {
+    \ 'lhs' : lhs,
+    \ 'rhs' : rhs,
+    \ 'expr' : bool,
+    \ 'leader' : leader_key,
+    \ 'wrapper' : function_name,
+    \ 'context' : value,
+    \ }
+
+Explanation of the keys:
+
+  lhs ~
+    Mandatory argument. The left-hand side part of the map.
+
+  rhs ~
+    Mandatory argument. The right-hand side part of the map. There is one
+    utility function that can be useful:
+
+      *vimtex#imaps#style_math*
+        Wraps the RHS inside a specified command, e.g. `\myarg{RHS}`, if the
+        cursor is inside math mode.
+
+  expr ~
+    Either 0/|v:false| or 1/|v:true| (default: 0). If true, then the
+    right-hand side is evaluated before it is passed to the wrapper.
+    This is necessary e.g. for use with |vimtex#imaps#style_math|.
+
+  leader ~
+    Custom leader key. If the key is not present, then |g:vimtex_imaps_leader|
+    is used as leader key.
+
+  wrapper ~
+    The name of a wrapper function that is used to generate the `rhs`. Two
+    functions are available from VimTeX:
+
+      *vimtex#imaps#wrap_trivial*
+        Trivial wrapper: Simply returns `rhs`.
+
+      *vimtex#imaps#wrap_math*
+        Only define `rhs` if inside a math environment. This is the default
+        wrapper function and will be used if no other wrapper is supplied.
+
+      *vimtex#imaps#wrap_environment*
+        Only define `rhs` if inside a specified environment. The wrapper works
+        by utilizing the `context` key, which is a list that contains strings
+        and/or dictionaries:
+
+          i.  If the entry is a string, then the `lhs` is mapped to `rhs`
+              inside the specified environment.
+          ii. If the entry is a dictionary, then we assume it has two entries,
+              `envs` and `rhs`, where `envs` is a list of environment names.
+              If inside any environment in this list, then we expand to the
+              corresponding `rhs`. This allows one to create a mapping that
+              expands to different `rhs`s in different environments.
+
+    Of course, one may use custom wrapper functions. To write a custom wrapper
+    function, please see the source for examples on how the VimTeX wrappers
+    are written.
+
+  context ~
+    A value that can be used by the chosen wrapper function.
+
+                                                            *vimtex-neosnippet*
+                                                             *vimtex-UltiSnips*
+Note: that this feature is not the same as the snippet feature of |UltiSnips|
+or |neosnippet|. The imaps feature of VimTeX previously supported `automatic`
+snippets, but these have been removed after careful considerations and input
+from VimTeX users, please see VimTeX issue #295:
+https://github.com/lervag/vimtex/issues/295#issuecomment-164262446
+It has been decided that the best approach is to only provide basic mappings,
+and to let users manually create automatic snippets through the anonymous
+snippet functions in |UltiSnips| and |neosnippet|, please see |UltiSnips#Anon|
+and |neosnippet#anonymous|, respectively (these will work if the respective
+plugins are installed). Here are a couple of examples that show how to create
+such mappings: >vim
+
+  " Using neosnippet#anonymous
+  inoremap <silent><expr> __ neosnippet#anonymous('_${1}${0}')
+  inoremap <silent><expr> ^^ neosnippet#anonymous('^${1}${0}')
+
+  " Using UltiSnips#Anon
+  inoremap <silent> __ __<c-r>=UltiSnips#Anon('_{$1}$0', '__', '', 'i')<cr>
+  inoremap <silent> ^^ ^^<c-r>=UltiSnips#Anon('^{$1}$0', '^^', '', 'i')<cr>
+
+A drawback with the anonymous UltiSnips snippets is that they do not nest.
+That is, if you did `__` twice in a row, only the second one could be escaped.
+In recent versions of |UltiSnips|, one may set normal snippets to trigger
+automatically, see |UltiSnips-autotrigger|. This allows nesting, and is
+therefore a better approach than using the anonymous snippet function.
+

+EVENTS                                                          *vimtex-events*
+
+VimTeX defines some events using the |User| autocmd that may be used for
+further customization.
+
+  *VimtexEventQuit*
+    This event is triggered when the last buffer for a particular LaTeX project
+    is wiped (for example, using `:bwipeout`) and when Vim is quit.  The event
+    may be used, for instance, to cleanup up auxiliary build files or close
+    open viewers (see Examples below).  With Vim defaults, this event is not
+    triggered when using `:quit` or `:bdelete` since these commands merely hide
+    the buffer.  In multi-file projects, the event may be triggered multiple
+    times.  The `b:vimtex` variable contains context data for the quitting
+    file or project.  For example, `b:vimtex.tex` identifies the tex file being
+    wiped, or the main tex file of a multi-file project.
+
+    Note: Commands such as |:VimtexClean| does not always work as expected
+          with this event. This is because, when quitting vim, the current
+          buffer does not necessarily have filetype "tex".
+
+  *VimtexEventInitPre*
+*VimtexEventInitPost*
+    These events are triggered at the start/end of VimTeX initialization.  The
+    post event may e.g. be used to automatically start compiling a document.
+
+  *VimtexEventCompileStarted*
+    This event is triggered after compilation is started.
+
+  *VimtexEventCompileStopped*
+    This event is triggered after compilation is stopped.
+
+  *VimtexEventCompiling*
+    This event is triggered when the compiler backend triggers a new
+    compilation. This is only supported by |vimtex-compiler-latexmk|.
+
+  *VimtexEventCompileSuccess*
+*VimtexEventCompileFailed*
+    These events are triggered after successful/failed compilation and
+    allows users to add custom callback functionality.
+
+  *VimtexEventTocCreated*
+    This event is triggered after a ToC window is created.
+
+  *VimtexEventTocActivated*
+    This event is triggered when a ToC entry has been activated. This allows
+    to add custom behaviour after opening an entry, e.g. positioning the
+    buffer window with the |zt| or |zz| mappings.
+
+  *VimtexEventView*
+    This event is triggered after the viewer has opened/forward search has
+    been performed by the command |:VimtexView| or the related mapping.
+
+  *VimtexEventViewReverse*
+    This event is triggered at the end of the |vimtex#view#inverse_search|
+    function, which can be used as the callback function for reverse goto from
+    a PDF viewer.
+
+Examples (Vimscript) - see below for a Lua example: >vim
+
+  " Compile on initialization, cleanup on quit
+  augroup vimtex_event_1
+    au!
+    au User VimtexEventQuit     VimtexClean
+    au User VimtexEventInitPost VimtexCompile
+  augroup END
+
+  " Close viewers when VimTeX buffers are closed
+  function! CloseViewers()
+    if executable('xdotool')
+          \ && exists('b:vimtex.viewer.xwin_id')
+          \ && b:vimtex.viewer.xwin_id > 0
+      call system('xdotool windowclose '. b:vimtex.viewer.xwin_id)
+    endif
+  endfunction
+
+  augroup vimtex_event_2
+    au!
+    au User VimtexEventQuit call CloseViewers()
+  augroup END
+
+  " Add custom mappings in ToC buffer

+    au!
+    au User VimtexEventTocCreated call TocMappings()
+  augroup END
+
+  " Specify window position when opening ToC entries
+  augroup vimtex_event_4
+    au!
+    au User VimtexEventTocActivated normal! zt
+  augroup END
+
+  " Specify extra behaviour after reverse goto
+  augroup vimtex_event_4
+    au!
+    au User VimtexEventViewReverse normal! zMzvzz
+  augroup END
+
+Examples - Lua: >lua
+
+  local au_group = vim.api.nvim_create_augroup("vimtex_events", {}),
+
+  -- Cleanup on quit
+  vim.api.nvim_create_autocmd("User", {
+    pattern = "VimtexEventQuit",
+    group = au_group,
+    command = "VimtexClean"
+  })

+TEXT OBJECTS                                              *vimtex-text-objects*
+
+Text objects (and motions) are a fundamental feature in Vim. Operations can be
+combined with motions or text objects in endless ways and can be repeated with
+the dot operator (|repeat.txt|). If you are reading this and do not know about
+these things, then it is strongly advised to read the help section about
+|text-objects| and the famous Stack Overflow post "Your problem with Vim is
+that you don't grok vi":
+http://stackoverflow.com/questions/1218390/what-is-your-most-productive-shortcut-with-vim/1220118#1220118
+
+VimTeX defines LaTeX specific text objects (and motions). These are all
+mappings, and as such, they are also described in the sections
+|vimtex-mappings| and |vimtex-default-mappings|.
+
+The usual convention for text object mappings is to prepend "a" to select "a"n
+object, including the whitespace/delimiters/etc, and to prepend "i" to select
+the corresponding "inner" object. This is the case for VimTeX text objects,
+e.g. by default, `vie` will visually select the inner part of an environment,
+whereas `vae` will select the entire environment including the boundaries.
+
+VimTeX supports the well known |targets.vim| as a "backend" for the command
+and environment text objects (`ie`/`ae` and `ic`/`ac`). This should work
+automatically, see |g:vimtex_text_obj_variant| for more info.
+
+Some examples of how to use the text objects can be useful. The following is
+a simple table that shows the original text on the left, the keys that are
+typed in the middle, and the result on the right. The bar "|" indicates the
+cursor position before the operation. >
+
+  BEFORE                       KEYS    AFTER
+  \comm|and{arg}               dic     \command{}
+  \command{a|rg}               gUac    \COMMAND{ARG}
+
+  \lef|t( asd \right)          cid     \left(| \right)
+
+  \begin{x}                    die     \begin{x}
+    hello world|                       \end{x}
+  \end{x}
+
+  $math | here$                da$
+
+  \begin{itemize}                      \begin{itemize}
+    \item hello moon|          cim       \item |
+  \end{itemize}                        \end{itemize}
+
+  \begin{itemize}                      \begin{itemize}
+    \item hello moon|          dam     \end{itemize}
+  \end{itemize}
+
+Note: The "greediness" of the command text objects (`ic` and `ac`) can be
+      controlled with |g:vimtex_parser_cmd_separator_check|.
+
+Note: Some of the text objects rely on syntax highlighting (|vimtex-syntax|)
+      to work. That is, some text objects check the syntax groups to determine
+      the proper regions. Examples include the math text objects (e.g.
+      |<plug>(vimtex-a$)| and |<plug>(vimtex-i$)|).

+==============================================================================
+COMPLETION                                                  *vimtex-completion*
+
+If |g:vimtex_complete_enabled| is 1 (default), then VimTeX sets the
+'omnifunc' to provide omni completion, see |compl-omni|.  Omni completion is
+then accessible with |i_CTRL-X_CTRL-O|. If desired, one may set
+|g:vimtex_complete_close_braces|, which makes the completion include closing
+braces.
+
+The omni completion completes citations, labels, glossary entries and
+filenames. The following sections document the various kinds of completions
+provided by VimTeX's completion function.
+
+A lot of people expect VimTeX and Vim/neovim to provide `automatic`
+completion, aka `autocomplete`. However, autocompletion is not a built-in
+feature of Vim/neovim. The last section of this chapter presents some
+alternatives to plugins that provide an autocomplete engine and how to
+configure it with VimTeX, see |vimtex-complete-auto|.
+
+Associated settings:
+* |g:vimtex_complete_bib|
+* |g:vimtex_complete_close_braces|
+* |g:vimtex_complete_enabled|
+* |g:vimtex_complete_ignore_case|
+* |g:vimtex_complete_ref|
+* |g:vimtex_complete_smart_case|
+
+------------------------------------------------------------------------------
+COMPLETE CITATIONS                                      *vimtex-complete-cites*
+
+Citation completion is triggered by `'\cite{'` commands. The completion parses
+included bibliography files (`*.bib`) and `thebibliography` environments to
+gather the completion candidates.
+
+By default, cite completion is "smart" in that it allows to complete on author
+names, title, and similar by matching against a match string defined by
+|g:vimtex_complete_bib.match_str_fmt|. If one prefers, one may set the
+`simple` key of |g:vimtex_complete_bib| to only allow completion on the
+bibkeys directly. This should typically work better with autocomplete plugins.
+
+As an example of the smart completion, assume that a bibliography file is
+included with the following entry: >bibtex
+
+  @book{knuth1981,
+    author = "Donald E. Knuth",
+    title = "Seminumerical Algorithms",
+    publisher = "Addison-Wesley",
+    year = "1981"
+  }
+
+Then, with the default configuration, the bibliography key `knuth1981` will be
+completed with e.g.: >
+
+  \cite{Knuth 1981<CTRL-X><CTRL-O>
+  \cite{algo<CTRL-X><CTRL-O>
+  \cite{Don.*Knuth<CTRL-X><CTRL-O>
+
+As is shown in the last example, the search string (e.g. `Don.*Knuth`) is
+applied as a regular expression.
+
+------------------------------------------------------------------------------
+COMPLETE LABELS                                        *vimtex-complete-labels*
+
+Label completion is triggered by `\ref{` commands.  The completion parses every
+relevant aux file to gather the completion candidates.  This is important,
+because it means that the completion only works when the LaTeX document has
+been compiled.
+
+As an example: >
+
+  \ref{sec:<CTRL-X><CTRL-O>
+
+offers a list of all matching labels with a menu that contains the associated
+value and page number.
+
+The completion base is matched as a regex in the following order: >
+
+  \ref{<base><CTRL-X><CTRL-O>
+<
+1. The menu, which contains the reference value and page number.
+2. The actual labels.
+3. The menu and label, separated by whitespace. An example: >
+
+     \ref{eq 2<CTRL-X><CTRL-O>
+<
+   This matches "eq" in the label and "2" in the menu.
+
+Finally, it should also be mentioned that for `\eqref`, the candidates will
+automatically be filtered to only show equation references.
+
+------------------------------------------------------------------------------
+COMPLETE COMMANDS AND ENVIRONMENTS                   *vimtex-complete-commands*
+                                                 *vimtex-complete-environments*
+
+Command completion is available after `\` and should provide completion
+candidates for relevant LaTeX commands.  The document's preamble is analysed,
+and commands will be completed for the loaded packages as well as those
+defined within the preamble using `\newcommand`, `\let` and `\def`.  Environment
+completion is also available after `\begin{` or `\end{`.  As with commands, the
+suggested environment names come from the loaded packages and `\newenvironment`
+definitions in the preamble.
+
+A lot of packages are supported, see the path `/autoload/vimtex/complete` for
+a relevant file listing.
+
+------------------------------------------------------------------------------
+COMPLETE FILE NAMES                                 *vimtex-complete-filenames*
+
+File name completion is available for the following macros:
+
+  `\includegraphics{`
+    Completes image file names.
+
+  `\input{`
+  `\include{`
+  `\includeonly{`
+    Complete `.tex` files.
+
+  `\includepdf{`
+    Complete `.pdf` files. This macro is provided by the `pdfpages` package.
+
+  `\includestandalone{`

+available for `\documentclass` and `\PassOptionsToClass`, and bibliography
+style completion is available for `\bibliographystyle`.
+
+These completion types all rely on the contents of `ls-R` files that are found
+with: >
+
+  kpsewhich --all ls-R
+
+Packages and documentclasses installed at `TEXMFHOME` will also be searched.
+The default value can be found with: >

+AUTOCOMPLETE                                             *vimtex-complete-auto*
+
+Vim does not provide automatic completion by itself, but there exist at least
+several good plugins that provide this: |coc-nvim|, |deoplete|, |neocomplete|,
+|ncm2|, |nvim-completion-manager|, |youcompleteme|, and |nvim-compe|.
+Moreover, there is |VimCompletesMe| that overrides <tab> to trigger different
+built-in completions, such as the omni-completion by VimTeX, depending on the
+context. See below for descriptions on how to setup these with VimTeX.
+
+coc.nvim ~
+                                                     *vimtex-complete-coc.nvim*
+|coc-nvim| is an intellisense engine for Vim8 & Neovim. It's a completion
+framework and language server client which supports extension features of
+Visual Studio Code. The project is here: https://github.com/neoclide/coc.nvim.
+
+|coc-nvim| can be installed using vim-plug: >vim
+
+  Plug 'neoclide/coc.nvim'
+
+However, it does require some more steps, and users are recommended to read
+the installation instructions in the `coc.nvim` wiki:
+https://github.com/neoclide/coc.nvim/wiki/Install-coc.nvim
+
+To configure for VimTeX, one should use the extension plugin |coc-vimtex|,
+which may be found here: https://github.com/neoclide/coc-vimtex. To use it,
+first make sure you have |coc-nvim| installed, then just run: >vim
+
+  :CocInstall coc-vimtex
+
+The `coc-vimtex` extension has a few options that can be configured in the
+`coc-settings.json` file. See the documentation for |coc-nvim| to learn how to
+apply the configurations. The following is a list of the options with a short
+description as it is specified on the project web page: >
+
+  coc.source.vimtex.disableSyntaxes    disabled syntax names
+  coc.source.vimtex.enable             set to false to disable this source
+  coc.source.vimtex.priority           priority of source, default 99
+  coc.source.vimtex.shortcut           shortcut used in menu of completion item
+
+Note: The README of `coc.nvim` suggests using `noremap K` to show
+documentation. `K` is also used by VimTeX as one of the default maps (see
+|vimtex-default-mappings|) for the same purpose. To enable VimTeX's mapping
+for `.tex` files (since `coc.nvim` does not have a doc source), do one of the
+following:
+
+* Manually remap for `.tex` files: Put the following in your
+  `$HOME/.vim/after/ftplugin/tex.vim:` >vim
+
+    map <buffer> K <Plug>(vimtex-doc-package)
+
+* Use a custom function in your |vimrc| file, something like this: >vim
+
+    nnoremap <silent> K :call <sid>show_documentation()<cr>
+    function! s:show_documentation()
+      if index(['vim', 'help'], &filetype) >= 0
+        execute 'help ' . expand('<cword>')
+      elseif &filetype ==# 'tex'
+        VimtexDocPackage

+
+nvim-cmp with cmp-vimtex ~
+
+`cmp-vimtex` is a dedicated `nvim-cmp` extension that gives some extra
+benefits compared to the more general `cmp-omni`:
+
+* Allows fuzzy matching against all info provided by Vimtex (including
+  bibliographic details, useful for citations).
+* Parses and display all details contained in bibtex files for cite
+  completions.
+* Trims long strings in the completion menu (to add space for the documentation
+  window).
+* Triggers the completion menu automatically after typing `\cite{`.
+* Allows more granular configuration of the menus, and more.
+
+To use `cmp-vimtex`, you should add something like the following to your
+configuration. For more info, check the README of the github repo ([1] above).
+>lua
+  local cmp = require('cmp')
+  cmp.setup {
+    -- global configuration goes here

+|nvim-compe| is an automatic completion plugin for Neovim. It has support for
+many different completion sources, including omni-completion. However,
+|nvim-compe| has been deprecated in favor of the more recent |nvim-cmp|, see
+|vimtex-complete-nvim-cmp|. The following configuration examples should still
+be valid for anyone who for some reason would still wish to use |nvim-compe|.
+https://github.com/hrsh7th/nvim-compe.
+
+The omni-completion source can be enabled for TeX/LaTeX files by adding `omni`
+to the completion sources and specifying the `tex` filetype. For example, in
+Lua, it should look something like this: >lua
+
+  require('compe').setup({
+      source = {
+          omni = {
+              filetypes = {'tex'},
+          },
+      },
+      -- the rest of your compe config...
+  })
+
+And in Vimscript, it should look something like this: >vim
+
+  let g:compe.source = {
+        \ 'omni': {
+        \  'filetypes': ['tex'],
+        \ }

+MUcomplete is an implementation of chained (fallback) completion, whereby
+several completion methods are attempted one after another until a result is
+returned. The plugin is available here:
+https://github.com/lifepillar/vim-mucomplete.
+
+To enable automatic completion with MUcomplete, use the following options: >vim
+
+  let g:mucomplete#can_complete = {}
+  let g:mucomplete#can_complete.tex =
+    \ { 'omni': { t -> t =~# g:vimtex#re#neocomplete . '$' } }

+
+VimTeX can fold documents according to the LaTeX structure (part, chapter,
+section and subsection).  Folding in tex files is turned off by default, but
+can be enabled if desired, either through the option |g:vimtex_fold_enabled|,
+or manually with >vim
+
+  set foldmethod=expr
+  set foldexpr=vimtex#fold#level(v:lnum)
+  set foldtext=vimtex#fold#text()
+
+The folding is mainly configured through the dictionary option
+|g:vimtex_fold_types|.
+
+Note: The |fold-expr| method of folding is well known to be slow, e.g. for
+      long lines and large files. To speed things up, the user may want to
+      enable the |g:vimtex_fold_manual| option. An alternative is to add
+      a dedicated plugin that improves folding speed for the slow fold
+      methods, e.g. https://github.com/Konfekt/FastFold.
+
+In order to get slightly cleaner fold text, I recommend setting the global
+'fillchars' option to a single space for folds: >vim
+
+  set fillchars=fold:\
+
+Note: Remember to include the whitespace after backslash!
+
+In addition, VimTeX also provides basic folding in bibtex files. This is
+disabled by default, but will be enabled if |g:vimtex_fold_enabled| is set to
+1 or |v:true|. It can also be individually configured with
+|g:vimtex_fold_bib_enabled|.
+
+Associated settings:
+* |g:vimtex_fold_enabled|

+In these modern times, a lot of people have started to rely on Tree-sitter for
+syntax highlighting (and more). Thus, it is pertinent to mention that a couple
+of the text objects rely on the syntax highlighting rules to work. See also
+|vimtex-text-objects| and |vimtex-faq-treesitter|.
+
+LaTeX is a macro expansion language and it is impossible to write a fully
+correct syntax parser without running the `tex` compiler itself. VimTeX aims
+to be pragmatic and provide a best-effort syntax highlighting - a decent trade
+off between simplicity and completeness.
+
+There will probably always be situations where the parser will fail, and in
+some cases it may be hard to "recover". It is therefore possible to manually
+activate a severely reduced syntax zone to handle such situations. The zone is
+activated with the directive `% VimTeX: SynIgnore on` and disabled with the
+similar directive `% VimTeX: SynIgnore off`, e.g.: >latex
+
+  % VimTeX: SynIgnore on
+  \catcode`\$=11
+  $
+  \catcode`\$=3
+  % VimTeX: SynIgnore off
+
+The above LaTeX code will look plain, but OK with VimTeX. Note: The directive
+is matched case insensitive, and the synonyms `enable` and `disable` may be
+used instead of `on` and `off`.
+
+Overleaf's magic comment [0] is also supported similarly as the `SynIgnore`
+method described above, i.e.: >latex
+
+  %%begin novalidate
+  \catcode`\$=11
+  $
+  \catcode`\$=3
+  %%end novalidate
+
+The VimTeX syntax plugin is loosely based on Dr Chip's syntax plugin for LaTeX
+which is shipped by default with Vim and neovim (|ft-tex-syntax|) [1]. There
+are several major differences that users may want to be aware of:
+* VimTeX syntax use different names for almost all syntax groups.
+* VimTeX syntax does not support syntax based folding.
+* VimTeX syntax does not lint `@` in commands, e.g. `\@cmd` (you should know
+  what you are doing).

+SYNTAX CONCEAL                                          *vimtex-syntax-conceal*
+
+VimTeX utilizes the |syn-conceal| feature of Vim to allow displaying commands
+like `\alpha` as `α`. That is, various elements/commands can be concealed or
+substituted with a unicode symbol.
+
+This feature is mostly enabled by default. Various types of concealments can
+be enabled/disabled with |g:vimtex_syntax_conceal|. The entire feature can be
+fully disabled with |g:vimtex_syntax_conceal_disable|.
+
+For conceals to work properly, one must set the option 'conceallevel' to 2. It
+is also good to be aware of the 'concealcursor' option.
+
+It is very important to note that not all fonts are suitable for this feature.
+That is, for this feature to work well, you should install and use a font that
+includes unicode characters. For Vim or Neovim in a terminal, this means you
+must configure your terminal to use such a font. This is, of course, an
+exercise for the reader, but here is a list of some possibly useful links:
+
+* https://www.programmingfonts.org/
+  * A convenient site to test different "programming" fonts. Not always easy
+    to see if the unicode support is good, but at least you can see examples
+    of how they look.
+* https://wiki.archlinux.org/index.php/Fonts
+  * The Arch Wiki is famous for being useful, and it does not fail. But it is
+    rather technical and of course refers to Arch Linux packages. It may still
+    be a good source of knowledge and inspiration.

+SYNTAX CORE SPECIFICATION                                  *vimtex-syntax-core*
+
+As it is relatively common for some users to customize their colorschemes, it
+is useful to describe some of the underlying "philosophy" of the syntax rules.
+Note that, for the following information to be useful, the reader should have
+at least some basic understanding of how to customize their colorschemes and
+syntax highlighting. The best resources to learn about this are:
+
+  i)   |usr_06|  "Using syntax highlighting" (READ THIS FIRST)
+  ii)  https://gist.github.com/romainl/379904f91fa40533175dfaec4c833f2f
+       "The right way to override any highlighting if you don't want to edit
+       the colorscheme file directly"
+       This is a good resource that describes how to properly customize
+       the highlighting of syntax groups on top of a basic colorscheme.
+  iii) https://github.com/lervag/vimtex/wiki/Syntax
+       This wiki page gives an example of how to customize and fine-tune
+       syntax highlighting of TeX and BibTeX files.
+  iv)  |usr_44|  "Your own syntax highlighted" (ADVANCED)
+
+The main philosophy of the VimTeX syntax plugin is to keep things simple,
+structured, and consistent. There is a small set of primitive syntax elements
+whose highlighting rules are linked to conventional highlight groups (see
+|group-name|). More specialized syntax elements are then linked to
+a corresponding primitive syntax element. This allows a user to change the
+highlighting of primitives with the effect that corresponding elements are
+automatically also updated. It is also possible to override specialized groups
+to link them to other conventional groups or set colors directly. This gives
+a high degree of flexibility with regards to customizing colorschemes for
+LaTeX files. See |vimtex-syntax-reference| for tables of the most important
+syntax groups with examples and descriptions.
+
+Most of LaTeX syntax is based around the macro expansion where forms are of
+the type `\name` + `[optional group(s)]` + `{argument group(s)}`, where there
+can often (not always) be white spaces and newlines between the elements. An
+argument group can often consist of other top level elements, but not always.
+Further, since LaTeX is designed to have very strong support for typing
+mathematical equations, there are several ways to start math mode, e.g.
+`$ ... $`, `$$ ... $$`, `\( ... \)`, `\[ ... \]`, and `\begin{equation}`
+matched with `\end{equation}`. Within math mode, there's a different subset of
+commands available, and it is common to want a slightly different highlighting
+of the math mode regions.
+
+VimTeX's syntax script is implemented to support these basic structures as
+well as a large set of more specific commands and elements. The more specific
+rules define groups whose names are more specific, and it is usually
+possible to define custom highlighting of specific commands and argument
+groups.
+
+Finally, it is useful to explain the naming scheme of specialized groups. The
+general idea can be described as follows.
+
+  `texCmd{type}`
+  `tex{type}Opt`
+  `tex{type}Arg`
+      A lot of LaTeX macros and commands are specified specifically with
+    a given number of optional and real arguments. They may also specify what
+    those arguments are. In most cases, the highlighting of `texCmd{type}` is
+    linked to `texCmd` and the highlighting of `tex{type}Opt` and
+    `tex{type}Arg` are respectively linked to `texOpt` and `texArg`. An
+    example of this scheme is `texCmdAuthor`, `texAuthorOpt`, and
+    `texAuthorArg` for `\author[...]{...}`.
+      Often, but not always, `texCmd{name}` is coupled with `tex{name}*`
+    groups. For example, `\include{...}` wants a file argument. The command is
+    matched as `texCmdInput`, but it is followed by a `texFileArg` argument
+    group.
+
+  `tex{type}Zone`
+    Some commands open specific syntax regions that have different rules. Math
+    mode is a good example. Math mode is highlighted differently, and the main
+    syntax regions are named `texMathZone*`. The `tex{type}Zone`s may
+    typically contain their own (sub)sets of syntax groups that are only
+    matched within the specific region. Another example is the inclusion of
+    nested syntax highlighting with e.g. the `minted` or `listings` packages.
+
+  `tex{type}{element}`
+    Some regions or commands include other types of elements, e.g. parameters
+    like in `\def\name #1` where `#1` is matched as `texDefParm`. For
+    completeness: `\def` is matched as `texCmdDef` and `\name` is matched as
+    `texDefArgName`.
+
+------------------------------------------------------------------------------
+SYNTAX PACKAGE SPECIFICATION                           *vimtex-syntax-packages*
+
+VimTeX provides several package specific syntax addons that provide richer
+syntax highlighting. These are built around the same principles as explained
+in |vimtex-syntax-core|.
+
+The syntax improvements for a specific package are by default loaded only if
+that package is detected in the current document (as explained in
+|vimtex-package-detection|). This generally works well when a document is
+compiled, but VimTeX may fail to detect packages for new documents or
+documents that are not compiled. It is therefore possible to configure that
+individual syntax packages should always load. One may also disable individual
+syntax packages. See |g:vimtex_syntax_packages| for a full list of which
+syntax addons exist and how to configure them.
+
+------------------------------------------------------------------------------
+SYNTAX GROUP REFERENCE                                *vimtex-syntax-reference*
+
+The following is a reference of the main syntax groups and its default
+highlighting, as well as one or more examples of what it matches. Most of the
+primitive groups are linked to conventional syntax groups as listed in
+|group-name|. In the examples, capital letters are used to indicate which
+parts are matched by the current group. For even more details, please refer to
+the code itself:
+* Core elements: The `vimtex#syntax#core#init_highlights()` function in the
+  file `/autoload/vimtex/syntax/core.vim` specifies the default highlighting
+  of the core groups.
+* Package specific groups and elements are defined in the package specific
+  scripts: `/autoload/vimtex/syntax/p/*.vim`.
+
+Note:
+* This is only a reference of the main groups. There are also other groups
+  available. See the source files for the full lists.
+* The following lists might not be always completely up to date. If you find
+  inconsistencies or errors, please open an issue.

+NAVIGATION                                                  *vimtex-navigation*
+
+Vim already has a lot of useful navigation related features, such as
+|tags-and-searches| and |include-search|. VimTeX improves the latter feature
+by setting the 'include' and 'includeexpr' options, see |vimtex-includeexpr|.
+
+VimTeX also provides a separate table-of-content feature. This works by
+parsing the LaTeX project and displaying a table of contents in a separate
+window. For more info, see |vimtex-toc|.
+
+The "engine" for collecting the table-of-content entries may also be used as
+a backend for external plugins. There are sources for |denite.nvim|, |unite.vim|
+and |fzf.vim| that should work well. The source code may be used as inspiration
+to write custom sources or sources for other, similar plugins.
+
+------------------------------------------------------------------------------
+INCLUDE EXPRESSION                                         *vimtex-includeexpr*
+
+VimTeX provides an advanced |includeexpr| that makes it possible to open
+source files for e.g. packages and documentclasses with the |gf| command. The
+implementation relies on `kpsewhich` to find the source files. Consider the
+following example: >latex
+
+  \documentclass{article}
+  \usepackage{MyLocalPackage}
+  \usepackage{SomeOtherPackage,YetAnotherPackage}
+  ...
+
+With the cursor on the documentclass name `article` or one of the package
+names, |gf| will take you to the TeX source files (typically `.cls` file for
+documentclass and `.sty` files for packages).
+
+------------------------------------------------------------------------------
+TABLE OF CONTENTS                                                  *vimtex-toc*
+
+|vimtex-toc| displays a table of contents (ToC) for the current LaTeX document.
+The ToC entries may be activated/jumped to with <cr> or <space>. There are
+currently four different "layers" of entries:
+
+* content  This is the main part and the "real" ToC
+* todo     This shows TODOs from comments and `\todo{...}` commands
+* label    This shows `\label{...}` commands
+* include  This shows included files
+
+The ToC is configured with |g:vimtex_toc_config|. One may change things from
+where the ToC window is positioned to which layers to show and more. Please
+read the option help for details.
+
+The ToC parser uses a list of matchers to parse the LaTeX project for the ToC
+entries. One may add custom matchers through the |g:vimtex_toc_custom_matchers|
+option. The syntax of a custom matcher is specified here:
+|toc_matcher_specification|.
+
+Note: By setting the `mode` configuration key to > 2, the separate ToC window
+is not opened and most of the features mentioned here will be irrelevant.
+
+One may force file input entries of the "include" type into the ToC through
+comments with the following syntax: >
+
+  % vimtex-include: /path/to/file
+
+The path may be absolute or relative. In the latter case, it will be relative
+to the current root (as printed by |:VimtexInfo|). This will add an entry in
+the ToC which makes it easy to open any file. Any file opened through the ToC
+that was included in this manner will be linked to the current VimTeX project,
+and thus the ToC and similar commands will be available, even if the file is

+Some people may want to have separate mappings for different ToC contents,
+e.g. one mapping to open a table of labels and todos and a different mapping
+to open a table of include files. This may be easily added with custom
+mappings: >vim
+
+  augroup vimtex_customization
+    autocmd!
+    autocmd FileType tex call CreateTocs()
+  augroup END
+
+  function CreateTocs()
+    let g:custom_toc1 = vimtex#toc#new({
+        \ 'layers' : ['label', 'todo'],
+        \ 'todo_sorted' : 0,
+        \ 'show_help' : 0,
+        \ 'show_numbers' : 0,
+        \ 'mode' : 4,
+        \})
+    nnoremap <silent> \ly :call g:custom_toc1.open()<cr>

+        \})
+    nnoremap <silent> \lY :call g:custom_toc2.open()<cr>
+  endfunction
+
+The `vimtex#toc#new` function takes a dictionary argument that may be used to

+                                          https://github.com/Shougo/unite.vim
+|denite.nvim| is a popular interface for many things, including outlines.
+Although VimTeX includes a simple interface for a tables of contents, it also
+makes sense to provide these as a source to |denite.nvim|. The source name is
+simply `vimtex`.
+
+|unite.vim| is the predecessor to |denite.nvim|. As for denite, there is a source
+called `vimtex`.
+
+If one prefers the |denite.nvim| or |unite.vim| source to the VimTeX interface,
+one may override the default mapping, e.g.: >vim
+
+  nnoremap <localleader>lt :<c-u>Denite vimtex<cr>
+  nnoremap <localleader>lt :<c-u>Unite vimtex<cr>

+|fzf.vim| integrates the general-purpose command-line fuzzy finder |fzf| into vim
+and neovim. Similar to the |denite.vim| and |unite.vim| source it may be used to
+quickly navigate VimTeX's built-in ToC feature. To use it, just define a
+mapping to `vimtex#fzf#run()` in your .vimrc, e.g.: >vim
+
+  nnoremap <localleader>lt :call vimtex#fzf#run()<cr>
+
+You can also choose to only show certain entry "layers", according to this
+table (see |vimtex-toc| for detailed explanation of the "layers"):
+
+  `c`:  content
+  `t`:  todo
+  `l`:  label
+  `i`:  include
+
+The default behavior is to show all layers, i.e. `'ctli'`. To only show
+`content` and `label`s use: >vim
+
+  :call vimtex#fzf#run('cl')
+
+On Windows the python package Colorama is required for colored output.
+For Linux and MacOS colors should work out-of-the-box, even without Colorama.
+
+A second argument can be passed to this function to customize the FZF options.
+It should be an object containing the parameters passed to `fzf#run()`. For
+example, if you've defined `g:fzf_layout`, then those options can be passed to
+`vimtex#fzf#run`: >vim
+
+  :call vimtex#fzf#run('ctli', g:fzf_layout)

+COMPILER                                                      *vimtex-compiler*
+
+VimTeX provides an interface to the following LaTeX compilers/compiler
+backends:
+
+* |vimtex-compiler-latexmk|   http://users.phys.psu.edu/~collins/software/latexmk-jcc
+* |vimtex-compiler-latexrun|  https://github.com/aclements/latexrun

+* |vimtex-compiler-arara|     https://github.com/cereda/arara
+* |vimtex-compiler-generic|
+
+The interface is implemented in a general way, which makes it relatively easy
+to add new compilers.
+
+Compilation is started and stopped with |:VimtexCompile| and |:VimtexStop|.
+Although, |:VimtexStop| stopping is only relevant for continuous compilations,
+and in this case, |:VimtexCompile| itself works as a toggle.  Single shot
+compilation is always available through |:VimtexCompileSS|.  The default
+mappings for these commands are listed here: |vimtex-default-mappings|.
+
+It is also possible to compile a selection of the file. To do this, one may
+either use the mapping, |<plug>(vimtex-compile-selected)|, or the command
+|:VimtexCompileSelected|.
+
+The compilers should respect the TeX program directive as described here:
+|vimtex-tex-program|, except for |vimtex-compiler-arara|, which uses its own
+set of directives and rules.
+
+Associated commands:
+* |:VimtexCompile|

+LATEXMK                                               *vimtex-compiler-latexmk*
+
+                      http://users.phys.psu.edu/~collins/software/latexmk-jcc
+> latexmk is a perl script for running LaTeX the correct number of times to
+> resolve cross references, etc; it also runs auxiliary programs (e.g.
+> bibtex). It has a number of other useful capabilities, for example to start
+> a previewer and then run latex whenever the source files are updated, so
+> that the previewer gives an up-to-date view of the document. The script runs
+> on both UNIX and MS-WINDOWS (XP, etc).
+
+`latexmk` is a compiler backend that handles recompilation of LaTeX documents
+when source files have been changed. VimTeX uses the continuous mode by
+default, but `latexmk` also allows single shot compilations. The compiler may
+be configured through the |g:vimtex_compiler_latexmk| option.
+
+If the `callback` key is enabled (it is by default and there is really no
+reason to disable it!), then compilation errors will be parsed automatically.
+This is done by utilizing the tricks explained below. Although `latexmk`
+can control viewers directly, VimTeX disables this feature with `-view=none`
+to get full control of the viewers.
+
+As stated, one may customize the `latexmk` options through
+|g:vimtex_compiler_latexmk|.  However, one may also configure `latexmk`
+explicitly through a global `~/.latexmkrc` file, or a project specific
+`.latexmkrc` file. It is important to know that command line arguments have
+priority, so one may want to use custom options if one wants to specify
+particular things in a configuration file.
+
+A particular set of options are very convenient for a good coupling between
+`latexmk` and Vim: `$compiling_cmd`, `$success_cmd`, and `$failure_cmd`. These
+options can be used to specify commands that are run by `latexmk` before and
+after compilation. They are used by VimTeX to achieve callbacks after
+compilation has finished through |vimtex#compiler#callback|.
+
+Another neat way to use these options is to use `xdotool` to change the window
+title of the viewer to indicate the compilation status: >perl
+
+  $compiling_cmd = "xdotool search --name \"%D\" " .
+                   "set_window --name \"%D compiling...\"";
+  $success_cmd   = "xdotool search --name \"%D\" " .
+                   "set_window --name \"%D OK\"";
+  $failure_cmd   = "xdotool search --name \"%D\" " .
+                   "set_window --name \"%D FAILURE\"";
+
+Note: If you define these options similar to the above `xdotool` trick and
+      still want to enable the VimTeX callbacks, then one must include
+      a semicolon at the end of the `cmd` strings so that VimTeX may append
+      safely to the options.
+
+Note: More info on `xdotool` here: https://www.semicomplete.com/projects/xdotool.

+
+`latexrun` is a compiler backend that handles recompilation of LaTeX documents
+when source files have been changed. However, it is a much simpler backend,
+and does not support e.g. continuous mode.
+
+The compiler may be configured through the |g:vimtex_compiler_latexrun| option.

+TECTONIC                                             *vimtex-compiler-tectonic*
+
+                                      https://tectonic-typesetting.github.io/
+> Tectonic is a modernized, complete, self-contained TeX/LaTeX engine, powered
+> by XeTeX and TeXLive.
+
+`tectonic` is a compiler backend that features automatic support file
+downloading along with reproducible builds and full Unicode and OpenType
+fonts support thanks to the power of XeTeX. It does not support continuous
+compilation like |vimtex-compiler-latexmk|, so the only relevant commands are
+|:VimtexCompile| to start (single shot) compilation, and
+|:VimtexCompileOutput| to see the compilation output.
+
+`tectonic` cleans up intermediate files like `.aux` and log files by default.
+However, VimTeX's backend invoke it with the flags `--keep-logs` and
+`--keep-synctex` which enables us to see the errors on the quickfix and it
+gives us synctex support. Therefore, by default, |<plug>(vimtex-clean)|
+and |:VimtexClean| clean these files.
+
+The compiler may be configured through the |g:vimtex_compiler_tectonic| option.
+
+Some users may be interested in using a custom command for running `tectonic` in
+a forced continuous mode by use of external tools like `entr` [0]. This could
+be achieved with the |vimtex-compiler-generic| interface, e.g. like this: >vim
+
+  let g:vimtex_compiler_method = 'generic'
+  let g:vimtex_compiler_generic = {
+        \ 'command': 'ls *.tex | entr -c tectonic /_ --synctex --keep-logs',

+> arara is a TeX automation tool based on rules and directives. It gives you

+
+`arara` is a TeX automation tool that uses rules and directives that are
+defined in the preamble of a LaTeX project. The user manual can be found here:
+https://ctan.uib.no/support/arara/doc/arara-manual.pdf
+
+`arara` does not do continuous compilation, so the only relevant commands are
+|:VimtexCompile| to start (single shot) compilation, and
+|:VimtexCompileOutput| to see the compilation output.
+
+The compiler may be configured through the |g:vimtex_compiler_arara| option.
+
+Note: It is not possible to directly specify an output directory from VimTeX.
+      This is a restriction caused by the design of arara. However, since one
+      may still want to specify custom output directories, VimTeX allows to
+      customize the output directory through the environment variable
+      |$VIMTEX_OUTPUT_DIRECTORY|.
+
+------------------------------------------------------------------------------
+GENERIC COMPILER                                      *vimtex-compiler-generic*
+
+There are a lot of various compiler backends for LaTeX, and it is also
+possible to simply use things like a Makefile. The generic backend allows to
+use mostly whatever you want. However, since it is a generic implementation,
+it will not be as well integrated as e.g. |vimtex-compiler-latexmk|.
+
+An example may be illuminating. Let's say you want to use a Makefile to
+compile your project. Then the following shows how to configure with the
+generic interface, including how to include a simple callback function that
+reacts to the compiler program output. >vim
+
+  function! Callback(msg)
+    " Use a regex match on the compiler output to get automatic VimtexErrors
+    " functionality. The below conditional must likely be changed to be
+    " useful, of course!
+    if a:msg =~# 'error'
+      call vimtex#compiler#callback(!vimtex#qf#inquire(b:vimtex.tex))
+    endif
+  endfunction
+
+  let g:vimtex_compiler_method = 'generic'
+  let g:vimtex_compiler_generic = {
+      \ 'command' : 'make',
+      \ 'hooks': [function('Callback')],
+      \}
+<
+See also |vimtex-compiler-tectonic| for another example that relies on the
+generic interface to run a "continuous" tectonic command.
+
+Some examples of build tools that can be used with the generic backend:
+
+* Light LaTeX Make (llmk)
+  https://ctan.org/pkg/light-latex-make
+
+  > This program is yet another build tool specific for LaTeX documents. Its
+  > aim is to provide a simple way to specify a workflow of processing LaTeX
+  > documents and encourage people to always explicitly show the right
+  > workflow for each document.
+
+* spix (Yet another TeX compilation tool: simple, human readable, no option,
+  no magic)
+  https://ctan.org/pkg/spix
+
+  > SpiX offers a way to store information about the compilation process for
+  > a tex file inside the tex file itself. Just write the commands as comments
+  > in the tex files, and SpiX will extract and run those commands.
+  >   Everything is stored in the tex file (so that you are not missing some
+  > piece of information that is located somewhere else), in a human-readable
+  > format (no need to know SpiX to understand it).

+==============================================================================
+SYNTAX CHECKING (LINTING)                                       *vimtex-lint*
+
+VimTeX provides syntax checking (linting) for TeX and BibTeX files through
+three compilers: `lacheck` [1], `chktex` [2], and `biber` [3]. These may be
+activated with the |:compiler| command, see |compiler-select|. A selected
+compiler may then be used e.g. with |:make| or |:lmake|. See the following
+text for some tips on how one may use this feature.
+
+It is possible to use more automatic linting through dedicated plugins. For
+more information, see |vimtex-af-linting|.
+
+Associated settings:
+* |g:vimtex_lint_chktex_parameters|
+* |g:vimtex_lint_chktex_ignore_warnings|
+
+------------------------------------------------------------------------------
+
+A common workflow is to utilize the |location-list| with |:lmake|:
+
+  - To lint the currently open TeX file with `lacheck`, run
+    `:compiler lacheck|lmake`
+  - To lint the currently open TeX file with `chktex`, run
+    `:compiler chktex|lmake`
+  - To lint the currently open BibTeX file with `biber`, run
+    `:compiler bibertool|lmake`
+
+After linting, the compiler or linter messages are added to the location list.
+This list may be displayed in the location-list window with |:lwindow|, and
+one may jump between the entries with |:lN| and |:lp|. To automatically open
+the location-list window after linting is finished, one may add the following
+to one's |vimrc|: >vim
+
+  augroup VimTeX
+    autocmd!
+    autocmd QuickFixCmdPost lmake lwindow
+  augroup END
+
+For convenience, one may also define a command for linting for each file type
+and add an autocmd to automatically lint on save. The following gives an
+example for `bibertool` and BibTeX, but one may of course do the same with
+`lacheck` and/or `chktex` for TeX files as well. First, add the following to
+`~/.vim/after/ftplugin/bib.vim`: >vim
+
+  command! -buffer -bang Lint compiler bibertool | lmake<bang>
+
+Then, add to `~/.vim/after/ftplugin/bib.vim`: >vim
+
+  augroup VimTeX
+    autocmd!
+    autocmd BufWrite <buffer=abuf> compiler bibertool | lmake!
+  augroup END
+
+If one minds that Vim becomes unresponsive while linting, then one may utilize
+plugins like |vim-dispatch| [4], |AsyncRun| [5] or |tasks.vim| [6]. With
+`vim-dispatch`, one may replace the `:lmake` call with `:Make`. Note that this
+may conflict with the listing of compilation errors, since `:Make` from
+`vim-dispatch` uses the quickfix window. `tasks.vim` provide `:LMake` which
+allows one to use the location list. For `AsyncRun`, one may define a custom
+`:Make` command with: >vim
+
+  command! -bang -nargs=* -complete=file Make
+          \ AsyncRun<bang> -auto=make -program=make
+
+The quickfix window that lists the linter errors and warnings can then be
+opened by |:cwindow| and they can be jumped to by |:cN| respectively |:cp|.
+
+Often, a syntax error in a BibTeX file is due to a missing comma after an
+entry. One may define a command to automatically add such missing commas, e.g.
+by adding the following lines in `~/.vim/after/ftplugin/bib.vim`: >vim
+
+  command! -buffer -range=% -bar AddMissingCommas keeppatterns
+        \ <line1>,<line2>substitute:\v([}"])(\s*\n)+(\s*\a+\s*\=):\1,\2\3:giep
+
+To call this automatically after saving a BibTeX file, add the following
+autocommand inside a proper autocommand group (e.g. `augroup VimTeX` as
+suggested above) in `~/.vim/after/ftplugin/bib.vim`: >vim
+
+  autocmd BufWrite <buffer> exe
+        \ 'normal! m`' | silent AddMissingCommas | silent! exe 'normal! g``'
+
+Finally, for more full-fledged linting in Vim, see the plug-ins mentioned in
+|vimtex-and-friends|.

+GRAMMAR CHECKING                                               *vimtex-grammar*
+
+VimTeX provides several compilers for grammar checking TeX files through the
+|compiler-select| feature in Vim. A compiler may be activated with the
+|:compiler| command (see |vimtex-lint| above for some more tips on how to use
+this feature). The selected compiler may then be used e.g. with |:make| or
+|:lmake|. As an example, one may do the following to use the |location-list|
+with a given checker: >vim
+
+  :compiler {checker}|lmake
+
+The following is a list of the available checkers:
+
+  textidote ~
+    See more details here: |vimtex-grammar-textidote|
+
+  vlty ~
+    See more details here: |vimtex-grammar-vlty|
+
+  style-check ~
+    https://github.com/nspring/style-check.git
+
+The language of the Tex file is determined by the option |'spelllang'|. This
+option can be specified in one's vimrc file, but it can also be specified in
+a |modeline| (see also the user manual section |21.6| for a gentle
+introduction to the use of modelines).
+
+Other possibilities for grammar and language checking are:
+* The LTeX project: a grammar and spell checking tool available as a language
+  server. See |vimtex-af-lsp| for more info.
+* Angry Reviewer: An off-line vim plugin for the AngryReviewer service that
+  provides style suggestions for academic and scientific text in the quickfix
+  list.

+TEXTIDOTE                                            *vimtex-grammar-textidote*
+
+The `textidote` compiler is a VimTeX wrapper over TeXtidote [1]. TeXtidote is
+a correction tool for LaTeX documents to check grammar, style, and perform
+spell checking.
+
+Configuration of the wrapper is controlled by the Vim dictionary
+|g:vimtex_grammar_textidote|. In particular, it is important to specify the
+`jar` key to the path of the executable jar file `textidote.jar`. Please note
+that if one installs `textidote` with a package manager e.g. in some common
+Linux distributions, the `.jar` file might be missing. If so, it should be
+possible to download it manually from [1]. However, before one does that, it
+can be smart to check the top lines of the installed executable, as it may be
+a simple Bash script wrapper.
+

+VLTY                                                      *vimtex-grammar-vlty*
+
+The `vlty` compiler uses the Python package `YaLafi` [1] for extracting the
+plain text and combines this with the proofreading software
+`LanguageTool` [2]. The name `vlty` comes from VimTeX + LanguageTool + YaLafi.
+
+In order to use `vlty`, you need local installations of both components. An
+archive of `LanguageTool` can be downloaded from [3]. After uncompressing at
+a suitable place, the path to it is specified as shown below. On a system like
+`Arch Linux`, `LanguageTool` may also be installed with: >sh
+
+  sudo pacman -S languagetool
+
+`YaLafi` itself can be installed with: >
+
+  pip install --user yalafi
+
+Configuration is controlled by the Vim dictionary |g:vimtex_grammar_vlty|.
+As a minimal example, one could write in |vimrc|: >vim
+
+  let g:vimtex_grammar_vlty = {'lt_directory': 'path/to/LanguageTool'}
+  set spelllang=en_gb
+
+The given directory has to contain the `LanguageTool` software, including for
+instance the file `languagetool-server.jar`. If instead `LanguageTool` is
+installed through a package manager as mentioned above, one could write: >vim
+
+  let g:vimtex_grammar_vlty = {'lt_command': 'languagetool'}
+  set spelllang=en_gb
+
+Calling `:compiler vlty` will raise an error message if some component cannot
+be found.

+
+VimTeX provides the command |:VimtexView| to open the output PDF in a desired
+viewer specified by |g:vimtex_view_method|. The command is mapped to
+`<localleader>lv` by default. The supported viewers are described in
+|vimtex-view-configuration|, which also explains how to configure them.
+
+Many viewers support synctex for navigating between the PDF and the source tex
+file. If possible, |:VimtexView| will perform forward search when the viewer
+is opened. See |vimtex-synctex| for more details.

+VIEWER CONFIGURATION                                *vimtex-view-configuration*
+
+|g:vimtex_view_method| is the main configuration variable. It allows to choose
+between a set of predefined viewers, including a generic customizable
+interface. For the predefined viewers, forward search with synctex should
+usually work without any further configuration. With the general viewer, one
+may often specify options to enable forward search. Inverse search requires
+configuration on the viewer side in most cases.
+
+The generic interface is flexible. It relies on three options:
+* |g:vimtex_view_general_viewer|
+    Specify the viewer executable.
+* |g:vimtex_view_general_options|
+    Specify the viewer options (e.g. to specify forward search configuration).
+
+The following is a list of popular PDF viewers, in alphabetic order, and how
+they can be configured to work with VimTeX.
+
+                                                           *vimtex-view-evince*
+Evince ~
+https://wiki.gnome.org/Apps/Evince
+Evince is a document viewer for viewing multiple document formats, including
+PDFs. It comes by default with Gnome.
+
+Configuration: >vim
+  let g:vimtex_view_general_viewer = 'evince'
+
+Note: Evince only supports synctex through DBus, which is not supported by
+      VimTeX. Thus VimTeX does not support forward and inverse search with
+      Evince. However, the Vim plugin `SVED` by Peter Jorgensen is reported to
+      work well in combination with VimTeX. See the plugin page [0] for more
+      information.

+MuPDF ~
+https://www.mupdf.com/
+MuPDF is a very minimalistic and quick PDF viewer. It does not support synctex
+itself, but VimTeX provides both forward and inverse search by abusing
+`xdotool`. Inverse search must be used from within VimTeX with the mapping
+|<plug>(vimtex-reverse-search)| (default mapping: `'<localleader>lr'`).
+
+One can also use |g:vimtex_view_mupdf_send_keys| to specify a set of keys that
+is sent to MuPDF on startup.
+
+Configuration: >vim
+  let g:vimtex_view_method = 'mupdf'
+
+Associated settings:
+* |g:vimtex_view_mupdf_options|
+* |g:vimtex_view_mupdf_send_keys|
+
+Note: Both forward and inverse search requires `xdotool` to work. Forward
+      search will only take you to the correct page. Inverse search will take
+      you to the line in Vim that corresponds to the first line of the current
+      page in MuPDF.
+
+Note: Viewer handling uses window title matching. If there exists another pdf
+      viewer with the same name as the current project pdf file, then there
+      might be conflicts, and so MuPDF might not work as expected.
+

+qpdfview ~
+https://launchpad.net/qpdfview
+qpdfview is a tabbed document viewer. It supports both forward and inverse
+search. The latter must be set up from within the viewer (under "Edit ->
+Settings -> Source Editor"). Use the viewer configuration as explained in
+|vimtex-synctex-inverse-search|, but note that the interpolation variables
+should be `%1` for the filename and `%2` for the line number. Inverse search
+is triggered by right clicking in the document.
+

+Sioyek is a PDF viewer designed for reading research papers and technical
+books.
+
+Configuration: >vim

+
+Inverse search should be automatically configured and work out of the box.
+VimTeX will try to pass options to Sioyek to automatically configure inverse
+search. This means that, in most cases, inverse search should work as expected
+without any further configuration. One may still be interested in learning how
+inverse-search configuration works, in which case one should read
+|vimtex-synctex-inverse-search|. The interpolation variables for Sioyek

+Skim ~

+Skim is a PDF reader and note-taker for OS X. It is designed to help you read

+file. The VimTeX implementation supports forward search and uses a callback to
+update Skim after successful compilations.
+
+Configuration: >vim
+  let g:vimtex_view_method = 'skim'
+
+To configure inverse search: Open the `Sync` tab in the settings panel in Skim
+and set the options according to your desired version of Vim. With MacVim, one
+may use the `MacVim` preset. However, it may be more convenient to use a
+`Custom` setting and configure the inverse search option as explained in
+|vimtex-synctex-inverse-search|. Note that the interpolation variables should
+be `%line` and `%file`, not `%l` and `%f`.
+
+Inverse search is activated by pressing `Shift` and `Command`, then clicking

+SumatraPDF ~
+https://www.sumatrapdfreader.org/free-pdf-reader.html
+SumatraPDF is a PDF viewer for windows that is powerful, small, portable and
+starts up very fast. It supports both forward and inverse search.
+
+Configuration: >vim
+  let g:vimtex_view_general_viewer = 'SumatraPDF'
+  let g:vimtex_view_general_options
+      \ = '-reuse-instance -forward-search @tex @line @pdf'
+
+For convenience, the above configuration is used by default on Windows if
+`SumatraPDF` is detected as executable.
+
+Inverse search must be configured under `Settings --> Options` from within
+SumatraPDF. Find the section `Set inverse search command-line` in the bottom
+and use the viewer configuration as explained in
+|vimtex-synctex-inverse-search|.
+
+Inverse search is activated with a double click in the PDF file.
+
+Note: If you want to use SumatraPDF with VimTeX from within WSL, please read
+      |vimtex-faq-sumatrapdf-wsl|.
+
+Note: There is a known issue with VimTeX + SumatraPDF when you use `xelatex`,
+      where the pdf file in SumatraPDF is not refreshed after compilation.
+      A workaround was found and posted by @Whitebeard0 here:
+      https://github.com/lervag/vimtex/issues/1410#issuecomment-506143020
+
+                                                         *vimtex-view-texshop*
+TeXShop ~
+https://pages.uoregon.edu/koch/texshop/index.html
+TeXShop is a TeX front-end program for macOS. It provides an editor (which can
+be replaced by other external editors, such as vim), a front-end to call
+TeX-related programs that process source files, and a PDF viewer with support
+for syncing between source and PDF. VimTeX supports both forward and inverse
+searches with TeXShop.
+
+Configuration: >vim
+  let g:vimtex_view_method = 'texshop'
+
+From TeXShop, inverse search is activated by `Command`-clicking in the viewer.
+Furthermore, if TeXShop's compiler front-end is used, clicking `Goto Error` in
+the console (keyboard shortcut `Command-Control-E`) will also activate inverse
+search and jump to the line containing the error in the source.
+
+To configure inverse search:
+
+1. Adjust TeXShop's preference from a terminal:  >bash
+
+     defaults write TeXShop OtherEditorSync YES
+     defaults write TeXShop UseExternalEditor -bool true
+<
+   These commands only need to be run once as they modify TeXShop's preference
+   file in `~/Library/Preferences/TeXShop.plist`, which persists through
+   sessions. While the first preference is a hidden preference and must be set
+   via a terminal command, the second can be toggled from within TeXShop's
+   preferences pane.
+
+2. Create a shell script `/usr/local/bin/othereditor` that contains a call to
+   vim as explained in |vimtex-synctex-inverse-search|. Note that the
+   interpolation variables `%l` and `%f` should be replaced by `$1` and `$2`,
+   respectively, as TeXShop will pass the line and file as the first and
+   second argument when calling the script.
+
+   The script must be executable: >bash
+
+      chmod +x /usr/local/bin/othereditor
+<
+   MacVim users should read |vimtex-faq-texshopviewer| for additional setup
+   instructions and limitations.

+                                                   *vimtex-view-zathura-simple*
+Zathura ~
+https://pwmt.org/projects/zathura/
+Zathura is, like MuPDF, a very fast and minimalistic viewer. Compared to
+MuPDF, it allows more user configuration. Zathura has full support for both
+forward and inverse search. Zathura should be straightforward to install and
+use on Linux with Xorg. It should also work on macOS and WSL, but users may
+want to consider to use either the native Skim viewer (|vimtex-view-skim|) or
+Sioyek (|vimtex-view-sioyek|). The macOS users who still want to use Zathura
+should read |vimtex-faq-zathura-macos| or |vimtex-faq-zathura-windows-wsl|.
+
+Configuration: >vim
+  " Main variant with xdotool
+  let g:vimtex_view_method = 'zathura'
+
+  " For simple variant without xdotool
+  let g:vimtex_view_method = 'zathura_simple'
+
+VimTeX will start Zathura with the `-x` argument to specify the inverse search
+options automatically. This means that, in most cases, inverse search should
+work as expected without any further configuration. One may still be
+interested in learning how inverse-search configuration works, in which case
+one should read |vimtex-synctex-inverse-search|. The interpolation variables
+for Zathura configuration are `%{line}` and `%{input}`, not `%l` and `%f`.
+
+The main variant uses `xdotool` to help avoid duplicate Zathura instances.
+However, in some environments, `xdotool` is not available. Here the simple
+variant should work well.
+
+Associated settings:
+* |g:vimtex_callback_progpath|
+* |g:vimtex_view_zathura_check_libsynctex|
+* |g:vimtex_view_zathura_options|
+
+Note: Recent versions of Zathura no longer ensures synctex support. This has
+      resulted in synctex support being dropped on some platforms, e.g. on
+      OpenSUSE, cf. https://github.com/lervag/vimtex/issues/384. A workaround
+      is to build Zathura from source manually.
+
+Note: Viewer handling uses window title matching. If there exists another pdf
+      viewer with the same name as the current project pdf file, then there
+      might be conflicts. In particular, this might affect forward/inverse
+      searching for Zathura.
+

+SYNCTEX SUPPORT                                                *vimtex-synctex*
+
+Synctex is a tool that enables synchronization of the text editor position and
+the pdf viewer position. The tool may be used to add mappings in vim to go to
+the current position in the compiled pdf document (forward search), and also
+to go from a specific position in the pdf file to the corresponding position
+in vim (inverse search).
+
+To make synctex work, it must be enabled. VimTeX enables this by default by
+passing `-synctex=1` on the command line, unless the user overrides the
+option (see the `options` key for |g:vimtex_compiler_latexmk| or
+|g:vimtex_compiler_latexrun|).
+
+Alternatively, for |vimtex-compiler-latexmk|, one can put this in one's
+`~/.latexmkrc` file: >perl
+
+  $pdflatex = 'pdflatex -synctex=1 %O %S';
+
+Forward search ~
+                                                *vimtex-synctex-forward-search*
+For supported viewers, |:VimtexView| (<localleader>lv) will issue a forward
+search if the viewer is already opened. The forward search will take you to
+the page or position in the viewer that corresponds to the current line in
+your vim session. See |g:vimtex_view_method| for a list of supported viewers.
+
+Inverse search ~
+                                                *vimtex-synctex-inverse-search*
+                                               *vimtex-synctex-backward-search*
+                                                         *:VimtexInverseSearch*
+
+In supported viewers, one may set up inverse search, which allows one to go
+directly from a selected line in the viewer (typically by double clicking with
+the mouse or something similar) to the corresponding line inside the Vim
+instance. This is sometimes also called backward search or reverse search.
+
+Inverse search relies on communicating with Vim/neovim from the viewer by use
+of shell commands executed by the viewer. It is usually configured within the
+specific viewer through an option named something like "inverse search
+command-line". The option specifies the necessary shell command to perform the
+inverse search. The target line and file are provided as interpolation
+variables. In the following, we use `%l` and `%f`, but the interpolation
+variables may be named different in some viewers (e.g. |vimtex-view-skim|).
+A typical shell command looks like this: >
+
+  vim --remote-silent +%l %f
+
+Luckily, VimTeX provides a convenience function to simplify the viewer
+configuration. The command `VimtexInverseSearch` will execute
+|vimtex#view#inverse_search| with the target line and file as arguments inside
+the desired Vim or neovim instance. The latter function is the one that really
+performs the inverse search. The combined effect is a more robust experience
+that will seamlessly handle multiple Vim or neovim instances and multiple
+VimTeX instances. The user doesn't need to worry about passing the correct
+servernames.
+
+To configure with `VimtexInverseSearch`, use: >bash
+
+  vim -v --not-a-term -T dumb -c "VimtexInverseSearch %l '%f'"
+
+  nvim --headless -c "VimtexInverseSearch %l '%f'"
+
+On Windows, the above commands may lead to an annoying command window "popup".
+This may be avoided, or at least reduced, with the following variants: >bash
+
+  cmd /c start /min "" vim -v --not-a-term -T dumb -c "VimtexInverseSearch %l '%f'"
+
+  cmd /c start /min "" nvim --headless -c "VimtexInverseSearch %l '%f'"
+
+Note: Vim users should be aware that one may need to ensure that the server is
+      really running, see |vimtex-clientserver|.
+
+Note: Many plugin managers provide mechanisms to lazy load plugins. There is
+      no need to use such a mechanism for VimTeX, and in fact, doing it will
+      prevent Vim/neovim from loading the `:VimtexInverseSearch` command.
+
+==============================================================================
+LATEX DOCUMENTATION                                           *vimtex-latexdoc*
+
+VimTeX provides the command |:VimtexDocPackage| to open documentation for
+packages and documentclasses. The command is mapped to `K` by default.
+
+For simplicity, the standard method provided by VimTeX is to look up
+documentation online through http://texdoc.net/. However, this can be
+customized with the option |g:vimtex_doc_handlers|. The option allows much
+flexibility for advanced users. For users that want to use a local `texdoc`
+installation as the main method, they may use the following config: >vim
+
+  let g:vimtex_doc_handlers = ['vimtex#doc#handlers#texdoc']
+<
+See https://www.tug.org/texdoc/doc/texdoc.pdf for more info about `texdoc`.
+
+Associated settings:
+* |g:vimtex_doc_enabled|
+* |g:vimtex_doc_confirm_single|
+* |g:vimtex_doc_handlers|
+
+In the following, I list some relevant online and offline alternatives for
+accessing LaTeX documentation. Please note that these methods are not
+integrated into VimTeX and are listed purely for the readers convenience.

+ONLINE                                                 *vimtex-latexdoc-online*
+
+I recommend the LaTeX Wikibook [0] as a good source of documentation for
+LaTeX. One should also know about the Comprehensive TeX Archive Network, or
+CTAN [1], which is the central place for all kinds of material around TeX.
+The long-existing unofficial LaTeX(2e) reference manual (latexref) can be
+found online at [2].

+OFFLINE                                               *vimtex-latexdoc-offline*
+
+One may use a more dedicated offline documentation system. On macOS, Dash [0]
+is a non-free but high-quality system. On Linux, one may use Zeal [1] or dasht
+[2], both of which access the Dash documentation sets. Zeal should also work
+well on Windows.
+
+The above systems may be accessed from vim through dash.vim [3], zeavim.vim
+[4] or vim-dasht [5], respectively. Other alternative vim plugins include
+investigate.vim [6].
+
+The unofficial LaTeX(2e) reference manual (latexref) should also be mentioned,
+since it may be easily downloaded in various formats from [7].

+CONTEXT MENU                                              *vimtex-context-menu*
+
+VimTeX provides the command |:VimtexContextMenu| to open a context menu for
+the item below the cursor. The menu allows various actions relevant to the
+current context. It is mapped by default to `<localleader>la`.
+
+The available contexts are listed below.

+CITATION CONTEXT                                      *vimtex-context-citation*
+
+When the cursor is over a citations, e.g. `\textcite{myRef}`, then the context
+menu will show choices relevant to the current citation entry. This works by
+parsing the relevant `bib` file for metadata and providing menu actions
+depending on the available metadata. The actions are only displayed when they
+are relevant.
+
+Possible actions:
+
+  Edit entry ~
+    Go to the entry location in the relevant bib file.
+
+  Show entry ~
+    Show the registered data for the current entry.
+
+  Open PDF ~
+    Open associated PDF file from the `file` key of the bib entry.

+CODE STRUCTURE                                                    *vimtex-code*
+
+The VimTeX code is based on the |autoload| feature of vim. For each new
+latex buffer, the function *vimtex#init* initializes a state variable as well
+as buffer local mappings and commands, all based on the desired options (see
+|vimtex-options|).
+
+The main init function calls `vimtex#mymodule#init_buffer` for each submodule,
+if it exists. This function should take care of defining buffer local
+mappings, commands, and autocommands.
+
+The state variable is a |Dictionary| that contains data that is specific to
+a single LaTeX project. Such a project may consist of several buffers for
+different files if the project is a multi-file project (see
+|vimtex-multi-file|). A submodule may add to the state during initialization
+with `vimtex#mymodule#init_state`, which takes the state object as a single
+argument.
+
+The command |:VimtexInfo| (mapped to <localleader>li by default) will show the
+(relevant) contents of the local state, as well as some auxiliary information
+that may be useful for debugging purposes.
+
+See also the supplementary high-level code documentation [0] for more detailed
+information about the VimTeX code.

+This is an API reference of the most useful VimTeX functions available to
+users for customization.
+
+Note: This reference is currently a work in progress!
+
+*vimtex#cite#get_entry*
+  Returns a citation entry. It takes an option `key` argument. If a `key` is
+  supplied, then the corresponding bib entry for that key is returned (a
+  |Dict|). Else it returns the entry for the key under the cursor. If no key
+  is found, an empty |Dict| is returned.
+
+*vimtex#cite#get_key*
+  Returns the citation key under the cursor. Can be useful e.g. to create
+  a function to open a citation in another progrem such as BibDesk or Zotero.
+  For example: >vim
+
+    function! OpenInBibDesk() abort
+      let l:key = vimtex#cite#get_key()
+      if empty(l:key) | return | endif
+
+      call vimtex#util#www('x-bdsk://' .. vimtex#util#url_encode(l:key))
+    endfunction
+
+*vimtex#compiler#callback*
+  Utility function to be used as a compiler callback function. Takes a single
+  argument, which is the compiler status:
+
+  1: Compilation cycle has started
+  2: Compilation complete - Success
+  3: Compilation complete - Failed
+
+  The function does several useful things based on the status, such as running
+  the |VimtexEventCompiling|, |VimtexEventCompileFailed| and
+  |VimtexEventCompileSuccess| events.
+
+*vimtex#env#get_inner*
+*vimtex#env#get_outer*
+*vimtex#env#get_all*
+  Functions that return the surrounding inner or outer environment, or all
+  surrounding environments. The return value is a dictionary with the
+  following keys:
+
+    `name`: The environment name
+    `open`: The environment opening delimiter object
+    `close`: The environment closing delimiter object
+
+  The delimiter objects contain information about the locations and arguments
+  of the corresponding `\begin{...}[...]` and `\end{...}` commands.
+
+*vimtex#env#is_inside*
+  A function that returns the start position of the `\begin{environment}` of
+  the environment name that was passed as the only mandatory argument. That
+  is, the return value is a list of two numbers: The line number and the
+  column number. These are both 0 if no surrounding environment was found.
+
+*vimtex#syntax#in*
+    `vimtex#syntax#in(name)` -> |Boolean|
+    `vimtex#syntax#in(name, line, column)` -> |Boolean|
+  Returns |v:true| if the cursor position or the specified position is inside
+  the `name`d group. `name` is a regex that is used to matched against the
+  syntax group stack.
+
+*vimtex#syntax#in_mathzone*
+    `vimtex#syntax#in_mathzone()` -> |Boolean|
+    `vimtex#syntax#in_mathzone(line, column)` -> |Boolean|
+  Returns |v:true| if the cursor position or the specified position is inside
+  a math zone.
+
+*vimtex#view#inverse_search*
+  Utility function for reverse search from pdf viewer. Takes two arguments:
+  the line number and a filename. The function runs the event
+  |VimtexEventViewReverse| at the end, which allows more user customization.

+Q: Does VimTeX support Windows?
+A: Yes. But there are some "gotchas":
+
+   * It is highly recommended to install a dedicated Perl distribution (e.g.
+     Strawberry Perl [0]).
+   * Several features rely on having executables like `latexmk` and
+     `SumatraPDF.exe` "readily available" by adding the parent directories of
+     the executables to your PATH environment variable. See [1] for more info
+     on PATH.
+   * VimTeX does not work well with the 'shell' setting set to Windows
+     PowerShell. It is therefore recommended to use the default 'shell'
+     settings. See [2] for more information.
+   * |:VimtexInfo| might fail on the first attempt to run because Windows
+     doesn't natively support UTF-8. This support can be enabled by [3]:
+     - navigating to `Control Panel/Clock and Region/Region`,
+     - going to the `Administrative` tab and clicking on the
+       `Change system locale` button,
+     - checking the box for `Use Unicode UTF-8 for worldwide language support`.
+     Note that this Windows feature is still in Beta and could cause side
+     effects on other programs. Use it with care and revert the process if you
+     encounter more trouble.

+                                                   *vimtex-faq-slow-matchparen*
+Q: Why is matching parens so slow?
+A: Because it is complicated and requires some expensive searches for matching
+   parentheses. It uses the syntax information to skip commented delimiters,
+   which is expensive. You can tune the timeout and stopline parameters for
+   the searches with |g:vimtex_delim_timeout| and |g:vimtex_delim_stopline|,
+   which may help. If it is still too slow, you can also try to use
+   vim-matchup [0], see also |vimtex-af-enhanced-matchparen|.

+Q: VimTeX provides `dse`, `dsc`, `cse`, and `csc`.  These seem to be inspired by
+   |surround.vim|.  Does VimTeX also provide the corresponding `yse` and `ysc`?
+A: The mentioned mappings are indeed inspired by |surround.vim|.  However,
+   VimTeX does not provide `ys<text-object>e` and `ys<text-object>c`.  If you use
+   |surround.vim|, then the asked for mappings may be easily added if one adds
+   the following lines to `~/.vim/after/ftplugin/tex.vim` or any other
+   `ftplugin/tex.vim` in your |runtimepath|: >vim
+
+     let b:surround_{char2nr('e')}
+         \ = "\\begin{\1environment: \1}\n\t\r\n\\end{\1\1}"
+     let b:surround_{char2nr('c')} = "\\\1command: \1{\r}"
+<
+   Remark also that, by default, |surround.vim| already provides the mapping
+   `ys<text-object>l` for encapsulating a text object in a LaTeX environment.
+
+   Note: Please also read the section |vimtex-af-surround|!
+
+   Note: An alternative is to use `vim-sandwich` (see |sandwich.txt| or
+         https://github.com/machakann/vim-sandwich), which has built-in
+         support for LaTeX-specific surroundings.

+Q: Vim throws error when jumping to file with |gf|.
+A: This might be due to the |isfname| setting, which by default contains `{,}`
+   on windows.  |isfname| is a global option, and can therefore not be set by
+   VimTeX.  Suggested solution is to remove `{,}` from |isfname| by: >vim
+
+     set isfname-={,}

+Q: How can I jump from a `\ref{label}` to the corresponding label?
+A: This is not a feature provided by VimTeX itself, but vim has very good
+   support for tag navigation, see |tags-and-searches|. It is worth mentioning
+   that the |ctags| support for LaTeX is somewhat lacking. This can be amended
+   by adding some lines to your `~/.ctags` configuration file (or
+   `.ctags.d/default.ctags` if you use Universal ctags), e.g.: >
+
+     --langdef=tex2
+     --langmap=tex2:.tex
+     --regex-tex2=/\\label[ \t]*\*?\{[ \t]*([^}]*)\}/\1/l,label/
+
+<   See [0,1] for references. I also find |gutentags| [2] to be very convenient
+   for automatically generating and updating tag files.

+Q: How can I jump from a `\cite{key}` to the corresponding bibtex entry?
+A: This is not a feature provided by VimTeX itself. Similar to
+   |vimtex-faq-tags|, the feature is available through |tags-and-searches|.
+   The following `~/.ctags` configuration will be useful (or
+   `.ctags.d/default.ctags` if you use Universal ctags): >

+     --langdef=bib
+     --langmap=bib:.bib

+Q: How can I change `TEXMFHOME`?
+A: If you change `TEXMFHOME` in your `.bashrc` or `.zshrc` or similar and use `gvim`
+   invoked from the desktop environment (from menus, hotkeys, etc.), gvim does
+   not know about the new value of `TEXMFHOME`. The reason for this is that
+   `vim` invokes shells (e.g. with `!` or `system()`) as non-interactive and
+   non-login shell, which means `.bashrc` or `.zshrc` are not read.  If you
+   start `gvim` from an interactive shell which has read `.bashrc` or `.zshrc,
+   `gvim` inherits these values and therefore they are consistent.
+
+   One can make the invoked shells interactive by setting |shellcmdflag| to
+   "-ic".  If you want to keep them non-interactive, you can create an
+   additional shell startup file where you keep your environment variables:
+
+   1. If bash is your default shell, create e.g. the file `.bashenv` containing
+      your customized `TEXMFHOME` variable and add `$BASH_ENV=$HOME/.bashenv` to
+      `$MYVIMRC` and `source $HOME/.bashenv` to `.bashrc` [0].
+
+   2. If zsh is your default shell, use `.zshenv` for customizing `TEXMFHOME`.
+      This file is always read by zsh. Nothing has to be added to `$MYVIMRC` [1].
+
+   For more information on how to correctly set environment variables, see e.g.
+   the SO answer by @Rmano [2].

+Q: Does VimTeX support WSL (the Windows Subsystem for Linux)?
+A: For the moment, rudimentarily, as follows: To set up the viewer, install
+   Sioyek [0], MuPDF [1], or SumatraPDF [2], add the executable to `%PATH%`,
+   say by Rapidee [3]. In your vimrc, the lines >vim
+
+     if has('win32') || (has('unix') && exists('$WSLENV'))
+       if executable('sioyek.exe')
+         let g:vimtex_view_method = 'sioyek'
+         let g:vimtex_view_sioyek_exe = 'sioyek.exe'
+         let g:vimtex_callback_progpath = 'wsl nvim'
+       elseif executable('mupdf.exe')
+         let g:vimtex_view_general_viewer = 'mupdf.exe'
+       elseif executable('SumatraPDF.exe')
+         let g:vimtex_view_general_viewer = 'SumatraPDF.exe'
+       endif
+     endif
+<
+   make |:VimtexView| work under Windows, and also under WSL, provided that at
+   least Windows 10 version 1903 [4] of WSL is installed, the current work dir
+   and the compiled file is contained in the Linux home directory `$HOME` (as
+   opposed to `%USERPROFILE%` in Windows).
+
+   With this configuration, both forward and inverse search should work with
+   Sioyek and neovim. However, forward search does not work for SumatraPDF. It
+   seems that, while SumatraPDF is able to find the PDF file in
+   `\\wsl$\<DistroName>\...`, the corresponding source file in
+   `\\wsl$\<DistroName>\...` is not available.
+
+   To set up a LaTeX distribution, while reusing that of Windows as proposed
+   at [5] seems efficient, in practice accessing files on mounted NTFS drives
+   from WSL is slow, even more so under WSL2 [6]. Therefore a full TeXLive
+   installation is recommended.
+
+   If only basic functionality is required, then a minimal TeXLive
+   installation, such as TinyTeX [7] or a minimal set of packages to compile
+   LaTeX as provided by your distribution, is an option, as discussed at [8].
+   For example, under openSUSE, it suffices to install the packages
+   texlive-scheme-basic, texlive-latexmk, texlive-collection-fontsrecommended.

+                                                    *vimtex-faq-sumatrapdf-wsl*
+Q: Does VimTeX work with SumatraPDF from within WSL (the Windows Subsystem for
+   Linux)?
+A: SumatraPDF expects all path arguments to be in the regular Windows format,
+   for instance `C:\Path\To\file.pdf`. When you work in WSL you will typically
+   work in a Bash shell where the corresponding path would be
+   `/mnt/c/Path/To/file.pdf`. This means SumatraPDF will not work with VimTeX
+   inside WSL without some adjustments.
+
+   Luckily, there is a CLI tool `wslpath` that can be used to translate these
+   paths. This means we can make VimTeX work with SumatraPDF from within WSL
+   by writing a simple wrapper script for SumatraPDF and using it instead.
+   Essentially, we will achieve most of the functionality we expected, except
+   backward search from SumatraPDF to VimTeX. That may also be possible, but
+   it is currently uncharted territory.
+
+   First, create a script called `sumatrapdf.sh` and put it under
+   `~/.local/bin` inside your WSL environment. You may copy the script
+   provided by @Liampor on GitHub [0] or write something similar on your own.
+   The main idea is to let the wrapper of the script do two things:
+
+   1. Convert all paths to Windows style paths with `wslpath`.
+   2. Update the Synctex file (`*.synctex.gz` ) correspondingly to allow
+      forward search.
+
+   Now, configure the viewer like this: >vim
+
+     let g:vimtex_view_general_viewer = '~/.local/bin/sumatrapdf.sh'
+     let g:vimtex_view_general_options
+           \ = '-reuse-instance -forward-search @tex @line @pdf'

+                                                     *vimtex-faq-zathura-macos*
+Q: Does Zathura + VimTeX work on macOS?
+A: Yes, it should work.  The following recipe has been reported to work [0],
+   although users with Apple Silicon CPUs have reported difficulties starting
+   `dbus`. These users may want to try the more involved recipe given in [3]
+   if the below procedure fails.
+
+   The steps assume the user has installed and knows how to use Homebrew [1].
+
+   1. Zathura needs `dbus` to work properly. Install it with the following:
+      `brew install dbus`, or, if it is already installed, reinstall (this
+      seems necessary for some unknown reason): `brew reinstall dbus`
+
+   2. The `DBUS_SESSION_BUS_ADDRESS` environment variable must be set for
+      Zathura to work with VimTeX; see [2] for details. This can be done by
+      adding the following to your `.bashrc` or `.zshrc` file (or similar): >
+
+      export DBUS_SESSION_BUS_ADDRESS="unix:path=$DBUS_LAUNCHD_SESSION_BUS_SOCKET"
+<
+   3. Changed the value of `<auth><\auth>` in
+      `/usr/local/opt/dbus/share/dbus-1/session.conf` from `EXTERNAL` to
+      `DBUS_COOKIE_SHA1`.
+
+   4. Run `brew services start dbus`, and use `brew services info dbus` to
+      double-check that `dbus` is running. Apple Silicon users that encounter
+      problems at this step should try the recipe in [3]. Also, if the user
+      encounter problems with running `dbus` with `brew services start`, they
+      could try to start it manually as explained in [4].
+
+   5. Now install Zathura (most recent version, aka HEAD): >
+
+      brew tap zegervdv/zathura
+      brew install girara --HEAD
+      brew install zathura --HEAD --with-synctex
+      brew install zathura-pdf-poppler
+      mkdir -p $(brew --prefix zathura)/lib/zathura
+      ln -s $(brew --prefix zathura-pdf-poppler)/libpdf-poppler.dylib $(brew --prefix zathura)/lib/zathura/libpdf-poppler.dylib
+<
+   6. Reboot and enjoy.
+
+   Note: If you already had Zathura and girara installed and things don't
+         work, then first uninstall and unlink them and try to follow the
+         above steps from step 1.

+Q: Does Zathura + VimTeX work on WSL2?
+A: Yes, but `systemd` or `D-Bus` must be enabled to make inverse search work
+   properly.
+
+   1. `systemd` is the default for Ubuntu 23.04 running on WSL 2. In this
+      case, there is nothing to do: Zathura and VimTeX should work fine.
+
+   2. Otherwise, if WSL version is 0.67.6 or newer, enable `systemd` by adding
+      the following content to the config file `/etc/wsl.conf` (create the
+      file if it doesn't exist). >conf
+
+        [boot]
+        systemd=true
+<
+      Then close WSL by using the command `wsl.exe --shutdown` in PowerShell to
+      restart all WSL instances [0].
+
+   3. Another approach which also works with older version of WSL consists in
+      setting up `D-Bus` daemons that can be shared in all your WSL consoles.
+      These steps are described in [1].

+Q: How does VimTeX compare to Tree-sitter?
+A: VimTeX implements a traditional syntax script for syntax highlighting of
+   LaTeX documents (see |syntax.txt|). The implementation is quite complete
+   and has support for a lot of packages. It should work well for most people.
+   See |vimtex-syntax| for detailed information.
+
+   Tree-sitter [0] is a modern library for incremental parsing of code. Neovim
+   has built-in support for Tree-sitter (see |treesitter|). With the
+   additional Tree-sitter plugin [1], one can have syntax highlighting based
+   on the Tree-sitter parser. The general benefit of this is that it should be
+   very fast, and that, for a lot of languages, it can provide high quality
+   results.
+
+   However, it is hard to write a general parser for LaTeX. This is because
+   LaTeX is a semantic language with a large amount of different commands and
+   macros from thousands of available packages, many of which makes sense to
+   highlight in a different manner. That is, we need to handle a whole lot of
+   special cases and edge cases!
+
+   Furthermore, Tree-sitter highlighting does not currently support
+   concealing, which many people find useful (see |vimtex-syntax-conceal|).
+
+   Finally, some features of VimTeX relies on the VimTeX syntax highlighting
+   to work. Examples include the math text objects (e.g. |<plug>(vimtex-a$)|
+   and |<plug>(vimtex-i$)|) as these text objects check the syntax groups to
+   determine a math region.
+
+   Thus, for people who use Tree-sitter, it is strongly advised to disable
+   Tree-sitter highlighting for LaTeX buffers. This can be done with the
+   `ignore_install` option for the setup part of `nvim-treesitter`, e.g.: >lua
+
+     require 'nvim-treesitter.configs'.setup {
+       ignore_install = { "latex" },
+       -- more stuff here
+     }
+<
+   Or, alternatively, to only disable the highlighting: >lua
+
+     require 'nvim-treesitter.configs'.setup {
+       highlight = {
+         enable = true,
+         disable = { "latex" },
+       },
+       -- more stuff here
+     }
+<
+   Of course, some people may still want to use Tree-sitter for highlighting
+   regardless of the arguments raised above. In this case, it is advised to
+   use these options for VimTeX to avoid the startup warning: >vim
+
+     let g:vimtex_syntax_enabled = 0
+     let g:vimtex_syntax_conceal_disable = 1
+<
+Q: Can I use VimTeX with Markdown plugins that need Tree-sitter enabled?
+A: Yes, it is possible by using the "additional_vim_regex_highlighting" option
+   in the `nvim-treesitter` setup (|nvim-treesitter-highlight-mod|), e.g.: >lua
+
+     require 'nvim-treesitter.configs'.setup {
+       ensure_installed = { "markdown" },
+       highlight = {
+               enable = true,
+               disable = { "latex" },
+               additional_vim_regex_highlighting = { "latex", "markdown" },
+       },
+       --other treesitter settings
+     }
+<
+   Be warned, though, that this will run both Tree-sitter and regex
+   highlighting in parallel. This negates any performance benefit, and it can
+   possibly lead to weird results since both types of highlighting are
+   applied, one over the other.

+Q: How do I set up VimTeX to work with TeXShop and MacVim (macOS)?
+A: Start by reading the section on |vimtex-view-texshop|. The examples below
+   apply to MacVim [0].
+
+   Here is an example `/usr/local/bin/othereditor` script that uses the
+   VimTeX's convenience function `VimtexInverseSearch`: >bash
+
+     #!/bin/bash
+     /usr/local/bin/mvim -v --not-a-term -T dumb -c "VimtexInverseSearch $1 '$2'"
+<
+   The call with the convenience function `VimtexInverseSearch` offers the
+   advantage that the buffer will be found if it is open, regardless of how it
+   was opened. If the buffer is not active, in a hidden tab or if the file is
+   not open at all, inverse search will fail.
+
+   As alternative, to `VimtexInverseSearch`if the .tex document was opened
+   with the `--remote-silent` option, i.e.: >bash
+
+     /usr/local/bin/mvim --remote-silent foo.tex
+<
+   the following script `/usr/local/bin/othereditor` can be used instead: >bash
+
+     #!/bin/bash
+     /usr/local/bin/mvim --remote-silent +$1 "$2"
+<
+   It will activate the buffer even if it is hidden, or open the file if it is
+   not yet loaded in any buffer.
+
+   The TeXShop release notes for versions 4.24 and 4.25 contain information
+   about backward searches with external editors in general [1].

+TROUBLESHOOTING                                       *vimtex-troubleshooting*
+
+Here are some pitfalls that one may experience if one of these assumptions are
+broken:
+
+- Completion may not work properly for exotic file encodings, such as for
+  UTF-16LE (see https://github.com/lervag/vimtex/issues/615)
+
+With different operating systems and different plugin configurations, there
+are a few things that must be considered for system interoperability. A number
+of common problems and suggested solutions are included in the following
+troubleshooting section.
+
+Problem: Continuous compilation seems to hang ~
+
+Upon starting continuous compilation the status bar indicates "VimTeX:
+Compiler started in continuous mode", but the compilation never terminates and
+the quickfix window does not load.
+
+Tips:
+1. Ensure that a latexmk process and a Perl process have started. If they have
+   not been started, then these two programs may not accessible given your
+   operating system's PATH environment variable.
+2. Ensure that the option `-interaction=nonstopmode` is provided to latexmk.
+   This is done by default by VimTeX, unless the user provides custom options
+   through |g:vimtex_compiler_latexmk| (see the `options` key). In the latter
+   case, the user must ensure that the said option is also provided.
+
+Problem: Text objects on Windows ~
+
+In Windows, environment text object commands, like `vae` and `vie`, do not
+select the entire body of the environment. More specifically, given: >latex
+
+  \begin{someenv}
+    some content
+  \end{someenv}
+
+The command `dae` results in: >
+
+  }
+
+and `die` results in: >latex
+
+  \begin{someenv}
+    t
+  \end{someenv}
+
+Solution: It seems that vim for Windows comes with some options set by default
+in the vimrc file. One of these has been reported to be `:behave mswin` (see
+|:behave|) which, among other things, sets the 'selection' option to
+"exclusive". This can be ameliorated by pursuing one of two options:
+
+1. Add `:behave xterm` to your vimrc file.
+2. Add `:set selection=inclusive` to your vimrc file.
+
+See also: https://github.com/lervag/vimtex/issues/408
+
+Problem: Typing <Tab> or <C-n> causes Vim to hang before making a completion ~
+
+VimTeX may be scanning included files with `kpsewhich` while collecting
+completion candidates for keyword completion. Try disabling this feature by
+setting |g:vimtex_include_search_enabled| to 0 in your |vimrc|: >vim
+
+  let g:vimtex_include_search_enabled = 0
+
+Note: Plugins like |supertab| [0], which often maps the |i_<Tab>| key, will
+      typically use keyword completion "behind the scenes" to gather
+      completion candidates.

+CHANGELOG                                                    *vimtex-changelog*
+
+The following changelog only logs particularly important changes, such as
+changes that break backwards compatibility.  See the git log for the detailed
+changelog.
+
+2022-11-06: Better main file detection algorithm ~
+The detection whether a file is a main file has seen gradual improvements. In
+course of this, *g:vimtex_disable_recursive_main_file_detection* has been
+removed.
+
+2021-10-25: Better inverse search ~
+Deprecate *g:vimtex_compiler_progname* as it is no longer necessary.
+
+2021-10-09: Better options for syntax conceal ~
+Deprecate *g:vimtex_syntax_conceal_default* in favor of
+|g:vimtex_syntax_conceal_disable|. The new option makes things more explicit
+and makes better sense (at least to me).
+
+2020-11-16: More flexible package syntax options ~
+Deprecate *g:vimtex_syntax_autoload_packages* in favor of
+|g:vimtex_syntax_packages|, which allows more fine grained control over each
+package.
+
+2020-09-24: More concise grammar options ~
+Deprecate *g:vimtex_textidote_jar* in favor of |g:vimtex_grammar_textidote|.
+
+2020-08-11: Remove g:vimtex_quickfix_latexlog ~
+The option *g:vimtex_quickfix_latexlog* was deprecated in favor of the more
+general mechanism provided by |g:vimtex_quickfix_ignore_filters|.
+
+2020-07-31: Use events for callback hooks ~
+The events |VimtexEventCompileSuccess|, |VimtexEventCompileFailed|, and
+|VimtexEventView| have been added to make it easier to hook personal
+customizations. This deprecates the following options:
+* *g:vimtex_compiler_callback_hooks*
+* *g:vimtex_view_general_callback*
+* *g:vimtex_view_general_hook_callback*
+* *g:vimtex_view_general_hook_view*
+* *g:vimtex_view_mupdf_hook_callback*
+* *g:vimtex_view_mupdf_hook_view*
+* *g:vimtex_view_skim_hook_callback*
+* *g:vimtex_view_skim_hook_view*
+* *g:vimtex_view_zathura_hook_callback*
+* *g:vimtex_view_zathura_hook_view*
+
+2020-07-19: Released version 1.0 ~
+Version 1.0 (and earlier) works on Vim 7.4 and with neovim 0.1.7. Later
+versions require Vim 8.0 or neovim 0.4.3.
+
+2018-08-15: Refactored the ToC interface ~
+I've made a large update to the code for the ToC window in order to simplify
+and unify the interface. In the new version, |g:vimtex_toc_config| replaces
+all of the following options:
+* *g:vimtex_index_split_width*
+* *g:vimtex_index_split_pos*
+* *g:vimtex_index_show_help*
+* *g:vimtex_index_resize*
+* *g:vimtex_index_hide_line_numbers*
+* *g:vimtex_index_mode*
+* *g:vimtex_toc_layers*
+* *g:vimtex_toc_fold*
+* *g:vimtex_toc_fold_level_start*
+* *g:vimtex_toc_hotkeys*
+* *g:vimtex_toc_refresh_always*
+* *g:vimtex_toc_show_numbers*
+* *g:vimtex_toc_tocdepth*
+
+2017-07-27: Major refactoring of the folding feature ~
+I've made a large update to the code for folding. The configuration of the
+various folded elements is now done through a single option:
+|g:vimtex_fold_types|.
+
+Deprecated options:
+* *g:vimtex_fold_comments*
+* *g:vimtex_fold_preamble*
+* *g:vimtex_fold_envs*
+* *g:vimtex_fold_env_blacklist*
+* *g:vimtex_fold_env_whitelist*
+* *g:vimtex_fold_markers*
+* *g:vimtex_fold_parts*
+* *g:vimtex_fold_sections*
+* *g:vimtex_fold_commands*
+* *g:vimtex_fold_commands_default*
+
+                                                               *vimtex-lacheck*
+2017-06-05: Removed Lacheck support ~
+Removed support for using `lacheck` for checking LaTeX syntax. The reason is
+that there exist several (good) external plugins for syntax checking files.
+These are general purpose plugins that work for multiple file types. For more
+info, see |vimtex-and-friends|.
+
+2017-05-20: Updated TOC options ~
+There's been a few updates to the TOC. During this work, I removed some
+unnecessary options.
+
+Deprecated options:
+* *g:vimtex_toc_fold_levels*  (was not necessary)
+* *g:vimtex_toc_number_width*  (see |g:vimtex_toc_tocdepth|)
+
+2017-03-31: Refactored quickfix related features ~
+I've added a more general layer for handling different error parsers.
+Currently there are few or now changes from the user point of view, but this
+should make it possible to add other methods for showing errors in a LaTeX
+project than the current one that parses the `.log` file directly.
+
+Deprecated options:
+* *g:vimtex_quickfix_warnings*  (see |g:vimtex_quickfix_latexlog|)
+
+2017-03-28: Major refactoring of initialization ~
+Added a general compiler interface, see |vimtex-compiler|.  To configure the
+`latexmk` compiler, see |g:vimtex_compiler_latexmk|.
+
+Deprecated options:
+* *g:vimtex_latexmk_enabled* (use |g:vimtex_compiler_enabled|)
+* *g:vimtex_latexmk_progname* (use |g:vimtex_compiler_progname|)
+* *g:vimtex_latexmk_callback_hooks* (use |g:vimtex_compiler_callback_hooks|)
+* *g:vimtex_latexmk_callback*
+* *g:vimtex_latexmk_autojump*
+* *g:vimtex_latexmk_continuous*
+* *g:vimtex_latexmk_background*
+* *g:vimtex_latexmk_options*
+
+Deprecated commands:
+* *VimtexCompileToggle* (use |:VimtexCompile|)
+
+2017-03-28: Major refactoring of initialization ~
+The initialization has been refactored in order to provide a more consistent
+separation of buffer initialization and state initialization. This has no
+major consequence for users, but it makes maintenance and further development
+easier.
+
+2017-03-02: Changed how to set ignored warnings ~
+I'm updating the changelog to notify of a change to the quickfix settings.
+
+Deprecated options:
+* *g:vimtex_quickfix_ignore_all_warnings*
+* *g:vimtex_quickfix_ignored_warnings*
+
+See instead:
+  |g:vimtex_quickfix_warnings|
+
+2016-05-31: A lot of things have updated ~
+I know that people would like to see a simple list of changes. Unfortunately,
+I am bad at keeping this changelog updated. All details are available in the
+git log, though. The reason I added this entry is to note that I have removed
+an option:
+
+* *g:vimtex_env_complete_list* --- It is no longer necessary. Completion
+                                 candidates are instead parsed from the
+                                 project.
+
+2016-02-06: Large refactoring of delimiter parsing ~
+I've refactored a lot of the code in order to make the parsing of delimiters
+and features that rely on delimiter detection and similar more consistent.
+This results in some changes in option names and similar, but it should make
+it easier to provide improved and more robust features.
+
+There is one feature change: The delimiter toggle now consistently toggles the
+modifier, not the delimiter itself, and it toggles between a range of
+modifiers by default. For customization, see |g:vimtex_delim_toggle_mod_list|.
+
+The following options have changed names:
+* *g:vimtex_change_set_formatexpr* ---> |g:vimtex_format_enabled|
+* *g:vimtex_change_complete_envs*  ---> |g:vimtex_env_complete_list|
+* *g:vimtex_change_toggled_delims* ---> |g:vimtex_delim_toggle_mod_list|
+
+The following options have been removed:
+* *g:vimtex_change_ignored_delims_pattern* --- It was no longer necessary
+
+The following mappings have been renamed:
+* *<plug>(vimtex-delete-env)*   ---> |<plug>(vimtex-env-delete)|
+* *<plug>(vimtex-delete-cmd)*   ---> |<plug>(vimtex-cmd-delete)|
+* *<plug>(vimtex-change-env)*   ---> |<plug>(vimtex-env-change)|
+* *<plug>(vimtex-change-cmd)*   ---> |<plug>(vimtex-cmd-change)|
+* *<plug>(vimtex-toggle-star)*  ---> |<plug>(vimtex-env-toggle-star)|
+* *<plug>(vimtex-toggle-delim)* ---> |<plug>(vimtex-delim-toggle-modifier)|
+* *<plug>(vimtex-create-cmd)*   ---> |<plug>(vimtex-cmd-create)|
+* *<plug>(vimtex-close-env)*    ---> |<plug>(vimtex-delim-close)|
+
+2015-10-19: Added convenient insert mode mappings ~
+I've merged the `math_mappings` branch (see #172 and #251). It adds the
+feature that is explained in |vimtex-imaps|.
+
+2015-06-06: Minor but convenient restructuring (++) ~
+I've changed a lot of the code structure in relatively small ways.  For
+instance, instead of referring to the particular data blobs through the global
+array, I instead linked a buffer variable to the correct global array element.
+
+One particular change is that all modules are now initialized in three steps:
+
+1. Initialize module options
+2. Initialize script variables and single execution functionalities
+3. Initialize buffer options
+
+Finally, I've cleaned up a lot of the code by removing some deprecation
+warnings and similar.
+
+2015-03-21: Implemented index buffers, deprecated vimtex_toc filetype ~
+The system for displaying the table of content relied on a dedicated filetype
+plugin.  This was inherited from LaTeX-Box, and worked quite well.  However,
+I intend to implement more functionality that uses the same kind of buffer to
+display similar things, such as a list of labels.  I realized I wanted the ToC
+window to be more adaptable, so I implemented the `index` interface for such
+buffers.  The `index` in itself may be used to create ToC-like buffers with
+simple actions.  The |vimtex-toc| uses and expands the `index` in such a way
+that the changes should barely be noticeable from the user perspective.  Note
+however the following variable name changes:
+
+* *g:vimtex_toc_numbers_width*     ---> |g:vimtex_toc_number_width|
+* *g:vimtex_toc_hide_preamble*     ---> |g:vimtex_toc_show_preamble|
+* *g:vimtex_toc_numbers*           ---> |g:vimtex_toc_show_numbers|
+
+* *g:vimtex_toc_hide_line_numbers* ---> |g:vimtex_index_hide_line_numbers|
+* *g:vimtex_toc_resize*            ---> |g:vimtex_index_resize|
+* *g:vimtex_toc_hide_help*         ---> |g:vimtex_index_show_help|
+* *g:vimtex_toc_split_pos*         ---> |g:vimtex_index_split|
+* *g:vimtex_toc_width*             -/
+
+                                                         *vim-latex-namechange*
+2015-03-08: Changed the name to VimTeX ~
+The old name `vim-latex` was already used by LaTeX-Suite.  I was not aware of
+the name clash in the beginning.  Due to the rising popularity of this plugin,
+it has become clear that such a name clash is very inconvenient.  The present
+change is therefore very much needed.
+
+The name change is reflected throughout the plugin in the names of commands,
+mappings, functions, and options.  People should update their `vimrc` settings
+accordingly.  For instance, every option name should be changed from >
+
+  g:latex_... = ...
+
+to >
+
+  g:vimtex_... = ...
+
+2014-12-07: Added more general view functionality ~
+Added new module for view functionality.  This allows more complex view
+functions (and commands), for instance to do forward (and possibly inverse)
+searching through `synctex`.  In the first version, I added forward search for
+mupdf by use of the `synctex` command and `xdotool`.
+
+The `g:latex_viewer` option has now been deprecated.  Instead one should use
+|g:vimtex_view_method| and |g:vimtex_view_general_viewer|.
+
+Deprecated option:
+* *g:latex_viewer*
+
+2014-06-13: Changed some option names ~
+Some VimTeX option names were changed in an attempt to make the names
+more consistent.  These options are listed here for reference:
+* *g:latex_errorformat_ignore_warnings*
+* *g:latex_errorformat_show_warnings*
+* *g:latex_latexmk_autojump*
+* *g:latex_latexmk_quickfix*
+
+The new names are, respectively:
+* |g:vimtex_quickfix_ignored_warnings|
+* |g:vimtex_quickfix_ignore_all_warnings|
+* |g:vimtex_quickfix_autojump|
+* |g:vimtex_quickfix_mode|
+
+2013-10-05: First public release ~
+VimTeX was first released on github on this date. The initial version was
+named vim-latex, which conflicted with Vim LaTeX-Suite which is also known as
+vim-latex.

+\section{Compiling}
+
+Press \ll to start (or stop) compiling the document.
+This turns on automatic compiling if supported by your compiler, meaning your
+document will be compiled each time you save.
+
+Press \lk to stop the compilation process
+
+Press \lc to clear auxiliary files.
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+\section{Forward and Backward Search}
+
+Press \lv to forward search. This will open the compiled PDF.
+
+Some PDF viewers support the ability to jump to the current location in the PDF.
+
+Some also support backward search (jumping from PDF to source).

+\section{Errors, Warnings and the QuickFix window}
+
+VimTeX will populate the QuickFix menu with any errors and warnings it finds in
+the log file.
+
+This is done after (attempting to) compile or pressing \le.
+
+\le also closes the QuickFix menu when it is open.
+
+\emph{Example.} Let's put some undefined commands here and compile:
+
+Moving to the QuickFix window and pressing enter on the error entry moves the
+cursor to the line containing the error. We can fix the error and continue.
+
+
+
+
+
+
+
+
+
+
+\section{Document Overview}
+
+Press \lt to show a window with a table of contents for your document.
+
+Also shows labels, references and TODOs. 
+
+Can be used to jump to sections, labels, references and TODOs.
+
+% TODO: Show table of contents.
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+\section{Motions and Text Objects}
+
+VimTeX adds various LaTeX specific motions and text objects.
+
+\emph{Example motion.} move between section boundaries with [[, [], ][ and ]].
+
+\emph{Example text object.} ic refers to a LaTeX command excluding the
+backslash. ac includes the backslash.
+
+cic: \( \alpha \)
+
+dac: \(  \)
+
+
+
+
+
+
+
+
+
+
+
+\section{Other Cool Stuff}
+
+cse changes the surrounding environment:
+
+\begin{equation}
+  v \cdot \nabla_x f_1 = -\sigma_a f_1, \quad f_1 \rvert_{\Gamma_-} = \phi(x,v).
+\end{equation}
+
+tsd toggles between () and \( \left( \right) \):
+
+\begin{equation*}
+  \frac{d}{ds} \left[ e^{\int_k^s \sigma_a(x + tv)\,dt} F_1(s) \right] = 0
+\end{equation*}
+
+tse toggles the * in environments:
+
+\begin{equation}
+  f_1(x, v) = e^{-\int_0^{\tau_-(x, v)} \sigma_a(x - sv)\,dt} \phi(x_-, v),
+\end{equation}
+
+This is only a tiny sliver of what VimTeX offers.
+Read the README for an overview, and read :h vimtex for a full description of
+all things VimTeX.

+
+This thesis considers in the first part the mathematical modelling of
+incompressible two-phase flow, in particular the calculation of interface
+curvatures and normal vectors with the level-set method.  The main contribution
+is the development of two new numerical methods that enable a more robust
+calculation of the curvature and normal vectors in areas where the gradient
+of the level-set method is discontinuous.
+
+Incompressible two-phase flow is in this thesis modelled by the Navier-Stokes
+equations with a singular source term at the interface between the phases.  The
+singular source term leads to a set of interface jump conditions.  These jump
+conditions are used in the ghost-fluid method to solve two-phase flow in
+a sharp manner.  The interface position is captured and evolved in time with
+the level-set method.  The Navier-Stokes equations for two-phase flow are
+solved with projection methods and discretized by finite differences in space
+and Runge-Kutta methods in time.  The advective terms in the governing
+equations are discretized by a weighted essentially non-oscillatory scheme.
+
+In the second part, the thesis considers the more general problem of solving
+partial-differential equations (PDEs) in complex geometries.  An extension of
+a diffuse-domain method is presented, where the accuracy is improved by adding
+a correction term.  The extension is derived for elliptic problems with Neumann
+and Robin boundary conditions.  One of the advantages of the diffuse-domain
+methods is that they allow the use of standard tools and methods because they
+are based on solving PDEs reformulated in larger and regular domains.

+\chapter{Introduction}
+This thesis considers the mathematical modelling and numerical computation of
+two-phase flows.  It focuses on developing more robust numerical methods to
+calculate the curvature and the normal vector of the interface between the two
+phases.  In addition it considers a diffuse-domain method for solving partial
+differential equations in complex geometries, and it derives an asymptotically
+second-order method for elliptic problems.
+
+\section{Background and motivation}
+Two-phase flows are particular examples of multiphase flows of gas and liquid
+with an interface that separates the two phases.  In the pedantic sense,
+two-phase flow is flow of a single fluid that occurs as two different phases,
+for example steam and water.  However, it is common to be more general, and in
+this thesis we use the term two-phase flow also for immiscible mixtures of
+different fluids, such as water and oil.
+
+Two-phase flows are crucial to a large amount of processes, both in nature and
+in industry.  Examples range from weather phenomena, such as rain drops falling
+through air, to industrial processes, for instance the separation of water from
+oil.  In general, multiphase flow phenomena influence any process where liquids
+and gases are involved.  In the oil and gas industry, most processes are
+two-phase or multiphase flow processes.  Needless to say, the understanding of
+these phenomena is fundamental in the development of new or improved processes.
+
+Consider the international trade of liquefied natural gas (LNG), which is
+a particular branch of the oil and gas industry that has undergone an
+exceptional growth in the last decades.  There is a strong focus both in Norway
+and internationally on producing LNG on large floaters
+(FLNG)\footnote{FLNG facilities do not yet exist, although a facility is under
+  development by Royal Dutch Shell~\cite{Prelude1}.  The construction of this
+  facility was started in 2012, and the first drilling is stated to commence in
+  2013~\cite{Prelude2}.}.  There are a number of both environmental and
+economic advantages of such FLNG facilities.  In particular, FLNG facilities
+would remove the need of long pipelines from the gas fields to the shore, there
+would be no requirement for compression units to pump the gas to the shore, and
+one would not need to construct onshore production facilities.  This would
+significantly reduce the environmental footprint, and would help preserve
+marine and coastal environments.  Since an FLNG facility can be moved to a new
+location when a field has been depleted, it would make it economically viable
+to open up new business opportunities to develop offshore gas fields that would
+otherwise remain stranded.
+
+Moving the LNG production to an offshore facility presents a demanding set of
+challenges.  A particular challenge is that the elements of a conventional LNG
+facility need to fit into an area roughly one quarter the original size.  Heat
+exchangers are among the main challenges in the design and operation of LNG
+plants \cite{Hesselgreaves01}.  Compact and efficient heat exchangers are
+needed to obtain an energy efficient plant with low emissions.  More optimized
+designs require more accurate tools for design and operation.  Such tools can
+only come as a result of an improved physical understanding of the complex
+two-phase flows occurring in the heat exchangers.  This can be achieved by more
+detailed mathematical modelling, together with dedicated laboratory
+observations, cf.\ \cite{Olsen07}.
+
+\section{Overview of methods for two-phase flow simulations}
+In the following, a brief overview is given of different methods for modelling
+two-phase flows where the interface location is known.  In particular, we focus
+on methods that handle the interface evolution.  For more in-depth reviews, see
+for instance \cite{Cristini04,Scardovelli99,Sethian03}.
+
+Interface propagation methods comprise a range of methods that are often
+categorised as either front tracking or front capturing.  Front-tracking
+methods use Lagrangian particles to track the interface
+explicitly~\cite{Tryggvason01}, while front-capturing methods use an Eulerian
+approach to capture the interface implicitly.  Examples of the latter are
+volume-of-fluid methods~\cite{Scardovelli99,Tryggvason11}, phase-field
+methods~\cite{Anderson98,Jacqmin99,Lowengrub98}, and level-set
+methods~\cite{Osher03}.
+
+The main advantages of front-tracking methods are their inherent accuracy and
+that topological changes do not occur without explicit action.  Hence,
+unphysical numerical reconnection does not occur.  This means that if front
+tracking is used for the simulations of two drops that collide, these drops
+will not coalesce due to numerical reconnection or merging.  However, the
+handling of topological changes are challenging, in particular in three
+dimensions~\cite{Shin02}.  Also, there are some issues of numerical
+instabilities, as discussed by \citet{Sethian85} and \citet{Osher88}.
+
+The volume-of-fluid method utilizes a volume-fraction function whose values
+represent the characteristic function of one of the fluid domains.  Its values
+are zero or one, except in those cells cut by the interface.  A considerable
+advantage of the volume-of-fluid method is that it conserves the mass of both
+fluids well.  However, the reconstruction of the interface from volume
+fractions is not simple, and computation of geometric quantities such as the
+interface curvature is not straightforward.  Also, spurious bubbles and drops
+may be created, cf.\ \cite{Lafaurie94}.
+
+The phase-field methods treat the interface in a diffuse manner, where the
+fluid properties, such as density and viscosity, change rapidly but smoothly
+across the interface.  These methods typically solve the coupled
+Cahn-Hilliard/Navier-Stokes equations, where the Cahn-Hilliard equation is
+based on the free energy of an interface~\cite{Cahn57}.  Through this energy
+formulation, one can model more advanced interface physics such as van der
+Waals interactions, electrostatic forces, and fluids with varying
+miscibilities.  However, the phase-field methods require that one resolves very
+small length scales at the interfaces.  This poses a severe restriction on the
+applicability of phase-field methods for two-phase flow, where the length
+scales of the flow are generally much larger than those of the interface.
+
+In this thesis, we have used the level-set method~\cite{Osher88}, which
+implicitly captures the interface as an isocontour of a function defined in the
+entire domain.  The main motivation of this choice is both that the level-set
+method handles topological changes of evolving interfaces automatically,
+cf.~\citet{Sethian03}, and that it is relatively straightforward to implement.
+
+It should be noted that the automatic handling of topological changes is not
+based on physical principles.  For instance, when two interfaces approach each
+other and their distance becomes less than the spacing of the grid, the
+level-set method can no longer resolve both interfaces and so they are merged.
+An important consequence is that the level-set method does not model the
+physics involved in the coalescence process, and in particular in the smaller
+scales of the film-drainage process.  This process involves a wide range of
+length scales, varying from the nanometer scale where van der Waals force are
+active to the length scales of the external flow.  Some effort has been made to
+include the effects of the smaller scales in front-capturing methods,
+cf.~\cite{Nobari96,Tryggvason10}.  Recently, \citet{Kwakkel13} presented
+a level-set/volume-of-fluid method that is coupled with a film-drainage model
+that predicts if and when two colliding droplets will coalesce.  To prevent the
+numerical coalescence, each droplet has its own locally defined level-set
+function.
+
+The level-set method has been used to model several diverse phenomena,
+such as tumour growth~\cite{Macklin06,Macklin05,Macklin08}, propagation of
+wildland fire~\cite{Mallet09}, and computer RAM production~\cite{Melicher08}.
+For a good and thorough introduction to the level-set method, see
+\cite{Osher03}.
+
+A weakness of the level-set method is that it does not conserve the mass of the
+two fluids, in particular in areas of low resolution and/or high curvature.
+Different approaches have been developed to overcome this disadvantage, for
+example the conservative level-set method~\cite{Olsson05,Olsson07}, the
+particle level-set method~\cite{Enright02}, or the coupled
+level-set/volume-of-fluid method~\cite{Sussman00}.
+
+When we use the level-set method to capture the interface for immiscible and
+incompressible two-phase flow simulations, there will be a sharp change in the
+density and viscosity across the interface.  In this thesis we use the
+ghost-fluid method~\cite{Fedkiw99}, which is a sharp-interface method where the
+jumps are included in the spatial discretizations in a sharp manner.  An
+alternative method is the continuous surface-force method introduced by
+\citet{Brackbill92}, where the density and the viscosity are smeared out across
+the interface through a smoothed Heaviside function.

+In order to do detailed theoretical studies of phenomena that are relevant for
+compact heat exchangers, we need to consider two-phase flows with mass and heat
+transfer in confined and complex geometries.  One such relevant phenomenon is
+the drop-film collision process \cite{Zhao09}.  Even when restricted to
+isothermal and immiscible flows, this simple phenomenon remains a challenge.
+When the level-set method is used to capture the interface, one must be
+particularly careful about how one calculates the interface curvature and
+normal vector.  For instance, when two drops are in near collision there is
+a kink region in the level-set function between the drops, where the gradient
+is discontinuous, see \cref{fig:curvature-problem}.  This discontinuity may
+lead to large errors in the curvature and the normal vector if it is not taken
+into account in the discretization stencils.

+
+As a step towards computing two-phase flow simulations in confined geometries,
+the thesis has considered the diffuse-domain method~\cite{Li09}.  This is
+a method where partial-differential equations in complex domains are extended
+into larger, regular domains with the use of diffuse approximations of the
+physical boundaries.  The approximations converge asymptotically to the
+original problem when the width of the diffuse boundary is reduced.  With this
+method one can use standard numerical methods to solve equations that
+incorporate complex boundaries.
+
+The main contributions of the present thesis are two new methods to calculate
+the curvature and normal vector in a robust manner with the level-set method.
+These methods are shown to yield more accurate calculations of drop-film and
+drop-drop collisions.  The methods are compared with standard methods and with
+other methods from the literature.
+
+In addition, the thesis presents an extension of a diffuse-domain method by
+a high-order correction term for the solution of elliptic problems in complex
+geometries.  New analysis provided in the thesis improves the understanding of
+the diffuse-domain method, and the derived method is shown to be more accurate
+than the existing diffuse-domain method.
+
+\section{Outline of the thesis}
+The thesis is organised as follows: \Cref{chap:two-phase-flow} gives a brief
+overview of the derivation of the governing equations for two-phase flow.  It
+includes a consideration of the fluid-fluid interface conditions and the
+derivation of a simplified jump tensor for the viscous term at the interface.
+
+\Cref{chap:numerical-methods} gives a detailed description of the numerical
+methods that are used to solve the two-phase flow equations.  In particular, it
+describes the level-set method, which is used to capture the interfaces,
+projection methods that are used to solve the Navier-Stokes equations, and the
+spatial and temporal discretization schemes.  At the end of the chapter, an
+overview of the novel discretization methods for the curvature and the normal
+vector is given.
+
+\Cref{chap:diffuse-domain} gives a short introduction to the diffuse-domain
+method for an elliptic problem with Neumann boundary conditions.  It introduces
+the high-order correction term, and shows that the new method converges
+asymptotically with second-order to the original problem.  The chapter presents
+new analysis that shows that the correction term is not necessary for
+second-order convergence.
+
+In \cref{chap:contributions} the main results of the contributed papers A--E
+are summarized, and the author's contributions are highlighted.  Finally,
+\cref{chap:conclusions} gives concluding remarks and provides an outlook for
+future work.
+
+Full-text versions of the research papers A--E are provided in the Appendices
+at the end of the thesis.

+\chapter{Governing equations for two-phase flow}
+\label{chap:two-phase-flow}
+In this chapter we will give a brief overview of the derivation of the
+governing equations for two-phase flow.  We begin with a consideration of the
+Navier-Stokes equations for single-phase flow.  We then introduce a singular
+surface-force term and derive the Navier-Stokes equations for two-phase flow.
+Finally, we use the Navier-Stokes equations for two-phase flow to derive jump
+conditions at the interface between the phases.
+
+\section{The Navier-Stokes equations for single-phase flow}
+The following is a brief derivation of the Navier-Stokes equations for
+single-phase flows.  For a more thorough derivation of these equations, see for
+instance \citet[§4 and §5]{Aris89} or \citet[Chapter~4]{White03}.
+
+We consider a single-phase, viscous flow in some domain $\Omega$ with boundary
+$\partial\Omega$.  When temperature effects are neglected the flow is described
+by the Cauchy equation
+\begin{equation}
+  \label{eq:cauchy_equation}
+  \rho\left(\cd{\vct u}\right) = \div\tenstr+\rho\vct f,
+\end{equation}
+and the mass conservation equation,
+\begin{equation}
+  \label{eq:cons_of_mass}
+  \pdt\rho + \div(\rho\vct u) = 0.
+\end{equation}
+Here $\rho$ is the fluid density, $\vct u$ is the flow velocity, $t$ is time,
+$\tenstr$ is the stress tensor, $\vct f$ denotes body forces, and $\del$ is
+used to denote the gradient and divergence operators.  The stress tensor for
+Newtonian fluids with zero bulk viscosity is
+\begin{equation}
+  \tenstr = -p\tenI + 2\mu\tenD - \frac 2 3\mu (\trace\tenD) \tenI,
+  \label{eq:viscous_stress_tensor}
+\end{equation}
+where $p$ is the pressure, $\tenI$ is the identity tensor, $\mu$ is the dynamic
+viscosity, and $\trace\tenD$ denotes the trace of the strain-rate tensor
+$\tenD$,
+\begin{equation}
+  \tenD = \frac{1}{2}\left( \grad\vct u + (\grad\vct u)^T \right).
+  \label{eq:deformation_tensor}
+\end{equation}
+For incompressible flow, the mass-conservation equation reduces to
+\begin{equation}
+  \label{eq:navier-stokes-1}
+  \div\vct u = 0,
+\end{equation}
+that is, the velocity field must be divergence free.  If we further assume that
+the viscosity is constant, then it follows that the divergence of the stress
+tensor reduces to
+\begin{equation}
+  \label{eq:stress_tensor}
+  \div\tenstr = -\grad p + \mu\lapl\vct u,
+\end{equation}
+and so the Cauchy equation \eqref{eq:cauchy_equation} becomes
+\begin{equation}
+  \rho\left(\cd{\vct u}\right) = -\grad p + \mu\lapl\vct u + \rho\vct f.
+  \label{eq:navier-stokes-2}
+\end{equation}
+Equations \eqref{eq:navier-stokes-1} and \eqref{eq:navier-stokes-2} are the
+incompressible Navier-Stokes equations for single-phase flow with constant
+viscosity.
+
+\section{The Navier-Stokes equations for two-phase flow}
+We now consider an immiscible two-phase flow of two Newtonian fluids, each with
+its own viscosity and density.  We let $\Omega_1$ and $\Omega_2$ denote the
+domains occupied by fluid 1 and fluid 2, respectively, and let the interface
+between the fluids be denoted by $\Gamma$.  Then $\Omega
+= \Omega_1\cup\Omega_2$ and $\partial\Omega
+= (\partial\Omega_1\cup\partial\Omega_2)\setminus\Gamma$ are the fluid domain
+and its boundary, respectively.  See \cref{fig:domain} for an illustration of
+a two-phase flow domain.

+  \caption{An illustration of a two-phase flow domain.  The interface $\Gamma$
+    separates the two phases $\Omega_1$ and $\Omega_2$.}
+  \label{fig:domain}
+\end{figure}
+
+The extension of the single-phase model to account for two fluids can be made
+by adding a singular surface-force term to represent the effects of surface
+tension between the fluids.  We assume that the surface tension is constant, in
+which case the singular surface force can be defined as
+\begin{equation}
+  \funssf(\vct x,t)
+  = \int_{\Gamma}\sigma\kappa\vct n\delta(\vct x - \vct x_I(\vct s))\dif\vct s,
+  \label{eq:ssf}
+\end{equation}
+where $\sigma$ is the surface tension, $\kappa$ is the local curvature, $\vct
+n$ is the normal vector, $\delta$ is the Dirac delta function, and $\vct
+x_I(\vct s)$ is a parametrisation of the interface.  Thus the Navier-Stokes
+equations for immiscible and incompressible two-phase flow are
+\begin{align}
+  \label{eq:ns1}
+  \div\vct u &= 0, \\
+  \label{eq:ns2}
+  \rho\left(\cd{\vct u}\right) &= -\grad p + \mu\lapl\vct u
+    + \rho\vct f + \funssf.
+\end{align}
+
+\section{Fluid-fluid interface conditions}
+The surface-tension force and the jump in viscosity and density across the
+interface $\Gamma$ lead to a set of interface conditions that must be satisfied
+along the interface $\Gamma$.  The following is a brief derivation of these
+conditions.
+
+First, we only consider flows where there is no mass transfer, which implies
+that
+\begin{equation}
+  \jmp{\vct u}\cdot\vct n = 0,
+\end{equation}
+where $\jmp{\cdot}$ denotes the jump at the interface, for instance $\jmp{\mu}
+= \mu_2 - \mu_1$.  Further, for viscous flows there is no slip at the
+interface, and thus the tangential velocity component of the two fluids must be
+equal at the interface,
+\begin{equation}
+  \jmp{\vct u}\cdot\vct t = 0.
+\end{equation}
+It follows that
+\begin{align}
+  \label{eq:jmpu}
+  \jmp{\vct u} &= 0, \\
+  \label{eq:jmpJut}
+  \jmp{\grad \vct u}\cdot\vct t &= 0.
+\end{align}
+The latter is a direct consequence of the former.  Both fluids are
+incompressible, which gives the trivial identity $\jmp{\div\vct u} = 0$.  If we
+use the identity
+\begin{equation}
+  \div\vct u
+    = \vct n\cdot\grad\vct u\cdot\vct n + \vct t\cdot\grad\vct u\cdot\vct t
+  \label{eq:divuident}
+\end{equation}
+together with \eqref{eq:jmpJut} we get
+\begin{equation}
+  \vct n\cdot\jmp{\grad\vct u}\cdot\vct n = 0,
+  \label{eq:jmpngradun}
+\end{equation}
+which means that the normal component of the normal derivative of the velocity
+field is continuous across the interface.  Note that in \eqref{eq:divuident}
+and in similar expressions in the following, the nabla operator is only applied
+to $\vct u$, not the normal and tangential vectors that follow.

+  \end{tikzpicture}
+  \caption{A sketch of the control volume $\Omega_\epsilon$ that covers the
+    interface, $\Gamma$.}
+  \label{fig:domain_omega_epsilon}
+\end{figure}%
+Next, we consider the conservation of momentum.  We define a control volume
+\begin{equation}
+  \Omega_{\epsilon} = \set{\vct x \in \Omega}{\min_{\vct x_I \in \Gamma}|\vct
+    x - \vct x_I| \leq \epsilon},
+\end{equation}
+where $\epsilon > 0$, see \cref{fig:domain_omega_epsilon}.  We then integrate
+the Cauchy equation \eqref{eq:cauchy_equation} with the added singular
+surface-force term over the domain~$\Omega_\epsilon$,
+\begin{multline}
+  \intoepdx{\rho\td{\vct u}}
+    = \intoepdx{\div\tenstr} + \intoepdx{\rho\vct f} \\
+      + \intoepdx{ \int_{\Gamma}\sigma\kappa\vct n\delta(\vct x - \vct
+        x_I(\vct s))\dif\vct s}.
+\end{multline}
+Here $\tdi{\vct u} = \partial\vct u/\partial t + \vct u\cdot\grad\vct u$
+denotes the convective derivative.  Now we apply the Gauss theorem and change
+the order of integration in the last term to obtain
+\begin{equation}
+  \intoepdx{\rho\td{\vct u}} = \intdoepds{\tenstr\cdot\vct n}
+    + \intoepdx{\rho\vct f} + \int_\Gamma\sigma\kappa\vct n\dif\vct s.
+\end{equation}
+If we let $\epsilon$ go to zero, the left-hand side and the second term on the
+right-hand side vanish, and we get
+\begin{equation}
+  0 = \int_\Gamma\left( \jmp{\tenstr}\cdot\vct n + \sigma\kappa\vct
+    n \right)\dif s.
+  \label{eq:stressjumpint}
+\end{equation}
+Since the derivation above is also valid for any subset of $\Omega_\epsilon$
+containing a part of $\Gamma$, \eqref{eq:stressjumpint} must hold for any part
+of $\Gamma$.  Therefore
+\begin{equation}
+  0 = \jmp{\vct T}\cdot\vct n + \sigma\kappa\vct n.
+\end{equation}
+With $\vct T = -p\vct I + 2\mu\vct D$ we finally get the interface condition
+for the stresses,
+\begin{equation}
+  \label{eq:stress_jump}
+  \jmp{p}\vct n - \jmp{2\mu\tenD}\cdot\vct n = \sigma\kappa\vct n.
+\end{equation}
+The surface tension force is seen to introduce a discontinuity in the normal
+stresses across the interface.  The tangential stresses are continuous.
+
+\section{Interface conditions for the pressure and the viscous term}
+The previous section gave a brief derivation of the interface conditions for
+immiscible and incompressible two-phase flow without mass transfer.  In order
+to use these conditions for the discretization of the Navier-Stokes equations
+\eqref{eq:ns1} and \eqref{eq:ns2}, we need to rewrite them into a more suitable
+form.  In particular, we want to find explicit expressions for the jump in the
+pressure $\jmp p$ and the viscous term $\jmp{\mu\grad\vct u}$.  The following
+derivation is based on \cite{Hansen05} and \cite{Kang00}.
+
+First, a jump condition for the pressure is obtained by taking the inner
+product of \eqref{eq:stress_jump} with the normal vector $\vct n$,
+\begin{equation}
+  \jmp p = \vct n\cdot\jmp{2\mu\tenD}\cdot\vct n + \sigma\kappa
+      = 2\jmp{\mu}\vct n\cdot \grad\vct u \cdot\vct n
+        + \sigma\kappa,
+  \label{eq:jump_pressure}
+\end{equation}
+where \eqref{eq:jmpngradun} was used for the second equality.
+
+To find the jump in the viscous term, it is first decomposed into an interface
+normal coordinate system as
+\begin{equation}
+  \begin{split}
+    \jmp{\mu\grad\vct u} &=
+  \left(\vct n\cdot\jmp{\mu\grad\vct u}\cdot\vct n\right)\vct n\otimes\vct n +
+  \left(\vct t\cdot\jmp{\mu\grad\vct u}\cdot\vct t\right)\vct t\otimes\vct t
+        \\ &\quad+
+  \left(\vct n\cdot\jmp{\mu\grad\vct u}\cdot\vct t\right)\vct n\otimes\vct t +
+  \left(\vct t\cdot\jmp{\mu\grad\vct u}\cdot\vct n\right)\vct t\otimes\vct n,
+  \end{split}
+\end{equation}
+where $\otimes$ denotes the dyadic product.  We already showed that
+$\jmp{\grad\vct u}\cdot\vct t = 0$ and $\vct n\cdot\jmp{\grad\vct u}\cdot\vct
+n = 0$, cf.\ \eqref{eq:jmpJut} and \eqref{eq:jmpngradun}, which gives
+\begin{align}
+  \vct n\cdot\jmp{\mu\grad\vct u}\cdot\vct n &=
+    \jmp{\mu}\,\vct n\cdot\grad\vct u\cdot\vct n, \\
+  \vct t\cdot\jmp{\mu\grad\vct u}\cdot\vct t &=
+    \jmp{\mu}\,\vct t\cdot\grad\vct u\cdot\vct t, \\
+  \vct n\cdot\jmp{\mu\grad\vct u}\cdot\vct t &=
+    \jmp{\mu}\,\vct n\cdot\grad\vct u\cdot\vct t.
+\end{align}
+We then take the inner product of \eqref{eq:stress_jump} with $\vct t$, which
+gives
+\begin{equation}
+  \vct t\cdot\jmp{\mu\left(\grad\vct u + (\grad\vct u)^T \right)}\cdot\vct n
+  = \vct t\cdot\jmp{\mu\grad\vct u} \cdot\vct n
+    + \jmp{\mu}\vct n\cdot\grad\vct u \cdot\vct t
+  = 0,
+\end{equation}
+or
+\begin{equation}
+  \vct t\cdot\jmp{\mu\grad\vct u}\cdot\vct n =
+    - \jmp{\mu}\vct n\cdot\grad\vct u \cdot\vct t.
+\end{equation}
+The jump in the viscous term becomes
+\begin{multline}
+  \jmp{\mu\grad\vct u} = \jmp{\mu} \Big(
+       (\vct n\cdot\grad\vct u\cdot\vct n)\vct n\otimes\vct n
+     + (\vct n\cdot\grad\vct u\cdot\vct t)\vct n\otimes\vct t \\
+     - (\vct n\cdot\grad\vct u\cdot\vct t)\vct t\otimes\vct n
+     + (\vct t\cdot\grad\vct u\cdot\vct t)\vct t\otimes\vct t \Big).
+\end{multline}
+This can be simplified further by noting that
+\begin{equation}
+  (\grad\vct u\cdot t)\otimes\vct t
+  = (\vct n\cdot\grad\vct u\cdot\vct t)\vct n\otimes\vct t
+    + (\vct t\cdot\grad\vct u\cdot\vct t)\vct t\otimes\vct t.
+\end{equation}
+Thus we obtain the expression for the jump in the viscous term that has been
+used in the present work,
+\begin{multline}
+  \jmp{\mu\grad\vct u} = \jmp{\mu} \Big(
+       (\vct n\cdot\grad\vct u\cdot\vct n)\vct n\otimes\vct n
+     - (\vct n\cdot\grad\vct u\cdot\vct t)\vct t\otimes\vct n \\
+     + (\grad\vct u\cdot\vct t)\otimes\vct t \Big).
+  \label{eq:jumptens}
+\end{multline}
+
+\section{Summary}

+Navier-Stokes equations for two-phase flow \eqref{eq:ns1} and \eqref{eq:ns2},

+tension is included as a singular source term.
+
+Fluid-fluid interface conditions have been discussed, and it has been shown how

+\chapter{Numerical methods}
+\label{chap:numerical-methods}
+This chapter describes the numerical methods that have been used in this thesis
+to solve the Navier-Stokes equations for two-phase flow.  First, a brief
+introduction to the level-set method is given, which is followed by an outline
+of the two projection methods that have been used to solve the Navier-Stokes
+equations.  The spatial and temporal discretization methods are then
+summarized, and at the end of the chapter the new methods to calculate the
+curvature and the normal vectors are presented.
+
+\section{The level-set method}
+\label{sec:level-set}
+In order to solve the Navier-Stokes equations for two-phase flow, we need to
+know the location of the interface.  The level-set method proposed by
+\citet{Osher88} allows us to capture the interface location as the zero level
+set of the level-set function $\varphi(\vct x,t)$.  The level-set function is
+typically defined as a signed-distance function,
+\begin{equation}
+  \varphi(\vct x,t) = \begin{cases}
+     d(\vct x,t) & \text{if } \vct x\in\Omega_2, \\
+    -d(\vct x,t) & \text{if } \vct x\in\Omega_1, \\
+  \end{cases}
+\end{equation}
+where $d(\vct x,t)$ is the shortest distance to the interface $\Gamma$,
+\begin{equation}
+  d(\vct x,t) = \min_{\vct x_I \in \Gamma} |\vct x - \vct x_I|.
+\end{equation}
+Thus the interface can be defined implicitly as
+\begin{equation}
+  \Gamma(t) = \set{\vct x\in\Omega}{\varphi(\vct x,t)=0},
+              \quad t\in \mathbb R^+.
+\end{equation}
+
+The position of the interface is updated by solving an advection equation for
+$\varphi$,
+\begin{equation}
+  \label{eq:ls_adeq}
+  \pdt{\varphi} + \vct{\hat u}\cdot\grad\varphi = 0,
+\end{equation}
+where $\vct{\hat u}$ is the velocity at the interface extended to the entire
+domain.  We extend the interface velocity through solving
+a velocity-extrapolation equation,
+\begin{equation}
+  \label{eq:ls_velextr}
+  \pd{\vct{\hat u}}{\tau} + S(\varphi)\vct n\cdot\grad\vct{\hat u} = 0,
+  \quad \vct{\hat u}_{\tau=0} = \vct u,
+\end{equation}
+to steady state, cf.\ \cite{Adalsteinsson99,Zhao96}.  Here $\tau$ is
+a pseudo-time and $S$ is a smeared sign function which is equal to zero at the
+interface,
+\begin{equation}
+  S(\varphi) = \frac{\varphi}{\sqrt{\varphi^2+2\Delta x^2}}.
+\end{equation}
+
+When we solve the level-set equation \eqref{eq:ls_adeq}, the non-uniform
+advection will distort the signed-distance property of the level-set function,
+and numerical dissipation error adds to this distortion.  The level-set
+function is therefore reinitialized regularly by solving
+\begin{equation}
+  \label{eq:ls_reinit}
+  \begin{split}
+    \pd{\varphi}{\tau} + S(\varphi_0)(|\grad\varphi|-1) &= 0, \\
+    \varphi(\vct x,0) &= \varphi_0(\vct x),
+  \end{split}
+\end{equation}
+to steady state as proposed by \citet{Sussman94}.  The level-set function just
+before initialization is used as the initial condition $\varphi_0$.
+
+The level-set equations \eqref{eq:ls_adeq}, \eqref{eq:ls_velextr}, and
+\eqref{eq:ls_reinit} are discretized in time and space as described in the
+following sections.  The method presented by \citet{Adalsteinsson95} is used to
+improve the computational speed.  The method is often called the narrow-band
+method, since the level-set function is only updated in a narrow band across
+the interface at each time step.
+
+One of the advantages of the level-set method is that normal vectors and
+curvatures can be readily calculated from the level-set function, that is,
+\begin{align}
+  \label{eq:norm}
+  \vct n &= \frac{\grad\varphi}{|\grad\varphi|}, \\
+  \label{eq:curv}
+  \kappa &= \div\left(\frac{\grad\varphi}{|\grad\varphi|}\right).
+\end{align}
+
+\section{Projection methods}
+\label{sec:projection-method}
+We have employed two different projection methods in this thesis to solve the
+incompressible Navier-Stokes equations for two-phase flow \eqref{eq:ns1} and
+\eqref{eq:ns2}.  Papers A, B, and C used the direct projection
+scheme~1~(DP1)~\cite{Hansen05}, and Paper D used the more standard Chorin
+projection method \cite{Chorin68}.
+
+The projection methods are a family of methods for the solution of the
+incompressible Navier-Stokes equations that are based on the Helmholtz-Hodge
+theorem.  This theorem states that an arbitrary vector field can be decomposed
+into a divergence-free part and a rotation-free part.  That is, any vector
+field $\vct a$ can be written as
+\begin{equation}
+  \vct a = \vct a' + \grad\psi,
+\end{equation}
+where $\vct a'$ is a vector with $\div\vct a' = 0$ and $\psi$ is a scalar
+potential.  The proof of this theorem can be found in for instance
+\cite[§3.44]{Aris89} or \cite{Chorin00}.
+
+\subsection{The direct projection scheme 1}
+The DP1 was developed by \citet{Hansen05} and is based on a direct application
+of the Helmholtz-Hodge theorem.  We assume that the velocity $\vct u$ is
+sufficiently smooth, and then rewrite \eqref{eq:navier-stokes-2} to get
+\begin{equation}
+  \label{eq:divFreeVel}
+  \pdt{\vct u} = \vct w - \frac{\grad p}{\rho},
+\end{equation}
+where
+\begin{equation}
+  \vct w = - (\vct u\cdot\grad)\vct u + \nu\grad^2\vct u + \vct f.
+  \label{eq:continuousRightHandVector}
+\end{equation}
+The divergence of \eqref{eq:divFreeVel} yields a Poisson equation for the
+pressure,
+\begin{equation}
+  \div\left(\frac{\grad p}{\rho}\right) = \div\vct w.
+  \label{eq:PoissonDP1}
+\end{equation}
+The DP1 scheme follows from a direct numerical discretization of the above
+equations.  First, $\vct w$ is calculated with
+\eqref{eq:continuousRightHandVector}.  Then the pressure is found by solving
+the Poisson equation \eqref{eq:PoissonDP1}.  Finally, an Euler step is used to
+solve \eqref{eq:divFreeVel}, that is,
+\begin{equation}
+  \vct u^{n+1} = \vct u^n + \Delta t\left(\vct w - \frac{\grad p}{\rho}\right).
+  \label{eq:dp1-update}
+\end{equation}
+
+\subsection{The Chorin projection method}
+The Chorin projection method was presented by \citet{Chorin68}, and is today
+one of the standard methods for solving the Navier-Stokes equations, e.g.\
+\cite{Walker12}.  The method is briefly presented in the following.
+
+Let $\Delta t$ be the time step, and consider the discretization of the
+momentum equation \eqref{eq:navier-stokes-2} with the forward Euler method,
+\begin{equation}
+  \frac{\vct u^{n+1} - \vct u^n}{\Delta t}
+  = -\vct u^n\cdot\grad\vct u^n
+    - \frac{\grad p^{n+1}}{\rho} + \frac\mu\rho\lapl\vct u^n + \vct f,
+  \label{eq:discmomeq}
+\end{equation}
+where $\vct u^n\equiv\vct u(\vct x,n\Delta t)$ and $p^n\equiv p(\vct x,n\Delta
+t)$ are assumed known at time level $n$.  Note that the pressure gradient is
+evaluated at time level $n+1$.  Next, to solve \eqref{eq:discmomeq} in two
+steps, we introduce the intermediate velocity field $\vct u^\star$,
+\begin{equation}
+  \frac{\vct u^{n+1} - \vct u^\star + \vct u^\star - \vct u^n}{\Delta t}
+  = -\vct u^n\cdot\grad\vct u^n
+    - \frac{\grad p^{n+1}}{\rho} + \frac\mu\rho\lapl\vct u^n + \vct f,
+\end{equation}
+which is chosen such that
+\begin{align}
+  \label{eq:ustar}
+  \frac{\vct u^\star - \vct u^n}{\Delta t}
+    &= -\vct u^n\cdot\grad\vct u^n + \frac\mu\rho\lapl\vct u^n + \vct f, \\
+  \label{eq:unext}
+  \frac{\vct u^{n+1} - \vct u^\star}{\Delta t} &= - \frac{\grad p^{n+1}}{\rho}.
+\end{align}
+From \eqref{eq:ustar} we get an explicit expression for $\vct u^\star$,
+\begin{equation}
+  \vct u^{\star} = \vct u^n
+    + \Delta t\left(-\vct u^n\cdot\grad\vct u^n
+        + \frac\mu\rho\,\lapl\vct u^n + \vct f\right).
+\end{equation}
+Next, the divergence of \eqref{eq:unext} and $\div\vct u^{n+1} = 0$ yields
+a Poisson equation for the pressure,
+\begin{equation}
+  \div\left(\frac{\grad p^{n+1}}{\rho}\right)
+    = \frac{\div\vct u^\star}{\Delta t}.
+  \label{eq:PoissonChorin}
+\end{equation}
+Finally, we obtain for \eqref{eq:unext}
+\begin{equation}
+  \vct u^{n+1} = \vct u^\star - \Delta t\frac{\grad p^{n+1}}{\rho}.
+  \label{eq:velcorrection}
+\end{equation}
+
+\section{Spatial discretization}
+\label{sec:x-discr}
+The governing equations \eqref{eq:ns1}, \eqref{eq:ns2}, \eqref{eq:ls_adeq},
+\eqref{eq:ls_velextr}, and \eqref{eq:ls_reinit} are discretized on a staggered
+grid~\cite{Harlow65}, where the scalar values are located at the cell centres
+and the vector values are located at the cell edges, see
+\cref{fig:staggered-grid}.  The domain boundary coincides with cell edges, and
+the fixed grid spacing is $\Delta x$ in the $x$ direction and $\Delta y$ in the
+$y$ direction.

+\end{figure}
+
+The $x$- and $y$-derivatives, divergence, and Laplacian operators are

+\begin{align}
+  \left. G_x p \right|_{i+\frac 1 2,j}
+    &= \frac{p_{i+1,j} - p_{i,j}}{\Delta x}, \\
+  \left. G_y p \right|_{i,j+\frac 1 2}
+    &= \frac{p_{i,j+1} - p_{i,j}}{\Delta y}, \\
+  \left. \vct D \cdot \vct u \right|_{i,j}

+       + \frac{p_{i,j+1} - 2p_{i,j} + p_{i,j-1}}{(\Delta y)^2},
+\end{align}
+respectively.  Here $\vct u = (u,v)$ is a vector and $p$ is a scalar.  Note
+that the gradient of a scalar is a vector and has values located at the cell
+edges.  These definitions are consistent with the staggered grid, since the
+gradient returns a vector with components defined on the cell faces, while the
+divergence and the Laplacian returns a scalar defined at the cell centres.
+
+\subsection{Advective terms}
+The advective terms, $\vct u\cdot\grad\vct u$ in the momentum equation
+\eqref{eq:ns2} and $\vct{\hat u}\cdot\grad\varphi$ in the level-set equation
+\eqref{eq:ls_adeq}, and the normal derivative $\vct n\cdot\grad\vct{\hat u}$ in
+the velocity-extrapolation equation \eqref{eq:ls_velextr} are discretized with
+the weighted essentially non-oscillatory (WENO) scheme, cf.~\cite{Fedkiw99}
+and~\cite{Jiang96}.  The WENO scheme is a high-order upwind scheme that is
+fifth-order accurate in smooth regions.  In nonsmooth regions the accuracy is
+reduced to a minimum of third order.  The following is a brief outline of the
+WENO scheme.
+
+First, when we calculate the advective term for the velocity, the vector
+components are required on all cell edges.  That is, we must interpolate the
+$x$-component of the velocity to the location of the $y$-component of the
+velocity and vice versa.  To do this we use a linear interpolation,
+\begin{align}
+  u_{i,j+\frac 1 2} &= \frac 1 4\left(
+      u_{i-\frac 1 2,j  } + u_{i-\frac 1 2,j+1}
+    + u_{i+\frac 1 2,j+1} + u_{i+\frac 1 2,j  } \right), \\
+  v_{i+\frac 1 2,j} &= \frac 1 4\left(
+      v_{i,  j-\frac 1 2} + v_{i+1,j-\frac 1 2}
+    + v_{i+1,j+\frac 1 2} + v_{i  ,j+\frac 1 2} \right).
+\end{align}
+
+Similarly, when we calculate the advective term for the level-set function
+$\varphi$, we first interpolate the velocity to the scalar grid,
+\begin{align}
+  u_{i,j} &= \frac 1 2\left( u_{i+\frac 1 2,j} + u_{i-\frac 1 2,j} \right), \\
+  v_{i,j} &= \frac 1 2\left( v_{i,j+\frac 1 2} + v_{i,j-\frac 1 2} \right).
+\end{align}
+
+We now consider the WENO scheme for the advective operator in 1D at the point
+$x_{i+\frac 1 2}$.  The scheme extends naturally to higher dimensions.  First,
+if $u_{i+\frac 1 2} = 0$, then
+\begin{equation}
+  \left. u\pd u x \right|_{i+\frac 1 2} = 0.
+\end{equation}
+Otherwise we need to calculate a set of five differences that depend on the
+upwind direction.  The differences are denoted $\Delta v_k$ for $k=1,\dots,5$.
+If $u_{i+\frac 1 2}>0$, then we calculate
+\begin{equation}
+  \Delta v_k = \frac{u_{i+\frac{2k-5} 2} - u_{i+\frac{2k-7} 2}}{\Delta x}.
+\end{equation}
+Otherwise if $u_{i+\frac 1 2}<0$, we calculate
+\begin{equation}
+  \Delta v_k = \frac{u_{i-\frac{2k-9} 2} - u_{i-\frac{2k-7} 2}}{\Delta x}.
+\end{equation}
+Next we calculate expressions for the smoothness of three substencils,
+\begin{align}
+  S_1 &= \frac{13}{12}(\Delta v_1 - 2\Delta v_2 + \Delta v_3)^2
+    + \frac 1 4 (\Delta v_1 - 4\Delta v_2 + 3\Delta v_3)^2, \\
+  S_2 &= \frac{13}{12}(\Delta v_2 - 2\Delta v_3 + \Delta v_4)^2
+    + \frac 1 4 (\Delta v_2 - \Delta v_4)^2, \\
+  S_3 &= \frac{13}{12}(\Delta v_3 - 2\Delta v_4 + \Delta v_5)^2
+    + \frac 1 4 (3\Delta v_3 - 4\Delta v_4 + \Delta v_5)^2,
+\end{align}
+where a small $S$ indicates a smooth substencil.  These smoothness factors are
+then used to compute weights for the substencils,
+\begin{equation}
+  w_k = \frac{b_k}{b_1+b_2+b_3},
+\end{equation}
+for $k = 1,2,3$, where
+\begin{equation}
+  b_1 = \frac 1 {10}\frac 1 {(\epsilon+S_1)^2},\quad
+  b_2 = \frac 6 {10}\frac 1 {(\epsilon+S_2)^2},\quad
+  b_3 = \frac 3 {10}\frac 1 {(\epsilon+S_3)^2}.
+\end{equation}
+Here $\epsilon$ is a regularization parameter that is used to avoid division by
+zero.  We have used $\epsilon = 10^{-6}$ in this work.  Finally, the WENO
+scheme for the gradient becomes
+\begin{multline}
+  \left. \pd u x \right|_{i+\frac 1 2} \simeq
+      w_1\left(\frac 1 3\Delta v_1 - \frac 7 6\Delta v_2
+        + \frac{11} 6 \Delta v_3\right) \\
+    + w_2\left(-\frac 1 6\Delta v_2 + \frac 5 6\Delta v_3
+        + \frac 1 3 \Delta v_4\right) \\
+    + w_3\left(\frac1 3\Delta v_3 + \frac 5 6\Delta v_4
+        - \frac 1 6 \Delta v_5\right).
+\end{multline}
+
+\subsection{The viscous term}
+The viscous term $\mu\lapl\vct u$ in the Navier-Stokes equations is discretized
+by standard second-order central differences using the ghost-fluid method
+(GFM)~\cite{Fedkiw99,Kang00,Liu00}.  This method includes the jump in the
+viscous term at the interface \eqref{eq:jumptens} in the discretization stencil
+in a sharp manner.
+
+In the following we present the GFM scheme in the one-dimensional case.  The
+extension to higher dimensions is straightforward.  In order to simplify the
+notation, we omit the half indices and let $k\equiv i+\frac 1 2$.  Further, we
+consider a general case where
+\begin{equation}
+  \jmp u = a_\Gamma, \qquad \jmp{\mu\pd u x} = b_\Gamma.
+\end{equation}
+For the viscous term, $a_\Gamma = 0$, cf.\ \eqref{eq:jmpu}, and $b_\Gamma$ is
+given by the jump tensor~\eqref{eq:jumptens}.  The jump tensor is calculated at
+the cell centres near the interface with the second-order central-difference
+scheme.  It is then interpolated linearly to the cell edges, from where it is
+again interpolated linearly to the interface when needed.
+
+If the interface does not cross the stencil, then the GFM scheme reduces to the
+standard second-order central-difference stencil.  Else there are four
+stencils, depending on the location of the interface.  One such interface
+configuration is sketched in \cref{fig:gfm-scheme-example}.  In all the
+stencils, $\theta$ is defined as the relative distance from the interface to
+the node on the left, for instance
+\begin{equation}
+  \theta = \frac{|\varphi_{k}|}{|\varphi_{k}| + |\varphi_{k+1}|},
+\end{equation}
+where $\varphi_k$ and $\varphi_{k+1}$ are the level-set function values
+linearly interpolated to the vector grid.  The four stencils are given below,
+where $h\equiv\Delta x$.
+\begin{enumerate}
+  \item Phase 1 is to the left and interface lies between $k$ and $k+1$:
+    \begin{align}
+      \begin{split}
+        \left.\pd{} x\left(\mu\pd u x\right)\right|_{x_k}
+          &= \frac{\hat\mu\left(u_{k+1} - u_{k}\right)
+                 - \mu_1\left(u_{k} - u_{k-1}\right)}{h^2} \\
+          &\qquad
+             - \frac{\hat\mu a_\Gamma}{h^2}

+          &= \frac{\mu_2\left(u_{k+1} - u_{k}\right)
+                - \hat\mu\left(u_{k} - u_{k-1}\right)}{h^2} \\

+      \hat\mu &= \frac{\mu_1\mu_2}{\theta\mu_2 + (1-\theta)\mu_1}.
+    \end{align}
+  \item Phase 2 is to the left and interface lies between $k$ and $k+1$:

+      \begin{split}
+        \left.\pd{} x\left(\mu\pd u x\right)\right|_{x_k}
+          &= \frac{\hat\mu\left(u_{k+1} - u_{k}\right)
+                - \mu_2\left(u_{k} - u_{k-1}\right)}{h^2} \\
+          &\qquad
+            + \frac{\hat\mu a_\Gamma}{h^2}
+            + \frac{\hat\mu b_\Gamma (1-\theta)}{\mu_1 h},
+      \end{split} \\
+      \hat\mu &= \frac{\mu_1\mu_2}{\theta\mu_1 + (1-\theta)\mu_2}.
+    \end{align}
+  \item Phase 2 is to the left and interface lies between $k-1$ and $k$:
+    \begin{align}
+      \begin{split}
+        \left.\pd{} x\left(\mu\pd u x\right)\right|_{x_k}
+          &= \frac{\mu_1\left(u_{k+1} - u_{k}\right)
+                - \hat\mu\left(u_{k} - u_{k-1}\right)}{h^2} \\

+\subsection{Pressure Poisson equation}
+\label{sec:pressure-poisson}
+The Laplace operator in the Poisson equations \eqref{eq:PoissonDP1} and
+\eqref{eq:PoissonChorin} is also discretized by standard second-order central
+differences using the GFM~\cite{Kang00,Liu00}.  The GFM was discussed in the
+previous section, where stencils were given for the viscous term in the
+one-dimensional case.  For the pressure, the stencils are the same except we
+use $p$ instead of $u$, and $1/\rho$ and $1/\hat\rho$ instead of $\mu$ and
+$\hat\mu$.  To find the jump in the pressure at the interface, $\jmp
+p = a_\Gamma$, the jump condition \eqref{eq:jump_pressure} is calculated at the
+cell centres and then interpolated to the interface.  In addition, we use that
+$b_\Gamma = 0$, which is justified by \citet[Section~3.7]{Kang00}.
+
+The resulting linear system for the pressure is solved with a solver from the
+Portable, Extensible Toolkit for Scientific Computation (PETSc)~\cite{PETSc}.
+PETSc makes available a large selection of solvers.  In most cases, we used the
+direct solver based on LU factorisation or the conjugate gradient method with
+incomplete Cholesky factorisation.  In some cases, we used the GMRES solver
+with a preconditioner, either incomplete LU factorisation or an algebraic
+multigrid method.  See \cite{PETSc} for more details and a list of available
+methods, and see for example~\cite{Iserles09} or~\cite{Saad03} for an
+introduction to linear solvers.
+
+Finally, the gradient of the pressure, used in \eqref{eq:divFreeVel} and
+\eqref{eq:velcorrection}, is also calculated with the GFM.  In one dimension,
+the stencil is
+\begin{align}
+  \left. \frac 1 \rho \pd p x\right|_{i+\frac 1 2}
+           &= \frac 1 {\hat\rho} \frac{(p_{i+1} - a_\Gamma) - p_i} h, \\
+  \hat\rho &= \theta\rho_1 + (1-\theta)\rho_2,

+\section{Temporal discretization}
+\label{sec:t-discr}
+The temporal discretization is done with the explicit strong
+stability-preserving Runge-Kutta (SSP-RK) schemes, see
+\cite{Ketcheson05,Shu88}.  The idea behind the SSP-RK schemes is to preserve
+the stability of a low-order method when it is extended to higher order.  It is
+argued in \cite{Gottlieb01} that if one extends the forward Euler method, which
+is total variation diminishing (TVD) for a suitable discretization of a scalar
+conservation law, to a non-SSP higher-order method, then overshoots may occur
+at discontinuities.
+
+An SSP-RK method can be written as a convex sum of explicit Euler steps with
+time step $\Delta t$,
+\begin{equation}
+  \mathcal E\left(x^n\right) = x^n + \Delta t \mathcal F(x^n,t^n).
+\end{equation}
+where $\mathcal F$ is the residual of the PDE to be solved.  In this thesis we
+have used two methods:  The third-order three-stage SSP-RK method~\cite{Shu88},
+\begin{equation}
+  \begin{split}
+    x^{(1)} &= \mathcal E\left(x^n\right), \\
+    x^{(2)} &= \frac 3 4 x^n + \frac 1 4\mathcal E\left(x^{(1)}\right), \\
+    x^{n+1} &= \frac 1 3 x^n + \frac 2 3\mathcal E\left(x^{(2)}\right),
+  \end{split}
+  \label{eq:ssprk33}
+\end{equation}
+and the third-order four-stage SSP-RK method~\cite{Kraaijevanger91},
+\begin{equation}
+  \begin{split}
+    x^{(1)} &= \frac 1 2 x^n + \frac 1 2\mathcal E\left(x^n\right), \\
+    x^{(2)} &= \frac 1 2 x^{(1)} + \frac 1 2\mathcal E\left(x^{(1)}\right), \\
+    x^{(3)} &= \frac 2 3 x^n + \frac 1 6 x^{(2)}
+               + \frac 1 6\mathcal E\left(x^{(2)}\right), \\
+    x^{n+1} &= \frac 1 2 x^{(3)} + \frac 1 2\mathcal E\left(x^{(3)}\right).
+  \end{split}
+  \label{eq:ssprk34}
+\end{equation}
+
+The semi-discretized velocity-extrapolation equation \eqref{eq:ls_velextr} and
+level-set reinitialization equation \eqref{eq:ls_reinit} can be written as
+systems of ordinary differential equations (ODEs) of the form
+\begin{equation}
+  \od{\vct \psi} \tau = \vct F(\vct\psi,\tau),
+\end{equation}
+where $\vct\psi$ is a vector containing the discrete variables and $\vct F$
+contains the spatially discretized terms.  The explicit Euler step becomes
+\begin{equation}
+  \mathcal E(\vct\psi^n) = \vct\psi^n + \Delta\tau \vct F(\vct\psi^n,\tau^n).
+\end{equation}
+In this thesis, these equations are solved with the third-order four-stage
+SSP-RK method \eqref{eq:ssprk34}.  The four-stage method is used because it is
+more accurate than the three-stage method.  We wanted to make sure that the
+error is mainly dominated by the spatial discretization.
+
+The semi-discretized Navier-Stokes equations \eqref{eq:navier-stokes-1} and
+\eqref{eq:navier-stokes-2} are solved together with the level-set advection
+equation \eqref{eq:ls_adeq} with the third-order three-stage SSP-RK method
+\eqref{eq:ssprk33}.  Here an explicit Euler step $\mathcal E(\vct
+u^n,\varphi^n)$ consists of the following steps:
+\begin{enumerate}
+  \item Calculate the curvature and the normal vectors from $\varphi^n$ with
+    one of the methods described in \cref{sec:curvature}.
+  \item Calculate the intermediate velocity field, either $\vct w$
+    \eqref{eq:continuousRightHandVector} or $\vct u^\star$ \eqref{eq:ustar}.
+  \item Solve the Poisson equation \eqref{eq:PoissonDP1} or
+    \eqref{eq:PoissonChorin} for the pressure as described in
+    \cref{sec:pressure-poisson}.
+  \item Correct the velocity field with either \eqref{eq:dp1-update} or
+    \eqref{eq:velcorrection}.
+  \item Advect the level-set function $\varphi^n$ with \eqref{eq:ls_adeq}.
+\end{enumerate}
+
+\section{Time step restriction}
+\label{sec:deltaT}
+We employ the Courant-Friedrich-Lewy~(CFL) condition to allow adaptive time
+stepping and to enforce stability.  The CFL condition that is used in this
+thesis is
+\begin{equation}
+  \Delta t = \frac{C}{\frac{C_c + C_v} 2
+             + \sqrt{(C_c + C_v)^2 + 4C_g^2 + 4C_s^2}},
+\end{equation}
+where the CFL restriction $C<1$, and $C_c$, $C_v$, $C_s$, and $C_g$ represent
+the contributions from the convective term, the viscous stresses, the surface
+tension, and the gravity, respectively,
+\begin{align}
+  C_c &=  \frac{\max_{i,j}|u_{i,j}|}{\Delta x}
+        + \frac{\max_{i,j}|v_{i,j}|}{\Delta y}, \\
+  C_v &= 2\max\left(\frac{\mu_1}{\rho_1},\frac{\mu_2}{\rho_2}\right)
+         \left(\frac{1}{\Delta x^2} + \frac{1}{\Delta y^2}\right), \\
+  C_s &= \sqrt{\frac{\sigma\max_{i,j}|\kappa_{i,j}|}
+                    {\max(\rho_1,\rho_2)\min(\Delta x^2,\Delta y^2)}}, \\
+  C_g &= \sqrt{\frac{|g_x|}{\Delta x} + \frac{|g_y|}{\Delta y}}.
+\end{align}
+This CFL condition is discussed in more detail by~\citet{Lervag08}, and it is
+based on the condition by \citet{Kang00}.
+
+\section{Axisymmetry}
+For axisymmetric flow, the governing equations \eqref{eq:ns1} and
+\eqref{eq:ns2} become
+\begin{equation}
+  \frac 1 r \pd{} r\left(r u\right) + \pd v z = 0,
+\end{equation}
+\begin{multline}
+  \rho\left(\pdt u + u\pd u r + v\pd u z\right) = -\pd p r \\
+    + \mu\left(\frac 1 r \pd{} r\left(r \pd u r\right)
+          + \pdd u z - \frac u {r^2}\right) + \rho f_r + {f_s}_r,
+\end{multline}
+and
+\begin{multline}
+  \rho\left(\pdt v + u\pd v r + v\pd v z\right) = -\pd p z \\
+    + \mu\left(\frac 1 r \pd{} r\left(r \pd v r\right)
+      + \pdd v z\right) + \rho f_z + {f_s}_z.
+\end{multline}
+Here $u$ and $v$ are the radial and axial velocity components, $f_r$ and $f_z$
+are the radial and axial body-force components, and ${f_s}_r$ and ${f_s}_z$ are
+the radial and axial components of the singular surface force, respectively.
+The equations are solved as explained in the previous sections.
+
+\section{Discretization of the curvature and the normal vector}
+\label{sec:curvature}
+As stated in \cref{sec:level-set}, the normal vector \eqref{eq:norm} and the
+curvature \eqref{eq:curv} can be calculated from the level-set function as
+\begin{align*}
+  \vct n &= \frac{\grad\varphi}{|\grad\varphi|}, \\
+  \kappa &= \div\left(\frac{\grad\varphi}{|\grad\varphi|}\right).
+\end{align*}
+They are typically discretized with the standard second-order
+central-difference scheme, cf.\ \cite{Kang00,Sethian03,Xu06}.  The normal
+vector is calculated at the cell edges, and the curvature is calculated at the
+grid nodes.  The curvature is then interpolated to the interface where needed
+with linear interpolation, for instance with
+\begin{equation}
+  \kappa_\Gamma = \frac{|\varphi_{i,j}|\kappa_{i+1,j}
+  + |\varphi_{i+1,k}|\kappa_{i,j}}{|\varphi_{i,j}| + |\varphi_{i+1,j}|}.
+  \label{eq:curvature-gamma}
+\end{equation}
+
+If the level-set method is used to capture non-trivial geometries, then it will
+contain kink regions, that is, areas where the gradient of the level-set
+function is discontinuous.  \Cref{fig:level-set-function} shows a simple
+example of such a kink region for a level-set function in a one-dimensional
+domain that captures two interfaces, one on each side of $x_i$.  The kink at
+$x_i$ may lead to large errors both for the curvature and the normal vector if
+one is not careful.  Errors in the curvature lead to errors in the surface
+tension force and in the pressure, which in turn lead to errors in the
+interface evolution and in the two-phase flow.  Errors in the normal vector
+affect both the calculation of the viscous jump condition and the advection of
+the interface.  If the level-set method is used to study for example
+coalescence and breakup of drops, these errors may severely affect the
+simulations.

+
+This problem was to our knowledge first described by \citet{Smereka03}, who
+increase the numerical smoothing in the curvature discretization to lessen the
+effect.  Several non-smearing approaches have subsequently been developed.
+\citet{Macklin05} used the level-set method to study tumor growth, and they
+present a one-sided direction-difference scheme for the discretization of the
+normal vector and the curvature.  Later, \citet{Macklin06} presented an
+improved geometry-aware curvature discretization, where the curvature is
+calculated based on a local least-squares parametrisation of the interface.
+
+A different approach to avoid the kinks was presented by \citet{Salac08}.  They
+used a level-set extraction technique, where an extraction algorithm was used
+to reconstruct separate level-set functions for each distinct \emph{body}.  The
+term \emph{body} is used here to denote a subset of a given phase or fluid.
+For example, in the case of two drops of water colliding in air, the water
+drops would make two distinct bodies.  One can also avoid the extraction
+algorithm altogether by use of multiple marker functions for different bodies,
+see for instance \cite{Coyajee09,Kwakkel12}.  Note, however, that the latter
+approach means that the different bodies will not coalesce unless explicit
+action is made, cf.~\cite{Kwakkel13}.  Also, both of the approaches mentioned
+here fails to handle the problem of kinks from a single body.  That is, there
+may still be kink areas due to deformed bodies, for instance bodies with thin
+filaments or tails, or bodies shaped like horse shoes.
+
+In the following, we first present the direction-difference
+scheme~\cite{Macklin05}.  We then describe the curve-fitting discretization
+method and the local level-set extraction method.
+
+\subsection{Direction-difference scheme}
+\label{sec:dds}
+The direction-difference scheme (DDS) was introduced by \citet{Macklin05}.  It
+uses a quality function to ensure that the difference stencils never cross any
+kink regions.  The DDS is used in Papers A--C to calculate the normal vectors.
+However, in Paper C it is shown that the DDS does not always yield an accurate
+approximation of the normal vector.
+
+The basic strategy is to use a combination of central differences and one-sided
+differences based on the values of a quality function,
+\begin{equation}
+  Q(\vct x) = \left| 1 - |\grad\varphi(\vct x)|\right|.
+  \label{eq:quality}
+\end{equation}
+The quality function is approximated with central differences, and is used to
+detect the areas where the level-set function differs from the signed-distance
+function.  In the following, let $Q_{i,j} \equiv Q(\vct x_{i,j})$ and define
+a parameter $\eta>0$.  This threshold parameter is tuned such that the quality
+function will detect all the kinks.
+
+The quality function is used to define a direction function,
+\begin{equation}
+  \vct D(\vct x_{i,j}) = (D_x(\vct x_{i,j}), D_y(\vct x_{i,j})),
+\end{equation}
+where
+\begin{equation}
+  D_x(\vct x_{i,j}) = \begin{cases}
+    -1 & \text{if $Q_{i-1,j}<\eta$ and $Q_{i+1,j}\geq\eta$,} \\
+     1 & \text{if $Q_{i-1,j}\geq\eta$ and $Q_{i+1,j}<\eta$,} \\
+     0 & \text{if $Q_{i-1,j}<\eta$ and $Q_{i,j}<\eta$ and $Q_{i+1,j}<\eta$,} \\
+     0 & \text{if $Q_{i-1,j}\geq\eta$ and $Q_{i,j}\geq\eta$ and
+         $Q_{i+1,j}\geq\eta$,} \\
+     4 & \text{otherwise.}
+  \end{cases}
+  \label{eq:dirfunc}
+\end{equation}
+$D_y(\vct x_{i,j})$ is defined in a similar manner.  If $D_x(\vct x_{i,j})
++ D_y(\vct x_{i,j}) > 2$, then $\vct D(\vct x_{i,j})$ is chosen as the vector
+normal to $\grad\varphi(\vct x_{i,j})$.  It is normalized, and the sign is
+chosen such that it points in the direction of the best quality.  See
+\cite{Macklin05} for more details.
+
+The DDS is then defined as
+\begin{equation}
+  \partial_x f_{i,j} = \begin{cases}
+    \frac{f_{i,j} - f_{i-1,j}}{\Delta x}    & \text{if $D_x(x_i,y_j) = -1$,} \\
+    \frac{f_{i+1,j} - f_{i,j}}{\Delta x}    & \text{if $D_x(x_i,y_j) =  1$,} \\
+    \frac{f_{i+1,j} - f_{i-1,j}}{2\Delta x} & \text{if $D_x(x_i,y_j) =  0$,}
+  \end{cases}
+  \label{eq:Ddifference}
+\end{equation}
+and similarly for $\partial_y f_{i,j}$, where $f_{i,j}$ is a piecewise smooth
+function.  The DDS is equivalent to using central differences in smooth areas
+and one-sided differences in areas close to the kinks.
+
+\subsection{Curve-fitting discretization method}
+\label{sec:curvature-curve-fitting}
+The curve-fitting discretization method (CFDM) was first presented
+in~\cite{Lervag11} and is based on the method by \citet{Macklin06}.  The main
+idea is to identify kink regions with the quality function \eqref{eq:quality},
+and to use a curve parametrisation of the closest interface to calculate the
+curvature in regions where the quality function is larger than the threshold
+parameter, $\eta$.
+
+The CFDM applied to the curvature or the normal vector at the grid point $\vct
+x_{i,j}$ can be summarized as follows.  See also \cref{fig:cfdm}, which shows
+an example of the CFDM used at $\vct x_{i,j}$.
+\begin{enumerate}
+  \item If the quality of the level-set function in the neighbourhood of $\vct
+    x_{i,j}$ is good, that is
+    \[
+      Q(\vct{x}_{n,m}) \le \eta \; \forall (n,m) \in [i-1,i+1]\times[j-1,j+1],
+    \]
+    then we use a standard discretization.  Otherwise continue to the next
+    step.
+  \item Locate the closest interface, $\Gamma$.
+  \item Find a set of points on the located interface, $\vct x_1, \dots, \vct
+    x_n \in \Gamma$.
+  \item Create a parametrisation $\vct \gamma(s)$ of the points $\vct x_1,
+    \dots, \vct x_n$.
+  \item Use the parametrisation $\vct \gamma(s)$ to calculate a local level-set
+    function.
+  \item Use a standard discretization of the local level-set function to
+    calculate the curvature or the normal vector.
+\end{enumerate}

+\subsection{Local level-set extraction method}
+\label{sec:lolex}
+The local level-set extraction (LOLEX) method is based on the method presented
+by \citet{Salac08}, here called the SLM.  It was found that the latter method
+was insufficient, because it did not treat all the kink problems.  The LOLEX
+method is therefore a further development of the SLM, in that it handles the
+kink regions in a more general manner.
+
+The LOLEX method applied to the curvature or the normal vector at a grid point
+$\vct x_{i,j}$ is summarized by the following algorithm.  The algorithm is
+presented with 2D notation for clarity, and extends easily to 3D.  See also
+\cref{fig:lolex}, which gives a simple example of the procedure.
+\begin{enumerate}
+  \item If the quality in the neighbourhood of $\vct x_{i,j}$ is good, that is
+    \[
+      Q(\vct{x}_{n,m}) \le \eta \; \forall (n,m) \in [i-1,i+1]\times[j-1,j+1],
+    \]
+    then we use a standard discretization.  Otherwise continue to the next
+    step.
+  \item Copy a small, local square centred around $\vct x_{i,j}$ from the
+    level-set function $\varphi$ into a local array $\varphi_\text{loc}$.
+  \item Identify and enumerate all the \emph{bodies} in the local array
+    $\varphi_\text{loc}$.  A \emph{body} is here defined as a set of
+    neighbouring points where $\varphi_\text{loc}<0$, see \cref{fig:lolex}.
+    There will be $n\geq 0$ bodies in any given $\varphi_\text{loc}$ array.
+  \item If no body is identified, that is, if $n=0$, then use a standard
+    discretization with the global level-set function $\varphi$.  Otherwise
+    continue to the next step.
+  \item For each body $n$, extract the relevant parts of $\varphi_\text{loc}$
+    into an array $\varphi_\text{loc}^n$.  If necessary, extrapolate values to
+    ghost cells.
+  \item For each body, $n$, reinitialize $\varphi_\text{loc}^n$.
+  \item At this step, all the bodies in the local grid have their own
+    local level-set functions that have been reinitialized to proper
+    signed-distance functions.  Due to the separation of the bodies, there
+    are no longer any kinks.
+  \item Use the standard discretization of the curvature and the normal
+    vector at the local level-set function that represents the body that is
+    closest to $\vct x_{i,j}$.

+\chapter{The diffuse-domain approach}
+\label{chap:diffuse-domain}
+In the previous chapters, we have considered the modelling of two-phase flows,
+and in particular methods for calculating the curvature and normal vector with
+the level-set method in a reliable manner.  In this chapter, we consider
+a different problem of a more general nature:  How to solve partial
+differential equations (PDEs) in complex domains.  In particular, we consider
+an extension of a diffuse-domain method (DDM) by a high-order correction term
+that gives increased accuracy with respect to interface-width refinements.
+
+We begin with a short introduction to the diffuse-domain approach.  We then
+outline how it can be used to derive a DDM for the steady reaction-diffusion
+equation with Neumann boundary conditions.  Next, we continue with a brief
+introduction to the method of matched asymptotic expansions.  Finally, we
+introduce the high-order correction term derived in Paper~E and show that the
+resulting DDM converge with second order in the diffuse-interface width to the
+original problem.  The analysis also shows that the correction term is not
+necessary for second-order convergence.
+
+\section{Introduction}
+There exist several methods for solving PDEs in complex domains.  Most of them
+have in common that they require tools or methods that are not frequently
+available in standard finite-element or finite-difference software packages.
+Examples of such methods include the immersed-interface method
+\cite{LeVeque94}, the matched interface and boundary method \cite{Zhou06}, the
+extended and composite finite-element method \cite{Dolbow09}, embedded boundary
+methods \cite{Johansen98}, cut-cell methods \cite{Ji06}, and ghost-fluid
+methods \cite{Fedkiw99}.  A different approach, known as the fictitious domain
+method~\cite{Glowinski94,Glowinski96} or the domain imbedding
+method~\cite{Buzbee71}, either augments the original system with equations for
+Lagrange multipliers to enforce the boundary conditions, or use the penalty
+method to enforce the boundary conditions weakly.  For a more complete list of
+references, see Paper~E.
+
+The DDM is an alternative method for solving PDEs in complex domains.  The main
+idea is to use an implicit representation of the boundary, where the sharp
+boundary is replaced by a diffuse layer.  The PDEs are then reformulated on
+a larger, regular domain, and the boundary conditions are incorporated via
+source terms in the diffuse layer.  When the thickness of the diffuse layer is
+reduced, these source terms tend towards singular source terms.  The resulting
+PDEs can then be solved with the use of standard tools and methods.
+
+The diffuse-domain approach was first introduced by \citet{Kockelkoren03} to
+study diffusion inside a cell with homogeneous Neumann boundary conditions at
+the cell boundary.  It was later used by \citet{Li09} to develop a DDM for
+solving PDEs in complex evolving domains with Dirichlet, Neumann and Robin
+boundary conditions, which is hereafter called the DDM1.  The DDM1 has been
+used by \citet{Teigen09-b}, who modelled bulk-surface coupling of material
+quantities on a deformable interface.  It was also used by \citet{Aland10} to
+simulate incompressible two-phase flows in complex domains in 2D and 3D, and by
+\citet{Teigen11} to study two-phase flows with soluble surfactants.
+
+An analysis of the error behaviour of the diffuse-domain approach was done by
+\citet{Franz12} for a diffuse-domain approximation of an elliptic problem with
+Dirichlet boundary conditions.  They considered the infinity norm of the
+difference of the approximated solution and the exact solution, and their
+analysis shows that the approximation quality is of order one in the interface
+width.
+
+In Paper~E, we present the DDM2, which is an extension of the DDM1 by
+a high-order correction term.  The DDM2 is derived for elliptic problems with
+Neumann and Robin boundary conditions, and it is shown to be asymptotically
+second-order accurate in the interface width.  However, the analysis in Paper~E
+is somewhat lacking in that it assumes that the DDM1 is only first-order
+accurate.  In the following sections, we extend the analysis of Paper~E and
+show that the DDM1 is also second-order accurate.  The analysis is shown for
+the steady reaction-diffusion equation with Neumann boundary conditions, but
+the same technique also applies for the corresponding Robin problem.
+
+\section{The DDM for a Neumann problem}
+Consider the steady reaction-diffusion equation with Neumann boundary
+conditions,
+\begin{equation}
+  \begin{alignedat}{2}
+    \lapl u - u  &= f        & \txin D, \\
+    \ndot\grad u &= g \qquad & \txon \partial D,
+  \end{alignedat}
+  \label{eq:ddan}
+\end{equation}
+where $f$ and $g$ are given.  Let $\chi_D$ be the characteristic function of
+$D$,
+\begin{equation}
+  \chi_D = \begin{cases}
+    1 & \text{if $x\in D$,} \\
+    0 & \text{if $x\notin D$.}
+  \end{cases}
+\end{equation}
+The main idea with the diffuse-domain approach is to extend the original
+equation \eqref{eq:ddan} into a larger and regular domain $\Omega\supset D$, as
+depicted in \cref{fig:ddadomain}.  The extension can be written as
+\begin{equation}
+  \div(\chi_D\grad u) - \chi_D u + \text{BC} = \chi_D f,
+  \label{eq:ddm}
+\end{equation}
+where BC is a singular source term that represents the physical boundary
+condition on $\partial\Omega$.

+  \end{tikzpicture}
+  \caption{A regular domain $\Omega$ that contains a complex domain $D$.}
+  \label{fig:ddadomain}
+\end{figure}
+
+The characteristic function is typically approximated by the phase-field
+function,
+\begin{equation}
+  \chi_D \simeq \phi(\vct x,t) = \frac{1}{2} \left( 1
+  - \tanh \left( \frac{3r(\vct x,t)}{\epsilon} \right) \right),
+  \label{eq:characteristic}
+\end{equation}
+where $\epsilon$ is the interface width and $r(\vct x,t)$ is the
+signed-distance function with respect to the boundary $\partial D$, which is
+taken to be negative inside $D$.
+
+The main difficulty with the diffuse-domain approach is the derivation of
+approximations for the boundary condition term BC.  \citet{Li09} give four
+approximations that are shown to converge asymptotically with first order in
+$\epsilon$ to the original equation when $\epsilon$ is decreased.  In the
+following we consider the approximation
+\begin{equation}
+  \text{BC} \simeq |\grad\phi| g.
+  \label{eq:bc1}
+\end{equation}
+If we combine the above approximations \eqref{eq:characteristic} and
+\eqref{eq:bc1}, we get a DDM1 equation for \eqref{eq:ddan},
+\begin{equation}
+  \div\left(\phi\grad u\right) - \phi u +  |\grad\phi| g = \phi f.
+  \label{eq:ddm1}
+\end{equation}
+
+\section{The method of matched asymptotic expansions}
+The following is a brief introduction to the method of matched asymptotic
+expansions, which is used to show that a given diffuse-domain approximation
+converges to the original problem when the interface width is decreased.  More
+details can be found in Paper~E and in \cite{Pego88}.
+
+Let $u$ be some diffuse-domain variable.  The asymptotic convergence of a given
+diffuse-domain approximation can be shown through expansions of the
+diffuse-domain variables in powers of the interface thickness $\epsilon$ in
+regions close to and far from the interface.  For example, the expansions of
+$u$ are
+\begin{align}
+  u(\vct x)        &= \sum_{k=0}^\infty \epsilon^k      u^{(k)}(\vct x), \\
+  \hat u(z,\vct s) &= \sum_{k=0}^\infty \epsilon^k \hat u^{(k)}(z,\vct s),
+\end{align}
+where $u(\vct x)$ and $\hat u(\vct s,z)$ denote the outer and inner expansions,
+respectively.  Here $z$ is a stretched variable,
+\begin{equation}
+  z = \frac{r(\vct x)}{\epsilon},
+\end{equation}
+where $r$ is the signed distance from the point $\vct x$ to $\partial D$ and is
+taken to be negative inside $D$.  Further, $z$ and $\vct s$ form a local
+coordinate system such that
+\begin{equation}
+  \vct x(\vct s,z) = \vct X(\vct s) + \epsilon z\vct n(\vct s),
+\end{equation}
+where $\vct X(\vct s)$ is a parametrisation of the interface, $\vct n(\vct s)$
+is the interface normal vector, and $z$ is a stretched variable.
+
+When the inner and outer expansions are found, they are matched in a region
+where both solutions are valid and where $\epsilon z = \bigo 1$, see
+\cref{fig:regions}.  The outer solution is then evaluated in the inner
+coordinates, which leads to a set of matching conditions that must hold when
+$\epsilon\to 0$.  If we consider $\epsilon$ to be fixed and let $z \to
+\pm\infty$, we get the following asymptotic matching conditions:
+\begin{equation}
+  \label{eq:match1}
+  \zlimpm \hat u^{(0)}(z,\vct s) = u^{(0)}(\vct s),
+\end{equation}
+and as $z \to \pm\infty$,
+\begin{align}
+  \label{eq:match2}
+  \hat u^{(1)}(z,\vct s) &= u^{(1)}(\vct s)
+    + z\ndot\grad u^{(0)}(\vct s) + \smallo 1, \\
+  \begin{split}
+    \hat u^{(2)}(z,\vct s) &= u^{(2)}(\vct s)
+      + z\ndot\grad u^{(1)}(\vct s) \\
+      &\quad + \frac{z^2}{2} (\ndot\grad)\grad u^{(0)}(\vct s)\cdot\vct n
+      + \smallo 1.
+    \label{eq:match3}

+
+We remark that the inner expansion is used to obtain the boundary condition on
+$\partial D$, and that the outer solution is used to obtain the sharp-interface
+equation inside the physical domain $D$.
+
+To show that a given DDM approximation converges with second order, one must
+show that the order-one term of the outer solution of the DDM equation is zero
+in $D$.  As an example, we consider the outer solution of the DDM1 equation
+\eqref{eq:ddm1}, which is
+\begin{equation}
+  \begin{split}
+    \lapl u^{(0)} - u^{(0)} &= f, \\
+    \lapl u^{(1)} - u^{(1)} &= 0, \\
+    \lapl u^{(k)} - u^{(k)} &= 0,\qquad k = 2,3,\dots.
+  \end{split}
+  \label{eq:ddm_outer}
+\end{equation}
+For the solution to be asymptotically second order, that is $u = u^{(0)}
++ \bigo{\epsilon^2}$, we must have that $u^{(0)}$ satisfies the original
+problem \eqref{eq:ddan} and that $u^{(1)}=0$.  Thus the inner expansion must
+yield a boundary condition for $u^{(1)}$ to enforce $u^{(1)}=0$.
+
+\section{Asymptotic analysis of the DDM1 and the DDM2}
+\label{sec:DDM2}
+In Paper~E we present the DDM2, which extends the DDM1 \eqref{eq:ddm1} with
+a high-order correction term,
+\begin{equation}
+  \div\left(\phi\grad u\right) - \phi u +  |\grad\phi| g
+    + r|\grad\phi|\left(f - \kappa  g - \lapls u + u\right) = \phi f.
+  \label{eq:ddm2}
+\end{equation}
+Here $r|\grad\phi|\left(f - \kappa  g - \lapls u + u\right)$ is the
+correction term, $\kappa$ is the curvature of the boundary $\partial D$, and
+$\lapls u$ is the surface Laplacian of $u$, which can be defined as
+\begin{equation}
+  \lapls u \equiv
+  \left( I - \vct n\otimes\vct n \right)
+        \div \left( I - \vct n\otimes\vct n \right)\grad u,
+\end{equation}
+where $I$ is the identity matrix and $\vct n$ is the normal vector.  The
+curvature can be calculated from the phase-field function
+\eqref{eq:characteristic} as
+\begin{equation}
+  \kappa = -\div\frac{\grad\phi}{|\grad\phi|}.
+\end{equation}
+
+In the following, we use the method of matched asymptotic expansions to show
+that the DDM1 \eqref{eq:ddm1} and the DDM2 \eqref{eq:ddm2} are both
+second-order approximations of \eqref{eq:ddan} in $\epsilon$.  First, it is
+easy to see that the outer expansions of both approximations are given by
+\eqref{eq:ddm_outer}.
+
+Next, we consider the inner expansion of the DDM2 \eqref{eq:ddm2}, which is
+\begin{multline}
+  \frac{1}{\epsilon^2}\left(\phi\hat u_z\right)_z
+  + \frac \kappa \epsilon \phi\hat u_z
+  + \phi\lapls \hat u
+  - \phi\hat u \\
+  - \frac 1 \epsilon \phi_z g
+  - z\phi_z\left(\hat u + \hat f - \kappa g - \lapls\hat u\right)
+  = \phi \hat f.
+  \label{eq:ddm_inner}
+\end{multline}
+We expand $\hat u(z,\vct s)$ in powers of $\epsilon$ and collect the lowest
+order terms,
+\begin{equation}
+  \left(\phi\hat u_z^{(0)}\right)_z = 0.
+\end{equation}
+If we integrate over all $z$, we get that $\hat u_z^{(0)} = 0$.  The next order
+terms of~\eqref{eq:ddm_inner} then give
+\begin{equation}
+  \left(\phi\hat u_z^{(1)}\right)_z = \phi_z g,
+\end{equation}
+and again we integrate, which gives that
+\begin{equation}
+  \phi\hat u_z^{(1)} = \phi g + C
+  \label{eq:uz1}
+\end{equation}
+where the constant $C$ must be zero, since $\lim_{z\to\infty}\phi(z) = 0$.  Now
+consider the limit $z\to-\infty$ and use the matching condition
+\eqref{eq:match2} to get
+\begin{equation}
+  \ndot\grad u^{(0)} = g.
+\end{equation}
+Thus $u^{(0)}$ satisfies the original problem at least to first order in
+$\epsilon$.  This shows that both DDM1 and DDM2 are first-order approximations
+of the sharp-interface problem.
+
+To obtain the result for the next order, we need to apply the derivative of
+the matching condition \eqref{eq:match3},
+\begin{equation}
+  \hat u_z^{(2)} = \ndot\grad u^{(1)}
+      + z (\ndot\grad)\grad u^{(0)}\cdot\vct n.
+  \label{eq:match3_z}
+\end{equation}
+Further, we use that $u^{(0)}$ satisfies
+\begin{equation}
+  \lapl u^{(0)} - u^{(0)} = f^{(0)},
+\end{equation}
+and that the Laplacian may be decomposed as
+\begin{equation}
+  \lapl u = (\ndot\grad)\grad u\cdot\vct n + \kappa\ndot\grad u + \lapls u,
+\end{equation}
+to get
+\begin{equation}
+  (\ndot\grad)\grad u^{(0)}\cdot\vct n
+    = u^{(0)} + f^{(0)} - \kappa g - \lapls u^{(0)}.
+  \label{eq:ngradun}
+\end{equation}
+Now insert \eqref{eq:ngradun} into \eqref{eq:match3_z} and use the matching
+condition \eqref{eq:match1} to obtain a modified matching condition,
+\begin{equation}
+  \hat u_z^{(2)} - z\left(\hat u^{(0)} + \hat f^{(0)}
+        - \kappa g - \lapls \hat u^{(0)}\right)
+  = \ndot\grad u^{(1)}.
+  \label{eq:match3_z2}
+\end{equation}
+
+We are now ready to consider the zeroth order terms,
+\begin{multline}
+  \label{eq:o1}
+  \left(\phi\hat u^{(2)}_z\right)_z
+  + \phi\kappa\hat u_z^{(1)}
+  + \phi\lapls \hat u^{(0)}
+  - \phi\hat u^{(0)} \\
+  - z\phi_z\left(\hat u^{(0)}
+      + \hat f^{(0)} - \kappa g - \lapls\hat u^{(0)}\right)
+  = \phi \hat f^{(0)}.
+\end{multline}
+The modified matching condition \eqref{eq:match3_z2} motivates that we subtract
+and add the term
+\[
+  \bigg(z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\bigg)_z
+\]
+to \eqref{eq:o1}, which gives
+\begin{multline}
+  \bigg(\phi\hat u_z^{(2)}
+    - z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\bigg)_z \\
+  + \bigg(z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\bigg)_z \\
+  + \phi\kappa\hat u_z^{(1)}
+  + \phi\lapls \hat u^{(0)}
+  - \phi\hat u^{(0)} \\
+  - z\phi_z\left(\hat u^{(0)}
+      + \hat f^{(0)} - \kappa g - \lapls\hat u^{(0)}\right)
+  = \phi \hat f^{(0)}.
+\end{multline}
+We expand the terms and use \eqref{eq:uz1},
+\begin{multline}
+  \bigg(\phi\hat u_z^{(2)}
+    - z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\bigg)_z \\
+  + \cancel{\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)} \\
+  + z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)_z \\
+  + \cancel{\phi\kappa g
+  + \phi\lapls \hat u^{(0)}
+  - \phi\hat u^{(0)}}
+  = \cancel{\phi \hat f^{(0)}},
+  \label{eq:o2}
+\end{multline}
+or
+\begin{multline}
+  \bigg(\phi\hat u_z^{(2)}
+    - z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\bigg)_z \\
+  + z\phi\left(\cancel{\hat u_z^{(0)}} + \hat f_z^{(0)}
+      - \cancel{(\kappa g)_z}
+      - \cancel{\lapls \hat u_z^{(0)}}\right) = 0.
+\end{multline}
+If we assume that $\hat f_z^{(0)}$, we get
+\begin{equation}
+  \bigg(\phi\hat u_z^{(2)}
+    - z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\bigg)_z = 0.
+  \label{eq:o3}
+\end{equation}
+Finally, we integrate the left-hand side and take the limit,
+\begin{align}
+  \nonumber
+  \eint{\bigg(\phi\hat u_z^{(2)}
+    &- z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+     - \lapls \hat u^{(0)}\right)\bigg)_z} \\
+  \nonumber
+  &= \ejmp{\phi\hat u_z^{(2)}
+    - z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)} \\
+  \nonumber
+  &= -\zlimm{\left(\hat u_z^{(2)}
+    - z\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\right)} \\
+  &= -\ndot\grad u^{(1)},
+\end{align}
+thus
+\begin{equation}
+  \ndot\grad u^{(1)} = 0.
+  \label{eq:ngradu1}
+\end{equation}
+Combined with \eqref{eq:ddm_outer}, this shows that $u^{(1)}=0$, and so DDM2
+converges asymptotically with second order to the original problem.
+
+The analysis above also holds for DDM1, except instead of \eqref{eq:o3} we get
+\begin{multline}
+  \bigg(\phi\hat u_z^{(2)}
+    - z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\bigg)_z \\
+  = - z\phi_z \left(\hat u^{(0)} + \hat
+        f^{(0)} - \kappa g - \lapls \hat u^{(0)}\right)
+  = - z\phi_z D,
+  \label{eq:o4}
+\end{multline}
+where $D$ is independent of $z$.  Now we use that
+\begin{equation}
+  \phi_z = -(3 \sech^2 3z)/2,
+\end{equation}
+which follows from the definition of the phase-field function
+\eqref{eq:characteristic}.  We integrate the right-hand side, which gives
+\begin{equation}
+  D\eint{z\phi_z} = -D\frac 3 2\eint{z\sech^2 3z} = 0.
+\end{equation}
+Thus DDM1 is also second order in $\epsilon$.
+
+The difference between the DDM1 and the DDM2 is therefore that the correction
+term with the DDM2 directly cancels the term on the right-hand side in
+\eqref{eq:o4}.  This should give an increase of accuracy, but the convergence
+order remains the same.
+
+The analysis for the corresponding Robin problem is essentially the same as the
+above.  In Paper~E, the DDM1 and DDM2 are compared for several elliptic
+problems with both Neumann and Robin boundary conditions.  The results of
+Paper~E show that the correction term in the DDM2 leads to an increase of
+accuracy and that both DDM1 and DDM2 converge with second-order accuracy.
+
+\section{Summary}
+In this chapter, we have given a brief introduction to the diffuse-domain
+method (DDM).  We considered a steady reaction-diffusion equation with Neumann
+boundary conditions \eqref{eq:ddan} and two DDM approximations:  DDM1
+\eqref{eq:ddm1} and DDM2 \eqref{eq:ddm2}.  The DDM2 is an extension of DDM1 by
+a high-order correction term, and was first derived in Paper~E.
+
+Next, we gave an outline of the method of matched asymptotic expansions, and we
+used it to show that both the DDM1 and the DDM2 converged asymptotically with
+second order in the diffuse-interface width to the original equation
+\eqref{eq:ddan}.  The analysis shows that the correction term in the DDM2 leads
+to a cancellation in the asymptotic expansions.  By doing the integration, we
+see that this cancellation is not necessary for obtaining the second order
+convergence.

+\section[Paper A]{Paper A:  Calculation of interface curvature with the
+  level-set method}
+Karl Yngve Lervåg.  Published in \emph{MekIT'11 - 6th National Conference on
+  Computational Mechanics, Trondheim}, 2011.  ISBN: 978-82-519-2798-7.
+
+In this paper I address a problem with the calculation of the interface
+curvature with the level-set method, cf.\ \cref{sec:curvature}.  The curvature
+can be calculated from the level-set function, $\phi$, as
+\begin{equation}
+  \kappa = \div\vct n = \div\frac{\grad\phi}{|\grad\phi|}.
+\end{equation}
+It is typically discretized by standard methods such as the second-order
+central-difference scheme (CD-2), and interpolated to the interface where
+needed \cite{Osher88,Kang00,Osher03}.  However, the level-set function as
+a signed-distance function will tend to have kinks where its gradient is
+discontinuous.  The standard methods may lead to large errors in the curvature
+close to these regions, which in turn may lead to errors in the surface tension
+force.
+
+The main contribution of this paper is a new curve-fitting discretization
+method (CFDM) for the curvature (see \cref{sec:curvature-curve-fitting}).  The
+method is based on the approach developed by \citet{Macklin06}.  It differs in
+that it uses a cubic Hermite spline parametrisation of the interface, and that
+the curvature values are calculated on the grid and then interpolated to the
+interface as opposed to using a localised grid centred at the interface as in
+\cite{Macklin06}.

+\end{figure}
+
+The CFDM is tested and compared with the CD-2 for two test cases, and it is
+shown to yield better results in both cases.  \Cref{fig:A1} shows one of these
+results, where the calculated curvature values are compared.  In the example,
+a cylindrical drop impacts on a liquid film.  The figure shows that the CD-2
+leads to large errors in the curvature calculations in the kink regions, that
+is, the red and dark blue regions in \cref{fig:A1a} near the liquid film.
+These errors are not present with the new method, cf.\ \cref{fig:A1b}.
+

+\section[Paper B]{Paper B:  Curvature calculations for the level-set method}
+Karl Yngve Lervåg and Åsmund Ervik.  Published in \emph{ENUMATH 2011}
+proceedings volume, Springer, 2013.  ISBN: 978-3642331336.
+
+This paper is a continuation of Paper A.  The main contribution in this paper
+is a comparison of different methods for calculating the curvature in a robust
+manner with the level-set method in the kink regions.  In particular, the
+CFDM\footnote{The method is called LM in the paper.  Here CFDM is used, in
+  order to be consistent with the rest of the thesis.} that was presented in
+Paper A is compared with Macklin and Lowengrub's method (MLM)~\cite{Macklin06}.
+In addition, the method is compared with the second-order central-difference
+scheme (CD-2) and the more recent method presented by \citet{Salac08}, here
+called Salac and Lu's method (SLM).
+
+The main result in the paper is shown in \cref{fig:B1}, which shows
+a comparison of the methods for a case where two drops collide in a 2D shear
+flow.  In particular, it shows snapshots of the evolution of the interfaces and
+the curvature at times $t=\SI{2.30}{s}$, $t=\SI{2.75}{s}$, and
+$t=\SI{3.10}{s}$.  The results show that all of the improved methods, that is
+MLM, CFDM, and SLM, handle the kink region in a more reliable manner than CD-2.
+The reason that the result with MLM differs from those with CFDM and SLM might
+be that it uses a localised grid centred at the interface to calculate the
+curvature, which means that it does not need to use interpolation of the
+curvature from the grid to the interface.  Note that the difference is mainly
+that the MLM results in slightly earlier coalescence in the given case.

+\section[Paper C]{Paper C:  Calculation of the interface curvature and normal
+  vector with the level-set method}
+Karl Yngve Lervåg, Bernhard Müller, and Svend Tollak Munkejord.  Published in
+Computers and Fluids, volume 84 (2013), 218--230.
+
+Paper A presented the curve-fitting discretization method (CFDM) for the
+calculation of the curvature with the level-set method.  The method was
+designed to be robust in the calculation of the curvature in kink regions, that
+is regions where the gradient of the level-set function is not smooth.  This
+paper presents the details of the CFDM and applies it to the calculation of
+both the curvature and the normal vector.
+
+In the paper we compare the CFDM with the second-order central-difference
+scheme (CD-2) for several test cases.  In the first case, we consider the
+curvature calculations for a nontrivial geometry that includes some kink
+regions.  This is a static test case with no flow, and the results show that
+the CD-2 leads to large errors for the curvature calculations in areas close to
+kink regions and that these errors are not present with the CFDM.
+
+In the following two cases, we consider the collision of two drops in a 2D
+shear flow and in an axisymmetric flow.  These cases show that the errors in
+the curvature calculations in the kink regions with the CD-2 lead to errors in
+the pressure that prevents coalescence.  These errors are prevented with the
+CFDM.  The curvature and the evolution of the interfaces for the axisymmetric
+case are shown in \cref{fig:C1,fig:C2}.  As in the earlier results of Papers
+A and B, the figures show that the errors in the curvature calculation with
+CD-2 prevent coalescence, in this case leading to a slower coalescence process.

+\section[Paper D]{Paper D:  A robust method for calculating interface curvature
+  and normal vectors using an extracted local level set}
+Åsmund Ervik, Karl Yngve Lervåg, and Svend Tollak Munkejord.  Submitted to
+Journal of Computational Physics, 2013.
+
+In this paper we present an alternative method for the calculation of the
+curvature and the normal vector of an interface with the level-set method in
+kink regions, hereafter called the local level-set extraction (LOLEX) method.
+The method is based on a method presented by \citet{Salac08} (SLM), who handle
+the kink region by extracting different bodies of a domain into separate
+level-set functions.  This procedure removes most of the kink regions, but it
+does not handle kink regions that are due to complex interfaces of single
+bodies.  Our method extends the SLM by making it local.  That is, we only
+consider the local area around the point for which we are calculating the
+curvature or the normal vector.  This leads to a method that is more generally
+applicable, as shown in \cref{fig:D1}.  The figure shows a comparison between
+the LOLEX method, the SLM, and the standard central differences (CD-2).  CD-2
+leads to curvature spikes at the kink regions, as explained in
+\cref{sec:curvature}.  The SLM gives a better result for the kink regions
+around the rightmost disc.  However, since the other two discs are connected to
+each other and to the film, they are considered to be the same body and are
+extracted into the same level-set function.  Several kink regions are therefore
+not removed.  Since the LOLEX method only considers the local area, as
+explained in \cref{sec:lolex}, it is able to handle all the kink regions in
+a robust manner.

+    negative and red is positive.}
+  \label{fig:D1}
+\end{figure}
+
+The LOLEX method has proven to be a good alternative to the CFDM presented in
+Paper A.  Its main advantages are that it does not rely on complex algorithms
+as used in the CFDM or by \citet{Macklin06}, and that the method easily extends
+to 3D as demonstrated in the paper in Section~4.4.
+
+In the previous papers A--C, we used the DP1 projection method by
+\citet{Hansen05}.  In this paper we instead used the more standard Chorin
+projection method.  These methods differ in that the DP1 assumes
+\begin{equation}
+  \div\left(\pdt{\vct u}\right) = 0.
+\end{equation}
+When compared with the Chorin method, this assumption becomes equivalent to
+assuming that $\div\vct u^{n} = 0$ in \eqref{eq:PoissonChorin}.  That is, the
+DP1 assumes that the initial velocity field is divergence free.  We have found
+that the DP1 works well in most cases, but that it is less robust than the
+Chorin method.  In particular, the Chorin method is not equally affected by
+errors in the curvature calculations in kink regions.  In other words, the
+difference between using a standard discretization and an improved
+discretization of the curvature is smaller with the Chorin method than with the
+DP1.
+
+The LOLEX method is used for several test cases and compared with CD-2.  The
+results indicate that even though we use the Chorin projection method, the
+LOLEX method outperforms CD-2 in all cases.  Further, the results agree well
+with experiments, except for time instants, as shown in \cref{fig:D2}.  The
+exact reason why the time instants do not match is not known, but one reason
+may be that the initial condition of the numerical simulation did not match the
+corresponding state of the experiment.

+    from~\cite{Zhao11}, Copyright (2011), with permission from Elsevier.}
+  \label{fig:D2}
+\end{figure}
+
+When we study the drop-film collision processes, an important consequence of
+the error in the curvature calculation is a loss of kinetic energy.  This can
+be seen in \cref{fig:D3}, which compares the LOLEX method with CD-2 at two
+different stages of the collision process.  The figure also compares two
+different frequencies of reinitialization of the level-set function:  Every
+7 time steps ((a) and (c)) and every single time step ((b) and (d)).  The
+figure shows that the error in the curvature calculation with CD-2 leads to
+a shorter neck, as seen in \cref{fig:D3}, (c) and (d).  The error is larger for
+the higher frequency of reinitialization.  The results indicate that CD-2 leads
+to a loss of kinetic energy during the collision process when compared with the
+LOLEX method.  The LOLEX method is not significantly affected by the amount of
+reinitialization, and the kink region does not affect the curvature
+calculation, cf.\ \cref{sec:lolex}.  Thus the pressure field is more sensible,
+as seen in \cref{fig:D3} (a) and (b).  Finally, we remark that some authors
+have noted \cite{Blanchette06} that the height of the neck and the dynamics of
+the capillary waves are important factors for the partial coalescence
+mechanism, which implies that the correct calculation of the curvature is
+important to capture the correct physical behavior.

+\section[Paper E]{Paper E:  Towards a second-order diffuse-domain approach for
+  solving PDEs in complex geometries}
+Karl Yngve Lervåg and John Lowengrub.  Submitted to Communications in Math.
+Sciences, 2013.
+
+\citet{Li09} developed a diffuse-domain method for solving partial-differential
+equations (PDEs) inside complex, dynamic geometries with Dirichlet, Neumann,
+and Robin boundary conditions.  This method is in the following referred to as
+DDM1.  They use the diffuse-domain approach~\cite{Kockelkoren03}, where the
+geometry is represented implicitly and the sharp boundary is replaced by
+a diffuse layer with a fixed interface width.  The original governing equations
+are then reformulated on a larger, regular domain and the boundary conditions
+are incorporated via singular source terms.  The method of matched asymptotic
+expansions is used to show that the reformulated problem converges
+asymptotically to the original problem.
+
+In the present paper, we use the method of matched asymptotic expansions to
+extend the DDM1 with include a high-order correction term in the diffuse
+formulation, cf.\ \cref{sec:DDM2}.  The extension is derived for elliptic
+problems with Neumann and Robin boundary conditions, where the correction term
+is shown to yield an asymptotically second-order accurate approximation of the
+original problem.  The new method is referred to as the DDM2.
+
+The DDM1 and DDM2 are compared for a selection of test problems.  The resulting
+equations were discretized by standard second-order central-difference schemes
+on uniform grids, and solved by a multigrid method.  A red-black Gauss-Seidel
+type iterative method was used as a smoother, see \cite{Wise07}.
+
+In addition to the comparison of DDM1 and DDM2, we compared two different
+approximations of the boundary conditions.  These correspond to different
+diffuse-interface surface delta functions, and for the Neumann boundary
+conditions they are
+\begin{equation}
+  \text{BC1} = |\grad\phi| g,
+\end{equation}
+and
+\begin{equation}
+  \text{BC2} = \epsilon|\grad\phi|^2 g.
+\end{equation}
+The approximations are similar for the Robin boundary condition, although here
+it was found that only BC1 resulted in a valid asymptotically second-order
+accurate DDM2.
+
+Our results show that the global accuracy and convergence of DDM2 is better
+than DDM1, however both methods perform well and the global convergence rate is
+around two for each.  The error was measured as the L$_2$ norm of the
+difference between an analytic solution and the solution $u_\epsilon$ for
+a given interface width, $\epsilon$.
+
+\Cref{fig:E1,fig:E2} show two of the results, the first one with the Neumann
+boundary conditions and the second with the Robin boundary condition.  The
+results indicate that DDM2 performs slightly better than DDM1.  They also show
+that the approximation BC1 gives more accurate results than BC2.  In
+particular, we found that with BC2 we needed much finer grids to obtain
+convergence for a given $\epsilon$.  For the smallest values of $\epsilon$ we
+were not able to refine the grids enough to obtain valid results.

+\chapter{Conclusions and outlook}
+\label{chap:conclusions}
+This thesis has considered two different problems:  The discretization of
+interface curvature and normal vectors with the level-set method and
+a diffuse-domain approach for solving partial-differential equations (PDEs) in
+complex domains.  In the following, some general concluding remarks and
+recommendations for further work are given.
+
+\section*{Conclusions}
+The first part of the thesis considered the modelling of incompressible
+two-phase flow.  The main motivation was to study two-phase flow phenomena that
+are relevant for compact heat exchangers, such as drop-drop and drop-film
+collisions.  In particular, the thesis addressed a challenge with the
+calculation of interface curvature and normal vectors with the level-set
+method.  Two methods were presented to handle the discretization in the kink
+regions: A curve-fitting discretization method (CFDM) and a local level-set
+extraction (LOLEX) method.  Both methods were shown to be robust in the kink
+regions, where the standard central-difference scheme (CD-2) fails.  Of these
+methods, the LOLEX method is the preferred method, because it relies on a less
+complicated algorithm that easily extends to 3D.
+
+CD-2 and the LOLEX method were used for simulations of drop-film collisions
+that were compared with experiments.  The results showed that CD-2 leads to
+errors in the curvature that cause unphysical pressure spikes during the
+coalescence.  The errors are shown to lead to a dissipation of kinetic energy
+during the collision and to a slower coalescence process.  The LOLEX method was
+shown to prevent these unphysical pressure spikes, and to produce to more
+accurate results.
+
+The second part of the thesis considered the diffuse-domain approach for
+solving PDEs in complex domains.  The main contribution, presented in Paper~E,
+was the derivation of an asymptotically second-order diffuse-domain method
+(DDM2) for solving elliptic problems in complex geometries with Neumann and
+Robin boundary conditions.  The new method is an extension by a high-order
+correction term of the method presented in \cite{Li09}, here called DDM1.  The
+DDM1 and DDM2 were compared, and the results indicated that the DDM2 was
+slightly better than the DDM1.
+
+The thesis has expanded on the results of Paper~E with a new asymptotic
+analysis that shows that DDM1 is in fact also asymptotically second order.
+This analysis helps to explain why the performance of DDM2 presented in Paper~E
+is only slightly better than that of DDM1.  As such, the new analysis leads to
+a better understanding of the DDM1 and the DDM2.
+
+\section*{Outlook}
+The following gives an outline of some possibilities for future work.
+\begin{itemize}
+  \item A natural continuation of this work is to perform more in-depth
+    comparisons of simulations with experiments for the drop-film collision
+    phenomenon that was started in Paper~D.  In addition, it would be
+    interesting to study other two-phase flow phenomena that are relevant for
+    heat-exchanger processes, for instance drop-drop collisions or flow across
+    tube bundles.  The latter requires the treatment of more complex boundaries,
+    which can be handled either with the diffuse-domain method or other methods
+    from the literature.
+  \item Paper~C gave a short comparison of the standard discretization method
+    (CD-2), the direction-difference scheme (DDS), and the curve-fitting
+    discretization scheme (CFDM) applied to the calculation of the normal
+    vectors.  The results showed that the CD-2 leads to inaccurate results in
+    the kink regions.  The DDS gives robust and accurate results in most cases,
+    but an example is given where only the CFDM yields an accurate result.
+    However, the impact of inaccurate calculations of the normal vector should
+    be investigated in more detail.  The normal vector is used both for the
+    solution of the level-set equations \eqref{eq:ls_adeq},
+    \eqref{eq:ls_velextr}, and \eqref{eq:ls_reinit}, and for the calculation of
+    the interface jumps \eqref{eq:jump_pressure} and \eqref{eq:jumptens}, so
+    one can expect that large errors in the calculation of the normal vector
+    may lead to large errors in the numerical solution.  This warrants
+    a further study.
+  \item Mass and heat transfer are obviously an important part of the
+    heat-exchanger processes.  The models that have been used in this thesis
+    should therefore be expanded with additional models for heat transfer and
+    mass transfer to enable the simulation of more relevant phenomena.
+  \item The DDM2 was only derived for problems with Robin and Neumann boundary
+    conditions.  If possible, it should be extended to also work with Dirichlet
+    boundary conditions.
+  \item As explained in Paper~E, we found that we were unable to solve the
+    discrete system of equations when the surface Laplacian part of the
+    correction term for the DDM2 was included.  A further investigation of this
+    problem should be done, and stable numerical methods to solve the full DDM2
+    equations should be developed.
+  \item The diffuse-domain approach is a promising method for solving problems
+    in complex and confined geometries with standard tools and methods.
+    \citet{Aland10} provide a diffuse-domain formulation of the Navier-Stokes
+    Cahn-Hilliard equations for incompressible two-phase flow and use it to
+    compute two-phase flow in both complex and confined geometries.  However,
+    they do not provide an asymptotic analysis of the reformulated equations to
+    show that the system converges.  Such an analysis would be interesting, in
+    particular to verify that the equations do converge to the original problem
+    when the interface width is decreased.
+  \item Finally, it would be interesting to develop a second-order
+    diffuse-domain formulation for the incompressible Navier-Stokes equations.
+    A starting point would be to use the results and techniques from this
+    thesis and Paper~E.

+\chapter{Introduction}
+This thesis considers the mathematical modelling and numerical computation of
+two-phase flows.  It focuses on developing more robust numerical methods to
+calculate the curvature and the normal vector of the interface between the two
+phases.  In addition it considers a diffuse-domain method for solving partial
+differential equations in complex geometries, and it derives an asymptotically
+second-order method for elliptic problems.
+
+\section{Background and motivation}
+Two-phase flows are particular examples of multiphase flows of gas and liquid
+with an interface that separates the two phases.  In the pedantic sense,
+two-phase flow is flow of a single fluid that occurs as two different phases,
+for example steam and water.  However, it is common to be more general, and in
+this thesis we use the term two-phase flow also for immiscible mixtures of
+different fluids, such as water and oil.
+
+Two-phase flows are crucial to a large amount of processes, both in nature and
+in industry.  Examples range from weather phenomena, such as rain drops falling
+through air, to industrial processes, for instance the separation of water from
+oil.  In general, multiphase flow phenomena influence any process where liquids
+and gases are involved.  In the oil and gas industry, most processes are
+two-phase or multiphase flow processes.  Needless to say, the understanding of
+these phenomena is fundamental in the development of new or improved processes.
+
+Consider the international trade of liquefied natural gas (LNG), which is
+a particular branch of the oil and gas industry that has undergone an
+exceptional growth in the last decades.  There is a strong focus both in Norway
+and internationally on producing LNG on large floaters
+(FLNG)\footnote{FLNG facilities do not yet exist, although a facility is under
+  development by Royal Dutch Shell~\cite{Prelude1}.  The construction of this
+  facility was started in 2012, and the first drilling is stated to commence in
+  2013~\cite{Prelude2}.}.  There are a number of both environmental and
+economic advantages of such FLNG facilities.  In particular, FLNG facilities
+would remove the need of long pipelines from the gas fields to the shore, there
+would be no requirement for compression units to pump the gas to the shore, and
+one would not need to construct onshore production facilities.  This would
+significantly reduce the environmental footprint, and would help preserve
+marine and coastal environments.  Since an FLNG facility can be moved to a new
+location when a field has been depleted, it would make it economically viable
+to open up new business opportunities to develop offshore gas fields that would
+otherwise remain stranded.
+
+Moving the LNG production to an offshore facility presents a demanding set of
+challenges.  A particular challenge is that the elements of a conventional LNG
+facility need to fit into an area roughly one quarter the original size.  Heat
+exchangers are among the main challenges in the design and operation of LNG
+plants \cite{Hesselgreaves01}.  Compact and efficient heat exchangers are
+needed to obtain an energy efficient plant with low emissions.  More optimized
+designs require more accurate tools for design and operation.  Such tools can
+only come as a result of an improved physical understanding of the complex
+two-phase flows occurring in the heat exchangers.  This can be achieved by more
+detailed mathematical modelling, together with dedicated laboratory
+observations, cf.\ \cite{Olsen07}.
+
+\section{Overview of methods for two-phase flow simulations}
+In the following, a brief overview is given of different methods for modelling
+two-phase flows where the interface location is known.  In particular, we focus
+on methods that handle the interface evolution.  For more in-depth reviews, see
+for instance \cite{Cristini04,Scardovelli99,Sethian03}.
+
+Interface propagation methods comprise a range of methods that are often
+categorised as either front tracking or front capturing.  Front-tracking
+methods use Lagrangian particles to track the interface
+explicitly~\cite{Tryggvason01}, while front-capturing methods use an Eulerian
+approach to capture the interface implicitly.  Examples of the latter are
+volume-of-fluid methods~\cite{Scardovelli99,Tryggvason11}, phase-field
+methods~\cite{Anderson98,Jacqmin99,Lowengrub98}, and level-set
+methods~\cite{Osher03}.
+
+The main advantages of front-tracking methods are their inherent accuracy and
+that topological changes do not occur without explicit action.  Hence,
+unphysical numerical reconnection does not occur.  This means that if front
+tracking is used for the simulations of two drops that collide, these drops
+will not coalesce due to numerical reconnection or merging.  However, the
+handling of topological changes are challenging, in particular in three
+dimensions~\cite{Shin02}.  Also, there are some issues of numerical
+instabilities, as discussed by \citet{Sethian85} and \citet{Osher88}.
+
+The volume-of-fluid method utilizes a volume-fraction function whose values
+represent the characteristic function of one of the fluid domains.  Its values
+are zero or one, except in those cells cut by the interface.  A considerable
+advantage of the volume-of-fluid method is that it conserves the mass of both
+fluids well.  However, the reconstruction of the interface from volume
+fractions is not simple, and computation of geometric quantities such as the
+interface curvature is not straightforward.  Also, spurious bubbles and drops
+may be created, cf.\ \cite{Lafaurie94}.
+
+The phase-field methods treat the interface in a diffuse manner, where the
+fluid properties, such as density and viscosity, change rapidly but smoothly
+across the interface.  These methods typically solve the coupled
+Cahn-Hilliard/Navier-Stokes equations, where the Cahn-Hilliard equation is
+based on the free energy of an interface~\cite{Cahn57}.  Through this energy
+formulation, one can model more advanced interface physics such as van der
+Waals interactions, electrostatic forces, and fluids with varying
+miscibilities.  However, the phase-field methods require that one resolves very
+small length scales at the interfaces.  This poses a severe restriction on the
+applicability of phase-field methods for two-phase flow, where the length
+scales of the flow are generally much larger than those of the interface.
+
+In this thesis, we have used the level-set method~\cite{Osher88}, which
+implicitly captures the interface as an isocontour of a function defined in the
+entire domain.  The main motivation of this choice is both that the level-set
+method handles topological changes of evolving interfaces automatically,
+cf.~\citet{Sethian03}, and that it is relatively straightforward to implement.
+
+It should be noted that the automatic handling of topological changes is not
+based on physical principles.  For instance, when two interfaces approach each
+other and their distance becomes less than the spacing of the grid, the
+level-set method can no longer resolve both interfaces and so they are merged.
+An important consequence is that the level-set method does not model the
+physics involved in the coalescence process, and in particular in the smaller
+scales of the film-drainage process.  This process involves a wide range of
+length scales, varying from the nanometer scale where van der Waals force are
+active to the length scales of the external flow.  Some effort has been made to
+include the effects of the smaller scales in front-capturing methods,
+cf.~\cite{Nobari96,Tryggvason10}.  Recently, \citet{Kwakkel13} presented
+a level-set/volume-of-fluid method that is coupled with a film-drainage model
+that predicts if and when two colliding droplets will coalesce.  To prevent the
+numerical coalescence, each droplet has its own locally defined level-set
+function.
+
+The level-set method has been used to model several diverse phenomena,
+such as tumour growth~\cite{Macklin06,Macklin05,Macklin08}, propagation of
+wildland fire~\cite{Mallet09}, and computer RAM production~\cite{Melicher08}.
+For a good and thorough introduction to the level-set method, see
+\cite{Osher03}.
+
+A weakness of the level-set method is that it does not conserve the mass of the
+two fluids, in particular in areas of low resolution and/or high curvature.
+Different approaches have been developed to overcome this disadvantage, for
+example the conservative level-set method~\cite{Olsson05,Olsson07}, the
+particle level-set method~\cite{Enright02}, or the coupled
+level-set/volume-of-fluid method~\cite{Sussman00}.
+
+When we use the level-set method to capture the interface for immiscible and
+incompressible two-phase flow simulations, there will be a sharp change in the
+density and viscosity across the interface.  In this thesis we use the
+ghost-fluid method~\cite{Fedkiw99}, which is a sharp-interface method where the
+jumps are included in the spatial discretizations in a sharp manner.  An
+alternative method is the continuous surface-force method introduced by
+\citet{Brackbill92}, where the density and the viscosity are smeared out across
+the interface through a smoothed Heaviside function.
+

+\section{Goal and contribution of the present thesis}
+The main goal of the PhD project has been to develop fundamental knowledge of
+two-phase flow phenomenon that are relevant for compact heat exchangers.
+
+In order to do detailed theoretical studies of phenomena that are relevant for
+compact heat exchangers, we need to consider two-phase flows with mass and heat
+transfer in confined and complex geometries.  One such relevant phenomenon is
+the drop-film collision process \cite{Zhao09}.  Even when restricted to
+isothermal and immiscible flows, this simple phenomenon remains a challenge.
+When the level-set method is used to capture the interface, one must be
+particularly careful about how one calculates the interface curvature and
+normal vector.  For instance, when two drops are in near collision there is
+a kink region in the level-set function between the drops, where the gradient
+is discontinuous, see \cref{fig:curvature-problem}.  This discontinuity may
+lead to large errors in the curvature and the normal vector if it is not taken
+into account in the discretization stencils.

+
+As a step towards computing two-phase flow simulations in confined geometries,
+the thesis has considered the diffuse-domain method~\cite{Li09}.  This is
+a method where partial-differential equations in complex domains are extended
+into larger, regular domains with the use of diffuse approximations of the
+physical boundaries.  The approximations converge asymptotically to the
+original problem when the width of the diffuse boundary is reduced.  With this
+method one can use standard numerical methods to solve equations that
+incorporate complex boundaries.
+
+The main contributions of the present thesis are two new methods to calculate
+the curvature and normal vector in a robust manner with the level-set method.
+These methods are shown to yield more accurate calculations of drop-film and
+drop-drop collisions.  The methods are compared with standard methods and with
+other methods from the literature.
+
+In addition, the thesis presents an extension of a diffuse-domain method by
+a high-order correction term for the solution of elliptic problems in complex
+geometries.  New analysis provided in the thesis improves the understanding of
+the diffuse-domain method, and the derived method is shown to be more accurate
+than the existing diffuse-domain method.
+
+\section{Outline of the thesis}
+The thesis is organised as follows: \Cref{chap:two-phase-flow} gives a brief
+overview of the derivation of the governing equations for two-phase flow.  It
+includes a consideration of the fluid-fluid interface conditions and the
+derivation of a simplified jump tensor for the viscous term at the interface.
+
+\Cref{chap:numerical-methods} gives a detailed description of the numerical
+methods that are used to solve the two-phase flow equations.  In particular, it
+describes the level-set method, which is used to capture the interfaces,
+projection methods that are used to solve the Navier-Stokes equations, and the
+spatial and temporal discretization schemes.  At the end of the chapter, an
+overview of the novel discretization methods for the curvature and the normal
+vector is given.
+
+\Cref{chap:diffuse-domain} gives a short introduction to the diffuse-domain
+method for an elliptic problem with Neumann boundary conditions.  It introduces
+the high-order correction term, and shows that the new method converges
+asymptotically with second-order to the original problem.  The chapter presents
+new analysis that shows that the correction term is not necessary for
+second-order convergence.
+
+In \cref{chap:contributions} the main results of the contributed papers A--E
+are summarized, and the author's contributions are highlighted.  Finally,
+\cref{chap:conclusions} gives concluding remarks and provides an outlook for
+future work.

+\chapter{Governing equations for two-phase flow}
+\label{chap:two-phase-flow}
+In this chapter we will give a brief overview of the derivation of the
+governing equations for two-phase flow.  We begin with a consideration of the
+Navier-Stokes equations for single-phase flow.  We then introduce a singular
+surface-force term and derive the Navier-Stokes equations for two-phase flow.
+Finally, we use the Navier-Stokes equations for two-phase flow to derive jump
+conditions at the interface between the phases.
+
+\section{The Navier-Stokes equations for single-phase flow}
+The following is a brief derivation of the Navier-Stokes equations for
+single-phase flows.  For a more thorough derivation of these equations, see for
+instance \citet[§4 and §5]{Aris89} or \citet[Chapter~4]{White03}.
+
+We consider a single-phase, viscous flow in some domain $\Omega$ with boundary
+$\partial\Omega$.  When temperature effects are neglected the flow is described
+by the Cauchy equation
+\begin{equation}
+  \label{eq:cauchy_equation}
+  \rho\left(\cd{\vct u}\right) = \div\tenstr+\rho\vct f,
+\end{equation}
+and the mass conservation equation,
+\begin{equation}
+  \label{eq:cons_of_mass}
+  \pdt\rho + \div(\rho\vct u) = 0.
+\end{equation}
+Here $\rho$ is the fluid density, $\vct u$ is the flow velocity, $t$ is time,
+$\tenstr$ is the stress tensor, $\vct f$ denotes body forces, and $\del$ is
+used to denote the gradient and divergence operators.  The stress tensor for
+Newtonian fluids with zero bulk viscosity is
+\begin{equation}
+  \tenstr = -p\tenI + 2\mu\tenD - \frac 2 3\mu (\trace\tenD) \tenI,
+  \label{eq:viscous_stress_tensor}
+\end{equation}
+where $p$ is the pressure, $\tenI$ is the identity tensor, $\mu$ is the dynamic
+viscosity, and $\trace\tenD$ denotes the trace of the strain-rate tensor
+$\tenD$,
+\begin{equation}
+  \tenD = \frac{1}{2}\left( \grad\vct u + (\grad\vct u)^T \right).
+  \label{eq:deformation_tensor}
+\end{equation}
+For incompressible flow, the mass-conservation equation reduces to
+\begin{equation}
+  \label{eq:navier-stokes-1}
+  \div\vct u = 0,
+\end{equation}
+that is, the velocity field must be divergence free.  If we further assume that
+the viscosity is constant, then it follows that the divergence of the stress
+tensor reduces to
+\begin{equation}
+  \label{eq:stress_tensor}
+  \div\tenstr = -\grad p + \mu\lapl\vct u,
+\end{equation}
+and so the Cauchy equation \eqref{eq:cauchy_equation} becomes
+\begin{equation}
+  \rho\left(\cd{\vct u}\right) = -\grad p + \mu\lapl\vct u + \rho\vct f.
+  \label{eq:navier-stokes-2}
+\end{equation}
+Equations \eqref{eq:navier-stokes-1} and \eqref{eq:navier-stokes-2} are the
+incompressible Navier-Stokes equations for single-phase flow with constant
+viscosity.
+
+\section{The Navier-Stokes equations for two-phase flow}
+We now consider an immiscible two-phase flow of two Newtonian fluids, each with
+its own viscosity and density.  We let $\Omega_1$ and $\Omega_2$ denote the
+domains occupied by fluid 1 and fluid 2, respectively, and let the interface
+between the fluids be denoted by $\Gamma$.  Then $\Omega
+= \Omega_1\cup\Omega_2$ and $\partial\Omega
+= (\partial\Omega_1\cup\partial\Omega_2)\setminus\Gamma$ are the fluid domain
+and its boundary, respectively.  See \cref{fig:domain} for an illustration of
+a two-phase flow domain.

+    separates the two phases $\Omega_1$ and $\Omega_2$.}
+  \label{fig:domain}
+\end{figure}
+
+The extension of the single-phase model to account for two fluids can be made
+by adding a singular surface-force term to represent the effects of surface
+tension between the fluids.  We assume that the surface tension is constant, in
+which case the singular surface force can be defined as
+\begin{equation}
+  \funssf(\vct x,t)
+  = \int_{\Gamma}\sigma\kappa\vct n\delta(\vct x - \vct x_I(\vct s))\dif\vct s,
+  \label{eq:ssf}
+\end{equation}
+where $\sigma$ is the surface tension, $\kappa$ is the local curvature, $\vct
+n$ is the normal vector, $\delta$ is the Dirac delta function, and $\vct
+x_I(\vct s)$ is a parametrisation of the interface.  Thus the Navier-Stokes
+equations for immiscible and incompressible two-phase flow are
+\begin{align}
+  \label{eq:ns1}
+  \div\vct u &= 0, \\
+  \label{eq:ns2}
+  \rho\left(\cd{\vct u}\right) &= -\grad p + \mu\lapl\vct u
+    + \rho\vct f + \funssf.
+\end{align}
+
+\section{Fluid-fluid interface conditions}
+The surface-tension force and the jump in viscosity and density across the
+interface $\Gamma$ lead to a set of interface conditions that must be satisfied
+along the interface $\Gamma$.  The following is a brief derivation of these
+conditions.
+
+First, we only consider flows where there is no mass transfer, which implies
+that
+\begin{equation}
+  \jmp{\vct u}\cdot\vct n = 0,
+\end{equation}
+where $\jmp{\cdot}$ denotes the jump at the interface, for instance $\jmp{\mu}
+= \mu_2 - \mu_1$.  Further, for viscous flows there is no slip at the
+interface, and thus the tangential velocity component of the two fluids must be
+equal at the interface,
+\begin{equation}
+  \jmp{\vct u}\cdot\vct t = 0.
+\end{equation}
+It follows that
+\begin{align}
+  \label{eq:jmpu}
+  \jmp{\vct u} &= 0, \\
+  \label{eq:jmpJut}
+  \jmp{\grad \vct u}\cdot\vct t &= 0.
+\end{align}
+The latter is a direct consequence of the former.  Both fluids are
+incompressible, which gives the trivial identity $\jmp{\div\vct u} = 0$.  If we
+use the identity
+\begin{equation}
+  \div\vct u
+    = \vct n\cdot\grad\vct u\cdot\vct n + \vct t\cdot\grad\vct u\cdot\vct t
+  \label{eq:divuident}
+\end{equation}
+together with \eqref{eq:jmpJut} we get
+\begin{equation}
+  \vct n\cdot\jmp{\grad\vct u}\cdot\vct n = 0,
+  \label{eq:jmpngradun}
+\end{equation}
+which means that the normal component of the normal derivative of the velocity
+field is continuous across the interface.  Note that in \eqref{eq:divuident}
+and in similar expressions in the following, the nabla operator is only applied
+to $\vct u$, not the normal and tangential vectors that follow.

+  \end{tikzpicture}
+  \caption{A sketch of the control volume $\Omega_\epsilon$ that covers the
+    interface, $\Gamma$.}
+  \label{fig:domain_omega_epsilon}
+\end{figure}%
+Next, we consider the conservation of momentum.  We define a control volume
+\begin{equation}
+  \Omega_{\epsilon} = \set{\vct x \in \Omega}{\min_{\vct x_I \in \Gamma}|\vct
+    x - \vct x_I| \leq \epsilon},
+\end{equation}
+where $\epsilon > 0$, see \cref{fig:domain_omega_epsilon}.  We then integrate
+the Cauchy equation \eqref{eq:cauchy_equation} with the added singular
+surface-force term over the domain~$\Omega_\epsilon$,
+\begin{multline}
+  \intoepdx{\rho\td{\vct u}}
+    = \intoepdx{\div\tenstr} + \intoepdx{\rho\vct f} \\
+      + \intoepdx{ \int_{\Gamma}\sigma\kappa\vct n\delta(\vct x - \vct
+        x_I(\vct s))\dif\vct s}.
+\end{multline}
+Here $\tdi{\vct u} = \partial\vct u/\partial t + \vct u\cdot\grad\vct u$
+denotes the convective derivative.  Now we apply the Gauss theorem and change
+the order of integration in the last term to obtain
+\begin{equation}
+  \intoepdx{\rho\td{\vct u}} = \intdoepds{\tenstr\cdot\vct n}
+    + \intoepdx{\rho\vct f} + \int_\Gamma\sigma\kappa\vct n\dif\vct s.
+\end{equation}
+If we let $\epsilon$ go to zero, the left-hand side and the second term on the
+right-hand side vanish, and we get
+\begin{equation}
+  0 = \int_\Gamma\left( \jmp{\tenstr}\cdot\vct n + \sigma\kappa\vct
+    n \right)\dif s.
+  \label{eq:stressjumpint}
+\end{equation}
+Since the derivation above is also valid for any subset of $\Omega_\epsilon$
+containing a part of $\Gamma$, \eqref{eq:stressjumpint} must hold for any part
+of $\Gamma$.  Therefore
+\begin{equation}
+  0 = \jmp{\vct T}\cdot\vct n + \sigma\kappa\vct n.
+\end{equation}
+With $\vct T = -p\vct I + 2\mu\vct D$ we finally get the interface condition
+for the stresses,
+\begin{equation}
+  \label{eq:stress_jump}
+  \jmp{p}\vct n - \jmp{2\mu\tenD}\cdot\vct n = \sigma\kappa\vct n.
+\end{equation}
+The surface tension force is seen to introduce a discontinuity in the normal
+stresses across the interface.  The tangential stresses are continuous.
+
+\section{Interface conditions for the pressure and the viscous term}
+The previous section gave a brief derivation of the interface conditions for
+immiscible and incompressible two-phase flow without mass transfer.  In order
+to use these conditions for the discretization of the Navier-Stokes equations
+\eqref{eq:ns1} and \eqref{eq:ns2}, we need to rewrite them into a more suitable
+form.  In particular, we want to find explicit expressions for the jump in the
+pressure $\jmp p$ and the viscous term $\jmp{\mu\grad\vct u}$.  The following
+derivation is based on \cite{Hansen05} and \cite{Kang00}.
+
+First, a jump condition for the pressure is obtained by taking the inner
+product of \eqref{eq:stress_jump} with the normal vector $\vct n$,
+\begin{equation}
+  \jmp p = \vct n\cdot\jmp{2\mu\tenD}\cdot\vct n + \sigma\kappa
+      = 2\jmp{\mu}\vct n\cdot \grad\vct u \cdot\vct n
+        + \sigma\kappa,
+  \label{eq:jump_pressure}
+\end{equation}
+where \eqref{eq:jmpngradun} was used for the second equality.
+
+To find the jump in the viscous term, it is first decomposed into an interface
+normal coordinate system as
+\begin{equation}
+  \begin{split}
+    \jmp{\mu\grad\vct u} &=
+  \left(\vct n\cdot\jmp{\mu\grad\vct u}\cdot\vct n\right)\vct n\otimes\vct n +
+  \left(\vct t\cdot\jmp{\mu\grad\vct u}\cdot\vct t\right)\vct t\otimes\vct t
+        \\ &\quad+
+  \left(\vct n\cdot\jmp{\mu\grad\vct u}\cdot\vct t\right)\vct n\otimes\vct t +
+  \left(\vct t\cdot\jmp{\mu\grad\vct u}\cdot\vct n\right)\vct t\otimes\vct n,
+  \end{split}
+\end{equation}
+where $\otimes$ denotes the dyadic product.  We already showed that
+$\jmp{\grad\vct u}\cdot\vct t = 0$ and $\vct n\cdot\jmp{\grad\vct u}\cdot\vct
+n = 0$, cf.\ \eqref{eq:jmpJut} and \eqref{eq:jmpngradun}, which gives
+\begin{align}
+  \vct n\cdot\jmp{\mu\grad\vct u}\cdot\vct n &=
+    \jmp{\mu}\,\vct n\cdot\grad\vct u\cdot\vct n, \\
+  \vct t\cdot\jmp{\mu\grad\vct u}\cdot\vct t &=
+    \jmp{\mu}\,\vct t\cdot\grad\vct u\cdot\vct t, \\
+  \vct n\cdot\jmp{\mu\grad\vct u}\cdot\vct t &=
+    \jmp{\mu}\,\vct n\cdot\grad\vct u\cdot\vct t.
+\end{align}
+We then take the inner product of \eqref{eq:stress_jump} with $\vct t$, which
+gives
+\begin{equation}
+  \vct t\cdot\jmp{\mu\left(\grad\vct u + (\grad\vct u)^T \right)}\cdot\vct n
+  = \vct t\cdot\jmp{\mu\grad\vct u} \cdot\vct n
+    + \jmp{\mu}\vct n\cdot\grad\vct u \cdot\vct t
+  = 0,
+\end{equation}
+or
+\begin{equation}
+  \vct t\cdot\jmp{\mu\grad\vct u}\cdot\vct n =
+    - \jmp{\mu}\vct n\cdot\grad\vct u \cdot\vct t.
+\end{equation}
+The jump in the viscous term becomes
+\begin{multline}
+  \jmp{\mu\grad\vct u} = \jmp{\mu} \Big(
+       (\vct n\cdot\grad\vct u\cdot\vct n)\vct n\otimes\vct n
+     + (\vct n\cdot\grad\vct u\cdot\vct t)\vct n\otimes\vct t \\
+     - (\vct n\cdot\grad\vct u\cdot\vct t)\vct t\otimes\vct n
+     + (\vct t\cdot\grad\vct u\cdot\vct t)\vct t\otimes\vct t \Big).
+\end{multline}
+This can be simplified further by noting that
+\begin{equation}
+  (\grad\vct u\cdot t)\otimes\vct t
+  = (\vct n\cdot\grad\vct u\cdot\vct t)\vct n\otimes\vct t
+    + (\vct t\cdot\grad\vct u\cdot\vct t)\vct t\otimes\vct t.
+\end{equation}
+Thus we obtain the expression for the jump in the viscous term that has been
+used in the present work,
+\begin{multline}
+  \jmp{\mu\grad\vct u} = \jmp{\mu} \Big(
+       (\vct n\cdot\grad\vct u\cdot\vct n)\vct n\otimes\vct n
+     - (\vct n\cdot\grad\vct u\cdot\vct t)\vct t\otimes\vct n \\
+     + (\grad\vct u\cdot\vct t)\otimes\vct t \Big).
+  \label{eq:jumptens}
+\end{multline}
+
+\section{Summary}

+\chapter{Numerical methods}
+\label{chap:numerical-methods}
+This chapter describes the numerical methods that have been used in this thesis
+to solve the Navier-Stokes equations for two-phase flow.  First, a brief
+introduction to the level-set method is given, which is followed by an outline
+of the two projection methods that have been used to solve the Navier-Stokes
+equations.  The spatial and temporal discretization methods are then
+summarized, and at the end of the chapter the new methods to calculate the
+curvature and the normal vectors are presented.
+
+\section{The level-set method}
+\label{sec:level-set}
+In order to solve the Navier-Stokes equations for two-phase flow, we need to
+know the location of the interface.  The level-set method proposed by
+\citet{Osher88} allows us to capture the interface location as the zero level
+set of the level-set function $\varphi(\vct x,t)$.  The level-set function is
+typically defined as a signed-distance function,
+\begin{equation}
+  \varphi(\vct x,t) = \begin{cases}
+     d(\vct x,t) & \text{if } \vct x\in\Omega_2, \\
+    -d(\vct x,t) & \text{if } \vct x\in\Omega_1, \\
+  \end{cases}
+\end{equation}
+where $d(\vct x,t)$ is the shortest distance to the interface $\Gamma$,
+\begin{equation}
+  d(\vct x,t) = \min_{\vct x_I \in \Gamma} |\vct x - \vct x_I|.
+\end{equation}
+Thus the interface can be defined implicitly as
+\begin{equation}
+  \Gamma(t) = \set{\vct x\in\Omega}{\varphi(\vct x,t)=0},
+              \quad t\in \mathbb R^+.
+\end{equation}
+
+The position of the interface is updated by solving an advection equation for
+$\varphi$,
+\begin{equation}
+  \label{eq:ls_adeq}
+  \pdt{\varphi} + \vct{\hat u}\cdot\grad\varphi = 0,
+\end{equation}
+where $\vct{\hat u}$ is the velocity at the interface extended to the entire
+domain.  We extend the interface velocity through solving
+a velocity-extrapolation equation,
+\begin{equation}
+  \label{eq:ls_velextr}
+  \pd{\vct{\hat u}}{\tau} + S(\varphi)\vct n\cdot\grad\vct{\hat u} = 0,
+  \quad \vct{\hat u}_{\tau=0} = \vct u,
+\end{equation}
+to steady state, cf.\ \cite{Adalsteinsson99,Zhao96}.  Here $\tau$ is
+a pseudo-time and $S$ is a smeared sign function which is equal to zero at the
+interface,
+\begin{equation}
+  S(\varphi) = \frac{\varphi}{\sqrt{\varphi^2+2\Delta x^2}}.
+\end{equation}
+
+When we solve the level-set equation \eqref{eq:ls_adeq}, the non-uniform
+advection will distort the signed-distance property of the level-set function,
+and numerical dissipation error adds to this distortion.  The level-set
+function is therefore reinitialized regularly by solving
+\begin{equation}
+  \label{eq:ls_reinit}
+  \begin{split}
+    \pd{\varphi}{\tau} + S(\varphi_0)(|\grad\varphi|-1) &= 0, \\
+    \varphi(\vct x,0) &= \varphi_0(\vct x),
+  \end{split}
+\end{equation}
+to steady state as proposed by \citet{Sussman94}.  The level-set function just
+before initialization is used as the initial condition $\varphi_0$.
+
+The level-set equations \eqref{eq:ls_adeq}, \eqref{eq:ls_velextr}, and
+\eqref{eq:ls_reinit} are discretized in time and space as described in the
+following sections.  The method presented by \citet{Adalsteinsson95} is used to
+improve the computational speed.  The method is often called the narrow-band
+method, since the level-set function is only updated in a narrow band across
+the interface at each time step.
+
+One of the advantages of the level-set method is that normal vectors and
+curvatures can be readily calculated from the level-set function, that is,
+\begin{align}
+  \label{eq:norm}
+  \vct n &= \frac{\grad\varphi}{|\grad\varphi|}, \\
+  \label{eq:curv}
+  \kappa &= \div\left(\frac{\grad\varphi}{|\grad\varphi|}\right).
+\end{align}
+
+\section{Projection methods}
+\label{sec:projection-method}
+We have employed two different projection methods in this thesis to solve the
+incompressible Navier-Stokes equations for two-phase flow \eqref{eq:ns1} and
+\eqref{eq:ns2}.  Papers A, B, and C used the direct projection
+scheme~1~(DP1)~\cite{Hansen05}, and Paper D used the more standard Chorin
+projection method \cite{Chorin68}.
+
+The projection methods are a family of methods for the solution of the
+incompressible Navier-Stokes equations that are based on the Helmholtz-Hodge
+theorem.  This theorem states that an arbitrary vector field can be decomposed
+into a divergence-free part and a rotation-free part.  That is, any vector
+field $\vct a$ can be written as
+\begin{equation}
+  \vct a = \vct a' + \grad\psi,
+\end{equation}
+where $\vct a'$ is a vector with $\div\vct a' = 0$ and $\psi$ is a scalar
+potential.  The proof of this theorem can be found in for instance
+\cite[§3.44]{Aris89} or \cite{Chorin00}.
+
+\subsection{The direct projection scheme 1}
+The DP1 was developed by \citet{Hansen05} and is based on a direct application
+of the Helmholtz-Hodge theorem.  We assume that the velocity $\vct u$ is
+sufficiently smooth, and then rewrite \eqref{eq:navier-stokes-2} to get
+\begin{equation}
+  \label{eq:divFreeVel}
+  \pdt{\vct u} = \vct w - \frac{\grad p}{\rho},
+\end{equation}
+where
+\begin{equation}
+  \vct w = - (\vct u\cdot\grad)\vct u + \nu\grad^2\vct u + \vct f.
+  \label{eq:continuousRightHandVector}
+\end{equation}
+The divergence of \eqref{eq:divFreeVel} yields a Poisson equation for the
+pressure,
+\begin{equation}
+  \div\left(\frac{\grad p}{\rho}\right) = \div\vct w.
+  \label{eq:PoissonDP1}
+\end{equation}
+The DP1 scheme follows from a direct numerical discretization of the above
+equations.  First, $\vct w$ is calculated with
+\eqref{eq:continuousRightHandVector}.  Then the pressure is found by solving
+the Poisson equation \eqref{eq:PoissonDP1}.  Finally, an Euler step is used to
+solve \eqref{eq:divFreeVel}, that is,
+\begin{equation}
+  \vct u^{n+1} = \vct u^n + \Delta t\left(\vct w - \frac{\grad p}{\rho}\right).
+  \label{eq:dp1-update}
+\end{equation}
+
+\subsection{The Chorin projection method}
+The Chorin projection method was presented by \citet{Chorin68}, and is today
+one of the standard methods for solving the Navier-Stokes equations, e.g.\
+\cite{Walker12}.  The method is briefly presented in the following.
+
+Let $\Delta t$ be the time step, and consider the discretization of the
+momentum equation \eqref{eq:navier-stokes-2} with the forward Euler method,
+\begin{equation}
+  \frac{\vct u^{n+1} - \vct u^n}{\Delta t}
+  = -\vct u^n\cdot\grad\vct u^n
+    - \frac{\grad p^{n+1}}{\rho} + \frac\mu\rho\lapl\vct u^n + \vct f,
+  \label{eq:discmomeq}
+\end{equation}
+where $\vct u^n\equiv\vct u(\vct x,n\Delta t)$ and $p^n\equiv p(\vct x,n\Delta
+t)$ are assumed known at time level $n$.  Note that the pressure gradient is
+evaluated at time level $n+1$.  Next, to solve \eqref{eq:discmomeq} in two
+steps, we introduce the intermediate velocity field $\vct u^\star$,
+\begin{equation}
+  \frac{\vct u^{n+1} - \vct u^\star + \vct u^\star - \vct u^n}{\Delta t}
+  = -\vct u^n\cdot\grad\vct u^n
+    - \frac{\grad p^{n+1}}{\rho} + \frac\mu\rho\lapl\vct u^n + \vct f,
+\end{equation}
+which is chosen such that
+\begin{align}
+  \label{eq:ustar}
+  \frac{\vct u^\star - \vct u^n}{\Delta t}
+    &= -\vct u^n\cdot\grad\vct u^n + \frac\mu\rho\lapl\vct u^n + \vct f, \\
+  \label{eq:unext}
+  \frac{\vct u^{n+1} - \vct u^\star}{\Delta t} &= - \frac{\grad p^{n+1}}{\rho}.
+\end{align}
+From \eqref{eq:ustar} we get an explicit expression for $\vct u^\star$,
+\begin{equation}
+  \vct u^{\star} = \vct u^n
+    + \Delta t\left(-\vct u^n\cdot\grad\vct u^n
+        + \frac\mu\rho\,\lapl\vct u^n + \vct f\right).
+\end{equation}
+Next, the divergence of \eqref{eq:unext} and $\div\vct u^{n+1} = 0$ yields
+a Poisson equation for the pressure,
+\begin{equation}
+  \div\left(\frac{\grad p^{n+1}}{\rho}\right)
+    = \frac{\div\vct u^\star}{\Delta t}.
+  \label{eq:PoissonChorin}
+\end{equation}
+Finally, we obtain for \eqref{eq:unext}
+\begin{equation}
+  \vct u^{n+1} = \vct u^\star - \Delta t\frac{\grad p^{n+1}}{\rho}.
+  \label{eq:velcorrection}
+\end{equation}
+
+\section{Spatial discretization}
+\label{sec:x-discr}
+The governing equations \eqref{eq:ns1}, \eqref{eq:ns2}, \eqref{eq:ls_adeq},
+\eqref{eq:ls_velextr}, and \eqref{eq:ls_reinit} are discretized on a staggered
+grid~\cite{Harlow65}, where the scalar values are located at the cell centres
+and the vector values are located at the cell edges, see
+\cref{fig:staggered-grid}.  The domain boundary coincides with cell edges, and
+the fixed grid spacing is $\Delta x$ in the $x$ direction and $\Delta y$ in the
+$y$ direction.

+    &= \frac{p_{i+1,j} - p_{i,j}}{\Delta x}, \\
+  \left. G_y p \right|_{i,j+\frac 1 2}
+    &= \frac{p_{i,j+1} - p_{i,j}}{\Delta y}, \\
+  \left. \vct D \cdot \vct u \right|_{i,j}
+    &=   \frac{u_{i+1/2,j} - u_{i-1/2,j}}{\Delta x}
+       + \frac{v_{i,j+1/2} - v_{i,j-1/2}}{\Delta y}, \\
+  \left. Lp \right|_{i,j}
+    &=   \frac{p_{i+1,j} - 2p_{i,j} + p_{i-1,j}}{(\Delta x)^2}
+       + \frac{p_{i,j+1} - 2p_{i,j} + p_{i,j-1}}{(\Delta y)^2},
+\end{align}
+respectively.  Here $\vct u = (u,v)$ is a vector and $p$ is a scalar.  Note
+that the gradient of a scalar is a vector and has values located at the cell
+edges.  These definitions are consistent with the staggered grid, since the
+gradient returns a vector with components defined on the cell faces, while the
+divergence and the Laplacian returns a scalar defined at the cell centres.
+
+\subsection{Advective terms}
+The advective terms, $\vct u\cdot\grad\vct u$ in the momentum equation
+\eqref{eq:ns2} and $\vct{\hat u}\cdot\grad\varphi$ in the level-set equation
+\eqref{eq:ls_adeq}, and the normal derivative $\vct n\cdot\grad\vct{\hat u}$ in
+the velocity-extrapolation equation \eqref{eq:ls_velextr} are discretized with
+the weighted essentially non-oscillatory (WENO) scheme, cf.~\cite{Fedkiw99}
+and~\cite{Jiang96}.  The WENO scheme is a high-order upwind scheme that is
+fifth-order accurate in smooth regions.  In nonsmooth regions the accuracy is
+reduced to a minimum of third order.  The following is a brief outline of the
+WENO scheme.
+
+First, when we calculate the advective term for the velocity, the vector
+components are required on all cell edges.  That is, we must interpolate the
+$x$-component of the velocity to the location of the $y$-component of the
+velocity and vice versa.  To do this we use a linear interpolation,
+\begin{align}
+  u_{i,j+\frac 1 2} &= \frac 1 4\left(
+      u_{i-\frac 1 2,j  } + u_{i-\frac 1 2,j+1}
+    + u_{i+\frac 1 2,j+1} + u_{i+\frac 1 2,j  } \right), \\
+  v_{i+\frac 1 2,j} &= \frac 1 4\left(
+      v_{i,  j-\frac 1 2} + v_{i+1,j-\frac 1 2}
+    + v_{i+1,j+\frac 1 2} + v_{i  ,j+\frac 1 2} \right).
+\end{align}
+
+Similarly, when we calculate the advective term for the level-set function
+$\varphi$, we first interpolate the velocity to the scalar grid,
+\begin{align}
+  u_{i,j} &= \frac 1 2\left( u_{i+\frac 1 2,j} + u_{i-\frac 1 2,j} \right), \\
+  v_{i,j} &= \frac 1 2\left( v_{i,j+\frac 1 2} + v_{i,j-\frac 1 2} \right).
+\end{align}
+
+We now consider the WENO scheme for the advective operator in 1D at the point
+$x_{i+\frac 1 2}$.  The scheme extends naturally to higher dimensions.  First,
+if $u_{i+\frac 1 2} = 0$, then
+\begin{equation}
+  \left. u\pd u x \right|_{i+\frac 1 2} = 0.
+\end{equation}
+Otherwise we need to calculate a set of five differences that depend on the
+upwind direction.  The differences are denoted $\Delta v_k$ for $k=1,\dots,5$.
+If $u_{i+\frac 1 2}>0$, then we calculate
+\begin{equation}
+  \Delta v_k = \frac{u_{i+\frac{2k-5} 2} - u_{i+\frac{2k-7} 2}}{\Delta x}.
+\end{equation}
+Otherwise if $u_{i+\frac 1 2}<0$, we calculate
+\begin{equation}
+  \Delta v_k = \frac{u_{i-\frac{2k-9} 2} - u_{i-\frac{2k-7} 2}}{\Delta x}.
+\end{equation}
+Next we calculate expressions for the smoothness of three substencils,
+\begin{align}
+  S_1 &= \frac{13}{12}(\Delta v_1 - 2\Delta v_2 + \Delta v_3)^2
+    + \frac 1 4 (\Delta v_1 - 4\Delta v_2 + 3\Delta v_3)^2, \\
+  S_2 &= \frac{13}{12}(\Delta v_2 - 2\Delta v_3 + \Delta v_4)^2
+    + \frac 1 4 (\Delta v_2 - \Delta v_4)^2, \\
+  S_3 &= \frac{13}{12}(\Delta v_3 - 2\Delta v_4 + \Delta v_5)^2
+    + \frac 1 4 (3\Delta v_3 - 4\Delta v_4 + \Delta v_5)^2,
+\end{align}
+where a small $S$ indicates a smooth substencil.  These smoothness factors are
+then used to compute weights for the substencils,
+\begin{equation}
+  w_k = \frac{b_k}{b_1+b_2+b_3},
+\end{equation}
+for $k = 1,2,3$, where
+\begin{equation}
+  b_1 = \frac 1 {10}\frac 1 {(\epsilon+S_1)^2},\quad
+  b_2 = \frac 6 {10}\frac 1 {(\epsilon+S_2)^2},\quad
+  b_3 = \frac 3 {10}\frac 1 {(\epsilon+S_3)^2}.
+\end{equation}
+Here $\epsilon$ is a regularization parameter that is used to avoid division by
+zero.  We have used $\epsilon = 10^{-6}$ in this work.  Finally, the WENO
+scheme for the gradient becomes
+\begin{multline}
+  \left. \pd u x \right|_{i+\frac 1 2} \simeq
+      w_1\left(\frac 1 3\Delta v_1 - \frac 7 6\Delta v_2
+        + \frac{11} 6 \Delta v_3\right) \\
+    + w_2\left(-\frac 1 6\Delta v_2 + \frac 5 6\Delta v_3
+        + \frac 1 3 \Delta v_4\right) \\
+    + w_3\left(\frac1 3\Delta v_3 + \frac 5 6\Delta v_4
+        - \frac 1 6 \Delta v_5\right).
+\end{multline}
+
+\subsection{The viscous term}
+The viscous term $\mu\lapl\vct u$ in the Navier-Stokes equations is discretized
+by standard second-order central differences using the ghost-fluid method
+(GFM)~\cite{Fedkiw99,Kang00,Liu00}.  This method includes the jump in the
+viscous term at the interface \eqref{eq:jumptens} in the discretization stencil
+in a sharp manner.
+
+In the following we present the GFM scheme in the one-dimensional case.  The
+extension to higher dimensions is straightforward.  In order to simplify the
+notation, we omit the half indices and let $k\equiv i+\frac 1 2$.  Further, we
+consider a general case where
+\begin{equation}
+  \jmp u = a_\Gamma, \qquad \jmp{\mu\pd u x} = b_\Gamma.
+\end{equation}
+For the viscous term, $a_\Gamma = 0$, cf.\ \eqref{eq:jmpu}, and $b_\Gamma$ is
+given by the jump tensor~\eqref{eq:jumptens}.  The jump tensor is calculated at
+the cell centres near the interface with the second-order central-difference
+scheme.  It is then interpolated linearly to the cell edges, from where it is
+again interpolated linearly to the interface when needed.
+
+If the interface does not cross the stencil, then the GFM scheme reduces to the
+standard second-order central-difference stencil.  Else there are four
+stencils, depending on the location of the interface.  One such interface
+configuration is sketched in \cref{fig:gfm-scheme-example}.  In all the
+stencils, $\theta$ is defined as the relative distance from the interface to
+the node on the left, for instance
+\begin{equation}
+  \theta = \frac{|\varphi_{k}|}{|\varphi_{k}| + |\varphi_{k+1}|},
+\end{equation}
+where $\varphi_k$ and $\varphi_{k+1}$ are the level-set function values
+linearly interpolated to the vector grid.  The four stencils are given below,
+where $h\equiv\Delta x$.
+\begin{enumerate}
+  \item Phase 1 is to the left and interface lies between $k$ and $k+1$:
+    \begin{align}
+      \begin{split}
+        \left.\pd{} x\left(\mu\pd u x\right)\right|_{x_k}
+          &= \frac{\hat\mu\left(u_{k+1} - u_{k}\right)
+                 - \mu_1\left(u_{k} - u_{k-1}\right)}{h^2} \\
+          &\qquad
+             - \frac{\hat\mu a_\Gamma}{h^2}
+             - \frac{\hat\mu b_\Gamma (1-\theta)}{\mu_2 h},
+      \end{split} \\

+          &= \frac{\mu_2\left(u_{k+1} - u_{k}\right)
+                - \hat\mu\left(u_{k} - u_{k-1}\right)}{h^2} \\

+      \end{split} \\
+      \hat\mu &= \frac{\mu_1\mu_2}{\theta\mu_2 + (1-\theta)\mu_1}.
+    \end{align}
+  \item Phase 2 is to the left and interface lies between $k$ and $k+1$:
+    \begin{align}
+      \begin{split}
+        \left.\pd{} x\left(\mu\pd u x\right)\right|_{x_k}
+          &= \frac{\hat\mu\left(u_{k+1} - u_{k}\right)
+                - \mu_2\left(u_{k} - u_{k-1}\right)}{h^2} \\
+          &\qquad
+            + \frac{\hat\mu a_\Gamma}{h^2}
+            + \frac{\hat\mu b_\Gamma (1-\theta)}{\mu_1 h},
+      \end{split} \\
+      \hat\mu &= \frac{\mu_1\mu_2}{\theta\mu_1 + (1-\theta)\mu_2}.
+    \end{align}
+  \item Phase 2 is to the left and interface lies between $k-1$ and $k$:

+\subsection{Pressure Poisson equation}
+\label{sec:pressure-poisson}
+The Laplace operator in the Poisson equations \eqref{eq:PoissonDP1} and
+\eqref{eq:PoissonChorin} is also discretized by standard second-order central
+differences using the GFM~\cite{Kang00,Liu00}.  The GFM was discussed in the
+previous section, where stencils were given for the viscous term in the
+one-dimensional case.  For the pressure, the stencils are the same except we
+use $p$ instead of $u$, and $1/\rho$ and $1/\hat\rho$ instead of $\mu$ and
+$\hat\mu$.  To find the jump in the pressure at the interface, $\jmp
+p = a_\Gamma$, the jump condition \eqref{eq:jump_pressure} is calculated at the
+cell centres and then interpolated to the interface.  In addition, we use that
+$b_\Gamma = 0$, which is justified by \citet[Section~3.7]{Kang00}.
+
+The resulting linear system for the pressure is solved with a solver from the
+Portable, Extensible Toolkit for Scientific Computation (PETSc)~\cite{PETSc}.
+PETSc makes available a large selection of solvers.  In most cases, we used the
+direct solver based on LU factorisation or the conjugate gradient method with
+incomplete Cholesky factorisation.  In some cases, we used the GMRES solver
+with a preconditioner, either incomplete LU factorisation or an algebraic
+multigrid method.  See \cite{PETSc} for more details and a list of available
+methods, and see for example~\cite{Iserles09} or~\cite{Saad03} for an
+introduction to linear solvers.
+
+Finally, the gradient of the pressure, used in \eqref{eq:divFreeVel} and
+\eqref{eq:velcorrection}, is also calculated with the GFM.  In one dimension,
+the stencil is
+\begin{align}
+  \left. \frac 1 \rho \pd p x\right|_{i+\frac 1 2}
+           &= \frac 1 {\hat\rho} \frac{(p_{i+1} - a_\Gamma) - p_i} h, \\
+  \hat\rho &= \theta\rho_1 + (1-\theta)\rho_2,
+\end{align}
+if $\phi_i\leq 0$ and $\phi_{i+1}>0$, or else
+\begin{align}
+  \left. \frac 1 \rho \pd p x\right|_{i+\frac 1 2}
+           &= \frac 1 {\hat\rho} \frac{(p_{i+1} + a_\Gamma) - p_i} h, \\
+  \hat\rho &= \theta\rho_2 + (1-\theta)\rho_1,
+\end{align}
+where
+\begin{equation}
+  \theta = \frac{|\varphi_{i}|}{|\varphi_{i}| + |\varphi_{i+1}|}.
+\end{equation}
+
+\section{Temporal discretization}
+\label{sec:t-discr}
+The temporal discretization is done with the explicit strong
+stability-preserving Runge-Kutta (SSP-RK) schemes, see
+\cite{Ketcheson05,Shu88}.  The idea behind the SSP-RK schemes is to preserve
+the stability of a low-order method when it is extended to higher order.  It is
+argued in \cite{Gottlieb01} that if one extends the forward Euler method, which
+is total variation diminishing (TVD) for a suitable discretization of a scalar
+conservation law, to a non-SSP higher-order method, then overshoots may occur
+at discontinuities.
+
+An SSP-RK method can be written as a convex sum of explicit Euler steps with
+time step $\Delta t$,
+\begin{equation}
+  \mathcal E\left(x^n\right) = x^n + \Delta t \mathcal F(x^n,t^n).
+\end{equation}
+where $\mathcal F$ is the residual of the PDE to be solved.  In this thesis we
+have used two methods:  The third-order three-stage SSP-RK method~\cite{Shu88},
+\begin{equation}
+  \begin{split}
+    x^{(1)} &= \mathcal E\left(x^n\right), \\
+    x^{(2)} &= \frac 3 4 x^n + \frac 1 4\mathcal E\left(x^{(1)}\right), \\
+    x^{n+1} &= \frac 1 3 x^n + \frac 2 3\mathcal E\left(x^{(2)}\right),
+  \end{split}
+  \label{eq:ssprk33}
+\end{equation}
+and the third-order four-stage SSP-RK method~\cite{Kraaijevanger91},
+\begin{equation}
+  \begin{split}
+    x^{(1)} &= \frac 1 2 x^n + \frac 1 2\mathcal E\left(x^n\right), \\
+    x^{(2)} &= \frac 1 2 x^{(1)} + \frac 1 2\mathcal E\left(x^{(1)}\right), \\
+    x^{(3)} &= \frac 2 3 x^n + \frac 1 6 x^{(2)}
+               + \frac 1 6\mathcal E\left(x^{(2)}\right), \\
+    x^{n+1} &= \frac 1 2 x^{(3)} + \frac 1 2\mathcal E\left(x^{(3)}\right).
+  \end{split}
+  \label{eq:ssprk34}
+\end{equation}
+
+The semi-discretized velocity-extrapolation equation \eqref{eq:ls_velextr} and
+level-set reinitialization equation \eqref{eq:ls_reinit} can be written as
+systems of ordinary differential equations (ODEs) of the form
+\begin{equation}
+  \od{\vct \psi} \tau = \vct F(\vct\psi,\tau),
+\end{equation}
+where $\vct\psi$ is a vector containing the discrete variables and $\vct F$
+contains the spatially discretized terms.  The explicit Euler step becomes
+\begin{equation}
+  \mathcal E(\vct\psi^n) = \vct\psi^n + \Delta\tau \vct F(\vct\psi^n,\tau^n).
+\end{equation}
+In this thesis, these equations are solved with the third-order four-stage
+SSP-RK method \eqref{eq:ssprk34}.  The four-stage method is used because it is
+more accurate than the three-stage method.  We wanted to make sure that the
+error is mainly dominated by the spatial discretization.
+
+The semi-discretized Navier-Stokes equations \eqref{eq:navier-stokes-1} and
+\eqref{eq:navier-stokes-2} are solved together with the level-set advection
+equation \eqref{eq:ls_adeq} with the third-order three-stage SSP-RK method
+\eqref{eq:ssprk33}.  Here an explicit Euler step $\mathcal E(\vct
+u^n,\varphi^n)$ consists of the following steps:
+\begin{enumerate}
+  \item Calculate the curvature and the normal vectors from $\varphi^n$ with
+    one of the methods described in \cref{sec:curvature}.
+  \item Calculate the intermediate velocity field, either $\vct w$
+    \eqref{eq:continuousRightHandVector} or $\vct u^\star$ \eqref{eq:ustar}.
+  \item Solve the Poisson equation \eqref{eq:PoissonDP1} or
+    \eqref{eq:PoissonChorin} for the pressure as described in
+    \cref{sec:pressure-poisson}.
+  \item Correct the velocity field with either \eqref{eq:dp1-update} or
+    \eqref{eq:velcorrection}.
+  \item Advect the level-set function $\varphi^n$ with \eqref{eq:ls_adeq}.
+\end{enumerate}
+
+\section{Time step restriction}
+\label{sec:deltaT}
+We employ the Courant-Friedrich-Lewy~(CFL) condition to allow adaptive time
+stepping and to enforce stability.  The CFL condition that is used in this
+thesis is
+\begin{equation}
+  \Delta t = \frac{C}{\frac{C_c + C_v} 2
+             + \sqrt{(C_c + C_v)^2 + 4C_g^2 + 4C_s^2}},
+\end{equation}
+where the CFL restriction $C<1$, and $C_c$, $C_v$, $C_s$, and $C_g$ represent
+the contributions from the convective term, the viscous stresses, the surface
+tension, and the gravity, respectively,
+\begin{align}
+  C_c &=  \frac{\max_{i,j}|u_{i,j}|}{\Delta x}
+        + \frac{\max_{i,j}|v_{i,j}|}{\Delta y}, \\
+  C_v &= 2\max\left(\frac{\mu_1}{\rho_1},\frac{\mu_2}{\rho_2}\right)
+         \left(\frac{1}{\Delta x^2} + \frac{1}{\Delta y^2}\right), \\
+  C_s &= \sqrt{\frac{\sigma\max_{i,j}|\kappa_{i,j}|}
+                    {\max(\rho_1,\rho_2)\min(\Delta x^2,\Delta y^2)}}, \\
+  C_g &= \sqrt{\frac{|g_x|}{\Delta x} + \frac{|g_y|}{\Delta y}}.
+\end{align}
+This CFL condition is discussed in more detail by~\citet{Lervag08}, and it is
+based on the condition by \citet{Kang00}.
+
+\section{Axisymmetry}
+For axisymmetric flow, the governing equations \eqref{eq:ns1} and
+\eqref{eq:ns2} become
+\begin{equation}
+  \frac 1 r \pd{} r\left(r u\right) + \pd v z = 0,
+\end{equation}
+\begin{multline}
+  \rho\left(\pdt u + u\pd u r + v\pd u z\right) = -\pd p r \\
+    + \mu\left(\frac 1 r \pd{} r\left(r \pd u r\right)
+          + \pdd u z - \frac u {r^2}\right) + \rho f_r + {f_s}_r,
+\end{multline}
+and
+\begin{multline}
+  \rho\left(\pdt v + u\pd v r + v\pd v z\right) = -\pd p z \\
+    + \mu\left(\frac 1 r \pd{} r\left(r \pd v r\right)
+      + \pdd v z\right) + \rho f_z + {f_s}_z.
+\end{multline}
+Here $u$ and $v$ are the radial and axial velocity components, $f_r$ and $f_z$
+are the radial and axial body-force components, and ${f_s}_r$ and ${f_s}_z$ are
+the radial and axial components of the singular surface force, respectively.
+The equations are solved as explained in the previous sections.
+
+\section{Discretization of the curvature and the normal vector}
+\label{sec:curvature}
+As stated in \cref{sec:level-set}, the normal vector \eqref{eq:norm} and the
+curvature \eqref{eq:curv} can be calculated from the level-set function as
+\begin{align*}
+  \vct n &= \frac{\grad\varphi}{|\grad\varphi|}, \\
+  \kappa &= \div\left(\frac{\grad\varphi}{|\grad\varphi|}\right).
+\end{align*}
+They are typically discretized with the standard second-order
+central-difference scheme, cf.\ \cite{Kang00,Sethian03,Xu06}.  The normal
+vector is calculated at the cell edges, and the curvature is calculated at the
+grid nodes.  The curvature is then interpolated to the interface where needed
+with linear interpolation, for instance with
+\begin{equation}
+  \kappa_\Gamma = \frac{|\varphi_{i,j}|\kappa_{i+1,j}
+  + |\varphi_{i+1,k}|\kappa_{i,j}}{|\varphi_{i,j}| + |\varphi_{i+1,j}|}.
+  \label{eq:curvature-gamma}
+\end{equation}
+
+If the level-set method is used to capture non-trivial geometries, then it will
+contain kink regions, that is, areas where the gradient of the level-set
+function is discontinuous.  \Cref{fig:level-set-function} shows a simple
+example of such a kink region for a level-set function in a one-dimensional
+domain that captures two interfaces, one on each side of $x_i$.  The kink at
+$x_i$ may lead to large errors both for the curvature and the normal vector if
+one is not careful.  Errors in the curvature lead to errors in the surface
+tension force and in the pressure, which in turn lead to errors in the
+interface evolution and in the two-phase flow.  Errors in the normal vector
+affect both the calculation of the viscous jump condition and the advection of
+the interface.  If the level-set method is used to study for example
+coalescence and breakup of drops, these errors may severely affect the
+simulations.

+
+This problem was to our knowledge first described by \citet{Smereka03}, who
+increase the numerical smoothing in the curvature discretization to lessen the
+effect.  Several non-smearing approaches have subsequently been developed.
+\citet{Macklin05} used the level-set method to study tumor growth, and they
+present a one-sided direction-difference scheme for the discretization of the
+normal vector and the curvature.  Later, \citet{Macklin06} presented an
+improved geometry-aware curvature discretization, where the curvature is
+calculated based on a local least-squares parametrisation of the interface.
+
+A different approach to avoid the kinks was presented by \citet{Salac08}.  They
+used a level-set extraction technique, where an extraction algorithm was used
+to reconstruct separate level-set functions for each distinct \emph{body}.  The
+term \emph{body} is used here to denote a subset of a given phase or fluid.
+For example, in the case of two drops of water colliding in air, the water
+drops would make two distinct bodies.  One can also avoid the extraction
+algorithm altogether by use of multiple marker functions for different bodies,
+see for instance \cite{Coyajee09,Kwakkel12}.  Note, however, that the latter
+approach means that the different bodies will not coalesce unless explicit
+action is made, cf.~\cite{Kwakkel13}.  Also, both of the approaches mentioned
+here fails to handle the problem of kinks from a single body.  That is, there
+may still be kink areas due to deformed bodies, for instance bodies with thin
+filaments or tails, or bodies shaped like horse shoes.
+
+In the following, we first present the direction-difference
+scheme~\cite{Macklin05}.  We then describe the curve-fitting discretization
+method and the local level-set extraction method.
+
+\subsection{Direction-difference scheme}
+\label{sec:dds}
+The direction-difference scheme (DDS) was introduced by \citet{Macklin05}.  It
+uses a quality function to ensure that the difference stencils never cross any
+kink regions.  The DDS is used in Papers A--C to calculate the normal vectors.
+However, in Paper C it is shown that the DDS does not always yield an accurate
+approximation of the normal vector.
+
+The basic strategy is to use a combination of central differences and one-sided
+differences based on the values of a quality function,
+\begin{equation}
+  Q(\vct x) = \left| 1 - |\grad\varphi(\vct x)|\right|.
+  \label{eq:quality}
+\end{equation}
+The quality function is approximated with central differences, and is used to
+detect the areas where the level-set function differs from the signed-distance
+function.  In the following, let $Q_{i,j} \equiv Q(\vct x_{i,j})$ and define
+a parameter $\eta>0$.  This threshold parameter is tuned such that the quality
+function will detect all the kinks.
+
+The quality function is used to define a direction function,
+\begin{equation}
+  \vct D(\vct x_{i,j}) = (D_x(\vct x_{i,j}), D_y(\vct x_{i,j})),
+\end{equation}
+where
+\begin{equation}
+  D_x(\vct x_{i,j}) = \begin{cases}
+    -1 & \text{if $Q_{i-1,j}<\eta$ and $Q_{i+1,j}\geq\eta$,} \\
+     1 & \text{if $Q_{i-1,j}\geq\eta$ and $Q_{i+1,j}<\eta$,} \\
+     0 & \text{if $Q_{i-1,j}<\eta$ and $Q_{i,j}<\eta$ and $Q_{i+1,j}<\eta$,} \\
+     0 & \text{if $Q_{i-1,j}\geq\eta$ and $Q_{i,j}\geq\eta$ and
+         $Q_{i+1,j}\geq\eta$,} \\
+     4 & \text{otherwise.}
+  \end{cases}
+  \label{eq:dirfunc}
+\end{equation}
+$D_y(\vct x_{i,j})$ is defined in a similar manner.  If $D_x(\vct x_{i,j})
++ D_y(\vct x_{i,j}) > 2$, then $\vct D(\vct x_{i,j})$ is chosen as the vector
+normal to $\grad\varphi(\vct x_{i,j})$.  It is normalized, and the sign is
+chosen such that it points in the direction of the best quality.  See
+\cite{Macklin05} for more details.
+
+The DDS is then defined as
+\begin{equation}
+  \partial_x f_{i,j} = \begin{cases}
+    \frac{f_{i,j} - f_{i-1,j}}{\Delta x}    & \text{if $D_x(x_i,y_j) = -1$,} \\
+    \frac{f_{i+1,j} - f_{i,j}}{\Delta x}    & \text{if $D_x(x_i,y_j) =  1$,} \\
+    \frac{f_{i+1,j} - f_{i-1,j}}{2\Delta x} & \text{if $D_x(x_i,y_j) =  0$,}
+  \end{cases}
+  \label{eq:Ddifference}
+\end{equation}
+and similarly for $\partial_y f_{i,j}$, where $f_{i,j}$ is a piecewise smooth
+function.  The DDS is equivalent to using central differences in smooth areas
+and one-sided differences in areas close to the kinks.
+
+\subsection{Curve-fitting discretization method}
+\label{sec:curvature-curve-fitting}
+The curve-fitting discretization method (CFDM) was first presented
+in~\cite{Lervag11} and is based on the method by \citet{Macklin06}.  The main
+idea is to identify kink regions with the quality function \eqref{eq:quality},
+and to use a curve parametrisation of the closest interface to calculate the
+curvature in regions where the quality function is larger than the threshold
+parameter, $\eta$.
+
+The CFDM applied to the curvature or the normal vector at the grid point $\vct
+x_{i,j}$ can be summarized as follows.  See also \cref{fig:cfdm}, which shows
+an example of the CFDM used at $\vct x_{i,j}$.
+\begin{enumerate}
+  \item If the quality of the level-set function in the neighbourhood of $\vct
+    x_{i,j}$ is good, that is
+    \[
+      Q(\vct{x}_{n,m}) \le \eta \; \forall (n,m) \in [i-1,i+1]\times[j-1,j+1],
+    \]
+    then we use a standard discretization.  Otherwise continue to the next
+    step.
+  \item Locate the closest interface, $\Gamma$.
+  \item Find a set of points on the located interface, $\vct x_1, \dots, \vct
+    x_n \in \Gamma$.
+  \item Create a parametrisation $\vct \gamma(s)$ of the points $\vct x_1,
+    \dots, \vct x_n$.
+  \item Use the parametrisation $\vct \gamma(s)$ to calculate a local level-set
+    function.
+  \item Use a standard discretization of the local level-set function to
+    calculate the curvature or the normal vector.
+\end{enumerate}

+\subsection{Local level-set extraction method}
+\label{sec:lolex}
+The local level-set extraction (LOLEX) method is based on the method presented
+by \citet{Salac08}, here called the SLM.  It was found that the latter method
+was insufficient, because it did not treat all the kink problems.  The LOLEX
+method is therefore a further development of the SLM, in that it handles the
+kink regions in a more general manner.
+
+The LOLEX method applied to the curvature or the normal vector at a grid point
+$\vct x_{i,j}$ is summarized by the following algorithm.  The algorithm is
+presented with 2D notation for clarity, and extends easily to 3D.  See also
+\cref{fig:lolex}, which gives a simple example of the procedure.
+\begin{enumerate}
+  \item If the quality in the neighbourhood of $\vct x_{i,j}$ is good, that is
+    \[
+      Q(\vct{x}_{n,m}) \le \eta \; \forall (n,m) \in [i-1,i+1]\times[j-1,j+1],
+    \]
+    then we use a standard discretization.  Otherwise continue to the next
+    step.
+  \item Copy a small, local square centred around $\vct x_{i,j}$ from the
+    level-set function $\varphi$ into a local array $\varphi_\text{loc}$.
+  \item Identify and enumerate all the \emph{bodies} in the local array
+    $\varphi_\text{loc}$.  A \emph{body} is here defined as a set of
+    neighbouring points where $\varphi_\text{loc}<0$, see \cref{fig:lolex}.
+    There will be $n\geq 0$ bodies in any given $\varphi_\text{loc}$ array.
+  \item If no body is identified, that is, if $n=0$, then use a standard
+    discretization with the global level-set function $\varphi$.  Otherwise
+    continue to the next step.
+  \item For each body $n$, extract the relevant parts of $\varphi_\text{loc}$
+    into an array $\varphi_\text{loc}^n$.  If necessary, extrapolate values to
+    ghost cells.
+  \item For each body, $n$, reinitialize $\varphi_\text{loc}^n$.
+  \item At this step, all the bodies in the local grid have their own
+    local level-set functions that have been reinitialized to proper
+    signed-distance functions.  Due to the separation of the bodies, there
+    are no longer any kinks.
+  \item Use the standard discretization of the curvature and the normal
+    vector at the local level-set function that represents the body that is
+    closest to $\vct x_{i,j}$.

+\chapter{The diffuse-domain approach}
+\label{chap:diffuse-domain}
+In the previous chapters, we have considered the modelling of two-phase flows,
+and in particular methods for calculating the curvature and normal vector with
+the level-set method in a reliable manner.  In this chapter, we consider
+a different problem of a more general nature:  How to solve partial
+differential equations (PDEs) in complex domains.  In particular, we consider
+an extension of a diffuse-domain method (DDM) by a high-order correction term
+that gives increased accuracy with respect to interface-width refinements.
+
+We begin with a short introduction to the diffuse-domain approach.  We then
+outline how it can be used to derive a DDM for the steady reaction-diffusion
+equation with Neumann boundary conditions.  Next, we continue with a brief
+introduction to the method of matched asymptotic expansions.  Finally, we
+introduce the high-order correction term derived in Paper~E and show that the
+resulting DDM converge with second order in the diffuse-interface width to the
+original problem.  The analysis also shows that the correction term is not
+necessary for second-order convergence.
+
+\section{Introduction}
+There exist several methods for solving PDEs in complex domains.  Most of them
+have in common that they require tools or methods that are not frequently
+available in standard finite-element or finite-difference software packages.
+Examples of such methods include the immersed-interface method
+\cite{LeVeque94}, the matched interface and boundary method \cite{Zhou06}, the
+extended and composite finite-element method \cite{Dolbow09}, embedded boundary
+methods \cite{Johansen98}, cut-cell methods \cite{Ji06}, and ghost-fluid
+methods \cite{Fedkiw99}.  A different approach, known as the fictitious domain
+method~\cite{Glowinski94,Glowinski96} or the domain imbedding
+method~\cite{Buzbee71}, either augments the original system with equations for
+Lagrange multipliers to enforce the boundary conditions, or use the penalty
+method to enforce the boundary conditions weakly.  For a more complete list of
+references, see Paper~E.
+
+The DDM is an alternative method for solving PDEs in complex domains.  The main
+idea is to use an implicit representation of the boundary, where the sharp
+boundary is replaced by a diffuse layer.  The PDEs are then reformulated on
+a larger, regular domain, and the boundary conditions are incorporated via
+source terms in the diffuse layer.  When the thickness of the diffuse layer is
+reduced, these source terms tend towards singular source terms.  The resulting
+PDEs can then be solved with the use of standard tools and methods.
+
+The diffuse-domain approach was first introduced by \citet{Kockelkoren03} to
+study diffusion inside a cell with homogeneous Neumann boundary conditions at
+the cell boundary.  It was later used by \citet{Li09} to develop a DDM for
+solving PDEs in complex evolving domains with Dirichlet, Neumann and Robin
+boundary conditions, which is hereafter called the DDM1.  The DDM1 has been
+used by \citet{Teigen09-b}, who modelled bulk-surface coupling of material
+quantities on a deformable interface.  It was also used by \citet{Aland10} to
+simulate incompressible two-phase flows in complex domains in 2D and 3D, and by
+\citet{Teigen11} to study two-phase flows with soluble surfactants.
+
+An analysis of the error behaviour of the diffuse-domain approach was done by
+\citet{Franz12} for a diffuse-domain approximation of an elliptic problem with
+Dirichlet boundary conditions.  They considered the infinity norm of the
+difference of the approximated solution and the exact solution, and their
+analysis shows that the approximation quality is of order one in the interface
+width.
+
+In Paper~E, we present the DDM2, which is an extension of the DDM1 by
+a high-order correction term.  The DDM2 is derived for elliptic problems with
+Neumann and Robin boundary conditions, and it is shown to be asymptotically
+second-order accurate in the interface width.  However, the analysis in Paper~E
+is somewhat lacking in that it assumes that the DDM1 is only first-order
+accurate.  In the following sections, we extend the analysis of Paper~E and
+show that the DDM1 is also second-order accurate.  The analysis is shown for
+the steady reaction-diffusion equation with Neumann boundary conditions, but
+the same technique also applies for the corresponding Robin problem.
+
+\section{The DDM for a Neumann problem}
+Consider the steady reaction-diffusion equation with Neumann boundary
+conditions,
+\begin{equation}
+  \begin{alignedat}{2}
+    \lapl u - u  &= f        & \txin D, \\
+    \ndot\grad u &= g \qquad & \txon \partial D,
+  \end{alignedat}
+  \label{eq:ddan}
+\end{equation}
+where $f$ and $g$ are given.  Let $\chi_D$ be the characteristic function of
+$D$,
+\begin{equation}
+  \chi_D = \begin{cases}
+    1 & \text{if $x\in D$,} \\
+    0 & \text{if $x\notin D$.}
+  \end{cases}
+\end{equation}
+The main idea with the diffuse-domain approach is to extend the original
+equation \eqref{eq:ddan} into a larger and regular domain $\Omega\supset D$, as
+depicted in \cref{fig:ddadomain}.  The extension can be written as
+\begin{equation}
+  \div(\chi_D\grad u) - \chi_D u + \text{BC} = \chi_D f,
+  \label{eq:ddm}
+\end{equation}
+where BC is a singular source term that represents the physical boundary
+condition on $\partial\Omega$.

+
+The characteristic function is typically approximated by the phase-field
+function,
+\begin{equation}
+  \chi_D \simeq \phi(\vct x,t) = \frac{1}{2} \left( 1
+  - \tanh \left( \frac{3r(\vct x,t)}{\epsilon} \right) \right),
+  \label{eq:characteristic}
+\end{equation}
+where $\epsilon$ is the interface width and $r(\vct x,t)$ is the
+signed-distance function with respect to the boundary $\partial D$, which is
+taken to be negative inside $D$.
+
+The main difficulty with the diffuse-domain approach is the derivation of
+approximations for the boundary condition term BC.  \citet{Li09} give four
+approximations that are shown to converge asymptotically with first order in
+$\epsilon$ to the original equation when $\epsilon$ is decreased.  In the
+following we consider the approximation
+\begin{equation}
+  \text{BC} \simeq |\grad\phi| g.
+  \label{eq:bc1}
+\end{equation}
+If we combine the above approximations \eqref{eq:characteristic} and
+\eqref{eq:bc1}, we get a DDM1 equation for \eqref{eq:ddan},
+\begin{equation}
+  \div\left(\phi\grad u\right) - \phi u +  |\grad\phi| g = \phi f.
+  \label{eq:ddm1}
+\end{equation}

+\section{The method of matched asymptotic expansions}
+The following is a brief introduction to the method of matched asymptotic
+expansions, which is used to show that a given diffuse-domain approximation
+converges to the original problem when the interface width is decreased.  More
+details can be found in Paper~E and in \cite{Pego88}.
+
+Let $u$ be some diffuse-domain variable.  The asymptotic convergence of a given
+diffuse-domain approximation can be shown through expansions of the
+diffuse-domain variables in powers of the interface thickness $\epsilon$ in
+regions close to and far from the interface.  For example, the expansions of
+$u$ are
+\begin{align}
+  u(\vct x)        &= \sum_{k=0}^\infty \epsilon^k      u^{(k)}(\vct x), \\
+  \hat u(z,\vct s) &= \sum_{k=0}^\infty \epsilon^k \hat u^{(k)}(z,\vct s),
+\end{align}
+where $u(\vct x)$ and $\hat u(\vct s,z)$ denote the outer and inner expansions,
+respectively.  Here $z$ is a stretched variable,
+\begin{equation}
+  z = \frac{r(\vct x)}{\epsilon},
+\end{equation}
+where $r$ is the signed distance from the point $\vct x$ to $\partial D$ and is
+taken to be negative inside $D$.  Further, $z$ and $\vct s$ form a local
+coordinate system such that
+\begin{equation}
+  \vct x(\vct s,z) = \vct X(\vct s) + \epsilon z\vct n(\vct s),
+\end{equation}
+where $\vct X(\vct s)$ is a parametrisation of the interface, $\vct n(\vct s)$
+is the interface normal vector, and $z$ is a stretched variable.
+
+When the inner and outer expansions are found, they are matched in a region
+where both solutions are valid and where $\epsilon z = \bigo 1$, see
+\cref{fig:regions}.  The outer solution is then evaluated in the inner
+coordinates, which leads to a set of matching conditions that must hold when
+$\epsilon\to 0$.  If we consider $\epsilon$ to be fixed and let $z \to
+\pm\infty$, we get the following asymptotic matching conditions:
+\begin{equation}
+  \label{eq:match1}
+  \zlimpm \hat u^{(0)}(z,\vct s) = u^{(0)}(\vct s),
+\end{equation}
+and as $z \to \pm\infty$,
+\begin{align}
+  \label{eq:match2}
+  \hat u^{(1)}(z,\vct s) &= u^{(1)}(\vct s)
+    + z\ndot\grad u^{(0)}(\vct s) + \smallo 1, \\
+  \begin{split}
+    \hat u^{(2)}(z,\vct s) &= u^{(2)}(\vct s)
+      + z\ndot\grad u^{(1)}(\vct s) \\
+      &\quad + \frac{z^2}{2} (\ndot\grad)\grad u^{(0)}(\vct s)\cdot\vct n
+      + \smallo 1.
+    \label{eq:match3}
+  \end{split}

+\end{figure}
+
+We remark that the inner expansion is used to obtain the boundary condition on
+$\partial D$, and that the outer solution is used to obtain the sharp-interface
+equation inside the physical domain $D$.
+
+To show that a given DDM approximation converges with second order, one must
+show that the order-one term of the outer solution of the DDM equation is zero
+in $D$.  As an example, we consider the outer solution of the DDM1 equation
+\eqref{eq:ddm1}, which is
+\begin{equation}
+  \begin{split}
+    \lapl u^{(0)} - u^{(0)} &= f, \\
+    \lapl u^{(1)} - u^{(1)} &= 0, \\
+    \lapl u^{(k)} - u^{(k)} &= 0,\qquad k = 2,3,\dots.
+  \end{split}
+  \label{eq:ddm_outer}
+\end{equation}
+For the solution to be asymptotically second order, that is $u = u^{(0)}
++ \bigo{\epsilon^2}$, we must have that $u^{(0)}$ satisfies the original
+problem \eqref{eq:ddan} and that $u^{(1)}=0$.  Thus the inner expansion must
+yield a boundary condition for $u^{(1)}$ to enforce $u^{(1)}=0$.
+
+\section{Asymptotic analysis of the DDM1 and the DDM2}
+\label{sec:DDM2}
+In Paper~E we present the DDM2, which extends the DDM1 \eqref{eq:ddm1} with
+a high-order correction term,
+\begin{equation}
+  \div\left(\phi\grad u\right) - \phi u +  |\grad\phi| g
+    + r|\grad\phi|\left(f - \kappa  g - \lapls u + u\right) = \phi f.
+  \label{eq:ddm2}
+\end{equation}
+Here $r|\grad\phi|\left(f - \kappa  g - \lapls u + u\right)$ is the
+correction term, $\kappa$ is the curvature of the boundary $\partial D$, and
+$\lapls u$ is the surface Laplacian of $u$, which can be defined as
+\begin{equation}
+  \lapls u \equiv
+  \left( I - \vct n\otimes\vct n \right)
+        \div \left( I - \vct n\otimes\vct n \right)\grad u,
+\end{equation}
+where $I$ is the identity matrix and $\vct n$ is the normal vector.  The
+curvature can be calculated from the phase-field function
+\eqref{eq:characteristic} as
+\begin{equation}
+  \kappa = -\div\frac{\grad\phi}{|\grad\phi|}.
+\end{equation}
+
+In the following, we use the method of matched asymptotic expansions to show
+that the DDM1 \eqref{eq:ddm1} and the DDM2 \eqref{eq:ddm2} are both
+second-order approximations of \eqref{eq:ddan} in $\epsilon$.  First, it is
+easy to see that the outer expansions of both approximations are given by
+\eqref{eq:ddm_outer}.
+
+Next, we consider the inner expansion of the DDM2 \eqref{eq:ddm2}, which is
+\begin{multline}
+  \frac{1}{\epsilon^2}\left(\phi\hat u_z\right)_z
+  + \frac \kappa \epsilon \phi\hat u_z
+  + \phi\lapls \hat u
+  - \phi\hat u \\
+  - \frac 1 \epsilon \phi_z g
+  - z\phi_z\left(\hat u + \hat f - \kappa g - \lapls\hat u\right)
+  = \phi \hat f.
+  \label{eq:ddm_inner}
+\end{multline}
+We expand $\hat u(z,\vct s)$ in powers of $\epsilon$ and collect the lowest
+order terms,
+\begin{equation}
+  \left(\phi\hat u_z^{(0)}\right)_z = 0.
+\end{equation}
+If we integrate over all $z$, we get that $\hat u_z^{(0)} = 0$.  The next order
+terms of~\eqref{eq:ddm_inner} then give
+\begin{equation}
+  \left(\phi\hat u_z^{(1)}\right)_z = \phi_z g,
+\end{equation}
+and again we integrate, which gives that
+\begin{equation}
+  \phi\hat u_z^{(1)} = \phi g + C
+  \label{eq:uz1}
+\end{equation}
+where the constant $C$ must be zero, since $\lim_{z\to\infty}\phi(z) = 0$.  Now
+consider the limit $z\to-\infty$ and use the matching condition
+\eqref{eq:match2} to get
+\begin{equation}
+  \ndot\grad u^{(0)} = g.
+\end{equation}
+Thus $u^{(0)}$ satisfies the original problem at least to first order in
+$\epsilon$.  This shows that both DDM1 and DDM2 are first-order approximations
+of the sharp-interface problem.
+
+To obtain the result for the next order, we need to apply the derivative of
+the matching condition \eqref{eq:match3},
+\begin{equation}
+  \hat u_z^{(2)} = \ndot\grad u^{(1)}
+      + z (\ndot\grad)\grad u^{(0)}\cdot\vct n.
+  \label{eq:match3_z}
+\end{equation}
+Further, we use that $u^{(0)}$ satisfies
+\begin{equation}
+  \lapl u^{(0)} - u^{(0)} = f^{(0)},
+\end{equation}
+and that the Laplacian may be decomposed as
+\begin{equation}
+  \lapl u = (\ndot\grad)\grad u\cdot\vct n + \kappa\ndot\grad u + \lapls u,
+\end{equation}
+to get
+\begin{equation}
+  (\ndot\grad)\grad u^{(0)}\cdot\vct n
+    = u^{(0)} + f^{(0)} - \kappa g - \lapls u^{(0)}.
+  \label{eq:ngradun}
+\end{equation}
+Now insert \eqref{eq:ngradun} into \eqref{eq:match3_z} and use the matching
+condition \eqref{eq:match1} to obtain a modified matching condition,
+\begin{equation}
+  \hat u_z^{(2)} - z\left(\hat u^{(0)} + \hat f^{(0)}
+        - \kappa g - \lapls \hat u^{(0)}\right)
+  = \ndot\grad u^{(1)}.
+  \label{eq:match3_z2}
+\end{equation}
+
+We are now ready to consider the zeroth order terms,
+\begin{multline}
+  \label{eq:o1}
+  \left(\phi\hat u^{(2)}_z\right)_z
+  + \phi\kappa\hat u_z^{(1)}
+  + \phi\lapls \hat u^{(0)}
+  - \phi\hat u^{(0)} \\
+  - z\phi_z\left(\hat u^{(0)}
+      + \hat f^{(0)} - \kappa g - \lapls\hat u^{(0)}\right)
+  = \phi \hat f^{(0)}.
+\end{multline}
+The modified matching condition \eqref{eq:match3_z2} motivates that we subtract
+and add the term
+\[
+  \bigg(z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\bigg)_z
+\]
+to \eqref{eq:o1}, which gives
+\begin{multline}
+  \bigg(\phi\hat u_z^{(2)}
+    - z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\bigg)_z \\
+  + \bigg(z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\bigg)_z \\
+  + \phi\kappa\hat u_z^{(1)}
+  + \phi\lapls \hat u^{(0)}
+  - \phi\hat u^{(0)} \\
+  - z\phi_z\left(\hat u^{(0)}
+      + \hat f^{(0)} - \kappa g - \lapls\hat u^{(0)}\right)
+  = \phi \hat f^{(0)}.
+\end{multline}
+We expand the terms and use \eqref{eq:uz1},
+\begin{multline}
+  \bigg(\phi\hat u_z^{(2)}
+    - z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\bigg)_z \\
+  + \cancel{\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)} \\
+  + z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)_z \\
+  + \cancel{\phi\kappa g
+  + \phi\lapls \hat u^{(0)}
+  - \phi\hat u^{(0)}}
+  = \cancel{\phi \hat f^{(0)}},
+  \label{eq:o2}
+\end{multline}
+or
+\begin{multline}
+  \bigg(\phi\hat u_z^{(2)}
+    - z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\bigg)_z \\
+  + z\phi\left(\cancel{\hat u_z^{(0)}} + \hat f_z^{(0)}
+      - \cancel{(\kappa g)_z}
+      - \cancel{\lapls \hat u_z^{(0)}}\right) = 0.
+\end{multline}
+If we assume that $\hat f_z^{(0)}$, we get
+\begin{equation}
+  \bigg(\phi\hat u_z^{(2)}
+    - z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\bigg)_z = 0.
+  \label{eq:o3}
+\end{equation}
+Finally, we integrate the left-hand side and take the limit,
+\begin{align}
+  \nonumber
+  \eint{\bigg(\phi\hat u_z^{(2)}
+    &- z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+     - \lapls \hat u^{(0)}\right)\bigg)_z} \\
+  \nonumber
+  &= \ejmp{\phi\hat u_z^{(2)}
+    - z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)} \\
+  \nonumber
+  &= -\zlimm{\left(\hat u_z^{(2)}
+    - z\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\right)} \\
+  &= -\ndot\grad u^{(1)},
+\end{align}
+thus
+\begin{equation}
+  \ndot\grad u^{(1)} = 0.
+  \label{eq:ngradu1}
+\end{equation}
+Combined with \eqref{eq:ddm_outer}, this shows that $u^{(1)}=0$, and so DDM2
+converges asymptotically with second order to the original problem.
+
+The analysis above also holds for DDM1, except instead of \eqref{eq:o3} we get
+\begin{multline}
+  \bigg(\phi\hat u_z^{(2)}
+    - z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\bigg)_z \\
+  = - z\phi_z \left(\hat u^{(0)} + \hat
+        f^{(0)} - \kappa g - \lapls \hat u^{(0)}\right)
+  = - z\phi_z D,
+  \label{eq:o4}
+\end{multline}
+where $D$ is independent of $z$.  Now we use that
+\begin{equation}
+  \phi_z = -(3 \sech^2 3z)/2,
+\end{equation}
+which follows from the definition of the phase-field function
+\eqref{eq:characteristic}.  We integrate the right-hand side, which gives
+\begin{equation}
+  D\eint{z\phi_z} = -D\frac 3 2\eint{z\sech^2 3z} = 0.
+\end{equation}
+Thus DDM1 is also second order in $\epsilon$.
+
+The difference between the DDM1 and the DDM2 is therefore that the correction
+term with the DDM2 directly cancels the term on the right-hand side in
+\eqref{eq:o4}.  This should give an increase of accuracy, but the convergence
+order remains the same.
+
+The analysis for the corresponding Robin problem is essentially the same as the
+above.  In Paper~E, the DDM1 and DDM2 are compared for several elliptic
+problems with both Neumann and Robin boundary conditions.  The results of
+Paper~E show that the correction term in the DDM2 leads to an increase of
+accuracy and that both DDM1 and DDM2 converge with second-order accuracy.
+
+\section{Summary}
+In this chapter, we have given a brief introduction to the diffuse-domain
+method (DDM).  We considered a steady reaction-diffusion equation with Neumann
+boundary conditions \eqref{eq:ddan} and two DDM approximations:  DDM1
+\eqref{eq:ddm1} and DDM2 \eqref{eq:ddm2}.  The DDM2 is an extension of DDM1 by
+a high-order correction term, and was first derived in Paper~E.
+
+Next, we gave an outline of the method of matched asymptotic expansions, and we
+used it to show that both the DDM1 and the DDM2 converged asymptotically with
+second order in the diffuse-interface width to the original equation
+\eqref{eq:ddan}.  The analysis shows that the correction term in the DDM2 leads
+to a cancellation in the asymptotic expansions.  By doing the integration, we
+see that this cancellation is not necessary for obtaining the second order
+convergence.

+\section[Paper A]{Paper A:  Calculation of interface curvature with the
+  level-set method}
+Karl Yngve Lervåg.  Published in \emph{MekIT'11 - 6th National Conference on
+  Computational Mechanics, Trondheim}, 2011.  ISBN: 978-82-519-2798-7.
+
+In this paper I address a problem with the calculation of the interface
+curvature with the level-set method, cf.\ \cref{sec:curvature}.  The curvature
+can be calculated from the level-set function, $\phi$, as
+\begin{equation}
+  \kappa = \div\vct n = \div\frac{\grad\phi}{|\grad\phi|}.
+\end{equation}
+It is typically discretized by standard methods such as the second-order
+central-difference scheme (CD-2), and interpolated to the interface where
+needed \cite{Osher88,Kang00,Osher03}.  However, the level-set function as
+a signed-distance function will tend to have kinks where its gradient is
+discontinuous.  The standard methods may lead to large errors in the curvature
+close to these regions, which in turn may lead to errors in the surface tension
+force.
+
+The main contribution of this paper is a new curve-fitting discretization
+method (CFDM) for the curvature (see \cref{sec:curvature-curve-fitting}).  The
+method is based on the approach developed by \citet{Macklin06}.  It differs in
+that it uses a cubic Hermite spline parametrisation of the interface, and that
+the curvature values are calculated on the grid and then interpolated to the
+interface as opposed to using a localised grid centred at the interface as in
+\cite{Macklin06}.

+The CFDM is tested and compared with the CD-2 for two test cases, and it is

+Karl Yngve Lervåg and Åsmund Ervik.  Published in \emph{ENUMATH 2011}
+proceedings volume, Springer, 2013.  ISBN: 978-3642331336.
+
+This paper is a continuation of Paper A.  The main contribution in this paper
+is a comparison of different methods for calculating the curvature in a robust
+manner with the level-set method in the kink regions.  In particular, the
+CFDM\footnote{The method is called LM in the paper.  Here CFDM is used, in
+  order to be consistent with the rest of the thesis.} that was presented in
+Paper A is compared with Macklin and Lowengrub's method (MLM)~\cite{Macklin06}.
+In addition, the method is compared with the second-order central-difference
+scheme (CD-2) and the more recent method presented by \citet{Salac08}, here
+called Salac and Lu's method (SLM).
+
+The main result in the paper is shown in \cref{fig:B1}, which shows
+a comparison of the methods for a case where two drops collide in a 2D shear
+flow.  In particular, it shows snapshots of the evolution of the interfaces and
+the curvature at times $t=\SI{2.30}{s}$, $t=\SI{2.75}{s}$, and
+$t=\SI{3.10}{s}$.  The results show that all of the improved methods, that is
+MLM, CFDM, and SLM, handle the kink region in a more reliable manner than CD-2.
+The reason that the result with MLM differs from those with CFDM and SLM might
+be that it uses a localised grid centred at the interface to calculate the
+curvature, which means that it does not need to use interpolation of the
+curvature from the grid to the interface.  Note that the difference is mainly
+that the MLM results in slightly earlier coalescence in the given case.

+\section[Paper C]{Paper C:  Calculation of the interface curvature and normal
+  vector with the level-set method}
+Karl Yngve Lervåg, Bernhard Müller, and Svend Tollak Munkejord.  Published in
+Computers and Fluids, volume 84 (2013), 218--230.
+
+Paper A presented the curve-fitting discretization method (CFDM) for the
+calculation of the curvature with the level-set method.  The method was
+designed to be robust in the calculation of the curvature in kink regions, that
+is regions where the gradient of the level-set function is not smooth.  This
+paper presents the details of the CFDM and applies it to the calculation of
+both the curvature and the normal vector.
+
+In the paper we compare the CFDM with the second-order central-difference
+scheme (CD-2) for several test cases.  In the first case, we consider the
+curvature calculations for a nontrivial geometry that includes some kink
+regions.  This is a static test case with no flow, and the results show that
+the CD-2 leads to large errors for the curvature calculations in areas close to
+kink regions and that these errors are not present with the CFDM.
+
+In the following two cases, we consider the collision of two drops in a 2D
+shear flow and in an axisymmetric flow.  These cases show that the errors in
+the curvature calculations in the kink regions with the CD-2 lead to errors in
+the pressure that prevents coalescence.  These errors are prevented with the
+CFDM.  The curvature and the evolution of the interfaces for the axisymmetric
+case are shown in \cref{fig:C1,fig:C2}.  As in the earlier results of Papers
+A and B, the figures show that the errors in the curvature calculation with
+CD-2 prevent coalescence, in this case leading to a slower coalescence process.

+\section[Paper D]{Paper D:  A robust method for calculating interface curvature
+  and normal vectors using an extracted local level set}
+Åsmund Ervik, Karl Yngve Lervåg, and Svend Tollak Munkejord.  Submitted to
+Journal of Computational Physics, 2013.
+
+In this paper we present an alternative method for the calculation of the
+curvature and the normal vector of an interface with the level-set method in
+kink regions, hereafter called the local level-set extraction (LOLEX) method.
+The method is based on a method presented by \citet{Salac08} (SLM), who handle
+the kink region by extracting different bodies of a domain into separate
+level-set functions.  This procedure removes most of the kink regions, but it
+does not handle kink regions that are due to complex interfaces of single
+bodies.  Our method extends the SLM by making it local.  That is, we only
+consider the local area around the point for which we are calculating the
+curvature or the normal vector.  This leads to a method that is more generally
+applicable, as shown in \cref{fig:D1}.  The figure shows a comparison between
+the LOLEX method, the SLM, and the standard central differences (CD-2).  CD-2
+leads to curvature spikes at the kink regions, as explained in
+\cref{sec:curvature}.  The SLM gives a better result for the kink regions
+around the rightmost disc.  However, since the other two discs are connected to
+each other and to the film, they are considered to be the same body and are
+extracted into the same level-set function.  Several kink regions are therefore
+not removed.  Since the LOLEX method only considers the local area, as
+explained in \cref{sec:lolex}, it is able to handle all the kink regions in
+a robust manner.

+    negative and red is positive.}
+  \label{fig:D1}
+\end{figure}
+
+The LOLEX method has proven to be a good alternative to the CFDM presented in
+Paper A.  Its main advantages are that it does not rely on complex algorithms
+as used in the CFDM or by \citet{Macklin06}, and that the method easily extends
+to 3D as demonstrated in the paper in Section~4.4.
+
+In the previous papers A--C, we used the DP1 projection method by
+\citet{Hansen05}.  In this paper we instead used the more standard Chorin
+projection method.  These methods differ in that the DP1 assumes
+\begin{equation}
+  \div\left(\pdt{\vct u}\right) = 0.
+\end{equation}
+When compared with the Chorin method, this assumption becomes equivalent to
+assuming that $\div\vct u^{n} = 0$ in \eqref{eq:PoissonChorin}.  That is, the
+DP1 assumes that the initial velocity field is divergence free.  We have found
+that the DP1 works well in most cases, but that it is less robust than the
+Chorin method.  In particular, the Chorin method is not equally affected by
+errors in the curvature calculations in kink regions.  In other words, the
+difference between using a standard discretization and an improved
+discretization of the curvature is smaller with the Chorin method than with the
+DP1.
+
+The LOLEX method is used for several test cases and compared with CD-2.  The
+results indicate that even though we use the Chorin projection method, the
+LOLEX method outperforms CD-2 in all cases.  Further, the results agree well
+with experiments, except for time instants, as shown in \cref{fig:D2}.  The
+exact reason why the time instants do not match is not known, but one reason
+may be that the initial condition of the numerical simulation did not match the
+corresponding state of the experiment.

+When we study the drop-film collision processes, an important consequence of
+the error in the curvature calculation is a loss of kinetic energy.  This can
+be seen in \cref{fig:D3}, which compares the LOLEX method with CD-2 at two
+different stages of the collision process.  The figure also compares two
+different frequencies of reinitialization of the level-set function:  Every
+7 time steps ((a) and (c)) and every single time step ((b) and (d)).  The
+figure shows that the error in the curvature calculation with CD-2 leads to
+a shorter neck, as seen in \cref{fig:D3}, (c) and (d).  The error is larger for
+the higher frequency of reinitialization.  The results indicate that CD-2 leads
+to a loss of kinetic energy during the collision process when compared with the
+LOLEX method.  The LOLEX method is not significantly affected by the amount of
+reinitialization, and the kink region does not affect the curvature
+calculation, cf.\ \cref{sec:lolex}.  Thus the pressure field is more sensible,
+as seen in \cref{fig:D3} (a) and (b).  Finally, we remark that some authors
+have noted \cite{Blanchette06} that the height of the neck and the dynamics of
+the capillary waves are important factors for the partial coalescence
+mechanism, which implies that the correct calculation of the curvature is
+important to capture the correct physical behavior.

+\section[Paper E]{Paper E:  Towards a second-order diffuse-domain approach for
+  solving PDEs in complex geometries}
+Karl Yngve Lervåg and John Lowengrub.  Submitted to Communications in Math.
+Sciences, 2013.
+
+\citet{Li09} developed a diffuse-domain method for solving partial-differential
+equations (PDEs) inside complex, dynamic geometries with Dirichlet, Neumann,
+and Robin boundary conditions.  This method is in the following referred to as
+DDM1.  They use the diffuse-domain approach~\cite{Kockelkoren03}, where the
+geometry is represented implicitly and the sharp boundary is replaced by
+a diffuse layer with a fixed interface width.  The original governing equations
+are then reformulated on a larger, regular domain and the boundary conditions
+are incorporated via singular source terms.  The method of matched asymptotic
+expansions is used to show that the reformulated problem converges
+asymptotically to the original problem.
+
+In the present paper, we use the method of matched asymptotic expansions to
+extend the DDM1 with include a high-order correction term in the diffuse
+formulation, cf.\ \cref{sec:DDM2}.  The extension is derived for elliptic
+problems with Neumann and Robin boundary conditions, where the correction term
+is shown to yield an asymptotically second-order accurate approximation of the
+original problem.  The new method is referred to as the DDM2.
+
+The DDM1 and DDM2 are compared for a selection of test problems.  The resulting
+equations were discretized by standard second-order central-difference schemes
+on uniform grids, and solved by a multigrid method.  A red-black Gauss-Seidel
+type iterative method was used as a smoother, see \cite{Wise07}.
+
+In addition to the comparison of DDM1 and DDM2, we compared two different
+approximations of the boundary conditions.  These correspond to different
+diffuse-interface surface delta functions, and for the Neumann boundary
+conditions they are
+\begin{equation}
+  \text{BC1} = |\grad\phi| g,
+\end{equation}
+and
+\begin{equation}
+  \text{BC2} = \epsilon|\grad\phi|^2 g.
+\end{equation}
+The approximations are similar for the Robin boundary condition, although here
+it was found that only BC1 resulted in a valid asymptotically second-order
+accurate DDM2.
+
+Our results show that the global accuracy and convergence of DDM2 is better
+than DDM1, however both methods perform well and the global convergence rate is
+around two for each.  The error was measured as the L$_2$ norm of the
+difference between an analytic solution and the solution $u_\epsilon$ for
+a given interface width, $\epsilon$.
+
+\Cref{fig:E1,fig:E2} show two of the results, the first one with the Neumann
+boundary conditions and the second with the Robin boundary condition.  The
+results indicate that DDM2 performs slightly better than DDM1.  They also show
+that the approximation BC1 gives more accurate results than BC2.  In
+particular, we found that with BC2 we needed much finer grids to obtain
+convergence for a given $\epsilon$.  For the smallest values of $\epsilon$ we
+were not able to refine the grids enough to obtain valid results.

+\chapter{Conclusions and outlook}
+\label{chap:conclusions}
+This thesis has considered two different problems:  The discretization of
+interface curvature and normal vectors with the level-set method and
+a diffuse-domain approach for solving partial-differential equations (PDEs) in
+complex domains.  In the following, some general concluding remarks and
+recommendations for further work are given.
+
+\section*{Conclusions}
+The first part of the thesis considered the modelling of incompressible
+two-phase flow.  The main motivation was to study two-phase flow phenomena that
+are relevant for compact heat exchangers, such as drop-drop and drop-film
+collisions.  In particular, the thesis addressed a challenge with the
+calculation of interface curvature and normal vectors with the level-set
+method.  Two methods were presented to handle the discretization in the kink
+regions: A curve-fitting discretization method (CFDM) and a local level-set
+extraction (LOLEX) method.  Both methods were shown to be robust in the kink
+regions, where the standard central-difference scheme (CD-2) fails.  Of these
+methods, the LOLEX method is the preferred method, because it relies on a less
+complicated algorithm that easily extends to 3D.
+
+CD-2 and the LOLEX method were used for simulations of drop-film collisions
+that were compared with experiments.  The results showed that CD-2 leads to
+errors in the curvature that cause unphysical pressure spikes during the
+coalescence.  The errors are shown to lead to a dissipation of kinetic energy
+during the collision and to a slower coalescence process.  The LOLEX method was
+shown to prevent these unphysical pressure spikes, and to produce to more
+accurate results.
+
+The second part of the thesis considered the diffuse-domain approach for
+solving PDEs in complex domains.  The main contribution, presented in Paper~E,
+was the derivation of an asymptotically second-order diffuse-domain method
+(DDM2) for solving elliptic problems in complex geometries with Neumann and
+Robin boundary conditions.  The new method is an extension by a high-order
+correction term of the method presented in \cite{Li09}, here called DDM1.  The
+DDM1 and DDM2 were compared, and the results indicated that the DDM2 was
+slightly better than the DDM1.
+
+The thesis has expanded on the results of Paper~E with a new asymptotic
+analysis that shows that DDM1 is in fact also asymptotically second order.
+This analysis helps to explain why the performance of DDM2 presented in Paper~E
+is only slightly better than that of DDM1.  As such, the new analysis leads to
+a better understanding of the DDM1 and the DDM2.
+
+\section*{Outlook}
+The following gives an outline of some possibilities for future work.
+\begin{itemize}
+  \item A natural continuation of this work is to perform more in-depth
+    comparisons of simulations with experiments for the drop-film collision
+    phenomenon that was started in Paper~D.  In addition, it would be
+    interesting to study other two-phase flow phenomena that are relevant for
+    heat-exchanger processes, for instance drop-drop collisions or flow across
+    tube bundles.  The latter requires the treatment of more complex boundaries,
+    which can be handled either with the diffuse-domain method or other methods
+    from the literature.
+  \item Paper~C gave a short comparison of the standard discretization method
+    (CD-2), the direction-difference scheme (DDS), and the curve-fitting
+    discretization scheme (CFDM) applied to the calculation of the normal
+    vectors.  The results showed that the CD-2 leads to inaccurate results in
+    the kink regions.  The DDS gives robust and accurate results in most cases,
+    but an example is given where only the CFDM yields an accurate result.
+    However, the impact of inaccurate calculations of the normal vector should
+    be investigated in more detail.  The normal vector is used both for the
+    solution of the level-set equations \eqref{eq:ls_adeq},
+    \eqref{eq:ls_velextr}, and \eqref{eq:ls_reinit}, and for the calculation of
+    the interface jumps \eqref{eq:jump_pressure} and \eqref{eq:jumptens}, so
+    one can expect that large errors in the calculation of the normal vector
+    may lead to large errors in the numerical solution.  This warrants
+    a further study.
+  \item Mass and heat transfer are obviously an important part of the
+    heat-exchanger processes.  The models that have been used in this thesis
+    should therefore be expanded with additional models for heat transfer and
+    mass transfer to enable the simulation of more relevant phenomena.
+  \item The DDM2 was only derived for problems with Robin and Neumann boundary
+    conditions.  If possible, it should be extended to also work with Dirichlet
+    boundary conditions.
+  \item As explained in Paper~E, we found that we were unable to solve the
+    discrete system of equations when the surface Laplacian part of the
+    correction term for the DDM2 was included.  A further investigation of this
+    problem should be done, and stable numerical methods to solve the full DDM2
+    equations should be developed.
+  \item The diffuse-domain approach is a promising method for solving problems
+    in complex and confined geometries with standard tools and methods.
+    \citet{Aland10} provide a diffuse-domain formulation of the Navier-Stokes
+    Cahn-Hilliard equations for incompressible two-phase flow and use it to
+    compute two-phase flow in both complex and confined geometries.  However,
+    they do not provide an asymptotic analysis of the reformulated equations to
+    show that the system converges.  Such an analysis would be interesting, in
+    particular to verify that the equations do converge to the original problem
+    when the interface width is decreased.
+  \item Finally, it would be interesting to develop a second-order
+    diffuse-domain formulation for the incompressible Navier-Stokes equations.
+    A starting point would be to use the results and techniques from this
+    thesis and Paper~E.

+\chapter{Introduction}
+This thesis considers the mathematical modelling and numerical computation of
+two-phase flows.  It focuses on developing more robust numerical methods to
+calculate the curvature and the normal vector of the interface between the two
+phases.  In addition it considers a diffuse-domain method for solving partial
+differential equations in complex geometries, and it derives an asymptotically
+second-order method for elliptic problems.
+
+\section{Background and motivation}
+Two-phase flows are particular examples of multiphase flows of gas and liquid
+with an interface that separates the two phases.  In the pedantic sense,
+two-phase flow is flow of a single fluid that occurs as two different phases,
+for example steam and water.  However, it is common to be more general, and in
+this thesis we use the term two-phase flow also for immiscible mixtures of
+different fluids, such as water and oil.
+
+Two-phase flows are crucial to a large amount of processes, both in nature and
+in industry.  Examples range from weather phenomena, such as rain drops falling
+through air, to industrial processes, for instance the separation of water from
+oil.  In general, multiphase flow phenomena influence any process where liquids
+and gases are involved.  In the oil and gas industry, most processes are
+two-phase or multiphase flow processes.  Needless to say, the understanding of
+these phenomena is fundamental in the development of new or improved processes.
+
+Consider the international trade of liquefied natural gas (LNG), which is
+a particular branch of the oil and gas industry that has undergone an
+exceptional growth in the last decades.  There is a strong focus both in Norway
+and internationally on producing LNG on large floaters
+(FLNG)\footnote{FLNG facilities do not yet exist, although a facility is under
+  development by Royal Dutch Shell~\cite{Prelude1}.  The construction of this
+  facility was started in 2012, and the first drilling is stated to commence in
+  2013~\cite{Prelude2}.}.  There are a number of both environmental and
+economic advantages of such FLNG facilities.  In particular, FLNG facilities
+would remove the need of long pipelines from the gas fields to the shore, there
+would be no requirement for compression units to pump the gas to the shore, and
+one would not need to construct onshore production facilities.  This would
+significantly reduce the environmental footprint, and would help preserve
+marine and coastal environments.  Since an FLNG facility can be moved to a new
+location when a field has been depleted, it would make it economically viable
+to open up new business opportunities to develop offshore gas fields that would
+otherwise remain stranded.
+
+Moving the LNG production to an offshore facility presents a demanding set of
+challenges.  A particular challenge is that the elements of a conventional LNG
+facility need to fit into an area roughly one quarter the original size.  Heat
+exchangers are among the main challenges in the design and operation of LNG
+plants \cite{Hesselgreaves01}.  Compact and efficient heat exchangers are
+needed to obtain an energy efficient plant with low emissions.  More optimized
+designs require more accurate tools for design and operation.  Such tools can
+only come as a result of an improved physical understanding of the complex
+two-phase flows occurring in the heat exchangers.  This can be achieved by more
+detailed mathematical modelling, together with dedicated laboratory
+observations, cf.\ \cite{Olsen07}.
+
+\section{Overview of methods for two-phase flow simulations}
+In the following, a brief overview is given of different methods for modelling
+two-phase flows where the interface location is known.  In particular, we focus
+on methods that handle the interface evolution.  For more in-depth reviews, see
+for instance \cite{Cristini04,Scardovelli99,Sethian03}.
+
+Interface propagation methods comprise a range of methods that are often
+categorised as either front tracking or front capturing.  Front-tracking
+methods use Lagrangian particles to track the interface
+explicitly~\cite{Tryggvason01}, while front-capturing methods use an Eulerian
+approach to capture the interface implicitly.  Examples of the latter are
+volume-of-fluid methods~\cite{Scardovelli99,Tryggvason11}, phase-field
+methods~\cite{Anderson98,Jacqmin99,Lowengrub98}, and level-set
+methods~\cite{Osher03}.
+
+The main advantages of front-tracking methods are their inherent accuracy and
+that topological changes do not occur without explicit action.  Hence,
+unphysical numerical reconnection does not occur.  This means that if front
+tracking is used for the simulations of two drops that collide, these drops
+will not coalesce due to numerical reconnection or merging.  However, the
+handling of topological changes are challenging, in particular in three
+dimensions~\cite{Shin02}.  Also, there are some issues of numerical
+instabilities, as discussed by \citet{Sethian85} and \citet{Osher88}.
+
+The volume-of-fluid method utilizes a volume-fraction function whose values
+represent the characteristic function of one of the fluid domains.  Its values
+are zero or one, except in those cells cut by the interface.  A considerable
+advantage of the volume-of-fluid method is that it conserves the mass of both
+fluids well.  However, the reconstruction of the interface from volume
+fractions is not simple, and computation of geometric quantities such as the
+interface curvature is not straightforward.  Also, spurious bubbles and drops
+may be created, cf.\ \cite{Lafaurie94}.
+
+The phase-field methods treat the interface in a diffuse manner, where the
+fluid properties, such as density and viscosity, change rapidly but smoothly
+across the interface.  These methods typically solve the coupled
+Cahn-Hilliard/Navier-Stokes equations, where the Cahn-Hilliard equation is
+based on the free energy of an interface~\cite{Cahn57}.  Through this energy
+formulation, one can model more advanced interface physics such as van der
+Waals interactions, electrostatic forces, and fluids with varying
+miscibilities.  However, the phase-field methods require that one resolves very
+small length scales at the interfaces.  This poses a severe restriction on the
+applicability of phase-field methods for two-phase flow, where the length
+scales of the flow are generally much larger than those of the interface.
+
+In this thesis, we have used the level-set method~\cite{Osher88}, which
+implicitly captures the interface as an isocontour of a function defined in the
+entire domain.  The main motivation of this choice is both that the level-set
+method handles topological changes of evolving interfaces automatically,
+cf.~\citet{Sethian03}, and that it is relatively straightforward to implement.
+
+It should be noted that the automatic handling of topological changes is not
+based on physical principles.  For instance, when two interfaces approach each
+other and their distance becomes less than the spacing of the grid, the
+level-set method can no longer resolve both interfaces and so they are merged.
+An important consequence is that the level-set method does not model the
+physics involved in the coalescence process, and in particular in the smaller
+scales of the film-drainage process.  This process involves a wide range of
+length scales, varying from the nanometer scale where van der Waals force are
+active to the length scales of the external flow.  Some effort has been made to
+include the effects of the smaller scales in front-capturing methods,
+cf.~\cite{Nobari96,Tryggvason10}.  Recently, \citet{Kwakkel13} presented
+a level-set/volume-of-fluid method that is coupled with a film-drainage model
+that predicts if and when two colliding droplets will coalesce.  To prevent the
+numerical coalescence, each droplet has its own locally defined level-set
+function.
+
+The level-set method has been used to model several diverse phenomena,
+such as tumour growth~\cite{Macklin06,Macklin05,Macklin08}, propagation of
+wildland fire~\cite{Mallet09}, and computer RAM production~\cite{Melicher08}.
+For a good and thorough introduction to the level-set method, see
+\cite{Osher03}.
+
+A weakness of the level-set method is that it does not conserve the mass of the
+two fluids, in particular in areas of low resolution and/or high curvature.
+Different approaches have been developed to overcome this disadvantage, for
+example the conservative level-set method~\cite{Olsson05,Olsson07}, the
+particle level-set method~\cite{Enright02}, or the coupled
+level-set/volume-of-fluid method~\cite{Sussman00}.
+
+When we use the level-set method to capture the interface for immiscible and
+incompressible two-phase flow simulations, there will be a sharp change in the
+density and viscosity across the interface.  In this thesis we use the
+ghost-fluid method~\cite{Fedkiw99}, which is a sharp-interface method where the
+jumps are included in the spatial discretizations in a sharp manner.  An
+alternative method is the continuous surface-force method introduced by
+\citet{Brackbill92}, where the density and the viscosity are smeared out across
+the interface through a smoothed Heaviside function.

+\section{Goal and contribution of the present thesis}
+The main goal of the PhD project has been to develop fundamental knowledge of
+two-phase flow phenomenon that are relevant for compact heat exchangers.
+
+In order to do detailed theoretical studies of phenomena that are relevant for
+compact heat exchangers, we need to consider two-phase flows with mass and heat
+transfer in confined and complex geometries.  One such relevant phenomenon is
+the drop-film collision process \cite{Zhao09}.  Even when restricted to
+isothermal and immiscible flows, this simple phenomenon remains a challenge.
+When the level-set method is used to capture the interface, one must be
+particularly careful about how one calculates the interface curvature and
+normal vector.  For instance, when two drops are in near collision there is
+a kink region in the level-set function between the drops, where the gradient
+is discontinuous, see \cref{fig:curvature-problem}.  This discontinuity may
+lead to large errors in the curvature and the normal vector if it is not taken
+into account in the discretization stencils.

+
+As a step towards computing two-phase flow simulations in confined geometries,
+the thesis has considered the diffuse-domain method~\cite{Li09}.  This is
+a method where partial-differential equations in complex domains are extended
+into larger, regular domains with the use of diffuse approximations of the
+physical boundaries.  The approximations converge asymptotically to the
+original problem when the width of the diffuse boundary is reduced.  With this
+method one can use standard numerical methods to solve equations that
+incorporate complex boundaries.
+
+The main contributions of the present thesis are two new methods to calculate
+the curvature and normal vector in a robust manner with the level-set method.
+These methods are shown to yield more accurate calculations of drop-film and
+drop-drop collisions.  The methods are compared with standard methods and with
+other methods from the literature.
+
+In addition, the thesis presents an extension of a diffuse-domain method by
+a high-order correction term for the solution of elliptic problems in complex
+geometries.  New analysis provided in the thesis improves the understanding of
+the diffuse-domain method, and the derived method is shown to be more accurate
+than the existing diffuse-domain method.
+
+\section{Outline of the thesis}
+The thesis is organised as follows: \Cref{chap:two-phase-flow} gives a brief
+overview of the derivation of the governing equations for two-phase flow.  It
+includes a consideration of the fluid-fluid interface conditions and the
+derivation of a simplified jump tensor for the viscous term at the interface.
+
+\Cref{chap:numerical-methods} gives a detailed description of the numerical
+methods that are used to solve the two-phase flow equations.  In particular, it
+describes the level-set method, which is used to capture the interfaces,
+projection methods that are used to solve the Navier-Stokes equations, and the
+spatial and temporal discretization schemes.  At the end of the chapter, an
+overview of the novel discretization methods for the curvature and the normal
+vector is given.
+
+\Cref{chap:diffuse-domain} gives a short introduction to the diffuse-domain
+method for an elliptic problem with Neumann boundary conditions.  It introduces
+the high-order correction term, and shows that the new method converges
+asymptotically with second-order to the original problem.  The chapter presents
+new analysis that shows that the correction term is not necessary for
+second-order convergence.
+
+In \cref{chap:contributions} the main results of the contributed papers A--E
+are summarized, and the author's contributions are highlighted.  Finally,
+\cref{chap:conclusions} gives concluding remarks and provides an outlook for
+future work.
+
+Full-text versions of the research papers A--E are provided in the Appendices

+\chapter{Governing equations for two-phase flow}
+\label{chap:two-phase-flow}
+In this chapter we will give a brief overview of the derivation of the
+governing equations for two-phase flow.  We begin with a consideration of the
+Navier-Stokes equations for single-phase flow.  We then introduce a singular
+surface-force term and derive the Navier-Stokes equations for two-phase flow.
+Finally, we use the Navier-Stokes equations for two-phase flow to derive jump
+conditions at the interface between the phases.
+
+\section{The Navier-Stokes equations for single-phase flow}
+The following is a brief derivation of the Navier-Stokes equations for
+single-phase flows.  For a more thorough derivation of these equations, see for
+instance \citet[§4 and §5]{Aris89} or \citet[Chapter~4]{White03}.
+
+We consider a single-phase, viscous flow in some domain $\Omega$ with boundary
+$\partial\Omega$.  When temperature effects are neglected the flow is described
+by the Cauchy equation
+\begin{equation}
+  \label{eq:cauchy_equation}
+  \rho\left(\cd{\vct u}\right) = \div\tenstr+\rho\vct f,
+\end{equation}
+and the mass conservation equation,
+\begin{equation}
+  \label{eq:cons_of_mass}
+  \pdt\rho + \div(\rho\vct u) = 0.
+\end{equation}
+Here $\rho$ is the fluid density, $\vct u$ is the flow velocity, $t$ is time,
+$\tenstr$ is the stress tensor, $\vct f$ denotes body forces, and $\del$ is
+used to denote the gradient and divergence operators.  The stress tensor for
+Newtonian fluids with zero bulk viscosity is
+\begin{equation}
+  \tenstr = -p\tenI + 2\mu\tenD - \frac 2 3\mu (\trace\tenD) \tenI,
+  \label{eq:viscous_stress_tensor}
+\end{equation}
+where $p$ is the pressure, $\tenI$ is the identity tensor, $\mu$ is the dynamic
+viscosity, and $\trace\tenD$ denotes the trace of the strain-rate tensor
+$\tenD$,
+\begin{equation}
+  \tenD = \frac{1}{2}\left( \grad\vct u + (\grad\vct u)^T \right).
+  \label{eq:deformation_tensor}
+\end{equation}
+For incompressible flow, the mass-conservation equation reduces to
+\begin{equation}
+  \label{eq:navier-stokes-1}
+  \div\vct u = 0,
+\end{equation}
+that is, the velocity field must be divergence free.  If we further assume that
+the viscosity is constant, then it follows that the divergence of the stress
+tensor reduces to
+\begin{equation}
+  \label{eq:stress_tensor}
+  \div\tenstr = -\grad p + \mu\lapl\vct u,
+\end{equation}
+and so the Cauchy equation \eqref{eq:cauchy_equation} becomes
+\begin{equation}
+  \rho\left(\cd{\vct u}\right) = -\grad p + \mu\lapl\vct u + \rho\vct f.
+  \label{eq:navier-stokes-2}
+\end{equation}
+Equations \eqref{eq:navier-stokes-1} and \eqref{eq:navier-stokes-2} are the
+incompressible Navier-Stokes equations for single-phase flow with constant
+viscosity.
+
+\section{The Navier-Stokes equations for two-phase flow}
+We now consider an immiscible two-phase flow of two Newtonian fluids, each with
+its own viscosity and density.  We let $\Omega_1$ and $\Omega_2$ denote the
+domains occupied by fluid 1 and fluid 2, respectively, and let the interface
+between the fluids be denoted by $\Gamma$.  Then $\Omega
+= \Omega_1\cup\Omega_2$ and $\partial\Omega
+= (\partial\Omega_1\cup\partial\Omega_2)\setminus\Gamma$ are the fluid domain
+and its boundary, respectively.  See \cref{fig:domain} for an illustration of
+a two-phase flow domain.

+  \caption{An illustration of a two-phase flow domain.  The interface $\Gamma$
+    separates the two phases $\Omega_1$ and $\Omega_2$.}
+  \label{fig:domain}
+\end{figure}
+
+The extension of the single-phase model to account for two fluids can be made
+by adding a singular surface-force term to represent the effects of surface
+tension between the fluids.  We assume that the surface tension is constant, in
+which case the singular surface force can be defined as
+\begin{equation}
+  \funssf(\vct x,t)
+  = \int_{\Gamma}\sigma\kappa\vct n\delta(\vct x - \vct x_I(\vct s))\dif\vct s,
+  \label{eq:ssf}
+\end{equation}
+where $\sigma$ is the surface tension, $\kappa$ is the local curvature, $\vct
+n$ is the normal vector, $\delta$ is the Dirac delta function, and $\vct
+x_I(\vct s)$ is a parametrisation of the interface.  Thus the Navier-Stokes
+equations for immiscible and incompressible two-phase flow are
+\begin{align}
+  \label{eq:ns1}
+  \div\vct u &= 0, \\
+  \label{eq:ns2}
+  \rho\left(\cd{\vct u}\right) &= -\grad p + \mu\lapl\vct u
+    + \rho\vct f + \funssf.
+\end{align}
+
+\section{Fluid-fluid interface conditions}
+The surface-tension force and the jump in viscosity and density across the
+interface $\Gamma$ lead to a set of interface conditions that must be satisfied
+along the interface $\Gamma$.  The following is a brief derivation of these
+conditions.
+
+First, we only consider flows where there is no mass transfer, which implies
+that
+\begin{equation}
+  \jmp{\vct u}\cdot\vct n = 0,
+\end{equation}
+where $\jmp{\cdot}$ denotes the jump at the interface, for instance $\jmp{\mu}
+= \mu_2 - \mu_1$.  Further, for viscous flows there is no slip at the
+interface, and thus the tangential velocity component of the two fluids must be
+equal at the interface,
+\begin{equation}
+  \jmp{\vct u}\cdot\vct t = 0.
+\end{equation}
+It follows that
+\begin{align}
+  \label{eq:jmpu}
+  \jmp{\vct u} &= 0, \\
+  \label{eq:jmpJut}
+  \jmp{\grad \vct u}\cdot\vct t &= 0.
+\end{align}
+The latter is a direct consequence of the former.  Both fluids are
+incompressible, which gives the trivial identity $\jmp{\div\vct u} = 0$.  If we
+use the identity
+\begin{equation}
+  \div\vct u
+    = \vct n\cdot\grad\vct u\cdot\vct n + \vct t\cdot\grad\vct u\cdot\vct t
+  \label{eq:divuident}
+\end{equation}
+together with \eqref{eq:jmpJut} we get
+\begin{equation}
+  \vct n\cdot\jmp{\grad\vct u}\cdot\vct n = 0,
+  \label{eq:jmpngradun}
+\end{equation}
+which means that the normal component of the normal derivative of the velocity
+field is continuous across the interface.  Note that in \eqref{eq:divuident}
+and in similar expressions in the following, the nabla operator is only applied
+to $\vct u$, not the normal and tangential vectors that follow.

+  \end{tikzpicture}
+  \caption{A sketch of the control volume $\Omega_\epsilon$ that covers the
+    interface, $\Gamma$.}
+  \label{fig:domain_omega_epsilon}
+\end{figure}%
+Next, we consider the conservation of momentum.  We define a control volume
+\begin{equation}
+  \Omega_{\epsilon} = \set{\vct x \in \Omega}{\min_{\vct x_I \in \Gamma}|\vct
+    x - \vct x_I| \leq \epsilon},
+\end{equation}
+where $\epsilon > 0$, see \cref{fig:domain_omega_epsilon}.  We then integrate
+the Cauchy equation \eqref{eq:cauchy_equation} with the added singular
+surface-force term over the domain~$\Omega_\epsilon$,
+\begin{multline}
+  \intoepdx{\rho\td{\vct u}}
+    = \intoepdx{\div\tenstr} + \intoepdx{\rho\vct f} \\
+      + \intoepdx{ \int_{\Gamma}\sigma\kappa\vct n\delta(\vct x - \vct
+        x_I(\vct s))\dif\vct s}.
+\end{multline}
+Here $\tdi{\vct u} = \partial\vct u/\partial t + \vct u\cdot\grad\vct u$
+denotes the convective derivative.  Now we apply the Gauss theorem and change
+the order of integration in the last term to obtain
+\begin{equation}
+  \intoepdx{\rho\td{\vct u}} = \intdoepds{\tenstr\cdot\vct n}
+    + \intoepdx{\rho\vct f} + \int_\Gamma\sigma\kappa\vct n\dif\vct s.
+\end{equation}
+If we let $\epsilon$ go to zero, the left-hand side and the second term on the
+right-hand side vanish, and we get
+\begin{equation}
+  0 = \int_\Gamma\left( \jmp{\tenstr}\cdot\vct n + \sigma\kappa\vct
+    n \right)\dif s.
+  \label{eq:stressjumpint}
+\end{equation}
+Since the derivation above is also valid for any subset of $\Omega_\epsilon$
+containing a part of $\Gamma$, \eqref{eq:stressjumpint} must hold for any part
+of $\Gamma$.  Therefore
+\begin{equation}
+  0 = \jmp{\vct T}\cdot\vct n + \sigma\kappa\vct n.
+\end{equation}
+With $\vct T = -p\vct I + 2\mu\vct D$ we finally get the interface condition
+for the stresses,
+\begin{equation}
+  \label{eq:stress_jump}
+  \jmp{p}\vct n - \jmp{2\mu\tenD}\cdot\vct n = \sigma\kappa\vct n.
+\end{equation}
+The surface tension force is seen to introduce a discontinuity in the normal
+stresses across the interface.  The tangential stresses are continuous.
+
+\section{Interface conditions for the pressure and the viscous term}
+The previous section gave a brief derivation of the interface conditions for
+immiscible and incompressible two-phase flow without mass transfer.  In order
+to use these conditions for the discretization of the Navier-Stokes equations
+\eqref{eq:ns1} and \eqref{eq:ns2}, we need to rewrite them into a more suitable
+form.  In particular, we want to find explicit expressions for the jump in the
+pressure $\jmp p$ and the viscous term $\jmp{\mu\grad\vct u}$.  The following
+derivation is based on \cite{Hansen05} and \cite{Kang00}.
+
+First, a jump condition for the pressure is obtained by taking the inner
+product of \eqref{eq:stress_jump} with the normal vector $\vct n$,
+\begin{equation}
+  \jmp p = \vct n\cdot\jmp{2\mu\tenD}\cdot\vct n + \sigma\kappa
+      = 2\jmp{\mu}\vct n\cdot \grad\vct u \cdot\vct n
+        + \sigma\kappa,
+  \label{eq:jump_pressure}
+\end{equation}
+where \eqref{eq:jmpngradun} was used for the second equality.
+
+To find the jump in the viscous term, it is first decomposed into an interface
+normal coordinate system as
+\begin{equation}
+  \begin{split}
+    \jmp{\mu\grad\vct u} &=
+  \left(\vct n\cdot\jmp{\mu\grad\vct u}\cdot\vct n\right)\vct n\otimes\vct n +
+  \left(\vct t\cdot\jmp{\mu\grad\vct u}\cdot\vct t\right)\vct t\otimes\vct t
+        \\ &\quad+
+  \left(\vct n\cdot\jmp{\mu\grad\vct u}\cdot\vct t\right)\vct n\otimes\vct t +
+  \left(\vct t\cdot\jmp{\mu\grad\vct u}\cdot\vct n\right)\vct t\otimes\vct n,
+  \end{split}
+\end{equation}
+where $\otimes$ denotes the dyadic product.  We already showed that
+$\jmp{\grad\vct u}\cdot\vct t = 0$ and $\vct n\cdot\jmp{\grad\vct u}\cdot\vct
+n = 0$, cf.\ \eqref{eq:jmpJut} and \eqref{eq:jmpngradun}, which gives
+\begin{align}
+  \vct n\cdot\jmp{\mu\grad\vct u}\cdot\vct n &=
+    \jmp{\mu}\,\vct n\cdot\grad\vct u\cdot\vct n, \\
+  \vct t\cdot\jmp{\mu\grad\vct u}\cdot\vct t &=
+    \jmp{\mu}\,\vct t\cdot\grad\vct u\cdot\vct t, \\
+  \vct n\cdot\jmp{\mu\grad\vct u}\cdot\vct t &=
+    \jmp{\mu}\,\vct n\cdot\grad\vct u\cdot\vct t.
+\end{align}
+We then take the inner product of \eqref{eq:stress_jump} with $\vct t$, which
+gives
+\begin{equation}
+  \vct t\cdot\jmp{\mu\left(\grad\vct u + (\grad\vct u)^T \right)}\cdot\vct n
+  = \vct t\cdot\jmp{\mu\grad\vct u} \cdot\vct n
+    + \jmp{\mu}\vct n\cdot\grad\vct u \cdot\vct t
+  = 0,
+\end{equation}
+or
+\begin{equation}
+  \vct t\cdot\jmp{\mu\grad\vct u}\cdot\vct n =
+    - \jmp{\mu}\vct n\cdot\grad\vct u \cdot\vct t.
+\end{equation}
+The jump in the viscous term becomes
+\begin{multline}
+  \jmp{\mu\grad\vct u} = \jmp{\mu} \Big(
+       (\vct n\cdot\grad\vct u\cdot\vct n)\vct n\otimes\vct n
+     + (\vct n\cdot\grad\vct u\cdot\vct t)\vct n\otimes\vct t \\
+     - (\vct n\cdot\grad\vct u\cdot\vct t)\vct t\otimes\vct n
+     + (\vct t\cdot\grad\vct u\cdot\vct t)\vct t\otimes\vct t \Big).
+\end{multline}
+This can be simplified further by noting that
+\begin{equation}
+  (\grad\vct u\cdot t)\otimes\vct t
+  = (\vct n\cdot\grad\vct u\cdot\vct t)\vct n\otimes\vct t
+    + (\vct t\cdot\grad\vct u\cdot\vct t)\vct t\otimes\vct t.
+\end{equation}
+Thus we obtain the expression for the jump in the viscous term that has been

+\begin{multline}
+  \jmp{\mu\grad\vct u} = \jmp{\mu} \Big(
+       (\vct n\cdot\grad\vct u\cdot\vct n)\vct n\otimes\vct n

+     + (\grad\vct u\cdot\vct t)\otimes\vct t \Big).

+\chapter{Numerical methods}
+\label{chap:numerical-methods}
+This chapter describes the numerical methods that have been used in this thesis
+to solve the Navier-Stokes equations for two-phase flow.  First, a brief
+introduction to the level-set method is given, which is followed by an outline
+of the two projection methods that have been used to solve the Navier-Stokes
+equations.  The spatial and temporal discretization methods are then
+summarized, and at the end of the chapter the new methods to calculate the
+curvature and the normal vectors are presented.
+
+\section{The level-set method}
+\label{sec:level-set}
+In order to solve the Navier-Stokes equations for two-phase flow, we need to
+know the location of the interface.  The level-set method proposed by
+\citet{Osher88} allows us to capture the interface location as the zero level
+set of the level-set function $\varphi(\vct x,t)$.  The level-set function is
+typically defined as a signed-distance function,
+\begin{equation}
+  \varphi(\vct x,t) = \begin{cases}
+     d(\vct x,t) & \text{if } \vct x\in\Omega_2, \\
+    -d(\vct x,t) & \text{if } \vct x\in\Omega_1, \\
+  \end{cases}
+\end{equation}
+where $d(\vct x,t)$ is the shortest distance to the interface $\Gamma$,
+\begin{equation}
+  d(\vct x,t) = \min_{\vct x_I \in \Gamma} |\vct x - \vct x_I|.
+\end{equation}
+Thus the interface can be defined implicitly as
+\begin{equation}
+  \Gamma(t) = \set{\vct x\in\Omega}{\varphi(\vct x,t)=0},
+              \quad t\in \mathbb R^+.
+\end{equation}
+
+The position of the interface is updated by solving an advection equation for
+$\varphi$,
+\begin{equation}
+  \label{eq:ls_adeq}
+  \pdt{\varphi} + \vct{\hat u}\cdot\grad\varphi = 0,
+\end{equation}
+where $\vct{\hat u}$ is the velocity at the interface extended to the entire
+domain.  We extend the interface velocity through solving
+a velocity-extrapolation equation,
+\begin{equation}
+  \label{eq:ls_velextr}
+  \pd{\vct{\hat u}}{\tau} + S(\varphi)\vct n\cdot\grad\vct{\hat u} = 0,
+  \quad \vct{\hat u}_{\tau=0} = \vct u,
+\end{equation}
+to steady state, cf.\ \cite{Adalsteinsson99,Zhao96}.  Here $\tau$ is
+a pseudo-time and $S$ is a smeared sign function which is equal to zero at the
+interface,
+\begin{equation}
+  S(\varphi) = \frac{\varphi}{\sqrt{\varphi^2+2\Delta x^2}}.
+\end{equation}
+
+When we solve the level-set equation \eqref{eq:ls_adeq}, the non-uniform
+advection will distort the signed-distance property of the level-set function,
+and numerical dissipation error adds to this distortion.  The level-set
+function is therefore reinitialized regularly by solving
+\begin{equation}
+  \label{eq:ls_reinit}
+  \begin{split}
+    \pd{\varphi}{\tau} + S(\varphi_0)(|\grad\varphi|-1) &= 0, \\
+    \varphi(\vct x,0) &= \varphi_0(\vct x),
+  \end{split}
+\end{equation}
+to steady state as proposed by \citet{Sussman94}.  The level-set function just
+before initialization is used as the initial condition $\varphi_0$.
+
+The level-set equations \eqref{eq:ls_adeq}, \eqref{eq:ls_velextr}, and
+\eqref{eq:ls_reinit} are discretized in time and space as described in the
+following sections.  The method presented by \citet{Adalsteinsson95} is used to
+improve the computational speed.  The method is often called the narrow-band
+method, since the level-set function is only updated in a narrow band across
+the interface at each time step.
+
+One of the advantages of the level-set method is that normal vectors and
+curvatures can be readily calculated from the level-set function, that is,
+\begin{align}
+  \label{eq:norm}
+  \vct n &= \frac{\grad\varphi}{|\grad\varphi|}, \\
+  \label{eq:curv}
+  \kappa &= \div\left(\frac{\grad\varphi}{|\grad\varphi|}\right).
+\end{align}
+
+\section{Projection methods}
+\label{sec:projection-method}
+We have employed two different projection methods in this thesis to solve the
+incompressible Navier-Stokes equations for two-phase flow \eqref{eq:ns1} and
+\eqref{eq:ns2}.  Papers A, B, and C used the direct projection
+scheme~1~(DP1)~\cite{Hansen05}, and Paper D used the more standard Chorin
+projection method \cite{Chorin68}.
+
+The projection methods are a family of methods for the solution of the
+incompressible Navier-Stokes equations that are based on the Helmholtz-Hodge
+theorem.  This theorem states that an arbitrary vector field can be decomposed
+into a divergence-free part and a rotation-free part.  That is, any vector
+field $\vct a$ can be written as
+\begin{equation}
+  \vct a = \vct a' + \grad\psi,
+\end{equation}
+where $\vct a'$ is a vector with $\div\vct a' = 0$ and $\psi$ is a scalar
+potential.  The proof of this theorem can be found in for instance
+\cite[§3.44]{Aris89} or \cite{Chorin00}.
+
+\subsection{The direct projection scheme 1}
+The DP1 was developed by \citet{Hansen05} and is based on a direct application
+of the Helmholtz-Hodge theorem.  We assume that the velocity $\vct u$ is
+sufficiently smooth, and then rewrite \eqref{eq:navier-stokes-2} to get
+\begin{equation}
+  \label{eq:divFreeVel}
+  \pdt{\vct u} = \vct w - \frac{\grad p}{\rho},
+\end{equation}
+where
+\begin{equation}
+  \vct w = - (\vct u\cdot\grad)\vct u + \nu\grad^2\vct u + \vct f.
+  \label{eq:continuousRightHandVector}
+\end{equation}
+The divergence of \eqref{eq:divFreeVel} yields a Poisson equation for the
+pressure,
+\begin{equation}
+  \div\left(\frac{\grad p}{\rho}\right) = \div\vct w.
+  \label{eq:PoissonDP1}
+\end{equation}
+The DP1 scheme follows from a direct numerical discretization of the above
+equations.  First, $\vct w$ is calculated with
+\eqref{eq:continuousRightHandVector}.  Then the pressure is found by solving
+the Poisson equation \eqref{eq:PoissonDP1}.  Finally, an Euler step is used to
+solve \eqref{eq:divFreeVel}, that is,
+\begin{equation}
+  \vct u^{n+1} = \vct u^n + \Delta t\left(\vct w - \frac{\grad p}{\rho}\right).
+  \label{eq:dp1-update}
+\end{equation}
+
+\subsection{The Chorin projection method}
+The Chorin projection method was presented by \citet{Chorin68}, and is today
+one of the standard methods for solving the Navier-Stokes equations, e.g.\
+\cite{Walker12}.  The method is briefly presented in the following.
+
+Let $\Delta t$ be the time step, and consider the discretization of the
+momentum equation \eqref{eq:navier-stokes-2} with the forward Euler method,
+\begin{equation}
+  \frac{\vct u^{n+1} - \vct u^n}{\Delta t}
+  = -\vct u^n\cdot\grad\vct u^n
+    - \frac{\grad p^{n+1}}{\rho} + \frac\mu\rho\lapl\vct u^n + \vct f,
+  \label{eq:discmomeq}
+\end{equation}
+where $\vct u^n\equiv\vct u(\vct x,n\Delta t)$ and $p^n\equiv p(\vct x,n\Delta
+t)$ are assumed known at time level $n$.  Note that the pressure gradient is
+evaluated at time level $n+1$.  Next, to solve \eqref{eq:discmomeq} in two
+steps, we introduce the intermediate velocity field $\vct u^\star$,
+\begin{equation}
+  \frac{\vct u^{n+1} - \vct u^\star + \vct u^\star - \vct u^n}{\Delta t}
+  = -\vct u^n\cdot\grad\vct u^n
+    - \frac{\grad p^{n+1}}{\rho} + \frac\mu\rho\lapl\vct u^n + \vct f,
+\end{equation}
+which is chosen such that
+\begin{align}
+  \label{eq:ustar}
+  \frac{\vct u^\star - \vct u^n}{\Delta t}
+    &= -\vct u^n\cdot\grad\vct u^n + \frac\mu\rho\lapl\vct u^n + \vct f, \\
+  \label{eq:unext}
+  \frac{\vct u^{n+1} - \vct u^\star}{\Delta t} &= - \frac{\grad p^{n+1}}{\rho}.
+\end{align}
+From \eqref{eq:ustar} we get an explicit expression for $\vct u^\star$,
+\begin{equation}
+  \vct u^{\star} = \vct u^n
+    + \Delta t\left(-\vct u^n\cdot\grad\vct u^n
+        + \frac\mu\rho\,\lapl\vct u^n + \vct f\right).
+\end{equation}
+Next, the divergence of \eqref{eq:unext} and $\div\vct u^{n+1} = 0$ yields
+a Poisson equation for the pressure,
+\begin{equation}
+  \div\left(\frac{\grad p^{n+1}}{\rho}\right)
+    = \frac{\div\vct u^\star}{\Delta t}.
+  \label{eq:PoissonChorin}
+\end{equation}
+Finally, we obtain for \eqref{eq:unext}
+\begin{equation}
+  \vct u^{n+1} = \vct u^\star - \Delta t\frac{\grad p^{n+1}}{\rho}.
+  \label{eq:velcorrection}
+\end{equation}
+
+\section{Spatial discretization}
+\label{sec:x-discr}
+The governing equations \eqref{eq:ns1}, \eqref{eq:ns2}, \eqref{eq:ls_adeq},
+\eqref{eq:ls_velextr}, and \eqref{eq:ls_reinit} are discretized on a staggered
+grid~\cite{Harlow65}, where the scalar values are located at the cell centres
+and the vector values are located at the cell edges, see
+\cref{fig:staggered-grid}.  The domain boundary coincides with cell edges, and
+the fixed grid spacing is $\Delta x$ in the $x$ direction and $\Delta y$ in the
+$y$ direction.

+\end{figure}
+
+The $x$- and $y$-derivatives, divergence, and Laplacian operators are

+\begin{align}
+  \left. G_x p \right|_{i+\frac 1 2,j}
+    &= \frac{p_{i+1,j} - p_{i,j}}{\Delta x}, \\

+       + \frac{p_{i,j+1} - 2p_{i,j} + p_{i,j-1}}{(\Delta y)^2},
+\end{align}
+respectively.  Here $\vct u = (u,v)$ is a vector and $p$ is a scalar.  Note
+that the gradient of a scalar is a vector and has values located at the cell
+edges.  These definitions are consistent with the staggered grid, since the
+gradient returns a vector with components defined on the cell faces, while the
+divergence and the Laplacian returns a scalar defined at the cell centres.
+
+\subsection{Advective terms}
+The advective terms, $\vct u\cdot\grad\vct u$ in the momentum equation
+\eqref{eq:ns2} and $\vct{\hat u}\cdot\grad\varphi$ in the level-set equation
+\eqref{eq:ls_adeq}, and the normal derivative $\vct n\cdot\grad\vct{\hat u}$ in
+the velocity-extrapolation equation \eqref{eq:ls_velextr} are discretized with
+the weighted essentially non-oscillatory (WENO) scheme, cf.~\cite{Fedkiw99}
+and~\cite{Jiang96}.  The WENO scheme is a high-order upwind scheme that is
+fifth-order accurate in smooth regions.  In nonsmooth regions the accuracy is
+reduced to a minimum of third order.  The following is a brief outline of the
+WENO scheme.
+
+First, when we calculate the advective term for the velocity, the vector
+components are required on all cell edges.  That is, we must interpolate the
+$x$-component of the velocity to the location of the $y$-component of the
+velocity and vice versa.  To do this we use a linear interpolation,
+\begin{align}
+  u_{i,j+\frac 1 2} &= \frac 1 4\left(
+      u_{i-\frac 1 2,j  } + u_{i-\frac 1 2,j+1}
+    + u_{i+\frac 1 2,j+1} + u_{i+\frac 1 2,j  } \right), \\
+  v_{i+\frac 1 2,j} &= \frac 1 4\left(
+      v_{i,  j-\frac 1 2} + v_{i+1,j-\frac 1 2}
+    + v_{i+1,j+\frac 1 2} + v_{i  ,j+\frac 1 2} \right).
+\end{align}
+
+Similarly, when we calculate the advective term for the level-set function
+$\varphi$, we first interpolate the velocity to the scalar grid,
+\begin{align}
+  u_{i,j} &= \frac 1 2\left( u_{i+\frac 1 2,j} + u_{i-\frac 1 2,j} \right), \\
+  v_{i,j} &= \frac 1 2\left( v_{i,j+\frac 1 2} + v_{i,j-\frac 1 2} \right).
+\end{align}
+
+We now consider the WENO scheme for the advective operator in 1D at the point
+$x_{i+\frac 1 2}$.  The scheme extends naturally to higher dimensions.  First,
+if $u_{i+\frac 1 2} = 0$, then
+\begin{equation}
+  \left. u\pd u x \right|_{i+\frac 1 2} = 0.
+\end{equation}
+Otherwise we need to calculate a set of five differences that depend on the
+upwind direction.  The differences are denoted $\Delta v_k$ for $k=1,\dots,5$.
+If $u_{i+\frac 1 2}>0$, then we calculate
+\begin{equation}
+  \Delta v_k = \frac{u_{i+\frac{2k-5} 2} - u_{i+\frac{2k-7} 2}}{\Delta x}.
+\end{equation}
+Otherwise if $u_{i+\frac 1 2}<0$, we calculate
+\begin{equation}
+  \Delta v_k = \frac{u_{i-\frac{2k-9} 2} - u_{i-\frac{2k-7} 2}}{\Delta x}.
+\end{equation}
+Next we calculate expressions for the smoothness of three substencils,
+\begin{align}
+  S_1 &= \frac{13}{12}(\Delta v_1 - 2\Delta v_2 + \Delta v_3)^2
+    + \frac 1 4 (\Delta v_1 - 4\Delta v_2 + 3\Delta v_3)^2, \\
+  S_2 &= \frac{13}{12}(\Delta v_2 - 2\Delta v_3 + \Delta v_4)^2
+    + \frac 1 4 (\Delta v_2 - \Delta v_4)^2, \\
+  S_3 &= \frac{13}{12}(\Delta v_3 - 2\Delta v_4 + \Delta v_5)^2
+    + \frac 1 4 (3\Delta v_3 - 4\Delta v_4 + \Delta v_5)^2,
+\end{align}
+where a small $S$ indicates a smooth substencil.  These smoothness factors are
+then used to compute weights for the substencils,
+\begin{equation}
+  w_k = \frac{b_k}{b_1+b_2+b_3},
+\end{equation}
+for $k = 1,2,3$, where
+\begin{equation}
+  b_1 = \frac 1 {10}\frac 1 {(\epsilon+S_1)^2},\quad
+  b_2 = \frac 6 {10}\frac 1 {(\epsilon+S_2)^2},\quad
+  b_3 = \frac 3 {10}\frac 1 {(\epsilon+S_3)^2}.
+\end{equation}
+Here $\epsilon$ is a regularization parameter that is used to avoid division by
+zero.  We have used $\epsilon = 10^{-6}$ in this work.  Finally, the WENO
+scheme for the gradient becomes
+\begin{multline}
+  \left. \pd u x \right|_{i+\frac 1 2} \simeq
+      w_1\left(\frac 1 3\Delta v_1 - \frac 7 6\Delta v_2
+        + \frac{11} 6 \Delta v_3\right) \\
+    + w_2\left(-\frac 1 6\Delta v_2 + \frac 5 6\Delta v_3
+        + \frac 1 3 \Delta v_4\right) \\
+    + w_3\left(\frac1 3\Delta v_3 + \frac 5 6\Delta v_4
+        - \frac 1 6 \Delta v_5\right).
+\end{multline}
+
+\subsection{The viscous term}
+The viscous term $\mu\lapl\vct u$ in the Navier-Stokes equations is discretized
+by standard second-order central differences using the ghost-fluid method
+(GFM)~\cite{Fedkiw99,Kang00,Liu00}.  This method includes the jump in the
+viscous term at the interface \eqref{eq:jumptens} in the discretization stencil
+in a sharp manner.
+
+In the following we present the GFM scheme in the one-dimensional case.  The
+extension to higher dimensions is straightforward.  In order to simplify the
+notation, we omit the half indices and let $k\equiv i+\frac 1 2$.  Further, we
+consider a general case where
+\begin{equation}
+  \jmp u = a_\Gamma, \qquad \jmp{\mu\pd u x} = b_\Gamma.
+\end{equation}
+For the viscous term, $a_\Gamma = 0$, cf.\ \eqref{eq:jmpu}, and $b_\Gamma$ is
+given by the jump tensor~\eqref{eq:jumptens}.  The jump tensor is calculated at
+the cell centres near the interface with the second-order central-difference
+scheme.  It is then interpolated linearly to the cell edges, from where it is
+again interpolated linearly to the interface when needed.
+
+If the interface does not cross the stencil, then the GFM scheme reduces to the
+standard second-order central-difference stencil.  Else there are four
+stencils, depending on the location of the interface.  One such interface
+configuration is sketched in \cref{fig:gfm-scheme-example}.  In all the
+stencils, $\theta$ is defined as the relative distance from the interface to
+the node on the left, for instance
+\begin{equation}
+  \theta = \frac{|\varphi_{k}|}{|\varphi_{k}| + |\varphi_{k+1}|},
+\end{equation}
+where $\varphi_k$ and $\varphi_{k+1}$ are the level-set function values
+linearly interpolated to the vector grid.  The four stencils are given below,
+where $h\equiv\Delta x$.
+\begin{enumerate}
+  \item Phase 1 is to the left and interface lies between $k$ and $k+1$:
+    \begin{align}
+      \begin{split}
+        \left.\pd{} x\left(\mu\pd u x\right)\right|_{x_k}
+          &= \frac{\hat\mu\left(u_{k+1} - u_{k}\right)
+                 - \mu_1\left(u_{k} - u_{k-1}\right)}{h^2} \\
+          &\qquad
+             - \frac{\hat\mu a_\Gamma}{h^2}
+             - \frac{\hat\mu b_\Gamma (1-\theta)}{\mu_2 h},
+      \end{split} \\
+       \hat\mu &= \frac{\mu_1\mu_2}{\theta\mu_2 + (1-\theta)\mu_1}.
+    \end{align}
+  \item Phase 1 is to the left and interface lies between $k-1$ and $k$:
+    \begin{align}
+      \begin{split}
+        \left.\pd{} x\left(\mu\pd u x\right)\right|_{x_k}
+          &= \frac{\mu_2\left(u_{k+1} - u_{k}\right)
+                - \hat\mu\left(u_{k} - u_{k-1}\right)}{h^2} \\
+          &\qquad
+            + \frac{\hat\mu a_\Gamma}{h^2}
+            - \frac{\hat\mu b_\Gamma \theta}{\mu_1 h},
+      \end{split} \\
+      \hat\mu &= \frac{\mu_1\mu_2}{\theta\mu_2 + (1-\theta)\mu_1}.
+    \end{align}
+  \item Phase 2 is to the left and interface lies between $k$ and $k+1$:
+    \begin{align}
+      \begin{split}

+\subsection{Pressure Poisson equation}
+\label{sec:pressure-poisson}
+The Laplace operator in the Poisson equations \eqref{eq:PoissonDP1} and
+\eqref{eq:PoissonChorin} is also discretized by standard second-order central
+differences using the GFM~\cite{Kang00,Liu00}.  The GFM was discussed in the
+previous section, where stencils were given for the viscous term in the
+one-dimensional case.  For the pressure, the stencils are the same except we
+use $p$ instead of $u$, and $1/\rho$ and $1/\hat\rho$ instead of $\mu$ and
+$\hat\mu$.  To find the jump in the pressure at the interface, $\jmp
+p = a_\Gamma$, the jump condition \eqref{eq:jump_pressure} is calculated at the
+cell centres and then interpolated to the interface.  In addition, we use that
+$b_\Gamma = 0$, which is justified by \citet[Section~3.7]{Kang00}.
+
+The resulting linear system for the pressure is solved with a solver from the
+Portable, Extensible Toolkit for Scientific Computation (PETSc)~\cite{PETSc}.
+PETSc makes available a large selection of solvers.  In most cases, we used the
+direct solver based on LU factorisation or the conjugate gradient method with
+incomplete Cholesky factorisation.  In some cases, we used the GMRES solver
+with a preconditioner, either incomplete LU factorisation or an algebraic
+multigrid method.  See \cite{PETSc} for more details and a list of available
+methods, and see for example~\cite{Iserles09} or~\cite{Saad03} for an
+introduction to linear solvers.
+
+Finally, the gradient of the pressure, used in \eqref{eq:divFreeVel} and
+\eqref{eq:velcorrection}, is also calculated with the GFM.  In one dimension,
+the stencil is
+\begin{align}
+  \left. \frac 1 \rho \pd p x\right|_{i+\frac 1 2}
+           &= \frac 1 {\hat\rho} \frac{(p_{i+1} - a_\Gamma) - p_i} h, \\
+  \hat\rho &= \theta\rho_1 + (1-\theta)\rho_2,
+\end{align}
+if $\phi_i\leq 0$ and $\phi_{i+1}>0$, or else
+\begin{align}
+  \left. \frac 1 \rho \pd p x\right|_{i+\frac 1 2}
+           &= \frac 1 {\hat\rho} \frac{(p_{i+1} + a_\Gamma) - p_i} h, \\
+  \hat\rho &= \theta\rho_2 + (1-\theta)\rho_1,
+\end{align}
+where
+\begin{equation}
+  \theta = \frac{|\varphi_{i}|}{|\varphi_{i}| + |\varphi_{i+1}|}.
+\end{equation}
+
+\section{Temporal discretization}
+\label{sec:t-discr}
+The temporal discretization is done with the explicit strong
+stability-preserving Runge-Kutta (SSP-RK) schemes, see
+\cite{Ketcheson05,Shu88}.  The idea behind the SSP-RK schemes is to preserve
+the stability of a low-order method when it is extended to higher order.  It is
+argued in \cite{Gottlieb01} that if one extends the forward Euler method, which
+is total variation diminishing (TVD) for a suitable discretization of a scalar
+conservation law, to a non-SSP higher-order method, then overshoots may occur
+at discontinuities.
+
+An SSP-RK method can be written as a convex sum of explicit Euler steps with
+time step $\Delta t$,
+\begin{equation}
+  \mathcal E\left(x^n\right) = x^n + \Delta t \mathcal F(x^n,t^n).
+\end{equation}
+where $\mathcal F$ is the residual of the PDE to be solved.  In this thesis we
+have used two methods:  The third-order three-stage SSP-RK method~\cite{Shu88},
+\begin{equation}
+  \begin{split}
+    x^{(1)} &= \mathcal E\left(x^n\right), \\
+    x^{(2)} &= \frac 3 4 x^n + \frac 1 4\mathcal E\left(x^{(1)}\right), \\
+    x^{n+1} &= \frac 1 3 x^n + \frac 2 3\mathcal E\left(x^{(2)}\right),
+  \end{split}
+  \label{eq:ssprk33}
+\end{equation}
+and the third-order four-stage SSP-RK method~\cite{Kraaijevanger91},
+\begin{equation}
+  \begin{split}
+    x^{(1)} &= \frac 1 2 x^n + \frac 1 2\mathcal E\left(x^n\right), \\
+    x^{(2)} &= \frac 1 2 x^{(1)} + \frac 1 2\mathcal E\left(x^{(1)}\right), \\
+    x^{(3)} &= \frac 2 3 x^n + \frac 1 6 x^{(2)}
+               + \frac 1 6\mathcal E\left(x^{(2)}\right), \\
+    x^{n+1} &= \frac 1 2 x^{(3)} + \frac 1 2\mathcal E\left(x^{(3)}\right).
+  \end{split}
+  \label{eq:ssprk34}
+\end{equation}
+
+The semi-discretized velocity-extrapolation equation \eqref{eq:ls_velextr} and
+level-set reinitialization equation \eqref{eq:ls_reinit} can be written as
+systems of ordinary differential equations (ODEs) of the form
+\begin{equation}
+  \od{\vct \psi} \tau = \vct F(\vct\psi,\tau),
+\end{equation}
+where $\vct\psi$ is a vector containing the discrete variables and $\vct F$
+contains the spatially discretized terms.  The explicit Euler step becomes
+\begin{equation}
+  \mathcal E(\vct\psi^n) = \vct\psi^n + \Delta\tau \vct F(\vct\psi^n,\tau^n).
+\end{equation}
+In this thesis, these equations are solved with the third-order four-stage
+SSP-RK method \eqref{eq:ssprk34}.  The four-stage method is used because it is
+more accurate than the three-stage method.  We wanted to make sure that the
+error is mainly dominated by the spatial discretization.
+
+The semi-discretized Navier-Stokes equations \eqref{eq:navier-stokes-1} and
+\eqref{eq:navier-stokes-2} are solved together with the level-set advection
+equation \eqref{eq:ls_adeq} with the third-order three-stage SSP-RK method
+\eqref{eq:ssprk33}.  Here an explicit Euler step $\mathcal E(\vct
+u^n,\varphi^n)$ consists of the following steps:
+\begin{enumerate}
+  \item Calculate the curvature and the normal vectors from $\varphi^n$ with
+    one of the methods described in \cref{sec:curvature}.
+  \item Calculate the intermediate velocity field, either $\vct w$
+    \eqref{eq:continuousRightHandVector} or $\vct u^\star$ \eqref{eq:ustar}.
+  \item Solve the Poisson equation \eqref{eq:PoissonDP1} or
+    \eqref{eq:PoissonChorin} for the pressure as described in
+    \cref{sec:pressure-poisson}.
+  \item Correct the velocity field with either \eqref{eq:dp1-update} or
+    \eqref{eq:velcorrection}.
+  \item Advect the level-set function $\varphi^n$ with \eqref{eq:ls_adeq}.
+\end{enumerate}
+
+\section{Time step restriction}
+\label{sec:deltaT}
+We employ the Courant-Friedrich-Lewy~(CFL) condition to allow adaptive time
+stepping and to enforce stability.  The CFL condition that is used in this
+thesis is
+\begin{equation}
+  \Delta t = \frac{C}{\frac{C_c + C_v} 2
+             + \sqrt{(C_c + C_v)^2 + 4C_g^2 + 4C_s^2}},
+\end{equation}
+where the CFL restriction $C<1$, and $C_c$, $C_v$, $C_s$, and $C_g$ represent
+the contributions from the convective term, the viscous stresses, the surface
+tension, and the gravity, respectively,
+\begin{align}
+  C_c &=  \frac{\max_{i,j}|u_{i,j}|}{\Delta x}
+        + \frac{\max_{i,j}|v_{i,j}|}{\Delta y}, \\
+  C_v &= 2\max\left(\frac{\mu_1}{\rho_1},\frac{\mu_2}{\rho_2}\right)
+         \left(\frac{1}{\Delta x^2} + \frac{1}{\Delta y^2}\right), \\
+  C_s &= \sqrt{\frac{\sigma\max_{i,j}|\kappa_{i,j}|}
+                    {\max(\rho_1,\rho_2)\min(\Delta x^2,\Delta y^2)}}, \\
+  C_g &= \sqrt{\frac{|g_x|}{\Delta x} + \frac{|g_y|}{\Delta y}}.
+\end{align}
+This CFL condition is discussed in more detail by~\citet{Lervag08}, and it is
+based on the condition by \citet{Kang00}.
+
+\section{Axisymmetry}
+For axisymmetric flow, the governing equations \eqref{eq:ns1} and
+\eqref{eq:ns2} become
+\begin{equation}
+  \frac 1 r \pd{} r\left(r u\right) + \pd v z = 0,
+\end{equation}
+\begin{multline}
+  \rho\left(\pdt u + u\pd u r + v\pd u z\right) = -\pd p r \\
+    + \mu\left(\frac 1 r \pd{} r\left(r \pd u r\right)
+          + \pdd u z - \frac u {r^2}\right) + \rho f_r + {f_s}_r,
+\end{multline}
+and
+\begin{multline}
+  \rho\left(\pdt v + u\pd v r + v\pd v z\right) = -\pd p z \\
+    + \mu\left(\frac 1 r \pd{} r\left(r \pd v r\right)
+      + \pdd v z\right) + \rho f_z + {f_s}_z.
+\end{multline}
+Here $u$ and $v$ are the radial and axial velocity components, $f_r$ and $f_z$
+are the radial and axial body-force components, and ${f_s}_r$ and ${f_s}_z$ are
+the radial and axial components of the singular surface force, respectively.
+The equations are solved as explained in the previous sections.
+
+\section{Discretization of the curvature and the normal vector}
+\label{sec:curvature}
+As stated in \cref{sec:level-set}, the normal vector \eqref{eq:norm} and the
+curvature \eqref{eq:curv} can be calculated from the level-set function as
+\begin{align*}
+  \vct n &= \frac{\grad\varphi}{|\grad\varphi|}, \\
+  \kappa &= \div\left(\frac{\grad\varphi}{|\grad\varphi|}\right).
+\end{align*}
+They are typically discretized with the standard second-order
+central-difference scheme, cf.\ \cite{Kang00,Sethian03,Xu06}.  The normal
+vector is calculated at the cell edges, and the curvature is calculated at the
+grid nodes.  The curvature is then interpolated to the interface where needed
+with linear interpolation, for instance with
+\begin{equation}
+  \kappa_\Gamma = \frac{|\varphi_{i,j}|\kappa_{i+1,j}
+  + |\varphi_{i+1,k}|\kappa_{i,j}}{|\varphi_{i,j}| + |\varphi_{i+1,j}|}.
+  \label{eq:curvature-gamma}
+\end{equation}
+
+If the level-set method is used to capture non-trivial geometries, then it will
+contain kink regions, that is, areas where the gradient of the level-set
+function is discontinuous.  \Cref{fig:level-set-function} shows a simple
+example of such a kink region for a level-set function in a one-dimensional
+domain that captures two interfaces, one on each side of $x_i$.  The kink at
+$x_i$ may lead to large errors both for the curvature and the normal vector if
+one is not careful.  Errors in the curvature lead to errors in the surface
+tension force and in the pressure, which in turn lead to errors in the
+interface evolution and in the two-phase flow.  Errors in the normal vector
+affect both the calculation of the viscous jump condition and the advection of
+the interface.  If the level-set method is used to study for example
+coalescence and breakup of drops, these errors may severely affect the
+simulations.

+
+This problem was to our knowledge first described by \citet{Smereka03}, who
+increase the numerical smoothing in the curvature discretization to lessen the
+effect.  Several non-smearing approaches have subsequently been developed.
+\citet{Macklin05} used the level-set method to study tumor growth, and they
+present a one-sided direction-difference scheme for the discretization of the
+normal vector and the curvature.  Later, \citet{Macklin06} presented an
+improved geometry-aware curvature discretization, where the curvature is
+calculated based on a local least-squares parametrisation of the interface.
+
+A different approach to avoid the kinks was presented by \citet{Salac08}.  They
+used a level-set extraction technique, where an extraction algorithm was used
+to reconstruct separate level-set functions for each distinct \emph{body}.  The
+term \emph{body} is used here to denote a subset of a given phase or fluid.
+For example, in the case of two drops of water colliding in air, the water
+drops would make two distinct bodies.  One can also avoid the extraction
+algorithm altogether by use of multiple marker functions for different bodies,
+see for instance \cite{Coyajee09,Kwakkel12}.  Note, however, that the latter
+approach means that the different bodies will not coalesce unless explicit
+action is made, cf.~\cite{Kwakkel13}.  Also, both of the approaches mentioned
+here fails to handle the problem of kinks from a single body.  That is, there
+may still be kink areas due to deformed bodies, for instance bodies with thin
+filaments or tails, or bodies shaped like horse shoes.
+
+In the following, we first present the direction-difference
+scheme~\cite{Macklin05}.  We then describe the curve-fitting discretization
+method and the local level-set extraction method.
+
+\subsection{Direction-difference scheme}
+\label{sec:dds}
+The direction-difference scheme (DDS) was introduced by \citet{Macklin05}.  It
+uses a quality function to ensure that the difference stencils never cross any
+kink regions.  The DDS is used in Papers A--C to calculate the normal vectors.
+However, in Paper C it is shown that the DDS does not always yield an accurate
+approximation of the normal vector.
+
+The basic strategy is to use a combination of central differences and one-sided
+differences based on the values of a quality function,
+\begin{equation}
+  Q(\vct x) = \left| 1 - |\grad\varphi(\vct x)|\right|.
+  \label{eq:quality}
+\end{equation}
+The quality function is approximated with central differences, and is used to
+detect the areas where the level-set function differs from the signed-distance
+function.  In the following, let $Q_{i,j} \equiv Q(\vct x_{i,j})$ and define
+a parameter $\eta>0$.  This threshold parameter is tuned such that the quality
+function will detect all the kinks.
+
+The quality function is used to define a direction function,
+\begin{equation}
+  \vct D(\vct x_{i,j}) = (D_x(\vct x_{i,j}), D_y(\vct x_{i,j})),
+\end{equation}
+where
+\begin{equation}
+  D_x(\vct x_{i,j}) = \begin{cases}
+    -1 & \text{if $Q_{i-1,j}<\eta$ and $Q_{i+1,j}\geq\eta$,} \\
+     1 & \text{if $Q_{i-1,j}\geq\eta$ and $Q_{i+1,j}<\eta$,} \\
+     0 & \text{if $Q_{i-1,j}<\eta$ and $Q_{i,j}<\eta$ and $Q_{i+1,j}<\eta$,} \\
+     0 & \text{if $Q_{i-1,j}\geq\eta$ and $Q_{i,j}\geq\eta$ and
+         $Q_{i+1,j}\geq\eta$,} \\
+     4 & \text{otherwise.}
+  \end{cases}
+  \label{eq:dirfunc}
+\end{equation}
+$D_y(\vct x_{i,j})$ is defined in a similar manner.  If $D_x(\vct x_{i,j})
++ D_y(\vct x_{i,j}) > 2$, then $\vct D(\vct x_{i,j})$ is chosen as the vector
+normal to $\grad\varphi(\vct x_{i,j})$.  It is normalized, and the sign is
+chosen such that it points in the direction of the best quality.  See
+\cite{Macklin05} for more details.
+
+The DDS is then defined as
+\begin{equation}
+  \partial_x f_{i,j} = \begin{cases}
+    \frac{f_{i,j} - f_{i-1,j}}{\Delta x}    & \text{if $D_x(x_i,y_j) = -1$,} \\
+    \frac{f_{i+1,j} - f_{i,j}}{\Delta x}    & \text{if $D_x(x_i,y_j) =  1$,} \\
+    \frac{f_{i+1,j} - f_{i-1,j}}{2\Delta x} & \text{if $D_x(x_i,y_j) =  0$,}
+  \end{cases}
+  \label{eq:Ddifference}
+\end{equation}
+and similarly for $\partial_y f_{i,j}$, where $f_{i,j}$ is a piecewise smooth
+function.  The DDS is equivalent to using central differences in smooth areas
+and one-sided differences in areas close to the kinks.
+
+\subsection{Curve-fitting discretization method}
+\label{sec:curvature-curve-fitting}
+The curve-fitting discretization method (CFDM) was first presented
+in~\cite{Lervag11} and is based on the method by \citet{Macklin06}.  The main
+idea is to identify kink regions with the quality function \eqref{eq:quality},
+and to use a curve parametrisation of the closest interface to calculate the
+curvature in regions where the quality function is larger than the threshold
+parameter, $\eta$.
+
+The CFDM applied to the curvature or the normal vector at the grid point $\vct
+x_{i,j}$ can be summarized as follows.  See also \cref{fig:cfdm}, which shows
+an example of the CFDM used at $\vct x_{i,j}$.
+\begin{enumerate}
+  \item If the quality of the level-set function in the neighbourhood of $\vct
+    x_{i,j}$ is good, that is
+    \[
+      Q(\vct{x}_{n,m}) \le \eta \; \forall (n,m) \in [i-1,i+1]\times[j-1,j+1],
+    \]
+    then we use a standard discretization.  Otherwise continue to the next
+    step.
+  \item Locate the closest interface, $\Gamma$.
+  \item Find a set of points on the located interface, $\vct x_1, \dots, \vct
+    x_n \in \Gamma$.
+  \item Create a parametrisation $\vct \gamma(s)$ of the points $\vct x_1,
+    \dots, \vct x_n$.
+  \item Use the parametrisation $\vct \gamma(s)$ to calculate a local level-set
+    function.
+  \item Use a standard discretization of the local level-set function to
+    calculate the curvature or the normal vector.
+\end{enumerate}

+\subsection{Local level-set extraction method}
+\label{sec:lolex}
+The local level-set extraction (LOLEX) method is based on the method presented
+by \citet{Salac08}, here called the SLM.  It was found that the latter method
+was insufficient, because it did not treat all the kink problems.  The LOLEX
+method is therefore a further development of the SLM, in that it handles the
+kink regions in a more general manner.
+
+The LOLEX method applied to the curvature or the normal vector at a grid point
+$\vct x_{i,j}$ is summarized by the following algorithm.  The algorithm is
+presented with 2D notation for clarity, and extends easily to 3D.  See also
+\cref{fig:lolex}, which gives a simple example of the procedure.
+\begin{enumerate}
+  \item If the quality in the neighbourhood of $\vct x_{i,j}$ is good, that is
+    \[
+      Q(\vct{x}_{n,m}) \le \eta \; \forall (n,m) \in [i-1,i+1]\times[j-1,j+1],
+    \]
+    then we use a standard discretization.  Otherwise continue to the next
+    step.
+  \item Copy a small, local square centred around $\vct x_{i,j}$ from the
+    level-set function $\varphi$ into a local array $\varphi_\text{loc}$.
+  \item Identify and enumerate all the \emph{bodies} in the local array
+    $\varphi_\text{loc}$.  A \emph{body} is here defined as a set of
+    neighbouring points where $\varphi_\text{loc}<0$, see \cref{fig:lolex}.
+    There will be $n\geq 0$ bodies in any given $\varphi_\text{loc}$ array.
+  \item If no body is identified, that is, if $n=0$, then use a standard
+    discretization with the global level-set function $\varphi$.  Otherwise
+    continue to the next step.
+  \item For each body $n$, extract the relevant parts of $\varphi_\text{loc}$
+    into an array $\varphi_\text{loc}^n$.  If necessary, extrapolate values to
+    ghost cells.
+  \item For each body, $n$, reinitialize $\varphi_\text{loc}^n$.
+  \item At this step, all the bodies in the local grid have their own
+    local level-set functions that have been reinitialized to proper
+    signed-distance functions.  Due to the separation of the bodies, there
+    are no longer any kinks.
+  \item Use the standard discretization of the curvature and the normal
+    vector at the local level-set function that represents the body that is
+    closest to $\vct x_{i,j}$.

+\chapter{The diffuse-domain approach}
+\label{chap:diffuse-domain}
+In the previous chapters, we have considered the modelling of two-phase flows,
+and in particular methods for calculating the curvature and normal vector with
+the level-set method in a reliable manner.  In this chapter, we consider
+a different problem of a more general nature:  How to solve partial
+differential equations (PDEs) in complex domains.  In particular, we consider
+an extension of a diffuse-domain method (DDM) by a high-order correction term
+that gives increased accuracy with respect to interface-width refinements.
+
+We begin with a short introduction to the diffuse-domain approach.  We then
+outline how it can be used to derive a DDM for the steady reaction-diffusion
+equation with Neumann boundary conditions.  Next, we continue with a brief
+introduction to the method of matched asymptotic expansions.  Finally, we
+introduce the high-order correction term derived in Paper~E and show that the
+resulting DDM converge with second order in the diffuse-interface width to the
+original problem.  The analysis also shows that the correction term is not
+necessary for second-order convergence.
+
+\section{Introduction}
+There exist several methods for solving PDEs in complex domains.  Most of them
+have in common that they require tools or methods that are not frequently
+available in standard finite-element or finite-difference software packages.
+Examples of such methods include the immersed-interface method
+\cite{LeVeque94}, the matched interface and boundary method \cite{Zhou06}, the
+extended and composite finite-element method \cite{Dolbow09}, embedded boundary
+methods \cite{Johansen98}, cut-cell methods \cite{Ji06}, and ghost-fluid
+methods \cite{Fedkiw99}.  A different approach, known as the fictitious domain
+method~\cite{Glowinski94,Glowinski96} or the domain imbedding
+method~\cite{Buzbee71}, either augments the original system with equations for
+Lagrange multipliers to enforce the boundary conditions, or use the penalty
+method to enforce the boundary conditions weakly.  For a more complete list of
+references, see Paper~E.
+
+The DDM is an alternative method for solving PDEs in complex domains.  The main
+idea is to use an implicit representation of the boundary, where the sharp
+boundary is replaced by a diffuse layer.  The PDEs are then reformulated on
+a larger, regular domain, and the boundary conditions are incorporated via
+source terms in the diffuse layer.  When the thickness of the diffuse layer is
+reduced, these source terms tend towards singular source terms.  The resulting
+PDEs can then be solved with the use of standard tools and methods.
+
+The diffuse-domain approach was first introduced by \citet{Kockelkoren03} to
+study diffusion inside a cell with homogeneous Neumann boundary conditions at
+the cell boundary.  It was later used by \citet{Li09} to develop a DDM for
+solving PDEs in complex evolving domains with Dirichlet, Neumann and Robin
+boundary conditions, which is hereafter called the DDM1.  The DDM1 has been
+used by \citet{Teigen09-b}, who modelled bulk-surface coupling of material
+quantities on a deformable interface.  It was also used by \citet{Aland10} to
+simulate incompressible two-phase flows in complex domains in 2D and 3D, and by
+\citet{Teigen11} to study two-phase flows with soluble surfactants.
+
+An analysis of the error behaviour of the diffuse-domain approach was done by
+\citet{Franz12} for a diffuse-domain approximation of an elliptic problem with
+Dirichlet boundary conditions.  They considered the infinity norm of the
+difference of the approximated solution and the exact solution, and their
+analysis shows that the approximation quality is of order one in the interface
+width.
+
+In Paper~E, we present the DDM2, which is an extension of the DDM1 by
+a high-order correction term.  The DDM2 is derived for elliptic problems with
+Neumann and Robin boundary conditions, and it is shown to be asymptotically
+second-order accurate in the interface width.  However, the analysis in Paper~E
+is somewhat lacking in that it assumes that the DDM1 is only first-order
+accurate.  In the following sections, we extend the analysis of Paper~E and
+show that the DDM1 is also second-order accurate.  The analysis is shown for
+the steady reaction-diffusion equation with Neumann boundary conditions, but
+the same technique also applies for the corresponding Robin problem.
+
+\section{The DDM for a Neumann problem}
+Consider the steady reaction-diffusion equation with Neumann boundary
+conditions,
+\begin{equation}
+  \begin{alignedat}{2}
+    \lapl u - u  &= f        & \txin D, \\
+    \ndot\grad u &= g \qquad & \txon \partial D,
+  \end{alignedat}
+  \label{eq:ddan}
+\end{equation}
+where $f$ and $g$ are given.  Let $\chi_D$ be the characteristic function of
+$D$,
+\begin{equation}
+  \chi_D = \begin{cases}
+    1 & \text{if $x\in D$,} \\
+    0 & \text{if $x\notin D$.}
+  \end{cases}
+\end{equation}
+The main idea with the diffuse-domain approach is to extend the original
+equation \eqref{eq:ddan} into a larger and regular domain $\Omega\supset D$, as
+depicted in \cref{fig:ddadomain}.  The extension can be written as
+\begin{equation}
+  \div(\chi_D\grad u) - \chi_D u + \text{BC} = \chi_D f,
+  \label{eq:ddm}
+\end{equation}
+where BC is a singular source term that represents the physical boundary
+condition on $\partial\Omega$.

+\end{figure}
+
+The characteristic function is typically approximated by the phase-field
+function,
+\begin{equation}
+  \chi_D \simeq \phi(\vct x,t) = \frac{1}{2} \left( 1
+  - \tanh \left( \frac{3r(\vct x,t)}{\epsilon} \right) \right),
+  \label{eq:characteristic}
+\end{equation}
+where $\epsilon$ is the interface width and $r(\vct x,t)$ is the
+signed-distance function with respect to the boundary $\partial D$, which is
+taken to be negative inside $D$.
+
+The main difficulty with the diffuse-domain approach is the derivation of
+approximations for the boundary condition term BC.  \citet{Li09} give four
+approximations that are shown to converge asymptotically with first order in
+$\epsilon$ to the original equation when $\epsilon$ is decreased.  In the
+following we consider the approximation
+\begin{equation}
+  \text{BC} \simeq |\grad\phi| g.
+  \label{eq:bc1}
+\end{equation}
+If we combine the above approximations \eqref{eq:characteristic} and
+\eqref{eq:bc1}, we get a DDM1 equation for \eqref{eq:ddan},
+\begin{equation}
+  \div\left(\phi\grad u\right) - \phi u +  |\grad\phi| g = \phi f.
+  \label{eq:ddm1}
+\end{equation}
+
+\section{The method of matched asymptotic expansions}
+The following is a brief introduction to the method of matched asymptotic
+expansions, which is used to show that a given diffuse-domain approximation
+converges to the original problem when the interface width is decreased.  More
+details can be found in Paper~E and in \cite{Pego88}.
+
+Let $u$ be some diffuse-domain variable.  The asymptotic convergence of a given
+diffuse-domain approximation can be shown through expansions of the
+diffuse-domain variables in powers of the interface thickness $\epsilon$ in
+regions close to and far from the interface.  For example, the expansions of
+$u$ are
+\begin{align}
+  u(\vct x)        &= \sum_{k=0}^\infty \epsilon^k      u^{(k)}(\vct x), \\
+  \hat u(z,\vct s) &= \sum_{k=0}^\infty \epsilon^k \hat u^{(k)}(z,\vct s),
+\end{align}
+where $u(\vct x)$ and $\hat u(\vct s,z)$ denote the outer and inner expansions,
+respectively.  Here $z$ is a stretched variable,
+\begin{equation}
+  z = \frac{r(\vct x)}{\epsilon},
+\end{equation}
+where $r$ is the signed distance from the point $\vct x$ to $\partial D$ and is
+taken to be negative inside $D$.  Further, $z$ and $\vct s$ form a local
+coordinate system such that
+\begin{equation}
+  \vct x(\vct s,z) = \vct X(\vct s) + \epsilon z\vct n(\vct s),
+\end{equation}
+where $\vct X(\vct s)$ is a parametrisation of the interface, $\vct n(\vct s)$
+is the interface normal vector, and $z$ is a stretched variable.
+
+When the inner and outer expansions are found, they are matched in a region
+where both solutions are valid and where $\epsilon z = \bigo 1$, see
+\cref{fig:regions}.  The outer solution is then evaluated in the inner
+coordinates, which leads to a set of matching conditions that must hold when
+$\epsilon\to 0$.  If we consider $\epsilon$ to be fixed and let $z \to
+\pm\infty$, we get the following asymptotic matching conditions:
+\begin{equation}
+  \label{eq:match1}
+  \zlimpm \hat u^{(0)}(z,\vct s) = u^{(0)}(\vct s),
+\end{equation}
+and as $z \to \pm\infty$,
+\begin{align}
+  \label{eq:match2}
+  \hat u^{(1)}(z,\vct s) &= u^{(1)}(\vct s)
+    + z\ndot\grad u^{(0)}(\vct s) + \smallo 1, \\
+  \begin{split}
+    \hat u^{(2)}(z,\vct s) &= u^{(2)}(\vct s)
+      + z\ndot\grad u^{(1)}(\vct s) \\
+      &\quad + \frac{z^2}{2} (\ndot\grad)\grad u^{(0)}(\vct s)\cdot\vct n
+      + \smallo 1.
+    \label{eq:match3}

+
+We remark that the inner expansion is used to obtain the boundary condition on
+$\partial D$, and that the outer solution is used to obtain the sharp-interface
+equation inside the physical domain $D$.
+
+To show that a given DDM approximation converges with second order, one must
+show that the order-one term of the outer solution of the DDM equation is zero
+in $D$.  As an example, we consider the outer solution of the DDM1 equation
+\eqref{eq:ddm1}, which is
+\begin{equation}
+  \begin{split}
+    \lapl u^{(0)} - u^{(0)} &= f, \\
+    \lapl u^{(1)} - u^{(1)} &= 0, \\
+    \lapl u^{(k)} - u^{(k)} &= 0,\qquad k = 2,3,\dots.
+  \end{split}
+  \label{eq:ddm_outer}
+\end{equation}
+For the solution to be asymptotically second order, that is $u = u^{(0)}
++ \bigo{\epsilon^2}$, we must have that $u^{(0)}$ satisfies the original
+problem \eqref{eq:ddan} and that $u^{(1)}=0$.  Thus the inner expansion must
+yield a boundary condition for $u^{(1)}$ to enforce $u^{(1)}=0$.
+
+\section{Asymptotic analysis of the DDM1 and the DDM2}
+\label{sec:DDM2}
+In Paper~E we present the DDM2, which extends the DDM1 \eqref{eq:ddm1} with
+a high-order correction term,
+\begin{equation}
+  \div\left(\phi\grad u\right) - \phi u +  |\grad\phi| g
+    + r|\grad\phi|\left(f - \kappa  g - \lapls u + u\right) = \phi f.
+  \label{eq:ddm2}
+\end{equation}
+Here $r|\grad\phi|\left(f - \kappa  g - \lapls u + u\right)$ is the
+correction term, $\kappa$ is the curvature of the boundary $\partial D$, and
+$\lapls u$ is the surface Laplacian of $u$, which can be defined as
+\begin{equation}
+  \lapls u \equiv
+  \left( I - \vct n\otimes\vct n \right)
+        \div \left( I - \vct n\otimes\vct n \right)\grad u,
+\end{equation}
+where $I$ is the identity matrix and $\vct n$ is the normal vector.  The
+curvature can be calculated from the phase-field function
+\eqref{eq:characteristic} as
+\begin{equation}
+  \kappa = -\div\frac{\grad\phi}{|\grad\phi|}.
+\end{equation}
+
+In the following, we use the method of matched asymptotic expansions to show
+that the DDM1 \eqref{eq:ddm1} and the DDM2 \eqref{eq:ddm2} are both
+second-order approximations of \eqref{eq:ddan} in $\epsilon$.  First, it is
+easy to see that the outer expansions of both approximations are given by
+\eqref{eq:ddm_outer}.
+
+Next, we consider the inner expansion of the DDM2 \eqref{eq:ddm2}, which is
+\begin{multline}
+  \frac{1}{\epsilon^2}\left(\phi\hat u_z\right)_z
+  + \frac \kappa \epsilon \phi\hat u_z
+  + \phi\lapls \hat u
+  - \phi\hat u \\
+  - \frac 1 \epsilon \phi_z g
+  - z\phi_z\left(\hat u + \hat f - \kappa g - \lapls\hat u\right)
+  = \phi \hat f.
+  \label{eq:ddm_inner}
+\end{multline}
+We expand $\hat u(z,\vct s)$ in powers of $\epsilon$ and collect the lowest
+order terms,
+\begin{equation}
+  \left(\phi\hat u_z^{(0)}\right)_z = 0.
+\end{equation}
+If we integrate over all $z$, we get that $\hat u_z^{(0)} = 0$.  The next order
+terms of~\eqref{eq:ddm_inner} then give
+\begin{equation}
+  \left(\phi\hat u_z^{(1)}\right)_z = \phi_z g,
+\end{equation}
+and again we integrate, which gives that
+\begin{equation}
+  \phi\hat u_z^{(1)} = \phi g + C
+  \label{eq:uz1}
+\end{equation}
+where the constant $C$ must be zero, since $\lim_{z\to\infty}\phi(z) = 0$.  Now
+consider the limit $z\to-\infty$ and use the matching condition
+\eqref{eq:match2} to get
+\begin{equation}
+  \ndot\grad u^{(0)} = g.
+\end{equation}
+Thus $u^{(0)}$ satisfies the original problem at least to first order in
+$\epsilon$.  This shows that both DDM1 and DDM2 are first-order approximations
+of the sharp-interface problem.
+
+To obtain the result for the next order, we need to apply the derivative of
+the matching condition \eqref{eq:match3},
+\begin{equation}
+  \hat u_z^{(2)} = \ndot\grad u^{(1)}
+      + z (\ndot\grad)\grad u^{(0)}\cdot\vct n.
+  \label{eq:match3_z}
+\end{equation}
+Further, we use that $u^{(0)}$ satisfies
+\begin{equation}
+  \lapl u^{(0)} - u^{(0)} = f^{(0)},
+\end{equation}
+and that the Laplacian may be decomposed as
+\begin{equation}
+  \lapl u = (\ndot\grad)\grad u\cdot\vct n + \kappa\ndot\grad u + \lapls u,
+\end{equation}
+to get
+\begin{equation}
+  (\ndot\grad)\grad u^{(0)}\cdot\vct n
+    = u^{(0)} + f^{(0)} - \kappa g - \lapls u^{(0)}.
+  \label{eq:ngradun}
+\end{equation}
+Now insert \eqref{eq:ngradun} into \eqref{eq:match3_z} and use the matching
+condition \eqref{eq:match1} to obtain a modified matching condition,
+\begin{equation}
+  \hat u_z^{(2)} - z\left(\hat u^{(0)} + \hat f^{(0)}
+        - \kappa g - \lapls \hat u^{(0)}\right)
+  = \ndot\grad u^{(1)}.
+  \label{eq:match3_z2}
+\end{equation}
+
+We are now ready to consider the zeroth order terms,
+\begin{multline}
+  \label{eq:o1}
+  \left(\phi\hat u^{(2)}_z\right)_z
+  + \phi\kappa\hat u_z^{(1)}
+  + \phi\lapls \hat u^{(0)}
+  - \phi\hat u^{(0)} \\
+  - z\phi_z\left(\hat u^{(0)}
+      + \hat f^{(0)} - \kappa g - \lapls\hat u^{(0)}\right)
+  = \phi \hat f^{(0)}.
+\end{multline}
+The modified matching condition \eqref{eq:match3_z2} motivates that we subtract
+and add the term
+\[
+  \bigg(z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\bigg)_z
+\]
+to \eqref{eq:o1}, which gives
+\begin{multline}
+  \bigg(\phi\hat u_z^{(2)}
+    - z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\bigg)_z \\
+  + \bigg(z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\bigg)_z \\
+  + \phi\kappa\hat u_z^{(1)}
+  + \phi\lapls \hat u^{(0)}
+  - \phi\hat u^{(0)} \\
+  - z\phi_z\left(\hat u^{(0)}
+      + \hat f^{(0)} - \kappa g - \lapls\hat u^{(0)}\right)
+  = \phi \hat f^{(0)}.
+\end{multline}
+We expand the terms and use \eqref{eq:uz1},
+\begin{multline}
+  \bigg(\phi\hat u_z^{(2)}
+    - z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\bigg)_z \\
+  + \cancel{\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)} \\
+  + z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)_z \\
+  + \cancel{\phi\kappa g
+  + \phi\lapls \hat u^{(0)}
+  - \phi\hat u^{(0)}}
+  = \cancel{\phi \hat f^{(0)}},
+  \label{eq:o2}
+\end{multline}
+or
+\begin{multline}
+  \bigg(\phi\hat u_z^{(2)}
+    - z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\bigg)_z \\
+  + z\phi\left(\cancel{\hat u_z^{(0)}} + \hat f_z^{(0)}
+      - \cancel{(\kappa g)_z}
+      - \cancel{\lapls \hat u_z^{(0)}}\right) = 0.
+\end{multline}
+If we assume that $\hat f_z^{(0)}$, we get
+\begin{equation}
+  \bigg(\phi\hat u_z^{(2)}
+    - z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\bigg)_z = 0.
+  \label{eq:o3}
+\end{equation}
+Finally, we integrate the left-hand side and take the limit,
+\begin{align}
+  \nonumber
+  \eint{\bigg(\phi\hat u_z^{(2)}
+    &- z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+     - \lapls \hat u^{(0)}\right)\bigg)_z} \\
+  \nonumber
+  &= \ejmp{\phi\hat u_z^{(2)}
+    - z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)} \\
+  \nonumber
+  &= -\zlimm{\left(\hat u_z^{(2)}
+    - z\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\right)} \\
+  &= -\ndot\grad u^{(1)},
+\end{align}
+thus
+\begin{equation}
+  \ndot\grad u^{(1)} = 0.
+  \label{eq:ngradu1}
+\end{equation}
+Combined with \eqref{eq:ddm_outer}, this shows that $u^{(1)}=0$, and so DDM2
+converges asymptotically with second order to the original problem.
+
+The analysis above also holds for DDM1, except instead of \eqref{eq:o3} we get
+\begin{multline}
+  \bigg(\phi\hat u_z^{(2)}
+    - z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\bigg)_z \\
+  = - z\phi_z \left(\hat u^{(0)} + \hat
+        f^{(0)} - \kappa g - \lapls \hat u^{(0)}\right)
+  = - z\phi_z D,
+  \label{eq:o4}
+\end{multline}
+where $D$ is independent of $z$.  Now we use that
+\begin{equation}
+  \phi_z = -(3 \sech^2 3z)/2,
+\end{equation}
+which follows from the definition of the phase-field function
+\eqref{eq:characteristic}.  We integrate the right-hand side, which gives
+\begin{equation}
+  D\eint{z\phi_z} = -D\frac 3 2\eint{z\sech^2 3z} = 0.
+\end{equation}
+Thus DDM1 is also second order in $\epsilon$.
+
+The difference between the DDM1 and the DDM2 is therefore that the correction
+term with the DDM2 directly cancels the term on the right-hand side in
+\eqref{eq:o4}.  This should give an increase of accuracy, but the convergence
+order remains the same.
+
+The analysis for the corresponding Robin problem is essentially the same as the
+above.  In Paper~E, the DDM1 and DDM2 are compared for several elliptic
+problems with both Neumann and Robin boundary conditions.  The results of
+Paper~E show that the correction term in the DDM2 leads to an increase of
+accuracy and that both DDM1 and DDM2 converge with second-order accuracy.
+
+\section{Summary}
+In this chapter, we have given a brief introduction to the diffuse-domain
+method (DDM).  We considered a steady reaction-diffusion equation with Neumann
+boundary conditions \eqref{eq:ddan} and two DDM approximations:  DDM1
+\eqref{eq:ddm1} and DDM2 \eqref{eq:ddm2}.  The DDM2 is an extension of DDM1 by
+a high-order correction term, and was first derived in Paper~E.
+
+Next, we gave an outline of the method of matched asymptotic expansions, and we
+used it to show that both the DDM1 and the DDM2 converged asymptotically with
+second order in the diffuse-interface width to the original equation
+\eqref{eq:ddan}.  The analysis shows that the correction term in the DDM2 leads
+to a cancellation in the asymptotic expansions.  By doing the integration, we
+see that this cancellation is not necessary for obtaining the second order
+convergence.

+\section[Paper A]{Paper A:  Calculation of interface curvature with the
+  level-set method}
+Karl Yngve Lervåg.  Published in \emph{MekIT'11 - 6th National Conference on
+  Computational Mechanics, Trondheim}, 2011.  ISBN: 978-82-519-2798-7.
+
+In this paper I address a problem with the calculation of the interface
+curvature with the level-set method, cf.\ \cref{sec:curvature}.  The curvature
+can be calculated from the level-set function, $\phi$, as
+\begin{equation}
+  \kappa = \div\vct n = \div\frac{\grad\phi}{|\grad\phi|}.
+\end{equation}
+It is typically discretized by standard methods such as the second-order
+central-difference scheme (CD-2), and interpolated to the interface where
+needed \cite{Osher88,Kang00,Osher03}.  However, the level-set function as
+a signed-distance function will tend to have kinks where its gradient is
+discontinuous.  The standard methods may lead to large errors in the curvature
+close to these regions, which in turn may lead to errors in the surface tension
+force.
+
+The main contribution of this paper is a new curve-fitting discretization
+method (CFDM) for the curvature (see \cref{sec:curvature-curve-fitting}).  The
+method is based on the approach developed by \citet{Macklin06}.  It differs in
+that it uses a cubic Hermite spline parametrisation of the interface, and that
+the curvature values are calculated on the grid and then interpolated to the
+interface as opposed to using a localised grid centred at the interface as in
+\cite{Macklin06}.

+\end{figure}
+
+The CFDM is tested and compared with the CD-2 for two test cases, and it is
+shown to yield better results in both cases.  \Cref{fig:A1} shows one of these
+results, where the calculated curvature values are compared.  In the example,
+a cylindrical drop impacts on a liquid film.  The figure shows that the CD-2
+leads to large errors in the curvature calculations in the kink regions, that
+is, the red and dark blue regions in \cref{fig:A1a} near the liquid film.
+These errors are not present with the new method, cf.\ \cref{fig:A1b}.
+

+\section[Paper B]{Paper B:  Curvature calculations for the level-set method}
+Karl Yngve Lervåg and Åsmund Ervik.  Published in \emph{ENUMATH 2011}
+proceedings volume, Springer, 2013.  ISBN: 978-3642331336.
+
+This paper is a continuation of Paper A.  The main contribution in this paper
+is a comparison of different methods for calculating the curvature in a robust
+manner with the level-set method in the kink regions.  In particular, the
+CFDM\footnote{The method is called LM in the paper.  Here CFDM is used, in
+  order to be consistent with the rest of the thesis.} that was presented in
+Paper A is compared with Macklin and Lowengrub's method (MLM)~\cite{Macklin06}.
+In addition, the method is compared with the second-order central-difference
+scheme (CD-2) and the more recent method presented by \citet{Salac08}, here
+called Salac and Lu's method (SLM).
+
+The main result in the paper is shown in \cref{fig:B1}, which shows
+a comparison of the methods for a case where two drops collide in a 2D shear
+flow.  In particular, it shows snapshots of the evolution of the interfaces and
+the curvature at times $t=\SI{2.30}{s}$, $t=\SI{2.75}{s}$, and
+$t=\SI{3.10}{s}$.  The results show that all of the improved methods, that is
+MLM, CFDM, and SLM, handle the kink region in a more reliable manner than CD-2.
+The reason that the result with MLM differs from those with CFDM and SLM might
+be that it uses a localised grid centred at the interface to calculate the
+curvature, which means that it does not need to use interpolation of the
+curvature from the grid to the interface.  Note that the difference is mainly
+that the MLM results in slightly earlier coalescence in the given case.

+\section[Paper C]{Paper C:  Calculation of the interface curvature and normal
+  vector with the level-set method}
+Karl Yngve Lervåg, Bernhard Müller, and Svend Tollak Munkejord.  Published in
+Computers and Fluids, volume 84 (2013), 218--230.
+
+Paper A presented the curve-fitting discretization method (CFDM) for the
+calculation of the curvature with the level-set method.  The method was
+designed to be robust in the calculation of the curvature in kink regions, that
+is regions where the gradient of the level-set function is not smooth.  This
+paper presents the details of the CFDM and applies it to the calculation of
+both the curvature and the normal vector.
+
+In the paper we compare the CFDM with the second-order central-difference
+scheme (CD-2) for several test cases.  In the first case, we consider the
+curvature calculations for a nontrivial geometry that includes some kink
+regions.  This is a static test case with no flow, and the results show that
+the CD-2 leads to large errors for the curvature calculations in areas close to
+kink regions and that these errors are not present with the CFDM.
+
+In the following two cases, we consider the collision of two drops in a 2D
+shear flow and in an axisymmetric flow.  These cases show that the errors in
+the curvature calculations in the kink regions with the CD-2 lead to errors in
+the pressure that prevents coalescence.  These errors are prevented with the
+CFDM.  The curvature and the evolution of the interfaces for the axisymmetric
+case are shown in \cref{fig:C1,fig:C2}.  As in the earlier results of Papers
+A and B, the figures show that the errors in the curvature calculation with
+CD-2 prevent coalescence, in this case leading to a slower coalescence process.

+\section[Paper D]{Paper D:  A robust method for calculating interface curvature
+  and normal vectors using an extracted local level set}
+Åsmund Ervik, Karl Yngve Lervåg, and Svend Tollak Munkejord.  Submitted to
+Journal of Computational Physics, 2013.
+
+In this paper we present an alternative method for the calculation of the
+curvature and the normal vector of an interface with the level-set method in
+kink regions, hereafter called the local level-set extraction (LOLEX) method.
+The method is based on a method presented by \citet{Salac08} (SLM), who handle
+the kink region by extracting different bodies of a domain into separate
+level-set functions.  This procedure removes most of the kink regions, but it
+does not handle kink regions that are due to complex interfaces of single
+bodies.  Our method extends the SLM by making it local.  That is, we only
+consider the local area around the point for which we are calculating the
+curvature or the normal vector.  This leads to a method that is more generally
+applicable, as shown in \cref{fig:D1}.  The figure shows a comparison between
+the LOLEX method, the SLM, and the standard central differences (CD-2).  CD-2
+leads to curvature spikes at the kink regions, as explained in
+\cref{sec:curvature}.  The SLM gives a better result for the kink regions
+around the rightmost disc.  However, since the other two discs are connected to
+each other and to the film, they are considered to be the same body and are
+extracted into the same level-set function.  Several kink regions are therefore
+not removed.  Since the LOLEX method only considers the local area, as
+explained in \cref{sec:lolex}, it is able to handle all the kink regions in
+a robust manner.

+    is disjoint.  The color indicates the curvature; white is zero, blue is
+    negative and red is positive.}
+  \label{fig:D1}
+\end{figure}
+
+The LOLEX method has proven to be a good alternative to the CFDM presented in
+Paper A.  Its main advantages are that it does not rely on complex algorithms
+as used in the CFDM or by \citet{Macklin06}, and that the method easily extends
+to 3D as demonstrated in the paper in Section~4.4.
+
+In the previous papers A--C, we used the DP1 projection method by
+\citet{Hansen05}.  In this paper we instead used the more standard Chorin
+projection method.  These methods differ in that the DP1 assumes
+\begin{equation}
+  \div\left(\pdt{\vct u}\right) = 0.
+\end{equation}
+When compared with the Chorin method, this assumption becomes equivalent to
+assuming that $\div\vct u^{n} = 0$ in \eqref{eq:PoissonChorin}.  That is, the
+DP1 assumes that the initial velocity field is divergence free.  We have found
+that the DP1 works well in most cases, but that it is less robust than the
+Chorin method.  In particular, the Chorin method is not equally affected by
+errors in the curvature calculations in kink regions.  In other words, the
+difference between using a standard discretization and an improved
+discretization of the curvature is smaller with the Chorin method than with the
+DP1.
+
+The LOLEX method is used for several test cases and compared with CD-2.  The
+results indicate that even though we use the Chorin projection method, the
+LOLEX method outperforms CD-2 in all cases.  Further, the results agree well
+with experiments, except for time instants, as shown in \cref{fig:D2}.  The
+exact reason why the time instants do not match is not known, but one reason
+may be that the initial condition of the numerical simulation did not match the
+corresponding state of the experiment.

+    from~\cite{Zhao11}, Copyright (2011), with permission from Elsevier.}
+  \label{fig:D2}
+\end{figure}
+
+When we study the drop-film collision processes, an important consequence of
+the error in the curvature calculation is a loss of kinetic energy.  This can
+be seen in \cref{fig:D3}, which compares the LOLEX method with CD-2 at two
+different stages of the collision process.  The figure also compares two
+different frequencies of reinitialization of the level-set function:  Every
+7 time steps ((a) and (c)) and every single time step ((b) and (d)).  The
+figure shows that the error in the curvature calculation with CD-2 leads to
+a shorter neck, as seen in \cref{fig:D3}, (c) and (d).  The error is larger for
+the higher frequency of reinitialization.  The results indicate that CD-2 leads
+to a loss of kinetic energy during the collision process when compared with the
+LOLEX method.  The LOLEX method is not significantly affected by the amount of
+reinitialization, and the kink region does not affect the curvature
+calculation, cf.\ \cref{sec:lolex}.  Thus the pressure field is more sensible,
+as seen in \cref{fig:D3} (a) and (b).  Finally, we remark that some authors
+have noted \cite{Blanchette06} that the height of the neck and the dynamics of
+the capillary waves are important factors for the partial coalescence
+mechanism, which implies that the correct calculation of the curvature is
+important to capture the correct physical behavior.

+\section[Paper E]{Paper E:  Towards a second-order diffuse-domain approach for
+  solving PDEs in complex geometries}
+Karl Yngve Lervåg and John Lowengrub.  Submitted to Communications in Math.
+Sciences, 2013.
+
+\citet{Li09} developed a diffuse-domain method for solving partial-differential
+equations (PDEs) inside complex, dynamic geometries with Dirichlet, Neumann,
+and Robin boundary conditions.  This method is in the following referred to as
+DDM1.  They use the diffuse-domain approach~\cite{Kockelkoren03}, where the
+geometry is represented implicitly and the sharp boundary is replaced by
+a diffuse layer with a fixed interface width.  The original governing equations
+are then reformulated on a larger, regular domain and the boundary conditions
+are incorporated via singular source terms.  The method of matched asymptotic
+expansions is used to show that the reformulated problem converges
+asymptotically to the original problem.
+
+In the present paper, we use the method of matched asymptotic expansions to
+extend the DDM1 with include a high-order correction term in the diffuse
+formulation, cf.\ \cref{sec:DDM2}.  The extension is derived for elliptic
+problems with Neumann and Robin boundary conditions, where the correction term
+is shown to yield an asymptotically second-order accurate approximation of the
+original problem.  The new method is referred to as the DDM2.
+
+The DDM1 and DDM2 are compared for a selection of test problems.  The resulting
+equations were discretized by standard second-order central-difference schemes
+on uniform grids, and solved by a multigrid method.  A red-black Gauss-Seidel
+type iterative method was used as a smoother, see \cite{Wise07}.
+
+In addition to the comparison of DDM1 and DDM2, we compared two different
+approximations of the boundary conditions.  These correspond to different
+diffuse-interface surface delta functions, and for the Neumann boundary
+conditions they are
+\begin{equation}
+  \text{BC1} = |\grad\phi| g,
+\end{equation}
+and
+\begin{equation}
+  \text{BC2} = \epsilon|\grad\phi|^2 g.
+\end{equation}
+The approximations are similar for the Robin boundary condition, although here
+it was found that only BC1 resulted in a valid asymptotically second-order
+accurate DDM2.
+
+Our results show that the global accuracy and convergence of DDM2 is better
+than DDM1, however both methods perform well and the global convergence rate is
+around two for each.  The error was measured as the L$_2$ norm of the
+difference between an analytic solution and the solution $u_\epsilon$ for
+a given interface width, $\epsilon$.
+
+\Cref{fig:E1,fig:E2} show two of the results, the first one with the Neumann
+boundary conditions and the second with the Robin boundary condition.  The
+results indicate that DDM2 performs slightly better than DDM1.  They also show
+that the approximation BC1 gives more accurate results than BC2.  In
+particular, we found that with BC2 we needed much finer grids to obtain
+convergence for a given $\epsilon$.  For the smallest values of $\epsilon$ we
+were not able to refine the grids enough to obtain valid results.

+\chapter{Conclusions and outlook}
+\label{chap:conclusions}
+This thesis has considered two different problems:  The discretization of
+interface curvature and normal vectors with the level-set method and
+a diffuse-domain approach for solving partial-differential equations (PDEs) in
+complex domains.  In the following, some general concluding remarks and
+recommendations for further work are given.
+
+\section*{Conclusions}
+The first part of the thesis considered the modelling of incompressible
+two-phase flow.  The main motivation was to study two-phase flow phenomena that
+are relevant for compact heat exchangers, such as drop-drop and drop-film
+collisions.  In particular, the thesis addressed a challenge with the
+calculation of interface curvature and normal vectors with the level-set
+method.  Two methods were presented to handle the discretization in the kink
+regions: A curve-fitting discretization method (CFDM) and a local level-set
+extraction (LOLEX) method.  Both methods were shown to be robust in the kink
+regions, where the standard central-difference scheme (CD-2) fails.  Of these
+methods, the LOLEX method is the preferred method, because it relies on a less
+complicated algorithm that easily extends to 3D.
+
+CD-2 and the LOLEX method were used for simulations of drop-film collisions
+that were compared with experiments.  The results showed that CD-2 leads to
+errors in the curvature that cause unphysical pressure spikes during the
+coalescence.  The errors are shown to lead to a dissipation of kinetic energy
+during the collision and to a slower coalescence process.  The LOLEX method was
+shown to prevent these unphysical pressure spikes, and to produce to more
+accurate results.
+
+The second part of the thesis considered the diffuse-domain approach for
+solving PDEs in complex domains.  The main contribution, presented in Paper~E,
+was the derivation of an asymptotically second-order diffuse-domain method
+(DDM2) for solving elliptic problems in complex geometries with Neumann and
+Robin boundary conditions.  The new method is an extension by a high-order
+correction term of the method presented in \cite{Li09}, here called DDM1.  The
+DDM1 and DDM2 were compared, and the results indicated that the DDM2 was
+slightly better than the DDM1.
+
+The thesis has expanded on the results of Paper~E with a new asymptotic
+analysis that shows that DDM1 is in fact also asymptotically second order.
+This analysis helps to explain why the performance of DDM2 presented in Paper~E
+is only slightly better than that of DDM1.  As such, the new analysis leads to
+a better understanding of the DDM1 and the DDM2.
+
+\section*{Outlook}
+The following gives an outline of some possibilities for future work.
+\begin{itemize}
+  \item A natural continuation of this work is to perform more in-depth
+    comparisons of simulations with experiments for the drop-film collision
+    phenomenon that was started in Paper~D.  In addition, it would be
+    interesting to study other two-phase flow phenomena that are relevant for
+    heat-exchanger processes, for instance drop-drop collisions or flow across
+    tube bundles.  The latter requires the treatment of more complex boundaries,
+    which can be handled either with the diffuse-domain method or other methods
+    from the literature.
+  \item Paper~C gave a short comparison of the standard discretization method
+    (CD-2), the direction-difference scheme (DDS), and the curve-fitting
+    discretization scheme (CFDM) applied to the calculation of the normal
+    vectors.  The results showed that the CD-2 leads to inaccurate results in
+    the kink regions.  The DDS gives robust and accurate results in most cases,
+    but an example is given where only the CFDM yields an accurate result.
+    However, the impact of inaccurate calculations of the normal vector should
+    be investigated in more detail.  The normal vector is used both for the
+    solution of the level-set equations \eqref{eq:ls_adeq},
+    \eqref{eq:ls_velextr}, and \eqref{eq:ls_reinit}, and for the calculation of
+    the interface jumps \eqref{eq:jump_pressure} and \eqref{eq:jumptens}, so
+    one can expect that large errors in the calculation of the normal vector
+    may lead to large errors in the numerical solution.  This warrants
+    a further study.
+  \item Mass and heat transfer are obviously an important part of the
+    heat-exchanger processes.  The models that have been used in this thesis
+    should therefore be expanded with additional models for heat transfer and
+    mass transfer to enable the simulation of more relevant phenomena.
+  \item The DDM2 was only derived for problems with Robin and Neumann boundary
+    conditions.  If possible, it should be extended to also work with Dirichlet
+    boundary conditions.
+  \item As explained in Paper~E, we found that we were unable to solve the
+    discrete system of equations when the surface Laplacian part of the
+    correction term for the DDM2 was included.  A further investigation of this
+    problem should be done, and stable numerical methods to solve the full DDM2
+    equations should be developed.
+  \item The diffuse-domain approach is a promising method for solving problems
+    in complex and confined geometries with standard tools and methods.
+    \citet{Aland10} provide a diffuse-domain formulation of the Navier-Stokes
+    Cahn-Hilliard equations for incompressible two-phase flow and use it to
+    compute two-phase flow in both complex and confined geometries.  However,
+    they do not provide an asymptotic analysis of the reformulated equations to
+    show that the system converges.  Such an analysis would be interesting, in
+    particular to verify that the equations do converge to the original problem
+    when the interface width is decreased.
+  \item Finally, it would be interesting to develop a second-order
+    diffuse-domain formulation for the incompressible Navier-Stokes equations.
+    A starting point would be to use the results and techniques from this
+    thesis and Paper~E.

+\chapter{Introduction}
+This thesis considers the mathematical modelling and numerical computation of
+two-phase flows.  It focuses on developing more robust numerical methods to
+calculate the curvature and the normal vector of the interface between the two
+phases.  In addition it considers a diffuse-domain method for solving partial
+differential equations in complex geometries, and it derives an asymptotically
+second-order method for elliptic problems.
+
+\section{Background and motivation}
+Two-phase flows are particular examples of multiphase flows of gas and liquid
+with an interface that separates the two phases.  In the pedantic sense,
+two-phase flow is flow of a single fluid that occurs as two different phases,
+for example steam and water.  However, it is common to be more general, and in
+this thesis we use the term two-phase flow also for immiscible mixtures of
+different fluids, such as water and oil.
+
+Two-phase flows are crucial to a large amount of processes, both in nature and
+in industry.  Examples range from weather phenomena, such as rain drops falling
+through air, to industrial processes, for instance the separation of water from
+oil.  In general, multiphase flow phenomena influence any process where liquids
+and gases are involved.  In the oil and gas industry, most processes are
+two-phase or multiphase flow processes.  Needless to say, the understanding of
+these phenomena is fundamental in the development of new or improved processes.
+
+Consider the international trade of liquefied natural gas (LNG), which is
+a particular branch of the oil and gas industry that has undergone an
+exceptional growth in the last decades.  There is a strong focus both in Norway
+and internationally on producing LNG on large floaters
+(FLNG)\footnote{FLNG facilities do not yet exist, although a facility is under
+  development by Royal Dutch Shell~\cite{Prelude1}.  The construction of this
+  facility was started in 2012, and the first drilling is stated to commence in
+  2013~\cite{Prelude2}.}.  There are a number of both environmental and
+economic advantages of such FLNG facilities.  In particular, FLNG facilities
+would remove the need of long pipelines from the gas fields to the shore, there
+would be no requirement for compression units to pump the gas to the shore, and
+one would not need to construct onshore production facilities.  This would
+significantly reduce the environmental footprint, and would help preserve
+marine and coastal environments.  Since an FLNG facility can be moved to a new
+location when a field has been depleted, it would make it economically viable
+to open up new business opportunities to develop offshore gas fields that would
+otherwise remain stranded.
+
+Moving the LNG production to an offshore facility presents a demanding set of
+challenges.  A particular challenge is that the elements of a conventional LNG
+facility need to fit into an area roughly one quarter the original size.  Heat
+exchangers are among the main challenges in the design and operation of LNG
+plants \cite{Hesselgreaves01}.  Compact and efficient heat exchangers are
+needed to obtain an energy efficient plant with low emissions.  More optimized
+designs require more accurate tools for design and operation.  Such tools can
+only come as a result of an improved physical understanding of the complex
+two-phase flows occurring in the heat exchangers.  This can be achieved by more
+detailed mathematical modelling, together with dedicated laboratory
+observations, cf.\ \cite{Olsen07}.
+
+\section{Overview of methods for two-phase flow simulations}
+In the following, a brief overview is given of different methods for modelling
+two-phase flows where the interface location is known.  In particular, we focus
+on methods that handle the interface evolution.  For more in-depth reviews, see
+for instance \cite{Cristini04,Scardovelli99,Sethian03}.
+
+Interface propagation methods comprise a range of methods that are often
+categorised as either front tracking or front capturing.  Front-tracking
+methods use Lagrangian particles to track the interface
+explicitly~\cite{Tryggvason01}, while front-capturing methods use an Eulerian
+approach to capture the interface implicitly.  Examples of the latter are
+volume-of-fluid methods~\cite{Scardovelli99,Tryggvason11}, phase-field
+methods~\cite{Anderson98,Jacqmin99,Lowengrub98}, and level-set
+methods~\cite{Osher03}.
+
+The main advantages of front-tracking methods are their inherent accuracy and
+that topological changes do not occur without explicit action.  Hence,
+unphysical numerical reconnection does not occur.  This means that if front
+tracking is used for the simulations of two drops that collide, these drops
+will not coalesce due to numerical reconnection or merging.  However, the
+handling of topological changes are challenging, in particular in three
+dimensions~\cite{Shin02}.  Also, there are some issues of numerical
+instabilities, as discussed by \citet{Sethian85} and \citet{Osher88}.
+
+The volume-of-fluid method utilizes a volume-fraction function whose values
+represent the characteristic function of one of the fluid domains.  Its values
+are zero or one, except in those cells cut by the interface.  A considerable
+advantage of the volume-of-fluid method is that it conserves the mass of both
+fluids well.  However, the reconstruction of the interface from volume
+fractions is not simple, and computation of geometric quantities such as the
+interface curvature is not straightforward.  Also, spurious bubbles and drops
+may be created, cf.\ \cite{Lafaurie94}.
+
+The phase-field methods treat the interface in a diffuse manner, where the
+fluid properties, such as density and viscosity, change rapidly but smoothly
+across the interface.  These methods typically solve the coupled
+Cahn-Hilliard/Navier-Stokes equations, where the Cahn-Hilliard equation is
+based on the free energy of an interface~\cite{Cahn57}.  Through this energy
+formulation, one can model more advanced interface physics such as van der
+Waals interactions, electrostatic forces, and fluids with varying
+miscibilities.  However, the phase-field methods require that one resolves very
+small length scales at the interfaces.  This poses a severe restriction on the
+applicability of phase-field methods for two-phase flow, where the length
+scales of the flow are generally much larger than those of the interface.
+
+In this thesis, we have used the level-set method~\cite{Osher88}, which
+implicitly captures the interface as an isocontour of a function defined in the
+entire domain.  The main motivation of this choice is both that the level-set
+method handles topological changes of evolving interfaces automatically,
+cf.~\citet{Sethian03}, and that it is relatively straightforward to implement.
+
+It should be noted that the automatic handling of topological changes is not
+based on physical principles.  For instance, when two interfaces approach each
+other and their distance becomes less than the spacing of the grid, the
+level-set method can no longer resolve both interfaces and so they are merged.
+An important consequence is that the level-set method does not model the
+physics involved in the coalescence process, and in particular in the smaller
+scales of the film-drainage process.  This process involves a wide range of
+length scales, varying from the nanometer scale where van der Waals force are
+active to the length scales of the external flow.  Some effort has been made to
+include the effects of the smaller scales in front-capturing methods,
+cf.~\cite{Nobari96,Tryggvason10}.  Recently, \citet{Kwakkel13} presented
+a level-set/volume-of-fluid method that is coupled with a film-drainage model
+that predicts if and when two colliding droplets will coalesce.  To prevent the
+numerical coalescence, each droplet has its own locally defined level-set
+function.
+
+The level-set method has been used to model several diverse phenomena,
+such as tumour growth~\cite{Macklin06,Macklin05,Macklin08}, propagation of
+wildland fire~\cite{Mallet09}, and computer RAM production~\cite{Melicher08}.
+For a good and thorough introduction to the level-set method, see
+\cite{Osher03}.
+
+A weakness of the level-set method is that it does not conserve the mass of the
+two fluids, in particular in areas of low resolution and/or high curvature.
+Different approaches have been developed to overcome this disadvantage, for
+example the conservative level-set method~\cite{Olsson05,Olsson07}, the
+particle level-set method~\cite{Enright02}, or the coupled
+level-set/volume-of-fluid method~\cite{Sussman00}.
+
+When we use the level-set method to capture the interface for immiscible and
+incompressible two-phase flow simulations, there will be a sharp change in the
+density and viscosity across the interface.  In this thesis we use the
+ghost-fluid method~\cite{Fedkiw99}, which is a sharp-interface method where the
+jumps are included in the spatial discretizations in a sharp manner.  An
+alternative method is the continuous surface-force method introduced by
+\citet{Brackbill92}, where the density and the viscosity are smeared out across
+the interface through a smoothed Heaviside function.
+
+\clearpage
+\section{Goal and contribution of the present thesis}
+The main goal of the PhD project has been to develop fundamental knowledge of
+two-phase flow phenomenon that are relevant for compact heat exchangers.
+
+In order to do detailed theoretical studies of phenomena that are relevant for
+compact heat exchangers, we need to consider two-phase flows with mass and heat
+transfer in confined and complex geometries.  One such relevant phenomenon is
+the drop-film collision process \cite{Zhao09}.  Even when restricted to
+isothermal and immiscible flows, this simple phenomenon remains a challenge.
+When the level-set method is used to capture the interface, one must be
+particularly careful about how one calculates the interface curvature and
+normal vector.  For instance, when two drops are in near collision there is
+a kink region in the level-set function between the drops, where the gradient
+is discontinuous, see \cref{fig:curvature-problem}.  This discontinuity may
+lead to large errors in the curvature and the normal vector if it is not taken
+into account in the discretization stencils.

+
+As a step towards computing two-phase flow simulations in confined geometries,
+the thesis has considered the diffuse-domain method~\cite{Li09}.  This is
+a method where partial-differential equations in complex domains are extended
+into larger, regular domains with the use of diffuse approximations of the
+physical boundaries.  The approximations converge asymptotically to the
+original problem when the width of the diffuse boundary is reduced.  With this
+method one can use standard numerical methods to solve equations that
+incorporate complex boundaries.
+
+The main contributions of the present thesis are two new methods to calculate
+the curvature and normal vector in a robust manner with the level-set method.
+These methods are shown to yield more accurate calculations of drop-film and
+drop-drop collisions.  The methods are compared with standard methods and with
+other methods from the literature.
+
+In addition, the thesis presents an extension of a diffuse-domain method by
+a high-order correction term for the solution of elliptic problems in complex
+geometries.  New analysis provided in the thesis improves the understanding of
+the diffuse-domain method, and the derived method is shown to be more accurate
+than the existing diffuse-domain method.
+
+\section{Outline of the thesis}
+The thesis is organised as follows: \Cref{chap:two-phase-flow} gives a brief
+overview of the derivation of the governing equations for two-phase flow.  It
+includes a consideration of the fluid-fluid interface conditions and the
+derivation of a simplified jump tensor for the viscous term at the interface.
+
+\Cref{chap:numerical-methods} gives a detailed description of the numerical
+methods that are used to solve the two-phase flow equations.  In particular, it
+describes the level-set method, which is used to capture the interfaces,
+projection methods that are used to solve the Navier-Stokes equations, and the
+spatial and temporal discretization schemes.  At the end of the chapter, an
+overview of the novel discretization methods for the curvature and the normal
+vector is given.
+
+\Cref{chap:diffuse-domain} gives a short introduction to the diffuse-domain
+method for an elliptic problem with Neumann boundary conditions.  It introduces
+the high-order correction term, and shows that the new method converges
+asymptotically with second-order to the original problem.  The chapter presents
+new analysis that shows that the correction term is not necessary for
+second-order convergence.
+
+In \cref{chap:contributions} the main results of the contributed papers A--E
+are summarized, and the author's contributions are highlighted.  Finally,
+\cref{chap:conclusions} gives concluding remarks and provides an outlook for
+future work.
+
+Full-text versions of the research papers A--E are provided in the Appendices
+at the end of the thesis.

+\chapter{Governing equations for two-phase flow}
+\label{chap:two-phase-flow}
+In this chapter we will give a brief overview of the derivation of the
+governing equations for two-phase flow.  We begin with a consideration of the
+Navier-Stokes equations for single-phase flow.  We then introduce a singular
+surface-force term and derive the Navier-Stokes equations for two-phase flow.
+Finally, we use the Navier-Stokes equations for two-phase flow to derive jump
+conditions at the interface between the phases.
+
+\section{The Navier-Stokes equations for single-phase flow}
+The following is a brief derivation of the Navier-Stokes equations for
+single-phase flows.  For a more thorough derivation of these equations, see for
+instance \citet[§4 and §5]{Aris89} or \citet[Chapter~4]{White03}.
+
+We consider a single-phase, viscous flow in some domain $\Omega$ with boundary
+$\partial\Omega$.  When temperature effects are neglected the flow is described
+by the Cauchy equation
+\begin{equation}
+  \label{eq:cauchy_equation}
+  \rho\left(\cd{\vct u}\right) = \div\tenstr+\rho\vct f,
+\end{equation}
+and the mass conservation equation,
+\begin{equation}
+  \label{eq:cons_of_mass}
+  \pdt\rho + \div(\rho\vct u) = 0.
+\end{equation}
+Here $\rho$ is the fluid density, $\vct u$ is the flow velocity, $t$ is time,
+$\tenstr$ is the stress tensor, $\vct f$ denotes body forces, and $\del$ is
+used to denote the gradient and divergence operators.  The stress tensor for
+Newtonian fluids with zero bulk viscosity is
+\begin{equation}
+  \tenstr = -p\tenI + 2\mu\tenD - \frac 2 3\mu (\trace\tenD) \tenI,
+  \label{eq:viscous_stress_tensor}
+\end{equation}
+where $p$ is the pressure, $\tenI$ is the identity tensor, $\mu$ is the dynamic
+viscosity, and $\trace\tenD$ denotes the trace of the strain-rate tensor
+$\tenD$,
+\begin{equation}
+  \tenD = \frac{1}{2}\left( \grad\vct u + (\grad\vct u)^T \right).
+  \label{eq:deformation_tensor}
+\end{equation}
+For incompressible flow, the mass-conservation equation reduces to
+\begin{equation}
+  \label{eq:navier-stokes-1}
+  \div\vct u = 0,
+\end{equation}
+that is, the velocity field must be divergence free.  If we further assume that
+the viscosity is constant, then it follows that the divergence of the stress
+tensor reduces to
+\begin{equation}
+  \label{eq:stress_tensor}
+  \div\tenstr = -\grad p + \mu\lapl\vct u,
+\end{equation}
+and so the Cauchy equation \eqref{eq:cauchy_equation} becomes
+\begin{equation}
+  \rho\left(\cd{\vct u}\right) = -\grad p + \mu\lapl\vct u + \rho\vct f.
+  \label{eq:navier-stokes-2}
+\end{equation}
+Equations \eqref{eq:navier-stokes-1} and \eqref{eq:navier-stokes-2} are the
+incompressible Navier-Stokes equations for single-phase flow with constant
+viscosity.
+
+\section{The Navier-Stokes equations for two-phase flow}
+We now consider an immiscible two-phase flow of two Newtonian fluids, each with
+its own viscosity and density.  We let $\Omega_1$ and $\Omega_2$ denote the
+domains occupied by fluid 1 and fluid 2, respectively, and let the interface
+between the fluids be denoted by $\Gamma$.  Then $\Omega
+= \Omega_1\cup\Omega_2$ and $\partial\Omega
+= (\partial\Omega_1\cup\partial\Omega_2)\setminus\Gamma$ are the fluid domain
+and its boundary, respectively.  See \cref{fig:domain} for an illustration of
+a two-phase flow domain.

+  \caption{An illustration of a two-phase flow domain.  The interface $\Gamma$
+    separates the two phases $\Omega_1$ and $\Omega_2$.}
+  \label{fig:domain}
+\end{figure}
+
+The extension of the single-phase model to account for two fluids can be made
+by adding a singular surface-force term to represent the effects of surface
+tension between the fluids.  We assume that the surface tension is constant, in
+which case the singular surface force can be defined as
+\begin{equation}
+  \funssf(\vct x,t)
+  = \int_{\Gamma}\sigma\kappa\vct n\delta(\vct x - \vct x_I(\vct s))\dif\vct s,
+  \label{eq:ssf}
+\end{equation}
+where $\sigma$ is the surface tension, $\kappa$ is the local curvature, $\vct
+n$ is the normal vector, $\delta$ is the Dirac delta function, and $\vct
+x_I(\vct s)$ is a parametrisation of the interface.  Thus the Navier-Stokes
+equations for immiscible and incompressible two-phase flow are
+\begin{align}
+  \label{eq:ns1}
+  \div\vct u &= 0, \\
+  \label{eq:ns2}
+  \rho\left(\cd{\vct u}\right) &= -\grad p + \mu\lapl\vct u
+    + \rho\vct f + \funssf.
+\end{align}
+
+\section{Fluid-fluid interface conditions}
+The surface-tension force and the jump in viscosity and density across the
+interface $\Gamma$ lead to a set of interface conditions that must be satisfied
+along the interface $\Gamma$.  The following is a brief derivation of these
+conditions.
+
+First, we only consider flows where there is no mass transfer, which implies
+that
+\begin{equation}
+  \jmp{\vct u}\cdot\vct n = 0,
+\end{equation}
+where $\jmp{\cdot}$ denotes the jump at the interface, for instance $\jmp{\mu}
+= \mu_2 - \mu_1$.  Further, for viscous flows there is no slip at the
+interface, and thus the tangential velocity component of the two fluids must be
+equal at the interface,
+\begin{equation}
+  \jmp{\vct u}\cdot\vct t = 0.
+\end{equation}
+It follows that
+\begin{align}
+  \label{eq:jmpu}
+  \jmp{\vct u} &= 0, \\
+  \label{eq:jmpJut}
+  \jmp{\grad \vct u}\cdot\vct t &= 0.
+\end{align}
+The latter is a direct consequence of the former.  Both fluids are
+incompressible, which gives the trivial identity $\jmp{\div\vct u} = 0$.  If we
+use the identity
+\begin{equation}
+  \div\vct u
+    = \vct n\cdot\grad\vct u\cdot\vct n + \vct t\cdot\grad\vct u\cdot\vct t
+  \label{eq:divuident}
+\end{equation}
+together with \eqref{eq:jmpJut} we get
+\begin{equation}
+  \vct n\cdot\jmp{\grad\vct u}\cdot\vct n = 0,
+  \label{eq:jmpngradun}
+\end{equation}
+which means that the normal component of the normal derivative of the velocity
+field is continuous across the interface.  Note that in \eqref{eq:divuident}
+and in similar expressions in the following, the nabla operator is only applied
+to $\vct u$, not the normal and tangential vectors that follow.

+  \end{tikzpicture}
+  \caption{A sketch of the control volume $\Omega_\epsilon$ that covers the
+    interface, $\Gamma$.}
+  \label{fig:domain_omega_epsilon}
+\end{figure}%
+Next, we consider the conservation of momentum.  We define a control volume
+\begin{equation}
+  \Omega_{\epsilon} = \set{\vct x \in \Omega}{\min_{\vct x_I \in \Gamma}|\vct
+    x - \vct x_I| \leq \epsilon},
+\end{equation}
+where $\epsilon > 0$, see \cref{fig:domain_omega_epsilon}.  We then integrate
+the Cauchy equation \eqref{eq:cauchy_equation} with the added singular
+surface-force term over the domain~$\Omega_\epsilon$,
+\begin{multline}
+  \intoepdx{\rho\td{\vct u}}
+    = \intoepdx{\div\tenstr} + \intoepdx{\rho\vct f} \\
+      + \intoepdx{ \int_{\Gamma}\sigma\kappa\vct n\delta(\vct x - \vct
+        x_I(\vct s))\dif\vct s}.
+\end{multline}
+Here $\tdi{\vct u} = \partial\vct u/\partial t + \vct u\cdot\grad\vct u$
+denotes the convective derivative.  Now we apply the Gauss theorem and change
+the order of integration in the last term to obtain
+\begin{equation}
+  \intoepdx{\rho\td{\vct u}} = \intdoepds{\tenstr\cdot\vct n}
+    + \intoepdx{\rho\vct f} + \int_\Gamma\sigma\kappa\vct n\dif\vct s.
+\end{equation}
+If we let $\epsilon$ go to zero, the left-hand side and the second term on the
+right-hand side vanish, and we get
+\begin{equation}
+  0 = \int_\Gamma\left( \jmp{\tenstr}\cdot\vct n + \sigma\kappa\vct
+    n \right)\dif s.
+  \label{eq:stressjumpint}
+\end{equation}
+Since the derivation above is also valid for any subset of $\Omega_\epsilon$
+containing a part of $\Gamma$, \eqref{eq:stressjumpint} must hold for any part
+of $\Gamma$.  Therefore
+\begin{equation}
+  0 = \jmp{\vct T}\cdot\vct n + \sigma\kappa\vct n.
+\end{equation}
+With $\vct T = -p\vct I + 2\mu\vct D$ we finally get the interface condition
+for the stresses,
+\begin{equation}
+  \label{eq:stress_jump}
+  \jmp{p}\vct n - \jmp{2\mu\tenD}\cdot\vct n = \sigma\kappa\vct n.
+\end{equation}
+The surface tension force is seen to introduce a discontinuity in the normal
+stresses across the interface.  The tangential stresses are continuous.
+
+\section{Interface conditions for the pressure and the viscous term}
+The previous section gave a brief derivation of the interface conditions for
+immiscible and incompressible two-phase flow without mass transfer.  In order
+to use these conditions for the discretization of the Navier-Stokes equations
+\eqref{eq:ns1} and \eqref{eq:ns2}, we need to rewrite them into a more suitable
+form.  In particular, we want to find explicit expressions for the jump in the
+pressure $\jmp p$ and the viscous term $\jmp{\mu\grad\vct u}$.  The following
+derivation is based on \cite{Hansen05} and \cite{Kang00}.
+
+First, a jump condition for the pressure is obtained by taking the inner
+product of \eqref{eq:stress_jump} with the normal vector $\vct n$,
+\begin{equation}
+  \jmp p = \vct n\cdot\jmp{2\mu\tenD}\cdot\vct n + \sigma\kappa
+      = 2\jmp{\mu}\vct n\cdot \grad\vct u \cdot\vct n
+        + \sigma\kappa,
+  \label{eq:jump_pressure}
+\end{equation}
+where \eqref{eq:jmpngradun} was used for the second equality.
+
+To find the jump in the viscous term, it is first decomposed into an interface
+normal coordinate system as
+\begin{equation}
+  \begin{split}
+    \jmp{\mu\grad\vct u} &=
+  \left(\vct n\cdot\jmp{\mu\grad\vct u}\cdot\vct n\right)\vct n\otimes\vct n +
+  \left(\vct t\cdot\jmp{\mu\grad\vct u}\cdot\vct t\right)\vct t\otimes\vct t
+        \\ &\quad+
+  \left(\vct n\cdot\jmp{\mu\grad\vct u}\cdot\vct t\right)\vct n\otimes\vct t +
+  \left(\vct t\cdot\jmp{\mu\grad\vct u}\cdot\vct n\right)\vct t\otimes\vct n,
+  \end{split}
+\end{equation}
+where $\otimes$ denotes the dyadic product.  We already showed that
+$\jmp{\grad\vct u}\cdot\vct t = 0$ and $\vct n\cdot\jmp{\grad\vct u}\cdot\vct
+n = 0$, cf.\ \eqref{eq:jmpJut} and \eqref{eq:jmpngradun}, which gives
+\begin{align}
+  \vct n\cdot\jmp{\mu\grad\vct u}\cdot\vct n &=
+    \jmp{\mu}\,\vct n\cdot\grad\vct u\cdot\vct n, \\
+  \vct t\cdot\jmp{\mu\grad\vct u}\cdot\vct t &=
+    \jmp{\mu}\,\vct t\cdot\grad\vct u\cdot\vct t, \\
+  \vct n\cdot\jmp{\mu\grad\vct u}\cdot\vct t &=
+    \jmp{\mu}\,\vct n\cdot\grad\vct u\cdot\vct t.
+\end{align}
+We then take the inner product of \eqref{eq:stress_jump} with $\vct t$, which
+gives
+\begin{equation}
+  \vct t\cdot\jmp{\mu\left(\grad\vct u + (\grad\vct u)^T \right)}\cdot\vct n
+  = \vct t\cdot\jmp{\mu\grad\vct u} \cdot\vct n
+    + \jmp{\mu}\vct n\cdot\grad\vct u \cdot\vct t
+  = 0,
+\end{equation}
+or
+\begin{equation}
+  \vct t\cdot\jmp{\mu\grad\vct u}\cdot\vct n =
+    - \jmp{\mu}\vct n\cdot\grad\vct u \cdot\vct t.
+\end{equation}
+The jump in the viscous term becomes
+\begin{multline}
+  \jmp{\mu\grad\vct u} = \jmp{\mu} \Big(
+       (\vct n\cdot\grad\vct u\cdot\vct n)\vct n\otimes\vct n
+     + (\vct n\cdot\grad\vct u\cdot\vct t)\vct n\otimes\vct t \\
+     - (\vct n\cdot\grad\vct u\cdot\vct t)\vct t\otimes\vct n
+     + (\vct t\cdot\grad\vct u\cdot\vct t)\vct t\otimes\vct t \Big).
+\end{multline}
+This can be simplified further by noting that
+\begin{equation}
+  (\grad\vct u\cdot t)\otimes\vct t
+  = (\vct n\cdot\grad\vct u\cdot\vct t)\vct n\otimes\vct t
+    + (\vct t\cdot\grad\vct u\cdot\vct t)\vct t\otimes\vct t.
+\end{equation}
+Thus we obtain the expression for the jump in the viscous term that has been
+used in the present work,
+\begin{multline}
+  \jmp{\mu\grad\vct u} = \jmp{\mu} \Big(
+       (\vct n\cdot\grad\vct u\cdot\vct n)\vct n\otimes\vct n
+     - (\vct n\cdot\grad\vct u\cdot\vct t)\vct t\otimes\vct n \\
+     + (\grad\vct u\cdot\vct t)\otimes\vct t \Big).
+  \label{eq:jumptens}
+\end{multline}
+
+\section{Summary}
+This chapter has given a brief derivation of the immiscible and incompressible
+Navier-Stokes equations for two-phase flow \eqref{eq:ns1} and \eqref{eq:ns2},
+where the viscosity is assumed constant in each phase.  The effect of surface
+tension is included as a singular source term.
+
+Fluid-fluid interface conditions have been discussed, and it has been shown how
+the singular source term and a jump in viscosity lead to a set of interface
+jump conditions for the pressure \eqref{eq:jump_pressure} and the viscous term
+\eqref{eq:jumptens}.

+\chapter{Numerical methods}
+\label{chap:numerical-methods}
+This chapter describes the numerical methods that have been used in this thesis
+to solve the Navier-Stokes equations for two-phase flow.  First, a brief
+introduction to the level-set method is given, which is followed by an outline
+of the two projection methods that have been used to solve the Navier-Stokes
+equations.  The spatial and temporal discretization methods are then
+summarized, and at the end of the chapter the new methods to calculate the
+curvature and the normal vectors are presented.
+
+\section{The level-set method}
+\label{sec:level-set}
+In order to solve the Navier-Stokes equations for two-phase flow, we need to
+know the location of the interface.  The level-set method proposed by
+\citet{Osher88} allows us to capture the interface location as the zero level
+set of the level-set function $\varphi(\vct x,t)$.  The level-set function is
+typically defined as a signed-distance function,
+\begin{equation}
+  \varphi(\vct x,t) = \begin{cases}
+     d(\vct x,t) & \text{if } \vct x\in\Omega_2, \\
+    -d(\vct x,t) & \text{if } \vct x\in\Omega_1, \\
+  \end{cases}
+\end{equation}
+where $d(\vct x,t)$ is the shortest distance to the interface $\Gamma$,
+\begin{equation}
+  d(\vct x,t) = \min_{\vct x_I \in \Gamma} |\vct x - \vct x_I|.
+\end{equation}
+Thus the interface can be defined implicitly as
+\begin{equation}
+  \Gamma(t) = \set{\vct x\in\Omega}{\varphi(\vct x,t)=0},
+              \quad t\in \mathbb R^+.
+\end{equation}
+
+The position of the interface is updated by solving an advection equation for
+$\varphi$,
+\begin{equation}
+  \label{eq:ls_adeq}
+  \pdt{\varphi} + \vct{\hat u}\cdot\grad\varphi = 0,
+\end{equation}
+where $\vct{\hat u}$ is the velocity at the interface extended to the entire
+domain.  We extend the interface velocity through solving
+a velocity-extrapolation equation,
+\begin{equation}
+  \label{eq:ls_velextr}
+  \pd{\vct{\hat u}}{\tau} + S(\varphi)\vct n\cdot\grad\vct{\hat u} = 0,
+  \quad \vct{\hat u}_{\tau=0} = \vct u,
+\end{equation}
+to steady state, cf.\ \cite{Adalsteinsson99,Zhao96}.  Here $\tau$ is
+a pseudo-time and $S$ is a smeared sign function which is equal to zero at the
+interface,
+\begin{equation}
+  S(\varphi) = \frac{\varphi}{\sqrt{\varphi^2+2\Delta x^2}}.
+\end{equation}
+
+When we solve the level-set equation \eqref{eq:ls_adeq}, the non-uniform
+advection will distort the signed-distance property of the level-set function,
+and numerical dissipation error adds to this distortion.  The level-set
+function is therefore reinitialized regularly by solving
+\begin{equation}
+  \label{eq:ls_reinit}
+  \begin{split}
+    \pd{\varphi}{\tau} + S(\varphi_0)(|\grad\varphi|-1) &= 0, \\
+    \varphi(\vct x,0) &= \varphi_0(\vct x),
+  \end{split}
+\end{equation}
+to steady state as proposed by \citet{Sussman94}.  The level-set function just
+before initialization is used as the initial condition $\varphi_0$.
+
+The level-set equations \eqref{eq:ls_adeq}, \eqref{eq:ls_velextr}, and
+\eqref{eq:ls_reinit} are discretized in time and space as described in the
+following sections.  The method presented by \citet{Adalsteinsson95} is used to
+improve the computational speed.  The method is often called the narrow-band
+method, since the level-set function is only updated in a narrow band across
+the interface at each time step.
+
+One of the advantages of the level-set method is that normal vectors and
+curvatures can be readily calculated from the level-set function, that is,
+\begin{align}
+  \label{eq:norm}
+  \vct n &= \frac{\grad\varphi}{|\grad\varphi|}, \\
+  \label{eq:curv}
+  \kappa &= \div\left(\frac{\grad\varphi}{|\grad\varphi|}\right).
+\end{align}
+
+\section{Projection methods}
+\label{sec:projection-method}
+We have employed two different projection methods in this thesis to solve the
+incompressible Navier-Stokes equations for two-phase flow \eqref{eq:ns1} and
+\eqref{eq:ns2}.  Papers A, B, and C used the direct projection
+scheme~1~(DP1)~\cite{Hansen05}, and Paper D used the more standard Chorin
+projection method \cite{Chorin68}.
+
+The projection methods are a family of methods for the solution of the
+incompressible Navier-Stokes equations that are based on the Helmholtz-Hodge
+theorem.  This theorem states that an arbitrary vector field can be decomposed
+into a divergence-free part and a rotation-free part.  That is, any vector
+field $\vct a$ can be written as
+\begin{equation}
+  \vct a = \vct a' + \grad\psi,
+\end{equation}
+where $\vct a'$ is a vector with $\div\vct a' = 0$ and $\psi$ is a scalar
+potential.  The proof of this theorem can be found in for instance
+\cite[§3.44]{Aris89} or \cite{Chorin00}.
+
+\subsection{The direct projection scheme 1}
+The DP1 was developed by \citet{Hansen05} and is based on a direct application
+of the Helmholtz-Hodge theorem.  We assume that the velocity $\vct u$ is
+sufficiently smooth, and then rewrite \eqref{eq:navier-stokes-2} to get
+\begin{equation}
+  \label{eq:divFreeVel}
+  \pdt{\vct u} = \vct w - \frac{\grad p}{\rho},
+\end{equation}
+where
+\begin{equation}
+  \vct w = - (\vct u\cdot\grad)\vct u + \nu\grad^2\vct u + \vct f.
+  \label{eq:continuousRightHandVector}
+\end{equation}
+The divergence of \eqref{eq:divFreeVel} yields a Poisson equation for the
+pressure,
+\begin{equation}
+  \div\left(\frac{\grad p}{\rho}\right) = \div\vct w.
+  \label{eq:PoissonDP1}
+\end{equation}
+The DP1 scheme follows from a direct numerical discretization of the above
+equations.  First, $\vct w$ is calculated with
+\eqref{eq:continuousRightHandVector}.  Then the pressure is found by solving
+the Poisson equation \eqref{eq:PoissonDP1}.  Finally, an Euler step is used to
+solve \eqref{eq:divFreeVel}, that is,
+\begin{equation}
+  \vct u^{n+1} = \vct u^n + \Delta t\left(\vct w - \frac{\grad p}{\rho}\right).
+  \label{eq:dp1-update}
+\end{equation}
+
+\subsection{The Chorin projection method}
+The Chorin projection method was presented by \citet{Chorin68}, and is today
+one of the standard methods for solving the Navier-Stokes equations, e.g.\
+\cite{Walker12}.  The method is briefly presented in the following.
+
+Let $\Delta t$ be the time step, and consider the discretization of the
+momentum equation \eqref{eq:navier-stokes-2} with the forward Euler method,
+\begin{equation}
+  \frac{\vct u^{n+1} - \vct u^n}{\Delta t}
+  = -\vct u^n\cdot\grad\vct u^n
+    - \frac{\grad p^{n+1}}{\rho} + \frac\mu\rho\lapl\vct u^n + \vct f,
+  \label{eq:discmomeq}
+\end{equation}
+where $\vct u^n\equiv\vct u(\vct x,n\Delta t)$ and $p^n\equiv p(\vct x,n\Delta
+t)$ are assumed known at time level $n$.  Note that the pressure gradient is
+evaluated at time level $n+1$.  Next, to solve \eqref{eq:discmomeq} in two
+steps, we introduce the intermediate velocity field $\vct u^\star$,
+\begin{equation}
+  \frac{\vct u^{n+1} - \vct u^\star + \vct u^\star - \vct u^n}{\Delta t}
+  = -\vct u^n\cdot\grad\vct u^n
+    - \frac{\grad p^{n+1}}{\rho} + \frac\mu\rho\lapl\vct u^n + \vct f,
+\end{equation}
+which is chosen such that
+\begin{align}
+  \label{eq:ustar}
+  \frac{\vct u^\star - \vct u^n}{\Delta t}
+    &= -\vct u^n\cdot\grad\vct u^n + \frac\mu\rho\lapl\vct u^n + \vct f, \\
+  \label{eq:unext}
+  \frac{\vct u^{n+1} - \vct u^\star}{\Delta t} &= - \frac{\grad p^{n+1}}{\rho}.
+\end{align}
+From \eqref{eq:ustar} we get an explicit expression for $\vct u^\star$,
+\begin{equation}
+  \vct u^{\star} = \vct u^n
+    + \Delta t\left(-\vct u^n\cdot\grad\vct u^n
+        + \frac\mu\rho\,\lapl\vct u^n + \vct f\right).
+\end{equation}
+Next, the divergence of \eqref{eq:unext} and $\div\vct u^{n+1} = 0$ yields
+a Poisson equation for the pressure,
+\begin{equation}
+  \div\left(\frac{\grad p^{n+1}}{\rho}\right)
+    = \frac{\div\vct u^\star}{\Delta t}.
+  \label{eq:PoissonChorin}
+\end{equation}
+Finally, we obtain for \eqref{eq:unext}
+\begin{equation}
+  \vct u^{n+1} = \vct u^\star - \Delta t\frac{\grad p^{n+1}}{\rho}.
+  \label{eq:velcorrection}
+\end{equation}

+\section{Spatial discretization}
+\label{sec:x-discr}
+The governing equations \eqref{eq:ns1}, \eqref{eq:ns2}, \eqref{eq:ls_adeq},
+\eqref{eq:ls_velextr}, and \eqref{eq:ls_reinit} are discretized on a staggered
+grid~\cite{Harlow65}, where the scalar values are located at the cell centres
+and the vector values are located at the cell edges, see
+\cref{fig:staggered-grid}.  The domain boundary coincides with cell edges, and
+the fixed grid spacing is $\Delta x$ in the $x$ direction and $\Delta y$ in the
+$y$ direction.

+The $x$- and $y$-derivatives, divergence, and Laplacian operators are

+    &= \frac{p_{i+1,j} - p_{i,j}}{\Delta x}, \\

+\end{align}
+respectively.  Here $\vct u = (u,v)$ is a vector and $p$ is a scalar.  Note
+that the gradient of a scalar is a vector and has values located at the cell
+edges.  These definitions are consistent with the staggered grid, since the
+gradient returns a vector with components defined on the cell faces, while the
+divergence and the Laplacian returns a scalar defined at the cell centres.
+
+\subsection{Advective terms}
+The advective terms, $\vct u\cdot\grad\vct u$ in the momentum equation
+\eqref{eq:ns2} and $\vct{\hat u}\cdot\grad\varphi$ in the level-set equation
+\eqref{eq:ls_adeq}, and the normal derivative $\vct n\cdot\grad\vct{\hat u}$ in
+the velocity-extrapolation equation \eqref{eq:ls_velextr} are discretized with
+the weighted essentially non-oscillatory (WENO) scheme, cf.~\cite{Fedkiw99}
+and~\cite{Jiang96}.  The WENO scheme is a high-order upwind scheme that is
+fifth-order accurate in smooth regions.  In nonsmooth regions the accuracy is
+reduced to a minimum of third order.  The following is a brief outline of the
+WENO scheme.
+
+First, when we calculate the advective term for the velocity, the vector
+components are required on all cell edges.  That is, we must interpolate the
+$x$-component of the velocity to the location of the $y$-component of the
+velocity and vice versa.  To do this we use a linear interpolation,
+\begin{align}
+  u_{i,j+\frac 1 2} &= \frac 1 4\left(
+      u_{i-\frac 1 2,j  } + u_{i-\frac 1 2,j+1}
+    + u_{i+\frac 1 2,j+1} + u_{i+\frac 1 2,j  } \right), \\
+  v_{i+\frac 1 2,j} &= \frac 1 4\left(
+      v_{i,  j-\frac 1 2} + v_{i+1,j-\frac 1 2}
+    + v_{i+1,j+\frac 1 2} + v_{i  ,j+\frac 1 2} \right).
+\end{align}
+
+Similarly, when we calculate the advective term for the level-set function
+$\varphi$, we first interpolate the velocity to the scalar grid,
+\begin{align}
+  u_{i,j} &= \frac 1 2\left( u_{i+\frac 1 2,j} + u_{i-\frac 1 2,j} \right), \\
+  v_{i,j} &= \frac 1 2\left( v_{i,j+\frac 1 2} + v_{i,j-\frac 1 2} \right).
+\end{align}
+
+We now consider the WENO scheme for the advective operator in 1D at the point
+$x_{i+\frac 1 2}$.  The scheme extends naturally to higher dimensions.  First,
+if $u_{i+\frac 1 2} = 0$, then
+\begin{equation}
+  \left. u\pd u x \right|_{i+\frac 1 2} = 0.
+\end{equation}
+Otherwise we need to calculate a set of five differences that depend on the
+upwind direction.  The differences are denoted $\Delta v_k$ for $k=1,\dots,5$.
+If $u_{i+\frac 1 2}>0$, then we calculate
+\begin{equation}
+  \Delta v_k = \frac{u_{i+\frac{2k-5} 2} - u_{i+\frac{2k-7} 2}}{\Delta x}.
+\end{equation}
+Otherwise if $u_{i+\frac 1 2}<0$, we calculate
+\begin{equation}
+  \Delta v_k = \frac{u_{i-\frac{2k-9} 2} - u_{i-\frac{2k-7} 2}}{\Delta x}.
+\end{equation}
+Next we calculate expressions for the smoothness of three substencils,
+\begin{align}
+  S_1 &= \frac{13}{12}(\Delta v_1 - 2\Delta v_2 + \Delta v_3)^2
+    + \frac 1 4 (\Delta v_1 - 4\Delta v_2 + 3\Delta v_3)^2, \\
+  S_2 &= \frac{13}{12}(\Delta v_2 - 2\Delta v_3 + \Delta v_4)^2
+    + \frac 1 4 (\Delta v_2 - \Delta v_4)^2, \\
+  S_3 &= \frac{13}{12}(\Delta v_3 - 2\Delta v_4 + \Delta v_5)^2
+    + \frac 1 4 (3\Delta v_3 - 4\Delta v_4 + \Delta v_5)^2,
+\end{align}
+where a small $S$ indicates a smooth substencil.  These smoothness factors are
+then used to compute weights for the substencils,
+\begin{equation}
+  w_k = \frac{b_k}{b_1+b_2+b_3},
+\end{equation}
+for $k = 1,2,3$, where
+\begin{equation}
+  b_1 = \frac 1 {10}\frac 1 {(\epsilon+S_1)^2},\quad
+  b_2 = \frac 6 {10}\frac 1 {(\epsilon+S_2)^2},\quad
+  b_3 = \frac 3 {10}\frac 1 {(\epsilon+S_3)^2}.
+\end{equation}
+Here $\epsilon$ is a regularization parameter that is used to avoid division by
+zero.  We have used $\epsilon = 10^{-6}$ in this work.  Finally, the WENO
+scheme for the gradient becomes
+\begin{multline}
+  \left. \pd u x \right|_{i+\frac 1 2} \simeq
+      w_1\left(\frac 1 3\Delta v_1 - \frac 7 6\Delta v_2
+        + \frac{11} 6 \Delta v_3\right) \\
+    + w_2\left(-\frac 1 6\Delta v_2 + \frac 5 6\Delta v_3
+        + \frac 1 3 \Delta v_4\right) \\
+    + w_3\left(\frac1 3\Delta v_3 + \frac 5 6\Delta v_4
+        - \frac 1 6 \Delta v_5\right).
+\end{multline}
+
+\subsection{The viscous term}
+The viscous term $\mu\lapl\vct u$ in the Navier-Stokes equations is discretized
+by standard second-order central differences using the ghost-fluid method
+(GFM)~\cite{Fedkiw99,Kang00,Liu00}.  This method includes the jump in the
+viscous term at the interface \eqref{eq:jumptens} in the discretization stencil
+in a sharp manner.
+
+In the following we present the GFM scheme in the one-dimensional case.  The
+extension to higher dimensions is straightforward.  In order to simplify the
+notation, we omit the half indices and let $k\equiv i+\frac 1 2$.  Further, we
+consider a general case where
+\begin{equation}
+  \jmp u = a_\Gamma, \qquad \jmp{\mu\pd u x} = b_\Gamma.
+\end{equation}
+For the viscous term, $a_\Gamma = 0$, cf.\ \eqref{eq:jmpu}, and $b_\Gamma$ is
+given by the jump tensor~\eqref{eq:jumptens}.  The jump tensor is calculated at
+the cell centres near the interface with the second-order central-difference
+scheme.  It is then interpolated linearly to the cell edges, from where it is
+again interpolated linearly to the interface when needed.
+
+If the interface does not cross the stencil, then the GFM scheme reduces to the
+standard second-order central-difference stencil.  Else there are four
+stencils, depending on the location of the interface.  One such interface
+configuration is sketched in \cref{fig:gfm-scheme-example}.  In all the
+stencils, $\theta$ is defined as the relative distance from the interface to
+the node on the left, for instance
+\begin{equation}
+  \theta = \frac{|\varphi_{k}|}{|\varphi_{k}| + |\varphi_{k+1}|},
+\end{equation}
+where $\varphi_k$ and $\varphi_{k+1}$ are the level-set function values
+linearly interpolated to the vector grid.  The four stencils are given below,
+where $h\equiv\Delta x$.
+\begin{enumerate}
+  \item Phase 1 is to the left and interface lies between $k$ and $k+1$:
+    \begin{align}
+      \begin{split}
+        \left.\pd{} x\left(\mu\pd u x\right)\right|_{x_k}
+          &= \frac{\hat\mu\left(u_{k+1} - u_{k}\right)
+                 - \mu_1\left(u_{k} - u_{k-1}\right)}{h^2} \\
+          &\qquad
+             - \frac{\hat\mu a_\Gamma}{h^2}
+             - \frac{\hat\mu b_\Gamma (1-\theta)}{\mu_2 h},
+      \end{split} \\
+       \hat\mu &= \frac{\mu_1\mu_2}{\theta\mu_2 + (1-\theta)\mu_1}.
+    \end{align}
+  \item Phase 1 is to the left and interface lies between $k-1$ and $k$:

+          &= \frac{\mu_2\left(u_{k+1} - u_{k}\right)
+                - \hat\mu\left(u_{k} - u_{k-1}\right)}{h^2} \\
+          &\qquad
+            + \frac{\hat\mu a_\Gamma}{h^2}
+            - \frac{\hat\mu b_\Gamma \theta}{\mu_1 h},
+      \end{split} \\
+      \hat\mu &= \frac{\mu_1\mu_2}{\theta\mu_2 + (1-\theta)\mu_1}.
+    \end{align}
+  \item Phase 2 is to the left and interface lies between $k$ and $k+1$:
+    \begin{align}
+      \begin{split}
+        \left.\pd{} x\left(\mu\pd u x\right)\right|_{x_k}
+          &= \frac{\hat\mu\left(u_{k+1} - u_{k}\right)
+                - \mu_2\left(u_{k} - u_{k-1}\right)}{h^2} \\
+          &\qquad
+            + \frac{\hat\mu a_\Gamma}{h^2}
+            + \frac{\hat\mu b_\Gamma (1-\theta)}{\mu_1 h},
+      \end{split} \\
+      \hat\mu &= \frac{\mu_1\mu_2}{\theta\mu_1 + (1-\theta)\mu_2}.
+    \end{align}
+  \item Phase 2 is to the left and interface lies between $k-1$ and $k$:
+    \begin{align}
+      \begin{split}
+        \left.\pd{} x\left(\mu\pd u x\right)\right|_{x_k}
+          &= \frac{\mu_1\left(u_{k+1} - u_{k}\right)
+                - \hat\mu\left(u_{k} - u_{k-1}\right)}{h^2} \\

+      \end{split} \\
+      \hat\mu &= \frac{\mu_1\mu_2}{\theta\mu_1 + (1-\theta)\mu_2}.

+\subsection{Pressure Poisson equation}
+\label{sec:pressure-poisson}
+The Laplace operator in the Poisson equations \eqref{eq:PoissonDP1} and
+\eqref{eq:PoissonChorin} is also discretized by standard second-order central
+differences using the GFM~\cite{Kang00,Liu00}.  The GFM was discussed in the
+previous section, where stencils were given for the viscous term in the
+one-dimensional case.  For the pressure, the stencils are the same except we
+use $p$ instead of $u$, and $1/\rho$ and $1/\hat\rho$ instead of $\mu$ and
+$\hat\mu$.  To find the jump in the pressure at the interface, $\jmp
+p = a_\Gamma$, the jump condition \eqref{eq:jump_pressure} is calculated at the
+cell centres and then interpolated to the interface.  In addition, we use that
+$b_\Gamma = 0$, which is justified by \citet[Section~3.7]{Kang00}.
+
+The resulting linear system for the pressure is solved with a solver from the
+Portable, Extensible Toolkit for Scientific Computation (PETSc)~\cite{PETSc}.
+PETSc makes available a large selection of solvers.  In most cases, we used the
+direct solver based on LU factorisation or the conjugate gradient method with
+incomplete Cholesky factorisation.  In some cases, we used the GMRES solver
+with a preconditioner, either incomplete LU factorisation or an algebraic
+multigrid method.  See \cite{PETSc} for more details and a list of available
+methods, and see for example~\cite{Iserles09} or~\cite{Saad03} for an
+introduction to linear solvers.
+
+Finally, the gradient of the pressure, used in \eqref{eq:divFreeVel} and
+\eqref{eq:velcorrection}, is also calculated with the GFM.  In one dimension,
+the stencil is
+\begin{align}
+  \left. \frac 1 \rho \pd p x\right|_{i+\frac 1 2}
+           &= \frac 1 {\hat\rho} \frac{(p_{i+1} - a_\Gamma) - p_i} h, \\
+  \hat\rho &= \theta\rho_1 + (1-\theta)\rho_2,
+\end{align}
+if $\phi_i\leq 0$ and $\phi_{i+1}>0$, or else
+\begin{align}
+  \left. \frac 1 \rho \pd p x\right|_{i+\frac 1 2}
+           &= \frac 1 {\hat\rho} \frac{(p_{i+1} + a_\Gamma) - p_i} h, \\
+  \hat\rho &= \theta\rho_2 + (1-\theta)\rho_1,
+\end{align}
+where
+\begin{equation}
+  \theta = \frac{|\varphi_{i}|}{|\varphi_{i}| + |\varphi_{i+1}|}.
+\end{equation}
+
+\section{Temporal discretization}
+\label{sec:t-discr}
+The temporal discretization is done with the explicit strong
+stability-preserving Runge-Kutta (SSP-RK) schemes, see
+\cite{Ketcheson05,Shu88}.  The idea behind the SSP-RK schemes is to preserve
+the stability of a low-order method when it is extended to higher order.  It is
+argued in \cite{Gottlieb01} that if one extends the forward Euler method, which
+is total variation diminishing (TVD) for a suitable discretization of a scalar
+conservation law, to a non-SSP higher-order method, then overshoots may occur
+at discontinuities.
+
+An SSP-RK method can be written as a convex sum of explicit Euler steps with
+time step $\Delta t$,
+\begin{equation}
+  \mathcal E\left(x^n\right) = x^n + \Delta t \mathcal F(x^n,t^n).
+\end{equation}
+where $\mathcal F$ is the residual of the PDE to be solved.  In this thesis we
+have used two methods:  The third-order three-stage SSP-RK method~\cite{Shu88},
+\begin{equation}
+  \begin{split}
+    x^{(1)} &= \mathcal E\left(x^n\right), \\
+    x^{(2)} &= \frac 3 4 x^n + \frac 1 4\mathcal E\left(x^{(1)}\right), \\
+    x^{n+1} &= \frac 1 3 x^n + \frac 2 3\mathcal E\left(x^{(2)}\right),
+  \end{split}
+  \label{eq:ssprk33}
+\end{equation}
+and the third-order four-stage SSP-RK method~\cite{Kraaijevanger91},
+\begin{equation}
+  \begin{split}
+    x^{(1)} &= \frac 1 2 x^n + \frac 1 2\mathcal E\left(x^n\right), \\
+    x^{(2)} &= \frac 1 2 x^{(1)} + \frac 1 2\mathcal E\left(x^{(1)}\right), \\
+    x^{(3)} &= \frac 2 3 x^n + \frac 1 6 x^{(2)}
+               + \frac 1 6\mathcal E\left(x^{(2)}\right), \\
+    x^{n+1} &= \frac 1 2 x^{(3)} + \frac 1 2\mathcal E\left(x^{(3)}\right).
+  \end{split}
+  \label{eq:ssprk34}
+\end{equation}
+
+The semi-discretized velocity-extrapolation equation \eqref{eq:ls_velextr} and
+level-set reinitialization equation \eqref{eq:ls_reinit} can be written as
+systems of ordinary differential equations (ODEs) of the form
+\begin{equation}
+  \od{\vct \psi} \tau = \vct F(\vct\psi,\tau),
+\end{equation}
+where $\vct\psi$ is a vector containing the discrete variables and $\vct F$
+contains the spatially discretized terms.  The explicit Euler step becomes
+\begin{equation}
+  \mathcal E(\vct\psi^n) = \vct\psi^n + \Delta\tau \vct F(\vct\psi^n,\tau^n).
+\end{equation}
+In this thesis, these equations are solved with the third-order four-stage
+SSP-RK method \eqref{eq:ssprk34}.  The four-stage method is used because it is
+more accurate than the three-stage method.  We wanted to make sure that the
+error is mainly dominated by the spatial discretization.
+
+The semi-discretized Navier-Stokes equations \eqref{eq:navier-stokes-1} and
+\eqref{eq:navier-stokes-2} are solved together with the level-set advection
+equation \eqref{eq:ls_adeq} with the third-order three-stage SSP-RK method
+\eqref{eq:ssprk33}.  Here an explicit Euler step $\mathcal E(\vct
+u^n,\varphi^n)$ consists of the following steps:
+\begin{enumerate}
+  \item Calculate the curvature and the normal vectors from $\varphi^n$ with
+    one of the methods described in \cref{sec:curvature}.
+  \item Calculate the intermediate velocity field, either $\vct w$
+    \eqref{eq:continuousRightHandVector} or $\vct u^\star$ \eqref{eq:ustar}.
+  \item Solve the Poisson equation \eqref{eq:PoissonDP1} or
+    \eqref{eq:PoissonChorin} for the pressure as described in
+    \cref{sec:pressure-poisson}.
+  \item Correct the velocity field with either \eqref{eq:dp1-update} or
+    \eqref{eq:velcorrection}.
+  \item Advect the level-set function $\varphi^n$ with \eqref{eq:ls_adeq}.
+\end{enumerate}
+
+\section{Time step restriction}
+\label{sec:deltaT}
+We employ the Courant-Friedrich-Lewy~(CFL) condition to allow adaptive time
+stepping and to enforce stability.  The CFL condition that is used in this
+thesis is
+\begin{equation}
+  \Delta t = \frac{C}{\frac{C_c + C_v} 2
+             + \sqrt{(C_c + C_v)^2 + 4C_g^2 + 4C_s^2}},
+\end{equation}
+where the CFL restriction $C<1$, and $C_c$, $C_v$, $C_s$, and $C_g$ represent
+the contributions from the convective term, the viscous stresses, the surface
+tension, and the gravity, respectively,
+\begin{align}
+  C_c &=  \frac{\max_{i,j}|u_{i,j}|}{\Delta x}
+        + \frac{\max_{i,j}|v_{i,j}|}{\Delta y}, \\
+  C_v &= 2\max\left(\frac{\mu_1}{\rho_1},\frac{\mu_2}{\rho_2}\right)
+         \left(\frac{1}{\Delta x^2} + \frac{1}{\Delta y^2}\right), \\
+  C_s &= \sqrt{\frac{\sigma\max_{i,j}|\kappa_{i,j}|}
+                    {\max(\rho_1,\rho_2)\min(\Delta x^2,\Delta y^2)}}, \\
+  C_g &= \sqrt{\frac{|g_x|}{\Delta x} + \frac{|g_y|}{\Delta y}}.
+\end{align}
+This CFL condition is discussed in more detail by~\citet{Lervag08}, and it is
+based on the condition by \citet{Kang00}.

+\section{Axisymmetry}
+For axisymmetric flow, the governing equations \eqref{eq:ns1} and
+\eqref{eq:ns2} become
+\begin{equation}
+  \frac 1 r \pd{} r\left(r u\right) + \pd v z = 0,
+\end{equation}
+\begin{multline}
+  \rho\left(\pdt u + u\pd u r + v\pd u z\right) = -\pd p r \\
+    + \mu\left(\frac 1 r \pd{} r\left(r \pd u r\right)
+          + \pdd u z - \frac u {r^2}\right) + \rho f_r + {f_s}_r,
+\end{multline}
+and
+\begin{multline}
+  \rho\left(\pdt v + u\pd v r + v\pd v z\right) = -\pd p z \\
+    + \mu\left(\frac 1 r \pd{} r\left(r \pd v r\right)
+      + \pdd v z\right) + \rho f_z + {f_s}_z.
+\end{multline}
+Here $u$ and $v$ are the radial and axial velocity components, $f_r$ and $f_z$
+are the radial and axial body-force components, and ${f_s}_r$ and ${f_s}_z$ are
+the radial and axial components of the singular surface force, respectively.
+The equations are solved as explained in the previous sections.
+
+\section{Discretization of the curvature and the normal vector}
+\label{sec:curvature}
+As stated in \cref{sec:level-set}, the normal vector \eqref{eq:norm} and the
+curvature \eqref{eq:curv} can be calculated from the level-set function as
+\begin{align*}
+  \vct n &= \frac{\grad\varphi}{|\grad\varphi|}, \\
+  \kappa &= \div\left(\frac{\grad\varphi}{|\grad\varphi|}\right).
+\end{align*}
+They are typically discretized with the standard second-order
+central-difference scheme, cf.\ \cite{Kang00,Sethian03,Xu06}.  The normal
+vector is calculated at the cell edges, and the curvature is calculated at the
+grid nodes.  The curvature is then interpolated to the interface where needed
+with linear interpolation, for instance with
+\begin{equation}
+  \kappa_\Gamma = \frac{|\varphi_{i,j}|\kappa_{i+1,j}
+  + |\varphi_{i+1,k}|\kappa_{i,j}}{|\varphi_{i,j}| + |\varphi_{i+1,j}|}.
+  \label{eq:curvature-gamma}
+\end{equation}
+
+If the level-set method is used to capture non-trivial geometries, then it will
+contain kink regions, that is, areas where the gradient of the level-set
+function is discontinuous.  \Cref{fig:level-set-function} shows a simple
+example of such a kink region for a level-set function in a one-dimensional
+domain that captures two interfaces, one on each side of $x_i$.  The kink at
+$x_i$ may lead to large errors both for the curvature and the normal vector if
+one is not careful.  Errors in the curvature lead to errors in the surface
+tension force and in the pressure, which in turn lead to errors in the
+interface evolution and in the two-phase flow.  Errors in the normal vector
+affect both the calculation of the viscous jump condition and the advection of
+the interface.  If the level-set method is used to study for example
+coalescence and breakup of drops, these errors may severely affect the
+simulations.

+\end{figure}
+
+This problem was to our knowledge first described by \citet{Smereka03}, who
+increase the numerical smoothing in the curvature discretization to lessen the
+effect.  Several non-smearing approaches have subsequently been developed.
+\citet{Macklin05} used the level-set method to study tumor growth, and they
+present a one-sided direction-difference scheme for the discretization of the
+normal vector and the curvature.  Later, \citet{Macklin06} presented an
+improved geometry-aware curvature discretization, where the curvature is
+calculated based on a local least-squares parametrisation of the interface.
+
+A different approach to avoid the kinks was presented by \citet{Salac08}.  They
+used a level-set extraction technique, where an extraction algorithm was used
+to reconstruct separate level-set functions for each distinct \emph{body}.  The
+term \emph{body} is used here to denote a subset of a given phase or fluid.
+For example, in the case of two drops of water colliding in air, the water
+drops would make two distinct bodies.  One can also avoid the extraction
+algorithm altogether by use of multiple marker functions for different bodies,
+see for instance \cite{Coyajee09,Kwakkel12}.  Note, however, that the latter
+approach means that the different bodies will not coalesce unless explicit
+action is made, cf.~\cite{Kwakkel13}.  Also, both of the approaches mentioned
+here fails to handle the problem of kinks from a single body.  That is, there
+may still be kink areas due to deformed bodies, for instance bodies with thin
+filaments or tails, or bodies shaped like horse shoes.
+
+In the following, we first present the direction-difference
+scheme~\cite{Macklin05}.  We then describe the curve-fitting discretization
+method and the local level-set extraction method.
+
+\subsection{Direction-difference scheme}
+\label{sec:dds}
+The direction-difference scheme (DDS) was introduced by \citet{Macklin05}.  It
+uses a quality function to ensure that the difference stencils never cross any
+kink regions.  The DDS is used in Papers A--C to calculate the normal vectors.
+However, in Paper C it is shown that the DDS does not always yield an accurate
+approximation of the normal vector.
+
+The basic strategy is to use a combination of central differences and one-sided
+differences based on the values of a quality function,
+\begin{equation}
+  Q(\vct x) = \left| 1 - |\grad\varphi(\vct x)|\right|.
+  \label{eq:quality}
+\end{equation}
+The quality function is approximated with central differences, and is used to
+detect the areas where the level-set function differs from the signed-distance
+function.  In the following, let $Q_{i,j} \equiv Q(\vct x_{i,j})$ and define
+a parameter $\eta>0$.  This threshold parameter is tuned such that the quality
+function will detect all the kinks.
+
+The quality function is used to define a direction function,
+\begin{equation}
+  \vct D(\vct x_{i,j}) = (D_x(\vct x_{i,j}), D_y(\vct x_{i,j})),
+\end{equation}
+where
+\begin{equation}
+  D_x(\vct x_{i,j}) = \begin{cases}
+    -1 & \text{if $Q_{i-1,j}<\eta$ and $Q_{i+1,j}\geq\eta$,} \\
+     1 & \text{if $Q_{i-1,j}\geq\eta$ and $Q_{i+1,j}<\eta$,} \\
+     0 & \text{if $Q_{i-1,j}<\eta$ and $Q_{i,j}<\eta$ and $Q_{i+1,j}<\eta$,} \\
+     0 & \text{if $Q_{i-1,j}\geq\eta$ and $Q_{i,j}\geq\eta$ and
+         $Q_{i+1,j}\geq\eta$,} \\
+     4 & \text{otherwise.}
+  \end{cases}
+  \label{eq:dirfunc}
+\end{equation}
+$D_y(\vct x_{i,j})$ is defined in a similar manner.  If $D_x(\vct x_{i,j})
++ D_y(\vct x_{i,j}) > 2$, then $\vct D(\vct x_{i,j})$ is chosen as the vector
+normal to $\grad\varphi(\vct x_{i,j})$.  It is normalized, and the sign is
+chosen such that it points in the direction of the best quality.  See
+\cite{Macklin05} for more details.
+
+The DDS is then defined as
+\begin{equation}
+  \partial_x f_{i,j} = \begin{cases}
+    \frac{f_{i,j} - f_{i-1,j}}{\Delta x}    & \text{if $D_x(x_i,y_j) = -1$,} \\
+    \frac{f_{i+1,j} - f_{i,j}}{\Delta x}    & \text{if $D_x(x_i,y_j) =  1$,} \\
+    \frac{f_{i+1,j} - f_{i-1,j}}{2\Delta x} & \text{if $D_x(x_i,y_j) =  0$,}
+  \end{cases}
+  \label{eq:Ddifference}
+\end{equation}
+and similarly for $\partial_y f_{i,j}$, where $f_{i,j}$ is a piecewise smooth
+function.  The DDS is equivalent to using central differences in smooth areas
+and one-sided differences in areas close to the kinks.
+
+\subsection{Curve-fitting discretization method}
+\label{sec:curvature-curve-fitting}
+The curve-fitting discretization method (CFDM) was first presented
+in~\cite{Lervag11} and is based on the method by \citet{Macklin06}.  The main
+idea is to identify kink regions with the quality function \eqref{eq:quality},
+and to use a curve parametrisation of the closest interface to calculate the
+curvature in regions where the quality function is larger than the threshold
+parameter, $\eta$.
+
+The CFDM applied to the curvature or the normal vector at the grid point $\vct
+x_{i,j}$ can be summarized as follows.  See also \cref{fig:cfdm}, which shows
+an example of the CFDM used at $\vct x_{i,j}$.
+\begin{enumerate}
+  \item If the quality of the level-set function in the neighbourhood of $\vct
+    x_{i,j}$ is good, that is
+    \[
+      Q(\vct{x}_{n,m}) \le \eta \; \forall (n,m) \in [i-1,i+1]\times[j-1,j+1],
+    \]
+    then we use a standard discretization.  Otherwise continue to the next
+    step.
+  \item Locate the closest interface, $\Gamma$.
+  \item Find a set of points on the located interface, $\vct x_1, \dots, \vct
+    x_n \in \Gamma$.
+  \item Create a parametrisation $\vct \gamma(s)$ of the points $\vct x_1,
+    \dots, \vct x_n$.
+  \item Use the parametrisation $\vct \gamma(s)$ to calculate a local level-set
+    function.
+  \item Use a standard discretization of the local level-set function to
+    calculate the curvature or the normal vector.
+\end{enumerate}

+\subsection{Local level-set extraction method}
+\label{sec:lolex}
+The local level-set extraction (LOLEX) method is based on the method presented
+by \citet{Salac08}, here called the SLM.  It was found that the latter method
+was insufficient, because it did not treat all the kink problems.  The LOLEX
+method is therefore a further development of the SLM, in that it handles the
+kink regions in a more general manner.
+
+The LOLEX method applied to the curvature or the normal vector at a grid point
+$\vct x_{i,j}$ is summarized by the following algorithm.  The algorithm is
+presented with 2D notation for clarity, and extends easily to 3D.  See also
+\cref{fig:lolex}, which gives a simple example of the procedure.
+\begin{enumerate}
+  \item If the quality in the neighbourhood of $\vct x_{i,j}$ is good, that is
+    \[
+      Q(\vct{x}_{n,m}) \le \eta \; \forall (n,m) \in [i-1,i+1]\times[j-1,j+1],
+    \]
+    then we use a standard discretization.  Otherwise continue to the next
+    step.
+  \item Copy a small, local square centred around $\vct x_{i,j}$ from the
+    level-set function $\varphi$ into a local array $\varphi_\text{loc}$.
+  \item Identify and enumerate all the \emph{bodies} in the local array
+    $\varphi_\text{loc}$.  A \emph{body} is here defined as a set of
+    neighbouring points where $\varphi_\text{loc}<0$, see \cref{fig:lolex}.
+    There will be $n\geq 0$ bodies in any given $\varphi_\text{loc}$ array.
+  \item If no body is identified, that is, if $n=0$, then use a standard
+    discretization with the global level-set function $\varphi$.  Otherwise
+    continue to the next step.
+  \item For each body $n$, extract the relevant parts of $\varphi_\text{loc}$
+    into an array $\varphi_\text{loc}^n$.  If necessary, extrapolate values to
+    ghost cells.
+  \item For each body, $n$, reinitialize $\varphi_\text{loc}^n$.
+  \item At this step, all the bodies in the local grid have their own
+    local level-set functions that have been reinitialized to proper
+    signed-distance functions.  Due to the separation of the bodies, there
+    are no longer any kinks.
+  \item Use the standard discretization of the curvature and the normal
+    vector at the local level-set function that represents the body that is
+    closest to $\vct x_{i,j}$.

+We first gave a brief introduction to the level-set method, which is used to
+capture the interface.  We then presented the spatial and temporal
+discretization methods, including a brief overview of the projection methods
+that were used to decouple the pressure from the Navier-Stokes equations.  In
+the final section, we presented the new methods for calculating the curvature

+\chapter{The diffuse-domain approach}
+\label{chap:diffuse-domain}
+In the previous chapters, we have considered the modelling of two-phase flows,
+and in particular methods for calculating the curvature and normal vector with
+the level-set method in a reliable manner.  In this chapter, we consider
+a different problem of a more general nature:  How to solve partial
+differential equations (PDEs) in complex domains.  In particular, we consider
+an extension of a diffuse-domain method (DDM) by a high-order correction term
+that gives increased accuracy with respect to interface-width refinements.
+
+We begin with a short introduction to the diffuse-domain approach.  We then
+outline how it can be used to derive a DDM for the steady reaction-diffusion
+equation with Neumann boundary conditions.  Next, we continue with a brief
+introduction to the method of matched asymptotic expansions.  Finally, we
+introduce the high-order correction term derived in Paper~E and show that the
+resulting DDM converge with second order in the diffuse-interface width to the
+original problem.  The analysis also shows that the correction term is not
+necessary for second-order convergence.
+
+\section{Introduction}
+There exist several methods for solving PDEs in complex domains.  Most of them
+have in common that they require tools or methods that are not frequently
+available in standard finite-element or finite-difference software packages.
+Examples of such methods include the immersed-interface method
+\cite{LeVeque94}, the matched interface and boundary method \cite{Zhou06}, the
+extended and composite finite-element method \cite{Dolbow09}, embedded boundary
+methods \cite{Johansen98}, cut-cell methods \cite{Ji06}, and ghost-fluid
+methods \cite{Fedkiw99}.  A different approach, known as the fictitious domain
+method~\cite{Glowinski94,Glowinski96} or the domain imbedding
+method~\cite{Buzbee71}, either augments the original system with equations for
+Lagrange multipliers to enforce the boundary conditions, or use the penalty
+method to enforce the boundary conditions weakly.  For a more complete list of
+references, see Paper~E.
+
+The DDM is an alternative method for solving PDEs in complex domains.  The main
+idea is to use an implicit representation of the boundary, where the sharp
+boundary is replaced by a diffuse layer.  The PDEs are then reformulated on
+a larger, regular domain, and the boundary conditions are incorporated via
+source terms in the diffuse layer.  When the thickness of the diffuse layer is
+reduced, these source terms tend towards singular source terms.  The resulting
+PDEs can then be solved with the use of standard tools and methods.
+
+The diffuse-domain approach was first introduced by \citet{Kockelkoren03} to
+study diffusion inside a cell with homogeneous Neumann boundary conditions at
+the cell boundary.  It was later used by \citet{Li09} to develop a DDM for
+solving PDEs in complex evolving domains with Dirichlet, Neumann and Robin
+boundary conditions, which is hereafter called the DDM1.  The DDM1 has been
+used by \citet{Teigen09-b}, who modelled bulk-surface coupling of material
+quantities on a deformable interface.  It was also used by \citet{Aland10} to
+simulate incompressible two-phase flows in complex domains in 2D and 3D, and by
+\citet{Teigen11} to study two-phase flows with soluble surfactants.
+
+An analysis of the error behaviour of the diffuse-domain approach was done by
+\citet{Franz12} for a diffuse-domain approximation of an elliptic problem with
+Dirichlet boundary conditions.  They considered the infinity norm of the
+difference of the approximated solution and the exact solution, and their
+analysis shows that the approximation quality is of order one in the interface
+width.
+
+In Paper~E, we present the DDM2, which is an extension of the DDM1 by
+a high-order correction term.  The DDM2 is derived for elliptic problems with
+Neumann and Robin boundary conditions, and it is shown to be asymptotically
+second-order accurate in the interface width.  However, the analysis in Paper~E
+is somewhat lacking in that it assumes that the DDM1 is only first-order
+accurate.  In the following sections, we extend the analysis of Paper~E and
+show that the DDM1 is also second-order accurate.  The analysis is shown for
+the steady reaction-diffusion equation with Neumann boundary conditions, but
+the same technique also applies for the corresponding Robin problem.
+
+\section{The DDM for a Neumann problem}
+Consider the steady reaction-diffusion equation with Neumann boundary
+conditions,
+\begin{equation}
+  \begin{alignedat}{2}
+    \lapl u - u  &= f        & \txin D, \\
+    \ndot\grad u &= g \qquad & \txon \partial D,
+  \end{alignedat}
+  \label{eq:ddan}
+\end{equation}
+where $f$ and $g$ are given.  Let $\chi_D$ be the characteristic function of
+$D$,
+\begin{equation}
+  \chi_D = \begin{cases}
+    1 & \text{if $x\in D$,} \\
+    0 & \text{if $x\notin D$.}
+  \end{cases}
+\end{equation}
+The main idea with the diffuse-domain approach is to extend the original
+equation \eqref{eq:ddan} into a larger and regular domain $\Omega\supset D$, as
+depicted in \cref{fig:ddadomain}.  The extension can be written as
+\begin{equation}
+  \div(\chi_D\grad u) - \chi_D u + \text{BC} = \chi_D f,
+  \label{eq:ddm}
+\end{equation}
+where BC is a singular source term that represents the physical boundary
+condition on $\partial\Omega$.

+\end{figure}
+
+The characteristic function is typically approximated by the phase-field
+function,
+\begin{equation}
+  \chi_D \simeq \phi(\vct x,t) = \frac{1}{2} \left( 1
+  - \tanh \left( \frac{3r(\vct x,t)}{\epsilon} \right) \right),
+  \label{eq:characteristic}
+\end{equation}
+where $\epsilon$ is the interface width and $r(\vct x,t)$ is the
+signed-distance function with respect to the boundary $\partial D$, which is
+taken to be negative inside $D$.
+
+The main difficulty with the diffuse-domain approach is the derivation of
+approximations for the boundary condition term BC.  \citet{Li09} give four
+approximations that are shown to converge asymptotically with first order in
+$\epsilon$ to the original equation when $\epsilon$ is decreased.  In the
+following we consider the approximation
+\begin{equation}
+  \text{BC} \simeq |\grad\phi| g.
+  \label{eq:bc1}
+\end{equation}
+If we combine the above approximations \eqref{eq:characteristic} and
+\eqref{eq:bc1}, we get a DDM1 equation for \eqref{eq:ddan},
+\begin{equation}
+  \div\left(\phi\grad u\right) - \phi u +  |\grad\phi| g = \phi f.
+  \label{eq:ddm1}
+\end{equation}
+
+\section{The method of matched asymptotic expansions}
+The following is a brief introduction to the method of matched asymptotic
+expansions, which is used to show that a given diffuse-domain approximation
+converges to the original problem when the interface width is decreased.  More
+details can be found in Paper~E and in \cite{Pego88}.
+
+Let $u$ be some diffuse-domain variable.  The asymptotic convergence of a given
+diffuse-domain approximation can be shown through expansions of the
+diffuse-domain variables in powers of the interface thickness $\epsilon$ in
+regions close to and far from the interface.  For example, the expansions of
+$u$ are
+\begin{align}
+  u(\vct x)        &= \sum_{k=0}^\infty \epsilon^k      u^{(k)}(\vct x), \\
+  \hat u(z,\vct s) &= \sum_{k=0}^\infty \epsilon^k \hat u^{(k)}(z,\vct s),
+\end{align}
+where $u(\vct x)$ and $\hat u(\vct s,z)$ denote the outer and inner expansions,
+respectively.  Here $z$ is a stretched variable,
+\begin{equation}
+  z = \frac{r(\vct x)}{\epsilon},
+\end{equation}
+where $r$ is the signed distance from the point $\vct x$ to $\partial D$ and is
+taken to be negative inside $D$.  Further, $z$ and $\vct s$ form a local
+coordinate system such that
+\begin{equation}
+  \vct x(\vct s,z) = \vct X(\vct s) + \epsilon z\vct n(\vct s),
+\end{equation}
+where $\vct X(\vct s)$ is a parametrisation of the interface, $\vct n(\vct s)$
+is the interface normal vector, and $z$ is a stretched variable.
+
+When the inner and outer expansions are found, they are matched in a region
+where both solutions are valid and where $\epsilon z = \bigo 1$, see
+\cref{fig:regions}.  The outer solution is then evaluated in the inner
+coordinates, which leads to a set of matching conditions that must hold when
+$\epsilon\to 0$.  If we consider $\epsilon$ to be fixed and let $z \to
+\pm\infty$, we get the following asymptotic matching conditions:
+\begin{equation}
+  \label{eq:match1}
+  \zlimpm \hat u^{(0)}(z,\vct s) = u^{(0)}(\vct s),
+\end{equation}
+and as $z \to \pm\infty$,
+\begin{align}
+  \label{eq:match2}
+  \hat u^{(1)}(z,\vct s) &= u^{(1)}(\vct s)
+    + z\ndot\grad u^{(0)}(\vct s) + \smallo 1, \\
+  \begin{split}
+    \hat u^{(2)}(z,\vct s) &= u^{(2)}(\vct s)
+      + z\ndot\grad u^{(1)}(\vct s) \\
+      &\quad + \frac{z^2}{2} (\ndot\grad)\grad u^{(0)}(\vct s)\cdot\vct n
+      + \smallo 1.
+    \label{eq:match3}

+\end{figure}
+
+We remark that the inner expansion is used to obtain the boundary condition on
+$\partial D$, and that the outer solution is used to obtain the sharp-interface
+equation inside the physical domain $D$.
+
+To show that a given DDM approximation converges with second order, one must
+show that the order-one term of the outer solution of the DDM equation is zero
+in $D$.  As an example, we consider the outer solution of the DDM1 equation
+\eqref{eq:ddm1}, which is
+\begin{equation}
+  \begin{split}
+    \lapl u^{(0)} - u^{(0)} &= f, \\
+    \lapl u^{(1)} - u^{(1)} &= 0, \\
+    \lapl u^{(k)} - u^{(k)} &= 0,\qquad k = 2,3,\dots.
+  \end{split}
+  \label{eq:ddm_outer}
+\end{equation}
+For the solution to be asymptotically second order, that is $u = u^{(0)}
++ \bigo{\epsilon^2}$, we must have that $u^{(0)}$ satisfies the original
+problem \eqref{eq:ddan} and that $u^{(1)}=0$.  Thus the inner expansion must
+yield a boundary condition for $u^{(1)}$ to enforce $u^{(1)}=0$.
+
+\section{Asymptotic analysis of the DDM1 and the DDM2}
+\label{sec:DDM2}
+In Paper~E we present the DDM2, which extends the DDM1 \eqref{eq:ddm1} with
+a high-order correction term,
+\begin{equation}
+  \div\left(\phi\grad u\right) - \phi u +  |\grad\phi| g
+    + r|\grad\phi|\left(f - \kappa  g - \lapls u + u\right) = \phi f.
+  \label{eq:ddm2}
+\end{equation}
+Here $r|\grad\phi|\left(f - \kappa  g - \lapls u + u\right)$ is the
+correction term, $\kappa$ is the curvature of the boundary $\partial D$, and
+$\lapls u$ is the surface Laplacian of $u$, which can be defined as
+\begin{equation}
+  \lapls u \equiv
+  \left( I - \vct n\otimes\vct n \right)
+        \div \left( I - \vct n\otimes\vct n \right)\grad u,
+\end{equation}
+where $I$ is the identity matrix and $\vct n$ is the normal vector.  The
+curvature can be calculated from the phase-field function
+\eqref{eq:characteristic} as
+\begin{equation}
+  \kappa = -\div\frac{\grad\phi}{|\grad\phi|}.
+\end{equation}
+
+In the following, we use the method of matched asymptotic expansions to show
+that the DDM1 \eqref{eq:ddm1} and the DDM2 \eqref{eq:ddm2} are both
+second-order approximations of \eqref{eq:ddan} in $\epsilon$.  First, it is
+easy to see that the outer expansions of both approximations are given by
+\eqref{eq:ddm_outer}.
+
+Next, we consider the inner expansion of the DDM2 \eqref{eq:ddm2}, which is
+\begin{multline}
+  \frac{1}{\epsilon^2}\left(\phi\hat u_z\right)_z
+  + \frac \kappa \epsilon \phi\hat u_z
+  + \phi\lapls \hat u
+  - \phi\hat u \\
+  - \frac 1 \epsilon \phi_z g
+  - z\phi_z\left(\hat u + \hat f - \kappa g - \lapls\hat u\right)
+  = \phi \hat f.
+  \label{eq:ddm_inner}
+\end{multline}
+We expand $\hat u(z,\vct s)$ in powers of $\epsilon$ and collect the lowest
+order terms,
+\begin{equation}
+  \left(\phi\hat u_z^{(0)}\right)_z = 0.
+\end{equation}
+If we integrate over all $z$, we get that $\hat u_z^{(0)} = 0$.  The next order
+terms of~\eqref{eq:ddm_inner} then give
+\begin{equation}
+  \left(\phi\hat u_z^{(1)}\right)_z = \phi_z g,
+\end{equation}
+and again we integrate, which gives that
+\begin{equation}
+  \phi\hat u_z^{(1)} = \phi g + C
+  \label{eq:uz1}
+\end{equation}
+where the constant $C$ must be zero, since $\lim_{z\to\infty}\phi(z) = 0$.  Now
+consider the limit $z\to-\infty$ and use the matching condition
+\eqref{eq:match2} to get
+\begin{equation}
+  \ndot\grad u^{(0)} = g.
+\end{equation}
+Thus $u^{(0)}$ satisfies the original problem at least to first order in
+$\epsilon$.  This shows that both DDM1 and DDM2 are first-order approximations
+of the sharp-interface problem.
+
+To obtain the result for the next order, we need to apply the derivative of
+the matching condition \eqref{eq:match3},
+\begin{equation}
+  \hat u_z^{(2)} = \ndot\grad u^{(1)}
+      + z (\ndot\grad)\grad u^{(0)}\cdot\vct n.
+  \label{eq:match3_z}
+\end{equation}
+Further, we use that $u^{(0)}$ satisfies
+\begin{equation}
+  \lapl u^{(0)} - u^{(0)} = f^{(0)},
+\end{equation}
+and that the Laplacian may be decomposed as
+\begin{equation}
+  \lapl u = (\ndot\grad)\grad u\cdot\vct n + \kappa\ndot\grad u + \lapls u,
+\end{equation}
+to get
+\begin{equation}
+  (\ndot\grad)\grad u^{(0)}\cdot\vct n
+    = u^{(0)} + f^{(0)} - \kappa g - \lapls u^{(0)}.
+  \label{eq:ngradun}
+\end{equation}
+Now insert \eqref{eq:ngradun} into \eqref{eq:match3_z} and use the matching
+condition \eqref{eq:match1} to obtain a modified matching condition,
+\begin{equation}
+  \hat u_z^{(2)} - z\left(\hat u^{(0)} + \hat f^{(0)}
+        - \kappa g - \lapls \hat u^{(0)}\right)
+  = \ndot\grad u^{(1)}.
+  \label{eq:match3_z2}
+\end{equation}
+
+We are now ready to consider the zeroth order terms,
+\begin{multline}
+  \label{eq:o1}
+  \left(\phi\hat u^{(2)}_z\right)_z
+  + \phi\kappa\hat u_z^{(1)}
+  + \phi\lapls \hat u^{(0)}
+  - \phi\hat u^{(0)} \\
+  - z\phi_z\left(\hat u^{(0)}
+      + \hat f^{(0)} - \kappa g - \lapls\hat u^{(0)}\right)
+  = \phi \hat f^{(0)}.
+\end{multline}
+The modified matching condition \eqref{eq:match3_z2} motivates that we subtract
+and add the term
+\[
+  \bigg(z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\bigg)_z
+\]
+to \eqref{eq:o1}, which gives
+\begin{multline}
+  \bigg(\phi\hat u_z^{(2)}
+    - z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\bigg)_z \\
+  + \bigg(z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\bigg)_z \\
+  + \phi\kappa\hat u_z^{(1)}
+  + \phi\lapls \hat u^{(0)}
+  - \phi\hat u^{(0)} \\
+  - z\phi_z\left(\hat u^{(0)}
+      + \hat f^{(0)} - \kappa g - \lapls\hat u^{(0)}\right)
+  = \phi \hat f^{(0)}.
+\end{multline}
+We expand the terms and use \eqref{eq:uz1},
+\begin{multline}
+  \bigg(\phi\hat u_z^{(2)}
+    - z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\bigg)_z \\
+  + \cancel{\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)} \\
+  + z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)_z \\
+  + \cancel{\phi\kappa g
+  + \phi\lapls \hat u^{(0)}
+  - \phi\hat u^{(0)}}
+  = \cancel{\phi \hat f^{(0)}},
+  \label{eq:o2}
+\end{multline}
+or
+\begin{multline}
+  \bigg(\phi\hat u_z^{(2)}
+    - z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\bigg)_z \\
+  + z\phi\left(\cancel{\hat u_z^{(0)}} + \hat f_z^{(0)}
+      - \cancel{(\kappa g)_z}
+      - \cancel{\lapls \hat u_z^{(0)}}\right) = 0.
+\end{multline}
+If we assume that $\hat f_z^{(0)}$, we get
+\begin{equation}
+  \bigg(\phi\hat u_z^{(2)}
+    - z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\bigg)_z = 0.
+  \label{eq:o3}
+\end{equation}
+Finally, we integrate the left-hand side and take the limit,
+\begin{align}
+  \nonumber
+  \eint{\bigg(\phi\hat u_z^{(2)}
+    &- z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+     - \lapls \hat u^{(0)}\right)\bigg)_z} \\
+  \nonumber
+  &= \ejmp{\phi\hat u_z^{(2)}
+    - z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)} \\
+  \nonumber
+  &= -\zlimm{\left(\hat u_z^{(2)}
+    - z\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\right)} \\
+  &= -\ndot\grad u^{(1)},
+\end{align}
+thus
+\begin{equation}
+  \ndot\grad u^{(1)} = 0.
+  \label{eq:ngradu1}
+\end{equation}
+Combined with \eqref{eq:ddm_outer}, this shows that $u^{(1)}=0$, and so DDM2
+converges asymptotically with second order to the original problem.
+
+The analysis above also holds for DDM1, except instead of \eqref{eq:o3} we get
+\begin{multline}
+  \bigg(\phi\hat u_z^{(2)}
+    - z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\bigg)_z \\
+  = - z\phi_z \left(\hat u^{(0)} + \hat
+        f^{(0)} - \kappa g - \lapls \hat u^{(0)}\right)
+  = - z\phi_z D,
+  \label{eq:o4}
+\end{multline}
+where $D$ is independent of $z$.  Now we use that
+\begin{equation}
+  \phi_z = -(3 \sech^2 3z)/2,
+\end{equation}
+which follows from the definition of the phase-field function
+\eqref{eq:characteristic}.  We integrate the right-hand side, which gives
+\begin{equation}
+  D\eint{z\phi_z} = -D\frac 3 2\eint{z\sech^2 3z} = 0.
+\end{equation}
+Thus DDM1 is also second order in $\epsilon$.
+
+The difference between the DDM1 and the DDM2 is therefore that the correction
+term with the DDM2 directly cancels the term on the right-hand side in
+\eqref{eq:o4}.  This should give an increase of accuracy, but the convergence
+order remains the same.
+
+The analysis for the corresponding Robin problem is essentially the same as the
+above.  In Paper~E, the DDM1 and DDM2 are compared for several elliptic
+problems with both Neumann and Robin boundary conditions.  The results of
+Paper~E show that the correction term in the DDM2 leads to an increase of
+accuracy and that both DDM1 and DDM2 converge with second-order accuracy.
+
+\section{Summary}
+In this chapter, we have given a brief introduction to the diffuse-domain
+method (DDM).  We considered a steady reaction-diffusion equation with Neumann
+boundary conditions \eqref{eq:ddan} and two DDM approximations:  DDM1
+\eqref{eq:ddm1} and DDM2 \eqref{eq:ddm2}.  The DDM2 is an extension of DDM1 by
+a high-order correction term, and was first derived in Paper~E.
+
+Next, we gave an outline of the method of matched asymptotic expansions, and we
+used it to show that both the DDM1 and the DDM2 converged asymptotically with
+second order in the diffuse-interface width to the original equation
+\eqref{eq:ddan}.  The analysis shows that the correction term in the DDM2 leads
+to a cancellation in the asymptotic expansions.  By doing the integration, we
+see that this cancellation is not necessary for obtaining the second order
+convergence.

+\section[Paper A]{Paper A:  Calculation of interface curvature with the
+  level-set method}
+Karl Yngve Lervåg.  Published in \emph{MekIT'11 - 6th National Conference on
+  Computational Mechanics, Trondheim}, 2011.  ISBN: 978-82-519-2798-7.
+
+In this paper I address a problem with the calculation of the interface
+curvature with the level-set method, cf.\ \cref{sec:curvature}.  The curvature
+can be calculated from the level-set function, $\phi$, as
+\begin{equation}
+  \kappa = \div\vct n = \div\frac{\grad\phi}{|\grad\phi|}.
+\end{equation}
+It is typically discretized by standard methods such as the second-order
+central-difference scheme (CD-2), and interpolated to the interface where
+needed \cite{Osher88,Kang00,Osher03}.  However, the level-set function as
+a signed-distance function will tend to have kinks where its gradient is
+discontinuous.  The standard methods may lead to large errors in the curvature
+close to these regions, which in turn may lead to errors in the surface tension
+force.
+
+The main contribution of this paper is a new curve-fitting discretization
+method (CFDM) for the curvature (see \cref{sec:curvature-curve-fitting}).  The
+method is based on the approach developed by \citet{Macklin06}.  It differs in
+that it uses a cubic Hermite spline parametrisation of the interface, and that
+the curvature values are calculated on the grid and then interpolated to the
+interface as opposed to using a localised grid centred at the interface as in
+\cite{Macklin06}.

+\end{figure}
+
+The CFDM is tested and compared with the CD-2 for two test cases, and it is
+shown to yield better results in both cases.  \Cref{fig:A1} shows one of these
+results, where the calculated curvature values are compared.  In the example,
+a cylindrical drop impacts on a liquid film.  The figure shows that the CD-2
+leads to large errors in the curvature calculations in the kink regions, that
+is, the red and dark blue regions in \cref{fig:A1a} near the liquid film.
+These errors are not present with the new method, cf.\ \cref{fig:A1b}.
+
+\paragraph{My contribution:}  I developed the method and implemented it into

+\section[Paper B]{Paper B:  Curvature calculations for the level-set method}
+Karl Yngve Lervåg and Åsmund Ervik.  Published in \emph{ENUMATH 2011}
+proceedings volume, Springer, 2013.  ISBN: 978-3642331336.
+
+This paper is a continuation of Paper A.  The main contribution in this paper
+is a comparison of different methods for calculating the curvature in a robust
+manner with the level-set method in the kink regions.  In particular, the
+CFDM\footnote{The method is called LM in the paper.  Here CFDM is used, in
+  order to be consistent with the rest of the thesis.} that was presented in
+Paper A is compared with Macklin and Lowengrub's method (MLM)~\cite{Macklin06}.
+In addition, the method is compared with the second-order central-difference
+scheme (CD-2) and the more recent method presented by \citet{Salac08}, here
+called Salac and Lu's method (SLM).
+
+The main result in the paper is shown in \cref{fig:B1}, which shows
+a comparison of the methods for a case where two drops collide in a 2D shear
+flow.  In particular, it shows snapshots of the evolution of the interfaces and
+the curvature at times $t=\SI{2.30}{s}$, $t=\SI{2.75}{s}$, and
+$t=\SI{3.10}{s}$.  The results show that all of the improved methods, that is
+MLM, CFDM, and SLM, handle the kink region in a more reliable manner than CD-2.
+The reason that the result with MLM differs from those with CFDM and SLM might
+be that it uses a localised grid centred at the interface to calculate the
+curvature, which means that it does not need to use interpolation of the
+curvature from the grid to the interface.  Note that the difference is mainly
+that the MLM results in slightly earlier coalescence in the given case.

+\section[Paper C]{Paper C:  Calculation of the interface curvature and normal
+  vector with the level-set method}
+Karl Yngve Lervåg, Bernhard Müller, and Svend Tollak Munkejord.  Published in
+Computers and Fluids, volume 84 (2013), 218--230.
+
+Paper A presented the curve-fitting discretization method (CFDM) for the
+calculation of the curvature with the level-set method.  The method was
+designed to be robust in the calculation of the curvature in kink regions, that
+is regions where the gradient of the level-set function is not smooth.  This
+paper presents the details of the CFDM and applies it to the calculation of
+both the curvature and the normal vector.
+
+In the paper we compare the CFDM with the second-order central-difference
+scheme (CD-2) for several test cases.  In the first case, we consider the
+curvature calculations for a nontrivial geometry that includes some kink
+regions.  This is a static test case with no flow, and the results show that
+the CD-2 leads to large errors for the curvature calculations in areas close to
+kink regions and that these errors are not present with the CFDM.
+
+In the following two cases, we consider the collision of two drops in a 2D
+shear flow and in an axisymmetric flow.  These cases show that the errors in
+the curvature calculations in the kink regions with the CD-2 lead to errors in
+the pressure that prevents coalescence.  These errors are prevented with the
+CFDM.  The curvature and the evolution of the interfaces for the axisymmetric
+case are shown in \cref{fig:C1,fig:C2}.  As in the earlier results of Papers
+A and B, the figures show that the errors in the curvature calculation with
+CD-2 prevent coalescence, in this case leading to a slower coalescence process.

+\section[Paper D]{Paper D:  A robust method for calculating interface curvature
+  and normal vectors using an extracted local level set}
+Åsmund Ervik, Karl Yngve Lervåg, and Svend Tollak Munkejord.  Submitted to
+Journal of Computational Physics, 2013.
+
+In this paper we present an alternative method for the calculation of the
+curvature and the normal vector of an interface with the level-set method in
+kink regions, hereafter called the local level-set extraction (LOLEX) method.
+The method is based on a method presented by \citet{Salac08} (SLM), who handle
+the kink region by extracting different bodies of a domain into separate
+level-set functions.  This procedure removes most of the kink regions, but it
+does not handle kink regions that are due to complex interfaces of single
+bodies.  Our method extends the SLM by making it local.  That is, we only
+consider the local area around the point for which we are calculating the
+curvature or the normal vector.  This leads to a method that is more generally
+applicable, as shown in \cref{fig:D1}.  The figure shows a comparison between
+the LOLEX method, the SLM, and the standard central differences (CD-2).  CD-2
+leads to curvature spikes at the kink regions, as explained in
+\cref{sec:curvature}.  The SLM gives a better result for the kink regions
+around the rightmost disc.  However, since the other two discs are connected to
+each other and to the film, they are considered to be the same body and are
+extracted into the same level-set function.  Several kink regions are therefore
+not removed.  Since the LOLEX method only considers the local area, as
+explained in \cref{sec:lolex}, it is able to handle all the kink regions in
+a robust manner.

+    negative and red is positive.}
+  \label{fig:D1}
+\end{figure}
+
+The LOLEX method has proven to be a good alternative to the CFDM presented in
+Paper A.  Its main advantages are that it does not rely on complex algorithms
+as used in the CFDM or by \citet{Macklin06}, and that the method easily extends
+to 3D as demonstrated in the paper in Section~4.4.
+
+In the previous papers A--C, we used the DP1 projection method by
+\citet{Hansen05}.  In this paper we instead used the more standard Chorin
+projection method.  These methods differ in that the DP1 assumes
+\begin{equation}
+  \div\left(\pdt{\vct u}\right) = 0.
+\end{equation}
+When compared with the Chorin method, this assumption becomes equivalent to
+assuming that $\div\vct u^{n} = 0$ in \eqref{eq:PoissonChorin}.  That is, the
+DP1 assumes that the initial velocity field is divergence free.  We have found
+that the DP1 works well in most cases, but that it is less robust than the
+Chorin method.  In particular, the Chorin method is not equally affected by
+errors in the curvature calculations in kink regions.  In other words, the
+difference between using a standard discretization and an improved
+discretization of the curvature is smaller with the Chorin method than with the
+DP1.
+
+The LOLEX method is used for several test cases and compared with CD-2.  The
+results indicate that even though we use the Chorin projection method, the
+LOLEX method outperforms CD-2 in all cases.  Further, the results agree well
+with experiments, except for time instants, as shown in \cref{fig:D2}.  The
+exact reason why the time instants do not match is not known, but one reason
+may be that the initial condition of the numerical simulation did not match the
+corresponding state of the experiment.

+    from~\cite{Zhao11}, Copyright (2011), with permission from Elsevier.}
+  \label{fig:D2}
+\end{figure}
+
+When we study the drop-film collision processes, an important consequence of
+the error in the curvature calculation is a loss of kinetic energy.  This can
+be seen in \cref{fig:D3}, which compares the LOLEX method with CD-2 at two
+different stages of the collision process.  The figure also compares two
+different frequencies of reinitialization of the level-set function:  Every
+7 time steps ((a) and (c)) and every single time step ((b) and (d)).  The
+figure shows that the error in the curvature calculation with CD-2 leads to
+a shorter neck, as seen in \cref{fig:D3}, (c) and (d).  The error is larger for
+the higher frequency of reinitialization.  The results indicate that CD-2 leads
+to a loss of kinetic energy during the collision process when compared with the
+LOLEX method.  The LOLEX method is not significantly affected by the amount of
+reinitialization, and the kink region does not affect the curvature
+calculation, cf.\ \cref{sec:lolex}.  Thus the pressure field is more sensible,
+as seen in \cref{fig:D3} (a) and (b).  Finally, we remark that some authors
+have noted \cite{Blanchette06} that the height of the neck and the dynamics of
+the capillary waves are important factors for the partial coalescence
+mechanism, which implies that the correct calculation of the curvature is
+important to capture the correct physical behavior.

+\section[Paper E]{Paper E:  Towards a second-order diffuse-domain approach for
+  solving PDEs in complex geometries}
+Karl Yngve Lervåg and John Lowengrub.  Submitted to Communications in Math.
+Sciences, 2013.
+
+\citet{Li09} developed a diffuse-domain method for solving partial-differential
+equations (PDEs) inside complex, dynamic geometries with Dirichlet, Neumann,
+and Robin boundary conditions.  This method is in the following referred to as
+DDM1.  They use the diffuse-domain approach~\cite{Kockelkoren03}, where the
+geometry is represented implicitly and the sharp boundary is replaced by
+a diffuse layer with a fixed interface width.  The original governing equations
+are then reformulated on a larger, regular domain and the boundary conditions
+are incorporated via singular source terms.  The method of matched asymptotic
+expansions is used to show that the reformulated problem converges
+asymptotically to the original problem.
+
+In the present paper, we use the method of matched asymptotic expansions to
+extend the DDM1 with include a high-order correction term in the diffuse
+formulation, cf.\ \cref{sec:DDM2}.  The extension is derived for elliptic
+problems with Neumann and Robin boundary conditions, where the correction term
+is shown to yield an asymptotically second-order accurate approximation of the
+original problem.  The new method is referred to as the DDM2.
+
+The DDM1 and DDM2 are compared for a selection of test problems.  The resulting
+equations were discretized by standard second-order central-difference schemes
+on uniform grids, and solved by a multigrid method.  A red-black Gauss-Seidel
+type iterative method was used as a smoother, see \cite{Wise07}.
+
+In addition to the comparison of DDM1 and DDM2, we compared two different
+approximations of the boundary conditions.  These correspond to different
+diffuse-interface surface delta functions, and for the Neumann boundary
+conditions they are
+\begin{equation}
+  \text{BC1} = |\grad\phi| g,
+\end{equation}
+and
+\begin{equation}
+  \text{BC2} = \epsilon|\grad\phi|^2 g.
+\end{equation}
+The approximations are similar for the Robin boundary condition, although here
+it was found that only BC1 resulted in a valid asymptotically second-order
+accurate DDM2.
+
+Our results show that the global accuracy and convergence of DDM2 is better
+than DDM1, however both methods perform well and the global convergence rate is
+around two for each.  The error was measured as the L$_2$ norm of the
+difference between an analytic solution and the solution $u_\epsilon$ for
+a given interface width, $\epsilon$.
+
+\Cref{fig:E1,fig:E2} show two of the results, the first one with the Neumann
+boundary conditions and the second with the Robin boundary condition.  The
+results indicate that DDM2 performs slightly better than DDM1.  They also show
+that the approximation BC1 gives more accurate results than BC2.  In
+particular, we found that with BC2 we needed much finer grids to obtain
+convergence for a given $\epsilon$.  For the smallest values of $\epsilon$ we
+were not able to refine the grids enough to obtain valid results.

+\chapter{Conclusions and outlook}
+\label{chap:conclusions}
+This thesis has considered two different problems:  The discretization of
+interface curvature and normal vectors with the level-set method and
+a diffuse-domain approach for solving partial-differential equations (PDEs) in
+complex domains.  In the following, some general concluding remarks and
+recommendations for further work are given.
+
+\section*{Conclusions}
+The first part of the thesis considered the modelling of incompressible
+two-phase flow.  The main motivation was to study two-phase flow phenomena that
+are relevant for compact heat exchangers, such as drop-drop and drop-film
+collisions.  In particular, the thesis addressed a challenge with the
+calculation of interface curvature and normal vectors with the level-set
+method.  Two methods were presented to handle the discretization in the kink
+regions: A curve-fitting discretization method (CFDM) and a local level-set
+extraction (LOLEX) method.  Both methods were shown to be robust in the kink
+regions, where the standard central-difference scheme (CD-2) fails.  Of these
+methods, the LOLEX method is the preferred method, because it relies on a less
+complicated algorithm that easily extends to 3D.
+
+CD-2 and the LOLEX method were used for simulations of drop-film collisions
+that were compared with experiments.  The results showed that CD-2 leads to
+errors in the curvature that cause unphysical pressure spikes during the
+coalescence.  The errors are shown to lead to a dissipation of kinetic energy
+during the collision and to a slower coalescence process.  The LOLEX method was
+shown to prevent these unphysical pressure spikes, and to produce to more
+accurate results.
+
+The second part of the thesis considered the diffuse-domain approach for
+solving PDEs in complex domains.  The main contribution, presented in Paper~E,
+was the derivation of an asymptotically second-order diffuse-domain method
+(DDM2) for solving elliptic problems in complex geometries with Neumann and
+Robin boundary conditions.  The new method is an extension by a high-order
+correction term of the method presented in \cite{Li09}, here called DDM1.  The
+DDM1 and DDM2 were compared, and the results indicated that the DDM2 was
+slightly better than the DDM1.
+
+The thesis has expanded on the results of Paper~E with a new asymptotic
+analysis that shows that DDM1 is in fact also asymptotically second order.
+This analysis helps to explain why the performance of DDM2 presented in Paper~E
+is only slightly better than that of DDM1.  As such, the new analysis leads to
+a better understanding of the DDM1 and the DDM2.
+
+\section*{Outlook}
+The following gives an outline of some possibilities for future work.
+\begin{itemize}
+  \item A natural continuation of this work is to perform more in-depth
+    comparisons of simulations with experiments for the drop-film collision
+    phenomenon that was started in Paper~D.  In addition, it would be
+    interesting to study other two-phase flow phenomena that are relevant for
+    heat-exchanger processes, for instance drop-drop collisions or flow across
+    tube bundles.  The latter requires the treatment of more complex boundaries,
+    which can be handled either with the diffuse-domain method or other methods
+    from the literature.
+  \item Paper~C gave a short comparison of the standard discretization method
+    (CD-2), the direction-difference scheme (DDS), and the curve-fitting
+    discretization scheme (CFDM) applied to the calculation of the normal
+    vectors.  The results showed that the CD-2 leads to inaccurate results in
+    the kink regions.  The DDS gives robust and accurate results in most cases,
+    but an example is given where only the CFDM yields an accurate result.
+    However, the impact of inaccurate calculations of the normal vector should
+    be investigated in more detail.  The normal vector is used both for the
+    solution of the level-set equations \eqref{eq:ls_adeq},
+    \eqref{eq:ls_velextr}, and \eqref{eq:ls_reinit}, and for the calculation of
+    the interface jumps \eqref{eq:jump_pressure} and \eqref{eq:jumptens}, so
+    one can expect that large errors in the calculation of the normal vector
+    may lead to large errors in the numerical solution.  This warrants
+    a further study.
+  \item Mass and heat transfer are obviously an important part of the
+    heat-exchanger processes.  The models that have been used in this thesis
+    should therefore be expanded with additional models for heat transfer and

+\chapter{Introduction}
+This thesis considers the mathematical modelling and numerical computation of
+two-phase flows.  It focuses on developing more robust numerical methods to
+calculate the curvature and the normal vector of the interface between the two
+phases.  In addition it considers a diffuse-domain method for solving partial
+differential equations in complex geometries, and it derives an asymptotically
+second-order method for elliptic problems.
+
+\section{Background and motivation}
+Two-phase flows are particular examples of multiphase flows of gas and liquid
+with an interface that separates the two phases.  In the pedantic sense,
+two-phase flow is flow of a single fluid that occurs as two different phases,
+for example steam and water.  However, it is common to be more general, and in
+this thesis we use the term two-phase flow also for immiscible mixtures of
+different fluids, such as water and oil.
+
+Two-phase flows are crucial to a large amount of processes, both in nature and
+in industry.  Examples range from weather phenomena, such as rain drops falling
+through air, to industrial processes, for instance the separation of water from
+oil.  In general, multiphase flow phenomena influence any process where liquids
+and gases are involved.  In the oil and gas industry, most processes are
+two-phase or multiphase flow processes.  Needless to say, the understanding of
+these phenomena is fundamental in the development of new or improved processes.
+
+Consider the international trade of liquefied natural gas (LNG), which is
+a particular branch of the oil and gas industry that has undergone an
+exceptional growth in the last decades.  There is a strong focus both in Norway
+and internationally on producing LNG on large floaters
+(FLNG)\footnote{FLNG facilities do not yet exist, although a facility is under
+  development by Royal Dutch Shell~\cite{Prelude1}.  The construction of this
+  facility was started in 2012, and the first drilling is stated to commence in
+  2013~\cite{Prelude2}.}.  There are a number of both environmental and
+economic advantages of such FLNG facilities.  In particular, FLNG facilities
+would remove the need of long pipelines from the gas fields to the shore, there
+would be no requirement for compression units to pump the gas to the shore, and
+one would not need to construct onshore production facilities.  This would
+significantly reduce the environmental footprint, and would help preserve
+marine and coastal environments.  Since an FLNG facility can be moved to a new
+location when a field has been depleted, it would make it economically viable
+to open up new business opportunities to develop offshore gas fields that would
+otherwise remain stranded.
+
+Moving the LNG production to an offshore facility presents a demanding set of
+challenges.  A particular challenge is that the elements of a conventional LNG
+facility need to fit into an area roughly one quarter the original size.  Heat
+exchangers are among the main challenges in the design and operation of LNG
+plants \cite{Hesselgreaves01}.  Compact and efficient heat exchangers are
+needed to obtain an energy efficient plant with low emissions.  More optimized
+designs require more accurate tools for design and operation.  Such tools can
+only come as a result of an improved physical understanding of the complex
+two-phase flows occurring in the heat exchangers.  This can be achieved by more
+detailed mathematical modelling, together with dedicated laboratory
+observations, cf.\ \cite{Olsen07}.
+
+\section{Overview of methods for two-phase flow simulations}
+In the following, a brief overview is given of different methods for modelling
+two-phase flows where the interface location is known.  In particular, we focus
+on methods that handle the interface evolution.  For more in-depth reviews, see
+for instance \cite{Cristini04,Scardovelli99,Sethian03}.
+
+Interface propagation methods comprise a range of methods that are often
+categorised as either front tracking or front capturing.  Front-tracking
+methods use Lagrangian particles to track the interface
+explicitly~\cite{Tryggvason01}, while front-capturing methods use an Eulerian
+approach to capture the interface implicitly.  Examples of the latter are
+volume-of-fluid methods~\cite{Scardovelli99,Tryggvason11}, phase-field
+methods~\cite{Anderson98,Jacqmin99,Lowengrub98}, and level-set
+methods~\cite{Osher03}.
+
+The main advantages of front-tracking methods are their inherent accuracy and
+that topological changes do not occur without explicit action.  Hence,
+unphysical numerical reconnection does not occur.  This means that if front
+tracking is used for the simulations of two drops that collide, these drops
+will not coalesce due to numerical reconnection or merging.  However, the
+handling of topological changes are challenging, in particular in three
+dimensions~\cite{Shin02}.  Also, there are some issues of numerical
+instabilities, as discussed by \citet{Sethian85} and \citet{Osher88}.
+
+The volume-of-fluid method utilizes a volume-fraction function whose values
+represent the characteristic function of one of the fluid domains.  Its values
+are zero or one, except in those cells cut by the interface.  A considerable
+advantage of the volume-of-fluid method is that it conserves the mass of both
+fluids well.  However, the reconstruction of the interface from volume
+fractions is not simple, and computation of geometric quantities such as the
+interface curvature is not straightforward.  Also, spurious bubbles and drops
+may be created, cf.\ \cite{Lafaurie94}.
+
+The phase-field methods treat the interface in a diffuse manner, where the
+fluid properties, such as density and viscosity, change rapidly but smoothly
+across the interface.  These methods typically solve the coupled
+Cahn-Hilliard/Navier-Stokes equations, where the Cahn-Hilliard equation is
+based on the free energy of an interface~\cite{Cahn57}.  Through this energy
+formulation, one can model more advanced interface physics such as van der
+Waals interactions, electrostatic forces, and fluids with varying
+miscibilities.  However, the phase-field methods require that one resolves very
+small length scales at the interfaces.  This poses a severe restriction on the
+applicability of phase-field methods for two-phase flow, where the length
+scales of the flow are generally much larger than those of the interface.
+
+In this thesis, we have used the level-set method~\cite{Osher88}, which
+implicitly captures the interface as an isocontour of a function defined in the
+entire domain.  The main motivation of this choice is both that the level-set
+method handles topological changes of evolving interfaces automatically,
+cf.~\citet{Sethian03}, and that it is relatively straightforward to implement.
+
+It should be noted that the automatic handling of topological changes is not
+based on physical principles.  For instance, when two interfaces approach each
+other and their distance becomes less than the spacing of the grid, the
+level-set method can no longer resolve both interfaces and so they are merged.
+An important consequence is that the level-set method does not model the
+physics involved in the coalescence process, and in particular in the smaller
+scales of the film-drainage process.  This process involves a wide range of
+length scales, varying from the nanometer scale where van der Waals force are
+active to the length scales of the external flow.  Some effort has been made to
+include the effects of the smaller scales in front-capturing methods,
+cf.~\cite{Nobari96,Tryggvason10}.  Recently, \citet{Kwakkel13} presented
+a level-set/volume-of-fluid method that is coupled with a film-drainage model
+that predicts if and when two colliding droplets will coalesce.  To prevent the
+numerical coalescence, each droplet has its own locally defined level-set
+function.
+
+The level-set method has been used to model several diverse phenomena,
+such as tumour growth~\cite{Macklin06,Macklin05,Macklin08}, propagation of
+wildland fire~\cite{Mallet09}, and computer RAM production~\cite{Melicher08}.
+For a good and thorough introduction to the level-set method, see
+\cite{Osher03}.
+
+A weakness of the level-set method is that it does not conserve the mass of the
+two fluids, in particular in areas of low resolution and/or high curvature.
+Different approaches have been developed to overcome this disadvantage, for
+example the conservative level-set method~\cite{Olsson05,Olsson07}, the
+particle level-set method~\cite{Enright02}, or the coupled
+level-set/volume-of-fluid method~\cite{Sussman00}.
+
+When we use the level-set method to capture the interface for immiscible and
+incompressible two-phase flow simulations, there will be a sharp change in the
+density and viscosity across the interface.  In this thesis we use the
+ghost-fluid method~\cite{Fedkiw99}, which is a sharp-interface method where the
+jumps are included in the spatial discretizations in a sharp manner.  An
+alternative method is the continuous surface-force method introduced by
+\citet{Brackbill92}, where the density and the viscosity are smeared out across
+the interface through a smoothed Heaviside function.
+

+\section{Goal and contribution of the present thesis}
+The main goal of the PhD project has been to develop fundamental knowledge of
+two-phase flow phenomenon that are relevant for compact heat exchangers.
+
+In order to do detailed theoretical studies of phenomena that are relevant for
+compact heat exchangers, we need to consider two-phase flows with mass and heat
+transfer in confined and complex geometries.  One such relevant phenomenon is
+the drop-film collision process \cite{Zhao09}.  Even when restricted to
+isothermal and immiscible flows, this simple phenomenon remains a challenge.
+When the level-set method is used to capture the interface, one must be
+particularly careful about how one calculates the interface curvature and
+normal vector.  For instance, when two drops are in near collision there is
+a kink region in the level-set function between the drops, where the gradient
+is discontinuous, see \cref{fig:curvature-problem}.  This discontinuity may
+lead to large errors in the curvature and the normal vector if it is not taken
+into account in the discretization stencils.

+
+As a step towards computing two-phase flow simulations in confined geometries,
+the thesis has considered the diffuse-domain method~\cite{Li09}.  This is
+a method where partial-differential equations in complex domains are extended
+into larger, regular domains with the use of diffuse approximations of the
+physical boundaries.  The approximations converge asymptotically to the
+original problem when the width of the diffuse boundary is reduced.  With this
+method one can use standard numerical methods to solve equations that
+incorporate complex boundaries.
+
+The main contributions of the present thesis are two new methods to calculate
+the curvature and normal vector in a robust manner with the level-set method.
+These methods are shown to yield more accurate calculations of drop-film and
+drop-drop collisions.  The methods are compared with standard methods and with
+other methods from the literature.
+
+In addition, the thesis presents an extension of a diffuse-domain method by
+a high-order correction term for the solution of elliptic problems in complex
+geometries.  New analysis provided in the thesis improves the understanding of
+the diffuse-domain method, and the derived method is shown to be more accurate
+than the existing diffuse-domain method.
+
+\section{Outline of the thesis}
+The thesis is organised as follows: \Cref{chap:two-phase-flow} gives a brief
+overview of the derivation of the governing equations for two-phase flow.  It
+includes a consideration of the fluid-fluid interface conditions and the
+derivation of a simplified jump tensor for the viscous term at the interface.
+
+\Cref{chap:numerical-methods} gives a detailed description of the numerical
+methods that are used to solve the two-phase flow equations.  In particular, it
+describes the level-set method, which is used to capture the interfaces,
+projection methods that are used to solve the Navier-Stokes equations, and the
+spatial and temporal discretization schemes.  At the end of the chapter, an
+overview of the novel discretization methods for the curvature and the normal
+vector is given.
+
+\Cref{chap:diffuse-domain} gives a short introduction to the diffuse-domain
+method for an elliptic problem with Neumann boundary conditions.  It introduces
+the high-order correction term, and shows that the new method converges
+asymptotically with second-order to the original problem.  The chapter presents
+new analysis that shows that the correction term is not necessary for
+second-order convergence.
+
+In \cref{chap:contributions} the main results of the contributed papers A--E
+are summarized, and the author's contributions are highlighted.  Finally,
+\cref{chap:conclusions} gives concluding remarks and provides an outlook for
+future work.
+
+Full-text versions of the research papers A--E are provided in the Appendices
+at the end of the thesis.

+\chapter{Governing equations for two-phase flow}
+\label{chap:two-phase-flow}
+In this chapter we will give a brief overview of the derivation of the
+governing equations for two-phase flow.  We begin with a consideration of the
+Navier-Stokes equations for single-phase flow.  We then introduce a singular
+surface-force term and derive the Navier-Stokes equations for two-phase flow.
+Finally, we use the Navier-Stokes equations for two-phase flow to derive jump
+conditions at the interface between the phases.
+
+\section{The Navier-Stokes equations for single-phase flow}
+The following is a brief derivation of the Navier-Stokes equations for
+single-phase flows.  For a more thorough derivation of these equations, see for
+instance \citet[§4 and §5]{Aris89} or \citet[Chapter~4]{White03}.
+
+We consider a single-phase, viscous flow in some domain $\Omega$ with boundary
+$\partial\Omega$.  When temperature effects are neglected the flow is described
+by the Cauchy equation
+\begin{equation}
+  \label{eq:cauchy_equation}
+  \rho\left(\cd{\vct u}\right) = \div\tenstr+\rho\vct f,
+\end{equation}
+and the mass conservation equation,
+\begin{equation}
+  \label{eq:cons_of_mass}
+  \pdt\rho + \div(\rho\vct u) = 0.
+\end{equation}
+Here $\rho$ is the fluid density, $\vct u$ is the flow velocity, $t$ is time,
+$\tenstr$ is the stress tensor, $\vct f$ denotes body forces, and $\del$ is
+used to denote the gradient and divergence operators.  The stress tensor for
+Newtonian fluids with zero bulk viscosity is
+\begin{equation}
+  \tenstr = -p\tenI + 2\mu\tenD - \frac 2 3\mu (\trace\tenD) \tenI,
+  \label{eq:viscous_stress_tensor}
+\end{equation}
+where $p$ is the pressure, $\tenI$ is the identity tensor, $\mu$ is the dynamic
+viscosity, and $\trace\tenD$ denotes the trace of the strain-rate tensor
+$\tenD$,
+\begin{equation}
+  \tenD = \frac{1}{2}\left( \grad\vct u + (\grad\vct u)^T \right).
+  \label{eq:deformation_tensor}
+\end{equation}
+For incompressible flow, the mass-conservation equation reduces to
+\begin{equation}
+  \label{eq:navier-stokes-1}
+  \div\vct u = 0,
+\end{equation}
+that is, the velocity field must be divergence free.  If we further assume that
+the viscosity is constant, then it follows that the divergence of the stress
+tensor reduces to
+\begin{equation}
+  \label{eq:stress_tensor}
+  \div\tenstr = -\grad p + \mu\lapl\vct u,
+\end{equation}
+and so the Cauchy equation \eqref{eq:cauchy_equation} becomes
+\begin{equation}
+  \rho\left(\cd{\vct u}\right) = -\grad p + \mu\lapl\vct u + \rho\vct f.
+  \label{eq:navier-stokes-2}
+\end{equation}
+Equations \eqref{eq:navier-stokes-1} and \eqref{eq:navier-stokes-2} are the
+incompressible Navier-Stokes equations for single-phase flow with constant
+viscosity.
+
+\section{The Navier-Stokes equations for two-phase flow}
+We now consider an immiscible two-phase flow of two Newtonian fluids, each with
+its own viscosity and density.  We let $\Omega_1$ and $\Omega_2$ denote the
+domains occupied by fluid 1 and fluid 2, respectively, and let the interface
+between the fluids be denoted by $\Gamma$.  Then $\Omega
+= \Omega_1\cup\Omega_2$ and $\partial\Omega
+= (\partial\Omega_1\cup\partial\Omega_2)\setminus\Gamma$ are the fluid domain
+and its boundary, respectively.  See \cref{fig:domain} for an illustration of
+a two-phase flow domain.

+  \caption{An illustration of a two-phase flow domain.  The interface $\Gamma$
+    separates the two phases $\Omega_1$ and $\Omega_2$.}
+  \label{fig:domain}
+\end{figure}
+
+The extension of the single-phase model to account for two fluids can be made
+by adding a singular surface-force term to represent the effects of surface
+tension between the fluids.  We assume that the surface tension is constant, in
+which case the singular surface force can be defined as
+\begin{equation}
+  \funssf(\vct x,t)
+  = \int_{\Gamma}\sigma\kappa\vct n\delta(\vct x - \vct x_I(\vct s))\dif\vct s,
+  \label{eq:ssf}
+\end{equation}
+where $\sigma$ is the surface tension, $\kappa$ is the local curvature, $\vct
+n$ is the normal vector, $\delta$ is the Dirac delta function, and $\vct
+x_I(\vct s)$ is a parametrisation of the interface.  Thus the Navier-Stokes
+equations for immiscible and incompressible two-phase flow are
+\begin{align}
+  \label{eq:ns1}
+  \div\vct u &= 0, \\
+  \label{eq:ns2}
+  \rho\left(\cd{\vct u}\right) &= -\grad p + \mu\lapl\vct u
+    + \rho\vct f + \funssf.
+\end{align}
+
+\section{Fluid-fluid interface conditions}
+The surface-tension force and the jump in viscosity and density across the
+interface $\Gamma$ lead to a set of interface conditions that must be satisfied
+along the interface $\Gamma$.  The following is a brief derivation of these
+conditions.
+
+First, we only consider flows where there is no mass transfer, which implies
+that
+\begin{equation}
+  \jmp{\vct u}\cdot\vct n = 0,
+\end{equation}
+where $\jmp{\cdot}$ denotes the jump at the interface, for instance $\jmp{\mu}
+= \mu_2 - \mu_1$.  Further, for viscous flows there is no slip at the
+interface, and thus the tangential velocity component of the two fluids must be
+equal at the interface,
+\begin{equation}
+  \jmp{\vct u}\cdot\vct t = 0.
+\end{equation}
+It follows that
+\begin{align}
+  \label{eq:jmpu}
+  \jmp{\vct u} &= 0, \\
+  \label{eq:jmpJut}
+  \jmp{\grad \vct u}\cdot\vct t &= 0.
+\end{align}
+The latter is a direct consequence of the former.  Both fluids are
+incompressible, which gives the trivial identity $\jmp{\div\vct u} = 0$.  If we
+use the identity
+\begin{equation}
+  \div\vct u
+    = \vct n\cdot\grad\vct u\cdot\vct n + \vct t\cdot\grad\vct u\cdot\vct t
+  \label{eq:divuident}
+\end{equation}
+together with \eqref{eq:jmpJut} we get
+\begin{equation}
+  \vct n\cdot\jmp{\grad\vct u}\cdot\vct n = 0,
+  \label{eq:jmpngradun}
+\end{equation}
+which means that the normal component of the normal derivative of the velocity
+field is continuous across the interface.  Note that in \eqref{eq:divuident}
+and in similar expressions in the following, the nabla operator is only applied
+to $\vct u$, not the normal and tangential vectors that follow.

+      + \intoepdx{ \int_{\Gamma}\sigma\kappa\vct n\delta(\vct x - \vct
+        x_I(\vct s))\dif\vct s}.
+\end{multline}
+Here $\tdi{\vct u} = \partial\vct u/\partial t + \vct u\cdot\grad\vct u$
+denotes the convective derivative.  Now we apply the Gauss theorem and change
+the order of integration in the last term to obtain
+\begin{equation}
+  \intoepdx{\rho\td{\vct u}} = \intdoepds{\tenstr\cdot\vct n}
+    + \intoepdx{\rho\vct f} + \int_\Gamma\sigma\kappa\vct n\dif\vct s.
+\end{equation}
+If we let $\epsilon$ go to zero, the left-hand side and the second term on the
+right-hand side vanish, and we get
+\begin{equation}
+  0 = \int_\Gamma\left( \jmp{\tenstr}\cdot\vct n + \sigma\kappa\vct
+    n \right)\dif s.
+  \label{eq:stressjumpint}
+\end{equation}
+Since the derivation above is also valid for any subset of $\Omega_\epsilon$
+containing a part of $\Gamma$, \eqref{eq:stressjumpint} must hold for any part
+of $\Gamma$.  Therefore
+\begin{equation}
+  0 = \jmp{\vct T}\cdot\vct n + \sigma\kappa\vct n.
+\end{equation}
+With $\vct T = -p\vct I + 2\mu\vct D$ we finally get the interface condition
+for the stresses,
+\begin{equation}
+  \label{eq:stress_jump}
+  \jmp{p}\vct n - \jmp{2\mu\tenD}\cdot\vct n = \sigma\kappa\vct n.
+\end{equation}
+The surface tension force is seen to introduce a discontinuity in the normal
+stresses across the interface.  The tangential stresses are continuous.
+
+\section{Interface conditions for the pressure and the viscous term}
+The previous section gave a brief derivation of the interface conditions for
+immiscible and incompressible two-phase flow without mass transfer.  In order
+to use these conditions for the discretization of the Navier-Stokes equations
+\eqref{eq:ns1} and \eqref{eq:ns2}, we need to rewrite them into a more suitable
+form.  In particular, we want to find explicit expressions for the jump in the
+pressure $\jmp p$ and the viscous term $\jmp{\mu\grad\vct u}$.  The following
+derivation is based on \cite{Hansen05} and \cite{Kang00}.
+
+First, a jump condition for the pressure is obtained by taking the inner
+product of \eqref{eq:stress_jump} with the normal vector $\vct n$,
+\begin{equation}
+  \jmp p = \vct n\cdot\jmp{2\mu\tenD}\cdot\vct n + \sigma\kappa
+      = 2\jmp{\mu}\vct n\cdot \grad\vct u \cdot\vct n
+        + \sigma\kappa,
+  \label{eq:jump_pressure}
+\end{equation}
+where \eqref{eq:jmpngradun} was used for the second equality.
+
+To find the jump in the viscous term, it is first decomposed into an interface
+normal coordinate system as
+\begin{equation}
+  \begin{split}
+    \jmp{\mu\grad\vct u} &=
+  \left(\vct n\cdot\jmp{\mu\grad\vct u}\cdot\vct n\right)\vct n\otimes\vct n +
+  \left(\vct t\cdot\jmp{\mu\grad\vct u}\cdot\vct t\right)\vct t\otimes\vct t
+        \\ &\quad+
+  \left(\vct n\cdot\jmp{\mu\grad\vct u}\cdot\vct t\right)\vct n\otimes\vct t +
+  \left(\vct t\cdot\jmp{\mu\grad\vct u}\cdot\vct n\right)\vct t\otimes\vct n,
+  \end{split}
+\end{equation}
+where $\otimes$ denotes the dyadic product.  We already showed that
+$\jmp{\grad\vct u}\cdot\vct t = 0$ and $\vct n\cdot\jmp{\grad\vct u}\cdot\vct
+n = 0$, cf.\ \eqref{eq:jmpJut} and \eqref{eq:jmpngradun}, which gives
+\begin{align}
+  \vct n\cdot\jmp{\mu\grad\vct u}\cdot\vct n &=
+    \jmp{\mu}\,\vct n\cdot\grad\vct u\cdot\vct n, \\
+  \vct t\cdot\jmp{\mu\grad\vct u}\cdot\vct t &=
+    \jmp{\mu}\,\vct t\cdot\grad\vct u\cdot\vct t, \\
+  \vct n\cdot\jmp{\mu\grad\vct u}\cdot\vct t &=
+    \jmp{\mu}\,\vct n\cdot\grad\vct u\cdot\vct t.
+\end{align}
+We then take the inner product of \eqref{eq:stress_jump} with $\vct t$, which
+gives
+\begin{equation}
+  \vct t\cdot\jmp{\mu\left(\grad\vct u + (\grad\vct u)^T \right)}\cdot\vct n
+  = \vct t\cdot\jmp{\mu\grad\vct u} \cdot\vct n
+    + \jmp{\mu}\vct n\cdot\grad\vct u \cdot\vct t
+  = 0,
+\end{equation}
+or
+\begin{equation}
+  \vct t\cdot\jmp{\mu\grad\vct u}\cdot\vct n =
+    - \jmp{\mu}\vct n\cdot\grad\vct u \cdot\vct t.
+\end{equation}
+The jump in the viscous term becomes
+\begin{multline}
+  \jmp{\mu\grad\vct u} = \jmp{\mu} \Big(
+       (\vct n\cdot\grad\vct u\cdot\vct n)\vct n\otimes\vct n
+     + (\vct n\cdot\grad\vct u\cdot\vct t)\vct n\otimes\vct t \\
+     - (\vct n\cdot\grad\vct u\cdot\vct t)\vct t\otimes\vct n
+     + (\vct t\cdot\grad\vct u\cdot\vct t)\vct t\otimes\vct t \Big).
+\end{multline}
+This can be simplified further by noting that
+\begin{equation}
+  (\grad\vct u\cdot t)\otimes\vct t
+  = (\vct n\cdot\grad\vct u\cdot\vct t)\vct n\otimes\vct t
+    + (\vct t\cdot\grad\vct u\cdot\vct t)\vct t\otimes\vct t.
+\end{equation}
+Thus we obtain the expression for the jump in the viscous term that has been
+used in the present work,
+\begin{multline}
+  \jmp{\mu\grad\vct u} = \jmp{\mu} \Big(
+       (\vct n\cdot\grad\vct u\cdot\vct n)\vct n\otimes\vct n
+     - (\vct n\cdot\grad\vct u\cdot\vct t)\vct t\otimes\vct n \\
+     + (\grad\vct u\cdot\vct t)\otimes\vct t \Big).
+  \label{eq:jumptens}
+\end{multline}
+
+\section{Summary}
+This chapter has given a brief derivation of the immiscible and incompressible
+Navier-Stokes equations for two-phase flow \eqref{eq:ns1} and \eqref{eq:ns2},

+\chapter{Numerical methods}
+\label{chap:numerical-methods}
+This chapter describes the numerical methods that have been used in this thesis
+to solve the Navier-Stokes equations for two-phase flow.  First, a brief
+introduction to the level-set method is given, which is followed by an outline
+of the two projection methods that have been used to solve the Navier-Stokes
+equations.  The spatial and temporal discretization methods are then
+summarized, and at the end of the chapter the new methods to calculate the
+curvature and the normal vectors are presented.
+
+\section{The level-set method}
+\label{sec:level-set}
+In order to solve the Navier-Stokes equations for two-phase flow, we need to
+know the location of the interface.  The level-set method proposed by
+\citet{Osher88} allows us to capture the interface location as the zero level
+set of the level-set function $\varphi(\vct x,t)$.  The level-set function is
+typically defined as a signed-distance function,
+\begin{equation}
+  \varphi(\vct x,t) = \begin{cases}
+     d(\vct x,t) & \text{if } \vct x\in\Omega_2, \\
+    -d(\vct x,t) & \text{if } \vct x\in\Omega_1, \\
+  \end{cases}
+\end{equation}
+where $d(\vct x,t)$ is the shortest distance to the interface $\Gamma$,
+\begin{equation}
+  d(\vct x,t) = \min_{\vct x_I \in \Gamma} |\vct x - \vct x_I|.
+\end{equation}
+Thus the interface can be defined implicitly as
+\begin{equation}
+  \Gamma(t) = \set{\vct x\in\Omega}{\varphi(\vct x,t)=0},
+              \quad t\in \mathbb R^+.
+\end{equation}
+
+The position of the interface is updated by solving an advection equation for
+$\varphi$,
+\begin{equation}
+  \label{eq:ls_adeq}
+  \pdt{\varphi} + \vct{\hat u}\cdot\grad\varphi = 0,
+\end{equation}
+where $\vct{\hat u}$ is the velocity at the interface extended to the entire
+domain.  We extend the interface velocity through solving
+a velocity-extrapolation equation,
+\begin{equation}
+  \label{eq:ls_velextr}
+  \pd{\vct{\hat u}}{\tau} + S(\varphi)\vct n\cdot\grad\vct{\hat u} = 0,
+  \quad \vct{\hat u}_{\tau=0} = \vct u,
+\end{equation}
+to steady state, cf.\ \cite{Adalsteinsson99,Zhao96}.  Here $\tau$ is
+a pseudo-time and $S$ is a smeared sign function which is equal to zero at the
+interface,
+\begin{equation}
+  S(\varphi) = \frac{\varphi}{\sqrt{\varphi^2+2\Delta x^2}}.
+\end{equation}
+
+When we solve the level-set equation \eqref{eq:ls_adeq}, the non-uniform
+advection will distort the signed-distance property of the level-set function,
+and numerical dissipation error adds to this distortion.  The level-set
+function is therefore reinitialized regularly by solving
+\begin{equation}
+  \label{eq:ls_reinit}
+  \begin{split}
+    \pd{\varphi}{\tau} + S(\varphi_0)(|\grad\varphi|-1) &= 0, \\
+    \varphi(\vct x,0) &= \varphi_0(\vct x),
+  \end{split}
+\end{equation}
+to steady state as proposed by \citet{Sussman94}.  The level-set function just
+before initialization is used as the initial condition $\varphi_0$.
+
+The level-set equations \eqref{eq:ls_adeq}, \eqref{eq:ls_velextr}, and
+\eqref{eq:ls_reinit} are discretized in time and space as described in the
+following sections.  The method presented by \citet{Adalsteinsson95} is used to
+improve the computational speed.  The method is often called the narrow-band
+method, since the level-set function is only updated in a narrow band across
+the interface at each time step.
+
+One of the advantages of the level-set method is that normal vectors and
+curvatures can be readily calculated from the level-set function, that is,
+\begin{align}
+  \label{eq:norm}
+  \vct n &= \frac{\grad\varphi}{|\grad\varphi|}, \\
+  \label{eq:curv}
+  \kappa &= \div\left(\frac{\grad\varphi}{|\grad\varphi|}\right).
+\end{align}
+
+\section{Projection methods}
+\label{sec:projection-method}
+We have employed two different projection methods in this thesis to solve the
+incompressible Navier-Stokes equations for two-phase flow \eqref{eq:ns1} and
+\eqref{eq:ns2}.  Papers A, B, and C used the direct projection
+scheme~1~(DP1)~\cite{Hansen05}, and Paper D used the more standard Chorin
+projection method \cite{Chorin68}.
+
+The projection methods are a family of methods for the solution of the
+incompressible Navier-Stokes equations that are based on the Helmholtz-Hodge
+theorem.  This theorem states that an arbitrary vector field can be decomposed
+into a divergence-free part and a rotation-free part.  That is, any vector
+field $\vct a$ can be written as
+\begin{equation}
+  \vct a = \vct a' + \grad\psi,
+\end{equation}
+where $\vct a'$ is a vector with $\div\vct a' = 0$ and $\psi$ is a scalar
+potential.  The proof of this theorem can be found in for instance
+\cite[§3.44]{Aris89} or \cite{Chorin00}.
+
+\subsection{The direct projection scheme 1}
+The DP1 was developed by \citet{Hansen05} and is based on a direct application
+of the Helmholtz-Hodge theorem.  We assume that the velocity $\vct u$ is
+sufficiently smooth, and then rewrite \eqref{eq:navier-stokes-2} to get
+\begin{equation}
+  \label{eq:divFreeVel}
+  \pdt{\vct u} = \vct w - \frac{\grad p}{\rho},
+\end{equation}
+where
+\begin{equation}
+  \vct w = - (\vct u\cdot\grad)\vct u + \nu\grad^2\vct u + \vct f.
+  \label{eq:continuousRightHandVector}
+\end{equation}
+The divergence of \eqref{eq:divFreeVel} yields a Poisson equation for the
+pressure,
+\begin{equation}
+  \div\left(\frac{\grad p}{\rho}\right) = \div\vct w.
+  \label{eq:PoissonDP1}
+\end{equation}
+The DP1 scheme follows from a direct numerical discretization of the above
+equations.  First, $\vct w$ is calculated with
+\eqref{eq:continuousRightHandVector}.  Then the pressure is found by solving
+the Poisson equation \eqref{eq:PoissonDP1}.  Finally, an Euler step is used to
+solve \eqref{eq:divFreeVel}, that is,
+\begin{equation}
+  \vct u^{n+1} = \vct u^n + \Delta t\left(\vct w - \frac{\grad p}{\rho}\right).
+  \label{eq:dp1-update}
+\end{equation}
+
+\subsection{The Chorin projection method}
+The Chorin projection method was presented by \citet{Chorin68}, and is today
+one of the standard methods for solving the Navier-Stokes equations, e.g.\
+\cite{Walker12}.  The method is briefly presented in the following.
+
+Let $\Delta t$ be the time step, and consider the discretization of the
+momentum equation \eqref{eq:navier-stokes-2} with the forward Euler method,
+\begin{equation}
+  \frac{\vct u^{n+1} - \vct u^n}{\Delta t}
+  = -\vct u^n\cdot\grad\vct u^n
+    - \frac{\grad p^{n+1}}{\rho} + \frac\mu\rho\lapl\vct u^n + \vct f,
+  \label{eq:discmomeq}
+\end{equation}
+where $\vct u^n\equiv\vct u(\vct x,n\Delta t)$ and $p^n\equiv p(\vct x,n\Delta
+t)$ are assumed known at time level $n$.  Note that the pressure gradient is
+evaluated at time level $n+1$.  Next, to solve \eqref{eq:discmomeq} in two
+steps, we introduce the intermediate velocity field $\vct u^\star$,
+\begin{equation}
+  \frac{\vct u^{n+1} - \vct u^\star + \vct u^\star - \vct u^n}{\Delta t}
+  = -\vct u^n\cdot\grad\vct u^n
+    - \frac{\grad p^{n+1}}{\rho} + \frac\mu\rho\lapl\vct u^n + \vct f,
+\end{equation}
+which is chosen such that
+\begin{align}
+  \label{eq:ustar}
+  \frac{\vct u^\star - \vct u^n}{\Delta t}
+    &= -\vct u^n\cdot\grad\vct u^n + \frac\mu\rho\lapl\vct u^n + \vct f, \\
+  \label{eq:unext}
+  \frac{\vct u^{n+1} - \vct u^\star}{\Delta t} &= - \frac{\grad p^{n+1}}{\rho}.
+\end{align}
+From \eqref{eq:ustar} we get an explicit expression for $\vct u^\star$,
+\begin{equation}
+  \vct u^{\star} = \vct u^n
+    + \Delta t\left(-\vct u^n\cdot\grad\vct u^n
+        + \frac\mu\rho\,\lapl\vct u^n + \vct f\right).
+\end{equation}
+Next, the divergence of \eqref{eq:unext} and $\div\vct u^{n+1} = 0$ yields
+a Poisson equation for the pressure,
+\begin{equation}
+  \div\left(\frac{\grad p^{n+1}}{\rho}\right)
+    = \frac{\div\vct u^\star}{\Delta t}.
+  \label{eq:PoissonChorin}
+\end{equation}
+Finally, we obtain for \eqref{eq:unext}
+\begin{equation}
+  \vct u^{n+1} = \vct u^\star - \Delta t\frac{\grad p^{n+1}}{\rho}.
+  \label{eq:velcorrection}
+\end{equation}
+
+\section{Spatial discretization}
+\label{sec:x-discr}
+The governing equations \eqref{eq:ns1}, \eqref{eq:ns2}, \eqref{eq:ls_adeq},
+\eqref{eq:ls_velextr}, and \eqref{eq:ls_reinit} are discretized on a staggered
+grid~\cite{Harlow65}, where the scalar values are located at the cell centres
+and the vector values are located at the cell edges, see
+\cref{fig:staggered-grid}.  The domain boundary coincides with cell edges, and
+the fixed grid spacing is $\Delta x$ in the $x$ direction and $\Delta y$ in the
+$y$ direction.

+\end{figure}
+
+The $x$- and $y$-derivatives, divergence, and Laplacian operators are

+\begin{align}
+  \left. G_x p \right|_{i+\frac 1 2,j}
+    &= \frac{p_{i+1,j} - p_{i,j}}{\Delta x}, \\
+  \left. G_y p \right|_{i,j+\frac 1 2}

+       + \frac{p_{i,j+1} - 2p_{i,j} + p_{i,j-1}}{(\Delta y)^2},
+\end{align}
+respectively.  Here $\vct u = (u,v)$ is a vector and $p$ is a scalar.  Note
+that the gradient of a scalar is a vector and has values located at the cell
+edges.  These definitions are consistent with the staggered grid, since the
+gradient returns a vector with components defined on the cell faces, while the
+divergence and the Laplacian returns a scalar defined at the cell centres.
+
+\subsection{Advective terms}
+The advective terms, $\vct u\cdot\grad\vct u$ in the momentum equation
+\eqref{eq:ns2} and $\vct{\hat u}\cdot\grad\varphi$ in the level-set equation
+\eqref{eq:ls_adeq}, and the normal derivative $\vct n\cdot\grad\vct{\hat u}$ in
+the velocity-extrapolation equation \eqref{eq:ls_velextr} are discretized with
+the weighted essentially non-oscillatory (WENO) scheme, cf.~\cite{Fedkiw99}
+and~\cite{Jiang96}.  The WENO scheme is a high-order upwind scheme that is
+fifth-order accurate in smooth regions.  In nonsmooth regions the accuracy is
+reduced to a minimum of third order.  The following is a brief outline of the
+WENO scheme.
+
+First, when we calculate the advective term for the velocity, the vector
+components are required on all cell edges.  That is, we must interpolate the
+$x$-component of the velocity to the location of the $y$-component of the
+velocity and vice versa.  To do this we use a linear interpolation,
+\begin{align}
+  u_{i,j+\frac 1 2} &= \frac 1 4\left(
+      u_{i-\frac 1 2,j  } + u_{i-\frac 1 2,j+1}
+    + u_{i+\frac 1 2,j+1} + u_{i+\frac 1 2,j  } \right), \\
+  v_{i+\frac 1 2,j} &= \frac 1 4\left(
+      v_{i,  j-\frac 1 2} + v_{i+1,j-\frac 1 2}
+    + v_{i+1,j+\frac 1 2} + v_{i  ,j+\frac 1 2} \right).
+\end{align}
+
+Similarly, when we calculate the advective term for the level-set function
+$\varphi$, we first interpolate the velocity to the scalar grid,
+\begin{align}
+  u_{i,j} &= \frac 1 2\left( u_{i+\frac 1 2,j} + u_{i-\frac 1 2,j} \right), \\
+  v_{i,j} &= \frac 1 2\left( v_{i,j+\frac 1 2} + v_{i,j-\frac 1 2} \right).
+\end{align}
+
+We now consider the WENO scheme for the advective operator in 1D at the point
+$x_{i+\frac 1 2}$.  The scheme extends naturally to higher dimensions.  First,
+if $u_{i+\frac 1 2} = 0$, then
+\begin{equation}
+  \left. u\pd u x \right|_{i+\frac 1 2} = 0.
+\end{equation}
+Otherwise we need to calculate a set of five differences that depend on the
+upwind direction.  The differences are denoted $\Delta v_k$ for $k=1,\dots,5$.
+If $u_{i+\frac 1 2}>0$, then we calculate
+\begin{equation}
+  \Delta v_k = \frac{u_{i+\frac{2k-5} 2} - u_{i+\frac{2k-7} 2}}{\Delta x}.
+\end{equation}
+Otherwise if $u_{i+\frac 1 2}<0$, we calculate
+\begin{equation}
+  \Delta v_k = \frac{u_{i-\frac{2k-9} 2} - u_{i-\frac{2k-7} 2}}{\Delta x}.
+\end{equation}
+Next we calculate expressions for the smoothness of three substencils,
+\begin{align}
+  S_1 &= \frac{13}{12}(\Delta v_1 - 2\Delta v_2 + \Delta v_3)^2
+    + \frac 1 4 (\Delta v_1 - 4\Delta v_2 + 3\Delta v_3)^2, \\
+  S_2 &= \frac{13}{12}(\Delta v_2 - 2\Delta v_3 + \Delta v_4)^2
+    + \frac 1 4 (\Delta v_2 - \Delta v_4)^2, \\
+  S_3 &= \frac{13}{12}(\Delta v_3 - 2\Delta v_4 + \Delta v_5)^2
+    + \frac 1 4 (3\Delta v_3 - 4\Delta v_4 + \Delta v_5)^2,
+\end{align}
+where a small $S$ indicates a smooth substencil.  These smoothness factors are
+then used to compute weights for the substencils,
+\begin{equation}
+  w_k = \frac{b_k}{b_1+b_2+b_3},
+\end{equation}
+for $k = 1,2,3$, where
+\begin{equation}
+  b_1 = \frac 1 {10}\frac 1 {(\epsilon+S_1)^2},\quad
+  b_2 = \frac 6 {10}\frac 1 {(\epsilon+S_2)^2},\quad
+  b_3 = \frac 3 {10}\frac 1 {(\epsilon+S_3)^2}.
+\end{equation}
+Here $\epsilon$ is a regularization parameter that is used to avoid division by
+zero.  We have used $\epsilon = 10^{-6}$ in this work.  Finally, the WENO
+scheme for the gradient becomes
+\begin{multline}
+  \left. \pd u x \right|_{i+\frac 1 2} \simeq
+      w_1\left(\frac 1 3\Delta v_1 - \frac 7 6\Delta v_2
+        + \frac{11} 6 \Delta v_3\right) \\
+    + w_2\left(-\frac 1 6\Delta v_2 + \frac 5 6\Delta v_3
+        + \frac 1 3 \Delta v_4\right) \\
+    + w_3\left(\frac1 3\Delta v_3 + \frac 5 6\Delta v_4
+        - \frac 1 6 \Delta v_5\right).
+\end{multline}
+
+\subsection{The viscous term}
+The viscous term $\mu\lapl\vct u$ in the Navier-Stokes equations is discretized
+by standard second-order central differences using the ghost-fluid method
+(GFM)~\cite{Fedkiw99,Kang00,Liu00}.  This method includes the jump in the
+viscous term at the interface \eqref{eq:jumptens} in the discretization stencil
+in a sharp manner.
+
+In the following we present the GFM scheme in the one-dimensional case.  The
+extension to higher dimensions is straightforward.  In order to simplify the
+notation, we omit the half indices and let $k\equiv i+\frac 1 2$.  Further, we
+consider a general case where
+\begin{equation}
+  \jmp u = a_\Gamma, \qquad \jmp{\mu\pd u x} = b_\Gamma.
+\end{equation}
+For the viscous term, $a_\Gamma = 0$, cf.\ \eqref{eq:jmpu}, and $b_\Gamma$ is
+given by the jump tensor~\eqref{eq:jumptens}.  The jump tensor is calculated at
+the cell centres near the interface with the second-order central-difference
+scheme.  It is then interpolated linearly to the cell edges, from where it is
+again interpolated linearly to the interface when needed.
+
+If the interface does not cross the stencil, then the GFM scheme reduces to the
+standard second-order central-difference stencil.  Else there are four
+stencils, depending on the location of the interface.  One such interface
+configuration is sketched in \cref{fig:gfm-scheme-example}.  In all the
+stencils, $\theta$ is defined as the relative distance from the interface to
+the node on the left, for instance
+\begin{equation}
+  \theta = \frac{|\varphi_{k}|}{|\varphi_{k}| + |\varphi_{k+1}|},
+\end{equation}
+where $\varphi_k$ and $\varphi_{k+1}$ are the level-set function values
+linearly interpolated to the vector grid.  The four stencils are given below,
+where $h\equiv\Delta x$.
+\begin{enumerate}
+  \item Phase 1 is to the left and interface lies between $k$ and $k+1$:
+    \begin{align}
+      \begin{split}
+        \left.\pd{} x\left(\mu\pd u x\right)\right|_{x_k}
+          &= \frac{\hat\mu\left(u_{k+1} - u_{k}\right)
+                 - \mu_1\left(u_{k} - u_{k-1}\right)}{h^2} \\
+          &\qquad
+             - \frac{\hat\mu a_\Gamma}{h^2}

+            + \frac{\hat\mu a_\Gamma}{h^2}
+            + \frac{\hat\mu b_\Gamma (1-\theta)}{\mu_1 h},
+      \end{split} \\
+      \hat\mu &= \frac{\mu_1\mu_2}{\theta\mu_1 + (1-\theta)\mu_2}.
+    \end{align}
+  \item Phase 2 is to the left and interface lies between $k-1$ and $k$:

+\subsection{Pressure Poisson equation}
+\label{sec:pressure-poisson}
+The Laplace operator in the Poisson equations \eqref{eq:PoissonDP1} and
+\eqref{eq:PoissonChorin} is also discretized by standard second-order central
+differences using the GFM~\cite{Kang00,Liu00}.  The GFM was discussed in the
+previous section, where stencils were given for the viscous term in the
+one-dimensional case.  For the pressure, the stencils are the same except we
+use $p$ instead of $u$, and $1/\rho$ and $1/\hat\rho$ instead of $\mu$ and
+$\hat\mu$.  To find the jump in the pressure at the interface, $\jmp
+p = a_\Gamma$, the jump condition \eqref{eq:jump_pressure} is calculated at the
+cell centres and then interpolated to the interface.  In addition, we use that
+$b_\Gamma = 0$, which is justified by \citet[Section~3.7]{Kang00}.
+
+The resulting linear system for the pressure is solved with a solver from the
+Portable, Extensible Toolkit for Scientific Computation (PETSc)~\cite{PETSc}.
+PETSc makes available a large selection of solvers.  In most cases, we used the
+direct solver based on LU factorisation or the conjugate gradient method with
+incomplete Cholesky factorisation.  In some cases, we used the GMRES solver
+with a preconditioner, either incomplete LU factorisation or an algebraic
+multigrid method.  See \cite{PETSc} for more details and a list of available
+methods, and see for example~\cite{Iserles09} or~\cite{Saad03} for an
+introduction to linear solvers.
+
+Finally, the gradient of the pressure, used in \eqref{eq:divFreeVel} and
+\eqref{eq:velcorrection}, is also calculated with the GFM.  In one dimension,
+the stencil is
+\begin{align}
+  \left. \frac 1 \rho \pd p x\right|_{i+\frac 1 2}
+           &= \frac 1 {\hat\rho} \frac{(p_{i+1} - a_\Gamma) - p_i} h, \\
+  \hat\rho &= \theta\rho_1 + (1-\theta)\rho_2,
+\end{align}
+if $\phi_i\leq 0$ and $\phi_{i+1}>0$, or else
+\begin{align}
+  \left. \frac 1 \rho \pd p x\right|_{i+\frac 1 2}
+           &= \frac 1 {\hat\rho} \frac{(p_{i+1} + a_\Gamma) - p_i} h, \\
+  \hat\rho &= \theta\rho_2 + (1-\theta)\rho_1,
+\end{align}
+where
+\begin{equation}
+  \theta = \frac{|\varphi_{i}|}{|\varphi_{i}| + |\varphi_{i+1}|}.
+\end{equation}
+
+\section{Temporal discretization}
+\label{sec:t-discr}
+The temporal discretization is done with the explicit strong
+stability-preserving Runge-Kutta (SSP-RK) schemes, see
+\cite{Ketcheson05,Shu88}.  The idea behind the SSP-RK schemes is to preserve
+the stability of a low-order method when it is extended to higher order.  It is
+argued in \cite{Gottlieb01} that if one extends the forward Euler method, which
+is total variation diminishing (TVD) for a suitable discretization of a scalar
+conservation law, to a non-SSP higher-order method, then overshoots may occur
+at discontinuities.
+
+An SSP-RK method can be written as a convex sum of explicit Euler steps with
+time step $\Delta t$,
+\begin{equation}
+  \mathcal E\left(x^n\right) = x^n + \Delta t \mathcal F(x^n,t^n).
+\end{equation}
+where $\mathcal F$ is the residual of the PDE to be solved.  In this thesis we
+have used two methods:  The third-order three-stage SSP-RK method~\cite{Shu88},
+\begin{equation}
+  \begin{split}
+    x^{(1)} &= \mathcal E\left(x^n\right), \\
+    x^{(2)} &= \frac 3 4 x^n + \frac 1 4\mathcal E\left(x^{(1)}\right), \\
+    x^{n+1} &= \frac 1 3 x^n + \frac 2 3\mathcal E\left(x^{(2)}\right),
+  \end{split}
+  \label{eq:ssprk33}
+\end{equation}
+and the third-order four-stage SSP-RK method~\cite{Kraaijevanger91},
+\begin{equation}
+  \begin{split}
+    x^{(1)} &= \frac 1 2 x^n + \frac 1 2\mathcal E\left(x^n\right), \\
+    x^{(2)} &= \frac 1 2 x^{(1)} + \frac 1 2\mathcal E\left(x^{(1)}\right), \\
+    x^{(3)} &= \frac 2 3 x^n + \frac 1 6 x^{(2)}
+               + \frac 1 6\mathcal E\left(x^{(2)}\right), \\
+    x^{n+1} &= \frac 1 2 x^{(3)} + \frac 1 2\mathcal E\left(x^{(3)}\right).
+  \end{split}
+  \label{eq:ssprk34}
+\end{equation}
+
+The semi-discretized velocity-extrapolation equation \eqref{eq:ls_velextr} and
+level-set reinitialization equation \eqref{eq:ls_reinit} can be written as
+systems of ordinary differential equations (ODEs) of the form
+\begin{equation}
+  \od{\vct \psi} \tau = \vct F(\vct\psi,\tau),
+\end{equation}
+where $\vct\psi$ is a vector containing the discrete variables and $\vct F$
+contains the spatially discretized terms.  The explicit Euler step becomes
+\begin{equation}
+  \mathcal E(\vct\psi^n) = \vct\psi^n + \Delta\tau \vct F(\vct\psi^n,\tau^n).
+\end{equation}
+In this thesis, these equations are solved with the third-order four-stage
+SSP-RK method \eqref{eq:ssprk34}.  The four-stage method is used because it is
+more accurate than the three-stage method.  We wanted to make sure that the
+error is mainly dominated by the spatial discretization.
+
+The semi-discretized Navier-Stokes equations \eqref{eq:navier-stokes-1} and
+\eqref{eq:navier-stokes-2} are solved together with the level-set advection
+equation \eqref{eq:ls_adeq} with the third-order three-stage SSP-RK method
+\eqref{eq:ssprk33}.  Here an explicit Euler step $\mathcal E(\vct
+u^n,\varphi^n)$ consists of the following steps:
+\begin{enumerate}
+  \item Calculate the curvature and the normal vectors from $\varphi^n$ with
+    one of the methods described in \cref{sec:curvature}.
+  \item Calculate the intermediate velocity field, either $\vct w$
+    \eqref{eq:continuousRightHandVector} or $\vct u^\star$ \eqref{eq:ustar}.
+  \item Solve the Poisson equation \eqref{eq:PoissonDP1} or
+    \eqref{eq:PoissonChorin} for the pressure as described in
+    \cref{sec:pressure-poisson}.
+  \item Correct the velocity field with either \eqref{eq:dp1-update} or
+    \eqref{eq:velcorrection}.
+  \item Advect the level-set function $\varphi^n$ with \eqref{eq:ls_adeq}.
+\end{enumerate}
+
+\section{Time step restriction}
+\label{sec:deltaT}
+We employ the Courant-Friedrich-Lewy~(CFL) condition to allow adaptive time
+stepping and to enforce stability.  The CFL condition that is used in this
+thesis is
+\begin{equation}
+  \Delta t = \frac{C}{\frac{C_c + C_v} 2
+             + \sqrt{(C_c + C_v)^2 + 4C_g^2 + 4C_s^2}},
+\end{equation}
+where the CFL restriction $C<1$, and $C_c$, $C_v$, $C_s$, and $C_g$ represent
+the contributions from the convective term, the viscous stresses, the surface
+tension, and the gravity, respectively,
+\begin{align}
+  C_c &=  \frac{\max_{i,j}|u_{i,j}|}{\Delta x}
+        + \frac{\max_{i,j}|v_{i,j}|}{\Delta y}, \\
+  C_v &= 2\max\left(\frac{\mu_1}{\rho_1},\frac{\mu_2}{\rho_2}\right)
+         \left(\frac{1}{\Delta x^2} + \frac{1}{\Delta y^2}\right), \\
+  C_s &= \sqrt{\frac{\sigma\max_{i,j}|\kappa_{i,j}|}
+                    {\max(\rho_1,\rho_2)\min(\Delta x^2,\Delta y^2)}}, \\
+  C_g &= \sqrt{\frac{|g_x|}{\Delta x} + \frac{|g_y|}{\Delta y}}.
+\end{align}
+This CFL condition is discussed in more detail by~\citet{Lervag08}, and it is
+based on the condition by \citet{Kang00}.
+
+\section{Axisymmetry}
+For axisymmetric flow, the governing equations \eqref{eq:ns1} and
+\eqref{eq:ns2} become
+\begin{equation}
+  \frac 1 r \pd{} r\left(r u\right) + \pd v z = 0,
+\end{equation}
+\begin{multline}
+  \rho\left(\pdt u + u\pd u r + v\pd u z\right) = -\pd p r \\
+    + \mu\left(\frac 1 r \pd{} r\left(r \pd u r\right)
+          + \pdd u z - \frac u {r^2}\right) + \rho f_r + {f_s}_r,
+\end{multline}
+and
+\begin{multline}
+  \rho\left(\pdt v + u\pd v r + v\pd v z\right) = -\pd p z \\
+    + \mu\left(\frac 1 r \pd{} r\left(r \pd v r\right)
+      + \pdd v z\right) + \rho f_z + {f_s}_z.
+\end{multline}
+Here $u$ and $v$ are the radial and axial velocity components, $f_r$ and $f_z$
+are the radial and axial body-force components, and ${f_s}_r$ and ${f_s}_z$ are
+the radial and axial components of the singular surface force, respectively.
+The equations are solved as explained in the previous sections.
+
+\section{Discretization of the curvature and the normal vector}
+\label{sec:curvature}
+As stated in \cref{sec:level-set}, the normal vector \eqref{eq:norm} and the
+curvature \eqref{eq:curv} can be calculated from the level-set function as
+\begin{align*}
+  \vct n &= \frac{\grad\varphi}{|\grad\varphi|}, \\
+  \kappa &= \div\left(\frac{\grad\varphi}{|\grad\varphi|}\right).
+\end{align*}
+They are typically discretized with the standard second-order
+central-difference scheme, cf.\ \cite{Kang00,Sethian03,Xu06}.  The normal
+vector is calculated at the cell edges, and the curvature is calculated at the
+grid nodes.  The curvature is then interpolated to the interface where needed
+with linear interpolation, for instance with
+\begin{equation}
+  \kappa_\Gamma = \frac{|\varphi_{i,j}|\kappa_{i+1,j}
+  + |\varphi_{i+1,k}|\kappa_{i,j}}{|\varphi_{i,j}| + |\varphi_{i+1,j}|}.
+  \label{eq:curvature-gamma}
+\end{equation}
+
+If the level-set method is used to capture non-trivial geometries, then it will
+contain kink regions, that is, areas where the gradient of the level-set
+function is discontinuous.  \Cref{fig:level-set-function} shows a simple
+example of such a kink region for a level-set function in a one-dimensional
+domain that captures two interfaces, one on each side of $x_i$.  The kink at
+$x_i$ may lead to large errors both for the curvature and the normal vector if
+one is not careful.  Errors in the curvature lead to errors in the surface
+tension force and in the pressure, which in turn lead to errors in the
+interface evolution and in the two-phase flow.  Errors in the normal vector
+affect both the calculation of the viscous jump condition and the advection of
+the interface.  If the level-set method is used to study for example
+coalescence and breakup of drops, these errors may severely affect the
+simulations.

+\end{figure}
+
+This problem was to our knowledge first described by \citet{Smereka03}, who
+increase the numerical smoothing in the curvature discretization to lessen the
+effect.  Several non-smearing approaches have subsequently been developed.
+\citet{Macklin05} used the level-set method to study tumor growth, and they
+present a one-sided direction-difference scheme for the discretization of the
+normal vector and the curvature.  Later, \citet{Macklin06} presented an
+improved geometry-aware curvature discretization, where the curvature is
+calculated based on a local least-squares parametrisation of the interface.
+
+A different approach to avoid the kinks was presented by \citet{Salac08}.  They
+used a level-set extraction technique, where an extraction algorithm was used
+to reconstruct separate level-set functions for each distinct \emph{body}.  The
+term \emph{body} is used here to denote a subset of a given phase or fluid.
+For example, in the case of two drops of water colliding in air, the water
+drops would make two distinct bodies.  One can also avoid the extraction
+algorithm altogether by use of multiple marker functions for different bodies,
+see for instance \cite{Coyajee09,Kwakkel12}.  Note, however, that the latter
+approach means that the different bodies will not coalesce unless explicit
+action is made, cf.~\cite{Kwakkel13}.  Also, both of the approaches mentioned
+here fails to handle the problem of kinks from a single body.  That is, there
+may still be kink areas due to deformed bodies, for instance bodies with thin
+filaments or tails, or bodies shaped like horse shoes.
+
+In the following, we first present the direction-difference
+scheme~\cite{Macklin05}.  We then describe the curve-fitting discretization
+method and the local level-set extraction method.
+
+\subsection{Direction-difference scheme}
+\label{sec:dds}
+The direction-difference scheme (DDS) was introduced by \citet{Macklin05}.  It
+uses a quality function to ensure that the difference stencils never cross any
+kink regions.  The DDS is used in Papers A--C to calculate the normal vectors.
+However, in Paper C it is shown that the DDS does not always yield an accurate
+approximation of the normal vector.
+
+The basic strategy is to use a combination of central differences and one-sided
+differences based on the values of a quality function,
+\begin{equation}
+  Q(\vct x) = \left| 1 - |\grad\varphi(\vct x)|\right|.
+  \label{eq:quality}
+\end{equation}
+The quality function is approximated with central differences, and is used to
+detect the areas where the level-set function differs from the signed-distance
+function.  In the following, let $Q_{i,j} \equiv Q(\vct x_{i,j})$ and define
+a parameter $\eta>0$.  This threshold parameter is tuned such that the quality
+function will detect all the kinks.
+
+The quality function is used to define a direction function,
+\begin{equation}
+  \vct D(\vct x_{i,j}) = (D_x(\vct x_{i,j}), D_y(\vct x_{i,j})),
+\end{equation}
+where
+\begin{equation}
+  D_x(\vct x_{i,j}) = \begin{cases}
+    -1 & \text{if $Q_{i-1,j}<\eta$ and $Q_{i+1,j}\geq\eta$,} \\
+     1 & \text{if $Q_{i-1,j}\geq\eta$ and $Q_{i+1,j}<\eta$,} \\
+     0 & \text{if $Q_{i-1,j}<\eta$ and $Q_{i,j}<\eta$ and $Q_{i+1,j}<\eta$,} \\
+     0 & \text{if $Q_{i-1,j}\geq\eta$ and $Q_{i,j}\geq\eta$ and
+         $Q_{i+1,j}\geq\eta$,} \\
+     4 & \text{otherwise.}
+  \end{cases}
+  \label{eq:dirfunc}
+\end{equation}
+$D_y(\vct x_{i,j})$ is defined in a similar manner.  If $D_x(\vct x_{i,j})
++ D_y(\vct x_{i,j}) > 2$, then $\vct D(\vct x_{i,j})$ is chosen as the vector
+normal to $\grad\varphi(\vct x_{i,j})$.  It is normalized, and the sign is
+chosen such that it points in the direction of the best quality.  See
+\cite{Macklin05} for more details.
+
+The DDS is then defined as
+\begin{equation}
+  \partial_x f_{i,j} = \begin{cases}
+    \frac{f_{i,j} - f_{i-1,j}}{\Delta x}    & \text{if $D_x(x_i,y_j) = -1$,} \\
+    \frac{f_{i+1,j} - f_{i,j}}{\Delta x}    & \text{if $D_x(x_i,y_j) =  1$,} \\
+    \frac{f_{i+1,j} - f_{i-1,j}}{2\Delta x} & \text{if $D_x(x_i,y_j) =  0$,}
+  \end{cases}
+  \label{eq:Ddifference}
+\end{equation}
+and similarly for $\partial_y f_{i,j}$, where $f_{i,j}$ is a piecewise smooth
+function.  The DDS is equivalent to using central differences in smooth areas
+and one-sided differences in areas close to the kinks.
+
+\subsection{Curve-fitting discretization method}
+\label{sec:curvature-curve-fitting}
+The curve-fitting discretization method (CFDM) was first presented
+in~\cite{Lervag11} and is based on the method by \citet{Macklin06}.  The main
+idea is to identify kink regions with the quality function \eqref{eq:quality},
+and to use a curve parametrisation of the closest interface to calculate the
+curvature in regions where the quality function is larger than the threshold
+parameter, $\eta$.
+
+The CFDM applied to the curvature or the normal vector at the grid point $\vct
+x_{i,j}$ can be summarized as follows.  See also \cref{fig:cfdm}, which shows
+an example of the CFDM used at $\vct x_{i,j}$.
+\begin{enumerate}
+  \item If the quality of the level-set function in the neighbourhood of $\vct
+    x_{i,j}$ is good, that is
+    \[
+      Q(\vct{x}_{n,m}) \le \eta \; \forall (n,m) \in [i-1,i+1]\times[j-1,j+1],
+    \]
+    then we use a standard discretization.  Otherwise continue to the next
+    step.
+  \item Locate the closest interface, $\Gamma$.
+  \item Find a set of points on the located interface, $\vct x_1, \dots, \vct
+    x_n \in \Gamma$.
+  \item Create a parametrisation $\vct \gamma(s)$ of the points $\vct x_1,
+    \dots, \vct x_n$.
+  \item Use the parametrisation $\vct \gamma(s)$ to calculate a local level-set
+    function.
+  \item Use a standard discretization of the local level-set function to
+    calculate the curvature or the normal vector.

+\subsection{Local level-set extraction method}
+\label{sec:lolex}
+The local level-set extraction (LOLEX) method is based on the method presented
+by \citet{Salac08}, here called the SLM.  It was found that the latter method
+was insufficient, because it did not treat all the kink problems.  The LOLEX
+method is therefore a further development of the SLM, in that it handles the
+kink regions in a more general manner.
+
+The LOLEX method applied to the curvature or the normal vector at a grid point
+$\vct x_{i,j}$ is summarized by the following algorithm.  The algorithm is
+presented with 2D notation for clarity, and extends easily to 3D.  See also
+\cref{fig:lolex}, which gives a simple example of the procedure.
+\begin{enumerate}
+  \item If the quality in the neighbourhood of $\vct x_{i,j}$ is good, that is
+    \[
+      Q(\vct{x}_{n,m}) \le \eta \; \forall (n,m) \in [i-1,i+1]\times[j-1,j+1],
+    \]
+    then we use a standard discretization.  Otherwise continue to the next
+    step.
+  \item Copy a small, local square centred around $\vct x_{i,j}$ from the
+    level-set function $\varphi$ into a local array $\varphi_\text{loc}$.
+  \item Identify and enumerate all the \emph{bodies} in the local array
+    $\varphi_\text{loc}$.  A \emph{body} is here defined as a set of
+    neighbouring points where $\varphi_\text{loc}<0$, see \cref{fig:lolex}.
+    There will be $n\geq 0$ bodies in any given $\varphi_\text{loc}$ array.
+  \item If no body is identified, that is, if $n=0$, then use a standard
+    discretization with the global level-set function $\varphi$.  Otherwise
+    continue to the next step.
+  \item For each body $n$, extract the relevant parts of $\varphi_\text{loc}$
+    into an array $\varphi_\text{loc}^n$.  If necessary, extrapolate values to
+    ghost cells.
+  \item For each body, $n$, reinitialize $\varphi_\text{loc}^n$.
+  \item At this step, all the bodies in the local grid have their own
+    local level-set functions that have been reinitialized to proper
+    signed-distance functions.  Due to the separation of the bodies, there
+    are no longer any kinks.
+  \item Use the standard discretization of the curvature and the normal
+    vector at the local level-set function that represents the body that is
+    closest to $\vct x_{i,j}$.

+\chapter{The diffuse-domain approach}
+\label{chap:diffuse-domain}
+In the previous chapters, we have considered the modelling of two-phase flows,
+and in particular methods for calculating the curvature and normal vector with
+the level-set method in a reliable manner.  In this chapter, we consider
+a different problem of a more general nature:  How to solve partial
+differential equations (PDEs) in complex domains.  In particular, we consider
+an extension of a diffuse-domain method (DDM) by a high-order correction term
+that gives increased accuracy with respect to interface-width refinements.
+
+We begin with a short introduction to the diffuse-domain approach.  We then
+outline how it can be used to derive a DDM for the steady reaction-diffusion
+equation with Neumann boundary conditions.  Next, we continue with a brief
+introduction to the method of matched asymptotic expansions.  Finally, we
+introduce the high-order correction term derived in Paper~E and show that the
+resulting DDM converge with second order in the diffuse-interface width to the
+original problem.  The analysis also shows that the correction term is not
+necessary for second-order convergence.
+
+\section{Introduction}
+There exist several methods for solving PDEs in complex domains.  Most of them
+have in common that they require tools or methods that are not frequently
+available in standard finite-element or finite-difference software packages.
+Examples of such methods include the immersed-interface method
+\cite{LeVeque94}, the matched interface and boundary method \cite{Zhou06}, the
+extended and composite finite-element method \cite{Dolbow09}, embedded boundary
+methods \cite{Johansen98}, cut-cell methods \cite{Ji06}, and ghost-fluid
+methods \cite{Fedkiw99}.  A different approach, known as the fictitious domain
+method~\cite{Glowinski94,Glowinski96} or the domain imbedding
+method~\cite{Buzbee71}, either augments the original system with equations for
+Lagrange multipliers to enforce the boundary conditions, or use the penalty
+method to enforce the boundary conditions weakly.  For a more complete list of
+references, see Paper~E.
+
+The DDM is an alternative method for solving PDEs in complex domains.  The main
+idea is to use an implicit representation of the boundary, where the sharp
+boundary is replaced by a diffuse layer.  The PDEs are then reformulated on
+a larger, regular domain, and the boundary conditions are incorporated via
+source terms in the diffuse layer.  When the thickness of the diffuse layer is
+reduced, these source terms tend towards singular source terms.  The resulting
+PDEs can then be solved with the use of standard tools and methods.
+
+The diffuse-domain approach was first introduced by \citet{Kockelkoren03} to
+study diffusion inside a cell with homogeneous Neumann boundary conditions at
+the cell boundary.  It was later used by \citet{Li09} to develop a DDM for
+solving PDEs in complex evolving domains with Dirichlet, Neumann and Robin
+boundary conditions, which is hereafter called the DDM1.  The DDM1 has been
+used by \citet{Teigen09-b}, who modelled bulk-surface coupling of material
+quantities on a deformable interface.  It was also used by \citet{Aland10} to
+simulate incompressible two-phase flows in complex domains in 2D and 3D, and by
+\citet{Teigen11} to study two-phase flows with soluble surfactants.
+
+An analysis of the error behaviour of the diffuse-domain approach was done by
+\citet{Franz12} for a diffuse-domain approximation of an elliptic problem with
+Dirichlet boundary conditions.  They considered the infinity norm of the
+difference of the approximated solution and the exact solution, and their
+analysis shows that the approximation quality is of order one in the interface
+width.
+
+In Paper~E, we present the DDM2, which is an extension of the DDM1 by
+a high-order correction term.  The DDM2 is derived for elliptic problems with
+Neumann and Robin boundary conditions, and it is shown to be asymptotically
+second-order accurate in the interface width.  However, the analysis in Paper~E
+is somewhat lacking in that it assumes that the DDM1 is only first-order
+accurate.  In the following sections, we extend the analysis of Paper~E and
+show that the DDM1 is also second-order accurate.  The analysis is shown for
+the steady reaction-diffusion equation with Neumann boundary conditions, but
+the same technique also applies for the corresponding Robin problem.
+
+\section{The DDM for a Neumann problem}
+Consider the steady reaction-diffusion equation with Neumann boundary
+conditions,
+\begin{equation}
+  \begin{alignedat}{2}
+    \lapl u - u  &= f        & \txin D, \\
+    \ndot\grad u &= g \qquad & \txon \partial D,
+  \end{alignedat}
+  \label{eq:ddan}
+\end{equation}
+where $f$ and $g$ are given.  Let $\chi_D$ be the characteristic function of
+$D$,
+\begin{equation}
+  \chi_D = \begin{cases}
+    1 & \text{if $x\in D$,} \\
+    0 & \text{if $x\notin D$.}
+  \end{cases}
+\end{equation}
+The main idea with the diffuse-domain approach is to extend the original
+equation \eqref{eq:ddan} into a larger and regular domain $\Omega\supset D$, as
+depicted in \cref{fig:ddadomain}.  The extension can be written as
+\begin{equation}
+  \div(\chi_D\grad u) - \chi_D u + \text{BC} = \chi_D f,
+  \label{eq:ddm}
+\end{equation}
+where BC is a singular source term that represents the physical boundary
+condition on $\partial\Omega$.

+  \end{tikzpicture}
+  \caption{A regular domain $\Omega$ that contains a complex domain $D$.}
+  \label{fig:ddadomain}
+\end{figure}
+
+The characteristic function is typically approximated by the phase-field
+function,
+\begin{equation}
+  \chi_D \simeq \phi(\vct x,t) = \frac{1}{2} \left( 1
+  - \tanh \left( \frac{3r(\vct x,t)}{\epsilon} \right) \right),
+  \label{eq:characteristic}
+\end{equation}
+where $\epsilon$ is the interface width and $r(\vct x,t)$ is the
+signed-distance function with respect to the boundary $\partial D$, which is
+taken to be negative inside $D$.
+
+The main difficulty with the diffuse-domain approach is the derivation of
+approximations for the boundary condition term BC.  \citet{Li09} give four
+approximations that are shown to converge asymptotically with first order in
+$\epsilon$ to the original equation when $\epsilon$ is decreased.  In the
+following we consider the approximation
+\begin{equation}
+  \text{BC} \simeq |\grad\phi| g.
+  \label{eq:bc1}
+\end{equation}
+If we combine the above approximations \eqref{eq:characteristic} and
+\eqref{eq:bc1}, we get a DDM1 equation for \eqref{eq:ddan},
+\begin{equation}
+  \div\left(\phi\grad u\right) - \phi u +  |\grad\phi| g = \phi f.
+  \label{eq:ddm1}
+\end{equation}
+
+\section{The method of matched asymptotic expansions}
+The following is a brief introduction to the method of matched asymptotic
+expansions, which is used to show that a given diffuse-domain approximation
+converges to the original problem when the interface width is decreased.  More
+details can be found in Paper~E and in \cite{Pego88}.
+
+Let $u$ be some diffuse-domain variable.  The asymptotic convergence of a given
+diffuse-domain approximation can be shown through expansions of the
+diffuse-domain variables in powers of the interface thickness $\epsilon$ in
+regions close to and far from the interface.  For example, the expansions of
+$u$ are
+\begin{align}
+  u(\vct x)        &= \sum_{k=0}^\infty \epsilon^k      u^{(k)}(\vct x), \\
+  \hat u(z,\vct s) &= \sum_{k=0}^\infty \epsilon^k \hat u^{(k)}(z,\vct s),
+\end{align}
+where $u(\vct x)$ and $\hat u(\vct s,z)$ denote the outer and inner expansions,
+respectively.  Here $z$ is a stretched variable,
+\begin{equation}
+  z = \frac{r(\vct x)}{\epsilon},
+\end{equation}
+where $r$ is the signed distance from the point $\vct x$ to $\partial D$ and is
+taken to be negative inside $D$.  Further, $z$ and $\vct s$ form a local
+coordinate system such that
+\begin{equation}
+  \vct x(\vct s,z) = \vct X(\vct s) + \epsilon z\vct n(\vct s),
+\end{equation}
+where $\vct X(\vct s)$ is a parametrisation of the interface, $\vct n(\vct s)$
+is the interface normal vector, and $z$ is a stretched variable.
+
+When the inner and outer expansions are found, they are matched in a region
+where both solutions are valid and where $\epsilon z = \bigo 1$, see
+\cref{fig:regions}.  The outer solution is then evaluated in the inner
+coordinates, which leads to a set of matching conditions that must hold when
+$\epsilon\to 0$.  If we consider $\epsilon$ to be fixed and let $z \to
+\pm\infty$, we get the following asymptotic matching conditions:
+\begin{equation}
+  \label{eq:match1}
+  \zlimpm \hat u^{(0)}(z,\vct s) = u^{(0)}(\vct s),
+\end{equation}
+and as $z \to \pm\infty$,
+\begin{align}
+  \label{eq:match2}
+  \hat u^{(1)}(z,\vct s) &= u^{(1)}(\vct s)
+    + z\ndot\grad u^{(0)}(\vct s) + \smallo 1, \\

+      + z\ndot\grad u^{(1)}(\vct s) \\
+      &\quad + \frac{z^2}{2} (\ndot\grad)\grad u^{(0)}(\vct s)\cdot\vct n
+      + \smallo 1.

+
+We remark that the inner expansion is used to obtain the boundary condition on
+$\partial D$, and that the outer solution is used to obtain the sharp-interface
+equation inside the physical domain $D$.
+
+To show that a given DDM approximation converges with second order, one must
+show that the order-one term of the outer solution of the DDM equation is zero
+in $D$.  As an example, we consider the outer solution of the DDM1 equation
+\eqref{eq:ddm1}, which is
+\begin{equation}
+  \begin{split}
+    \lapl u^{(0)} - u^{(0)} &= f, \\
+    \lapl u^{(1)} - u^{(1)} &= 0, \\
+    \lapl u^{(k)} - u^{(k)} &= 0,\qquad k = 2,3,\dots.
+  \end{split}
+  \label{eq:ddm_outer}
+\end{equation}
+For the solution to be asymptotically second order, that is $u = u^{(0)}
++ \bigo{\epsilon^2}$, we must have that $u^{(0)}$ satisfies the original
+problem \eqref{eq:ddan} and that $u^{(1)}=0$.  Thus the inner expansion must
+yield a boundary condition for $u^{(1)}$ to enforce $u^{(1)}=0$.
+
+\section{Asymptotic analysis of the DDM1 and the DDM2}
+\label{sec:DDM2}
+In Paper~E we present the DDM2, which extends the DDM1 \eqref{eq:ddm1} with
+a high-order correction term,
+\begin{equation}
+  \div\left(\phi\grad u\right) - \phi u +  |\grad\phi| g
+    + r|\grad\phi|\left(f - \kappa  g - \lapls u + u\right) = \phi f.
+  \label{eq:ddm2}
+\end{equation}
+Here $r|\grad\phi|\left(f - \kappa  g - \lapls u + u\right)$ is the
+correction term, $\kappa$ is the curvature of the boundary $\partial D$, and
+$\lapls u$ is the surface Laplacian of $u$, which can be defined as
+\begin{equation}
+  \lapls u \equiv
+  \left( I - \vct n\otimes\vct n \right)
+        \div \left( I - \vct n\otimes\vct n \right)\grad u,
+\end{equation}
+where $I$ is the identity matrix and $\vct n$ is the normal vector.  The
+curvature can be calculated from the phase-field function
+\eqref{eq:characteristic} as
+\begin{equation}
+  \kappa = -\div\frac{\grad\phi}{|\grad\phi|}.
+\end{equation}
+
+In the following, we use the method of matched asymptotic expansions to show
+that the DDM1 \eqref{eq:ddm1} and the DDM2 \eqref{eq:ddm2} are both
+second-order approximations of \eqref{eq:ddan} in $\epsilon$.  First, it is
+easy to see that the outer expansions of both approximations are given by
+\eqref{eq:ddm_outer}.
+
+Next, we consider the inner expansion of the DDM2 \eqref{eq:ddm2}, which is
+\begin{multline}
+  \frac{1}{\epsilon^2}\left(\phi\hat u_z\right)_z
+  + \frac \kappa \epsilon \phi\hat u_z
+  + \phi\lapls \hat u
+  - \phi\hat u \\
+  - \frac 1 \epsilon \phi_z g
+  - z\phi_z\left(\hat u + \hat f - \kappa g - \lapls\hat u\right)
+  = \phi \hat f.
+  \label{eq:ddm_inner}
+\end{multline}
+We expand $\hat u(z,\vct s)$ in powers of $\epsilon$ and collect the lowest
+order terms,
+\begin{equation}
+  \left(\phi\hat u_z^{(0)}\right)_z = 0.
+\end{equation}
+If we integrate over all $z$, we get that $\hat u_z^{(0)} = 0$.  The next order
+terms of~\eqref{eq:ddm_inner} then give
+\begin{equation}
+  \left(\phi\hat u_z^{(1)}\right)_z = \phi_z g,
+\end{equation}
+and again we integrate, which gives that
+\begin{equation}
+  \phi\hat u_z^{(1)} = \phi g + C
+  \label{eq:uz1}
+\end{equation}
+where the constant $C$ must be zero, since $\lim_{z\to\infty}\phi(z) = 0$.  Now
+consider the limit $z\to-\infty$ and use the matching condition
+\eqref{eq:match2} to get
+\begin{equation}
+  \ndot\grad u^{(0)} = g.
+\end{equation}
+Thus $u^{(0)}$ satisfies the original problem at least to first order in
+$\epsilon$.  This shows that both DDM1 and DDM2 are first-order approximations
+of the sharp-interface problem.
+
+To obtain the result for the next order, we need to apply the derivative of
+the matching condition \eqref{eq:match3},
+\begin{equation}
+  \hat u_z^{(2)} = \ndot\grad u^{(1)}
+      + z (\ndot\grad)\grad u^{(0)}\cdot\vct n.
+  \label{eq:match3_z}
+\end{equation}
+Further, we use that $u^{(0)}$ satisfies
+\begin{equation}
+  \lapl u^{(0)} - u^{(0)} = f^{(0)},
+\end{equation}
+and that the Laplacian may be decomposed as
+\begin{equation}
+  \lapl u = (\ndot\grad)\grad u\cdot\vct n + \kappa\ndot\grad u + \lapls u,
+\end{equation}
+to get
+\begin{equation}
+  (\ndot\grad)\grad u^{(0)}\cdot\vct n
+    = u^{(0)} + f^{(0)} - \kappa g - \lapls u^{(0)}.
+  \label{eq:ngradun}
+\end{equation}
+Now insert \eqref{eq:ngradun} into \eqref{eq:match3_z} and use the matching
+condition \eqref{eq:match1} to obtain a modified matching condition,
+\begin{equation}
+  \hat u_z^{(2)} - z\left(\hat u^{(0)} + \hat f^{(0)}
+        - \kappa g - \lapls \hat u^{(0)}\right)
+  = \ndot\grad u^{(1)}.
+  \label{eq:match3_z2}
+\end{equation}
+
+We are now ready to consider the zeroth order terms,
+\begin{multline}
+  \label{eq:o1}
+  \left(\phi\hat u^{(2)}_z\right)_z
+  + \phi\kappa\hat u_z^{(1)}
+  + \phi\lapls \hat u^{(0)}
+  - \phi\hat u^{(0)} \\
+  - z\phi_z\left(\hat u^{(0)}
+      + \hat f^{(0)} - \kappa g - \lapls\hat u^{(0)}\right)
+  = \phi \hat f^{(0)}.
+\end{multline}
+The modified matching condition \eqref{eq:match3_z2} motivates that we subtract
+and add the term
+\[
+  \bigg(z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\bigg)_z
+\]
+to \eqref{eq:o1}, which gives
+\begin{multline}
+  \bigg(\phi\hat u_z^{(2)}
+    - z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\bigg)_z \\
+  + \bigg(z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\bigg)_z \\
+  + \phi\kappa\hat u_z^{(1)}
+  + \phi\lapls \hat u^{(0)}
+  - \phi\hat u^{(0)} \\
+  - z\phi_z\left(\hat u^{(0)}
+      + \hat f^{(0)} - \kappa g - \lapls\hat u^{(0)}\right)
+  = \phi \hat f^{(0)}.
+\end{multline}
+We expand the terms and use \eqref{eq:uz1},
+\begin{multline}
+  \bigg(\phi\hat u_z^{(2)}
+    - z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\bigg)_z \\
+  + \cancel{\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)} \\
+  + z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)_z \\
+  + \cancel{\phi\kappa g
+  + \phi\lapls \hat u^{(0)}
+  - \phi\hat u^{(0)}}
+  = \cancel{\phi \hat f^{(0)}},
+  \label{eq:o2}
+\end{multline}
+or
+\begin{multline}
+  \bigg(\phi\hat u_z^{(2)}
+    - z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\bigg)_z \\
+  + z\phi\left(\cancel{\hat u_z^{(0)}} + \hat f_z^{(0)}
+      - \cancel{(\kappa g)_z}
+      - \cancel{\lapls \hat u_z^{(0)}}\right) = 0.
+\end{multline}
+If we assume that $\hat f_z^{(0)}$, we get
+\begin{equation}
+  \bigg(\phi\hat u_z^{(2)}
+    - z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\bigg)_z = 0.
+  \label{eq:o3}
+\end{equation}
+Finally, we integrate the left-hand side and take the limit,
+\begin{align}
+  \nonumber
+  \eint{\bigg(\phi\hat u_z^{(2)}
+    &- z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+     - \lapls \hat u^{(0)}\right)\bigg)_z} \\
+  \nonumber
+  &= \ejmp{\phi\hat u_z^{(2)}
+    - z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)} \\
+  \nonumber
+  &= -\zlimm{\left(\hat u_z^{(2)}
+    - z\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\right)} \\
+  &= -\ndot\grad u^{(1)},
+\end{align}
+thus
+\begin{equation}
+  \ndot\grad u^{(1)} = 0.
+  \label{eq:ngradu1}
+\end{equation}
+Combined with \eqref{eq:ddm_outer}, this shows that $u^{(1)}=0$, and so DDM2
+converges asymptotically with second order to the original problem.
+
+The analysis above also holds for DDM1, except instead of \eqref{eq:o3} we get
+\begin{multline}
+  \bigg(\phi\hat u_z^{(2)}
+    - z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\bigg)_z \\
+  = - z\phi_z \left(\hat u^{(0)} + \hat
+        f^{(0)} - \kappa g - \lapls \hat u^{(0)}\right)
+  = - z\phi_z D,
+  \label{eq:o4}
+\end{multline}
+where $D$ is independent of $z$.  Now we use that
+\begin{equation}
+  \phi_z = -(3 \sech^2 3z)/2,
+\end{equation}
+which follows from the definition of the phase-field function
+\eqref{eq:characteristic}.  We integrate the right-hand side, which gives
+\begin{equation}
+  D\eint{z\phi_z} = -D\frac 3 2\eint{z\sech^2 3z} = 0.
+\end{equation}
+Thus DDM1 is also second order in $\epsilon$.
+
+The difference between the DDM1 and the DDM2 is therefore that the correction
+term with the DDM2 directly cancels the term on the right-hand side in
+\eqref{eq:o4}.  This should give an increase of accuracy, but the convergence
+order remains the same.
+
+The analysis for the corresponding Robin problem is essentially the same as the
+above.  In Paper~E, the DDM1 and DDM2 are compared for several elliptic
+problems with both Neumann and Robin boundary conditions.  The results of
+Paper~E show that the correction term in the DDM2 leads to an increase of
+accuracy and that both DDM1 and DDM2 converge with second-order accuracy.
+
+\section{Summary}
+In this chapter, we have given a brief introduction to the diffuse-domain
+method (DDM).  We considered a steady reaction-diffusion equation with Neumann
+boundary conditions \eqref{eq:ddan} and two DDM approximations:  DDM1
+\eqref{eq:ddm1} and DDM2 \eqref{eq:ddm2}.  The DDM2 is an extension of DDM1 by
+a high-order correction term, and was first derived in Paper~E.
+
+Next, we gave an outline of the method of matched asymptotic expansions, and we
+used it to show that both the DDM1 and the DDM2 converged asymptotically with
+second order in the diffuse-interface width to the original equation
+\eqref{eq:ddan}.  The analysis shows that the correction term in the DDM2 leads
+to a cancellation in the asymptotic expansions.  By doing the integration, we
+see that this cancellation is not necessary for obtaining the second order
+convergence.

+\section[Paper A]{Paper A:  Calculation of interface curvature with the
+  level-set method}
+Karl Yngve Lervåg.  Published in \emph{MekIT'11 - 6th National Conference on
+  Computational Mechanics, Trondheim}, 2011.  ISBN: 978-82-519-2798-7.
+
+In this paper I address a problem with the calculation of the interface
+curvature with the level-set method, cf.\ \cref{sec:curvature}.  The curvature
+can be calculated from the level-set function, $\phi$, as
+\begin{equation}
+  \kappa = \div\vct n = \div\frac{\grad\phi}{|\grad\phi|}.
+\end{equation}
+It is typically discretized by standard methods such as the second-order
+central-difference scheme (CD-2), and interpolated to the interface where
+needed \cite{Osher88,Kang00,Osher03}.  However, the level-set function as
+a signed-distance function will tend to have kinks where its gradient is
+discontinuous.  The standard methods may lead to large errors in the curvature
+close to these regions, which in turn may lead to errors in the surface tension
+force.
+
+The main contribution of this paper is a new curve-fitting discretization
+method (CFDM) for the curvature (see \cref{sec:curvature-curve-fitting}).  The
+method is based on the approach developed by \citet{Macklin06}.  It differs in
+that it uses a cubic Hermite spline parametrisation of the interface, and that
+the curvature values are calculated on the grid and then interpolated to the
+interface as opposed to using a localised grid centred at the interface as in
+\cite{Macklin06}.

+    discretization leads to large errors in the curvatures in areas that are
+    close to two interfaces.}
+  \label{fig:A1}
+\end{figure}
+
+The CFDM is tested and compared with the CD-2 for two test cases, and it is
+shown to yield better results in both cases.  \Cref{fig:A1} shows one of these
+results, where the calculated curvature values are compared.  In the example,
+a cylindrical drop impacts on a liquid film.  The figure shows that the CD-2
+leads to large errors in the curvature calculations in the kink regions, that
+is, the red and dark blue regions in \cref{fig:A1a} near the liquid film.
+These errors are not present with the new method, cf.\ \cref{fig:A1b}.
+
+\paragraph{My contribution:}  I developed the method and implemented it into

+\cref{sec:deltaT,sec:t-discr,sec:x-discr,sec:projection-method,sec:curvature}.
+I ran the numerical simulations.  I wrote the paper and presented the work at

+\section[Paper B]{Paper B:  Curvature calculations for the level-set method}
+Karl Yngve Lervåg and Åsmund Ervik.  Published in \emph{ENUMATH 2011}
+proceedings volume, Springer, 2013.  ISBN: 978-3642331336.
+
+This paper is a continuation of Paper A.  The main contribution in this paper
+is a comparison of different methods for calculating the curvature in a robust
+manner with the level-set method in the kink regions.  In particular, the
+CFDM\footnote{The method is called LM in the paper.  Here CFDM is used, in
+  order to be consistent with the rest of the thesis.} that was presented in
+Paper A is compared with Macklin and Lowengrub's method (MLM)~\cite{Macklin06}.
+In addition, the method is compared with the second-order central-difference
+scheme (CD-2) and the more recent method presented by \citet{Salac08}, here
+called Salac and Lu's method (SLM).
+
+The main result in the paper is shown in \cref{fig:B1}, which shows
+a comparison of the methods for a case where two drops collide in a 2D shear
+flow.  In particular, it shows snapshots of the evolution of the interfaces and
+the curvature at times $t=\SI{2.30}{s}$, $t=\SI{2.75}{s}$, and
+$t=\SI{3.10}{s}$.  The results show that all of the improved methods, that is
+MLM, CFDM, and SLM, handle the kink region in a more reliable manner than CD-2.
+The reason that the result with MLM differs from those with CFDM and SLM might
+be that it uses a localised grid centred at the interface to calculate the
+curvature, which means that it does not need to use interpolation of the
+curvature from the grid to the interface.  Note that the difference is mainly
+that the MLM results in slightly earlier coalescence in the given case.

+\section[Paper C]{Paper C:  Calculation of the interface curvature and normal
+  vector with the level-set method}
+Karl Yngve Lervåg, Bernhard Müller, and Svend Tollak Munkejord.  Published in
+Computers and Fluids, volume 84 (2013), 218--230.
+
+Paper A presented the curve-fitting discretization method (CFDM) for the
+calculation of the curvature with the level-set method.  The method was
+designed to be robust in the calculation of the curvature in kink regions, that
+is regions where the gradient of the level-set function is not smooth.  This
+paper presents the details of the CFDM and applies it to the calculation of
+both the curvature and the normal vector.
+
+In the paper we compare the CFDM with the second-order central-difference
+scheme (CD-2) for several test cases.  In the first case, we consider the
+curvature calculations for a nontrivial geometry that includes some kink
+regions.  This is a static test case with no flow, and the results show that
+the CD-2 leads to large errors for the curvature calculations in areas close to
+kink regions and that these errors are not present with the CFDM.
+
+In the following two cases, we consider the collision of two drops in a 2D
+shear flow and in an axisymmetric flow.  These cases show that the errors in
+the curvature calculations in the kink regions with the CD-2 lead to errors in
+the pressure that prevents coalescence.  These errors are prevented with the
+CFDM.  The curvature and the evolution of the interfaces for the axisymmetric
+case are shown in \cref{fig:C1,fig:C2}.  As in the earlier results of Papers
+A and B, the figures show that the errors in the curvature calculation with
+CD-2 prevent coalescence, in this case leading to a slower coalescence process.

+\section[Paper D]{Paper D:  A robust method for calculating interface curvature
+  and normal vectors using an extracted local level set}
+Åsmund Ervik, Karl Yngve Lervåg, and Svend Tollak Munkejord.  Submitted to
+Journal of Computational Physics, 2013.
+
+In this paper we present an alternative method for the calculation of the
+curvature and the normal vector of an interface with the level-set method in
+kink regions, hereafter called the local level-set extraction (LOLEX) method.
+The method is based on a method presented by \citet{Salac08} (SLM), who handle
+the kink region by extracting different bodies of a domain into separate
+level-set functions.  This procedure removes most of the kink regions, but it
+does not handle kink regions that are due to complex interfaces of single
+bodies.  Our method extends the SLM by making it local.  That is, we only
+consider the local area around the point for which we are calculating the
+curvature or the normal vector.  This leads to a method that is more generally
+applicable, as shown in \cref{fig:D1}.  The figure shows a comparison between
+the LOLEX method, the SLM, and the standard central differences (CD-2).  CD-2
+leads to curvature spikes at the kink regions, as explained in
+\cref{sec:curvature}.  The SLM gives a better result for the kink regions
+around the rightmost disc.  However, since the other two discs are connected to
+each other and to the film, they are considered to be the same body and are
+extracted into the same level-set function.  Several kink regions are therefore
+not removed.  Since the LOLEX method only considers the local area, as
+explained in \cref{sec:lolex}, it is able to handle all the kink regions in
+a robust manner.

+    negative and red is positive.}
+  \label{fig:D1}
+\end{figure}
+
+The LOLEX method has proven to be a good alternative to the CFDM presented in
+Paper A.  Its main advantages are that it does not rely on complex algorithms
+as used in the CFDM or by \citet{Macklin06}, and that the method easily extends
+to 3D as demonstrated in the paper in Section~4.4.
+
+In the previous papers A--C, we used the DP1 projection method by
+\citet{Hansen05}.  In this paper we instead used the more standard Chorin
+projection method.  These methods differ in that the DP1 assumes
+\begin{equation}
+  \div\left(\pdt{\vct u}\right) = 0.
+\end{equation}
+When compared with the Chorin method, this assumption becomes equivalent to
+assuming that $\div\vct u^{n} = 0$ in \eqref{eq:PoissonChorin}.  That is, the
+DP1 assumes that the initial velocity field is divergence free.  We have found
+that the DP1 works well in most cases, but that it is less robust than the
+Chorin method.  In particular, the Chorin method is not equally affected by
+errors in the curvature calculations in kink regions.  In other words, the
+difference between using a standard discretization and an improved
+discretization of the curvature is smaller with the Chorin method than with the
+DP1.
+
+The LOLEX method is used for several test cases and compared with CD-2.  The
+results indicate that even though we use the Chorin projection method, the
+LOLEX method outperforms CD-2 in all cases.  Further, the results agree well
+with experiments, except for time instants, as shown in \cref{fig:D2}.  The
+exact reason why the time instants do not match is not known, but one reason
+may be that the initial condition of the numerical simulation did not match the
+corresponding state of the experiment.

+    from~\cite{Zhao11}, Copyright (2011), with permission from Elsevier.}
+  \label{fig:D2}
+\end{figure}
+
+When we study the drop-film collision processes, an important consequence of
+the error in the curvature calculation is a loss of kinetic energy.  This can
+be seen in \cref{fig:D3}, which compares the LOLEX method with CD-2 at two
+different stages of the collision process.  The figure also compares two
+different frequencies of reinitialization of the level-set function:  Every
+7 time steps ((a) and (c)) and every single time step ((b) and (d)).  The
+figure shows that the error in the curvature calculation with CD-2 leads to
+a shorter neck, as seen in \cref{fig:D3}, (c) and (d).  The error is larger for
+the higher frequency of reinitialization.  The results indicate that CD-2 leads
+to a loss of kinetic energy during the collision process when compared with the
+LOLEX method.  The LOLEX method is not significantly affected by the amount of
+reinitialization, and the kink region does not affect the curvature
+calculation, cf.\ \cref{sec:lolex}.  Thus the pressure field is more sensible,
+as seen in \cref{fig:D3} (a) and (b).  Finally, we remark that some authors
+have noted \cite{Blanchette06} that the height of the neck and the dynamics of
+the capillary waves are important factors for the partial coalescence
+mechanism, which implies that the correct calculation of the curvature is
+important to capture the correct physical behavior.

+\section[Paper E]{Paper E:  Towards a second-order diffuse-domain approach for
+  solving PDEs in complex geometries}
+Karl Yngve Lervåg and John Lowengrub.  Submitted to Communications in Math.
+Sciences, 2013.
+
+\citet{Li09} developed a diffuse-domain method for solving partial-differential
+equations (PDEs) inside complex, dynamic geometries with Dirichlet, Neumann,
+and Robin boundary conditions.  This method is in the following referred to as
+DDM1.  They use the diffuse-domain approach~\cite{Kockelkoren03}, where the
+geometry is represented implicitly and the sharp boundary is replaced by
+a diffuse layer with a fixed interface width.  The original governing equations
+are then reformulated on a larger, regular domain and the boundary conditions
+are incorporated via singular source terms.  The method of matched asymptotic
+expansions is used to show that the reformulated problem converges
+asymptotically to the original problem.
+
+In the present paper, we use the method of matched asymptotic expansions to
+extend the DDM1 with include a high-order correction term in the diffuse
+formulation, cf.\ \cref{sec:DDM2}.  The extension is derived for elliptic
+problems with Neumann and Robin boundary conditions, where the correction term
+is shown to yield an asymptotically second-order accurate approximation of the
+original problem.  The new method is referred to as the DDM2.
+
+The DDM1 and DDM2 are compared for a selection of test problems.  The resulting
+equations were discretized by standard second-order central-difference schemes
+on uniform grids, and solved by a multigrid method.  A red-black Gauss-Seidel
+type iterative method was used as a smoother, see \cite{Wise07}.
+
+In addition to the comparison of DDM1 and DDM2, we compared two different
+approximations of the boundary conditions.  These correspond to different
+diffuse-interface surface delta functions, and for the Neumann boundary
+conditions they are
+\begin{equation}
+  \text{BC1} = |\grad\phi| g,
+\end{equation}
+and
+\begin{equation}
+  \text{BC2} = \epsilon|\grad\phi|^2 g.
+\end{equation}
+The approximations are similar for the Robin boundary condition, although here
+it was found that only BC1 resulted in a valid asymptotically second-order
+accurate DDM2.
+
+Our results show that the global accuracy and convergence of DDM2 is better
+than DDM1, however both methods perform well and the global convergence rate is
+around two for each.  The error was measured as the L$_2$ norm of the
+difference between an analytic solution and the solution $u_\epsilon$ for
+a given interface width, $\epsilon$.
+
+\Cref{fig:E1,fig:E2} show two of the results, the first one with the Neumann
+boundary conditions and the second with the Robin boundary condition.  The
+results indicate that DDM2 performs slightly better than DDM1.  They also show
+that the approximation BC1 gives more accurate results than BC2.  In
+particular, we found that with BC2 we needed much finer grids to obtain
+convergence for a given $\epsilon$.  For the smallest values of $\epsilon$ we
+were not able to refine the grids enough to obtain valid results.

+\chapter{Conclusions and outlook}
+\label{chap:conclusions}
+This thesis has considered two different problems:  The discretization of
+interface curvature and normal vectors with the level-set method and
+a diffuse-domain approach for solving partial-differential equations (PDEs) in
+complex domains.  In the following, some general concluding remarks and
+recommendations for further work are given.
+
+\section*{Conclusions}
+The first part of the thesis considered the modelling of incompressible
+two-phase flow.  The main motivation was to study two-phase flow phenomena that
+are relevant for compact heat exchangers, such as drop-drop and drop-film
+collisions.  In particular, the thesis addressed a challenge with the
+calculation of interface curvature and normal vectors with the level-set
+method.  Two methods were presented to handle the discretization in the kink
+regions: A curve-fitting discretization method (CFDM) and a local level-set
+extraction (LOLEX) method.  Both methods were shown to be robust in the kink
+regions, where the standard central-difference scheme (CD-2) fails.  Of these
+methods, the LOLEX method is the preferred method, because it relies on a less
+complicated algorithm that easily extends to 3D.
+
+CD-2 and the LOLEX method were used for simulations of drop-film collisions
+that were compared with experiments.  The results showed that CD-2 leads to
+errors in the curvature that cause unphysical pressure spikes during the
+coalescence.  The errors are shown to lead to a dissipation of kinetic energy
+during the collision and to a slower coalescence process.  The LOLEX method was
+shown to prevent these unphysical pressure spikes, and to produce to more
+accurate results.
+
+The second part of the thesis considered the diffuse-domain approach for
+solving PDEs in complex domains.  The main contribution, presented in Paper~E,
+was the derivation of an asymptotically second-order diffuse-domain method
+(DDM2) for solving elliptic problems in complex geometries with Neumann and
+Robin boundary conditions.  The new method is an extension by a high-order
+correction term of the method presented in \cite{Li09}, here called DDM1.  The
+DDM1 and DDM2 were compared, and the results indicated that the DDM2 was
+slightly better than the DDM1.
+
+The thesis has expanded on the results of Paper~E with a new asymptotic
+analysis that shows that DDM1 is in fact also asymptotically second order.
+This analysis helps to explain why the performance of DDM2 presented in Paper~E
+is only slightly better than that of DDM1.  As such, the new analysis leads to
+a better understanding of the DDM1 and the DDM2.
+
+\section*{Outlook}
+The following gives an outline of some possibilities for future work.
+\begin{itemize}
+  \item A natural continuation of this work is to perform more in-depth
+    comparisons of simulations with experiments for the drop-film collision
+    phenomenon that was started in Paper~D.  In addition, it would be
+    interesting to study other two-phase flow phenomena that are relevant for
+    heat-exchanger processes, for instance drop-drop collisions or flow across
+    tube bundles.  The latter requires the treatment of more complex boundaries,
+    which can be handled either with the diffuse-domain method or other methods
+    from the literature.
+  \item Paper~C gave a short comparison of the standard discretization method
+    (CD-2), the direction-difference scheme (DDS), and the curve-fitting
+    discretization scheme (CFDM) applied to the calculation of the normal
+    vectors.  The results showed that the CD-2 leads to inaccurate results in
+    the kink regions.  The DDS gives robust and accurate results in most cases,
+    but an example is given where only the CFDM yields an accurate result.
+    However, the impact of inaccurate calculations of the normal vector should
+    be investigated in more detail.  The normal vector is used both for the
+    solution of the level-set equations \eqref{eq:ls_adeq},
+    \eqref{eq:ls_velextr}, and \eqref{eq:ls_reinit}, and for the calculation of
+    the interface jumps \eqref{eq:jump_pressure} and \eqref{eq:jumptens}, so
+    one can expect that large errors in the calculation of the normal vector
+    may lead to large errors in the numerical solution.  This warrants
+    a further study.
+  \item Mass and heat transfer are obviously an important part of the
+    heat-exchanger processes.  The models that have been used in this thesis
+    should therefore be expanded with additional models for heat transfer and
+    mass transfer to enable the simulation of more relevant phenomena.
+  \item The DDM2 was only derived for problems with Robin and Neumann boundary
+    conditions.  If possible, it should be extended to also work with Dirichlet
+    boundary conditions.
+  \item As explained in Paper~E, we found that we were unable to solve the
+    discrete system of equations when the surface Laplacian part of the
+    correction term for the DDM2 was included.  A further investigation of this
+    problem should be done, and stable numerical methods to solve the full DDM2
+    equations should be developed.
+  \item The diffuse-domain approach is a promising method for solving problems
+    in complex and confined geometries with standard tools and methods.
+    \citet{Aland10} provide a diffuse-domain formulation of the Navier-Stokes
+    Cahn-Hilliard equations for incompressible two-phase flow and use it to
+    compute two-phase flow in both complex and confined geometries.  However,
+    they do not provide an asymptotic analysis of the reformulated equations to
+    show that the system converges.  Such an analysis would be interesting, in
+    particular to verify that the equations do converge to the original problem
+    when the interface width is decreased.
+  \item Finally, it would be interesting to develop a second-order
+    diffuse-domain formulation for the incompressible Navier-Stokes equations.
+    A starting point would be to use the results and techniques from this
+    thesis and Paper~E.

+\chapter{Introduction}
+This thesis considers the mathematical modelling and numerical computation of
+two-phase flows.  It focuses on developing more robust numerical methods to
+calculate the curvature and the normal vector of the interface between the two
+phases.  In addition it considers a diffuse-domain method for solving partial
+differential equations in complex geometries, and it derives an asymptotically
+second-order method for elliptic problems.
+
+\section{Background and motivation}
+Two-phase flows are particular examples of multiphase flows of gas and liquid
+with an interface that separates the two phases.  In the pedantic sense,
+two-phase flow is flow of a single fluid that occurs as two different phases,
+for example steam and water.  However, it is common to be more general, and in
+this thesis we use the term two-phase flow also for immiscible mixtures of
+different fluids, such as water and oil.
+
+Two-phase flows are crucial to a large amount of processes, both in nature and
+in industry.  Examples range from weather phenomena, such as rain drops falling
+through air, to industrial processes, for instance the separation of water from
+oil.  In general, multiphase flow phenomena influence any process where liquids
+and gases are involved.  In the oil and gas industry, most processes are
+two-phase or multiphase flow processes.  Needless to say, the understanding of
+these phenomena is fundamental in the development of new or improved processes.
+
+Consider the international trade of liquefied natural gas (LNG), which is
+a particular branch of the oil and gas industry that has undergone an
+exceptional growth in the last decades.  There is a strong focus both in Norway
+and internationally on producing LNG on large floaters
+(FLNG)\footnote{FLNG facilities do not yet exist, although a facility is under
+  development by Royal Dutch Shell~\cite{Prelude1}.  The construction of this
+  facility was started in 2012, and the first drilling is stated to commence in
+  2013~\cite{Prelude2}.}.  There are a number of both environmental and
+economic advantages of such FLNG facilities.  In particular, FLNG facilities
+would remove the need of long pipelines from the gas fields to the shore, there
+would be no requirement for compression units to pump the gas to the shore, and
+one would not need to construct onshore production facilities.  This would
+significantly reduce the environmental footprint, and would help preserve
+marine and coastal environments.  Since an FLNG facility can be moved to a new
+location when a field has been depleted, it would make it economically viable
+to open up new business opportunities to develop offshore gas fields that would
+otherwise remain stranded.
+
+Moving the LNG production to an offshore facility presents a demanding set of
+challenges.  A particular challenge is that the elements of a conventional LNG
+facility need to fit into an area roughly one quarter the original size.  Heat
+exchangers are among the main challenges in the design and operation of LNG
+plants \cite{Hesselgreaves01}.  Compact and efficient heat exchangers are
+needed to obtain an energy efficient plant with low emissions.  More optimized
+designs require more accurate tools for design and operation.  Such tools can
+only come as a result of an improved physical understanding of the complex
+two-phase flows occurring in the heat exchangers.  This can be achieved by more
+detailed mathematical modelling, together with dedicated laboratory
+observations, cf.\ \cite{Olsen07}.
+
+\section{Overview of methods for two-phase flow simulations}
+In the following, a brief overview is given of different methods for modelling
+two-phase flows where the interface location is known.  In particular, we focus
+on methods that handle the interface evolution.  For more in-depth reviews, see
+for instance \cite{Cristini04,Scardovelli99,Sethian03}.
+
+Interface propagation methods comprise a range of methods that are often
+categorised as either front tracking or front capturing.  Front-tracking
+methods use Lagrangian particles to track the interface
+explicitly~\cite{Tryggvason01}, while front-capturing methods use an Eulerian
+approach to capture the interface implicitly.  Examples of the latter are
+volume-of-fluid methods~\cite{Scardovelli99,Tryggvason11}, phase-field
+methods~\cite{Anderson98,Jacqmin99,Lowengrub98}, and level-set
+methods~\cite{Osher03}.
+
+The main advantages of front-tracking methods are their inherent accuracy and
+that topological changes do not occur without explicit action.  Hence,
+unphysical numerical reconnection does not occur.  This means that if front
+tracking is used for the simulations of two drops that collide, these drops
+will not coalesce due to numerical reconnection or merging.  However, the
+handling of topological changes are challenging, in particular in three
+dimensions~\cite{Shin02}.  Also, there are some issues of numerical
+instabilities, as discussed by \citet{Sethian85} and \citet{Osher88}.
+
+The volume-of-fluid method utilizes a volume-fraction function whose values
+represent the characteristic function of one of the fluid domains.  Its values
+are zero or one, except in those cells cut by the interface.  A considerable
+advantage of the volume-of-fluid method is that it conserves the mass of both
+fluids well.  However, the reconstruction of the interface from volume
+fractions is not simple, and computation of geometric quantities such as the
+interface curvature is not straightforward.  Also, spurious bubbles and drops
+may be created, cf.\ \cite{Lafaurie94}.
+
+The phase-field methods treat the interface in a diffuse manner, where the
+fluid properties, such as density and viscosity, change rapidly but smoothly
+across the interface.  These methods typically solve the coupled
+Cahn-Hilliard/Navier-Stokes equations, where the Cahn-Hilliard equation is
+based on the free energy of an interface~\cite{Cahn57}.  Through this energy
+formulation, one can model more advanced interface physics such as van der
+Waals interactions, electrostatic forces, and fluids with varying
+miscibilities.  However, the phase-field methods require that one resolves very
+small length scales at the interfaces.  This poses a severe restriction on the
+applicability of phase-field methods for two-phase flow, where the length
+scales of the flow are generally much larger than those of the interface.
+
+In this thesis, we have used the level-set method~\cite{Osher88}, which
+implicitly captures the interface as an isocontour of a function defined in the
+entire domain.  The main motivation of this choice is both that the level-set
+method handles topological changes of evolving interfaces automatically,
+cf.~\citet{Sethian03}, and that it is relatively straightforward to implement.
+
+It should be noted that the automatic handling of topological changes is not
+based on physical principles.  For instance, when two interfaces approach each
+other and their distance becomes less than the spacing of the grid, the
+level-set method can no longer resolve both interfaces and so they are merged.
+An important consequence is that the level-set method does not model the
+physics involved in the coalescence process, and in particular in the smaller
+scales of the film-drainage process.  This process involves a wide range of
+length scales, varying from the nanometer scale where van der Waals force are
+active to the length scales of the external flow.  Some effort has been made to
+include the effects of the smaller scales in front-capturing methods,
+cf.~\cite{Nobari96,Tryggvason10}.  Recently, \citet{Kwakkel13} presented
+a level-set/volume-of-fluid method that is coupled with a film-drainage model
+that predicts if and when two colliding droplets will coalesce.  To prevent the
+numerical coalescence, each droplet has its own locally defined level-set
+function.
+
+The level-set method has been used to model several diverse phenomena,
+such as tumour growth~\cite{Macklin06,Macklin05,Macklin08}, propagation of
+wildland fire~\cite{Mallet09}, and computer RAM production~\cite{Melicher08}.
+For a good and thorough introduction to the level-set method, see
+\cite{Osher03}.
+
+A weakness of the level-set method is that it does not conserve the mass of the
+two fluids, in particular in areas of low resolution and/or high curvature.
+Different approaches have been developed to overcome this disadvantage, for
+example the conservative level-set method~\cite{Olsson05,Olsson07}, the
+particle level-set method~\cite{Enright02}, or the coupled
+level-set/volume-of-fluid method~\cite{Sussman00}.
+
+When we use the level-set method to capture the interface for immiscible and
+incompressible two-phase flow simulations, there will be a sharp change in the
+density and viscosity across the interface.  In this thesis we use the
+ghost-fluid method~\cite{Fedkiw99}, which is a sharp-interface method where the
+jumps are included in the spatial discretizations in a sharp manner.  An
+alternative method is the continuous surface-force method introduced by
+\citet{Brackbill92}, where the density and the viscosity are smeared out across
+the interface through a smoothed Heaviside function.
+

+\section{Goal and contribution of the present thesis}
+The main goal of the PhD project has been to develop fundamental knowledge of
+two-phase flow phenomenon that are relevant for compact heat exchangers.
+
+In order to do detailed theoretical studies of phenomena that are relevant for
+compact heat exchangers, we need to consider two-phase flows with mass and heat
+transfer in confined and complex geometries.  One such relevant phenomenon is
+the drop-film collision process \cite{Zhao09}.  Even when restricted to
+isothermal and immiscible flows, this simple phenomenon remains a challenge.
+When the level-set method is used to capture the interface, one must be
+particularly careful about how one calculates the interface curvature and
+normal vector.  For instance, when two drops are in near collision there is
+a kink region in the level-set function between the drops, where the gradient
+is discontinuous, see \cref{fig:curvature-problem}.  This discontinuity may
+lead to large errors in the curvature and the normal vector if it is not taken
+into account in the discretization stencils.

+
+As a step towards computing two-phase flow simulations in confined geometries,
+the thesis has considered the diffuse-domain method~\cite{Li09}.  This is
+a method where partial-differential equations in complex domains are extended
+into larger, regular domains with the use of diffuse approximations of the
+physical boundaries.  The approximations converge asymptotically to the
+original problem when the width of the diffuse boundary is reduced.  With this
+method one can use standard numerical methods to solve equations that
+incorporate complex boundaries.
+
+The main contributions of the present thesis are two new methods to calculate
+the curvature and normal vector in a robust manner with the level-set method.
+These methods are shown to yield more accurate calculations of drop-film and
+drop-drop collisions.  The methods are compared with standard methods and with
+other methods from the literature.
+
+In addition, the thesis presents an extension of a diffuse-domain method by
+a high-order correction term for the solution of elliptic problems in complex
+geometries.  New analysis provided in the thesis improves the understanding of
+the diffuse-domain method, and the derived method is shown to be more accurate
+than the existing diffuse-domain method.
+
+\section{Outline of the thesis}
+The thesis is organised as follows: \Cref{chap:two-phase-flow} gives a brief
+overview of the derivation of the governing equations for two-phase flow.  It
+includes a consideration of the fluid-fluid interface conditions and the
+derivation of a simplified jump tensor for the viscous term at the interface.
+
+\Cref{chap:numerical-methods} gives a detailed description of the numerical
+methods that are used to solve the two-phase flow equations.  In particular, it
+describes the level-set method, which is used to capture the interfaces,
+projection methods that are used to solve the Navier-Stokes equations, and the
+spatial and temporal discretization schemes.  At the end of the chapter, an
+overview of the novel discretization methods for the curvature and the normal
+vector is given.
+
+\Cref{chap:diffuse-domain} gives a short introduction to the diffuse-domain
+method for an elliptic problem with Neumann boundary conditions.  It introduces
+the high-order correction term, and shows that the new method converges
+asymptotically with second-order to the original problem.  The chapter presents
+new analysis that shows that the correction term is not necessary for
+second-order convergence.
+
+In \cref{chap:contributions} the main results of the contributed papers A--E
+are summarized, and the author's contributions are highlighted.  Finally,
+\cref{chap:conclusions} gives concluding remarks and provides an outlook for
+future work.
+
+Full-text versions of the research papers A--E are provided in the Appendices
+at the end of the thesis.

+\chapter{Governing equations for two-phase flow}
+\label{chap:two-phase-flow}
+In this chapter we will give a brief overview of the derivation of the
+governing equations for two-phase flow.  We begin with a consideration of the
+Navier-Stokes equations for single-phase flow.  We then introduce a singular
+surface-force term and derive the Navier-Stokes equations for two-phase flow.
+Finally, we use the Navier-Stokes equations for two-phase flow to derive jump
+conditions at the interface between the phases.
+
+\section{The Navier-Stokes equations for single-phase flow}
+The following is a brief derivation of the Navier-Stokes equations for
+single-phase flows.  For a more thorough derivation of these equations, see for
+instance \citet[§4 and §5]{Aris89} or \citet[Chapter~4]{White03}.
+
+We consider a single-phase, viscous flow in some domain $\Omega$ with boundary
+$\partial\Omega$.  When temperature effects are neglected the flow is described
+by the Cauchy equation
+\begin{equation}
+  \label{eq:cauchy_equation}
+  \rho\left(\cd{\vct u}\right) = \div\tenstr+\rho\vct f,
+\end{equation}
+and the mass conservation equation,
+\begin{equation}
+  \label{eq:cons_of_mass}
+  \pdt\rho + \div(\rho\vct u) = 0.
+\end{equation}
+Here $\rho$ is the fluid density, $\vct u$ is the flow velocity, $t$ is time,
+$\tenstr$ is the stress tensor, $\vct f$ denotes body forces, and $\del$ is
+used to denote the gradient and divergence operators.  The stress tensor for
+Newtonian fluids with zero bulk viscosity is
+\begin{equation}
+  \tenstr = -p\tenI + 2\mu\tenD - \frac 2 3\mu (\trace\tenD) \tenI,
+  \label{eq:viscous_stress_tensor}
+\end{equation}
+where $p$ is the pressure, $\tenI$ is the identity tensor, $\mu$ is the dynamic
+viscosity, and $\trace\tenD$ denotes the trace of the strain-rate tensor
+$\tenD$,
+\begin{equation}
+  \tenD = \frac{1}{2}\left( \grad\vct u + (\grad\vct u)^T \right).
+  \label{eq:deformation_tensor}
+\end{equation}
+For incompressible flow, the mass-conservation equation reduces to
+\begin{equation}
+  \label{eq:navier-stokes-1}
+  \div\vct u = 0,
+\end{equation}
+that is, the velocity field must be divergence free.  If we further assume that
+the viscosity is constant, then it follows that the divergence of the stress
+tensor reduces to
+\begin{equation}
+  \label{eq:stress_tensor}
+  \div\tenstr = -\grad p + \mu\lapl\vct u,
+\end{equation}
+and so the Cauchy equation \eqref{eq:cauchy_equation} becomes
+\begin{equation}
+  \rho\left(\cd{\vct u}\right) = -\grad p + \mu\lapl\vct u + \rho\vct f.
+  \label{eq:navier-stokes-2}
+\end{equation}
+Equations \eqref{eq:navier-stokes-1} and \eqref{eq:navier-stokes-2} are the
+incompressible Navier-Stokes equations for single-phase flow with constant
+viscosity.
+
+\section{The Navier-Stokes equations for two-phase flow}
+We now consider an immiscible two-phase flow of two Newtonian fluids, each with
+its own viscosity and density.  We let $\Omega_1$ and $\Omega_2$ denote the
+domains occupied by fluid 1 and fluid 2, respectively, and let the interface
+between the fluids be denoted by $\Gamma$.  Then $\Omega
+= \Omega_1\cup\Omega_2$ and $\partial\Omega
+= (\partial\Omega_1\cup\partial\Omega_2)\setminus\Gamma$ are the fluid domain
+and its boundary, respectively.  See \cref{fig:domain} for an illustration of
+a two-phase flow domain.

+  \caption{An illustration of a two-phase flow domain.  The interface $\Gamma$
+    separates the two phases $\Omega_1$ and $\Omega_2$.}
+  \label{fig:domain}
+\end{figure}
+
+The extension of the single-phase model to account for two fluids can be made
+by adding a singular surface-force term to represent the effects of surface
+tension between the fluids.  We assume that the surface tension is constant, in
+which case the singular surface force can be defined as
+\begin{equation}
+  \funssf(\vct x,t)
+  = \int_{\Gamma}\sigma\kappa\vct n\delta(\vct x - \vct x_I(\vct s))\dif\vct s,
+  \label{eq:ssf}
+\end{equation}
+where $\sigma$ is the surface tension, $\kappa$ is the local curvature, $\vct
+n$ is the normal vector, $\delta$ is the Dirac delta function, and $\vct
+x_I(\vct s)$ is a parametrisation of the interface.  Thus the Navier-Stokes
+equations for immiscible and incompressible two-phase flow are
+\begin{align}
+  \label{eq:ns1}
+  \div\vct u &= 0, \\
+  \label{eq:ns2}
+  \rho\left(\cd{\vct u}\right) &= -\grad p + \mu\lapl\vct u
+    + \rho\vct f + \funssf.
+\end{align}
+
+\section{Fluid-fluid interface conditions}
+The surface-tension force and the jump in viscosity and density across the
+interface $\Gamma$ lead to a set of interface conditions that must be satisfied
+along the interface $\Gamma$.  The following is a brief derivation of these
+conditions.
+
+First, we only consider flows where there is no mass transfer, which implies
+that
+\begin{equation}
+  \jmp{\vct u}\cdot\vct n = 0,
+\end{equation}
+where $\jmp{\cdot}$ denotes the jump at the interface, for instance $\jmp{\mu}
+= \mu_2 - \mu_1$.  Further, for viscous flows there is no slip at the
+interface, and thus the tangential velocity component of the two fluids must be
+equal at the interface,
+\begin{equation}
+  \jmp{\vct u}\cdot\vct t = 0.
+\end{equation}
+It follows that
+\begin{align}
+  \label{eq:jmpu}
+  \jmp{\vct u} &= 0, \\
+  \label{eq:jmpJut}
+  \jmp{\grad \vct u}\cdot\vct t &= 0.
+\end{align}
+The latter is a direct consequence of the former.  Both fluids are
+incompressible, which gives the trivial identity $\jmp{\div\vct u} = 0$.  If we
+use the identity
+\begin{equation}
+  \div\vct u
+    = \vct n\cdot\grad\vct u\cdot\vct n + \vct t\cdot\grad\vct u\cdot\vct t
+  \label{eq:divuident}
+\end{equation}
+together with \eqref{eq:jmpJut} we get
+\begin{equation}
+  \vct n\cdot\jmp{\grad\vct u}\cdot\vct n = 0,
+  \label{eq:jmpngradun}
+\end{equation}
+which means that the normal component of the normal derivative of the velocity
+field is continuous across the interface.  Note that in \eqref{eq:divuident}
+and in similar expressions in the following, the nabla operator is only applied
+to $\vct u$, not the normal and tangential vectors that follow.

+  \end{tikzpicture}
+  \caption{A sketch of the control volume $\Omega_\epsilon$ that covers the
+    interface, $\Gamma$.}
+  \label{fig:domain_omega_epsilon}
+\end{figure}%
+Next, we consider the conservation of momentum.  We define a control volume
+\begin{equation}
+  \Omega_{\epsilon} = \set{\vct x \in \Omega}{\min_{\vct x_I \in \Gamma}|\vct
+    x - \vct x_I| \leq \epsilon},
+\end{equation}
+where $\epsilon > 0$, see \cref{fig:domain_omega_epsilon}.  We then integrate
+the Cauchy equation \eqref{eq:cauchy_equation} with the added singular
+surface-force term over the domain~$\Omega_\epsilon$,
+\begin{multline}
+  \intoepdx{\rho\td{\vct u}}
+    = \intoepdx{\div\tenstr} + \intoepdx{\rho\vct f} \\
+      + \intoepdx{ \int_{\Gamma}\sigma\kappa\vct n\delta(\vct x - \vct
+        x_I(\vct s))\dif\vct s}.
+\end{multline}
+Here $\tdi{\vct u} = \partial\vct u/\partial t + \vct u\cdot\grad\vct u$
+denotes the convective derivative.  Now we apply the Gauss theorem and change
+the order of integration in the last term to obtain
+\begin{equation}
+  \intoepdx{\rho\td{\vct u}} = \intdoepds{\tenstr\cdot\vct n}
+    + \intoepdx{\rho\vct f} + \int_\Gamma\sigma\kappa\vct n\dif\vct s.
+\end{equation}
+If we let $\epsilon$ go to zero, the left-hand side and the second term on the
+right-hand side vanish, and we get
+\begin{equation}
+  0 = \int_\Gamma\left( \jmp{\tenstr}\cdot\vct n + \sigma\kappa\vct
+    n \right)\dif s.
+  \label{eq:stressjumpint}
+\end{equation}
+Since the derivation above is also valid for any subset of $\Omega_\epsilon$
+containing a part of $\Gamma$, \eqref{eq:stressjumpint} must hold for any part
+of $\Gamma$.  Therefore
+\begin{equation}
+  0 = \jmp{\vct T}\cdot\vct n + \sigma\kappa\vct n.
+\end{equation}
+With $\vct T = -p\vct I + 2\mu\vct D$ we finally get the interface condition
+for the stresses,
+\begin{equation}
+  \label{eq:stress_jump}
+  \jmp{p}\vct n - \jmp{2\mu\tenD}\cdot\vct n = \sigma\kappa\vct n.
+\end{equation}
+The surface tension force is seen to introduce a discontinuity in the normal
+stresses across the interface.  The tangential stresses are continuous.
+
+\section{Interface conditions for the pressure and the viscous term}
+The previous section gave a brief derivation of the interface conditions for
+immiscible and incompressible two-phase flow without mass transfer.  In order
+to use these conditions for the discretization of the Navier-Stokes equations
+\eqref{eq:ns1} and \eqref{eq:ns2}, we need to rewrite them into a more suitable
+form.  In particular, we want to find explicit expressions for the jump in the
+pressure $\jmp p$ and the viscous term $\jmp{\mu\grad\vct u}$.  The following
+derivation is based on \cite{Hansen05} and \cite{Kang00}.
+
+First, a jump condition for the pressure is obtained by taking the inner
+product of \eqref{eq:stress_jump} with the normal vector $\vct n$,
+\begin{equation}
+  \jmp p = \vct n\cdot\jmp{2\mu\tenD}\cdot\vct n + \sigma\kappa
+      = 2\jmp{\mu}\vct n\cdot \grad\vct u \cdot\vct n
+        + \sigma\kappa,
+  \label{eq:jump_pressure}
+\end{equation}
+where \eqref{eq:jmpngradun} was used for the second equality.
+
+To find the jump in the viscous term, it is first decomposed into an interface
+normal coordinate system as
+\begin{equation}
+  \begin{split}
+    \jmp{\mu\grad\vct u} &=
+  \left(\vct n\cdot\jmp{\mu\grad\vct u}\cdot\vct n\right)\vct n\otimes\vct n +
+  \left(\vct t\cdot\jmp{\mu\grad\vct u}\cdot\vct t\right)\vct t\otimes\vct t
+        \\ &\quad+
+  \left(\vct n\cdot\jmp{\mu\grad\vct u}\cdot\vct t\right)\vct n\otimes\vct t +
+  \left(\vct t\cdot\jmp{\mu\grad\vct u}\cdot\vct n\right)\vct t\otimes\vct n,
+  \end{split}
+\end{equation}
+where $\otimes$ denotes the dyadic product.  We already showed that
+$\jmp{\grad\vct u}\cdot\vct t = 0$ and $\vct n\cdot\jmp{\grad\vct u}\cdot\vct
+n = 0$, cf.\ \eqref{eq:jmpJut} and \eqref{eq:jmpngradun}, which gives
+\begin{align}
+  \vct n\cdot\jmp{\mu\grad\vct u}\cdot\vct n &=
+    \jmp{\mu}\,\vct n\cdot\grad\vct u\cdot\vct n, \\
+  \vct t\cdot\jmp{\mu\grad\vct u}\cdot\vct t &=
+    \jmp{\mu}\,\vct t\cdot\grad\vct u\cdot\vct t, \\
+  \vct n\cdot\jmp{\mu\grad\vct u}\cdot\vct t &=
+    \jmp{\mu}\,\vct n\cdot\grad\vct u\cdot\vct t.
+\end{align}
+We then take the inner product of \eqref{eq:stress_jump} with $\vct t$, which
+gives
+\begin{equation}
+  \vct t\cdot\jmp{\mu\left(\grad\vct u + (\grad\vct u)^T \right)}\cdot\vct n
+  = \vct t\cdot\jmp{\mu\grad\vct u} \cdot\vct n
+    + \jmp{\mu}\vct n\cdot\grad\vct u \cdot\vct t
+  = 0,
+\end{equation}
+or
+\begin{equation}
+  \vct t\cdot\jmp{\mu\grad\vct u}\cdot\vct n =
+    - \jmp{\mu}\vct n\cdot\grad\vct u \cdot\vct t.
+\end{equation}
+The jump in the viscous term becomes
+\begin{multline}
+  \jmp{\mu\grad\vct u} = \jmp{\mu} \Big(
+       (\vct n\cdot\grad\vct u\cdot\vct n)\vct n\otimes\vct n
+     + (\vct n\cdot\grad\vct u\cdot\vct t)\vct n\otimes\vct t \\
+     - (\vct n\cdot\grad\vct u\cdot\vct t)\vct t\otimes\vct n
+     + (\vct t\cdot\grad\vct u\cdot\vct t)\vct t\otimes\vct t \Big).
+\end{multline}
+This can be simplified further by noting that
+\begin{equation}
+  (\grad\vct u\cdot t)\otimes\vct t
+  = (\vct n\cdot\grad\vct u\cdot\vct t)\vct n\otimes\vct t
+    + (\vct t\cdot\grad\vct u\cdot\vct t)\vct t\otimes\vct t.
+\end{equation}
+Thus we obtain the expression for the jump in the viscous term that has been
+used in the present work,
+\begin{multline}
+  \jmp{\mu\grad\vct u} = \jmp{\mu} \Big(
+       (\vct n\cdot\grad\vct u\cdot\vct n)\vct n\otimes\vct n
+     - (\vct n\cdot\grad\vct u\cdot\vct t)\vct t\otimes\vct n \\
+     + (\grad\vct u\cdot\vct t)\otimes\vct t \Big).
+  \label{eq:jumptens}
+\end{multline}
+

+\chapter{Numerical methods}
+\label{chap:numerical-methods}
+This chapter describes the numerical methods that have been used in this thesis
+to solve the Navier-Stokes equations for two-phase flow.  First, a brief
+introduction to the level-set method is given, which is followed by an outline
+of the two projection methods that have been used to solve the Navier-Stokes
+equations.  The spatial and temporal discretization methods are then
+summarized, and at the end of the chapter the new methods to calculate the
+curvature and the normal vectors are presented.
+
+\section{The level-set method}
+\label{sec:level-set}
+In order to solve the Navier-Stokes equations for two-phase flow, we need to
+know the location of the interface.  The level-set method proposed by
+\citet{Osher88} allows us to capture the interface location as the zero level
+set of the level-set function $\varphi(\vct x,t)$.  The level-set function is
+typically defined as a signed-distance function,
+\begin{equation}
+  \varphi(\vct x,t) = \begin{cases}
+     d(\vct x,t) & \text{if } \vct x\in\Omega_2, \\
+    -d(\vct x,t) & \text{if } \vct x\in\Omega_1, \\
+  \end{cases}
+\end{equation}
+where $d(\vct x,t)$ is the shortest distance to the interface $\Gamma$,
+\begin{equation}
+  d(\vct x,t) = \min_{\vct x_I \in \Gamma} |\vct x - \vct x_I|.
+\end{equation}
+Thus the interface can be defined implicitly as
+\begin{equation}
+  \Gamma(t) = \set{\vct x\in\Omega}{\varphi(\vct x,t)=0},
+              \quad t\in \mathbb R^+.
+\end{equation}
+
+The position of the interface is updated by solving an advection equation for
+$\varphi$,
+\begin{equation}
+  \label{eq:ls_adeq}
+  \pdt{\varphi} + \vct{\hat u}\cdot\grad\varphi = 0,
+\end{equation}
+where $\vct{\hat u}$ is the velocity at the interface extended to the entire
+domain.  We extend the interface velocity through solving
+a velocity-extrapolation equation,
+\begin{equation}
+  \label{eq:ls_velextr}
+  \pd{\vct{\hat u}}{\tau} + S(\varphi)\vct n\cdot\grad\vct{\hat u} = 0,
+  \quad \vct{\hat u}_{\tau=0} = \vct u,
+\end{equation}
+to steady state, cf.\ \cite{Adalsteinsson99,Zhao96}.  Here $\tau$ is
+a pseudo-time and $S$ is a smeared sign function which is equal to zero at the
+interface,
+\begin{equation}
+  S(\varphi) = \frac{\varphi}{\sqrt{\varphi^2+2\Delta x^2}}.
+\end{equation}
+
+When we solve the level-set equation \eqref{eq:ls_adeq}, the non-uniform
+advection will distort the signed-distance property of the level-set function,
+and numerical dissipation error adds to this distortion.  The level-set
+function is therefore reinitialized regularly by solving
+\begin{equation}
+  \label{eq:ls_reinit}
+  \begin{split}
+    \pd{\varphi}{\tau} + S(\varphi_0)(|\grad\varphi|-1) &= 0, \\
+    \varphi(\vct x,0) &= \varphi_0(\vct x),
+  \end{split}
+\end{equation}
+to steady state as proposed by \citet{Sussman94}.  The level-set function just
+before initialization is used as the initial condition $\varphi_0$.
+
+The level-set equations \eqref{eq:ls_adeq}, \eqref{eq:ls_velextr}, and
+\eqref{eq:ls_reinit} are discretized in time and space as described in the
+following sections.  The method presented by \citet{Adalsteinsson95} is used to
+improve the computational speed.  The method is often called the narrow-band
+method, since the level-set function is only updated in a narrow band across
+the interface at each time step.
+
+One of the advantages of the level-set method is that normal vectors and
+curvatures can be readily calculated from the level-set function, that is,
+\begin{align}
+  \label{eq:norm}
+  \vct n &= \frac{\grad\varphi}{|\grad\varphi|}, \\
+  \label{eq:curv}
+  \kappa &= \div\left(\frac{\grad\varphi}{|\grad\varphi|}\right).
+\end{align}

+\section{Projection methods}
+\label{sec:projection-method}
+We have employed two different projection methods in this thesis to solve the
+incompressible Navier-Stokes equations for two-phase flow \eqref{eq:ns1} and
+\eqref{eq:ns2}.  Papers A, B, and C used the direct projection
+scheme~1~(DP1)~\cite{Hansen05}, and Paper D used the more standard Chorin
+projection method \cite{Chorin68}.
+
+The projection methods are a family of methods for the solution of the
+incompressible Navier-Stokes equations that are based on the Helmholtz-Hodge
+theorem.  This theorem states that an arbitrary vector field can be decomposed
+into a divergence-free part and a rotation-free part.  That is, any vector
+field $\vct a$ can be written as
+\begin{equation}
+  \vct a = \vct a' + \grad\psi,
+\end{equation}
+where $\vct a'$ is a vector with $\div\vct a' = 0$ and $\psi$ is a scalar
+potential.  The proof of this theorem can be found in for instance
+\cite[§3.44]{Aris89} or \cite{Chorin00}.
+
+\subsection{The direct projection scheme 1}
+The DP1 was developed by \citet{Hansen05} and is based on a direct application
+of the Helmholtz-Hodge theorem.  We assume that the velocity $\vct u$ is
+sufficiently smooth, and then rewrite \eqref{eq:navier-stokes-2} to get
+\begin{equation}
+  \label{eq:divFreeVel}
+  \pdt{\vct u} = \vct w - \frac{\grad p}{\rho},
+\end{equation}
+where
+\begin{equation}
+  \vct w = - (\vct u\cdot\grad)\vct u + \nu\grad^2\vct u + \vct f.
+  \label{eq:continuousRightHandVector}
+\end{equation}
+The divergence of \eqref{eq:divFreeVel} yields a Poisson equation for the
+pressure,
+\begin{equation}
+  \div\left(\frac{\grad p}{\rho}\right) = \div\vct w.
+  \label{eq:PoissonDP1}
+\end{equation}
+The DP1 scheme follows from a direct numerical discretization of the above
+equations.  First, $\vct w$ is calculated with
+\eqref{eq:continuousRightHandVector}.  Then the pressure is found by solving
+the Poisson equation \eqref{eq:PoissonDP1}.  Finally, an Euler step is used to
+solve \eqref{eq:divFreeVel}, that is,
+\begin{equation}
+  \vct u^{n+1} = \vct u^n + \Delta t\left(\vct w - \frac{\grad p}{\rho}\right).
+  \label{eq:dp1-update}
+\end{equation}
+
+\subsection{The Chorin projection method}
+The Chorin projection method was presented by \citet{Chorin68}, and is today
+one of the standard methods for solving the Navier-Stokes equations, e.g.\
+\cite{Walker12}.  The method is briefly presented in the following.
+
+Let $\Delta t$ be the time step, and consider the discretization of the
+momentum equation \eqref{eq:navier-stokes-2} with the forward Euler method,
+\begin{equation}
+  \frac{\vct u^{n+1} - \vct u^n}{\Delta t}
+  = -\vct u^n\cdot\grad\vct u^n
+    - \frac{\grad p^{n+1}}{\rho} + \frac\mu\rho\lapl\vct u^n + \vct f,
+  \label{eq:discmomeq}
+\end{equation}
+where $\vct u^n\equiv\vct u(\vct x,n\Delta t)$ and $p^n\equiv p(\vct x,n\Delta
+t)$ are assumed known at time level $n$.  Note that the pressure gradient is
+evaluated at time level $n+1$.  Next, to solve \eqref{eq:discmomeq} in two
+steps, we introduce the intermediate velocity field $\vct u^\star$,
+\begin{equation}
+  \frac{\vct u^{n+1} - \vct u^\star + \vct u^\star - \vct u^n}{\Delta t}
+  = -\vct u^n\cdot\grad\vct u^n
+    - \frac{\grad p^{n+1}}{\rho} + \frac\mu\rho\lapl\vct u^n + \vct f,
+\end{equation}
+which is chosen such that
+\begin{align}
+  \label{eq:ustar}
+  \frac{\vct u^\star - \vct u^n}{\Delta t}
+    &= -\vct u^n\cdot\grad\vct u^n + \frac\mu\rho\lapl\vct u^n + \vct f, \\
+  \label{eq:unext}
+  \frac{\vct u^{n+1} - \vct u^\star}{\Delta t} &= - \frac{\grad p^{n+1}}{\rho}.
+\end{align}
+From \eqref{eq:ustar} we get an explicit expression for $\vct u^\star$,
+\begin{equation}
+  \vct u^{\star} = \vct u^n
+    + \Delta t\left(-\vct u^n\cdot\grad\vct u^n
+        + \frac\mu\rho\,\lapl\vct u^n + \vct f\right).
+\end{equation}
+Next, the divergence of \eqref{eq:unext} and $\div\vct u^{n+1} = 0$ yields
+a Poisson equation for the pressure,
+\begin{equation}
+  \div\left(\frac{\grad p^{n+1}}{\rho}\right)
+    = \frac{\div\vct u^\star}{\Delta t}.
+  \label{eq:PoissonChorin}
+\end{equation}
+Finally, we obtain for \eqref{eq:unext}
+\begin{equation}
+  \vct u^{n+1} = \vct u^\star - \Delta t\frac{\grad p^{n+1}}{\rho}.
+  \label{eq:velcorrection}
+\end{equation}
+
+\section{Spatial discretization}
+\label{sec:x-discr}
+The governing equations \eqref{eq:ns1}, \eqref{eq:ns2}, \eqref{eq:ls_adeq},
+\eqref{eq:ls_velextr}, and \eqref{eq:ls_reinit} are discretized on a staggered
+grid~\cite{Harlow65}, where the scalar values are located at the cell centres
+and the vector values are located at the cell edges, see
+\cref{fig:staggered-grid}.  The domain boundary coincides with cell edges, and
+the fixed grid spacing is $\Delta x$ in the $x$ direction and $\Delta y$ in the
+$y$ direction.

+  \caption{An illustration of a small part of a uniform staggered grid, where

+  \label{fig:staggered-grid}
+\end{figure}
+
+The $x$- and $y$-derivatives, divergence, and Laplacian operators are
+discretized by the second-order central-difference scheme,
+\begin{align}
+  \left. G_x p \right|_{i+\frac 1 2,j}
+    &= \frac{p_{i+1,j} - p_{i,j}}{\Delta x}, \\
+  \left. G_y p \right|_{i,j+\frac 1 2}
+    &= \frac{p_{i,j+1} - p_{i,j}}{\Delta y}, \\
+  \left. \vct D \cdot \vct u \right|_{i,j}
+    &=   \frac{u_{i+1/2,j} - u_{i-1/2,j}}{\Delta x}
+       + \frac{v_{i,j+1/2} - v_{i,j-1/2}}{\Delta y}, \\

+       + \frac{p_{i,j+1} - 2p_{i,j} + p_{i,j-1}}{(\Delta y)^2},
+\end{align}
+respectively.  Here $\vct u = (u,v)$ is a vector and $p$ is a scalar.  Note
+that the gradient of a scalar is a vector and has values located at the cell
+edges.  These definitions are consistent with the staggered grid, since the
+gradient returns a vector with components defined on the cell faces, while the
+divergence and the Laplacian returns a scalar defined at the cell centres.
+
+\subsection{Advective terms}
+The advective terms, $\vct u\cdot\grad\vct u$ in the momentum equation
+\eqref{eq:ns2} and $\vct{\hat u}\cdot\grad\varphi$ in the level-set equation
+\eqref{eq:ls_adeq}, and the normal derivative $\vct n\cdot\grad\vct{\hat u}$ in
+the velocity-extrapolation equation \eqref{eq:ls_velextr} are discretized with
+the weighted essentially non-oscillatory (WENO) scheme, cf.~\cite{Fedkiw99}
+and~\cite{Jiang96}.  The WENO scheme is a high-order upwind scheme that is
+fifth-order accurate in smooth regions.  In nonsmooth regions the accuracy is
+reduced to a minimum of third order.  The following is a brief outline of the
+WENO scheme.
+
+First, when we calculate the advective term for the velocity, the vector
+components are required on all cell edges.  That is, we must interpolate the
+$x$-component of the velocity to the location of the $y$-component of the
+velocity and vice versa.  To do this we use a linear interpolation,
+\begin{align}
+  u_{i,j+\frac 1 2} &= \frac 1 4\left(
+      u_{i-\frac 1 2,j  } + u_{i-\frac 1 2,j+1}
+    + u_{i+\frac 1 2,j+1} + u_{i+\frac 1 2,j  } \right), \\
+  v_{i+\frac 1 2,j} &= \frac 1 4\left(
+      v_{i,  j-\frac 1 2} + v_{i+1,j-\frac 1 2}
+    + v_{i+1,j+\frac 1 2} + v_{i  ,j+\frac 1 2} \right).
+\end{align}
+
+Similarly, when we calculate the advective term for the level-set function
+$\varphi$, we first interpolate the velocity to the scalar grid,
+\begin{align}
+  u_{i,j} &= \frac 1 2\left( u_{i+\frac 1 2,j} + u_{i-\frac 1 2,j} \right), \\
+  v_{i,j} &= \frac 1 2\left( v_{i,j+\frac 1 2} + v_{i,j-\frac 1 2} \right).
+\end{align}
+
+We now consider the WENO scheme for the advective operator in 1D at the point
+$x_{i+\frac 1 2}$.  The scheme extends naturally to higher dimensions.  First,
+if $u_{i+\frac 1 2} = 0$, then
+\begin{equation}
+  \left. u\pd u x \right|_{i+\frac 1 2} = 0.
+\end{equation}
+Otherwise we need to calculate a set of five differences that depend on the
+upwind direction.  The differences are denoted $\Delta v_k$ for $k=1,\dots,5$.
+If $u_{i+\frac 1 2}>0$, then we calculate
+\begin{equation}
+  \Delta v_k = \frac{u_{i+\frac{2k-5} 2} - u_{i+\frac{2k-7} 2}}{\Delta x}.
+\end{equation}
+Otherwise if $u_{i+\frac 1 2}<0$, we calculate
+\begin{equation}
+  \Delta v_k = \frac{u_{i-\frac{2k-9} 2} - u_{i-\frac{2k-7} 2}}{\Delta x}.
+\end{equation}
+Next we calculate expressions for the smoothness of three substencils,
+\begin{align}
+  S_1 &= \frac{13}{12}(\Delta v_1 - 2\Delta v_2 + \Delta v_3)^2
+    + \frac 1 4 (\Delta v_1 - 4\Delta v_2 + 3\Delta v_3)^2, \\
+  S_2 &= \frac{13}{12}(\Delta v_2 - 2\Delta v_3 + \Delta v_4)^2
+    + \frac 1 4 (\Delta v_2 - \Delta v_4)^2, \\
+  S_3 &= \frac{13}{12}(\Delta v_3 - 2\Delta v_4 + \Delta v_5)^2
+    + \frac 1 4 (3\Delta v_3 - 4\Delta v_4 + \Delta v_5)^2,
+\end{align}
+where a small $S$ indicates a smooth substencil.  These smoothness factors are
+then used to compute weights for the substencils,
+\begin{equation}
+  w_k = \frac{b_k}{b_1+b_2+b_3},
+\end{equation}
+for $k = 1,2,3$, where
+\begin{equation}
+  b_1 = \frac 1 {10}\frac 1 {(\epsilon+S_1)^2},\quad
+  b_2 = \frac 6 {10}\frac 1 {(\epsilon+S_2)^2},\quad
+  b_3 = \frac 3 {10}\frac 1 {(\epsilon+S_3)^2}.
+\end{equation}
+Here $\epsilon$ is a regularization parameter that is used to avoid division by
+zero.  We have used $\epsilon = 10^{-6}$ in this work.  Finally, the WENO
+scheme for the gradient becomes
+\begin{multline}
+  \left. \pd u x \right|_{i+\frac 1 2} \simeq
+      w_1\left(\frac 1 3\Delta v_1 - \frac 7 6\Delta v_2
+        + \frac{11} 6 \Delta v_3\right) \\
+    + w_2\left(-\frac 1 6\Delta v_2 + \frac 5 6\Delta v_3
+        + \frac 1 3 \Delta v_4\right) \\
+    + w_3\left(\frac1 3\Delta v_3 + \frac 5 6\Delta v_4
+        - \frac 1 6 \Delta v_5\right).
+\end{multline}
+
+\subsection{The viscous term}
+The viscous term $\mu\lapl\vct u$ in the Navier-Stokes equations is discretized
+by standard second-order central differences using the ghost-fluid method
+(GFM)~\cite{Fedkiw99,Kang00,Liu00}.  This method includes the jump in the
+viscous term at the interface \eqref{eq:jumptens} in the discretization stencil
+in a sharp manner.
+
+In the following we present the GFM scheme in the one-dimensional case.  The
+extension to higher dimensions is straightforward.  In order to simplify the
+notation, we omit the half indices and let $k\equiv i+\frac 1 2$.  Further, we
+consider a general case where
+\begin{equation}
+  \jmp u = a_\Gamma, \qquad \jmp{\mu\pd u x} = b_\Gamma.
+\end{equation}
+For the viscous term, $a_\Gamma = 0$, cf.\ \eqref{eq:jmpu}, and $b_\Gamma$ is
+given by the jump tensor~\eqref{eq:jumptens}.  The jump tensor is calculated at
+the cell centres near the interface with the second-order central-difference
+scheme.  It is then interpolated linearly to the cell edges, from where it is
+again interpolated linearly to the interface when needed.
+
+If the interface does not cross the stencil, then the GFM scheme reduces to the
+standard second-order central-difference stencil.  Else there are four
+stencils, depending on the location of the interface.  One such interface
+configuration is sketched in \cref{fig:gfm-scheme-example}.  In all the
+stencils, $\theta$ is defined as the relative distance from the interface to
+the node on the left, for instance
+\begin{equation}
+  \theta = \frac{|\varphi_{k}|}{|\varphi_{k}| + |\varphi_{k+1}|},
+\end{equation}
+where $\varphi_k$ and $\varphi_{k+1}$ are the level-set function values
+linearly interpolated to the vector grid.  The four stencils are given below,
+where $h\equiv\Delta x$.
+\begin{enumerate}
+  \item Phase 1 is to the left and interface lies between $k$ and $k+1$:
+    \begin{align}
+      \begin{split}
+        \left.\pd{} x\left(\mu\pd u x\right)\right|_{x_k}
+          &= \frac{\hat\mu\left(u_{k+1} - u_{k}\right)
+                 - \mu_1\left(u_{k} - u_{k-1}\right)}{h^2} \\
+          &\qquad
+             - \frac{\hat\mu a_\Gamma}{h^2}
+             - \frac{\hat\mu b_\Gamma (1-\theta)}{\mu_2 h},
+      \end{split} \\

+    \end{align}
+  \item Phase 1 is to the left and interface lies between $k-1$ and $k$:

+          &= \frac{\mu_2\left(u_{k+1} - u_{k}\right)
+                - \hat\mu\left(u_{k} - u_{k-1}\right)}{h^2} \\

+      \end{split} \\
+      \hat\mu &= \frac{\mu_1\mu_2}{\theta\mu_2 + (1-\theta)\mu_1}.
+    \end{align}
+  \item Phase 2 is to the left and interface lies between $k$ and $k+1$:
+    \begin{align}
+      \begin{split}
+        \left.\pd{} x\left(\mu\pd u x\right)\right|_{x_k}
+          &= \frac{\hat\mu\left(u_{k+1} - u_{k}\right)
+                - \mu_2\left(u_{k} - u_{k-1}\right)}{h^2} \\
+          &\qquad
+            + \frac{\hat\mu a_\Gamma}{h^2}
+            + \frac{\hat\mu b_\Gamma (1-\theta)}{\mu_1 h},
+      \end{split} \\
+      \hat\mu &= \frac{\mu_1\mu_2}{\theta\mu_1 + (1-\theta)\mu_2}.
+    \end{align}
+  \item Phase 2 is to the left and interface lies between $k-1$ and $k$:
+    \begin{align}
+      \begin{split}
+        \left.\pd{} x\left(\mu\pd u x\right)\right|_{x_k}
+          &= \frac{\mu_1\left(u_{k+1} - u_{k}\right)
+                - \hat\mu\left(u_{k} - u_{k-1}\right)}{h^2} \\

+      \hat\mu &= \frac{\mu_1\mu_2}{\theta\mu_1 + (1-\theta)\mu_2}.

+\subsection{Pressure Poisson equation}
+\label{sec:pressure-poisson}
+The Laplace operator in the Poisson equations \eqref{eq:PoissonDP1} and
+\eqref{eq:PoissonChorin} is also discretized by standard second-order central
+differences using the GFM~\cite{Kang00,Liu00}.  The GFM was discussed in the
+previous section, where stencils were given for the viscous term in the
+one-dimensional case.  For the pressure, the stencils are the same except we
+use $p$ instead of $u$, and $1/\rho$ and $1/\hat\rho$ instead of $\mu$ and
+$\hat\mu$.  To find the jump in the pressure at the interface, $\jmp
+p = a_\Gamma$, the jump condition \eqref{eq:jump_pressure} is calculated at the
+cell centres and then interpolated to the interface.  In addition, we use that
+$b_\Gamma = 0$, which is justified by \citet[Section~3.7]{Kang00}.
+
+The resulting linear system for the pressure is solved with a solver from the
+Portable, Extensible Toolkit for Scientific Computation (PETSc)~\cite{PETSc}.
+PETSc makes available a large selection of solvers.  In most cases, we used the
+direct solver based on LU factorisation or the conjugate gradient method with
+incomplete Cholesky factorisation.  In some cases, we used the GMRES solver
+with a preconditioner, either incomplete LU factorisation or an algebraic
+multigrid method.  See \cite{PETSc} for more details and a list of available
+methods, and see for example~\cite{Iserles09} or~\cite{Saad03} for an
+introduction to linear solvers.
+
+Finally, the gradient of the pressure, used in \eqref{eq:divFreeVel} and
+\eqref{eq:velcorrection}, is also calculated with the GFM.  In one dimension,
+the stencil is
+\begin{align}
+  \left. \frac 1 \rho \pd p x\right|_{i+\frac 1 2}
+           &= \frac 1 {\hat\rho} \frac{(p_{i+1} - a_\Gamma) - p_i} h, \\
+  \hat\rho &= \theta\rho_1 + (1-\theta)\rho_2,
+\end{align}
+if $\phi_i\leq 0$ and $\phi_{i+1}>0$, or else
+\begin{align}
+  \left. \frac 1 \rho \pd p x\right|_{i+\frac 1 2}
+           &= \frac 1 {\hat\rho} \frac{(p_{i+1} + a_\Gamma) - p_i} h, \\
+  \hat\rho &= \theta\rho_2 + (1-\theta)\rho_1,
+\end{align}
+where
+\begin{equation}
+  \theta = \frac{|\varphi_{i}|}{|\varphi_{i}| + |\varphi_{i+1}|}.
+\end{equation}
+
+\section{Temporal discretization}
+\label{sec:t-discr}
+The temporal discretization is done with the explicit strong
+stability-preserving Runge-Kutta (SSP-RK) schemes, see
+\cite{Ketcheson05,Shu88}.  The idea behind the SSP-RK schemes is to preserve
+the stability of a low-order method when it is extended to higher order.  It is
+argued in \cite{Gottlieb01} that if one extends the forward Euler method, which
+is total variation diminishing (TVD) for a suitable discretization of a scalar
+conservation law, to a non-SSP higher-order method, then overshoots may occur
+at discontinuities.
+
+An SSP-RK method can be written as a convex sum of explicit Euler steps with
+time step $\Delta t$,
+\begin{equation}
+  \mathcal E\left(x^n\right) = x^n + \Delta t \mathcal F(x^n,t^n).
+\end{equation}
+where $\mathcal F$ is the residual of the PDE to be solved.  In this thesis we
+have used two methods:  The third-order three-stage SSP-RK method~\cite{Shu88},
+\begin{equation}
+  \begin{split}
+    x^{(1)} &= \mathcal E\left(x^n\right), \\
+    x^{(2)} &= \frac 3 4 x^n + \frac 1 4\mathcal E\left(x^{(1)}\right), \\
+    x^{n+1} &= \frac 1 3 x^n + \frac 2 3\mathcal E\left(x^{(2)}\right),
+  \end{split}
+  \label{eq:ssprk33}
+\end{equation}
+and the third-order four-stage SSP-RK method~\cite{Kraaijevanger91},
+\begin{equation}
+  \begin{split}
+    x^{(1)} &= \frac 1 2 x^n + \frac 1 2\mathcal E\left(x^n\right), \\
+    x^{(2)} &= \frac 1 2 x^{(1)} + \frac 1 2\mathcal E\left(x^{(1)}\right), \\
+    x^{(3)} &= \frac 2 3 x^n + \frac 1 6 x^{(2)}
+               + \frac 1 6\mathcal E\left(x^{(2)}\right), \\
+    x^{n+1} &= \frac 1 2 x^{(3)} + \frac 1 2\mathcal E\left(x^{(3)}\right).
+  \end{split}
+  \label{eq:ssprk34}
+\end{equation}
+
+The semi-discretized velocity-extrapolation equation \eqref{eq:ls_velextr} and
+level-set reinitialization equation \eqref{eq:ls_reinit} can be written as
+systems of ordinary differential equations (ODEs) of the form
+\begin{equation}
+  \od{\vct \psi} \tau = \vct F(\vct\psi,\tau),
+\end{equation}
+where $\vct\psi$ is a vector containing the discrete variables and $\vct F$
+contains the spatially discretized terms.  The explicit Euler step becomes
+\begin{equation}
+  \mathcal E(\vct\psi^n) = \vct\psi^n + \Delta\tau \vct F(\vct\psi^n,\tau^n).
+\end{equation}
+In this thesis, these equations are solved with the third-order four-stage
+SSP-RK method \eqref{eq:ssprk34}.  The four-stage method is used because it is
+more accurate than the three-stage method.  We wanted to make sure that the
+error is mainly dominated by the spatial discretization.
+
+The semi-discretized Navier-Stokes equations \eqref{eq:navier-stokes-1} and
+\eqref{eq:navier-stokes-2} are solved together with the level-set advection
+equation \eqref{eq:ls_adeq} with the third-order three-stage SSP-RK method
+\eqref{eq:ssprk33}.  Here an explicit Euler step $\mathcal E(\vct
+u^n,\varphi^n)$ consists of the following steps:
+\begin{enumerate}
+  \item Calculate the curvature and the normal vectors from $\varphi^n$ with
+    one of the methods described in \cref{sec:curvature}.
+  \item Calculate the intermediate velocity field, either $\vct w$
+    \eqref{eq:continuousRightHandVector} or $\vct u^\star$ \eqref{eq:ustar}.
+  \item Solve the Poisson equation \eqref{eq:PoissonDP1} or
+    \eqref{eq:PoissonChorin} for the pressure as described in
+    \cref{sec:pressure-poisson}.
+  \item Correct the velocity field with either \eqref{eq:dp1-update} or
+    \eqref{eq:velcorrection}.
+  \item Advect the level-set function $\varphi^n$ with \eqref{eq:ls_adeq}.
+\end{enumerate}
+
+\section{Time step restriction}
+\label{sec:deltaT}
+We employ the Courant-Friedrich-Lewy~(CFL) condition to allow adaptive time
+stepping and to enforce stability.  The CFL condition that is used in this
+thesis is
+\begin{equation}
+  \Delta t = \frac{C}{\frac{C_c + C_v} 2
+             + \sqrt{(C_c + C_v)^2 + 4C_g^2 + 4C_s^2}},
+\end{equation}
+where the CFL restriction $C<1$, and $C_c$, $C_v$, $C_s$, and $C_g$ represent
+the contributions from the convective term, the viscous stresses, the surface
+tension, and the gravity, respectively,
+\begin{align}
+  C_c &=  \frac{\max_{i,j}|u_{i,j}|}{\Delta x}
+        + \frac{\max_{i,j}|v_{i,j}|}{\Delta y}, \\
+  C_v &= 2\max\left(\frac{\mu_1}{\rho_1},\frac{\mu_2}{\rho_2}\right)
+         \left(\frac{1}{\Delta x^2} + \frac{1}{\Delta y^2}\right), \\
+  C_s &= \sqrt{\frac{\sigma\max_{i,j}|\kappa_{i,j}|}
+                    {\max(\rho_1,\rho_2)\min(\Delta x^2,\Delta y^2)}}, \\
+  C_g &= \sqrt{\frac{|g_x|}{\Delta x} + \frac{|g_y|}{\Delta y}}.
+\end{align}
+This CFL condition is discussed in more detail by~\citet{Lervag08}, and it is
+based on the condition by \citet{Kang00}.
+
+\section{Axisymmetry}
+For axisymmetric flow, the governing equations \eqref{eq:ns1} and
+\eqref{eq:ns2} become
+\begin{equation}
+  \frac 1 r \pd{} r\left(r u\right) + \pd v z = 0,
+\end{equation}
+\begin{multline}
+  \rho\left(\pdt u + u\pd u r + v\pd u z\right) = -\pd p r \\
+    + \mu\left(\frac 1 r \pd{} r\left(r \pd u r\right)
+          + \pdd u z - \frac u {r^2}\right) + \rho f_r + {f_s}_r,
+\end{multline}
+and
+\begin{multline}
+  \rho\left(\pdt v + u\pd v r + v\pd v z\right) = -\pd p z \\
+    + \mu\left(\frac 1 r \pd{} r\left(r \pd v r\right)
+      + \pdd v z\right) + \rho f_z + {f_s}_z.
+\end{multline}
+Here $u$ and $v$ are the radial and axial velocity components, $f_r$ and $f_z$
+are the radial and axial body-force components, and ${f_s}_r$ and ${f_s}_z$ are
+the radial and axial components of the singular surface force, respectively.
+The equations are solved as explained in the previous sections.
+
+\section{Discretization of the curvature and the normal vector}
+\label{sec:curvature}
+As stated in \cref{sec:level-set}, the normal vector \eqref{eq:norm} and the
+curvature \eqref{eq:curv} can be calculated from the level-set function as
+\begin{align*}
+  \vct n &= \frac{\grad\varphi}{|\grad\varphi|}, \\
+  \kappa &= \div\left(\frac{\grad\varphi}{|\grad\varphi|}\right).
+\end{align*}
+They are typically discretized with the standard second-order
+central-difference scheme, cf.\ \cite{Kang00,Sethian03,Xu06}.  The normal
+vector is calculated at the cell edges, and the curvature is calculated at the
+grid nodes.  The curvature is then interpolated to the interface where needed
+with linear interpolation, for instance with
+\begin{equation}
+  \kappa_\Gamma = \frac{|\varphi_{i,j}|\kappa_{i+1,j}
+  + |\varphi_{i+1,k}|\kappa_{i,j}}{|\varphi_{i,j}| + |\varphi_{i+1,j}|}.
+  \label{eq:curvature-gamma}
+\end{equation}
+
+If the level-set method is used to capture non-trivial geometries, then it will
+contain kink regions, that is, areas where the gradient of the level-set
+function is discontinuous.  \Cref{fig:level-set-function} shows a simple
+example of such a kink region for a level-set function in a one-dimensional
+domain that captures two interfaces, one on each side of $x_i$.  The kink at
+$x_i$ may lead to large errors both for the curvature and the normal vector if
+one is not careful.  Errors in the curvature lead to errors in the surface
+tension force and in the pressure, which in turn lead to errors in the
+interface evolution and in the two-phase flow.  Errors in the normal vector
+affect both the calculation of the viscous jump condition and the advection of
+the interface.  If the level-set method is used to study for example
+coalescence and breakup of drops, these errors may severely affect the
+simulations.

+
+This problem was to our knowledge first described by \citet{Smereka03}, who
+increase the numerical smoothing in the curvature discretization to lessen the
+effect.  Several non-smearing approaches have subsequently been developed.
+\citet{Macklin05} used the level-set method to study tumor growth, and they
+present a one-sided direction-difference scheme for the discretization of the
+normal vector and the curvature.  Later, \citet{Macklin06} presented an
+improved geometry-aware curvature discretization, where the curvature is
+calculated based on a local least-squares parametrisation of the interface.
+
+A different approach to avoid the kinks was presented by \citet{Salac08}.  They
+used a level-set extraction technique, where an extraction algorithm was used
+to reconstruct separate level-set functions for each distinct \emph{body}.  The
+term \emph{body} is used here to denote a subset of a given phase or fluid.
+For example, in the case of two drops of water colliding in air, the water
+drops would make two distinct bodies.  One can also avoid the extraction
+algorithm altogether by use of multiple marker functions for different bodies,
+see for instance \cite{Coyajee09,Kwakkel12}.  Note, however, that the latter
+approach means that the different bodies will not coalesce unless explicit
+action is made, cf.~\cite{Kwakkel13}.  Also, both of the approaches mentioned
+here fails to handle the problem of kinks from a single body.  That is, there
+may still be kink areas due to deformed bodies, for instance bodies with thin
+filaments or tails, or bodies shaped like horse shoes.
+
+In the following, we first present the direction-difference
+scheme~\cite{Macklin05}.  We then describe the curve-fitting discretization
+method and the local level-set extraction method.
+
+\subsection{Direction-difference scheme}
+\label{sec:dds}
+The direction-difference scheme (DDS) was introduced by \citet{Macklin05}.  It
+uses a quality function to ensure that the difference stencils never cross any
+kink regions.  The DDS is used in Papers A--C to calculate the normal vectors.
+However, in Paper C it is shown that the DDS does not always yield an accurate
+approximation of the normal vector.
+
+The basic strategy is to use a combination of central differences and one-sided
+differences based on the values of a quality function,
+\begin{equation}
+  Q(\vct x) = \left| 1 - |\grad\varphi(\vct x)|\right|.
+  \label{eq:quality}
+\end{equation}
+The quality function is approximated with central differences, and is used to
+detect the areas where the level-set function differs from the signed-distance
+function.  In the following, let $Q_{i,j} \equiv Q(\vct x_{i,j})$ and define
+a parameter $\eta>0$.  This threshold parameter is tuned such that the quality
+function will detect all the kinks.
+
+The quality function is used to define a direction function,
+\begin{equation}
+  \vct D(\vct x_{i,j}) = (D_x(\vct x_{i,j}), D_y(\vct x_{i,j})),
+\end{equation}
+where
+\begin{equation}
+  D_x(\vct x_{i,j}) = \begin{cases}
+    -1 & \text{if $Q_{i-1,j}<\eta$ and $Q_{i+1,j}\geq\eta$,} \\
+     1 & \text{if $Q_{i-1,j}\geq\eta$ and $Q_{i+1,j}<\eta$,} \\
+     0 & \text{if $Q_{i-1,j}<\eta$ and $Q_{i,j}<\eta$ and $Q_{i+1,j}<\eta$,} \\
+     0 & \text{if $Q_{i-1,j}\geq\eta$ and $Q_{i,j}\geq\eta$ and
+         $Q_{i+1,j}\geq\eta$,} \\
+     4 & \text{otherwise.}
+  \end{cases}
+  \label{eq:dirfunc}
+\end{equation}
+$D_y(\vct x_{i,j})$ is defined in a similar manner.  If $D_x(\vct x_{i,j})
++ D_y(\vct x_{i,j}) > 2$, then $\vct D(\vct x_{i,j})$ is chosen as the vector
+normal to $\grad\varphi(\vct x_{i,j})$.  It is normalized, and the sign is
+chosen such that it points in the direction of the best quality.  See
+\cite{Macklin05} for more details.
+
+The DDS is then defined as
+\begin{equation}
+  \partial_x f_{i,j} = \begin{cases}
+    \frac{f_{i,j} - f_{i-1,j}}{\Delta x}    & \text{if $D_x(x_i,y_j) = -1$,} \\
+    \frac{f_{i+1,j} - f_{i,j}}{\Delta x}    & \text{if $D_x(x_i,y_j) =  1$,} \\
+    \frac{f_{i+1,j} - f_{i-1,j}}{2\Delta x} & \text{if $D_x(x_i,y_j) =  0$,}
+  \end{cases}
+  \label{eq:Ddifference}
+\end{equation}
+and similarly for $\partial_y f_{i,j}$, where $f_{i,j}$ is a piecewise smooth
+function.  The DDS is equivalent to using central differences in smooth areas
+and one-sided differences in areas close to the kinks.
+
+\subsection{Curve-fitting discretization method}
+\label{sec:curvature-curve-fitting}
+The curve-fitting discretization method (CFDM) was first presented
+in~\cite{Lervag11} and is based on the method by \citet{Macklin06}.  The main
+idea is to identify kink regions with the quality function \eqref{eq:quality},
+and to use a curve parametrisation of the closest interface to calculate the
+curvature in regions where the quality function is larger than the threshold
+parameter, $\eta$.
+
+The CFDM applied to the curvature or the normal vector at the grid point $\vct
+x_{i,j}$ can be summarized as follows.  See also \cref{fig:cfdm}, which shows
+an example of the CFDM used at $\vct x_{i,j}$.
+\begin{enumerate}
+  \item If the quality of the level-set function in the neighbourhood of $\vct
+    x_{i,j}$ is good, that is
+    \[
+      Q(\vct{x}_{n,m}) \le \eta \; \forall (n,m) \in [i-1,i+1]\times[j-1,j+1],
+    \]
+    then we use a standard discretization.  Otherwise continue to the next
+    step.
+  \item Locate the closest interface, $\Gamma$.
+  \item Find a set of points on the located interface, $\vct x_1, \dots, \vct
+    x_n \in \Gamma$.
+  \item Create a parametrisation $\vct \gamma(s)$ of the points $\vct x_1,
+    \dots, \vct x_n$.
+  \item Use the parametrisation $\vct \gamma(s)$ to calculate a local level-set
+    function.
+  \item Use a standard discretization of the local level-set function to
+    calculate the curvature or the normal vector.
+\end{enumerate}

+\subsection{Local level-set extraction method}
+\label{sec:lolex}
+The local level-set extraction (LOLEX) method is based on the method presented
+by \citet{Salac08}, here called the SLM.  It was found that the latter method
+was insufficient, because it did not treat all the kink problems.  The LOLEX
+method is therefore a further development of the SLM, in that it handles the
+kink regions in a more general manner.
+
+The LOLEX method applied to the curvature or the normal vector at a grid point
+$\vct x_{i,j}$ is summarized by the following algorithm.  The algorithm is
+presented with 2D notation for clarity, and extends easily to 3D.  See also
+\cref{fig:lolex}, which gives a simple example of the procedure.
+\begin{enumerate}
+  \item If the quality in the neighbourhood of $\vct x_{i,j}$ is good, that is
+    \[
+      Q(\vct{x}_{n,m}) \le \eta \; \forall (n,m) \in [i-1,i+1]\times[j-1,j+1],
+    \]
+    then we use a standard discretization.  Otherwise continue to the next
+    step.
+  \item Copy a small, local square centred around $\vct x_{i,j}$ from the
+    level-set function $\varphi$ into a local array $\varphi_\text{loc}$.
+  \item Identify and enumerate all the \emph{bodies} in the local array
+    $\varphi_\text{loc}$.  A \emph{body} is here defined as a set of
+    neighbouring points where $\varphi_\text{loc}<0$, see \cref{fig:lolex}.
+    There will be $n\geq 0$ bodies in any given $\varphi_\text{loc}$ array.
+  \item If no body is identified, that is, if $n=0$, then use a standard
+    discretization with the global level-set function $\varphi$.  Otherwise
+    continue to the next step.
+  \item For each body $n$, extract the relevant parts of $\varphi_\text{loc}$
+    into an array $\varphi_\text{loc}^n$.  If necessary, extrapolate values to
+    ghost cells.
+  \item For each body, $n$, reinitialize $\varphi_\text{loc}^n$.
+  \item At this step, all the bodies in the local grid have their own
+    local level-set functions that have been reinitialized to proper
+    signed-distance functions.  Due to the separation of the bodies, there
+    are no longer any kinks.
+  \item Use the standard discretization of the curvature and the normal
+    vector at the local level-set function that represents the body that is
+    closest to $\vct x_{i,j}$.

+\chapter{The diffuse-domain approach}
+\label{chap:diffuse-domain}
+In the previous chapters, we have considered the modelling of two-phase flows,
+and in particular methods for calculating the curvature and normal vector with
+the level-set method in a reliable manner.  In this chapter, we consider
+a different problem of a more general nature:  How to solve partial
+differential equations (PDEs) in complex domains.  In particular, we consider
+an extension of a diffuse-domain method (DDM) by a high-order correction term
+that gives increased accuracy with respect to interface-width refinements.
+
+We begin with a short introduction to the diffuse-domain approach.  We then
+outline how it can be used to derive a DDM for the steady reaction-diffusion
+equation with Neumann boundary conditions.  Next, we continue with a brief
+introduction to the method of matched asymptotic expansions.  Finally, we
+introduce the high-order correction term derived in Paper~E and show that the
+resulting DDM converge with second order in the diffuse-interface width to the
+original problem.  The analysis also shows that the correction term is not
+necessary for second-order convergence.
+
+\section{Introduction}
+There exist several methods for solving PDEs in complex domains.  Most of them
+have in common that they require tools or methods that are not frequently
+available in standard finite-element or finite-difference software packages.
+Examples of such methods include the immersed-interface method
+\cite{LeVeque94}, the matched interface and boundary method \cite{Zhou06}, the
+extended and composite finite-element method \cite{Dolbow09}, embedded boundary
+methods \cite{Johansen98}, cut-cell methods \cite{Ji06}, and ghost-fluid
+methods \cite{Fedkiw99}.  A different approach, known as the fictitious domain
+method~\cite{Glowinski94,Glowinski96} or the domain imbedding
+method~\cite{Buzbee71}, either augments the original system with equations for
+Lagrange multipliers to enforce the boundary conditions, or use the penalty
+method to enforce the boundary conditions weakly.  For a more complete list of
+references, see Paper~E.
+
+The DDM is an alternative method for solving PDEs in complex domains.  The main
+idea is to use an implicit representation of the boundary, where the sharp
+boundary is replaced by a diffuse layer.  The PDEs are then reformulated on
+a larger, regular domain, and the boundary conditions are incorporated via
+source terms in the diffuse layer.  When the thickness of the diffuse layer is
+reduced, these source terms tend towards singular source terms.  The resulting
+PDEs can then be solved with the use of standard tools and methods.
+
+The diffuse-domain approach was first introduced by \citet{Kockelkoren03} to
+study diffusion inside a cell with homogeneous Neumann boundary conditions at
+the cell boundary.  It was later used by \citet{Li09} to develop a DDM for
+solving PDEs in complex evolving domains with Dirichlet, Neumann and Robin
+boundary conditions, which is hereafter called the DDM1.  The DDM1 has been
+used by \citet{Teigen09-b}, who modelled bulk-surface coupling of material
+quantities on a deformable interface.  It was also used by \citet{Aland10} to
+simulate incompressible two-phase flows in complex domains in 2D and 3D, and by
+\citet{Teigen11} to study two-phase flows with soluble surfactants.
+
+An analysis of the error behaviour of the diffuse-domain approach was done by
+\citet{Franz12} for a diffuse-domain approximation of an elliptic problem with
+Dirichlet boundary conditions.  They considered the infinity norm of the
+difference of the approximated solution and the exact solution, and their
+analysis shows that the approximation quality is of order one in the interface
+width.
+
+In Paper~E, we present the DDM2, which is an extension of the DDM1 by
+a high-order correction term.  The DDM2 is derived for elliptic problems with
+Neumann and Robin boundary conditions, and it is shown to be asymptotically
+second-order accurate in the interface width.  However, the analysis in Paper~E
+is somewhat lacking in that it assumes that the DDM1 is only first-order
+accurate.  In the following sections, we extend the analysis of Paper~E and
+show that the DDM1 is also second-order accurate.  The analysis is shown for
+the steady reaction-diffusion equation with Neumann boundary conditions, but
+the same technique also applies for the corresponding Robin problem.
+
+\section{The DDM for a Neumann problem}
+Consider the steady reaction-diffusion equation with Neumann boundary
+conditions,
+\begin{equation}
+  \begin{alignedat}{2}
+    \lapl u - u  &= f        & \txin D, \\
+    \ndot\grad u &= g \qquad & \txon \partial D,
+  \end{alignedat}
+  \label{eq:ddan}
+\end{equation}
+where $f$ and $g$ are given.  Let $\chi_D$ be the characteristic function of
+$D$,
+\begin{equation}
+  \chi_D = \begin{cases}
+    1 & \text{if $x\in D$,} \\
+    0 & \text{if $x\notin D$.}
+  \end{cases}
+\end{equation}
+The main idea with the diffuse-domain approach is to extend the original
+equation \eqref{eq:ddan} into a larger and regular domain $\Omega\supset D$, as
+depicted in \cref{fig:ddadomain}.  The extension can be written as
+\begin{equation}
+  \div(\chi_D\grad u) - \chi_D u + \text{BC} = \chi_D f,
+  \label{eq:ddm}
+\end{equation}
+where BC is a singular source term that represents the physical boundary
+condition on $\partial\Omega$.

+  \end{tikzpicture}
+  \caption{A regular domain $\Omega$ that contains a complex domain $D$.}
+  \label{fig:ddadomain}
+\end{figure}
+
+The characteristic function is typically approximated by the phase-field
+function,
+\begin{equation}
+  \chi_D \simeq \phi(\vct x,t) = \frac{1}{2} \left( 1
+  - \tanh \left( \frac{3r(\vct x,t)}{\epsilon} \right) \right),
+  \label{eq:characteristic}
+\end{equation}
+where $\epsilon$ is the interface width and $r(\vct x,t)$ is the
+signed-distance function with respect to the boundary $\partial D$, which is
+taken to be negative inside $D$.
+
+The main difficulty with the diffuse-domain approach is the derivation of
+approximations for the boundary condition term BC.  \citet{Li09} give four
+approximations that are shown to converge asymptotically with first order in
+$\epsilon$ to the original equation when $\epsilon$ is decreased.  In the
+following we consider the approximation
+\begin{equation}
+  \text{BC} \simeq |\grad\phi| g.
+  \label{eq:bc1}
+\end{equation}
+If we combine the above approximations \eqref{eq:characteristic} and
+\eqref{eq:bc1}, we get a DDM1 equation for \eqref{eq:ddan},
+\begin{equation}
+  \div\left(\phi\grad u\right) - \phi u +  |\grad\phi| g = \phi f.
+  \label{eq:ddm1}
+\end{equation}
+
+\section{The method of matched asymptotic expansions}
+The following is a brief introduction to the method of matched asymptotic
+expansions, which is used to show that a given diffuse-domain approximation
+converges to the original problem when the interface width is decreased.  More
+details can be found in Paper~E and in \cite{Pego88}.
+
+Let $u$ be some diffuse-domain variable.  The asymptotic convergence of a given
+diffuse-domain approximation can be shown through expansions of the
+diffuse-domain variables in powers of the interface thickness $\epsilon$ in
+regions close to and far from the interface.  For example, the expansions of
+$u$ are
+\begin{align}
+  u(\vct x)        &= \sum_{k=0}^\infty \epsilon^k      u^{(k)}(\vct x), \\
+  \hat u(z,\vct s) &= \sum_{k=0}^\infty \epsilon^k \hat u^{(k)}(z,\vct s),
+\end{align}
+where $u(\vct x)$ and $\hat u(\vct s,z)$ denote the outer and inner expansions,
+respectively.  Here $z$ is a stretched variable,
+\begin{equation}
+  z = \frac{r(\vct x)}{\epsilon},
+\end{equation}
+where $r$ is the signed distance from the point $\vct x$ to $\partial D$ and is
+taken to be negative inside $D$.  Further, $z$ and $\vct s$ form a local
+coordinate system such that
+\begin{equation}
+  \vct x(\vct s,z) = \vct X(\vct s) + \epsilon z\vct n(\vct s),
+\end{equation}
+where $\vct X(\vct s)$ is a parametrisation of the interface, $\vct n(\vct s)$
+is the interface normal vector, and $z$ is a stretched variable.
+
+When the inner and outer expansions are found, they are matched in a region
+where both solutions are valid and where $\epsilon z = \bigo 1$, see
+\cref{fig:regions}.  The outer solution is then evaluated in the inner
+coordinates, which leads to a set of matching conditions that must hold when
+$\epsilon\to 0$.  If we consider $\epsilon$ to be fixed and let $z \to
+\pm\infty$, we get the following asymptotic matching conditions:
+\begin{equation}
+  \label{eq:match1}
+  \zlimpm \hat u^{(0)}(z,\vct s) = u^{(0)}(\vct s),
+\end{equation}
+and as $z \to \pm\infty$,
+\begin{align}
+  \label{eq:match2}
+  \hat u^{(1)}(z,\vct s) &= u^{(1)}(\vct s)
+    + z\ndot\grad u^{(0)}(\vct s) + \smallo 1, \\
+  \begin{split}
+    \hat u^{(2)}(z,\vct s) &= u^{(2)}(\vct s)
+      + z\ndot\grad u^{(1)}(\vct s) \\
+      &\quad + \frac{z^2}{2} (\ndot\grad)\grad u^{(0)}(\vct s)\cdot\vct n
+      + \smallo 1.
+    \label{eq:match3}

+
+We remark that the inner expansion is used to obtain the boundary condition on
+$\partial D$, and that the outer solution is used to obtain the sharp-interface
+equation inside the physical domain $D$.
+
+To show that a given DDM approximation converges with second order, one must
+show that the order-one term of the outer solution of the DDM equation is zero
+in $D$.  As an example, we consider the outer solution of the DDM1 equation
+\eqref{eq:ddm1}, which is
+\begin{equation}
+  \begin{split}
+    \lapl u^{(0)} - u^{(0)} &= f, \\
+    \lapl u^{(1)} - u^{(1)} &= 0, \\
+    \lapl u^{(k)} - u^{(k)} &= 0,\qquad k = 2,3,\dots.
+  \end{split}
+  \label{eq:ddm_outer}
+\end{equation}
+For the solution to be asymptotically second order, that is $u = u^{(0)}
++ \bigo{\epsilon^2}$, we must have that $u^{(0)}$ satisfies the original
+problem \eqref{eq:ddan} and that $u^{(1)}=0$.  Thus the inner expansion must
+yield a boundary condition for $u^{(1)}$ to enforce $u^{(1)}=0$.
+
+\section{Asymptotic analysis of the DDM1 and the DDM2}
+\label{sec:DDM2}
+In Paper~E we present the DDM2, which extends the DDM1 \eqref{eq:ddm1} with
+a high-order correction term,
+\begin{equation}
+  \div\left(\phi\grad u\right) - \phi u +  |\grad\phi| g
+    + r|\grad\phi|\left(f - \kappa  g - \lapls u + u\right) = \phi f.
+  \label{eq:ddm2}
+\end{equation}
+Here $r|\grad\phi|\left(f - \kappa  g - \lapls u + u\right)$ is the
+correction term, $\kappa$ is the curvature of the boundary $\partial D$, and
+$\lapls u$ is the surface Laplacian of $u$, which can be defined as
+\begin{equation}
+  \lapls u \equiv
+  \left( I - \vct n\otimes\vct n \right)
+        \div \left( I - \vct n\otimes\vct n \right)\grad u,
+\end{equation}
+where $I$ is the identity matrix and $\vct n$ is the normal vector.  The
+curvature can be calculated from the phase-field function
+\eqref{eq:characteristic} as
+\begin{equation}
+  \kappa = -\div\frac{\grad\phi}{|\grad\phi|}.
+\end{equation}
+
+In the following, we use the method of matched asymptotic expansions to show
+that the DDM1 \eqref{eq:ddm1} and the DDM2 \eqref{eq:ddm2} are both
+second-order approximations of \eqref{eq:ddan} in $\epsilon$.  First, it is
+easy to see that the outer expansions of both approximations are given by
+\eqref{eq:ddm_outer}.
+
+Next, we consider the inner expansion of the DDM2 \eqref{eq:ddm2}, which is
+\begin{multline}
+  \frac{1}{\epsilon^2}\left(\phi\hat u_z\right)_z
+  + \frac \kappa \epsilon \phi\hat u_z
+  + \phi\lapls \hat u
+  - \phi\hat u \\
+  - \frac 1 \epsilon \phi_z g
+  - z\phi_z\left(\hat u + \hat f - \kappa g - \lapls\hat u\right)
+  = \phi \hat f.
+  \label{eq:ddm_inner}
+\end{multline}
+We expand $\hat u(z,\vct s)$ in powers of $\epsilon$ and collect the lowest
+order terms,
+\begin{equation}
+  \left(\phi\hat u_z^{(0)}\right)_z = 0.
+\end{equation}
+If we integrate over all $z$, we get that $\hat u_z^{(0)} = 0$.  The next order
+terms of~\eqref{eq:ddm_inner} then give
+\begin{equation}
+  \left(\phi\hat u_z^{(1)}\right)_z = \phi_z g,
+\end{equation}
+and again we integrate, which gives that
+\begin{equation}
+  \phi\hat u_z^{(1)} = \phi g + C
+  \label{eq:uz1}
+\end{equation}
+where the constant $C$ must be zero, since $\lim_{z\to\infty}\phi(z) = 0$.  Now
+consider the limit $z\to-\infty$ and use the matching condition
+\eqref{eq:match2} to get
+\begin{equation}
+  \ndot\grad u^{(0)} = g.
+\end{equation}
+Thus $u^{(0)}$ satisfies the original problem at least to first order in
+$\epsilon$.  This shows that both DDM1 and DDM2 are first-order approximations
+of the sharp-interface problem.
+
+To obtain the result for the next order, we need to apply the derivative of
+the matching condition \eqref{eq:match3},
+\begin{equation}
+  \hat u_z^{(2)} = \ndot\grad u^{(1)}
+      + z (\ndot\grad)\grad u^{(0)}\cdot\vct n.
+  \label{eq:match3_z}
+\end{equation}
+Further, we use that $u^{(0)}$ satisfies
+\begin{equation}
+  \lapl u^{(0)} - u^{(0)} = f^{(0)},
+\end{equation}
+and that the Laplacian may be decomposed as
+\begin{equation}
+  \lapl u = (\ndot\grad)\grad u\cdot\vct n + \kappa\ndot\grad u + \lapls u,
+\end{equation}
+to get
+\begin{equation}
+  (\ndot\grad)\grad u^{(0)}\cdot\vct n
+    = u^{(0)} + f^{(0)} - \kappa g - \lapls u^{(0)}.
+  \label{eq:ngradun}
+\end{equation}
+Now insert \eqref{eq:ngradun} into \eqref{eq:match3_z} and use the matching
+condition \eqref{eq:match1} to obtain a modified matching condition,
+\begin{equation}
+  \hat u_z^{(2)} - z\left(\hat u^{(0)} + \hat f^{(0)}
+        - \kappa g - \lapls \hat u^{(0)}\right)
+  = \ndot\grad u^{(1)}.
+  \label{eq:match3_z2}
+\end{equation}
+
+We are now ready to consider the zeroth order terms,
+\begin{multline}
+  \label{eq:o1}
+  \left(\phi\hat u^{(2)}_z\right)_z
+  + \phi\kappa\hat u_z^{(1)}
+  + \phi\lapls \hat u^{(0)}
+  - \phi\hat u^{(0)} \\
+  - z\phi_z\left(\hat u^{(0)}
+      + \hat f^{(0)} - \kappa g - \lapls\hat u^{(0)}\right)
+  = \phi \hat f^{(0)}.
+\end{multline}
+The modified matching condition \eqref{eq:match3_z2} motivates that we subtract
+and add the term
+\[
+  \bigg(z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\bigg)_z
+\]
+to \eqref{eq:o1}, which gives
+\begin{multline}
+  \bigg(\phi\hat u_z^{(2)}
+    - z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\bigg)_z \\
+  + \bigg(z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\bigg)_z \\
+  + \phi\kappa\hat u_z^{(1)}
+  + \phi\lapls \hat u^{(0)}
+  - \phi\hat u^{(0)} \\
+  - z\phi_z\left(\hat u^{(0)}
+      + \hat f^{(0)} - \kappa g - \lapls\hat u^{(0)}\right)
+  = \phi \hat f^{(0)}.
+\end{multline}
+We expand the terms and use \eqref{eq:uz1},
+\begin{multline}
+  \bigg(\phi\hat u_z^{(2)}
+    - z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\bigg)_z \\
+  + \cancel{\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)} \\
+  + z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)_z \\
+  + \cancel{\phi\kappa g
+  + \phi\lapls \hat u^{(0)}
+  - \phi\hat u^{(0)}}
+  = \cancel{\phi \hat f^{(0)}},
+  \label{eq:o2}
+\end{multline}
+or
+\begin{multline}
+  \bigg(\phi\hat u_z^{(2)}
+    - z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\bigg)_z \\
+  + z\phi\left(\cancel{\hat u_z^{(0)}} + \hat f_z^{(0)}
+      - \cancel{(\kappa g)_z}
+      - \cancel{\lapls \hat u_z^{(0)}}\right) = 0.
+\end{multline}
+If we assume that $\hat f_z^{(0)}$, we get
+\begin{equation}
+  \bigg(\phi\hat u_z^{(2)}
+    - z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\bigg)_z = 0.
+  \label{eq:o3}
+\end{equation}
+Finally, we integrate the left-hand side and take the limit,
+\begin{align}
+  \nonumber
+  \eint{\bigg(\phi\hat u_z^{(2)}
+    &- z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+     - \lapls \hat u^{(0)}\right)\bigg)_z} \\
+  \nonumber
+  &= \ejmp{\phi\hat u_z^{(2)}
+    - z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)} \\
+  \nonumber
+  &= -\zlimm{\left(\hat u_z^{(2)}
+    - z\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\right)} \\
+  &= -\ndot\grad u^{(1)},
+\end{align}
+thus
+\begin{equation}
+  \ndot\grad u^{(1)} = 0.
+  \label{eq:ngradu1}
+\end{equation}
+Combined with \eqref{eq:ddm_outer}, this shows that $u^{(1)}=0$, and so DDM2
+converges asymptotically with second order to the original problem.
+
+The analysis above also holds for DDM1, except instead of \eqref{eq:o3} we get
+\begin{multline}
+  \bigg(\phi\hat u_z^{(2)}
+    - z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\bigg)_z \\
+  = - z\phi_z \left(\hat u^{(0)} + \hat
+        f^{(0)} - \kappa g - \lapls \hat u^{(0)}\right)
+  = - z\phi_z D,
+  \label{eq:o4}
+\end{multline}
+where $D$ is independent of $z$.  Now we use that
+\begin{equation}
+  \phi_z = -(3 \sech^2 3z)/2,
+\end{equation}
+which follows from the definition of the phase-field function
+\eqref{eq:characteristic}.  We integrate the right-hand side, which gives
+\begin{equation}
+  D\eint{z\phi_z} = -D\frac 3 2\eint{z\sech^2 3z} = 0.
+\end{equation}
+Thus DDM1 is also second order in $\epsilon$.
+
+The difference between the DDM1 and the DDM2 is therefore that the correction
+term with the DDM2 directly cancels the term on the right-hand side in
+\eqref{eq:o4}.  This should give an increase of accuracy, but the convergence
+order remains the same.
+
+The analysis for the corresponding Robin problem is essentially the same as the
+above.  In Paper~E, the DDM1 and DDM2 are compared for several elliptic
+problems with both Neumann and Robin boundary conditions.  The results of
+Paper~E show that the correction term in the DDM2 leads to an increase of
+accuracy and that both DDM1 and DDM2 converge with second-order accuracy.
+
+\section{Summary}
+In this chapter, we have given a brief introduction to the diffuse-domain
+method (DDM).  We considered a steady reaction-diffusion equation with Neumann
+boundary conditions \eqref{eq:ddan} and two DDM approximations:  DDM1
+\eqref{eq:ddm1} and DDM2 \eqref{eq:ddm2}.  The DDM2 is an extension of DDM1 by
+a high-order correction term, and was first derived in Paper~E.
+
+Next, we gave an outline of the method of matched asymptotic expansions, and we
+used it to show that both the DDM1 and the DDM2 converged asymptotically with
+second order in the diffuse-interface width to the original equation
+\eqref{eq:ddan}.  The analysis shows that the correction term in the DDM2 leads
+to a cancellation in the asymptotic expansions.  By doing the integration, we
+see that this cancellation is not necessary for obtaining the second order
+convergence.

+\section[Paper A]{Paper A:  Calculation of interface curvature with the
+  level-set method}
+Karl Yngve Lervåg.  Published in \emph{MekIT'11 - 6th National Conference on
+  Computational Mechanics, Trondheim}, 2011.  ISBN: 978-82-519-2798-7.
+
+In this paper I address a problem with the calculation of the interface
+curvature with the level-set method, cf.\ \cref{sec:curvature}.  The curvature
+can be calculated from the level-set function, $\phi$, as
+\begin{equation}
+  \kappa = \div\vct n = \div\frac{\grad\phi}{|\grad\phi|}.
+\end{equation}
+It is typically discretized by standard methods such as the second-order
+central-difference scheme (CD-2), and interpolated to the interface where
+needed \cite{Osher88,Kang00,Osher03}.  However, the level-set function as
+a signed-distance function will tend to have kinks where its gradient is
+discontinuous.  The standard methods may lead to large errors in the curvature
+close to these regions, which in turn may lead to errors in the surface tension
+force.
+
+The main contribution of this paper is a new curve-fitting discretization
+method (CFDM) for the curvature (see \cref{sec:curvature-curve-fitting}).  The
+method is based on the approach developed by \citet{Macklin06}.  It differs in
+that it uses a cubic Hermite spline parametrisation of the interface, and that
+the curvature values are calculated on the grid and then interpolated to the
+interface as opposed to using a localised grid centred at the interface as in
+\cite{Macklin06}.

+    close to two interfaces.}

+\end{figure}
+
+The CFDM is tested and compared with the CD-2 for two test cases, and it is
+shown to yield better results in both cases.  \Cref{fig:A1} shows one of these
+results, where the calculated curvature values are compared.  In the example,
+a cylindrical drop impacts on a liquid film.  The figure shows that the CD-2
+leads to large errors in the curvature calculations in the kink regions, that
+is, the red and dark blue regions in \cref{fig:A1a} near the liquid film.
+These errors are not present with the new method, cf.\ \cref{fig:A1b}.
+

+\section[Paper B]{Paper B:  Curvature calculations for the level-set method}
+Karl Yngve Lervåg and Åsmund Ervik.  Published in \emph{ENUMATH 2011}
+proceedings volume, Springer, 2013.  ISBN: 978-3642331336.
+
+This paper is a continuation of Paper A.  The main contribution in this paper
+is a comparison of different methods for calculating the curvature in a robust
+manner with the level-set method in the kink regions.  In particular, the
+CFDM\footnote{The method is called LM in the paper.  Here CFDM is used, in
+  order to be consistent with the rest of the thesis.} that was presented in
+Paper A is compared with Macklin and Lowengrub's method (MLM)~\cite{Macklin06}.
+In addition, the method is compared with the second-order central-difference
+scheme (CD-2) and the more recent method presented by \citet{Salac08}, here
+called Salac and Lu's method (SLM).
+
+The main result in the paper is shown in \cref{fig:B1}, which shows
+a comparison of the methods for a case where two drops collide in a 2D shear
+flow.  In particular, it shows snapshots of the evolution of the interfaces and
+the curvature at times $t=\SI{2.30}{s}$, $t=\SI{2.75}{s}$, and
+$t=\SI{3.10}{s}$.  The results show that all of the improved methods, that is
+MLM, CFDM, and SLM, handle the kink region in a more reliable manner than CD-2.
+The reason that the result with MLM differs from those with CFDM and SLM might
+be that it uses a localised grid centred at the interface to calculate the
+curvature, which means that it does not need to use interpolation of the
+curvature from the grid to the interface.  Note that the difference is mainly
+that the MLM results in slightly earlier coalescence in the given case.

+\section[Paper C]{Paper C:  Calculation of the interface curvature and normal
+  vector with the level-set method}
+Karl Yngve Lervåg, Bernhard Müller, and Svend Tollak Munkejord.  Published in
+Computers and Fluids, volume 84 (2013), 218--230.
+
+Paper A presented the curve-fitting discretization method (CFDM) for the
+calculation of the curvature with the level-set method.  The method was
+designed to be robust in the calculation of the curvature in kink regions, that
+is regions where the gradient of the level-set function is not smooth.  This
+paper presents the details of the CFDM and applies it to the calculation of
+both the curvature and the normal vector.
+
+In the paper we compare the CFDM with the second-order central-difference
+scheme (CD-2) for several test cases.  In the first case, we consider the
+curvature calculations for a nontrivial geometry that includes some kink
+regions.  This is a static test case with no flow, and the results show that
+the CD-2 leads to large errors for the curvature calculations in areas close to
+kink regions and that these errors are not present with the CFDM.
+
+In the following two cases, we consider the collision of two drops in a 2D
+shear flow and in an axisymmetric flow.  These cases show that the errors in
+the curvature calculations in the kink regions with the CD-2 lead to errors in
+the pressure that prevents coalescence.  These errors are prevented with the
+CFDM.  The curvature and the evolution of the interfaces for the axisymmetric
+case are shown in \cref{fig:C1,fig:C2}.  As in the earlier results of Papers
+A and B, the figures show that the errors in the curvature calculation with
+CD-2 prevent coalescence, in this case leading to a slower coalescence process.

+\section[Paper D]{Paper D:  A robust method for calculating interface curvature
+  and normal vectors using an extracted local level set}
+Åsmund Ervik, Karl Yngve Lervåg, and Svend Tollak Munkejord.  Submitted to
+Journal of Computational Physics, 2013.
+
+In this paper we present an alternative method for the calculation of the
+curvature and the normal vector of an interface with the level-set method in
+kink regions, hereafter called the local level-set extraction (LOLEX) method.
+The method is based on a method presented by \citet{Salac08} (SLM), who handle
+the kink region by extracting different bodies of a domain into separate
+level-set functions.  This procedure removes most of the kink regions, but it
+does not handle kink regions that are due to complex interfaces of single
+bodies.  Our method extends the SLM by making it local.  That is, we only
+consider the local area around the point for which we are calculating the
+curvature or the normal vector.  This leads to a method that is more generally
+applicable, as shown in \cref{fig:D1}.  The figure shows a comparison between
+the LOLEX method, the SLM, and the standard central differences (CD-2).  CD-2
+leads to curvature spikes at the kink regions, as explained in
+\cref{sec:curvature}.  The SLM gives a better result for the kink regions
+around the rightmost disc.  However, since the other two discs are connected to
+each other and to the film, they are considered to be the same body and are
+extracted into the same level-set function.  Several kink regions are therefore
+not removed.  Since the LOLEX method only considers the local area, as
+explained in \cref{sec:lolex}, it is able to handle all the kink regions in
+a robust manner.

+    negative and red is positive.}
+  \label{fig:D1}
+\end{figure}
+
+The LOLEX method has proven to be a good alternative to the CFDM presented in
+Paper A.  Its main advantages are that it does not rely on complex algorithms
+as used in the CFDM or by \citet{Macklin06}, and that the method easily extends
+to 3D as demonstrated in the paper in Section~4.4.
+
+In the previous papers A--C, we used the DP1 projection method by
+\citet{Hansen05}.  In this paper we instead used the more standard Chorin
+projection method.  These methods differ in that the DP1 assumes
+\begin{equation}
+  \div\left(\pdt{\vct u}\right) = 0.
+\end{equation}
+When compared with the Chorin method, this assumption becomes equivalent to
+assuming that $\div\vct u^{n} = 0$ in \eqref{eq:PoissonChorin}.  That is, the
+DP1 assumes that the initial velocity field is divergence free.  We have found
+that the DP1 works well in most cases, but that it is less robust than the
+Chorin method.  In particular, the Chorin method is not equally affected by
+errors in the curvature calculations in kink regions.  In other words, the
+difference between using a standard discretization and an improved
+discretization of the curvature is smaller with the Chorin method than with the
+DP1.
+
+The LOLEX method is used for several test cases and compared with CD-2.  The
+results indicate that even though we use the Chorin projection method, the
+LOLEX method outperforms CD-2 in all cases.  Further, the results agree well
+with experiments, except for time instants, as shown in \cref{fig:D2}.  The
+exact reason why the time instants do not match is not known, but one reason
+may be that the initial condition of the numerical simulation did not match the
+corresponding state of the experiment.

+    from~\cite{Zhao11}, Copyright (2011), with permission from Elsevier.}
+  \label{fig:D2}
+\end{figure}
+
+When we study the drop-film collision processes, an important consequence of
+the error in the curvature calculation is a loss of kinetic energy.  This can
+be seen in \cref{fig:D3}, which compares the LOLEX method with CD-2 at two
+different stages of the collision process.  The figure also compares two
+different frequencies of reinitialization of the level-set function:  Every
+7 time steps ((a) and (c)) and every single time step ((b) and (d)).  The
+figure shows that the error in the curvature calculation with CD-2 leads to
+a shorter neck, as seen in \cref{fig:D3}, (c) and (d).  The error is larger for
+the higher frequency of reinitialization.  The results indicate that CD-2 leads
+to a loss of kinetic energy during the collision process when compared with the
+LOLEX method.  The LOLEX method is not significantly affected by the amount of
+reinitialization, and the kink region does not affect the curvature
+calculation, cf.\ \cref{sec:lolex}.  Thus the pressure field is more sensible,
+as seen in \cref{fig:D3} (a) and (b).  Finally, we remark that some authors
+have noted \cite{Blanchette06} that the height of the neck and the dynamics of
+the capillary waves are important factors for the partial coalescence
+mechanism, which implies that the correct calculation of the curvature is
+important to capture the correct physical behavior.

+\section[Paper E]{Paper E:  Towards a second-order diffuse-domain approach for
+  solving PDEs in complex geometries}
+Karl Yngve Lervåg and John Lowengrub.  Submitted to Communications in Math.
+Sciences, 2013.
+
+\citet{Li09} developed a diffuse-domain method for solving partial-differential
+equations (PDEs) inside complex, dynamic geometries with Dirichlet, Neumann,
+and Robin boundary conditions.  This method is in the following referred to as
+DDM1.  They use the diffuse-domain approach~\cite{Kockelkoren03}, where the
+geometry is represented implicitly and the sharp boundary is replaced by
+a diffuse layer with a fixed interface width.  The original governing equations
+are then reformulated on a larger, regular domain and the boundary conditions
+are incorporated via singular source terms.  The method of matched asymptotic
+expansions is used to show that the reformulated problem converges
+asymptotically to the original problem.
+
+In the present paper, we use the method of matched asymptotic expansions to
+extend the DDM1 with include a high-order correction term in the diffuse
+formulation, cf.\ \cref{sec:DDM2}.  The extension is derived for elliptic
+problems with Neumann and Robin boundary conditions, where the correction term
+is shown to yield an asymptotically second-order accurate approximation of the
+original problem.  The new method is referred to as the DDM2.
+
+The DDM1 and DDM2 are compared for a selection of test problems.  The resulting
+equations were discretized by standard second-order central-difference schemes
+on uniform grids, and solved by a multigrid method.  A red-black Gauss-Seidel
+type iterative method was used as a smoother, see \cite{Wise07}.
+
+In addition to the comparison of DDM1 and DDM2, we compared two different
+approximations of the boundary conditions.  These correspond to different
+diffuse-interface surface delta functions, and for the Neumann boundary
+conditions they are
+\begin{equation}
+  \text{BC1} = |\grad\phi| g,
+\end{equation}
+and
+\begin{equation}
+  \text{BC2} = \epsilon|\grad\phi|^2 g.
+\end{equation}
+The approximations are similar for the Robin boundary condition, although here
+it was found that only BC1 resulted in a valid asymptotically second-order
+accurate DDM2.
+
+Our results show that the global accuracy and convergence of DDM2 is better
+than DDM1, however both methods perform well and the global convergence rate is
+around two for each.  The error was measured as the L$_2$ norm of the
+difference between an analytic solution and the solution $u_\epsilon$ for
+a given interface width, $\epsilon$.
+
+\Cref{fig:E1,fig:E2} show two of the results, the first one with the Neumann
+boundary conditions and the second with the Robin boundary condition.  The
+results indicate that DDM2 performs slightly better than DDM1.  They also show
+that the approximation BC1 gives more accurate results than BC2.  In
+particular, we found that with BC2 we needed much finer grids to obtain
+convergence for a given $\epsilon$.  For the smallest values of $\epsilon$ we
+were not able to refine the grids enough to obtain valid results.

+\chapter{Conclusions and outlook}
+\label{chap:conclusions}
+This thesis has considered two different problems:  The discretization of
+interface curvature and normal vectors with the level-set method and
+a diffuse-domain approach for solving partial-differential equations (PDEs) in
+complex domains.  In the following, some general concluding remarks and
+recommendations for further work are given.
+
+\section*{Conclusions}
+The first part of the thesis considered the modelling of incompressible
+two-phase flow.  The main motivation was to study two-phase flow phenomena that
+are relevant for compact heat exchangers, such as drop-drop and drop-film
+collisions.  In particular, the thesis addressed a challenge with the
+calculation of interface curvature and normal vectors with the level-set
+method.  Two methods were presented to handle the discretization in the kink
+regions: A curve-fitting discretization method (CFDM) and a local level-set
+extraction (LOLEX) method.  Both methods were shown to be robust in the kink
+regions, where the standard central-difference scheme (CD-2) fails.  Of these
+methods, the LOLEX method is the preferred method, because it relies on a less
+complicated algorithm that easily extends to 3D.
+
+CD-2 and the LOLEX method were used for simulations of drop-film collisions
+that were compared with experiments.  The results showed that CD-2 leads to
+errors in the curvature that cause unphysical pressure spikes during the
+coalescence.  The errors are shown to lead to a dissipation of kinetic energy
+during the collision and to a slower coalescence process.  The LOLEX method was
+shown to prevent these unphysical pressure spikes, and to produce to more
+accurate results.
+
+The second part of the thesis considered the diffuse-domain approach for
+solving PDEs in complex domains.  The main contribution, presented in Paper~E,
+was the derivation of an asymptotically second-order diffuse-domain method
+(DDM2) for solving elliptic problems in complex geometries with Neumann and
+Robin boundary conditions.  The new method is an extension by a high-order
+correction term of the method presented in \cite{Li09}, here called DDM1.  The
+DDM1 and DDM2 were compared, and the results indicated that the DDM2 was
+slightly better than the DDM1.
+
+The thesis has expanded on the results of Paper~E with a new asymptotic
+analysis that shows that DDM1 is in fact also asymptotically second order.
+This analysis helps to explain why the performance of DDM2 presented in Paper~E
+is only slightly better than that of DDM1.  As such, the new analysis leads to
+a better understanding of the DDM1 and the DDM2.
+
+\section*{Outlook}
+The following gives an outline of some possibilities for future work.
+\begin{itemize}
+  \item A natural continuation of this work is to perform more in-depth
+    comparisons of simulations with experiments for the drop-film collision
+    phenomenon that was started in Paper~D.  In addition, it would be
+    interesting to study other two-phase flow phenomena that are relevant for
+    heat-exchanger processes, for instance drop-drop collisions or flow across
+    tube bundles.  The latter requires the treatment of more complex boundaries,
+    which can be handled either with the diffuse-domain method or other methods
+    from the literature.
+  \item Paper~C gave a short comparison of the standard discretization method
+    (CD-2), the direction-difference scheme (DDS), and the curve-fitting
+    discretization scheme (CFDM) applied to the calculation of the normal
+    vectors.  The results showed that the CD-2 leads to inaccurate results in
+    the kink regions.  The DDS gives robust and accurate results in most cases,
+    but an example is given where only the CFDM yields an accurate result.
+    However, the impact of inaccurate calculations of the normal vector should
+    be investigated in more detail.  The normal vector is used both for the
+    solution of the level-set equations \eqref{eq:ls_adeq},
+    \eqref{eq:ls_velextr}, and \eqref{eq:ls_reinit}, and for the calculation of
+    the interface jumps \eqref{eq:jump_pressure} and \eqref{eq:jumptens}, so
+    one can expect that large errors in the calculation of the normal vector
+    may lead to large errors in the numerical solution.  This warrants
+    a further study.
+  \item Mass and heat transfer are obviously an important part of the
+    heat-exchanger processes.  The models that have been used in this thesis
+    should therefore be expanded with additional models for heat transfer and
+    mass transfer to enable the simulation of more relevant phenomena.
+  \item The DDM2 was only derived for problems with Robin and Neumann boundary
+    conditions.  If possible, it should be extended to also work with Dirichlet
+    boundary conditions.
+  \item As explained in Paper~E, we found that we were unable to solve the
+    discrete system of equations when the surface Laplacian part of the
+    correction term for the DDM2 was included.  A further investigation of this
+    problem should be done, and stable numerical methods to solve the full DDM2
+    equations should be developed.
+  \item The diffuse-domain approach is a promising method for solving problems
+    in complex and confined geometries with standard tools and methods.
+    \citet{Aland10} provide a diffuse-domain formulation of the Navier-Stokes
+    Cahn-Hilliard equations for incompressible two-phase flow and use it to
+    compute two-phase flow in both complex and confined geometries.  However,
+    they do not provide an asymptotic analysis of the reformulated equations to
+    show that the system converges.  Such an analysis would be interesting, in
+    particular to verify that the equations do converge to the original problem
+    when the interface width is decreased.
+  \item Finally, it would be interesting to develop a second-order
+    diffuse-domain formulation for the incompressible Navier-Stokes equations.
+    A starting point would be to use the results and techniques from this
+    thesis and Paper~E.

+\chapter{Introduction}
+This thesis considers the mathematical modelling and numerical computation of
+two-phase flows.  It focuses on developing more robust numerical methods to
+calculate the curvature and the normal vector of the interface between the two
+phases.  In addition it considers a diffuse-domain method for solving partial
+differential equations in complex geometries, and it derives an asymptotically
+second-order method for elliptic problems.
+
+\section{Background and motivation}
+Two-phase flows are particular examples of multiphase flows of gas and liquid
+with an interface that separates the two phases.  In the pedantic sense,
+two-phase flow is flow of a single fluid that occurs as two different phases,
+for example steam and water.  However, it is common to be more general, and in
+this thesis we use the term two-phase flow also for immiscible mixtures of
+different fluids, such as water and oil.
+
+Two-phase flows are crucial to a large amount of processes, both in nature and
+in industry.  Examples range from weather phenomena, such as rain drops falling
+through air, to industrial processes, for instance the separation of water from
+oil.  In general, multiphase flow phenomena influence any process where liquids
+and gases are involved.  In the oil and gas industry, most processes are
+two-phase or multiphase flow processes.  Needless to say, the understanding of
+these phenomena is fundamental in the development of new or improved processes.
+
+Consider the international trade of liquefied natural gas (LNG), which is
+a particular branch of the oil and gas industry that has undergone an
+exceptional growth in the last decades.  There is a strong focus both in Norway
+and internationally on producing LNG on large floaters
+(FLNG)\footnote{FLNG facilities do not yet exist, although a facility is under
+  development by Royal Dutch Shell~\cite{Prelude1}.  The construction of this
+  facility was started in 2012, and the first drilling is stated to commence in
+  2013~\cite{Prelude2}.}.  There are a number of both environmental and
+economic advantages of such FLNG facilities.  In particular, FLNG facilities
+would remove the need of long pipelines from the gas fields to the shore, there
+would be no requirement for compression units to pump the gas to the shore, and
+one would not need to construct onshore production facilities.  This would
+significantly reduce the environmental footprint, and would help preserve
+marine and coastal environments.  Since an FLNG facility can be moved to a new
+location when a field has been depleted, it would make it economically viable
+to open up new business opportunities to develop offshore gas fields that would
+otherwise remain stranded.
+
+Moving the LNG production to an offshore facility presents a demanding set of
+challenges.  A particular challenge is that the elements of a conventional LNG
+facility need to fit into an area roughly one quarter the original size.  Heat
+exchangers are among the main challenges in the design and operation of LNG
+plants \cite{Hesselgreaves01}.  Compact and efficient heat exchangers are
+needed to obtain an energy efficient plant with low emissions.  More optimized
+designs require more accurate tools for design and operation.  Such tools can
+only come as a result of an improved physical understanding of the complex
+two-phase flows occurring in the heat exchangers.  This can be achieved by more
+detailed mathematical modelling, together with dedicated laboratory
+observations, cf.\ \cite{Olsen07}.
+
+\section{Overview of methods for two-phase flow simulations}
+In the following, a brief overview is given of different methods for modelling
+two-phase flows where the interface location is known.  In particular, we focus
+on methods that handle the interface evolution.  For more in-depth reviews, see
+for instance \cite{Cristini04,Scardovelli99,Sethian03}.
+
+Interface propagation methods comprise a range of methods that are often
+categorised as either front tracking or front capturing.  Front-tracking
+methods use Lagrangian particles to track the interface
+explicitly~\cite{Tryggvason01}, while front-capturing methods use an Eulerian
+approach to capture the interface implicitly.  Examples of the latter are
+volume-of-fluid methods~\cite{Scardovelli99,Tryggvason11}, phase-field
+methods~\cite{Anderson98,Jacqmin99,Lowengrub98}, and level-set
+methods~\cite{Osher03}.
+
+The main advantages of front-tracking methods are their inherent accuracy and
+that topological changes do not occur without explicit action.  Hence,
+unphysical numerical reconnection does not occur.  This means that if front
+tracking is used for the simulations of two drops that collide, these drops
+will not coalesce due to numerical reconnection or merging.  However, the
+handling of topological changes are challenging, in particular in three
+dimensions~\cite{Shin02}.  Also, there are some issues of numerical
+instabilities, as discussed by \citet{Sethian85} and \citet{Osher88}.
+
+The volume-of-fluid method utilizes a volume-fraction function whose values
+represent the characteristic function of one of the fluid domains.  Its values
+are zero or one, except in those cells cut by the interface.  A considerable
+advantage of the volume-of-fluid method is that it conserves the mass of both
+fluids well.  However, the reconstruction of the interface from volume
+fractions is not simple, and computation of geometric quantities such as the
+interface curvature is not straightforward.  Also, spurious bubbles and drops
+may be created, cf.\ \cite{Lafaurie94}.
+
+The phase-field methods treat the interface in a diffuse manner, where the
+fluid properties, such as density and viscosity, change rapidly but smoothly
+across the interface.  These methods typically solve the coupled
+Cahn-Hilliard/Navier-Stokes equations, where the Cahn-Hilliard equation is
+based on the free energy of an interface~\cite{Cahn57}.  Through this energy
+formulation, one can model more advanced interface physics such as van der
+Waals interactions, electrostatic forces, and fluids with varying
+miscibilities.  However, the phase-field methods require that one resolves very
+small length scales at the interfaces.  This poses a severe restriction on the
+applicability of phase-field methods for two-phase flow, where the length
+scales of the flow are generally much larger than those of the interface.
+
+In this thesis, we have used the level-set method~\cite{Osher88}, which
+implicitly captures the interface as an isocontour of a function defined in the
+entire domain.  The main motivation of this choice is both that the level-set
+method handles topological changes of evolving interfaces automatically,
+cf.~\citet{Sethian03}, and that it is relatively straightforward to implement.
+
+It should be noted that the automatic handling of topological changes is not
+based on physical principles.  For instance, when two interfaces approach each
+other and their distance becomes less than the spacing of the grid, the
+level-set method can no longer resolve both interfaces and so they are merged.
+An important consequence is that the level-set method does not model the
+physics involved in the coalescence process, and in particular in the smaller
+scales of the film-drainage process.  This process involves a wide range of
+length scales, varying from the nanometer scale where van der Waals force are
+active to the length scales of the external flow.  Some effort has been made to
+include the effects of the smaller scales in front-capturing methods,
+cf.~\cite{Nobari96,Tryggvason10}.  Recently, \citet{Kwakkel13} presented
+a level-set/volume-of-fluid method that is coupled with a film-drainage model
+that predicts if and when two colliding droplets will coalesce.  To prevent the
+numerical coalescence, each droplet has its own locally defined level-set
+function.
+
+The level-set method has been used to model several diverse phenomena,
+such as tumour growth~\cite{Macklin06,Macklin05,Macklin08}, propagation of
+wildland fire~\cite{Mallet09}, and computer RAM production~\cite{Melicher08}.
+For a good and thorough introduction to the level-set method, see
+\cite{Osher03}.
+
+A weakness of the level-set method is that it does not conserve the mass of the
+two fluids, in particular in areas of low resolution and/or high curvature.
+Different approaches have been developed to overcome this disadvantage, for
+example the conservative level-set method~\cite{Olsson05,Olsson07}, the
+particle level-set method~\cite{Enright02}, or the coupled
+level-set/volume-of-fluid method~\cite{Sussman00}.
+
+When we use the level-set method to capture the interface for immiscible and
+incompressible two-phase flow simulations, there will be a sharp change in the
+density and viscosity across the interface.  In this thesis we use the
+ghost-fluid method~\cite{Fedkiw99}, which is a sharp-interface method where the
+jumps are included in the spatial discretizations in a sharp manner.  An
+alternative method is the continuous surface-force method introduced by
+\citet{Brackbill92}, where the density and the viscosity are smeared out across
+the interface through a smoothed Heaviside function.
+

+\section{Goal and contribution of the present thesis}
+The main goal of the PhD project has been to develop fundamental knowledge of
+two-phase flow phenomenon that are relevant for compact heat exchangers.
+
+In order to do detailed theoretical studies of phenomena that are relevant for
+compact heat exchangers, we need to consider two-phase flows with mass and heat
+transfer in confined and complex geometries.  One such relevant phenomenon is
+the drop-film collision process \cite{Zhao09}.  Even when restricted to
+isothermal and immiscible flows, this simple phenomenon remains a challenge.
+When the level-set method is used to capture the interface, one must be
+particularly careful about how one calculates the interface curvature and
+normal vector.  For instance, when two drops are in near collision there is
+a kink region in the level-set function between the drops, where the gradient
+is discontinuous, see \cref{fig:curvature-problem}.  This discontinuity may
+lead to large errors in the curvature and the normal vector if it is not taken
+into account in the discretization stencils.

+
+As a step towards computing two-phase flow simulations in confined geometries,
+the thesis has considered the diffuse-domain method~\cite{Li09}.  This is
+a method where partial-differential equations in complex domains are extended
+into larger, regular domains with the use of diffuse approximations of the
+physical boundaries.  The approximations converge asymptotically to the
+original problem when the width of the diffuse boundary is reduced.  With this
+method one can use standard numerical methods to solve equations that
+incorporate complex boundaries.
+
+The main contributions of the present thesis are two new methods to calculate
+the curvature and normal vector in a robust manner with the level-set method.
+These methods are shown to yield more accurate calculations of drop-film and
+drop-drop collisions.  The methods are compared with standard methods and with
+other methods from the literature.
+
+In addition, the thesis presents an extension of a diffuse-domain method by
+a high-order correction term for the solution of elliptic problems in complex
+geometries.  New analysis provided in the thesis improves the understanding of
+the diffuse-domain method, and the derived method is shown to be more accurate
+than the existing diffuse-domain method.
+
+\section{Outline of the thesis}
+The thesis is organised as follows: \Cref{chap:two-phase-flow} gives a brief
+overview of the derivation of the governing equations for two-phase flow.  It
+includes a consideration of the fluid-fluid interface conditions and the
+derivation of a simplified jump tensor for the viscous term at the interface.
+
+\Cref{chap:numerical-methods} gives a detailed description of the numerical
+methods that are used to solve the two-phase flow equations.  In particular, it
+describes the level-set method, which is used to capture the interfaces,
+projection methods that are used to solve the Navier-Stokes equations, and the
+spatial and temporal discretization schemes.  At the end of the chapter, an
+overview of the novel discretization methods for the curvature and the normal
+vector is given.
+
+\Cref{chap:diffuse-domain} gives a short introduction to the diffuse-domain
+method for an elliptic problem with Neumann boundary conditions.  It introduces
+the high-order correction term, and shows that the new method converges
+asymptotically with second-order to the original problem.  The chapter presents
+new analysis that shows that the correction term is not necessary for
+second-order convergence.
+
+In \cref{chap:contributions} the main results of the contributed papers A--E
+are summarized, and the author's contributions are highlighted.  Finally,
+\cref{chap:conclusions} gives concluding remarks and provides an outlook for
+future work.

+Full-text versions of the research papers A--E are provided in the Appendices

+\chapter{Governing equations for two-phase flow}
+\label{chap:two-phase-flow}
+In this chapter we will give a brief overview of the derivation of the
+governing equations for two-phase flow.  We begin with a consideration of the
+Navier-Stokes equations for single-phase flow.  We then introduce a singular
+surface-force term and derive the Navier-Stokes equations for two-phase flow.
+Finally, we use the Navier-Stokes equations for two-phase flow to derive jump
+conditions at the interface between the phases.
+
+\section{The Navier-Stokes equations for single-phase flow}
+The following is a brief derivation of the Navier-Stokes equations for
+single-phase flows.  For a more thorough derivation of these equations, see for
+instance \citet[§4 and §5]{Aris89} or \citet[Chapter~4]{White03}.
+
+We consider a single-phase, viscous flow in some domain $\Omega$ with boundary
+$\partial\Omega$.  When temperature effects are neglected the flow is described
+by the Cauchy equation
+\begin{equation}
+  \label{eq:cauchy_equation}
+  \rho\left(\cd{\vct u}\right) = \div\tenstr+\rho\vct f,
+\end{equation}
+and the mass conservation equation,
+\begin{equation}
+  \label{eq:cons_of_mass}
+  \pdt\rho + \div(\rho\vct u) = 0.
+\end{equation}
+Here $\rho$ is the fluid density, $\vct u$ is the flow velocity, $t$ is time,
+$\tenstr$ is the stress tensor, $\vct f$ denotes body forces, and $\del$ is
+used to denote the gradient and divergence operators.  The stress tensor for
+Newtonian fluids with zero bulk viscosity is
+\begin{equation}
+  \tenstr = -p\tenI + 2\mu\tenD - \frac 2 3\mu (\trace\tenD) \tenI,
+  \label{eq:viscous_stress_tensor}
+\end{equation}
+where $p$ is the pressure, $\tenI$ is the identity tensor, $\mu$ is the dynamic
+viscosity, and $\trace\tenD$ denotes the trace of the strain-rate tensor
+$\tenD$,
+\begin{equation}
+  \tenD = \frac{1}{2}\left( \grad\vct u + (\grad\vct u)^T \right).
+  \label{eq:deformation_tensor}
+\end{equation}
+For incompressible flow, the mass-conservation equation reduces to
+\begin{equation}
+  \label{eq:navier-stokes-1}
+  \div\vct u = 0,
+\end{equation}
+that is, the velocity field must be divergence free.  If we further assume that
+the viscosity is constant, then it follows that the divergence of the stress
+tensor reduces to
+\begin{equation}
+  \label{eq:stress_tensor}
+  \div\tenstr = -\grad p + \mu\lapl\vct u,
+\end{equation}
+and so the Cauchy equation \eqref{eq:cauchy_equation} becomes
+\begin{equation}
+  \rho\left(\cd{\vct u}\right) = -\grad p + \mu\lapl\vct u + \rho\vct f.
+  \label{eq:navier-stokes-2}
+\end{equation}
+Equations \eqref{eq:navier-stokes-1} and \eqref{eq:navier-stokes-2} are the
+incompressible Navier-Stokes equations for single-phase flow with constant
+viscosity.
+
+\section{The Navier-Stokes equations for two-phase flow}
+We now consider an immiscible two-phase flow of two Newtonian fluids, each with
+its own viscosity and density.  We let $\Omega_1$ and $\Omega_2$ denote the
+domains occupied by fluid 1 and fluid 2, respectively, and let the interface
+between the fluids be denoted by $\Gamma$.  Then $\Omega
+= \Omega_1\cup\Omega_2$ and $\partial\Omega
+= (\partial\Omega_1\cup\partial\Omega_2)\setminus\Gamma$ are the fluid domain
+and its boundary, respectively.  See \cref{fig:domain} for an illustration of
+a two-phase flow domain.

+    separates the two phases $\Omega_1$ and $\Omega_2$.}
+  \label{fig:domain}
+\end{figure}
+
+The extension of the single-phase model to account for two fluids can be made
+by adding a singular surface-force term to represent the effects of surface
+tension between the fluids.  We assume that the surface tension is constant, in
+which case the singular surface force can be defined as
+\begin{equation}
+  \funssf(\vct x,t)
+  = \int_{\Gamma}\sigma\kappa\vct n\delta(\vct x - \vct x_I(\vct s))\dif\vct s,
+  \label{eq:ssf}
+\end{equation}
+where $\sigma$ is the surface tension, $\kappa$ is the local curvature, $\vct
+n$ is the normal vector, $\delta$ is the Dirac delta function, and $\vct
+x_I(\vct s)$ is a parametrisation of the interface.  Thus the Navier-Stokes
+equations for immiscible and incompressible two-phase flow are
+\begin{align}
+  \label{eq:ns1}
+  \div\vct u &= 0, \\

+\section{Fluid-fluid interface conditions}
+The surface-tension force and the jump in viscosity and density across the
+interface $\Gamma$ lead to a set of interface conditions that must be satisfied
+along the interface $\Gamma$.  The following is a brief derivation of these
+conditions.
+
+First, we only consider flows where there is no mass transfer, which implies
+that
+\begin{equation}
+  \jmp{\vct u}\cdot\vct n = 0,
+\end{equation}
+where $\jmp{\cdot}$ denotes the jump at the interface, for instance $\jmp{\mu}
+= \mu_2 - \mu_1$.  Further, for viscous flows there is no slip at the
+interface, and thus the tangential velocity component of the two fluids must be
+equal at the interface,
+\begin{equation}
+  \jmp{\vct u}\cdot\vct t = 0.
+\end{equation}
+It follows that
+\begin{align}
+  \label{eq:jmpu}
+  \jmp{\vct u} &= 0, \\
+  \label{eq:jmpJut}
+  \jmp{\grad \vct u}\cdot\vct t &= 0.
+\end{align}
+The latter is a direct consequence of the former.  Both fluids are
+incompressible, which gives the trivial identity $\jmp{\div\vct u} = 0$.  If we
+use the identity
+\begin{equation}
+  \div\vct u
+    = \vct n\cdot\grad\vct u\cdot\vct n + \vct t\cdot\grad\vct u\cdot\vct t
+  \label{eq:divuident}
+\end{equation}
+together with \eqref{eq:jmpJut} we get
+\begin{equation}
+  \vct n\cdot\jmp{\grad\vct u}\cdot\vct n = 0,
+  \label{eq:jmpngradun}
+\end{equation}
+which means that the normal component of the normal derivative of the velocity
+field is continuous across the interface.  Note that in \eqref{eq:divuident}
+and in similar expressions in the following, the nabla operator is only applied
+to $\vct u$, not the normal and tangential vectors that follow.

+  \end{tikzpicture}
+  \caption{A sketch of the control volume $\Omega_\epsilon$ that covers the
+    interface, $\Gamma$.}
+  \label{fig:domain_omega_epsilon}
+\end{figure}%
+Next, we consider the conservation of momentum.  We define a control volume
+\begin{equation}
+  \Omega_{\epsilon} = \set{\vct x \in \Omega}{\min_{\vct x_I \in \Gamma}|\vct
+    x - \vct x_I| \leq \epsilon},
+\end{equation}
+where $\epsilon > 0$, see \cref{fig:domain_omega_epsilon}.  We then integrate
+the Cauchy equation \eqref{eq:cauchy_equation} with the added singular
+surface-force term over the domain~$\Omega_\epsilon$,
+\begin{multline}
+  \intoepdx{\rho\td{\vct u}}
+    = \intoepdx{\div\tenstr} + \intoepdx{\rho\vct f} \\
+      + \intoepdx{ \int_{\Gamma}\sigma\kappa\vct n\delta(\vct x - \vct
+        x_I(\vct s))\dif\vct s}.
+\end{multline}
+Here $\tdi{\vct u} = \partial\vct u/\partial t + \vct u\cdot\grad\vct u$
+denotes the convective derivative.  Now we apply the Gauss theorem and change
+the order of integration in the last term to obtain
+\begin{equation}
+  \intoepdx{\rho\td{\vct u}} = \intdoepds{\tenstr\cdot\vct n}
+    + \intoepdx{\rho\vct f} + \int_\Gamma\sigma\kappa\vct n\dif\vct s.
+\end{equation}
+If we let $\epsilon$ go to zero, the left-hand side and the second term on the
+right-hand side vanish, and we get
+\begin{equation}
+  0 = \int_\Gamma\left( \jmp{\tenstr}\cdot\vct n + \sigma\kappa\vct
+    n \right)\dif s.
+  \label{eq:stressjumpint}
+\end{equation}
+Since the derivation above is also valid for any subset of $\Omega_\epsilon$
+containing a part of $\Gamma$, \eqref{eq:stressjumpint} must hold for any part
+of $\Gamma$.  Therefore
+\begin{equation}
+  0 = \jmp{\vct T}\cdot\vct n + \sigma\kappa\vct n.
+\end{equation}
+With $\vct T = -p\vct I + 2\mu\vct D$ we finally get the interface condition
+for the stresses,
+\begin{equation}
+  \label{eq:stress_jump}
+  \jmp{p}\vct n - \jmp{2\mu\tenD}\cdot\vct n = \sigma\kappa\vct n.
+\end{equation}
+The surface tension force is seen to introduce a discontinuity in the normal
+stresses across the interface.  The tangential stresses are continuous.
+
+\section{Interface conditions for the pressure and the viscous term}
+The previous section gave a brief derivation of the interface conditions for
+immiscible and incompressible two-phase flow without mass transfer.  In order
+to use these conditions for the discretization of the Navier-Stokes equations
+\eqref{eq:ns1} and \eqref{eq:ns2}, we need to rewrite them into a more suitable
+form.  In particular, we want to find explicit expressions for the jump in the
+pressure $\jmp p$ and the viscous term $\jmp{\mu\grad\vct u}$.  The following
+derivation is based on \cite{Hansen05} and \cite{Kang00}.
+
+First, a jump condition for the pressure is obtained by taking the inner
+product of \eqref{eq:stress_jump} with the normal vector $\vct n$,
+\begin{equation}
+  \jmp p = \vct n\cdot\jmp{2\mu\tenD}\cdot\vct n + \sigma\kappa
+      = 2\jmp{\mu}\vct n\cdot \grad\vct u \cdot\vct n
+        + \sigma\kappa,
+  \label{eq:jump_pressure}
+\end{equation}
+where \eqref{eq:jmpngradun} was used for the second equality.
+
+To find the jump in the viscous term, it is first decomposed into an interface
+normal coordinate system as
+\begin{equation}
+  \begin{split}
+    \jmp{\mu\grad\vct u} &=
+  \left(\vct n\cdot\jmp{\mu\grad\vct u}\cdot\vct n\right)\vct n\otimes\vct n +
+  \left(\vct t\cdot\jmp{\mu\grad\vct u}\cdot\vct t\right)\vct t\otimes\vct t
+        \\ &\quad+
+  \left(\vct n\cdot\jmp{\mu\grad\vct u}\cdot\vct t\right)\vct n\otimes\vct t +
+  \left(\vct t\cdot\jmp{\mu\grad\vct u}\cdot\vct n\right)\vct t\otimes\vct n,
+  \end{split}
+\end{equation}
+where $\otimes$ denotes the dyadic product.  We already showed that
+$\jmp{\grad\vct u}\cdot\vct t = 0$ and $\vct n\cdot\jmp{\grad\vct u}\cdot\vct
+n = 0$, cf.\ \eqref{eq:jmpJut} and \eqref{eq:jmpngradun}, which gives
+\begin{align}
+  \vct n\cdot\jmp{\mu\grad\vct u}\cdot\vct n &=
+    \jmp{\mu}\,\vct n\cdot\grad\vct u\cdot\vct n, \\
+  \vct t\cdot\jmp{\mu\grad\vct u}\cdot\vct t &=
+    \jmp{\mu}\,\vct t\cdot\grad\vct u\cdot\vct t, \\
+  \vct n\cdot\jmp{\mu\grad\vct u}\cdot\vct t &=
+    \jmp{\mu}\,\vct n\cdot\grad\vct u\cdot\vct t.
+\end{align}
+We then take the inner product of \eqref{eq:stress_jump} with $\vct t$, which
+gives
+\begin{equation}
+  \vct t\cdot\jmp{\mu\left(\grad\vct u + (\grad\vct u)^T \right)}\cdot\vct n
+  = \vct t\cdot\jmp{\mu\grad\vct u} \cdot\vct n
+    + \jmp{\mu}\vct n\cdot\grad\vct u \cdot\vct t
+  = 0,
+\end{equation}
+or
+\begin{equation}
+  \vct t\cdot\jmp{\mu\grad\vct u}\cdot\vct n =
+    - \jmp{\mu}\vct n\cdot\grad\vct u \cdot\vct t.
+\end{equation}
+The jump in the viscous term becomes
+\begin{multline}
+  \jmp{\mu\grad\vct u} = \jmp{\mu} \Big(
+       (\vct n\cdot\grad\vct u\cdot\vct n)\vct n\otimes\vct n
+     + (\vct n\cdot\grad\vct u\cdot\vct t)\vct n\otimes\vct t \\
+     - (\vct n\cdot\grad\vct u\cdot\vct t)\vct t\otimes\vct n
+     + (\vct t\cdot\grad\vct u\cdot\vct t)\vct t\otimes\vct t \Big).
+\end{multline}
+This can be simplified further by noting that
+\begin{equation}
+  (\grad\vct u\cdot t)\otimes\vct t
+  = (\vct n\cdot\grad\vct u\cdot\vct t)\vct n\otimes\vct t
+    + (\vct t\cdot\grad\vct u\cdot\vct t)\vct t\otimes\vct t.
+\end{equation}
+Thus we obtain the expression for the jump in the viscous term that has been
+used in the present work,
+\begin{multline}
+  \jmp{\mu\grad\vct u} = \jmp{\mu} \Big(
+       (\vct n\cdot\grad\vct u\cdot\vct n)\vct n\otimes\vct n
+     - (\vct n\cdot\grad\vct u\cdot\vct t)\vct t\otimes\vct n \\
+     + (\grad\vct u\cdot\vct t)\otimes\vct t \Big).
+  \label{eq:jumptens}
+\end{multline}
+
+\section{Summary}

+\chapter{Numerical methods}
+\label{chap:numerical-methods}
+This chapter describes the numerical methods that have been used in this thesis
+to solve the Navier-Stokes equations for two-phase flow.  First, a brief
+introduction to the level-set method is given, which is followed by an outline
+of the two projection methods that have been used to solve the Navier-Stokes
+equations.  The spatial and temporal discretization methods are then
+summarized, and at the end of the chapter the new methods to calculate the
+curvature and the normal vectors are presented.
+
+\section{The level-set method}
+\label{sec:level-set}
+In order to solve the Navier-Stokes equations for two-phase flow, we need to
+know the location of the interface.  The level-set method proposed by
+\citet{Osher88} allows us to capture the interface location as the zero level
+set of the level-set function $\varphi(\vct x,t)$.  The level-set function is
+typically defined as a signed-distance function,
+\begin{equation}
+  \varphi(\vct x,t) = \begin{cases}
+     d(\vct x,t) & \text{if } \vct x\in\Omega_2, \\
+    -d(\vct x,t) & \text{if } \vct x\in\Omega_1, \\
+  \end{cases}
+\end{equation}
+where $d(\vct x,t)$ is the shortest distance to the interface $\Gamma$,
+\begin{equation}
+  d(\vct x,t) = \min_{\vct x_I \in \Gamma} |\vct x - \vct x_I|.
+\end{equation}
+Thus the interface can be defined implicitly as
+\begin{equation}
+  \Gamma(t) = \set{\vct x\in\Omega}{\varphi(\vct x,t)=0},
+              \quad t\in \mathbb R^+.
+\end{equation}
+
+The position of the interface is updated by solving an advection equation for
+$\varphi$,
+\begin{equation}
+  \label{eq:ls_adeq}
+  \pdt{\varphi} + \vct{\hat u}\cdot\grad\varphi = 0,
+\end{equation}
+where $\vct{\hat u}$ is the velocity at the interface extended to the entire
+domain.  We extend the interface velocity through solving
+a velocity-extrapolation equation,
+\begin{equation}
+  \label{eq:ls_velextr}
+  \pd{\vct{\hat u}}{\tau} + S(\varphi)\vct n\cdot\grad\vct{\hat u} = 0,
+  \quad \vct{\hat u}_{\tau=0} = \vct u,
+\end{equation}
+to steady state, cf.\ \cite{Adalsteinsson99,Zhao96}.  Here $\tau$ is
+a pseudo-time and $S$ is a smeared sign function which is equal to zero at the
+interface,
+\begin{equation}
+  S(\varphi) = \frac{\varphi}{\sqrt{\varphi^2+2\Delta x^2}}.
+\end{equation}
+
+When we solve the level-set equation \eqref{eq:ls_adeq}, the non-uniform
+advection will distort the signed-distance property of the level-set function,
+and numerical dissipation error adds to this distortion.  The level-set
+function is therefore reinitialized regularly by solving
+\begin{equation}
+  \label{eq:ls_reinit}
+  \begin{split}
+    \pd{\varphi}{\tau} + S(\varphi_0)(|\grad\varphi|-1) &= 0, \\
+    \varphi(\vct x,0) &= \varphi_0(\vct x),
+  \end{split}
+\end{equation}
+to steady state as proposed by \citet{Sussman94}.  The level-set function just
+before initialization is used as the initial condition $\varphi_0$.
+
+The level-set equations \eqref{eq:ls_adeq}, \eqref{eq:ls_velextr}, and
+\eqref{eq:ls_reinit} are discretized in time and space as described in the
+following sections.  The method presented by \citet{Adalsteinsson95} is used to
+improve the computational speed.  The method is often called the narrow-band
+method, since the level-set function is only updated in a narrow band across
+the interface at each time step.
+
+One of the advantages of the level-set method is that normal vectors and
+curvatures can be readily calculated from the level-set function, that is,
+\begin{align}
+  \label{eq:norm}
+  \vct n &= \frac{\grad\varphi}{|\grad\varphi|}, \\
+  \label{eq:curv}
+  \kappa &= \div\left(\frac{\grad\varphi}{|\grad\varphi|}\right).
+\end{align}
+
+\section{Projection methods}
+\label{sec:projection-method}
+We have employed two different projection methods in this thesis to solve the
+incompressible Navier-Stokes equations for two-phase flow \eqref{eq:ns1} and
+\eqref{eq:ns2}.  Papers A, B, and C used the direct projection
+scheme~1~(DP1)~\cite{Hansen05}, and Paper D used the more standard Chorin
+projection method \cite{Chorin68}.
+
+The projection methods are a family of methods for the solution of the
+incompressible Navier-Stokes equations that are based on the Helmholtz-Hodge
+theorem.  This theorem states that an arbitrary vector field can be decomposed
+into a divergence-free part and a rotation-free part.  That is, any vector
+field $\vct a$ can be written as
+\begin{equation}
+  \vct a = \vct a' + \grad\psi,
+\end{equation}
+where $\vct a'$ is a vector with $\div\vct a' = 0$ and $\psi$ is a scalar
+potential.  The proof of this theorem can be found in for instance
+\cite[§3.44]{Aris89} or \cite{Chorin00}.
+
+\subsection{The direct projection scheme 1}
+The DP1 was developed by \citet{Hansen05} and is based on a direct application
+of the Helmholtz-Hodge theorem.  We assume that the velocity $\vct u$ is
+sufficiently smooth, and then rewrite \eqref{eq:navier-stokes-2} to get
+\begin{equation}
+  \label{eq:divFreeVel}
+  \pdt{\vct u} = \vct w - \frac{\grad p}{\rho},
+\end{equation}
+where
+\begin{equation}
+  \vct w = - (\vct u\cdot\grad)\vct u + \nu\grad^2\vct u + \vct f.
+  \label{eq:continuousRightHandVector}
+\end{equation}
+The divergence of \eqref{eq:divFreeVel} yields a Poisson equation for the
+pressure,
+\begin{equation}
+  \div\left(\frac{\grad p}{\rho}\right) = \div\vct w.
+  \label{eq:PoissonDP1}
+\end{equation}
+The DP1 scheme follows from a direct numerical discretization of the above
+equations.  First, $\vct w$ is calculated with
+\eqref{eq:continuousRightHandVector}.  Then the pressure is found by solving
+the Poisson equation \eqref{eq:PoissonDP1}.  Finally, an Euler step is used to
+solve \eqref{eq:divFreeVel}, that is,
+\begin{equation}
+  \vct u^{n+1} = \vct u^n + \Delta t\left(\vct w - \frac{\grad p}{\rho}\right).
+  \label{eq:dp1-update}
+\end{equation}
+
+\subsection{The Chorin projection method}
+The Chorin projection method was presented by \citet{Chorin68}, and is today
+one of the standard methods for solving the Navier-Stokes equations, e.g.\
+\cite{Walker12}.  The method is briefly presented in the following.
+
+Let $\Delta t$ be the time step, and consider the discretization of the
+momentum equation \eqref{eq:navier-stokes-2} with the forward Euler method,
+\begin{equation}
+  \frac{\vct u^{n+1} - \vct u^n}{\Delta t}
+  = -\vct u^n\cdot\grad\vct u^n
+    - \frac{\grad p^{n+1}}{\rho} + \frac\mu\rho\lapl\vct u^n + \vct f,
+  \label{eq:discmomeq}
+\end{equation}
+where $\vct u^n\equiv\vct u(\vct x,n\Delta t)$ and $p^n\equiv p(\vct x,n\Delta
+t)$ are assumed known at time level $n$.  Note that the pressure gradient is
+evaluated at time level $n+1$.  Next, to solve \eqref{eq:discmomeq} in two
+steps, we introduce the intermediate velocity field $\vct u^\star$,
+\begin{equation}
+  \frac{\vct u^{n+1} - \vct u^\star + \vct u^\star - \vct u^n}{\Delta t}
+  = -\vct u^n\cdot\grad\vct u^n
+    - \frac{\grad p^{n+1}}{\rho} + \frac\mu\rho\lapl\vct u^n + \vct f,
+\end{equation}
+which is chosen such that
+\begin{align}
+  \label{eq:ustar}
+  \frac{\vct u^\star - \vct u^n}{\Delta t}
+    &= -\vct u^n\cdot\grad\vct u^n + \frac\mu\rho\lapl\vct u^n + \vct f, \\
+  \label{eq:unext}
+  \frac{\vct u^{n+1} - \vct u^\star}{\Delta t} &= - \frac{\grad p^{n+1}}{\rho}.
+\end{align}
+From \eqref{eq:ustar} we get an explicit expression for $\vct u^\star$,
+\begin{equation}
+  \vct u^{\star} = \vct u^n
+    + \Delta t\left(-\vct u^n\cdot\grad\vct u^n
+        + \frac\mu\rho\,\lapl\vct u^n + \vct f\right).
+\end{equation}
+Next, the divergence of \eqref{eq:unext} and $\div\vct u^{n+1} = 0$ yields
+a Poisson equation for the pressure,
+\begin{equation}
+  \div\left(\frac{\grad p^{n+1}}{\rho}\right)
+    = \frac{\div\vct u^\star}{\Delta t}.
+  \label{eq:PoissonChorin}
+\end{equation}
+Finally, we obtain for \eqref{eq:unext}
+\begin{equation}
+  \vct u^{n+1} = \vct u^\star - \Delta t\frac{\grad p^{n+1}}{\rho}.
+  \label{eq:velcorrection}
+\end{equation}
+
+\section{Spatial discretization}
+\label{sec:x-discr}
+The governing equations \eqref{eq:ns1}, \eqref{eq:ns2}, \eqref{eq:ls_adeq},
+\eqref{eq:ls_velextr}, and \eqref{eq:ls_reinit} are discretized on a staggered
+grid~\cite{Harlow65}, where the scalar values are located at the cell centres
+and the vector values are located at the cell edges, see
+\cref{fig:staggered-grid}.  The domain boundary coincides with cell edges, and
+the fixed grid spacing is $\Delta x$ in the $x$ direction and $\Delta y$ in the
+$y$ direction.

+respectively.  Here $\vct u = (u,v)$ is a vector and $p$ is a scalar.  Note
+that the gradient of a scalar is a vector and has values located at the cell

+gradient returns a vector with components defined on the cell faces, while the
+divergence and the Laplacian returns a scalar defined at the cell centres.
+
+\subsection{Advective terms}
+The advective terms, $\vct u\cdot\grad\vct u$ in the momentum equation
+\eqref{eq:ns2} and $\vct{\hat u}\cdot\grad\varphi$ in the level-set equation
+\eqref{eq:ls_adeq}, and the normal derivative $\vct n\cdot\grad\vct{\hat u}$ in
+the velocity-extrapolation equation \eqref{eq:ls_velextr} are discretized with
+the weighted essentially non-oscillatory (WENO) scheme, cf.~\cite{Fedkiw99}
+and~\cite{Jiang96}.  The WENO scheme is a high-order upwind scheme that is
+fifth-order accurate in smooth regions.  In nonsmooth regions the accuracy is
+reduced to a minimum of third order.  The following is a brief outline of the
+WENO scheme.
+
+First, when we calculate the advective term for the velocity, the vector
+components are required on all cell edges.  That is, we must interpolate the
+$x$-component of the velocity to the location of the $y$-component of the
+velocity and vice versa.  To do this we use a linear interpolation,
+\begin{align}
+  u_{i,j+\frac 1 2} &= \frac 1 4\left(
+      u_{i-\frac 1 2,j  } + u_{i-\frac 1 2,j+1}
+    + u_{i+\frac 1 2,j+1} + u_{i+\frac 1 2,j  } \right), \\
+  v_{i+\frac 1 2,j} &= \frac 1 4\left(
+      v_{i,  j-\frac 1 2} + v_{i+1,j-\frac 1 2}
+    + v_{i+1,j+\frac 1 2} + v_{i  ,j+\frac 1 2} \right).
+\end{align}
+
+Similarly, when we calculate the advective term for the level-set function
+$\varphi$, we first interpolate the velocity to the scalar grid,
+\begin{align}
+  u_{i,j} &= \frac 1 2\left( u_{i+\frac 1 2,j} + u_{i-\frac 1 2,j} \right), \\
+  v_{i,j} &= \frac 1 2\left( v_{i,j+\frac 1 2} + v_{i,j-\frac 1 2} \right).
+\end{align}
+
+We now consider the WENO scheme for the advective operator in 1D at the point
+$x_{i+\frac 1 2}$.  The scheme extends naturally to higher dimensions.  First,
+if $u_{i+\frac 1 2} = 0$, then
+\begin{equation}
+  \left. u\pd u x \right|_{i+\frac 1 2} = 0.
+\end{equation}
+Otherwise we need to calculate a set of five differences that depend on the
+upwind direction.  The differences are denoted $\Delta v_k$ for $k=1,\dots,5$.
+If $u_{i+\frac 1 2}>0$, then we calculate
+\begin{equation}
+  \Delta v_k = \frac{u_{i+\frac{2k-5} 2} - u_{i+\frac{2k-7} 2}}{\Delta x}.
+\end{equation}
+Otherwise if $u_{i+\frac 1 2}<0$, we calculate
+\begin{equation}
+  \Delta v_k = \frac{u_{i-\frac{2k-9} 2} - u_{i-\frac{2k-7} 2}}{\Delta x}.
+\end{equation}
+Next we calculate expressions for the smoothness of three substencils,
+\begin{align}
+  S_1 &= \frac{13}{12}(\Delta v_1 - 2\Delta v_2 + \Delta v_3)^2
+    + \frac 1 4 (\Delta v_1 - 4\Delta v_2 + 3\Delta v_3)^2, \\
+  S_2 &= \frac{13}{12}(\Delta v_2 - 2\Delta v_3 + \Delta v_4)^2
+    + \frac 1 4 (\Delta v_2 - \Delta v_4)^2, \\
+  S_3 &= \frac{13}{12}(\Delta v_3 - 2\Delta v_4 + \Delta v_5)^2
+    + \frac 1 4 (3\Delta v_3 - 4\Delta v_4 + \Delta v_5)^2,
+\end{align}
+where a small $S$ indicates a smooth substencil.  These smoothness factors are
+then used to compute weights for the substencils,
+\begin{equation}
+  w_k = \frac{b_k}{b_1+b_2+b_3},
+\end{equation}
+for $k = 1,2,3$, where
+\begin{equation}
+  b_1 = \frac 1 {10}\frac 1 {(\epsilon+S_1)^2},\quad
+  b_2 = \frac 6 {10}\frac 1 {(\epsilon+S_2)^2},\quad
+  b_3 = \frac 3 {10}\frac 1 {(\epsilon+S_3)^2}.
+\end{equation}
+Here $\epsilon$ is a regularization parameter that is used to avoid division by
+zero.  We have used $\epsilon = 10^{-6}$ in this work.  Finally, the WENO
+scheme for the gradient becomes
+\begin{multline}
+  \left. \pd u x \right|_{i+\frac 1 2} \simeq
+      w_1\left(\frac 1 3\Delta v_1 - \frac 7 6\Delta v_2
+        + \frac{11} 6 \Delta v_3\right) \\
+    + w_2\left(-\frac 1 6\Delta v_2 + \frac 5 6\Delta v_3
+        + \frac 1 3 \Delta v_4\right) \\
+    + w_3\left(\frac1 3\Delta v_3 + \frac 5 6\Delta v_4
+        - \frac 1 6 \Delta v_5\right).
+\end{multline}
+
+\subsection{The viscous term}
+The viscous term $\mu\lapl\vct u$ in the Navier-Stokes equations is discretized
+by standard second-order central differences using the ghost-fluid method
+(GFM)~\cite{Fedkiw99,Kang00,Liu00}.  This method includes the jump in the
+viscous term at the interface \eqref{eq:jumptens} in the discretization stencil
+in a sharp manner.
+
+In the following we present the GFM scheme in the one-dimensional case.  The
+extension to higher dimensions is straightforward.  In order to simplify the
+notation, we omit the half indices and let $k\equiv i+\frac 1 2$.  Further, we
+consider a general case where
+\begin{equation}
+  \jmp u = a_\Gamma, \qquad \jmp{\mu\pd u x} = b_\Gamma.
+\end{equation}
+For the viscous term, $a_\Gamma = 0$, cf.\ \eqref{eq:jmpu}, and $b_\Gamma$ is
+given by the jump tensor~\eqref{eq:jumptens}.  The jump tensor is calculated at
+the cell centres near the interface with the second-order central-difference
+scheme.  It is then interpolated linearly to the cell edges, from where it is
+again interpolated linearly to the interface when needed.
+
+If the interface does not cross the stencil, then the GFM scheme reduces to the
+standard second-order central-difference stencil.  Else there are four
+stencils, depending on the location of the interface.  One such interface
+configuration is sketched in \cref{fig:gfm-scheme-example}.  In all the
+stencils, $\theta$ is defined as the relative distance from the interface to
+the node on the left, for instance
+\begin{equation}
+  \theta = \frac{|\varphi_{k}|}{|\varphi_{k}| + |\varphi_{k+1}|},
+\end{equation}
+where $\varphi_k$ and $\varphi_{k+1}$ are the level-set function values
+linearly interpolated to the vector grid.  The four stencils are given below,
+where $h\equiv\Delta x$.
+\begin{enumerate}
+  \item Phase 1 is to the left and interface lies between $k$ and $k+1$:
+    \begin{align}
+      \begin{split}
+        \left.\pd{} x\left(\mu\pd u x\right)\right|_{x_k}
+          &= \frac{\hat\mu\left(u_{k+1} - u_{k}\right)
+                 - \mu_1\left(u_{k} - u_{k-1}\right)}{h^2} \\
+          &\qquad
+             - \frac{\hat\mu a_\Gamma}{h^2}
+             - \frac{\hat\mu b_\Gamma (1-\theta)}{\mu_2 h},
+      \end{split} \\

+          &= \frac{\mu_2\left(u_{k+1} - u_{k}\right)
+                - \hat\mu\left(u_{k} - u_{k-1}\right)}{h^2} \\
+          &\qquad
+            + \frac{\hat\mu a_\Gamma}{h^2}

+      \hat\mu &= \frac{\mu_1\mu_2}{\theta\mu_2 + (1-\theta)\mu_1}.
+    \end{align}
+  \item Phase 2 is to the left and interface lies between $k$ and $k+1$:
+    \begin{align}
+      \begin{split}
+        \left.\pd{} x\left(\mu\pd u x\right)\right|_{x_k}
+          &= \frac{\hat\mu\left(u_{k+1} - u_{k}\right)
+                - \mu_2\left(u_{k} - u_{k-1}\right)}{h^2} \\
+          &\qquad
+            + \frac{\hat\mu a_\Gamma}{h^2}
+            + \frac{\hat\mu b_\Gamma (1-\theta)}{\mu_1 h},
+      \end{split} \\
+      \hat\mu &= \frac{\mu_1\mu_2}{\theta\mu_1 + (1-\theta)\mu_2}.
+    \end{align}
+  \item Phase 2 is to the left and interface lies between $k-1$ and $k$:

+\subsection{Pressure Poisson equation}
+\label{sec:pressure-poisson}
+The Laplace operator in the Poisson equations \eqref{eq:PoissonDP1} and
+\eqref{eq:PoissonChorin} is also discretized by standard second-order central
+differences using the GFM~\cite{Kang00,Liu00}.  The GFM was discussed in the
+previous section, where stencils were given for the viscous term in the
+one-dimensional case.  For the pressure, the stencils are the same except we
+use $p$ instead of $u$, and $1/\rho$ and $1/\hat\rho$ instead of $\mu$ and
+$\hat\mu$.  To find the jump in the pressure at the interface, $\jmp
+p = a_\Gamma$, the jump condition \eqref{eq:jump_pressure} is calculated at the
+cell centres and then interpolated to the interface.  In addition, we use that
+$b_\Gamma = 0$, which is justified by \citet[Section~3.7]{Kang00}.
+
+The resulting linear system for the pressure is solved with a solver from the
+Portable, Extensible Toolkit for Scientific Computation (PETSc)~\cite{PETSc}.
+PETSc makes available a large selection of solvers.  In most cases, we used the
+direct solver based on LU factorisation or the conjugate gradient method with
+incomplete Cholesky factorisation.  In some cases, we used the GMRES solver
+with a preconditioner, either incomplete LU factorisation or an algebraic
+multigrid method.  See \cite{PETSc} for more details and a list of available
+methods, and see for example~\cite{Iserles09} or~\cite{Saad03} for an
+introduction to linear solvers.
+
+Finally, the gradient of the pressure, used in \eqref{eq:divFreeVel} and
+\eqref{eq:velcorrection}, is also calculated with the GFM.  In one dimension,
+the stencil is
+\begin{align}
+  \left. \frac 1 \rho \pd p x\right|_{i+\frac 1 2}
+           &= \frac 1 {\hat\rho} \frac{(p_{i+1} - a_\Gamma) - p_i} h, \\
+  \hat\rho &= \theta\rho_1 + (1-\theta)\rho_2,
+\end{align}
+if $\phi_i\leq 0$ and $\phi_{i+1}>0$, or else
+\begin{align}
+  \left. \frac 1 \rho \pd p x\right|_{i+\frac 1 2}
+           &= \frac 1 {\hat\rho} \frac{(p_{i+1} + a_\Gamma) - p_i} h, \\
+  \hat\rho &= \theta\rho_2 + (1-\theta)\rho_1,
+\end{align}
+where
+\begin{equation}
+  \theta = \frac{|\varphi_{i}|}{|\varphi_{i}| + |\varphi_{i+1}|}.
+\end{equation}
+
+\section{Temporal discretization}
+\label{sec:t-discr}
+The temporal discretization is done with the explicit strong
+stability-preserving Runge-Kutta (SSP-RK) schemes, see
+\cite{Ketcheson05,Shu88}.  The idea behind the SSP-RK schemes is to preserve
+the stability of a low-order method when it is extended to higher order.  It is
+argued in \cite{Gottlieb01} that if one extends the forward Euler method, which
+is total variation diminishing (TVD) for a suitable discretization of a scalar
+conservation law, to a non-SSP higher-order method, then overshoots may occur
+at discontinuities.
+
+An SSP-RK method can be written as a convex sum of explicit Euler steps with
+time step $\Delta t$,
+\begin{equation}
+  \mathcal E\left(x^n\right) = x^n + \Delta t \mathcal F(x^n,t^n).
+\end{equation}
+where $\mathcal F$ is the residual of the PDE to be solved.  In this thesis we
+have used two methods:  The third-order three-stage SSP-RK method~\cite{Shu88},
+\begin{equation}
+  \begin{split}
+    x^{(1)} &= \mathcal E\left(x^n\right), \\
+    x^{(2)} &= \frac 3 4 x^n + \frac 1 4\mathcal E\left(x^{(1)}\right), \\
+    x^{n+1} &= \frac 1 3 x^n + \frac 2 3\mathcal E\left(x^{(2)}\right),
+  \end{split}
+  \label{eq:ssprk33}
+\end{equation}
+and the third-order four-stage SSP-RK method~\cite{Kraaijevanger91},
+\begin{equation}
+  \begin{split}
+    x^{(1)} &= \frac 1 2 x^n + \frac 1 2\mathcal E\left(x^n\right), \\
+    x^{(2)} &= \frac 1 2 x^{(1)} + \frac 1 2\mathcal E\left(x^{(1)}\right), \\
+    x^{(3)} &= \frac 2 3 x^n + \frac 1 6 x^{(2)}
+               + \frac 1 6\mathcal E\left(x^{(2)}\right), \\
+    x^{n+1} &= \frac 1 2 x^{(3)} + \frac 1 2\mathcal E\left(x^{(3)}\right).
+  \end{split}
+  \label{eq:ssprk34}
+\end{equation}
+
+The semi-discretized velocity-extrapolation equation \eqref{eq:ls_velextr} and
+level-set reinitialization equation \eqref{eq:ls_reinit} can be written as
+systems of ordinary differential equations (ODEs) of the form
+\begin{equation}
+  \od{\vct \psi} \tau = \vct F(\vct\psi,\tau),
+\end{equation}
+where $\vct\psi$ is a vector containing the discrete variables and $\vct F$
+contains the spatially discretized terms.  The explicit Euler step becomes
+\begin{equation}
+  \mathcal E(\vct\psi^n) = \vct\psi^n + \Delta\tau \vct F(\vct\psi^n,\tau^n).
+\end{equation}
+In this thesis, these equations are solved with the third-order four-stage
+SSP-RK method \eqref{eq:ssprk34}.  The four-stage method is used because it is
+more accurate than the three-stage method.  We wanted to make sure that the
+error is mainly dominated by the spatial discretization.
+
+The semi-discretized Navier-Stokes equations \eqref{eq:navier-stokes-1} and
+\eqref{eq:navier-stokes-2} are solved together with the level-set advection
+equation \eqref{eq:ls_adeq} with the third-order three-stage SSP-RK method
+\eqref{eq:ssprk33}.  Here an explicit Euler step $\mathcal E(\vct
+u^n,\varphi^n)$ consists of the following steps:
+\begin{enumerate}
+  \item Calculate the curvature and the normal vectors from $\varphi^n$ with
+    one of the methods described in \cref{sec:curvature}.
+  \item Calculate the intermediate velocity field, either $\vct w$
+    \eqref{eq:continuousRightHandVector} or $\vct u^\star$ \eqref{eq:ustar}.
+  \item Solve the Poisson equation \eqref{eq:PoissonDP1} or
+    \eqref{eq:PoissonChorin} for the pressure as described in
+    \cref{sec:pressure-poisson}.
+  \item Correct the velocity field with either \eqref{eq:dp1-update} or
+    \eqref{eq:velcorrection}.
+  \item Advect the level-set function $\varphi^n$ with \eqref{eq:ls_adeq}.
+\end{enumerate}
+
+\section{Time step restriction}
+\label{sec:deltaT}
+We employ the Courant-Friedrich-Lewy~(CFL) condition to allow adaptive time
+stepping and to enforce stability.  The CFL condition that is used in this
+thesis is
+\begin{equation}
+  \Delta t = \frac{C}{\frac{C_c + C_v} 2
+             + \sqrt{(C_c + C_v)^2 + 4C_g^2 + 4C_s^2}},
+\end{equation}
+where the CFL restriction $C<1$, and $C_c$, $C_v$, $C_s$, and $C_g$ represent
+the contributions from the convective term, the viscous stresses, the surface
+tension, and the gravity, respectively,
+\begin{align}
+  C_c &=  \frac{\max_{i,j}|u_{i,j}|}{\Delta x}
+        + \frac{\max_{i,j}|v_{i,j}|}{\Delta y}, \\
+  C_v &= 2\max\left(\frac{\mu_1}{\rho_1},\frac{\mu_2}{\rho_2}\right)
+         \left(\frac{1}{\Delta x^2} + \frac{1}{\Delta y^2}\right), \\
+  C_s &= \sqrt{\frac{\sigma\max_{i,j}|\kappa_{i,j}|}
+                    {\max(\rho_1,\rho_2)\min(\Delta x^2,\Delta y^2)}}, \\
+  C_g &= \sqrt{\frac{|g_x|}{\Delta x} + \frac{|g_y|}{\Delta y}}.
+\end{align}
+This CFL condition is discussed in more detail by~\citet{Lervag08}, and it is
+based on the condition by \citet{Kang00}.
+
+\section{Axisymmetry}
+For axisymmetric flow, the governing equations \eqref{eq:ns1} and
+\eqref{eq:ns2} become
+\begin{equation}
+  \frac 1 r \pd{} r\left(r u\right) + \pd v z = 0,
+\end{equation}
+\begin{multline}
+  \rho\left(\pdt u + u\pd u r + v\pd u z\right) = -\pd p r \\
+    + \mu\left(\frac 1 r \pd{} r\left(r \pd u r\right)
+          + \pdd u z - \frac u {r^2}\right) + \rho f_r + {f_s}_r,
+\end{multline}
+and
+\begin{multline}
+  \rho\left(\pdt v + u\pd v r + v\pd v z\right) = -\pd p z \\
+    + \mu\left(\frac 1 r \pd{} r\left(r \pd v r\right)
+      + \pdd v z\right) + \rho f_z + {f_s}_z.
+\end{multline}
+Here $u$ and $v$ are the radial and axial velocity components, $f_r$ and $f_z$
+are the radial and axial body-force components, and ${f_s}_r$ and ${f_s}_z$ are
+the radial and axial components of the singular surface force, respectively.
+The equations are solved as explained in the previous sections.
+
+\section{Discretization of the curvature and the normal vector}
+\label{sec:curvature}
+As stated in \cref{sec:level-set}, the normal vector \eqref{eq:norm} and the
+curvature \eqref{eq:curv} can be calculated from the level-set function as
+\begin{align*}
+  \vct n &= \frac{\grad\varphi}{|\grad\varphi|}, \\
+  \kappa &= \div\left(\frac{\grad\varphi}{|\grad\varphi|}\right).
+\end{align*}
+They are typically discretized with the standard second-order
+central-difference scheme, cf.\ \cite{Kang00,Sethian03,Xu06}.  The normal
+vector is calculated at the cell edges, and the curvature is calculated at the
+grid nodes.  The curvature is then interpolated to the interface where needed
+with linear interpolation, for instance with
+\begin{equation}
+  \kappa_\Gamma = \frac{|\varphi_{i,j}|\kappa_{i+1,j}
+  + |\varphi_{i+1,k}|\kappa_{i,j}}{|\varphi_{i,j}| + |\varphi_{i+1,j}|}.
+  \label{eq:curvature-gamma}
+\end{equation}
+
+If the level-set method is used to capture non-trivial geometries, then it will
+contain kink regions, that is, areas where the gradient of the level-set
+function is discontinuous.  \Cref{fig:level-set-function} shows a simple
+example of such a kink region for a level-set function in a one-dimensional
+domain that captures two interfaces, one on each side of $x_i$.  The kink at
+$x_i$ may lead to large errors both for the curvature and the normal vector if
+one is not careful.  Errors in the curvature lead to errors in the surface
+tension force and in the pressure, which in turn lead to errors in the
+interface evolution and in the two-phase flow.  Errors in the normal vector
+affect both the calculation of the viscous jump condition and the advection of
+the interface.  If the level-set method is used to study for example
+coalescence and breakup of drops, these errors may severely affect the
+simulations.

+
+This problem was to our knowledge first described by \citet{Smereka03}, who
+increase the numerical smoothing in the curvature discretization to lessen the
+effect.  Several non-smearing approaches have subsequently been developed.
+\citet{Macklin05} used the level-set method to study tumor growth, and they
+present a one-sided direction-difference scheme for the discretization of the
+normal vector and the curvature.  Later, \citet{Macklin06} presented an
+improved geometry-aware curvature discretization, where the curvature is
+calculated based on a local least-squares parametrisation of the interface.
+
+A different approach to avoid the kinks was presented by \citet{Salac08}.  They
+used a level-set extraction technique, where an extraction algorithm was used
+to reconstruct separate level-set functions for each distinct \emph{body}.  The
+term \emph{body} is used here to denote a subset of a given phase or fluid.
+For example, in the case of two drops of water colliding in air, the water
+drops would make two distinct bodies.  One can also avoid the extraction
+algorithm altogether by use of multiple marker functions for different bodies,
+see for instance \cite{Coyajee09,Kwakkel12}.  Note, however, that the latter
+approach means that the different bodies will not coalesce unless explicit
+action is made, cf.~\cite{Kwakkel13}.  Also, both of the approaches mentioned
+here fails to handle the problem of kinks from a single body.  That is, there
+may still be kink areas due to deformed bodies, for instance bodies with thin
+filaments or tails, or bodies shaped like horse shoes.
+
+In the following, we first present the direction-difference
+scheme~\cite{Macklin05}.  We then describe the curve-fitting discretization
+method and the local level-set extraction method.
+
+\subsection{Direction-difference scheme}
+\label{sec:dds}
+The direction-difference scheme (DDS) was introduced by \citet{Macklin05}.  It
+uses a quality function to ensure that the difference stencils never cross any
+kink regions.  The DDS is used in Papers A--C to calculate the normal vectors.
+However, in Paper C it is shown that the DDS does not always yield an accurate
+approximation of the normal vector.
+
+The basic strategy is to use a combination of central differences and one-sided
+differences based on the values of a quality function,
+\begin{equation}
+  Q(\vct x) = \left| 1 - |\grad\varphi(\vct x)|\right|.
+  \label{eq:quality}
+\end{equation}
+The quality function is approximated with central differences, and is used to
+detect the areas where the level-set function differs from the signed-distance
+function.  In the following, let $Q_{i,j} \equiv Q(\vct x_{i,j})$ and define
+a parameter $\eta>0$.  This threshold parameter is tuned such that the quality
+function will detect all the kinks.
+
+The quality function is used to define a direction function,
+\begin{equation}
+  \vct D(\vct x_{i,j}) = (D_x(\vct x_{i,j}), D_y(\vct x_{i,j})),
+\end{equation}
+where
+\begin{equation}
+  D_x(\vct x_{i,j}) = \begin{cases}
+    -1 & \text{if $Q_{i-1,j}<\eta$ and $Q_{i+1,j}\geq\eta$,} \\
+     1 & \text{if $Q_{i-1,j}\geq\eta$ and $Q_{i+1,j}<\eta$,} \\
+     0 & \text{if $Q_{i-1,j}<\eta$ and $Q_{i,j}<\eta$ and $Q_{i+1,j}<\eta$,} \\
+     0 & \text{if $Q_{i-1,j}\geq\eta$ and $Q_{i,j}\geq\eta$ and
+         $Q_{i+1,j}\geq\eta$,} \\
+     4 & \text{otherwise.}
+  \end{cases}
+  \label{eq:dirfunc}
+\end{equation}
+$D_y(\vct x_{i,j})$ is defined in a similar manner.  If $D_x(\vct x_{i,j})
++ D_y(\vct x_{i,j}) > 2$, then $\vct D(\vct x_{i,j})$ is chosen as the vector
+normal to $\grad\varphi(\vct x_{i,j})$.  It is normalized, and the sign is
+chosen such that it points in the direction of the best quality.  See
+\cite{Macklin05} for more details.
+
+The DDS is then defined as
+\begin{equation}
+  \partial_x f_{i,j} = \begin{cases}
+    \frac{f_{i,j} - f_{i-1,j}}{\Delta x}    & \text{if $D_x(x_i,y_j) = -1$,} \\
+    \frac{f_{i+1,j} - f_{i,j}}{\Delta x}    & \text{if $D_x(x_i,y_j) =  1$,} \\
+    \frac{f_{i+1,j} - f_{i-1,j}}{2\Delta x} & \text{if $D_x(x_i,y_j) =  0$,}
+  \end{cases}
+  \label{eq:Ddifference}
+\end{equation}
+and similarly for $\partial_y f_{i,j}$, where $f_{i,j}$ is a piecewise smooth
+function.  The DDS is equivalent to using central differences in smooth areas
+and one-sided differences in areas close to the kinks.
+
+\subsection{Curve-fitting discretization method}
+\label{sec:curvature-curve-fitting}
+The curve-fitting discretization method (CFDM) was first presented
+in~\cite{Lervag11} and is based on the method by \citet{Macklin06}.  The main
+idea is to identify kink regions with the quality function \eqref{eq:quality},
+and to use a curve parametrisation of the closest interface to calculate the
+curvature in regions where the quality function is larger than the threshold
+parameter, $\eta$.
+
+The CFDM applied to the curvature or the normal vector at the grid point $\vct
+x_{i,j}$ can be summarized as follows.  See also \cref{fig:cfdm}, which shows
+an example of the CFDM used at $\vct x_{i,j}$.
+\begin{enumerate}
+  \item If the quality of the level-set function in the neighbourhood of $\vct
+    x_{i,j}$ is good, that is
+    \[
+      Q(\vct{x}_{n,m}) \le \eta \; \forall (n,m) \in [i-1,i+1]\times[j-1,j+1],
+    \]
+    then we use a standard discretization.  Otherwise continue to the next
+    step.
+  \item Locate the closest interface, $\Gamma$.
+  \item Find a set of points on the located interface, $\vct x_1, \dots, \vct
+    x_n \in \Gamma$.
+  \item Create a parametrisation $\vct \gamma(s)$ of the points $\vct x_1,
+    \dots, \vct x_n$.
+  \item Use the parametrisation $\vct \gamma(s)$ to calculate a local level-set
+    function.
+  \item Use a standard discretization of the local level-set function to
+    calculate the curvature or the normal vector.
+\end{enumerate}

+\subsection{Local level-set extraction method}
+\label{sec:lolex}
+The local level-set extraction (LOLEX) method is based on the method presented
+by \citet{Salac08}, here called the SLM.  It was found that the latter method
+was insufficient, because it did not treat all the kink problems.  The LOLEX
+method is therefore a further development of the SLM, in that it handles the
+kink regions in a more general manner.
+
+The LOLEX method applied to the curvature or the normal vector at a grid point
+$\vct x_{i,j}$ is summarized by the following algorithm.  The algorithm is
+presented with 2D notation for clarity, and extends easily to 3D.  See also
+\cref{fig:lolex}, which gives a simple example of the procedure.
+\begin{enumerate}
+  \item If the quality in the neighbourhood of $\vct x_{i,j}$ is good, that is
+    \[
+      Q(\vct{x}_{n,m}) \le \eta \; \forall (n,m) \in [i-1,i+1]\times[j-1,j+1],
+    \]
+    then we use a standard discretization.  Otherwise continue to the next
+    step.
+  \item Copy a small, local square centred around $\vct x_{i,j}$ from the
+    level-set function $\varphi$ into a local array $\varphi_\text{loc}$.
+  \item Identify and enumerate all the \emph{bodies} in the local array
+    $\varphi_\text{loc}$.  A \emph{body} is here defined as a set of
+    neighbouring points where $\varphi_\text{loc}<0$, see \cref{fig:lolex}.
+    There will be $n\geq 0$ bodies in any given $\varphi_\text{loc}$ array.
+  \item If no body is identified, that is, if $n=0$, then use a standard
+    discretization with the global level-set function $\varphi$.  Otherwise
+    continue to the next step.
+  \item For each body $n$, extract the relevant parts of $\varphi_\text{loc}$
+    into an array $\varphi_\text{loc}^n$.  If necessary, extrapolate values to
+    ghost cells.
+  \item For each body, $n$, reinitialize $\varphi_\text{loc}^n$.
+  \item At this step, all the bodies in the local grid have their own
+    local level-set functions that have been reinitialized to proper
+    signed-distance functions.  Due to the separation of the bodies, there
+    are no longer any kinks.
+  \item Use the standard discretization of the curvature and the normal
+    vector at the local level-set function that represents the body that is
+    closest to $\vct x_{i,j}$.

+\chapter{The diffuse-domain approach}
+\label{chap:diffuse-domain}
+In the previous chapters, we have considered the modelling of two-phase flows,
+and in particular methods for calculating the curvature and normal vector with
+the level-set method in a reliable manner.  In this chapter, we consider
+a different problem of a more general nature:  How to solve partial
+differential equations (PDEs) in complex domains.  In particular, we consider
+an extension of a diffuse-domain method (DDM) by a high-order correction term
+that gives increased accuracy with respect to interface-width refinements.
+
+We begin with a short introduction to the diffuse-domain approach.  We then
+outline how it can be used to derive a DDM for the steady reaction-diffusion
+equation with Neumann boundary conditions.  Next, we continue with a brief
+introduction to the method of matched asymptotic expansions.  Finally, we
+introduce the high-order correction term derived in Paper~E and show that the
+resulting DDM converge with second order in the diffuse-interface width to the
+original problem.  The analysis also shows that the correction term is not
+necessary for second-order convergence.
+
+\section{Introduction}
+There exist several methods for solving PDEs in complex domains.  Most of them
+have in common that they require tools or methods that are not frequently
+available in standard finite-element or finite-difference software packages.
+Examples of such methods include the immersed-interface method
+\cite{LeVeque94}, the matched interface and boundary method \cite{Zhou06}, the
+extended and composite finite-element method \cite{Dolbow09}, embedded boundary
+methods \cite{Johansen98}, cut-cell methods \cite{Ji06}, and ghost-fluid
+methods \cite{Fedkiw99}.  A different approach, known as the fictitious domain
+method~\cite{Glowinski94,Glowinski96} or the domain imbedding
+method~\cite{Buzbee71}, either augments the original system with equations for
+Lagrange multipliers to enforce the boundary conditions, or use the penalty
+method to enforce the boundary conditions weakly.  For a more complete list of
+references, see Paper~E.
+
+The DDM is an alternative method for solving PDEs in complex domains.  The main
+idea is to use an implicit representation of the boundary, where the sharp
+boundary is replaced by a diffuse layer.  The PDEs are then reformulated on
+a larger, regular domain, and the boundary conditions are incorporated via
+source terms in the diffuse layer.  When the thickness of the diffuse layer is
+reduced, these source terms tend towards singular source terms.  The resulting
+PDEs can then be solved with the use of standard tools and methods.
+
+The diffuse-domain approach was first introduced by \citet{Kockelkoren03} to
+study diffusion inside a cell with homogeneous Neumann boundary conditions at
+the cell boundary.  It was later used by \citet{Li09} to develop a DDM for
+solving PDEs in complex evolving domains with Dirichlet, Neumann and Robin
+boundary conditions, which is hereafter called the DDM1.  The DDM1 has been
+used by \citet{Teigen09-b}, who modelled bulk-surface coupling of material
+quantities on a deformable interface.  It was also used by \citet{Aland10} to
+simulate incompressible two-phase flows in complex domains in 2D and 3D, and by
+\citet{Teigen11} to study two-phase flows with soluble surfactants.
+
+An analysis of the error behaviour of the diffuse-domain approach was done by
+\citet{Franz12} for a diffuse-domain approximation of an elliptic problem with
+Dirichlet boundary conditions.  They considered the infinity norm of the
+difference of the approximated solution and the exact solution, and their
+analysis shows that the approximation quality is of order one in the interface
+width.
+
+In Paper~E, we present the DDM2, which is an extension of the DDM1 by
+a high-order correction term.  The DDM2 is derived for elliptic problems with
+Neumann and Robin boundary conditions, and it is shown to be asymptotically
+second-order accurate in the interface width.  However, the analysis in Paper~E
+is somewhat lacking in that it assumes that the DDM1 is only first-order
+accurate.  In the following sections, we extend the analysis of Paper~E and
+show that the DDM1 is also second-order accurate.  The analysis is shown for
+the steady reaction-diffusion equation with Neumann boundary conditions, but
+the same technique also applies for the corresponding Robin problem.
+
+\section{The DDM for a Neumann problem}
+Consider the steady reaction-diffusion equation with Neumann boundary
+conditions,
+\begin{equation}
+  \begin{alignedat}{2}
+    \lapl u - u  &= f        & \txin D, \\
+    \ndot\grad u &= g \qquad & \txon \partial D,
+  \end{alignedat}
+  \label{eq:ddan}
+\end{equation}
+where $f$ and $g$ are given.  Let $\chi_D$ be the characteristic function of
+$D$,
+\begin{equation}
+  \chi_D = \begin{cases}
+    1 & \text{if $x\in D$,} \\
+    0 & \text{if $x\notin D$.}
+  \end{cases}
+\end{equation}
+The main idea with the diffuse-domain approach is to extend the original
+equation \eqref{eq:ddan} into a larger and regular domain $\Omega\supset D$, as
+depicted in \cref{fig:ddadomain}.  The extension can be written as
+\begin{equation}
+  \div(\chi_D\grad u) - \chi_D u + \text{BC} = \chi_D f,
+  \label{eq:ddm}
+\end{equation}
+where BC is a singular source term that represents the physical boundary
+condition on $\partial\Omega$.

+The characteristic function is typically approximated by the phase-field
+function,
+\begin{equation}
+  \chi_D \simeq \phi(\vct x,t) = \frac{1}{2} \left( 1
+  - \tanh \left( \frac{3r(\vct x,t)}{\epsilon} \right) \right),
+  \label{eq:characteristic}
+\end{equation}
+where $\epsilon$ is the interface width and $r(\vct x,t)$ is the
+signed-distance function with respect to the boundary $\partial D$, which is
+taken to be negative inside $D$.
+
+The main difficulty with the diffuse-domain approach is the derivation of
+approximations for the boundary condition term BC.  \citet{Li09} give four
+approximations that are shown to converge asymptotically with first order in
+$\epsilon$ to the original equation when $\epsilon$ is decreased.  In the
+following we consider the approximation
+\begin{equation}
+  \text{BC} \simeq |\grad\phi| g.
+  \label{eq:bc1}
+\end{equation}
+If we combine the above approximations \eqref{eq:characteristic} and
+\eqref{eq:bc1}, we get a DDM1 equation for \eqref{eq:ddan},
+\begin{equation}
+  \div\left(\phi\grad u\right) - \phi u +  |\grad\phi| g = \phi f.

+\section{The method of matched asymptotic expansions}
+The following is a brief introduction to the method of matched asymptotic
+expansions, which is used to show that a given diffuse-domain approximation
+converges to the original problem when the interface width is decreased.  More
+details can be found in Paper~E and in \cite{Pego88}.
+
+Let $u$ be some diffuse-domain variable.  The asymptotic convergence of a given
+diffuse-domain approximation can be shown through expansions of the
+diffuse-domain variables in powers of the interface thickness $\epsilon$ in
+regions close to and far from the interface.  For example, the expansions of
+$u$ are
+\begin{align}
+  u(\vct x)        &= \sum_{k=0}^\infty \epsilon^k      u^{(k)}(\vct x), \\
+  \hat u(z,\vct s) &= \sum_{k=0}^\infty \epsilon^k \hat u^{(k)}(z,\vct s),
+\end{align}
+where $u(\vct x)$ and $\hat u(\vct s,z)$ denote the outer and inner expansions,
+respectively.  Here $z$ is a stretched variable,
+\begin{equation}
+  z = \frac{r(\vct x)}{\epsilon},
+\end{equation}
+where $r$ is the signed distance from the point $\vct x$ to $\partial D$ and is
+taken to be negative inside $D$.  Further, $z$ and $\vct s$ form a local
+coordinate system such that
+\begin{equation}
+  \vct x(\vct s,z) = \vct X(\vct s) + \epsilon z\vct n(\vct s),
+\end{equation}
+where $\vct X(\vct s)$ is a parametrisation of the interface, $\vct n(\vct s)$
+is the interface normal vector, and $z$ is a stretched variable.
+
+When the inner and outer expansions are found, they are matched in a region
+where both solutions are valid and where $\epsilon z = \bigo 1$, see
+\cref{fig:regions}.  The outer solution is then evaluated in the inner
+coordinates, which leads to a set of matching conditions that must hold when
+$\epsilon\to 0$.  If we consider $\epsilon$ to be fixed and let $z \to
+\pm\infty$, we get the following asymptotic matching conditions:
+\begin{equation}
+  \label{eq:match1}
+  \zlimpm \hat u^{(0)}(z,\vct s) = u^{(0)}(\vct s),
+\end{equation}
+and as $z \to \pm\infty$,
+\begin{align}
+  \label{eq:match2}
+  \hat u^{(1)}(z,\vct s) &= u^{(1)}(\vct s)
+    + z\ndot\grad u^{(0)}(\vct s) + \smallo 1, \\
+  \begin{split}
+    \hat u^{(2)}(z,\vct s) &= u^{(2)}(\vct s)
+      + z\ndot\grad u^{(1)}(\vct s) \\
+      &\quad + \frac{z^2}{2} (\ndot\grad)\grad u^{(0)}(\vct s)\cdot\vct n
+      + \smallo 1.
+    \label{eq:match3}

+\end{figure}
+
+We remark that the inner expansion is used to obtain the boundary condition on
+$\partial D$, and that the outer solution is used to obtain the sharp-interface
+equation inside the physical domain $D$.
+
+To show that a given DDM approximation converges with second order, one must
+show that the order-one term of the outer solution of the DDM equation is zero
+in $D$.  As an example, we consider the outer solution of the DDM1 equation
+\eqref{eq:ddm1}, which is
+\begin{equation}
+  \begin{split}
+    \lapl u^{(0)} - u^{(0)} &= f, \\
+    \lapl u^{(1)} - u^{(1)} &= 0, \\
+    \lapl u^{(k)} - u^{(k)} &= 0,\qquad k = 2,3,\dots.
+  \end{split}
+  \label{eq:ddm_outer}
+\end{equation}
+For the solution to be asymptotically second order, that is $u = u^{(0)}
++ \bigo{\epsilon^2}$, we must have that $u^{(0)}$ satisfies the original
+problem \eqref{eq:ddan} and that $u^{(1)}=0$.  Thus the inner expansion must
+yield a boundary condition for $u^{(1)}$ to enforce $u^{(1)}=0$.
+
+\section{Asymptotic analysis of the DDM1 and the DDM2}
+\label{sec:DDM2}
+In Paper~E we present the DDM2, which extends the DDM1 \eqref{eq:ddm1} with
+a high-order correction term,
+\begin{equation}
+  \div\left(\phi\grad u\right) - \phi u +  |\grad\phi| g
+    + r|\grad\phi|\left(f - \kappa  g - \lapls u + u\right) = \phi f.
+  \label{eq:ddm2}
+\end{equation}
+Here $r|\grad\phi|\left(f - \kappa  g - \lapls u + u\right)$ is the
+correction term, $\kappa$ is the curvature of the boundary $\partial D$, and
+$\lapls u$ is the surface Laplacian of $u$, which can be defined as
+\begin{equation}
+  \lapls u \equiv
+  \left( I - \vct n\otimes\vct n \right)
+        \div \left( I - \vct n\otimes\vct n \right)\grad u,
+\end{equation}
+where $I$ is the identity matrix and $\vct n$ is the normal vector.  The
+curvature can be calculated from the phase-field function
+\eqref{eq:characteristic} as
+\begin{equation}
+  \kappa = -\div\frac{\grad\phi}{|\grad\phi|}.
+\end{equation}
+
+In the following, we use the method of matched asymptotic expansions to show
+that the DDM1 \eqref{eq:ddm1} and the DDM2 \eqref{eq:ddm2} are both
+second-order approximations of \eqref{eq:ddan} in $\epsilon$.  First, it is
+easy to see that the outer expansions of both approximations are given by
+\eqref{eq:ddm_outer}.
+
+Next, we consider the inner expansion of the DDM2 \eqref{eq:ddm2}, which is
+\begin{multline}
+  \frac{1}{\epsilon^2}\left(\phi\hat u_z\right)_z
+  + \frac \kappa \epsilon \phi\hat u_z
+  + \phi\lapls \hat u
+  - \phi\hat u \\
+  - \frac 1 \epsilon \phi_z g
+  - z\phi_z\left(\hat u + \hat f - \kappa g - \lapls\hat u\right)
+  = \phi \hat f.
+  \label{eq:ddm_inner}
+\end{multline}
+We expand $\hat u(z,\vct s)$ in powers of $\epsilon$ and collect the lowest
+order terms,
+\begin{equation}
+  \left(\phi\hat u_z^{(0)}\right)_z = 0.
+\end{equation}
+If we integrate over all $z$, we get that $\hat u_z^{(0)} = 0$.  The next order
+terms of~\eqref{eq:ddm_inner} then give
+\begin{equation}
+  \left(\phi\hat u_z^{(1)}\right)_z = \phi_z g,
+\end{equation}
+and again we integrate, which gives that
+\begin{equation}
+  \phi\hat u_z^{(1)} = \phi g + C
+  \label{eq:uz1}
+\end{equation}
+where the constant $C$ must be zero, since $\lim_{z\to\infty}\phi(z) = 0$.  Now
+consider the limit $z\to-\infty$ and use the matching condition
+\eqref{eq:match2} to get
+\begin{equation}
+  \ndot\grad u^{(0)} = g.
+\end{equation}
+Thus $u^{(0)}$ satisfies the original problem at least to first order in
+$\epsilon$.  This shows that both DDM1 and DDM2 are first-order approximations
+of the sharp-interface problem.
+
+To obtain the result for the next order, we need to apply the derivative of
+the matching condition \eqref{eq:match3},
+\begin{equation}
+  \hat u_z^{(2)} = \ndot\grad u^{(1)}
+      + z (\ndot\grad)\grad u^{(0)}\cdot\vct n.
+  \label{eq:match3_z}
+\end{equation}
+Further, we use that $u^{(0)}$ satisfies
+\begin{equation}
+  \lapl u^{(0)} - u^{(0)} = f^{(0)},
+\end{equation}
+and that the Laplacian may be decomposed as
+\begin{equation}
+  \lapl u = (\ndot\grad)\grad u\cdot\vct n + \kappa\ndot\grad u + \lapls u,
+\end{equation}
+to get
+\begin{equation}
+  (\ndot\grad)\grad u^{(0)}\cdot\vct n
+    = u^{(0)} + f^{(0)} - \kappa g - \lapls u^{(0)}.
+  \label{eq:ngradun}
+\end{equation}
+Now insert \eqref{eq:ngradun} into \eqref{eq:match3_z} and use the matching
+condition \eqref{eq:match1} to obtain a modified matching condition,
+\begin{equation}
+  \hat u_z^{(2)} - z\left(\hat u^{(0)} + \hat f^{(0)}
+        - \kappa g - \lapls \hat u^{(0)}\right)
+  = \ndot\grad u^{(1)}.
+  \label{eq:match3_z2}
+\end{equation}
+
+We are now ready to consider the zeroth order terms,
+\begin{multline}
+  \label{eq:o1}
+  \left(\phi\hat u^{(2)}_z\right)_z
+  + \phi\kappa\hat u_z^{(1)}
+  + \phi\lapls \hat u^{(0)}
+  - \phi\hat u^{(0)} \\
+  - z\phi_z\left(\hat u^{(0)}
+      + \hat f^{(0)} - \kappa g - \lapls\hat u^{(0)}\right)
+  = \phi \hat f^{(0)}.
+\end{multline}
+The modified matching condition \eqref{eq:match3_z2} motivates that we subtract
+and add the term
+\[
+  \bigg(z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\bigg)_z
+\]
+to \eqref{eq:o1}, which gives
+\begin{multline}
+  \bigg(\phi\hat u_z^{(2)}
+    - z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\bigg)_z \\
+  + \bigg(z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\bigg)_z \\
+  + \phi\kappa\hat u_z^{(1)}
+  + \phi\lapls \hat u^{(0)}
+  - \phi\hat u^{(0)} \\
+  - z\phi_z\left(\hat u^{(0)}
+      + \hat f^{(0)} - \kappa g - \lapls\hat u^{(0)}\right)
+  = \phi \hat f^{(0)}.
+\end{multline}
+We expand the terms and use \eqref{eq:uz1},
+\begin{multline}
+  \bigg(\phi\hat u_z^{(2)}
+    - z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\bigg)_z \\
+  + \cancel{\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)} \\
+  + z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)_z \\
+  + \cancel{\phi\kappa g
+  + \phi\lapls \hat u^{(0)}
+  - \phi\hat u^{(0)}}
+  = \cancel{\phi \hat f^{(0)}},
+  \label{eq:o2}
+\end{multline}
+or
+\begin{multline}
+  \bigg(\phi\hat u_z^{(2)}
+    - z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\bigg)_z \\
+  + z\phi\left(\cancel{\hat u_z^{(0)}} + \hat f_z^{(0)}
+      - \cancel{(\kappa g)_z}
+      - \cancel{\lapls \hat u_z^{(0)}}\right) = 0.
+\end{multline}
+If we assume that $\hat f_z^{(0)}$, we get
+\begin{equation}
+  \bigg(\phi\hat u_z^{(2)}
+    - z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\bigg)_z = 0.
+  \label{eq:o3}
+\end{equation}
+Finally, we integrate the left-hand side and take the limit,
+\begin{align}
+  \nonumber
+  \eint{\bigg(\phi\hat u_z^{(2)}
+    &- z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+     - \lapls \hat u^{(0)}\right)\bigg)_z} \\
+  \nonumber
+  &= \ejmp{\phi\hat u_z^{(2)}
+    - z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)} \\
+  \nonumber
+  &= -\zlimm{\left(\hat u_z^{(2)}
+    - z\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\right)} \\
+  &= -\ndot\grad u^{(1)},
+\end{align}
+thus
+\begin{equation}
+  \ndot\grad u^{(1)} = 0.
+  \label{eq:ngradu1}
+\end{equation}
+Combined with \eqref{eq:ddm_outer}, this shows that $u^{(1)}=0$, and so DDM2
+converges asymptotically with second order to the original problem.
+
+The analysis above also holds for DDM1, except instead of \eqref{eq:o3} we get
+\begin{multline}
+  \bigg(\phi\hat u_z^{(2)}
+    - z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\bigg)_z \\
+  = - z\phi_z \left(\hat u^{(0)} + \hat
+        f^{(0)} - \kappa g - \lapls \hat u^{(0)}\right)
+  = - z\phi_z D,
+  \label{eq:o4}
+\end{multline}
+where $D$ is independent of $z$.  Now we use that
+\begin{equation}
+  \phi_z = -(3 \sech^2 3z)/2,
+\end{equation}
+which follows from the definition of the phase-field function
+\eqref{eq:characteristic}.  We integrate the right-hand side, which gives
+\begin{equation}
+  D\eint{z\phi_z} = -D\frac 3 2\eint{z\sech^2 3z} = 0.
+\end{equation}
+Thus DDM1 is also second order in $\epsilon$.
+
+The difference between the DDM1 and the DDM2 is therefore that the correction
+term with the DDM2 directly cancels the term on the right-hand side in
+\eqref{eq:o4}.  This should give an increase of accuracy, but the convergence
+order remains the same.
+
+The analysis for the corresponding Robin problem is essentially the same as the
+above.  In Paper~E, the DDM1 and DDM2 are compared for several elliptic
+problems with both Neumann and Robin boundary conditions.  The results of
+Paper~E show that the correction term in the DDM2 leads to an increase of
+accuracy and that both DDM1 and DDM2 converge with second-order accuracy.
+
+\section{Summary}
+In this chapter, we have given a brief introduction to the diffuse-domain
+method (DDM).  We considered a steady reaction-diffusion equation with Neumann
+boundary conditions \eqref{eq:ddan} and two DDM approximations:  DDM1
+\eqref{eq:ddm1} and DDM2 \eqref{eq:ddm2}.  The DDM2 is an extension of DDM1 by
+a high-order correction term, and was first derived in Paper~E.
+
+Next, we gave an outline of the method of matched asymptotic expansions, and we
+used it to show that both the DDM1 and the DDM2 converged asymptotically with
+second order in the diffuse-interface width to the original equation
+\eqref{eq:ddan}.  The analysis shows that the correction term in the DDM2 leads
+to a cancellation in the asymptotic expansions.  By doing the integration, we
+see that this cancellation is not necessary for obtaining the second order
+convergence.

+\section[Paper A]{Paper A:  Calculation of interface curvature with the
+  level-set method}
+Karl Yngve Lervåg.  Published in \emph{MekIT'11 - 6th National Conference on
+  Computational Mechanics, Trondheim}, 2011.  ISBN: 978-82-519-2798-7.
+
+In this paper I address a problem with the calculation of the interface
+curvature with the level-set method, cf.\ \cref{sec:curvature}.  The curvature
+can be calculated from the level-set function, $\phi$, as
+\begin{equation}
+  \kappa = \div\vct n = \div\frac{\grad\phi}{|\grad\phi|}.
+\end{equation}
+It is typically discretized by standard methods such as the second-order
+central-difference scheme (CD-2), and interpolated to the interface where
+needed \cite{Osher88,Kang00,Osher03}.  However, the level-set function as
+a signed-distance function will tend to have kinks where its gradient is
+discontinuous.  The standard methods may lead to large errors in the curvature
+close to these regions, which in turn may lead to errors in the surface tension
+force.
+
+The main contribution of this paper is a new curve-fitting discretization
+method (CFDM) for the curvature (see \cref{sec:curvature-curve-fitting}).  The
+method is based on the approach developed by \citet{Macklin06}.  It differs in
+that it uses a cubic Hermite spline parametrisation of the interface, and that
+the curvature values are calculated on the grid and then interpolated to the
+interface as opposed to using a localised grid centred at the interface as in
+\cite{Macklin06}.

+Karl Yngve Lervåg and Åsmund Ervik.  Published in \emph{ENUMATH 2011}
+proceedings volume, Springer, 2013.  ISBN: 978-3642331336.
+
+This paper is a continuation of Paper A.  The main contribution in this paper
+is a comparison of different methods for calculating the curvature in a robust
+manner with the level-set method in the kink regions.  In particular, the
+CFDM\footnote{The method is called LM in the paper.  Here CFDM is used, in
+  order to be consistent with the rest of the thesis.} that was presented in
+Paper A is compared with Macklin and Lowengrub's method (MLM)~\cite{Macklin06}.
+In addition, the method is compared with the second-order central-difference
+scheme (CD-2) and the more recent method presented by \citet{Salac08}, here
+called Salac and Lu's method (SLM).
+
+The main result in the paper is shown in \cref{fig:B1}, which shows
+a comparison of the methods for a case where two drops collide in a 2D shear
+flow.  In particular, it shows snapshots of the evolution of the interfaces and
+the curvature at times $t=\SI{2.30}{s}$, $t=\SI{2.75}{s}$, and
+$t=\SI{3.10}{s}$.  The results show that all of the improved methods, that is
+MLM, CFDM, and SLM, handle the kink region in a more reliable manner than CD-2.
+The reason that the result with MLM differs from those with CFDM and SLM might
+be that it uses a localised grid centred at the interface to calculate the
+curvature, which means that it does not need to use interpolation of the
+curvature from the grid to the interface.  Note that the difference is mainly
+that the MLM results in slightly earlier coalescence in the given case.

+\section[Paper C]{Paper C:  Calculation of the interface curvature and normal
+  vector with the level-set method}
+Karl Yngve Lervåg, Bernhard Müller, and Svend Tollak Munkejord.  Published in
+Computers and Fluids, volume 84 (2013), 218--230.
+
+Paper A presented the curve-fitting discretization method (CFDM) for the
+calculation of the curvature with the level-set method.  The method was
+designed to be robust in the calculation of the curvature in kink regions, that
+is regions where the gradient of the level-set function is not smooth.  This
+paper presents the details of the CFDM and applies it to the calculation of
+both the curvature and the normal vector.
+
+In the paper we compare the CFDM with the second-order central-difference
+scheme (CD-2) for several test cases.  In the first case, we consider the
+curvature calculations for a nontrivial geometry that includes some kink
+regions.  This is a static test case with no flow, and the results show that
+the CD-2 leads to large errors for the curvature calculations in areas close to
+kink regions and that these errors are not present with the CFDM.
+
+In the following two cases, we consider the collision of two drops in a 2D
+shear flow and in an axisymmetric flow.  These cases show that the errors in
+the curvature calculations in the kink regions with the CD-2 lead to errors in
+the pressure that prevents coalescence.  These errors are prevented with the
+CFDM.  The curvature and the evolution of the interfaces for the axisymmetric
+case are shown in \cref{fig:C1,fig:C2}.  As in the earlier results of Papers
+A and B, the figures show that the errors in the curvature calculation with
+CD-2 prevent coalescence, in this case leading to a slower coalescence process.

+\section[Paper D]{Paper D:  A robust method for calculating interface curvature
+  and normal vectors using an extracted local level set}
+Åsmund Ervik, Karl Yngve Lervåg, and Svend Tollak Munkejord.  Submitted to
+Journal of Computational Physics, 2013.
+
+In this paper we present an alternative method for the calculation of the
+curvature and the normal vector of an interface with the level-set method in
+kink regions, hereafter called the local level-set extraction (LOLEX) method.
+The method is based on a method presented by \citet{Salac08} (SLM), who handle
+the kink region by extracting different bodies of a domain into separate
+level-set functions.  This procedure removes most of the kink regions, but it
+does not handle kink regions that are due to complex interfaces of single
+bodies.  Our method extends the SLM by making it local.  That is, we only
+consider the local area around the point for which we are calculating the
+curvature or the normal vector.  This leads to a method that is more generally
+applicable, as shown in \cref{fig:D1}.  The figure shows a comparison between
+the LOLEX method, the SLM, and the standard central differences (CD-2).  CD-2
+leads to curvature spikes at the kink regions, as explained in
+\cref{sec:curvature}.  The SLM gives a better result for the kink regions
+around the rightmost disc.  However, since the other two discs are connected to
+each other and to the film, they are considered to be the same body and are
+extracted into the same level-set function.  Several kink regions are therefore
+not removed.  Since the LOLEX method only considers the local area, as
+explained in \cref{sec:lolex}, it is able to handle all the kink regions in
+a robust manner.

+    negative and red is positive.}
+  \label{fig:D1}
+\end{figure}
+
+The LOLEX method has proven to be a good alternative to the CFDM presented in
+Paper A.  Its main advantages are that it does not rely on complex algorithms
+as used in the CFDM or by \citet{Macklin06}, and that the method easily extends
+to 3D as demonstrated in the paper in Section~4.4.
+
+In the previous papers A--C, we used the DP1 projection method by
+\citet{Hansen05}.  In this paper we instead used the more standard Chorin
+projection method.  These methods differ in that the DP1 assumes
+\begin{equation}
+  \div\left(\pdt{\vct u}\right) = 0.
+\end{equation}
+When compared with the Chorin method, this assumption becomes equivalent to
+assuming that $\div\vct u^{n} = 0$ in \eqref{eq:PoissonChorin}.  That is, the
+DP1 assumes that the initial velocity field is divergence free.  We have found
+that the DP1 works well in most cases, but that it is less robust than the
+Chorin method.  In particular, the Chorin method is not equally affected by
+errors in the curvature calculations in kink regions.  In other words, the
+difference between using a standard discretization and an improved
+discretization of the curvature is smaller with the Chorin method than with the
+DP1.
+
+The LOLEX method is used for several test cases and compared with CD-2.  The
+results indicate that even though we use the Chorin projection method, the
+LOLEX method outperforms CD-2 in all cases.  Further, the results agree well
+with experiments, except for time instants, as shown in \cref{fig:D2}.  The
+exact reason why the time instants do not match is not known, but one reason
+may be that the initial condition of the numerical simulation did not match the
+corresponding state of the experiment.

+\end{figure}
+
+When we study the drop-film collision processes, an important consequence of
+the error in the curvature calculation is a loss of kinetic energy.  This can
+be seen in \cref{fig:D3}, which compares the LOLEX method with CD-2 at two
+different stages of the collision process.  The figure also compares two
+different frequencies of reinitialization of the level-set function:  Every
+7 time steps ((a) and (c)) and every single time step ((b) and (d)).  The
+figure shows that the error in the curvature calculation with CD-2 leads to
+a shorter neck, as seen in \cref{fig:D3}, (c) and (d).  The error is larger for
+the higher frequency of reinitialization.  The results indicate that CD-2 leads
+to a loss of kinetic energy during the collision process when compared with the
+LOLEX method.  The LOLEX method is not significantly affected by the amount of
+reinitialization, and the kink region does not affect the curvature
+calculation, cf.\ \cref{sec:lolex}.  Thus the pressure field is more sensible,
+as seen in \cref{fig:D3} (a) and (b).  Finally, we remark that some authors
+have noted \cite{Blanchette06} that the height of the neck and the dynamics of
+the capillary waves are important factors for the partial coalescence
+mechanism, which implies that the correct calculation of the curvature is
+important to capture the correct physical behavior.

+\section[Paper E]{Paper E:  Towards a second-order diffuse-domain approach for
+  solving PDEs in complex geometries}
+Karl Yngve Lervåg and John Lowengrub.  Submitted to Communications in Math.
+Sciences, 2013.
+
+\citet{Li09} developed a diffuse-domain method for solving partial-differential
+equations (PDEs) inside complex, dynamic geometries with Dirichlet, Neumann,
+and Robin boundary conditions.  This method is in the following referred to as
+DDM1.  They use the diffuse-domain approach~\cite{Kockelkoren03}, where the
+geometry is represented implicitly and the sharp boundary is replaced by
+a diffuse layer with a fixed interface width.  The original governing equations
+are then reformulated on a larger, regular domain and the boundary conditions
+are incorporated via singular source terms.  The method of matched asymptotic
+expansions is used to show that the reformulated problem converges
+asymptotically to the original problem.
+
+In the present paper, we use the method of matched asymptotic expansions to
+extend the DDM1 with include a high-order correction term in the diffuse
+formulation, cf.\ \cref{sec:DDM2}.  The extension is derived for elliptic
+problems with Neumann and Robin boundary conditions, where the correction term
+is shown to yield an asymptotically second-order accurate approximation of the
+original problem.  The new method is referred to as the DDM2.
+
+The DDM1 and DDM2 are compared for a selection of test problems.  The resulting
+equations were discretized by standard second-order central-difference schemes
+on uniform grids, and solved by a multigrid method.  A red-black Gauss-Seidel
+type iterative method was used as a smoother, see \cite{Wise07}.
+
+In addition to the comparison of DDM1 and DDM2, we compared two different
+approximations of the boundary conditions.  These correspond to different
+diffuse-interface surface delta functions, and for the Neumann boundary
+conditions they are
+\begin{equation}
+  \text{BC1} = |\grad\phi| g,
+\end{equation}
+and
+\begin{equation}
+  \text{BC2} = \epsilon|\grad\phi|^2 g.
+\end{equation}
+The approximations are similar for the Robin boundary condition, although here
+it was found that only BC1 resulted in a valid asymptotically second-order
+accurate DDM2.
+
+Our results show that the global accuracy and convergence of DDM2 is better
+than DDM1, however both methods perform well and the global convergence rate is
+around two for each.  The error was measured as the L$_2$ norm of the
+difference between an analytic solution and the solution $u_\epsilon$ for
+a given interface width, $\epsilon$.
+
+\Cref{fig:E1,fig:E2} show two of the results, the first one with the Neumann
+boundary conditions and the second with the Robin boundary condition.  The
+results indicate that DDM2 performs slightly better than DDM1.  They also show
+that the approximation BC1 gives more accurate results than BC2.  In
+particular, we found that with BC2 we needed much finer grids to obtain
+convergence for a given $\epsilon$.  For the smallest values of $\epsilon$ we
+were not able to refine the grids enough to obtain valid results.

+\chapter{Conclusions and outlook}
+\label{chap:conclusions}
+This thesis has considered two different problems:  The discretization of
+interface curvature and normal vectors with the level-set method and
+a diffuse-domain approach for solving partial-differential equations (PDEs) in
+complex domains.  In the following, some general concluding remarks and
+recommendations for further work are given.
+
+\section*{Conclusions}
+The first part of the thesis considered the modelling of incompressible
+two-phase flow.  The main motivation was to study two-phase flow phenomena that
+are relevant for compact heat exchangers, such as drop-drop and drop-film
+collisions.  In particular, the thesis addressed a challenge with the
+calculation of interface curvature and normal vectors with the level-set
+method.  Two methods were presented to handle the discretization in the kink
+regions: A curve-fitting discretization method (CFDM) and a local level-set
+extraction (LOLEX) method.  Both methods were shown to be robust in the kink
+regions, where the standard central-difference scheme (CD-2) fails.  Of these
+methods, the LOLEX method is the preferred method, because it relies on a less
+complicated algorithm that easily extends to 3D.
+
+CD-2 and the LOLEX method were used for simulations of drop-film collisions
+that were compared with experiments.  The results showed that CD-2 leads to
+errors in the curvature that cause unphysical pressure spikes during the
+coalescence.  The errors are shown to lead to a dissipation of kinetic energy
+during the collision and to a slower coalescence process.  The LOLEX method was
+shown to prevent these unphysical pressure spikes, and to produce to more
+accurate results.
+
+The second part of the thesis considered the diffuse-domain approach for
+solving PDEs in complex domains.  The main contribution, presented in Paper~E,
+was the derivation of an asymptotically second-order diffuse-domain method
+(DDM2) for solving elliptic problems in complex geometries with Neumann and
+Robin boundary conditions.  The new method is an extension by a high-order
+correction term of the method presented in \cite{Li09}, here called DDM1.  The
+DDM1 and DDM2 were compared, and the results indicated that the DDM2 was
+slightly better than the DDM1.
+
+The thesis has expanded on the results of Paper~E with a new asymptotic
+analysis that shows that DDM1 is in fact also asymptotically second order.
+This analysis helps to explain why the performance of DDM2 presented in Paper~E
+is only slightly better than that of DDM1.  As such, the new analysis leads to
+a better understanding of the DDM1 and the DDM2.
+
+\section*{Outlook}
+The following gives an outline of some possibilities for future work.
+\begin{itemize}
+  \item A natural continuation of this work is to perform more in-depth
+    comparisons of simulations with experiments for the drop-film collision
+    phenomenon that was started in Paper~D.  In addition, it would be
+    interesting to study other two-phase flow phenomena that are relevant for
+    heat-exchanger processes, for instance drop-drop collisions or flow across
+    tube bundles.  The latter requires the treatment of more complex boundaries,
+    which can be handled either with the diffuse-domain method or other methods
+    from the literature.
+  \item Paper~C gave a short comparison of the standard discretization method
+    (CD-2), the direction-difference scheme (DDS), and the curve-fitting
+    discretization scheme (CFDM) applied to the calculation of the normal
+    vectors.  The results showed that the CD-2 leads to inaccurate results in
+    the kink regions.  The DDS gives robust and accurate results in most cases,
+    but an example is given where only the CFDM yields an accurate result.
+    However, the impact of inaccurate calculations of the normal vector should
+    be investigated in more detail.  The normal vector is used both for the
+    solution of the level-set equations \eqref{eq:ls_adeq},
+    \eqref{eq:ls_velextr}, and \eqref{eq:ls_reinit}, and for the calculation of
+    the interface jumps \eqref{eq:jump_pressure} and \eqref{eq:jumptens}, so
+    one can expect that large errors in the calculation of the normal vector
+    may lead to large errors in the numerical solution.  This warrants
+    a further study.
+  \item Mass and heat transfer are obviously an important part of the
+    heat-exchanger processes.  The models that have been used in this thesis
+    should therefore be expanded with additional models for heat transfer and
+    mass transfer to enable the simulation of more relevant phenomena.
+  \item The DDM2 was only derived for problems with Robin and Neumann boundary
+    conditions.  If possible, it should be extended to also work with Dirichlet
+    boundary conditions.
+  \item As explained in Paper~E, we found that we were unable to solve the
+    discrete system of equations when the surface Laplacian part of the
+    correction term for the DDM2 was included.  A further investigation of this
+    problem should be done, and stable numerical methods to solve the full DDM2
+    equations should be developed.
+  \item The diffuse-domain approach is a promising method for solving problems
+    in complex and confined geometries with standard tools and methods.
+    \citet{Aland10} provide a diffuse-domain formulation of the Navier-Stokes
+    Cahn-Hilliard equations for incompressible two-phase flow and use it to
+    compute two-phase flow in both complex and confined geometries.  However,
+    they do not provide an asymptotic analysis of the reformulated equations to
+    show that the system converges.  Such an analysis would be interesting, in
+    particular to verify that the equations do converge to the original problem
+    when the interface width is decreased.
+  \item Finally, it would be interesting to develop a second-order
+    diffuse-domain formulation for the incompressible Navier-Stokes equations.
+    A starting point would be to use the results and techniques from this
+    thesis and Paper~E.

+\chapter{Introduction}
+This thesis considers the mathematical modelling and numerical computation of
+two-phase flows.  It focuses on developing more robust numerical methods to
+calculate the curvature and the normal vector of the interface between the two
+phases.  In addition it considers a diffuse-domain method for solving partial
+differential equations in complex geometries, and it derives an asymptotically
+second-order method for elliptic problems.
+
+\section{Background and motivation}
+Two-phase flows are particular examples of multiphase flows of gas and liquid
+with an interface that separates the two phases.  In the pedantic sense,
+two-phase flow is flow of a single fluid that occurs as two different phases,
+for example steam and water.  However, it is common to be more general, and in
+this thesis we use the term two-phase flow also for immiscible mixtures of
+different fluids, such as water and oil.
+
+Two-phase flows are crucial to a large amount of processes, both in nature and
+in industry.  Examples range from weather phenomena, such as rain drops falling
+through air, to industrial processes, for instance the separation of water from
+oil.  In general, multiphase flow phenomena influence any process where liquids
+and gases are involved.  In the oil and gas industry, most processes are
+two-phase or multiphase flow processes.  Needless to say, the understanding of
+these phenomena is fundamental in the development of new or improved processes.
+
+Consider the international trade of liquefied natural gas (LNG), which is
+a particular branch of the oil and gas industry that has undergone an
+exceptional growth in the last decades.  There is a strong focus both in Norway
+and internationally on producing LNG on large floaters
+(FLNG)\footnote{FLNG facilities do not yet exist, although a facility is under
+  development by Royal Dutch Shell~\cite{Prelude1}.  The construction of this
+  facility was started in 2012, and the first drilling is stated to commence in
+  2013~\cite{Prelude2}.}.  There are a number of both environmental and
+economic advantages of such FLNG facilities.  In particular, FLNG facilities
+would remove the need of long pipelines from the gas fields to the shore, there
+would be no requirement for compression units to pump the gas to the shore, and
+one would not need to construct onshore production facilities.  This would
+significantly reduce the environmental footprint, and would help preserve
+marine and coastal environments.  Since an FLNG facility can be moved to a new
+location when a field has been depleted, it would make it economically viable
+to open up new business opportunities to develop offshore gas fields that would
+otherwise remain stranded.
+
+Moving the LNG production to an offshore facility presents a demanding set of
+challenges.  A particular challenge is that the elements of a conventional LNG
+facility need to fit into an area roughly one quarter the original size.  Heat
+exchangers are among the main challenges in the design and operation of LNG
+plants \cite{Hesselgreaves01}.  Compact and efficient heat exchangers are
+needed to obtain an energy efficient plant with low emissions.  More optimized
+designs require more accurate tools for design and operation.  Such tools can
+only come as a result of an improved physical understanding of the complex
+two-phase flows occurring in the heat exchangers.  This can be achieved by more
+detailed mathematical modelling, together with dedicated laboratory
+observations, cf.\ \cite{Olsen07}.
+
+\section{Overview of methods for two-phase flow simulations}
+In the following, a brief overview is given of different methods for modelling
+two-phase flows where the interface location is known.  In particular, we focus
+on methods that handle the interface evolution.  For more in-depth reviews, see
+for instance \cite{Cristini04,Scardovelli99,Sethian03}.
+
+Interface propagation methods comprise a range of methods that are often
+categorised as either front tracking or front capturing.  Front-tracking
+methods use Lagrangian particles to track the interface
+explicitly~\cite{Tryggvason01}, while front-capturing methods use an Eulerian
+approach to capture the interface implicitly.  Examples of the latter are
+volume-of-fluid methods~\cite{Scardovelli99,Tryggvason11}, phase-field
+methods~\cite{Anderson98,Jacqmin99,Lowengrub98}, and level-set
+methods~\cite{Osher03}.
+
+The main advantages of front-tracking methods are their inherent accuracy and
+that topological changes do not occur without explicit action.  Hence,
+unphysical numerical reconnection does not occur.  This means that if front
+tracking is used for the simulations of two drops that collide, these drops
+will not coalesce due to numerical reconnection or merging.  However, the
+handling of topological changes are challenging, in particular in three
+dimensions~\cite{Shin02}.  Also, there are some issues of numerical
+instabilities, as discussed by \citet{Sethian85} and \citet{Osher88}.
+
+The volume-of-fluid method utilizes a volume-fraction function whose values
+represent the characteristic function of one of the fluid domains.  Its values
+are zero or one, except in those cells cut by the interface.  A considerable
+advantage of the volume-of-fluid method is that it conserves the mass of both
+fluids well.  However, the reconstruction of the interface from volume
+fractions is not simple, and computation of geometric quantities such as the
+interface curvature is not straightforward.  Also, spurious bubbles and drops
+may be created, cf.\ \cite{Lafaurie94}.
+
+The phase-field methods treat the interface in a diffuse manner, where the
+fluid properties, such as density and viscosity, change rapidly but smoothly
+across the interface.  These methods typically solve the coupled
+Cahn-Hilliard/Navier-Stokes equations, where the Cahn-Hilliard equation is
+based on the free energy of an interface~\cite{Cahn57}.  Through this energy
+formulation, one can model more advanced interface physics such as van der
+Waals interactions, electrostatic forces, and fluids with varying
+miscibilities.  However, the phase-field methods require that one resolves very
+small length scales at the interfaces.  This poses a severe restriction on the
+applicability of phase-field methods for two-phase flow, where the length
+scales of the flow are generally much larger than those of the interface.
+
+In this thesis, we have used the level-set method~\cite{Osher88}, which
+implicitly captures the interface as an isocontour of a function defined in the
+entire domain.  The main motivation of this choice is both that the level-set
+method handles topological changes of evolving interfaces automatically,
+cf.~\citet{Sethian03}, and that it is relatively straightforward to implement.
+
+It should be noted that the automatic handling of topological changes is not
+based on physical principles.  For instance, when two interfaces approach each
+other and their distance becomes less than the spacing of the grid, the
+level-set method can no longer resolve both interfaces and so they are merged.
+An important consequence is that the level-set method does not model the
+physics involved in the coalescence process, and in particular in the smaller
+scales of the film-drainage process.  This process involves a wide range of
+length scales, varying from the nanometer scale where van der Waals force are
+active to the length scales of the external flow.  Some effort has been made to
+include the effects of the smaller scales in front-capturing methods,
+cf.~\cite{Nobari96,Tryggvason10}.  Recently, \citet{Kwakkel13} presented
+a level-set/volume-of-fluid method that is coupled with a film-drainage model
+that predicts if and when two colliding droplets will coalesce.  To prevent the
+numerical coalescence, each droplet has its own locally defined level-set
+function.
+
+The level-set method has been used to model several diverse phenomena,
+such as tumour growth~\cite{Macklin06,Macklin05,Macklin08}, propagation of
+wildland fire~\cite{Mallet09}, and computer RAM production~\cite{Melicher08}.
+For a good and thorough introduction to the level-set method, see
+\cite{Osher03}.
+
+A weakness of the level-set method is that it does not conserve the mass of the
+two fluids, in particular in areas of low resolution and/or high curvature.
+Different approaches have been developed to overcome this disadvantage, for
+example the conservative level-set method~\cite{Olsson05,Olsson07}, the
+particle level-set method~\cite{Enright02}, or the coupled
+level-set/volume-of-fluid method~\cite{Sussman00}.
+
+When we use the level-set method to capture the interface for immiscible and
+incompressible two-phase flow simulations, there will be a sharp change in the
+density and viscosity across the interface.  In this thesis we use the
+ghost-fluid method~\cite{Fedkiw99}, which is a sharp-interface method where the
+jumps are included in the spatial discretizations in a sharp manner.  An
+alternative method is the continuous surface-force method introduced by
+\citet{Brackbill92}, where the density and the viscosity are smeared out across
+the interface through a smoothed Heaviside function.

+\section{Goal and contribution of the present thesis}
+The main goal of the PhD project has been to develop fundamental knowledge of
+two-phase flow phenomenon that are relevant for compact heat exchangers.
+
+In order to do detailed theoretical studies of phenomena that are relevant for
+compact heat exchangers, we need to consider two-phase flows with mass and heat
+transfer in confined and complex geometries.  One such relevant phenomenon is
+the drop-film collision process \cite{Zhao09}.  Even when restricted to
+isothermal and immiscible flows, this simple phenomenon remains a challenge.
+When the level-set method is used to capture the interface, one must be
+particularly careful about how one calculates the interface curvature and
+normal vector.  For instance, when two drops are in near collision there is
+a kink region in the level-set function between the drops, where the gradient
+is discontinuous, see \cref{fig:curvature-problem}.  This discontinuity may
+lead to large errors in the curvature and the normal vector if it is not taken
+into account in the discretization stencils.

+
+As a step towards computing two-phase flow simulations in confined geometries,
+the thesis has considered the diffuse-domain method~\cite{Li09}.  This is
+a method where partial-differential equations in complex domains are extended
+into larger, regular domains with the use of diffuse approximations of the
+physical boundaries.  The approximations converge asymptotically to the
+original problem when the width of the diffuse boundary is reduced.  With this
+method one can use standard numerical methods to solve equations that
+incorporate complex boundaries.
+
+The main contributions of the present thesis are two new methods to calculate
+the curvature and normal vector in a robust manner with the level-set method.
+These methods are shown to yield more accurate calculations of drop-film and
+drop-drop collisions.  The methods are compared with standard methods and with
+other methods from the literature.
+
+In addition, the thesis presents an extension of a diffuse-domain method by
+a high-order correction term for the solution of elliptic problems in complex
+geometries.  New analysis provided in the thesis improves the understanding of
+the diffuse-domain method, and the derived method is shown to be more accurate
+than the existing diffuse-domain method.
+
+\section{Outline of the thesis}
+The thesis is organised as follows: \Cref{chap:two-phase-flow} gives a brief
+overview of the derivation of the governing equations for two-phase flow.  It
+includes a consideration of the fluid-fluid interface conditions and the
+derivation of a simplified jump tensor for the viscous term at the interface.
+
+\Cref{chap:numerical-methods} gives a detailed description of the numerical
+methods that are used to solve the two-phase flow equations.  In particular, it
+describes the level-set method, which is used to capture the interfaces,
+projection methods that are used to solve the Navier-Stokes equations, and the
+spatial and temporal discretization schemes.  At the end of the chapter, an
+overview of the novel discretization methods for the curvature and the normal
+vector is given.
+
+\Cref{chap:diffuse-domain} gives a short introduction to the diffuse-domain
+method for an elliptic problem with Neumann boundary conditions.  It introduces
+the high-order correction term, and shows that the new method converges
+asymptotically with second-order to the original problem.  The chapter presents
+new analysis that shows that the correction term is not necessary for
+second-order convergence.
+
+In \cref{chap:contributions} the main results of the contributed papers A--E
+are summarized, and the author's contributions are highlighted.  Finally,
+\cref{chap:conclusions} gives concluding remarks and provides an outlook for
+future work.
+
+Full-text versions of the research papers A--E are provided in the Appendices

+\chapter{Governing equations for two-phase flow}
+\label{chap:two-phase-flow}
+In this chapter we will give a brief overview of the derivation of the
+governing equations for two-phase flow.  We begin with a consideration of the
+Navier-Stokes equations for single-phase flow.  We then introduce a singular
+surface-force term and derive the Navier-Stokes equations for two-phase flow.
+Finally, we use the Navier-Stokes equations for two-phase flow to derive jump
+conditions at the interface between the phases.
+
+\section{The Navier-Stokes equations for single-phase flow}
+The following is a brief derivation of the Navier-Stokes equations for
+single-phase flows.  For a more thorough derivation of these equations, see for
+instance \citet[§4 and §5]{Aris89} or \citet[Chapter~4]{White03}.
+
+We consider a single-phase, viscous flow in some domain $\Omega$ with boundary
+$\partial\Omega$.  When temperature effects are neglected the flow is described
+by the Cauchy equation
+\begin{equation}
+  \label{eq:cauchy_equation}
+  \rho\left(\cd{\vct u}\right) = \div\tenstr+\rho\vct f,
+\end{equation}
+and the mass conservation equation,
+\begin{equation}
+  \label{eq:cons_of_mass}
+  \pdt\rho + \div(\rho\vct u) = 0.
+\end{equation}
+Here $\rho$ is the fluid density, $\vct u$ is the flow velocity, $t$ is time,
+$\tenstr$ is the stress tensor, $\vct f$ denotes body forces, and $\del$ is
+used to denote the gradient and divergence operators.  The stress tensor for
+Newtonian fluids with zero bulk viscosity is
+\begin{equation}
+  \tenstr = -p\tenI + 2\mu\tenD - \frac 2 3\mu (\trace\tenD) \tenI,
+  \label{eq:viscous_stress_tensor}
+\end{equation}
+where $p$ is the pressure, $\tenI$ is the identity tensor, $\mu$ is the dynamic
+viscosity, and $\trace\tenD$ denotes the trace of the strain-rate tensor
+$\tenD$,
+\begin{equation}
+  \tenD = \frac{1}{2}\left( \grad\vct u + (\grad\vct u)^T \right).
+  \label{eq:deformation_tensor}
+\end{equation}
+For incompressible flow, the mass-conservation equation reduces to
+\begin{equation}
+  \label{eq:navier-stokes-1}
+  \div\vct u = 0,
+\end{equation}
+that is, the velocity field must be divergence free.  If we further assume that
+the viscosity is constant, then it follows that the divergence of the stress
+tensor reduces to
+\begin{equation}
+  \label{eq:stress_tensor}
+  \div\tenstr = -\grad p + \mu\lapl\vct u,
+\end{equation}
+and so the Cauchy equation \eqref{eq:cauchy_equation} becomes
+\begin{equation}
+  \rho\left(\cd{\vct u}\right) = -\grad p + \mu\lapl\vct u + \rho\vct f.
+  \label{eq:navier-stokes-2}
+\end{equation}
+Equations \eqref{eq:navier-stokes-1} and \eqref{eq:navier-stokes-2} are the
+incompressible Navier-Stokes equations for single-phase flow with constant
+viscosity.
+
+\section{The Navier-Stokes equations for two-phase flow}
+We now consider an immiscible two-phase flow of two Newtonian fluids, each with
+its own viscosity and density.  We let $\Omega_1$ and $\Omega_2$ denote the
+domains occupied by fluid 1 and fluid 2, respectively, and let the interface
+between the fluids be denoted by $\Gamma$.  Then $\Omega
+= \Omega_1\cup\Omega_2$ and $\partial\Omega
+= (\partial\Omega_1\cup\partial\Omega_2)\setminus\Gamma$ are the fluid domain
+and its boundary, respectively.  See \cref{fig:domain} for an illustration of
+a two-phase flow domain.

+  \caption{An illustration of a two-phase flow domain.  The interface $\Gamma$
+    separates the two phases $\Omega_1$ and $\Omega_2$.}
+  \label{fig:domain}
+\end{figure}
+
+The extension of the single-phase model to account for two fluids can be made
+by adding a singular surface-force term to represent the effects of surface
+tension between the fluids.  We assume that the surface tension is constant, in
+which case the singular surface force can be defined as
+\begin{equation}
+  \funssf(\vct x,t)
+  = \int_{\Gamma}\sigma\kappa\vct n\delta(\vct x - \vct x_I(\vct s))\dif\vct s,
+  \label{eq:ssf}
+\end{equation}
+where $\sigma$ is the surface tension, $\kappa$ is the local curvature, $\vct
+n$ is the normal vector, $\delta$ is the Dirac delta function, and $\vct
+x_I(\vct s)$ is a parametrisation of the interface.  Thus the Navier-Stokes
+equations for immiscible and incompressible two-phase flow are
+\begin{align}
+  \label{eq:ns1}
+  \div\vct u &= 0, \\
+  \label{eq:ns2}
+  \rho\left(\cd{\vct u}\right) &= -\grad p + \mu\lapl\vct u
+    + \rho\vct f + \funssf.
+\end{align}
+
+\section{Fluid-fluid interface conditions}
+The surface-tension force and the jump in viscosity and density across the
+interface $\Gamma$ lead to a set of interface conditions that must be satisfied
+along the interface $\Gamma$.  The following is a brief derivation of these
+conditions.
+
+First, we only consider flows where there is no mass transfer, which implies
+that
+\begin{equation}
+  \jmp{\vct u}\cdot\vct n = 0,
+\end{equation}
+where $\jmp{\cdot}$ denotes the jump at the interface, for instance $\jmp{\mu}
+= \mu_2 - \mu_1$.  Further, for viscous flows there is no slip at the
+interface, and thus the tangential velocity component of the two fluids must be
+equal at the interface,
+\begin{equation}
+  \jmp{\vct u}\cdot\vct t = 0.
+\end{equation}
+It follows that
+\begin{align}
+  \label{eq:jmpu}
+  \jmp{\vct u} &= 0, \\
+  \label{eq:jmpJut}
+  \jmp{\grad \vct u}\cdot\vct t &= 0.
+\end{align}
+The latter is a direct consequence of the former.  Both fluids are
+incompressible, which gives the trivial identity $\jmp{\div\vct u} = 0$.  If we
+use the identity
+\begin{equation}
+  \div\vct u
+    = \vct n\cdot\grad\vct u\cdot\vct n + \vct t\cdot\grad\vct u\cdot\vct t
+  \label{eq:divuident}
+\end{equation}
+together with \eqref{eq:jmpJut} we get
+\begin{equation}
+  \vct n\cdot\jmp{\grad\vct u}\cdot\vct n = 0,
+  \label{eq:jmpngradun}
+\end{equation}
+which means that the normal component of the normal derivative of the velocity
+field is continuous across the interface.  Note that in \eqref{eq:divuident}
+and in similar expressions in the following, the nabla operator is only applied
+to $\vct u$, not the normal and tangential vectors that follow.

+  \caption{A sketch of the control volume $\Omega_\epsilon$ that covers the
+    interface, $\Gamma$.}
+  \label{fig:domain_omega_epsilon}
+\end{figure}%
+Next, we consider the conservation of momentum.  We define a control volume
+\begin{equation}
+  \Omega_{\epsilon} = \set{\vct x \in \Omega}{\min_{\vct x_I \in \Gamma}|\vct
+    x - \vct x_I| \leq \epsilon},
+\end{equation}
+where $\epsilon > 0$, see \cref{fig:domain_omega_epsilon}.  We then integrate
+the Cauchy equation \eqref{eq:cauchy_equation} with the added singular
+surface-force term over the domain~$\Omega_\epsilon$,
+\begin{multline}
+  \intoepdx{\rho\td{\vct u}}
+    = \intoepdx{\div\tenstr} + \intoepdx{\rho\vct f} \\
+      + \intoepdx{ \int_{\Gamma}\sigma\kappa\vct n\delta(\vct x - \vct
+        x_I(\vct s))\dif\vct s}.
+\end{multline}
+Here $\tdi{\vct u} = \partial\vct u/\partial t + \vct u\cdot\grad\vct u$
+denotes the convective derivative.  Now we apply the Gauss theorem and change
+the order of integration in the last term to obtain
+\begin{equation}
+  \intoepdx{\rho\td{\vct u}} = \intdoepds{\tenstr\cdot\vct n}
+    + \intoepdx{\rho\vct f} + \int_\Gamma\sigma\kappa\vct n\dif\vct s.
+\end{equation}
+If we let $\epsilon$ go to zero, the left-hand side and the second term on the
+right-hand side vanish, and we get
+\begin{equation}
+  0 = \int_\Gamma\left( \jmp{\tenstr}\cdot\vct n + \sigma\kappa\vct
+    n \right)\dif s.
+  \label{eq:stressjumpint}
+\end{equation}
+Since the derivation above is also valid for any subset of $\Omega_\epsilon$
+containing a part of $\Gamma$, \eqref{eq:stressjumpint} must hold for any part
+of $\Gamma$.  Therefore
+\begin{equation}
+  0 = \jmp{\vct T}\cdot\vct n + \sigma\kappa\vct n.
+\end{equation}
+With $\vct T = -p\vct I + 2\mu\vct D$ we finally get the interface condition
+for the stresses,
+\begin{equation}
+  \label{eq:stress_jump}
+  \jmp{p}\vct n - \jmp{2\mu\tenD}\cdot\vct n = \sigma\kappa\vct n.
+\end{equation}
+The surface tension force is seen to introduce a discontinuity in the normal
+stresses across the interface.  The tangential stresses are continuous.
+
+\section{Interface conditions for the pressure and the viscous term}
+The previous section gave a brief derivation of the interface conditions for
+immiscible and incompressible two-phase flow without mass transfer.  In order
+to use these conditions for the discretization of the Navier-Stokes equations
+\eqref{eq:ns1} and \eqref{eq:ns2}, we need to rewrite them into a more suitable
+form.  In particular, we want to find explicit expressions for the jump in the
+pressure $\jmp p$ and the viscous term $\jmp{\mu\grad\vct u}$.  The following
+derivation is based on \cite{Hansen05} and \cite{Kang00}.
+
+First, a jump condition for the pressure is obtained by taking the inner
+product of \eqref{eq:stress_jump} with the normal vector $\vct n$,
+\begin{equation}
+  \jmp p = \vct n\cdot\jmp{2\mu\tenD}\cdot\vct n + \sigma\kappa
+      = 2\jmp{\mu}\vct n\cdot \grad\vct u \cdot\vct n
+        + \sigma\kappa,
+  \label{eq:jump_pressure}
+\end{equation}
+where \eqref{eq:jmpngradun} was used for the second equality.
+
+To find the jump in the viscous term, it is first decomposed into an interface
+normal coordinate system as
+\begin{equation}
+  \begin{split}
+    \jmp{\mu\grad\vct u} &=
+  \left(\vct n\cdot\jmp{\mu\grad\vct u}\cdot\vct n\right)\vct n\otimes\vct n +
+  \left(\vct t\cdot\jmp{\mu\grad\vct u}\cdot\vct t\right)\vct t\otimes\vct t
+        \\ &\quad+
+  \left(\vct n\cdot\jmp{\mu\grad\vct u}\cdot\vct t\right)\vct n\otimes\vct t +
+  \left(\vct t\cdot\jmp{\mu\grad\vct u}\cdot\vct n\right)\vct t\otimes\vct n,
+  \end{split}
+\end{equation}
+where $\otimes$ denotes the dyadic product.  We already showed that
+$\jmp{\grad\vct u}\cdot\vct t = 0$ and $\vct n\cdot\jmp{\grad\vct u}\cdot\vct
+n = 0$, cf.\ \eqref{eq:jmpJut} and \eqref{eq:jmpngradun}, which gives
+\begin{align}
+  \vct n\cdot\jmp{\mu\grad\vct u}\cdot\vct n &=
+    \jmp{\mu}\,\vct n\cdot\grad\vct u\cdot\vct n, \\
+  \vct t\cdot\jmp{\mu\grad\vct u}\cdot\vct t &=
+    \jmp{\mu}\,\vct t\cdot\grad\vct u\cdot\vct t, \\
+  \vct n\cdot\jmp{\mu\grad\vct u}\cdot\vct t &=
+    \jmp{\mu}\,\vct n\cdot\grad\vct u\cdot\vct t.
+\end{align}
+We then take the inner product of \eqref{eq:stress_jump} with $\vct t$, which
+gives
+\begin{equation}
+  \vct t\cdot\jmp{\mu\left(\grad\vct u + (\grad\vct u)^T \right)}\cdot\vct n
+  = \vct t\cdot\jmp{\mu\grad\vct u} \cdot\vct n
+    + \jmp{\mu}\vct n\cdot\grad\vct u \cdot\vct t
+  = 0,
+\end{equation}
+or
+\begin{equation}
+  \vct t\cdot\jmp{\mu\grad\vct u}\cdot\vct n =
+    - \jmp{\mu}\vct n\cdot\grad\vct u \cdot\vct t.
+\end{equation}
+The jump in the viscous term becomes
+\begin{multline}
+  \jmp{\mu\grad\vct u} = \jmp{\mu} \Big(
+       (\vct n\cdot\grad\vct u\cdot\vct n)\vct n\otimes\vct n
+     + (\vct n\cdot\grad\vct u\cdot\vct t)\vct n\otimes\vct t \\
+     - (\vct n\cdot\grad\vct u\cdot\vct t)\vct t\otimes\vct n
+     + (\vct t\cdot\grad\vct u\cdot\vct t)\vct t\otimes\vct t \Big).
+\end{multline}
+This can be simplified further by noting that
+\begin{equation}
+  (\grad\vct u\cdot t)\otimes\vct t
+  = (\vct n\cdot\grad\vct u\cdot\vct t)\vct n\otimes\vct t
+    + (\vct t\cdot\grad\vct u\cdot\vct t)\vct t\otimes\vct t.
+\end{equation}
+Thus we obtain the expression for the jump in the viscous term that has been

+This chapter has given a brief derivation of the immiscible and incompressible
+Navier-Stokes equations for two-phase flow \eqref{eq:ns1} and \eqref{eq:ns2},
+where the viscosity is assumed constant in each phase.  The effect of surface
+tension is included as a singular source term.
+
+Fluid-fluid interface conditions have been discussed, and it has been shown how
+the singular source term and a jump in viscosity lead to a set of interface
+jump conditions for the pressure \eqref{eq:jump_pressure} and the viscous term
+\eqref{eq:jumptens}.

+\chapter{Numerical methods}
+\label{chap:numerical-methods}
+This chapter describes the numerical methods that have been used in this thesis
+to solve the Navier-Stokes equations for two-phase flow.  First, a brief
+introduction to the level-set method is given, which is followed by an outline
+of the two projection methods that have been used to solve the Navier-Stokes
+equations.  The spatial and temporal discretization methods are then
+summarized, and at the end of the chapter the new methods to calculate the
+curvature and the normal vectors are presented.
+
+\section{The level-set method}
+\label{sec:level-set}
+In order to solve the Navier-Stokes equations for two-phase flow, we need to
+know the location of the interface.  The level-set method proposed by
+\citet{Osher88} allows us to capture the interface location as the zero level
+set of the level-set function $\varphi(\vct x,t)$.  The level-set function is
+typically defined as a signed-distance function,
+\begin{equation}
+  \varphi(\vct x,t) = \begin{cases}
+     d(\vct x,t) & \text{if } \vct x\in\Omega_2, \\
+    -d(\vct x,t) & \text{if } \vct x\in\Omega_1, \\
+  \end{cases}
+\end{equation}
+where $d(\vct x,t)$ is the shortest distance to the interface $\Gamma$,
+\begin{equation}
+  d(\vct x,t) = \min_{\vct x_I \in \Gamma} |\vct x - \vct x_I|.
+\end{equation}
+Thus the interface can be defined implicitly as
+\begin{equation}
+  \Gamma(t) = \set{\vct x\in\Omega}{\varphi(\vct x,t)=0},
+              \quad t\in \mathbb R^+.
+\end{equation}
+
+The position of the interface is updated by solving an advection equation for
+$\varphi$,
+\begin{equation}
+  \label{eq:ls_adeq}
+  \pdt{\varphi} + \vct{\hat u}\cdot\grad\varphi = 0,
+\end{equation}
+where $\vct{\hat u}$ is the velocity at the interface extended to the entire
+domain.  We extend the interface velocity through solving
+a velocity-extrapolation equation,
+\begin{equation}
+  \label{eq:ls_velextr}
+  \pd{\vct{\hat u}}{\tau} + S(\varphi)\vct n\cdot\grad\vct{\hat u} = 0,
+  \quad \vct{\hat u}_{\tau=0} = \vct u,
+\end{equation}
+to steady state, cf.\ \cite{Adalsteinsson99,Zhao96}.  Here $\tau$ is
+a pseudo-time and $S$ is a smeared sign function which is equal to zero at the
+interface,
+\begin{equation}
+  S(\varphi) = \frac{\varphi}{\sqrt{\varphi^2+2\Delta x^2}}.
+\end{equation}
+
+When we solve the level-set equation \eqref{eq:ls_adeq}, the non-uniform
+advection will distort the signed-distance property of the level-set function,
+and numerical dissipation error adds to this distortion.  The level-set
+function is therefore reinitialized regularly by solving
+\begin{equation}
+  \label{eq:ls_reinit}
+  \begin{split}
+    \pd{\varphi}{\tau} + S(\varphi_0)(|\grad\varphi|-1) &= 0, \\
+    \varphi(\vct x,0) &= \varphi_0(\vct x),
+  \end{split}
+\end{equation}
+to steady state as proposed by \citet{Sussman94}.  The level-set function just
+before initialization is used as the initial condition $\varphi_0$.
+
+The level-set equations \eqref{eq:ls_adeq}, \eqref{eq:ls_velextr}, and
+\eqref{eq:ls_reinit} are discretized in time and space as described in the
+following sections.  The method presented by \citet{Adalsteinsson95} is used to
+improve the computational speed.  The method is often called the narrow-band
+method, since the level-set function is only updated in a narrow band across
+the interface at each time step.
+
+One of the advantages of the level-set method is that normal vectors and
+curvatures can be readily calculated from the level-set function, that is,
+\begin{align}
+  \label{eq:norm}
+  \vct n &= \frac{\grad\varphi}{|\grad\varphi|}, \\
+  \label{eq:curv}
+  \kappa &= \div\left(\frac{\grad\varphi}{|\grad\varphi|}\right).
+\end{align}
+
+\section{Projection methods}
+\label{sec:projection-method}
+We have employed two different projection methods in this thesis to solve the
+incompressible Navier-Stokes equations for two-phase flow \eqref{eq:ns1} and
+\eqref{eq:ns2}.  Papers A, B, and C used the direct projection
+scheme~1~(DP1)~\cite{Hansen05}, and Paper D used the more standard Chorin
+projection method \cite{Chorin68}.
+
+The projection methods are a family of methods for the solution of the
+incompressible Navier-Stokes equations that are based on the Helmholtz-Hodge
+theorem.  This theorem states that an arbitrary vector field can be decomposed
+into a divergence-free part and a rotation-free part.  That is, any vector
+field $\vct a$ can be written as
+\begin{equation}
+  \vct a = \vct a' + \grad\psi,
+\end{equation}
+where $\vct a'$ is a vector with $\div\vct a' = 0$ and $\psi$ is a scalar
+potential.  The proof of this theorem can be found in for instance
+\cite[§3.44]{Aris89} or \cite{Chorin00}.
+
+\subsection{The direct projection scheme 1}
+The DP1 was developed by \citet{Hansen05} and is based on a direct application
+of the Helmholtz-Hodge theorem.  We assume that the velocity $\vct u$ is
+sufficiently smooth, and then rewrite \eqref{eq:navier-stokes-2} to get
+\begin{equation}
+  \label{eq:divFreeVel}
+  \pdt{\vct u} = \vct w - \frac{\grad p}{\rho},
+\end{equation}
+where
+\begin{equation}
+  \vct w = - (\vct u\cdot\grad)\vct u + \nu\grad^2\vct u + \vct f.
+  \label{eq:continuousRightHandVector}
+\end{equation}
+The divergence of \eqref{eq:divFreeVel} yields a Poisson equation for the
+pressure,
+\begin{equation}
+  \div\left(\frac{\grad p}{\rho}\right) = \div\vct w.
+  \label{eq:PoissonDP1}
+\end{equation}
+The DP1 scheme follows from a direct numerical discretization of the above
+equations.  First, $\vct w$ is calculated with
+\eqref{eq:continuousRightHandVector}.  Then the pressure is found by solving
+the Poisson equation \eqref{eq:PoissonDP1}.  Finally, an Euler step is used to
+solve \eqref{eq:divFreeVel}, that is,
+\begin{equation}
+  \vct u^{n+1} = \vct u^n + \Delta t\left(\vct w - \frac{\grad p}{\rho}\right).
+  \label{eq:dp1-update}
+\end{equation}
+
+\subsection{The Chorin projection method}
+The Chorin projection method was presented by \citet{Chorin68}, and is today
+one of the standard methods for solving the Navier-Stokes equations, e.g.\
+\cite{Walker12}.  The method is briefly presented in the following.
+
+Let $\Delta t$ be the time step, and consider the discretization of the
+momentum equation \eqref{eq:navier-stokes-2} with the forward Euler method,
+\begin{equation}
+  \frac{\vct u^{n+1} - \vct u^n}{\Delta t}
+  = -\vct u^n\cdot\grad\vct u^n
+    - \frac{\grad p^{n+1}}{\rho} + \frac\mu\rho\lapl\vct u^n + \vct f,
+  \label{eq:discmomeq}
+\end{equation}
+where $\vct u^n\equiv\vct u(\vct x,n\Delta t)$ and $p^n\equiv p(\vct x,n\Delta
+t)$ are assumed known at time level $n$.  Note that the pressure gradient is
+evaluated at time level $n+1$.  Next, to solve \eqref{eq:discmomeq} in two
+steps, we introduce the intermediate velocity field $\vct u^\star$,
+\begin{equation}
+  \frac{\vct u^{n+1} - \vct u^\star + \vct u^\star - \vct u^n}{\Delta t}
+  = -\vct u^n\cdot\grad\vct u^n
+    - \frac{\grad p^{n+1}}{\rho} + \frac\mu\rho\lapl\vct u^n + \vct f,
+\end{equation}
+which is chosen such that
+\begin{align}
+  \label{eq:ustar}
+  \frac{\vct u^\star - \vct u^n}{\Delta t}
+    &= -\vct u^n\cdot\grad\vct u^n + \frac\mu\rho\lapl\vct u^n + \vct f, \\
+  \label{eq:unext}
+  \frac{\vct u^{n+1} - \vct u^\star}{\Delta t} &= - \frac{\grad p^{n+1}}{\rho}.
+\end{align}
+From \eqref{eq:ustar} we get an explicit expression for $\vct u^\star$,
+\begin{equation}
+  \vct u^{\star} = \vct u^n
+    + \Delta t\left(-\vct u^n\cdot\grad\vct u^n
+        + \frac\mu\rho\,\lapl\vct u^n + \vct f\right).
+\end{equation}
+Next, the divergence of \eqref{eq:unext} and $\div\vct u^{n+1} = 0$ yields
+a Poisson equation for the pressure,
+\begin{equation}
+  \div\left(\frac{\grad p^{n+1}}{\rho}\right)
+    = \frac{\div\vct u^\star}{\Delta t}.
+  \label{eq:PoissonChorin}
+\end{equation}
+Finally, we obtain for \eqref{eq:unext}
+\begin{equation}
+  \vct u^{n+1} = \vct u^\star - \Delta t\frac{\grad p^{n+1}}{\rho}.
+  \label{eq:velcorrection}
+\end{equation}
+
+\section{Spatial discretization}
+\label{sec:x-discr}
+The governing equations \eqref{eq:ns1}, \eqref{eq:ns2}, \eqref{eq:ls_adeq},
+\eqref{eq:ls_velextr}, and \eqref{eq:ls_reinit} are discretized on a staggered
+grid~\cite{Harlow65}, where the scalar values are located at the cell centres
+and the vector values are located at the cell edges, see
+\cref{fig:staggered-grid}.  The domain boundary coincides with cell edges, and
+the fixed grid spacing is $\Delta x$ in the $x$ direction and $\Delta y$ in the
+$y$ direction.

+\end{figure}
+
+The $x$- and $y$-derivatives, divergence, and Laplacian operators are

+    &= \frac{p_{i+1,j} - p_{i,j}}{\Delta x}, \\

+       + \frac{p_{i,j+1} - 2p_{i,j} + p_{i,j-1}}{(\Delta y)^2},
+\end{align}
+respectively.  Here $\vct u = (u,v)$ is a vector and $p$ is a scalar.  Note
+that the gradient of a scalar is a vector and has values located at the cell
+edges.  These definitions are consistent with the staggered grid, since the
+gradient returns a vector with components defined on the cell faces, while the
+divergence and the Laplacian returns a scalar defined at the cell centres.
+
+\subsection{Advective terms}
+The advective terms, $\vct u\cdot\grad\vct u$ in the momentum equation
+\eqref{eq:ns2} and $\vct{\hat u}\cdot\grad\varphi$ in the level-set equation
+\eqref{eq:ls_adeq}, and the normal derivative $\vct n\cdot\grad\vct{\hat u}$ in
+the velocity-extrapolation equation \eqref{eq:ls_velextr} are discretized with
+the weighted essentially non-oscillatory (WENO) scheme, cf.~\cite{Fedkiw99}
+and~\cite{Jiang96}.  The WENO scheme is a high-order upwind scheme that is
+fifth-order accurate in smooth regions.  In nonsmooth regions the accuracy is
+reduced to a minimum of third order.  The following is a brief outline of the
+WENO scheme.
+
+First, when we calculate the advective term for the velocity, the vector
+components are required on all cell edges.  That is, we must interpolate the
+$x$-component of the velocity to the location of the $y$-component of the
+velocity and vice versa.  To do this we use a linear interpolation,
+\begin{align}
+  u_{i,j+\frac 1 2} &= \frac 1 4\left(
+      u_{i-\frac 1 2,j  } + u_{i-\frac 1 2,j+1}
+    + u_{i+\frac 1 2,j+1} + u_{i+\frac 1 2,j  } \right), \\
+  v_{i+\frac 1 2,j} &= \frac 1 4\left(
+      v_{i,  j-\frac 1 2} + v_{i+1,j-\frac 1 2}
+    + v_{i+1,j+\frac 1 2} + v_{i  ,j+\frac 1 2} \right).
+\end{align}
+
+Similarly, when we calculate the advective term for the level-set function
+$\varphi$, we first interpolate the velocity to the scalar grid,
+\begin{align}
+  u_{i,j} &= \frac 1 2\left( u_{i+\frac 1 2,j} + u_{i-\frac 1 2,j} \right), \\
+  v_{i,j} &= \frac 1 2\left( v_{i,j+\frac 1 2} + v_{i,j-\frac 1 2} \right).
+\end{align}
+
+We now consider the WENO scheme for the advective operator in 1D at the point
+$x_{i+\frac 1 2}$.  The scheme extends naturally to higher dimensions.  First,
+if $u_{i+\frac 1 2} = 0$, then
+\begin{equation}
+  \left. u\pd u x \right|_{i+\frac 1 2} = 0.
+\end{equation}
+Otherwise we need to calculate a set of five differences that depend on the
+upwind direction.  The differences are denoted $\Delta v_k$ for $k=1,\dots,5$.
+If $u_{i+\frac 1 2}>0$, then we calculate
+\begin{equation}
+  \Delta v_k = \frac{u_{i+\frac{2k-5} 2} - u_{i+\frac{2k-7} 2}}{\Delta x}.
+\end{equation}
+Otherwise if $u_{i+\frac 1 2}<0$, we calculate
+\begin{equation}
+  \Delta v_k = \frac{u_{i-\frac{2k-9} 2} - u_{i-\frac{2k-7} 2}}{\Delta x}.
+\end{equation}
+Next we calculate expressions for the smoothness of three substencils,
+\begin{align}
+  S_1 &= \frac{13}{12}(\Delta v_1 - 2\Delta v_2 + \Delta v_3)^2
+    + \frac 1 4 (\Delta v_1 - 4\Delta v_2 + 3\Delta v_3)^2, \\
+  S_2 &= \frac{13}{12}(\Delta v_2 - 2\Delta v_3 + \Delta v_4)^2
+    + \frac 1 4 (\Delta v_2 - \Delta v_4)^2, \\
+  S_3 &= \frac{13}{12}(\Delta v_3 - 2\Delta v_4 + \Delta v_5)^2
+    + \frac 1 4 (3\Delta v_3 - 4\Delta v_4 + \Delta v_5)^2,
+\end{align}
+where a small $S$ indicates a smooth substencil.  These smoothness factors are
+then used to compute weights for the substencils,
+\begin{equation}
+  w_k = \frac{b_k}{b_1+b_2+b_3},
+\end{equation}
+for $k = 1,2,3$, where
+\begin{equation}
+  b_1 = \frac 1 {10}\frac 1 {(\epsilon+S_1)^2},\quad
+  b_2 = \frac 6 {10}\frac 1 {(\epsilon+S_2)^2},\quad
+  b_3 = \frac 3 {10}\frac 1 {(\epsilon+S_3)^2}.
+\end{equation}
+Here $\epsilon$ is a regularization parameter that is used to avoid division by
+zero.  We have used $\epsilon = 10^{-6}$ in this work.  Finally, the WENO
+scheme for the gradient becomes
+\begin{multline}
+  \left. \pd u x \right|_{i+\frac 1 2} \simeq
+      w_1\left(\frac 1 3\Delta v_1 - \frac 7 6\Delta v_2
+        + \frac{11} 6 \Delta v_3\right) \\
+    + w_2\left(-\frac 1 6\Delta v_2 + \frac 5 6\Delta v_3
+        + \frac 1 3 \Delta v_4\right) \\
+    + w_3\left(\frac1 3\Delta v_3 + \frac 5 6\Delta v_4
+        - \frac 1 6 \Delta v_5\right).
+\end{multline}
+
+\subsection{The viscous term}
+The viscous term $\mu\lapl\vct u$ in the Navier-Stokes equations is discretized
+by standard second-order central differences using the ghost-fluid method
+(GFM)~\cite{Fedkiw99,Kang00,Liu00}.  This method includes the jump in the
+viscous term at the interface \eqref{eq:jumptens} in the discretization stencil
+in a sharp manner.
+
+In the following we present the GFM scheme in the one-dimensional case.  The
+extension to higher dimensions is straightforward.  In order to simplify the
+notation, we omit the half indices and let $k\equiv i+\frac 1 2$.  Further, we
+consider a general case where
+\begin{equation}
+  \jmp u = a_\Gamma, \qquad \jmp{\mu\pd u x} = b_\Gamma.
+\end{equation}
+For the viscous term, $a_\Gamma = 0$, cf.\ \eqref{eq:jmpu}, and $b_\Gamma$ is
+given by the jump tensor~\eqref{eq:jumptens}.  The jump tensor is calculated at
+the cell centres near the interface with the second-order central-difference
+scheme.  It is then interpolated linearly to the cell edges, from where it is
+again interpolated linearly to the interface when needed.
+
+If the interface does not cross the stencil, then the GFM scheme reduces to the
+standard second-order central-difference stencil.  Else there are four
+stencils, depending on the location of the interface.  One such interface
+configuration is sketched in \cref{fig:gfm-scheme-example}.  In all the
+stencils, $\theta$ is defined as the relative distance from the interface to
+the node on the left, for instance
+\begin{equation}
+  \theta = \frac{|\varphi_{k}|}{|\varphi_{k}| + |\varphi_{k+1}|},
+\end{equation}
+where $\varphi_k$ and $\varphi_{k+1}$ are the level-set function values
+linearly interpolated to the vector grid.  The four stencils are given below,
+where $h\equiv\Delta x$.
+\begin{enumerate}
+  \item Phase 1 is to the left and interface lies between $k$ and $k+1$:
+    \begin{align}
+      \begin{split}
+        \left.\pd{} x\left(\mu\pd u x\right)\right|_{x_k}
+          &= \frac{\hat\mu\left(u_{k+1} - u_{k}\right)
+                 - \mu_1\left(u_{k} - u_{k-1}\right)}{h^2} \\

+          &= \frac{\mu_2\left(u_{k+1} - u_{k}\right)
+                - \hat\mu\left(u_{k} - u_{k-1}\right)}{h^2} \\

+          &= \frac{\mu_1\left(u_{k+1} - u_{k}\right)
+                - \hat\mu\left(u_{k} - u_{k-1}\right)}{h^2} \\
+          &\qquad

+\subsection{Pressure Poisson equation}
+\label{sec:pressure-poisson}
+The Laplace operator in the Poisson equations \eqref{eq:PoissonDP1} and
+\eqref{eq:PoissonChorin} is also discretized by standard second-order central
+differences using the GFM~\cite{Kang00,Liu00}.  The GFM was discussed in the
+previous section, where stencils were given for the viscous term in the
+one-dimensional case.  For the pressure, the stencils are the same except we
+use $p$ instead of $u$, and $1/\rho$ and $1/\hat\rho$ instead of $\mu$ and
+$\hat\mu$.  To find the jump in the pressure at the interface, $\jmp
+p = a_\Gamma$, the jump condition \eqref{eq:jump_pressure} is calculated at the
+cell centres and then interpolated to the interface.  In addition, we use that
+$b_\Gamma = 0$, which is justified by \citet[Section~3.7]{Kang00}.
+
+The resulting linear system for the pressure is solved with a solver from the
+Portable, Extensible Toolkit for Scientific Computation (PETSc)~\cite{PETSc}.
+PETSc makes available a large selection of solvers.  In most cases, we used the
+direct solver based on LU factorisation or the conjugate gradient method with
+incomplete Cholesky factorisation.  In some cases, we used the GMRES solver
+with a preconditioner, either incomplete LU factorisation or an algebraic
+multigrid method.  See \cite{PETSc} for more details and a list of available
+methods, and see for example~\cite{Iserles09} or~\cite{Saad03} for an
+introduction to linear solvers.
+
+Finally, the gradient of the pressure, used in \eqref{eq:divFreeVel} and
+\eqref{eq:velcorrection}, is also calculated with the GFM.  In one dimension,
+the stencil is
+\begin{align}
+  \left. \frac 1 \rho \pd p x\right|_{i+\frac 1 2}
+           &= \frac 1 {\hat\rho} \frac{(p_{i+1} - a_\Gamma) - p_i} h, \\
+  \hat\rho &= \theta\rho_1 + (1-\theta)\rho_2,
+\end{align}
+if $\phi_i\leq 0$ and $\phi_{i+1}>0$, or else
+\begin{align}
+  \left. \frac 1 \rho \pd p x\right|_{i+\frac 1 2}
+           &= \frac 1 {\hat\rho} \frac{(p_{i+1} + a_\Gamma) - p_i} h, \\
+  \hat\rho &= \theta\rho_2 + (1-\theta)\rho_1,
+\end{align}
+where
+\begin{equation}
+  \theta = \frac{|\varphi_{i}|}{|\varphi_{i}| + |\varphi_{i+1}|}.
+\end{equation}
+
+\section{Temporal discretization}
+\label{sec:t-discr}
+The temporal discretization is done with the explicit strong
+stability-preserving Runge-Kutta (SSP-RK) schemes, see
+\cite{Ketcheson05,Shu88}.  The idea behind the SSP-RK schemes is to preserve
+the stability of a low-order method when it is extended to higher order.  It is
+argued in \cite{Gottlieb01} that if one extends the forward Euler method, which
+is total variation diminishing (TVD) for a suitable discretization of a scalar
+conservation law, to a non-SSP higher-order method, then overshoots may occur
+at discontinuities.
+
+An SSP-RK method can be written as a convex sum of explicit Euler steps with
+time step $\Delta t$,
+\begin{equation}
+  \mathcal E\left(x^n\right) = x^n + \Delta t \mathcal F(x^n,t^n).
+\end{equation}
+where $\mathcal F$ is the residual of the PDE to be solved.  In this thesis we
+have used two methods:  The third-order three-stage SSP-RK method~\cite{Shu88},
+\begin{equation}
+  \begin{split}
+    x^{(1)} &= \mathcal E\left(x^n\right), \\
+    x^{(2)} &= \frac 3 4 x^n + \frac 1 4\mathcal E\left(x^{(1)}\right), \\
+    x^{n+1} &= \frac 1 3 x^n + \frac 2 3\mathcal E\left(x^{(2)}\right),
+  \end{split}
+  \label{eq:ssprk33}
+\end{equation}
+and the third-order four-stage SSP-RK method~\cite{Kraaijevanger91},
+\begin{equation}
+  \begin{split}
+    x^{(1)} &= \frac 1 2 x^n + \frac 1 2\mathcal E\left(x^n\right), \\
+    x^{(2)} &= \frac 1 2 x^{(1)} + \frac 1 2\mathcal E\left(x^{(1)}\right), \\
+    x^{(3)} &= \frac 2 3 x^n + \frac 1 6 x^{(2)}
+               + \frac 1 6\mathcal E\left(x^{(2)}\right), \\
+    x^{n+1} &= \frac 1 2 x^{(3)} + \frac 1 2\mathcal E\left(x^{(3)}\right).
+  \end{split}
+  \label{eq:ssprk34}
+\end{equation}
+
+The semi-discretized velocity-extrapolation equation \eqref{eq:ls_velextr} and
+level-set reinitialization equation \eqref{eq:ls_reinit} can be written as
+systems of ordinary differential equations (ODEs) of the form
+\begin{equation}
+  \od{\vct \psi} \tau = \vct F(\vct\psi,\tau),
+\end{equation}
+where $\vct\psi$ is a vector containing the discrete variables and $\vct F$
+contains the spatially discretized terms.  The explicit Euler step becomes
+\begin{equation}
+  \mathcal E(\vct\psi^n) = \vct\psi^n + \Delta\tau \vct F(\vct\psi^n,\tau^n).
+\end{equation}
+In this thesis, these equations are solved with the third-order four-stage
+SSP-RK method \eqref{eq:ssprk34}.  The four-stage method is used because it is
+more accurate than the three-stage method.  We wanted to make sure that the
+error is mainly dominated by the spatial discretization.
+
+The semi-discretized Navier-Stokes equations \eqref{eq:navier-stokes-1} and
+\eqref{eq:navier-stokes-2} are solved together with the level-set advection
+equation \eqref{eq:ls_adeq} with the third-order three-stage SSP-RK method
+\eqref{eq:ssprk33}.  Here an explicit Euler step $\mathcal E(\vct
+u^n,\varphi^n)$ consists of the following steps:
+\begin{enumerate}
+  \item Calculate the curvature and the normal vectors from $\varphi^n$ with
+    one of the methods described in \cref{sec:curvature}.
+  \item Calculate the intermediate velocity field, either $\vct w$
+    \eqref{eq:continuousRightHandVector} or $\vct u^\star$ \eqref{eq:ustar}.
+  \item Solve the Poisson equation \eqref{eq:PoissonDP1} or
+    \eqref{eq:PoissonChorin} for the pressure as described in
+    \cref{sec:pressure-poisson}.
+  \item Correct the velocity field with either \eqref{eq:dp1-update} or
+    \eqref{eq:velcorrection}.
+  \item Advect the level-set function $\varphi^n$ with \eqref{eq:ls_adeq}.
+\end{enumerate}
+
+\section{Time step restriction}
+\label{sec:deltaT}
+We employ the Courant-Friedrich-Lewy~(CFL) condition to allow adaptive time
+stepping and to enforce stability.  The CFL condition that is used in this
+thesis is
+\begin{equation}
+  \Delta t = \frac{C}{\frac{C_c + C_v} 2
+             + \sqrt{(C_c + C_v)^2 + 4C_g^2 + 4C_s^2}},
+\end{equation}
+where the CFL restriction $C<1$, and $C_c$, $C_v$, $C_s$, and $C_g$ represent
+the contributions from the convective term, the viscous stresses, the surface
+tension, and the gravity, respectively,
+\begin{align}
+  C_c &=  \frac{\max_{i,j}|u_{i,j}|}{\Delta x}
+        + \frac{\max_{i,j}|v_{i,j}|}{\Delta y}, \\
+  C_v &= 2\max\left(\frac{\mu_1}{\rho_1},\frac{\mu_2}{\rho_2}\right)
+         \left(\frac{1}{\Delta x^2} + \frac{1}{\Delta y^2}\right), \\
+  C_s &= \sqrt{\frac{\sigma\max_{i,j}|\kappa_{i,j}|}
+                    {\max(\rho_1,\rho_2)\min(\Delta x^2,\Delta y^2)}}, \\
+  C_g &= \sqrt{\frac{|g_x|}{\Delta x} + \frac{|g_y|}{\Delta y}}.
+\end{align}
+This CFL condition is discussed in more detail by~\citet{Lervag08}, and it is
+based on the condition by \citet{Kang00}.
+
+\section{Axisymmetry}
+For axisymmetric flow, the governing equations \eqref{eq:ns1} and
+\eqref{eq:ns2} become
+\begin{equation}
+  \frac 1 r \pd{} r\left(r u\right) + \pd v z = 0,
+\end{equation}
+\begin{multline}
+  \rho\left(\pdt u + u\pd u r + v\pd u z\right) = -\pd p r \\
+    + \mu\left(\frac 1 r \pd{} r\left(r \pd u r\right)
+          + \pdd u z - \frac u {r^2}\right) + \rho f_r + {f_s}_r,
+\end{multline}
+and
+\begin{multline}
+  \rho\left(\pdt v + u\pd v r + v\pd v z\right) = -\pd p z \\
+    + \mu\left(\frac 1 r \pd{} r\left(r \pd v r\right)
+      + \pdd v z\right) + \rho f_z + {f_s}_z.
+\end{multline}
+Here $u$ and $v$ are the radial and axial velocity components, $f_r$ and $f_z$
+are the radial and axial body-force components, and ${f_s}_r$ and ${f_s}_z$ are
+the radial and axial components of the singular surface force, respectively.
+The equations are solved as explained in the previous sections.
+
+\section{Discretization of the curvature and the normal vector}
+\label{sec:curvature}
+As stated in \cref{sec:level-set}, the normal vector \eqref{eq:norm} and the
+curvature \eqref{eq:curv} can be calculated from the level-set function as
+\begin{align*}
+  \vct n &= \frac{\grad\varphi}{|\grad\varphi|}, \\
+  \kappa &= \div\left(\frac{\grad\varphi}{|\grad\varphi|}\right).
+\end{align*}
+They are typically discretized with the standard second-order
+central-difference scheme, cf.\ \cite{Kang00,Sethian03,Xu06}.  The normal
+vector is calculated at the cell edges, and the curvature is calculated at the
+grid nodes.  The curvature is then interpolated to the interface where needed
+with linear interpolation, for instance with
+\begin{equation}
+  \kappa_\Gamma = \frac{|\varphi_{i,j}|\kappa_{i+1,j}
+  + |\varphi_{i+1,k}|\kappa_{i,j}}{|\varphi_{i,j}| + |\varphi_{i+1,j}|}.
+  \label{eq:curvature-gamma}
+\end{equation}
+
+If the level-set method is used to capture non-trivial geometries, then it will
+contain kink regions, that is, areas where the gradient of the level-set
+function is discontinuous.  \Cref{fig:level-set-function} shows a simple
+example of such a kink region for a level-set function in a one-dimensional
+domain that captures two interfaces, one on each side of $x_i$.  The kink at
+$x_i$ may lead to large errors both for the curvature and the normal vector if
+one is not careful.  Errors in the curvature lead to errors in the surface
+tension force and in the pressure, which in turn lead to errors in the
+interface evolution and in the two-phase flow.  Errors in the normal vector
+affect both the calculation of the viscous jump condition and the advection of
+the interface.  If the level-set method is used to study for example
+coalescence and breakup of drops, these errors may severely affect the
+simulations.

+
+This problem was to our knowledge first described by \citet{Smereka03}, who
+increase the numerical smoothing in the curvature discretization to lessen the
+effect.  Several non-smearing approaches have subsequently been developed.
+\citet{Macklin05} used the level-set method to study tumor growth, and they
+present a one-sided direction-difference scheme for the discretization of the
+normal vector and the curvature.  Later, \citet{Macklin06} presented an
+improved geometry-aware curvature discretization, where the curvature is
+calculated based on a local least-squares parametrisation of the interface.
+
+A different approach to avoid the kinks was presented by \citet{Salac08}.  They
+used a level-set extraction technique, where an extraction algorithm was used
+to reconstruct separate level-set functions for each distinct \emph{body}.  The
+term \emph{body} is used here to denote a subset of a given phase or fluid.
+For example, in the case of two drops of water colliding in air, the water
+drops would make two distinct bodies.  One can also avoid the extraction
+algorithm altogether by use of multiple marker functions for different bodies,
+see for instance \cite{Coyajee09,Kwakkel12}.  Note, however, that the latter
+approach means that the different bodies will not coalesce unless explicit
+action is made, cf.~\cite{Kwakkel13}.  Also, both of the approaches mentioned
+here fails to handle the problem of kinks from a single body.  That is, there
+may still be kink areas due to deformed bodies, for instance bodies with thin
+filaments or tails, or bodies shaped like horse shoes.
+
+In the following, we first present the direction-difference
+scheme~\cite{Macklin05}.  We then describe the curve-fitting discretization
+method and the local level-set extraction method.
+
+\subsection{Direction-difference scheme}
+\label{sec:dds}
+The direction-difference scheme (DDS) was introduced by \citet{Macklin05}.  It
+uses a quality function to ensure that the difference stencils never cross any
+kink regions.  The DDS is used in Papers A--C to calculate the normal vectors.
+However, in Paper C it is shown that the DDS does not always yield an accurate
+approximation of the normal vector.
+
+The basic strategy is to use a combination of central differences and one-sided
+differences based on the values of a quality function,
+\begin{equation}
+  Q(\vct x) = \left| 1 - |\grad\varphi(\vct x)|\right|.
+  \label{eq:quality}
+\end{equation}
+The quality function is approximated with central differences, and is used to
+detect the areas where the level-set function differs from the signed-distance
+function.  In the following, let $Q_{i,j} \equiv Q(\vct x_{i,j})$ and define
+a parameter $\eta>0$.  This threshold parameter is tuned such that the quality
+function will detect all the kinks.
+
+The quality function is used to define a direction function,
+\begin{equation}
+  \vct D(\vct x_{i,j}) = (D_x(\vct x_{i,j}), D_y(\vct x_{i,j})),
+\end{equation}
+where
+\begin{equation}
+  D_x(\vct x_{i,j}) = \begin{cases}
+    -1 & \text{if $Q_{i-1,j}<\eta$ and $Q_{i+1,j}\geq\eta$,} \\
+     1 & \text{if $Q_{i-1,j}\geq\eta$ and $Q_{i+1,j}<\eta$,} \\
+     0 & \text{if $Q_{i-1,j}<\eta$ and $Q_{i,j}<\eta$ and $Q_{i+1,j}<\eta$,} \\
+     0 & \text{if $Q_{i-1,j}\geq\eta$ and $Q_{i,j}\geq\eta$ and
+         $Q_{i+1,j}\geq\eta$,} \\
+     4 & \text{otherwise.}
+  \end{cases}
+  \label{eq:dirfunc}
+\end{equation}
+$D_y(\vct x_{i,j})$ is defined in a similar manner.  If $D_x(\vct x_{i,j})
++ D_y(\vct x_{i,j}) > 2$, then $\vct D(\vct x_{i,j})$ is chosen as the vector
+normal to $\grad\varphi(\vct x_{i,j})$.  It is normalized, and the sign is
+chosen such that it points in the direction of the best quality.  See
+\cite{Macklin05} for more details.
+
+The DDS is then defined as
+\begin{equation}
+  \partial_x f_{i,j} = \begin{cases}
+    \frac{f_{i,j} - f_{i-1,j}}{\Delta x}    & \text{if $D_x(x_i,y_j) = -1$,} \\
+    \frac{f_{i+1,j} - f_{i,j}}{\Delta x}    & \text{if $D_x(x_i,y_j) =  1$,} \\
+    \frac{f_{i+1,j} - f_{i-1,j}}{2\Delta x} & \text{if $D_x(x_i,y_j) =  0$,}
+  \end{cases}
+  \label{eq:Ddifference}
+\end{equation}
+and similarly for $\partial_y f_{i,j}$, where $f_{i,j}$ is a piecewise smooth
+function.  The DDS is equivalent to using central differences in smooth areas
+and one-sided differences in areas close to the kinks.
+
+\subsection{Curve-fitting discretization method}
+\label{sec:curvature-curve-fitting}
+The curve-fitting discretization method (CFDM) was first presented
+in~\cite{Lervag11} and is based on the method by \citet{Macklin06}.  The main
+idea is to identify kink regions with the quality function \eqref{eq:quality},
+and to use a curve parametrisation of the closest interface to calculate the
+curvature in regions where the quality function is larger than the threshold
+parameter, $\eta$.
+
+The CFDM applied to the curvature or the normal vector at the grid point $\vct
+x_{i,j}$ can be summarized as follows.  See also \cref{fig:cfdm}, which shows
+an example of the CFDM used at $\vct x_{i,j}$.
+\begin{enumerate}
+  \item If the quality of the level-set function in the neighbourhood of $\vct
+    x_{i,j}$ is good, that is
+    \[
+      Q(\vct{x}_{n,m}) \le \eta \; \forall (n,m) \in [i-1,i+1]\times[j-1,j+1],
+    \]
+    then we use a standard discretization.  Otherwise continue to the next
+    step.
+  \item Locate the closest interface, $\Gamma$.
+  \item Find a set of points on the located interface, $\vct x_1, \dots, \vct
+    x_n \in \Gamma$.
+  \item Create a parametrisation $\vct \gamma(s)$ of the points $\vct x_1,
+    \dots, \vct x_n$.
+  \item Use the parametrisation $\vct \gamma(s)$ to calculate a local level-set
+    function.
+  \item Use a standard discretization of the local level-set function to
+    calculate the curvature or the normal vector.
+\end{enumerate}

+\subsection{Local level-set extraction method}
+\label{sec:lolex}
+The local level-set extraction (LOLEX) method is based on the method presented
+by \citet{Salac08}, here called the SLM.  It was found that the latter method
+was insufficient, because it did not treat all the kink problems.  The LOLEX
+method is therefore a further development of the SLM, in that it handles the
+kink regions in a more general manner.
+
+The LOLEX method applied to the curvature or the normal vector at a grid point
+$\vct x_{i,j}$ is summarized by the following algorithm.  The algorithm is
+presented with 2D notation for clarity, and extends easily to 3D.  See also
+\cref{fig:lolex}, which gives a simple example of the procedure.
+\begin{enumerate}
+  \item If the quality in the neighbourhood of $\vct x_{i,j}$ is good, that is
+    \[
+      Q(\vct{x}_{n,m}) \le \eta \; \forall (n,m) \in [i-1,i+1]\times[j-1,j+1],
+    \]
+    then we use a standard discretization.  Otherwise continue to the next
+    step.
+  \item Copy a small, local square centred around $\vct x_{i,j}$ from the
+    level-set function $\varphi$ into a local array $\varphi_\text{loc}$.
+  \item Identify and enumerate all the \emph{bodies} in the local array
+    $\varphi_\text{loc}$.  A \emph{body} is here defined as a set of
+    neighbouring points where $\varphi_\text{loc}<0$, see \cref{fig:lolex}.
+    There will be $n\geq 0$ bodies in any given $\varphi_\text{loc}$ array.
+  \item If no body is identified, that is, if $n=0$, then use a standard
+    discretization with the global level-set function $\varphi$.  Otherwise
+    continue to the next step.
+  \item For each body $n$, extract the relevant parts of $\varphi_\text{loc}$
+    into an array $\varphi_\text{loc}^n$.  If necessary, extrapolate values to
+    ghost cells.
+  \item For each body, $n$, reinitialize $\varphi_\text{loc}^n$.
+  \item At this step, all the bodies in the local grid have their own
+    local level-set functions that have been reinitialized to proper
+    signed-distance functions.  Due to the separation of the bodies, there
+    are no longer any kinks.
+  \item Use the standard discretization of the curvature and the normal
+    vector at the local level-set function that represents the body that is
+    closest to $\vct x_{i,j}$.

+\chapter{The diffuse-domain approach}
+\label{chap:diffuse-domain}
+In the previous chapters, we have considered the modelling of two-phase flows,
+and in particular methods for calculating the curvature and normal vector with
+the level-set method in a reliable manner.  In this chapter, we consider
+a different problem of a more general nature:  How to solve partial
+differential equations (PDEs) in complex domains.  In particular, we consider
+an extension of a diffuse-domain method (DDM) by a high-order correction term
+that gives increased accuracy with respect to interface-width refinements.
+
+We begin with a short introduction to the diffuse-domain approach.  We then
+outline how it can be used to derive a DDM for the steady reaction-diffusion
+equation with Neumann boundary conditions.  Next, we continue with a brief
+introduction to the method of matched asymptotic expansions.  Finally, we
+introduce the high-order correction term derived in Paper~E and show that the
+resulting DDM converge with second order in the diffuse-interface width to the
+original problem.  The analysis also shows that the correction term is not
+necessary for second-order convergence.
+
+\section{Introduction}
+There exist several methods for solving PDEs in complex domains.  Most of them
+have in common that they require tools or methods that are not frequently
+available in standard finite-element or finite-difference software packages.
+Examples of such methods include the immersed-interface method
+\cite{LeVeque94}, the matched interface and boundary method \cite{Zhou06}, the
+extended and composite finite-element method \cite{Dolbow09}, embedded boundary
+methods \cite{Johansen98}, cut-cell methods \cite{Ji06}, and ghost-fluid
+methods \cite{Fedkiw99}.  A different approach, known as the fictitious domain
+method~\cite{Glowinski94,Glowinski96} or the domain imbedding
+method~\cite{Buzbee71}, either augments the original system with equations for
+Lagrange multipliers to enforce the boundary conditions, or use the penalty
+method to enforce the boundary conditions weakly.  For a more complete list of
+references, see Paper~E.
+
+The DDM is an alternative method for solving PDEs in complex domains.  The main
+idea is to use an implicit representation of the boundary, where the sharp
+boundary is replaced by a diffuse layer.  The PDEs are then reformulated on
+a larger, regular domain, and the boundary conditions are incorporated via
+source terms in the diffuse layer.  When the thickness of the diffuse layer is
+reduced, these source terms tend towards singular source terms.  The resulting
+PDEs can then be solved with the use of standard tools and methods.
+
+The diffuse-domain approach was first introduced by \citet{Kockelkoren03} to
+study diffusion inside a cell with homogeneous Neumann boundary conditions at
+the cell boundary.  It was later used by \citet{Li09} to develop a DDM for
+solving PDEs in complex evolving domains with Dirichlet, Neumann and Robin
+boundary conditions, which is hereafter called the DDM1.  The DDM1 has been
+used by \citet{Teigen09-b}, who modelled bulk-surface coupling of material
+quantities on a deformable interface.  It was also used by \citet{Aland10} to
+simulate incompressible two-phase flows in complex domains in 2D and 3D, and by
+\citet{Teigen11} to study two-phase flows with soluble surfactants.
+
+An analysis of the error behaviour of the diffuse-domain approach was done by
+\citet{Franz12} for a diffuse-domain approximation of an elliptic problem with
+Dirichlet boundary conditions.  They considered the infinity norm of the
+difference of the approximated solution and the exact solution, and their
+analysis shows that the approximation quality is of order one in the interface
+width.
+
+In Paper~E, we present the DDM2, which is an extension of the DDM1 by
+a high-order correction term.  The DDM2 is derived for elliptic problems with
+Neumann and Robin boundary conditions, and it is shown to be asymptotically
+second-order accurate in the interface width.  However, the analysis in Paper~E
+is somewhat lacking in that it assumes that the DDM1 is only first-order
+accurate.  In the following sections, we extend the analysis of Paper~E and
+show that the DDM1 is also second-order accurate.  The analysis is shown for
+the steady reaction-diffusion equation with Neumann boundary conditions, but
+the same technique also applies for the corresponding Robin problem.
+
+\section{The DDM for a Neumann problem}
+Consider the steady reaction-diffusion equation with Neumann boundary
+conditions,
+\begin{equation}
+  \begin{alignedat}{2}
+    \lapl u - u  &= f        & \txin D, \\
+    \ndot\grad u &= g \qquad & \txon \partial D,
+  \end{alignedat}
+  \label{eq:ddan}
+\end{equation}
+where $f$ and $g$ are given.  Let $\chi_D$ be the characteristic function of
+$D$,
+\begin{equation}
+  \chi_D = \begin{cases}
+    1 & \text{if $x\in D$,} \\
+    0 & \text{if $x\notin D$.}
+  \end{cases}
+\end{equation}
+The main idea with the diffuse-domain approach is to extend the original
+equation \eqref{eq:ddan} into a larger and regular domain $\Omega\supset D$, as
+depicted in \cref{fig:ddadomain}.  The extension can be written as
+\begin{equation}
+  \div(\chi_D\grad u) - \chi_D u + \text{BC} = \chi_D f,
+  \label{eq:ddm}
+\end{equation}
+where BC is a singular source term that represents the physical boundary
+condition on $\partial\Omega$.

+  \end{tikzpicture}
+  \caption{A regular domain $\Omega$ that contains a complex domain $D$.}
+  \label{fig:ddadomain}
+\end{figure}
+
+The characteristic function is typically approximated by the phase-field
+function,
+\begin{equation}
+  \chi_D \simeq \phi(\vct x,t) = \frac{1}{2} \left( 1
+  - \tanh \left( \frac{3r(\vct x,t)}{\epsilon} \right) \right),
+  \label{eq:characteristic}
+\end{equation}
+where $\epsilon$ is the interface width and $r(\vct x,t)$ is the
+signed-distance function with respect to the boundary $\partial D$, which is
+taken to be negative inside $D$.
+
+The main difficulty with the diffuse-domain approach is the derivation of
+approximations for the boundary condition term BC.  \citet{Li09} give four
+approximations that are shown to converge asymptotically with first order in
+$\epsilon$ to the original equation when $\epsilon$ is decreased.  In the
+following we consider the approximation
+\begin{equation}
+  \text{BC} \simeq |\grad\phi| g.
+  \label{eq:bc1}
+\end{equation}
+If we combine the above approximations \eqref{eq:characteristic} and
+\eqref{eq:bc1}, we get a DDM1 equation for \eqref{eq:ddan},
+\begin{equation}
+  \div\left(\phi\grad u\right) - \phi u +  |\grad\phi| g = \phi f.
+  \label{eq:ddm1}
+\end{equation}
+
+\section{The method of matched asymptotic expansions}
+The following is a brief introduction to the method of matched asymptotic
+expansions, which is used to show that a given diffuse-domain approximation
+converges to the original problem when the interface width is decreased.  More
+details can be found in Paper~E and in \cite{Pego88}.
+
+Let $u$ be some diffuse-domain variable.  The asymptotic convergence of a given
+diffuse-domain approximation can be shown through expansions of the
+diffuse-domain variables in powers of the interface thickness $\epsilon$ in
+regions close to and far from the interface.  For example, the expansions of
+$u$ are
+\begin{align}
+  u(\vct x)        &= \sum_{k=0}^\infty \epsilon^k      u^{(k)}(\vct x), \\
+  \hat u(z,\vct s) &= \sum_{k=0}^\infty \epsilon^k \hat u^{(k)}(z,\vct s),
+\end{align}
+where $u(\vct x)$ and $\hat u(\vct s,z)$ denote the outer and inner expansions,
+respectively.  Here $z$ is a stretched variable,
+\begin{equation}
+  z = \frac{r(\vct x)}{\epsilon},
+\end{equation}
+where $r$ is the signed distance from the point $\vct x$ to $\partial D$ and is
+taken to be negative inside $D$.  Further, $z$ and $\vct s$ form a local
+coordinate system such that
+\begin{equation}
+  \vct x(\vct s,z) = \vct X(\vct s) + \epsilon z\vct n(\vct s),
+\end{equation}
+where $\vct X(\vct s)$ is a parametrisation of the interface, $\vct n(\vct s)$
+is the interface normal vector, and $z$ is a stretched variable.
+
+When the inner and outer expansions are found, they are matched in a region
+where both solutions are valid and where $\epsilon z = \bigo 1$, see
+\cref{fig:regions}.  The outer solution is then evaluated in the inner
+coordinates, which leads to a set of matching conditions that must hold when
+$\epsilon\to 0$.  If we consider $\epsilon$ to be fixed and let $z \to
+\pm\infty$, we get the following asymptotic matching conditions:
+\begin{equation}
+  \label{eq:match1}
+  \zlimpm \hat u^{(0)}(z,\vct s) = u^{(0)}(\vct s),
+\end{equation}
+and as $z \to \pm\infty$,
+\begin{align}
+  \label{eq:match2}
+  \hat u^{(1)}(z,\vct s) &= u^{(1)}(\vct s)
+    + z\ndot\grad u^{(0)}(\vct s) + \smallo 1, \\
+  \begin{split}
+    \hat u^{(2)}(z,\vct s) &= u^{(2)}(\vct s)
+      + z\ndot\grad u^{(1)}(\vct s) \\
+      &\quad + \frac{z^2}{2} (\ndot\grad)\grad u^{(0)}(\vct s)\cdot\vct n
+      + \smallo 1.
+    \label{eq:match3}

+$\partial D$, and that the outer solution is used to obtain the sharp-interface
+equation inside the physical domain $D$.
+
+To show that a given DDM approximation converges with second order, one must
+show that the order-one term of the outer solution of the DDM equation is zero
+in $D$.  As an example, we consider the outer solution of the DDM1 equation
+\eqref{eq:ddm1}, which is
+\begin{equation}
+  \begin{split}
+    \lapl u^{(0)} - u^{(0)} &= f, \\
+    \lapl u^{(1)} - u^{(1)} &= 0, \\
+    \lapl u^{(k)} - u^{(k)} &= 0,\qquad k = 2,3,\dots.
+  \end{split}
+  \label{eq:ddm_outer}
+\end{equation}
+For the solution to be asymptotically second order, that is $u = u^{(0)}
++ \bigo{\epsilon^2}$, we must have that $u^{(0)}$ satisfies the original
+problem \eqref{eq:ddan} and that $u^{(1)}=0$.  Thus the inner expansion must
+yield a boundary condition for $u^{(1)}$ to enforce $u^{(1)}=0$.
+
+\section{Asymptotic analysis of the DDM1 and the DDM2}
+\label{sec:DDM2}
+In Paper~E we present the DDM2, which extends the DDM1 \eqref{eq:ddm1} with
+a high-order correction term,
+\begin{equation}
+  \div\left(\phi\grad u\right) - \phi u +  |\grad\phi| g
+    + r|\grad\phi|\left(f - \kappa  g - \lapls u + u\right) = \phi f.
+  \label{eq:ddm2}
+\end{equation}
+Here $r|\grad\phi|\left(f - \kappa  g - \lapls u + u\right)$ is the
+correction term, $\kappa$ is the curvature of the boundary $\partial D$, and
+$\lapls u$ is the surface Laplacian of $u$, which can be defined as
+\begin{equation}
+  \lapls u \equiv
+  \left( I - \vct n\otimes\vct n \right)
+        \div \left( I - \vct n\otimes\vct n \right)\grad u,
+\end{equation}
+where $I$ is the identity matrix and $\vct n$ is the normal vector.  The
+curvature can be calculated from the phase-field function
+\eqref{eq:characteristic} as
+\begin{equation}
+  \kappa = -\div\frac{\grad\phi}{|\grad\phi|}.
+\end{equation}
+
+In the following, we use the method of matched asymptotic expansions to show
+that the DDM1 \eqref{eq:ddm1} and the DDM2 \eqref{eq:ddm2} are both
+second-order approximations of \eqref{eq:ddan} in $\epsilon$.  First, it is
+easy to see that the outer expansions of both approximations are given by
+\eqref{eq:ddm_outer}.
+
+Next, we consider the inner expansion of the DDM2 \eqref{eq:ddm2}, which is
+\begin{multline}
+  \frac{1}{\epsilon^2}\left(\phi\hat u_z\right)_z
+  + \frac \kappa \epsilon \phi\hat u_z
+  + \phi\lapls \hat u
+  - \phi\hat u \\
+  - \frac 1 \epsilon \phi_z g
+  - z\phi_z\left(\hat u + \hat f - \kappa g - \lapls\hat u\right)
+  = \phi \hat f.
+  \label{eq:ddm_inner}
+\end{multline}
+We expand $\hat u(z,\vct s)$ in powers of $\epsilon$ and collect the lowest
+order terms,
+\begin{equation}
+  \left(\phi\hat u_z^{(0)}\right)_z = 0.
+\end{equation}
+If we integrate over all $z$, we get that $\hat u_z^{(0)} = 0$.  The next order
+terms of~\eqref{eq:ddm_inner} then give
+\begin{equation}
+  \left(\phi\hat u_z^{(1)}\right)_z = \phi_z g,
+\end{equation}
+and again we integrate, which gives that
+\begin{equation}
+  \phi\hat u_z^{(1)} = \phi g + C
+  \label{eq:uz1}
+\end{equation}
+where the constant $C$ must be zero, since $\lim_{z\to\infty}\phi(z) = 0$.  Now
+consider the limit $z\to-\infty$ and use the matching condition
+\eqref{eq:match2} to get
+\begin{equation}
+  \ndot\grad u^{(0)} = g.
+\end{equation}
+Thus $u^{(0)}$ satisfies the original problem at least to first order in
+$\epsilon$.  This shows that both DDM1 and DDM2 are first-order approximations
+of the sharp-interface problem.
+
+To obtain the result for the next order, we need to apply the derivative of
+the matching condition \eqref{eq:match3},
+\begin{equation}
+  \hat u_z^{(2)} = \ndot\grad u^{(1)}
+      + z (\ndot\grad)\grad u^{(0)}\cdot\vct n.
+  \label{eq:match3_z}
+\end{equation}
+Further, we use that $u^{(0)}$ satisfies
+\begin{equation}
+  \lapl u^{(0)} - u^{(0)} = f^{(0)},
+\end{equation}
+and that the Laplacian may be decomposed as
+\begin{equation}
+  \lapl u = (\ndot\grad)\grad u\cdot\vct n + \kappa\ndot\grad u + \lapls u,
+\end{equation}
+to get
+\begin{equation}
+  (\ndot\grad)\grad u^{(0)}\cdot\vct n
+    = u^{(0)} + f^{(0)} - \kappa g - \lapls u^{(0)}.
+  \label{eq:ngradun}
+\end{equation}
+Now insert \eqref{eq:ngradun} into \eqref{eq:match3_z} and use the matching
+condition \eqref{eq:match1} to obtain a modified matching condition,
+\begin{equation}
+  \hat u_z^{(2)} - z\left(\hat u^{(0)} + \hat f^{(0)}
+        - \kappa g - \lapls \hat u^{(0)}\right)
+  = \ndot\grad u^{(1)}.
+  \label{eq:match3_z2}
+\end{equation}
+
+We are now ready to consider the zeroth order terms,
+\begin{multline}
+  \label{eq:o1}
+  \left(\phi\hat u^{(2)}_z\right)_z
+  + \phi\kappa\hat u_z^{(1)}
+  + \phi\lapls \hat u^{(0)}
+  - \phi\hat u^{(0)} \\
+  - z\phi_z\left(\hat u^{(0)}
+      + \hat f^{(0)} - \kappa g - \lapls\hat u^{(0)}\right)
+  = \phi \hat f^{(0)}.
+\end{multline}
+The modified matching condition \eqref{eq:match3_z2} motivates that we subtract
+and add the term
+\[
+  \bigg(z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\bigg)_z
+\]
+to \eqref{eq:o1}, which gives
+\begin{multline}
+  \bigg(\phi\hat u_z^{(2)}
+    - z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\bigg)_z \\
+  + \bigg(z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\bigg)_z \\
+  + \phi\kappa\hat u_z^{(1)}
+  + \phi\lapls \hat u^{(0)}
+  - \phi\hat u^{(0)} \\
+  - z\phi_z\left(\hat u^{(0)}
+      + \hat f^{(0)} - \kappa g - \lapls\hat u^{(0)}\right)
+  = \phi \hat f^{(0)}.
+\end{multline}
+We expand the terms and use \eqref{eq:uz1},
+\begin{multline}
+  \bigg(\phi\hat u_z^{(2)}
+    - z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\bigg)_z \\
+  + \cancel{\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)} \\
+  + z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)_z \\
+  + \cancel{\phi\kappa g
+  + \phi\lapls \hat u^{(0)}
+  - \phi\hat u^{(0)}}
+  = \cancel{\phi \hat f^{(0)}},
+  \label{eq:o2}
+\end{multline}
+or
+\begin{multline}
+  \bigg(\phi\hat u_z^{(2)}
+    - z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\bigg)_z \\
+  + z\phi\left(\cancel{\hat u_z^{(0)}} + \hat f_z^{(0)}
+      - \cancel{(\kappa g)_z}
+      - \cancel{\lapls \hat u_z^{(0)}}\right) = 0.
+\end{multline}
+If we assume that $\hat f_z^{(0)}$, we get
+\begin{equation}
+  \bigg(\phi\hat u_z^{(2)}
+    - z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\bigg)_z = 0.
+  \label{eq:o3}
+\end{equation}
+Finally, we integrate the left-hand side and take the limit,
+\begin{align}
+  \nonumber
+  \eint{\bigg(\phi\hat u_z^{(2)}
+    &- z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+     - \lapls \hat u^{(0)}\right)\bigg)_z} \\
+  \nonumber
+  &= \ejmp{\phi\hat u_z^{(2)}
+    - z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)} \\
+  \nonumber
+  &= -\zlimm{\left(\hat u_z^{(2)}
+    - z\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\right)} \\
+  &= -\ndot\grad u^{(1)},
+\end{align}
+thus
+\begin{equation}
+  \ndot\grad u^{(1)} = 0.
+  \label{eq:ngradu1}
+\end{equation}
+Combined with \eqref{eq:ddm_outer}, this shows that $u^{(1)}=0$, and so DDM2
+converges asymptotically with second order to the original problem.
+
+The analysis above also holds for DDM1, except instead of \eqref{eq:o3} we get
+\begin{multline}
+  \bigg(\phi\hat u_z^{(2)}
+    - z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\bigg)_z \\
+  = - z\phi_z \left(\hat u^{(0)} + \hat
+        f^{(0)} - \kappa g - \lapls \hat u^{(0)}\right)
+  = - z\phi_z D,
+  \label{eq:o4}
+\end{multline}
+where $D$ is independent of $z$.  Now we use that
+\begin{equation}
+  \phi_z = -(3 \sech^2 3z)/2,
+\end{equation}
+which follows from the definition of the phase-field function
+\eqref{eq:characteristic}.  We integrate the right-hand side, which gives
+\begin{equation}
+  D\eint{z\phi_z} = -D\frac 3 2\eint{z\sech^2 3z} = 0.
+\end{equation}
+Thus DDM1 is also second order in $\epsilon$.
+
+The difference between the DDM1 and the DDM2 is therefore that the correction
+term with the DDM2 directly cancels the term on the right-hand side in
+\eqref{eq:o4}.  This should give an increase of accuracy, but the convergence
+order remains the same.
+
+The analysis for the corresponding Robin problem is essentially the same as the
+above.  In Paper~E, the DDM1 and DDM2 are compared for several elliptic
+problems with both Neumann and Robin boundary conditions.  The results of
+Paper~E show that the correction term in the DDM2 leads to an increase of
+accuracy and that both DDM1 and DDM2 converge with second-order accuracy.
+
+\section{Summary}
+In this chapter, we have given a brief introduction to the diffuse-domain
+method (DDM).  We considered a steady reaction-diffusion equation with Neumann
+boundary conditions \eqref{eq:ddan} and two DDM approximations:  DDM1
+\eqref{eq:ddm1} and DDM2 \eqref{eq:ddm2}.  The DDM2 is an extension of DDM1 by
+a high-order correction term, and was first derived in Paper~E.
+
+Next, we gave an outline of the method of matched asymptotic expansions, and we
+used it to show that both the DDM1 and the DDM2 converged asymptotically with
+second order in the diffuse-interface width to the original equation
+\eqref{eq:ddan}.  The analysis shows that the correction term in the DDM2 leads
+to a cancellation in the asymptotic expansions.  By doing the integration, we
+see that this cancellation is not necessary for obtaining the second order
+convergence.

+\section[Paper A]{Paper A:  Calculation of interface curvature with the
+  level-set method}
+Karl Yngve Lervåg.  Published in \emph{MekIT'11 - 6th National Conference on
+  Computational Mechanics, Trondheim}, 2011.  ISBN: 978-82-519-2798-7.
+
+In this paper I address a problem with the calculation of the interface
+curvature with the level-set method, cf.\ \cref{sec:curvature}.  The curvature
+can be calculated from the level-set function, $\phi$, as
+\begin{equation}
+  \kappa = \div\vct n = \div\frac{\grad\phi}{|\grad\phi|}.
+\end{equation}
+It is typically discretized by standard methods such as the second-order
+central-difference scheme (CD-2), and interpolated to the interface where
+needed \cite{Osher88,Kang00,Osher03}.  However, the level-set function as
+a signed-distance function will tend to have kinks where its gradient is
+discontinuous.  The standard methods may lead to large errors in the curvature
+close to these regions, which in turn may lead to errors in the surface tension
+force.
+
+The main contribution of this paper is a new curve-fitting discretization
+method (CFDM) for the curvature (see \cref{sec:curvature-curve-fitting}).  The
+method is based on the approach developed by \citet{Macklin06}.  It differs in
+that it uses a cubic Hermite spline parametrisation of the interface, and that
+the curvature values are calculated on the grid and then interpolated to the
+interface as opposed to using a localised grid centred at the interface as in
+\cite{Macklin06}.

+\end{figure}
+
+The CFDM is tested and compared with the CD-2 for two test cases, and it is
+shown to yield better results in both cases.  \Cref{fig:A1} shows one of these
+results, where the calculated curvature values are compared.  In the example,
+a cylindrical drop impacts on a liquid film.  The figure shows that the CD-2
+leads to large errors in the curvature calculations in the kink regions, that
+is, the red and dark blue regions in \cref{fig:A1a} near the liquid film.
+These errors are not present with the new method, cf.\ \cref{fig:A1b}.

+\section[Paper B]{Paper B:  Curvature calculations for the level-set method}
+Karl Yngve Lervåg and Åsmund Ervik.  Published in \emph{ENUMATH 2011}
+proceedings volume, Springer, 2013.  ISBN: 978-3642331336.
+
+This paper is a continuation of Paper A.  The main contribution in this paper
+is a comparison of different methods for calculating the curvature in a robust
+manner with the level-set method in the kink regions.  In particular, the
+CFDM\footnote{The method is called LM in the paper.  Here CFDM is used, in
+  order to be consistent with the rest of the thesis.} that was presented in
+Paper A is compared with Macklin and Lowengrub's method (MLM)~\cite{Macklin06}.
+In addition, the method is compared with the second-order central-difference
+scheme (CD-2) and the more recent method presented by \citet{Salac08}, here
+called Salac and Lu's method (SLM).
+
+The main result in the paper is shown in \cref{fig:B1}, which shows
+a comparison of the methods for a case where two drops collide in a 2D shear
+flow.  In particular, it shows snapshots of the evolution of the interfaces and
+the curvature at times $t=\SI{2.30}{s}$, $t=\SI{2.75}{s}$, and
+$t=\SI{3.10}{s}$.  The results show that all of the improved methods, that is
+MLM, CFDM, and SLM, handle the kink region in a more reliable manner than CD-2.
+The reason that the result with MLM differs from those with CFDM and SLM might
+be that it uses a localised grid centred at the interface to calculate the
+curvature, which means that it does not need to use interpolation of the
+curvature from the grid to the interface.  Note that the difference is mainly
+that the MLM results in slightly earlier coalescence in the given case.

+\section[Paper C]{Paper C:  Calculation of the interface curvature and normal
+  vector with the level-set method}
+Karl Yngve Lervåg, Bernhard Müller, and Svend Tollak Munkejord.  Published in
+Computers and Fluids, volume 84 (2013), 218--230.
+
+Paper A presented the curve-fitting discretization method (CFDM) for the
+calculation of the curvature with the level-set method.  The method was
+designed to be robust in the calculation of the curvature in kink regions, that
+is regions where the gradient of the level-set function is not smooth.  This
+paper presents the details of the CFDM and applies it to the calculation of
+both the curvature and the normal vector.
+
+In the paper we compare the CFDM with the second-order central-difference
+scheme (CD-2) for several test cases.  In the first case, we consider the
+curvature calculations for a nontrivial geometry that includes some kink
+regions.  This is a static test case with no flow, and the results show that
+the CD-2 leads to large errors for the curvature calculations in areas close to
+kink regions and that these errors are not present with the CFDM.
+
+In the following two cases, we consider the collision of two drops in a 2D
+shear flow and in an axisymmetric flow.  These cases show that the errors in
+the curvature calculations in the kink regions with the CD-2 lead to errors in
+the pressure that prevents coalescence.  These errors are prevented with the
+CFDM.  The curvature and the evolution of the interfaces for the axisymmetric
+case are shown in \cref{fig:C1,fig:C2}.  As in the earlier results of Papers
+A and B, the figures show that the errors in the curvature calculation with
+CD-2 prevent coalescence, in this case leading to a slower coalescence process.

+\section[Paper D]{Paper D:  A robust method for calculating interface curvature
+  and normal vectors using an extracted local level set}
+Åsmund Ervik, Karl Yngve Lervåg, and Svend Tollak Munkejord.  Submitted to
+Journal of Computational Physics, 2013.
+
+In this paper we present an alternative method for the calculation of the
+curvature and the normal vector of an interface with the level-set method in
+kink regions, hereafter called the local level-set extraction (LOLEX) method.
+The method is based on a method presented by \citet{Salac08} (SLM), who handle
+the kink region by extracting different bodies of a domain into separate
+level-set functions.  This procedure removes most of the kink regions, but it
+does not handle kink regions that are due to complex interfaces of single
+bodies.  Our method extends the SLM by making it local.  That is, we only
+consider the local area around the point for which we are calculating the
+curvature or the normal vector.  This leads to a method that is more generally
+applicable, as shown in \cref{fig:D1}.  The figure shows a comparison between
+the LOLEX method, the SLM, and the standard central differences (CD-2).  CD-2
+leads to curvature spikes at the kink regions, as explained in
+\cref{sec:curvature}.  The SLM gives a better result for the kink regions
+around the rightmost disc.  However, since the other two discs are connected to
+each other and to the film, they are considered to be the same body and are
+extracted into the same level-set function.  Several kink regions are therefore
+not removed.  Since the LOLEX method only considers the local area, as
+explained in \cref{sec:lolex}, it is able to handle all the kink regions in
+a robust manner.

+    is disjoint.  The color indicates the curvature; white is zero, blue is
+    negative and red is positive.}
+  \label{fig:D1}
+\end{figure}
+
+The LOLEX method has proven to be a good alternative to the CFDM presented in
+Paper A.  Its main advantages are that it does not rely on complex algorithms
+as used in the CFDM or by \citet{Macklin06}, and that the method easily extends
+to 3D as demonstrated in the paper in Section~4.4.
+
+In the previous papers A--C, we used the DP1 projection method by
+\citet{Hansen05}.  In this paper we instead used the more standard Chorin
+projection method.  These methods differ in that the DP1 assumes
+\begin{equation}
+  \div\left(\pdt{\vct u}\right) = 0.
+\end{equation}
+When compared with the Chorin method, this assumption becomes equivalent to
+assuming that $\div\vct u^{n} = 0$ in \eqref{eq:PoissonChorin}.  That is, the
+DP1 assumes that the initial velocity field is divergence free.  We have found
+that the DP1 works well in most cases, but that it is less robust than the
+Chorin method.  In particular, the Chorin method is not equally affected by
+errors in the curvature calculations in kink regions.  In other words, the
+difference between using a standard discretization and an improved
+discretization of the curvature is smaller with the Chorin method than with the
+DP1.
+
+The LOLEX method is used for several test cases and compared with CD-2.  The
+results indicate that even though we use the Chorin projection method, the
+LOLEX method outperforms CD-2 in all cases.  Further, the results agree well
+with experiments, except for time instants, as shown in \cref{fig:D2}.  The
+exact reason why the time instants do not match is not known, but one reason
+may be that the initial condition of the numerical simulation did not match the
+corresponding state of the experiment.

+    from~\cite{Zhao11}, Copyright (2011), with permission from Elsevier.}
+  \label{fig:D2}
+\end{figure}
+
+When we study the drop-film collision processes, an important consequence of
+the error in the curvature calculation is a loss of kinetic energy.  This can
+be seen in \cref{fig:D3}, which compares the LOLEX method with CD-2 at two
+different stages of the collision process.  The figure also compares two
+different frequencies of reinitialization of the level-set function:  Every
+7 time steps ((a) and (c)) and every single time step ((b) and (d)).  The
+figure shows that the error in the curvature calculation with CD-2 leads to
+a shorter neck, as seen in \cref{fig:D3}, (c) and (d).  The error is larger for
+the higher frequency of reinitialization.  The results indicate that CD-2 leads
+to a loss of kinetic energy during the collision process when compared with the
+LOLEX method.  The LOLEX method is not significantly affected by the amount of
+reinitialization, and the kink region does not affect the curvature
+calculation, cf.\ \cref{sec:lolex}.  Thus the pressure field is more sensible,
+as seen in \cref{fig:D3} (a) and (b).  Finally, we remark that some authors
+have noted \cite{Blanchette06} that the height of the neck and the dynamics of
+the capillary waves are important factors for the partial coalescence
+mechanism, which implies that the correct calculation of the curvature is
+important to capture the correct physical behavior.

+\section[Paper E]{Paper E:  Towards a second-order diffuse-domain approach for
+  solving PDEs in complex geometries}
+Karl Yngve Lervåg and John Lowengrub.  Submitted to Communications in Math.
+Sciences, 2013.
+
+\citet{Li09} developed a diffuse-domain method for solving partial-differential
+equations (PDEs) inside complex, dynamic geometries with Dirichlet, Neumann,
+and Robin boundary conditions.  This method is in the following referred to as
+DDM1.  They use the diffuse-domain approach~\cite{Kockelkoren03}, where the
+geometry is represented implicitly and the sharp boundary is replaced by
+a diffuse layer with a fixed interface width.  The original governing equations
+are then reformulated on a larger, regular domain and the boundary conditions
+are incorporated via singular source terms.  The method of matched asymptotic
+expansions is used to show that the reformulated problem converges
+asymptotically to the original problem.
+
+In the present paper, we use the method of matched asymptotic expansions to
+extend the DDM1 with include a high-order correction term in the diffuse
+formulation, cf.\ \cref{sec:DDM2}.  The extension is derived for elliptic
+problems with Neumann and Robin boundary conditions, where the correction term
+is shown to yield an asymptotically second-order accurate approximation of the
+original problem.  The new method is referred to as the DDM2.
+
+The DDM1 and DDM2 are compared for a selection of test problems.  The resulting
+equations were discretized by standard second-order central-difference schemes
+on uniform grids, and solved by a multigrid method.  A red-black Gauss-Seidel
+type iterative method was used as a smoother, see \cite{Wise07}.
+
+In addition to the comparison of DDM1 and DDM2, we compared two different
+approximations of the boundary conditions.  These correspond to different
+diffuse-interface surface delta functions, and for the Neumann boundary
+conditions they are
+\begin{equation}
+  \text{BC1} = |\grad\phi| g,
+\end{equation}
+and
+\begin{equation}
+  \text{BC2} = \epsilon|\grad\phi|^2 g.
+\end{equation}
+The approximations are similar for the Robin boundary condition, although here
+it was found that only BC1 resulted in a valid asymptotically second-order
+accurate DDM2.
+
+Our results show that the global accuracy and convergence of DDM2 is better
+than DDM1, however both methods perform well and the global convergence rate is
+around two for each.  The error was measured as the L$_2$ norm of the
+difference between an analytic solution and the solution $u_\epsilon$ for
+a given interface width, $\epsilon$.
+
+\Cref{fig:E1,fig:E2} show two of the results, the first one with the Neumann
+boundary conditions and the second with the Robin boundary condition.  The
+results indicate that DDM2 performs slightly better than DDM1.  They also show
+that the approximation BC1 gives more accurate results than BC2.  In
+particular, we found that with BC2 we needed much finer grids to obtain
+convergence for a given $\epsilon$.  For the smallest values of $\epsilon$ we
+were not able to refine the grids enough to obtain valid results.

+\chapter{Conclusions and outlook}
+\label{chap:conclusions}
+This thesis has considered two different problems:  The discretization of
+interface curvature and normal vectors with the level-set method and
+a diffuse-domain approach for solving partial-differential equations (PDEs) in
+complex domains.  In the following, some general concluding remarks and
+recommendations for further work are given.
+
+\section*{Conclusions}
+The first part of the thesis considered the modelling of incompressible
+two-phase flow.  The main motivation was to study two-phase flow phenomena that
+are relevant for compact heat exchangers, such as drop-drop and drop-film
+collisions.  In particular, the thesis addressed a challenge with the
+calculation of interface curvature and normal vectors with the level-set
+method.  Two methods were presented to handle the discretization in the kink
+regions: A curve-fitting discretization method (CFDM) and a local level-set
+extraction (LOLEX) method.  Both methods were shown to be robust in the kink
+regions, where the standard central-difference scheme (CD-2) fails.  Of these
+methods, the LOLEX method is the preferred method, because it relies on a less
+complicated algorithm that easily extends to 3D.
+
+CD-2 and the LOLEX method were used for simulations of drop-film collisions
+that were compared with experiments.  The results showed that CD-2 leads to
+errors in the curvature that cause unphysical pressure spikes during the
+coalescence.  The errors are shown to lead to a dissipation of kinetic energy
+during the collision and to a slower coalescence process.  The LOLEX method was
+shown to prevent these unphysical pressure spikes, and to produce to more
+accurate results.
+
+The second part of the thesis considered the diffuse-domain approach for
+solving PDEs in complex domains.  The main contribution, presented in Paper~E,
+was the derivation of an asymptotically second-order diffuse-domain method
+(DDM2) for solving elliptic problems in complex geometries with Neumann and
+Robin boundary conditions.  The new method is an extension by a high-order
+correction term of the method presented in \cite{Li09}, here called DDM1.  The
+DDM1 and DDM2 were compared, and the results indicated that the DDM2 was
+slightly better than the DDM1.
+
+The thesis has expanded on the results of Paper~E with a new asymptotic
+analysis that shows that DDM1 is in fact also asymptotically second order.
+This analysis helps to explain why the performance of DDM2 presented in Paper~E
+is only slightly better than that of DDM1.  As such, the new analysis leads to
+a better understanding of the DDM1 and the DDM2.
+
+\section*{Outlook}
+The following gives an outline of some possibilities for future work.
+\begin{itemize}
+  \item A natural continuation of this work is to perform more in-depth
+    comparisons of simulations with experiments for the drop-film collision
+    phenomenon that was started in Paper~D.  In addition, it would be
+    interesting to study other two-phase flow phenomena that are relevant for
+    heat-exchanger processes, for instance drop-drop collisions or flow across
+    tube bundles.  The latter requires the treatment of more complex boundaries,
+    which can be handled either with the diffuse-domain method or other methods
+    from the literature.
+  \item Paper~C gave a short comparison of the standard discretization method
+    (CD-2), the direction-difference scheme (DDS), and the curve-fitting
+    discretization scheme (CFDM) applied to the calculation of the normal
+    vectors.  The results showed that the CD-2 leads to inaccurate results in
+    the kink regions.  The DDS gives robust and accurate results in most cases,
+    but an example is given where only the CFDM yields an accurate result.
+    However, the impact of inaccurate calculations of the normal vector should
+    be investigated in more detail.  The normal vector is used both for the
+    solution of the level-set equations \eqref{eq:ls_adeq},
+    \eqref{eq:ls_velextr}, and \eqref{eq:ls_reinit}, and for the calculation of
+    the interface jumps \eqref{eq:jump_pressure} and \eqref{eq:jumptens}, so
+    one can expect that large errors in the calculation of the normal vector
+    may lead to large errors in the numerical solution.  This warrants
+    a further study.
+  \item Mass and heat transfer are obviously an important part of the
+    heat-exchanger processes.  The models that have been used in this thesis
+    should therefore be expanded with additional models for heat transfer and
+    mass transfer to enable the simulation of more relevant phenomena.
+  \item The DDM2 was only derived for problems with Robin and Neumann boundary
+    conditions.  If possible, it should be extended to also work with Dirichlet
+    boundary conditions.
+  \item As explained in Paper~E, we found that we were unable to solve the
+    discrete system of equations when the surface Laplacian part of the
+    correction term for the DDM2 was included.  A further investigation of this
+    problem should be done, and stable numerical methods to solve the full DDM2
+    equations should be developed.
+  \item The diffuse-domain approach is a promising method for solving problems
+    in complex and confined geometries with standard tools and methods.
+    \citet{Aland10} provide a diffuse-domain formulation of the Navier-Stokes
+    Cahn-Hilliard equations for incompressible two-phase flow and use it to
+    compute two-phase flow in both complex and confined geometries.  However,
+    they do not provide an asymptotic analysis of the reformulated equations to
+    show that the system converges.  Such an analysis would be interesting, in
+    particular to verify that the equations do converge to the original problem
+    when the interface width is decreased.
+  \item Finally, it would be interesting to develop a second-order
+    diffuse-domain formulation for the incompressible Navier-Stokes equations.
+    A starting point would be to use the results and techniques from this
+    thesis and Paper~E.

+\chapter{Introduction}
+This thesis considers the mathematical modelling and numerical computation of
+two-phase flows.  It focuses on developing more robust numerical methods to
+calculate the curvature and the normal vector of the interface between the two
+phases.  In addition it considers a diffuse-domain method for solving partial
+differential equations in complex geometries, and it derives an asymptotically
+second-order method for elliptic problems.
+
+\section{Background and motivation}
+Two-phase flows are particular examples of multiphase flows of gas and liquid
+with an interface that separates the two phases.  In the pedantic sense,
+two-phase flow is flow of a single fluid that occurs as two different phases,
+for example steam and water.  However, it is common to be more general, and in
+this thesis we use the term two-phase flow also for immiscible mixtures of
+different fluids, such as water and oil.
+
+Two-phase flows are crucial to a large amount of processes, both in nature and
+in industry.  Examples range from weather phenomena, such as rain drops falling
+through air, to industrial processes, for instance the separation of water from
+oil.  In general, multiphase flow phenomena influence any process where liquids
+and gases are involved.  In the oil and gas industry, most processes are
+two-phase or multiphase flow processes.  Needless to say, the understanding of
+these phenomena is fundamental in the development of new or improved processes.
+
+Consider the international trade of liquefied natural gas (LNG), which is
+a particular branch of the oil and gas industry that has undergone an
+exceptional growth in the last decades.  There is a strong focus both in Norway
+and internationally on producing LNG on large floaters
+(FLNG)\footnote{FLNG facilities do not yet exist, although a facility is under
+  development by Royal Dutch Shell~\cite{Prelude1}.  The construction of this
+  facility was started in 2012, and the first drilling is stated to commence in
+  2013~\cite{Prelude2}.}.  There are a number of both environmental and
+economic advantages of such FLNG facilities.  In particular, FLNG facilities
+would remove the need of long pipelines from the gas fields to the shore, there
+would be no requirement for compression units to pump the gas to the shore, and
+one would not need to construct onshore production facilities.  This would
+significantly reduce the environmental footprint, and would help preserve
+marine and coastal environments.  Since an FLNG facility can be moved to a new
+location when a field has been depleted, it would make it economically viable
+to open up new business opportunities to develop offshore gas fields that would
+otherwise remain stranded.
+
+Moving the LNG production to an offshore facility presents a demanding set of
+challenges.  A particular challenge is that the elements of a conventional LNG
+facility need to fit into an area roughly one quarter the original size.  Heat
+exchangers are among the main challenges in the design and operation of LNG
+plants \cite{Hesselgreaves01}.  Compact and efficient heat exchangers are
+needed to obtain an energy efficient plant with low emissions.  More optimized
+designs require more accurate tools for design and operation.  Such tools can
+only come as a result of an improved physical understanding of the complex
+two-phase flows occurring in the heat exchangers.  This can be achieved by more
+detailed mathematical modelling, together with dedicated laboratory
+observations, cf.\ \cite{Olsen07}.
+
+\section{Overview of methods for two-phase flow simulations}
+In the following, a brief overview is given of different methods for modelling
+two-phase flows where the interface location is known.  In particular, we focus
+on methods that handle the interface evolution.  For more in-depth reviews, see
+for instance \cite{Cristini04,Scardovelli99,Sethian03}.
+
+Interface propagation methods comprise a range of methods that are often
+categorised as either front tracking or front capturing.  Front-tracking
+methods use Lagrangian particles to track the interface
+explicitly~\cite{Tryggvason01}, while front-capturing methods use an Eulerian
+approach to capture the interface implicitly.  Examples of the latter are
+volume-of-fluid methods~\cite{Scardovelli99,Tryggvason11}, phase-field
+methods~\cite{Anderson98,Jacqmin99,Lowengrub98}, and level-set
+methods~\cite{Osher03}.
+
+The main advantages of front-tracking methods are their inherent accuracy and
+that topological changes do not occur without explicit action.  Hence,
+unphysical numerical reconnection does not occur.  This means that if front
+tracking is used for the simulations of two drops that collide, these drops
+will not coalesce due to numerical reconnection or merging.  However, the
+handling of topological changes are challenging, in particular in three
+dimensions~\cite{Shin02}.  Also, there are some issues of numerical
+instabilities, as discussed by \citet{Sethian85} and \citet{Osher88}.
+
+The volume-of-fluid method utilizes a volume-fraction function whose values
+represent the characteristic function of one of the fluid domains.  Its values
+are zero or one, except in those cells cut by the interface.  A considerable
+advantage of the volume-of-fluid method is that it conserves the mass of both
+fluids well.  However, the reconstruction of the interface from volume
+fractions is not simple, and computation of geometric quantities such as the
+interface curvature is not straightforward.  Also, spurious bubbles and drops
+may be created, cf.\ \cite{Lafaurie94}.
+
+The phase-field methods treat the interface in a diffuse manner, where the
+fluid properties, such as density and viscosity, change rapidly but smoothly
+across the interface.  These methods typically solve the coupled
+Cahn-Hilliard/Navier-Stokes equations, where the Cahn-Hilliard equation is
+based on the free energy of an interface~\cite{Cahn57}.  Through this energy
+formulation, one can model more advanced interface physics such as van der
+Waals interactions, electrostatic forces, and fluids with varying
+miscibilities.  However, the phase-field methods require that one resolves very
+small length scales at the interfaces.  This poses a severe restriction on the
+applicability of phase-field methods for two-phase flow, where the length
+scales of the flow are generally much larger than those of the interface.
+
+In this thesis, we have used the level-set method~\cite{Osher88}, which
+implicitly captures the interface as an isocontour of a function defined in the
+entire domain.  The main motivation of this choice is both that the level-set
+method handles topological changes of evolving interfaces automatically,
+cf.~\citet{Sethian03}, and that it is relatively straightforward to implement.
+
+It should be noted that the automatic handling of topological changes is not
+based on physical principles.  For instance, when two interfaces approach each
+other and their distance becomes less than the spacing of the grid, the
+level-set method can no longer resolve both interfaces and so they are merged.
+An important consequence is that the level-set method does not model the
+physics involved in the coalescence process, and in particular in the smaller
+scales of the film-drainage process.  This process involves a wide range of
+length scales, varying from the nanometer scale where van der Waals force are
+active to the length scales of the external flow.  Some effort has been made to
+include the effects of the smaller scales in front-capturing methods,
+cf.~\cite{Nobari96,Tryggvason10}.  Recently, \citet{Kwakkel13} presented
+a level-set/volume-of-fluid method that is coupled with a film-drainage model
+that predicts if and when two colliding droplets will coalesce.  To prevent the
+numerical coalescence, each droplet has its own locally defined level-set
+function.
+
+The level-set method has been used to model several diverse phenomena,
+such as tumour growth~\cite{Macklin06,Macklin05,Macklin08}, propagation of
+wildland fire~\cite{Mallet09}, and computer RAM production~\cite{Melicher08}.
+For a good and thorough introduction to the level-set method, see
+\cite{Osher03}.
+
+A weakness of the level-set method is that it does not conserve the mass of the
+two fluids, in particular in areas of low resolution and/or high curvature.
+Different approaches have been developed to overcome this disadvantage, for
+example the conservative level-set method~\cite{Olsson05,Olsson07}, the
+particle level-set method~\cite{Enright02}, or the coupled
+level-set/volume-of-fluid method~\cite{Sussman00}.
+
+When we use the level-set method to capture the interface for immiscible and
+incompressible two-phase flow simulations, there will be a sharp change in the
+density and viscosity across the interface.  In this thesis we use the
+ghost-fluid method~\cite{Fedkiw99}, which is a sharp-interface method where the
+jumps are included in the spatial discretizations in a sharp manner.  An
+alternative method is the continuous surface-force method introduced by
+\citet{Brackbill92}, where the density and the viscosity are smeared out across
+the interface through a smoothed Heaviside function.
+
+\clearpage
+\section{Goal and contribution of the present thesis}
+The main goal of the PhD project has been to develop fundamental knowledge of
+two-phase flow phenomenon that are relevant for compact heat exchangers.
+
+In order to do detailed theoretical studies of phenomena that are relevant for
+compact heat exchangers, we need to consider two-phase flows with mass and heat
+transfer in confined and complex geometries.  One such relevant phenomenon is
+the drop-film collision process \cite{Zhao09}.  Even when restricted to
+isothermal and immiscible flows, this simple phenomenon remains a challenge.
+When the level-set method is used to capture the interface, one must be
+particularly careful about how one calculates the interface curvature and
+normal vector.  For instance, when two drops are in near collision there is
+a kink region in the level-set function between the drops, where the gradient
+is discontinuous, see \cref{fig:curvature-problem}.  This discontinuity may
+lead to large errors in the curvature and the normal vector if it is not taken
+into account in the discretization stencils.

+
+As a step towards computing two-phase flow simulations in confined geometries,
+the thesis has considered the diffuse-domain method~\cite{Li09}.  This is
+a method where partial-differential equations in complex domains are extended
+into larger, regular domains with the use of diffuse approximations of the
+physical boundaries.  The approximations converge asymptotically to the
+original problem when the width of the diffuse boundary is reduced.  With this
+method one can use standard numerical methods to solve equations that
+incorporate complex boundaries.
+
+The main contributions of the present thesis are two new methods to calculate
+the curvature and normal vector in a robust manner with the level-set method.
+These methods are shown to yield more accurate calculations of drop-film and
+drop-drop collisions.  The methods are compared with standard methods and with
+other methods from the literature.
+
+In addition, the thesis presents an extension of a diffuse-domain method by
+a high-order correction term for the solution of elliptic problems in complex
+geometries.  New analysis provided in the thesis improves the understanding of
+the diffuse-domain method, and the derived method is shown to be more accurate
+than the existing diffuse-domain method.
+
+\section{Outline of the thesis}
+The thesis is organised as follows: \Cref{chap:two-phase-flow} gives a brief
+overview of the derivation of the governing equations for two-phase flow.  It
+includes a consideration of the fluid-fluid interface conditions and the
+derivation of a simplified jump tensor for the viscous term at the interface.
+
+\Cref{chap:numerical-methods} gives a detailed description of the numerical
+methods that are used to solve the two-phase flow equations.  In particular, it
+describes the level-set method, which is used to capture the interfaces,
+projection methods that are used to solve the Navier-Stokes equations, and the
+spatial and temporal discretization schemes.  At the end of the chapter, an
+overview of the novel discretization methods for the curvature and the normal
+vector is given.
+
+\Cref{chap:diffuse-domain} gives a short introduction to the diffuse-domain
+method for an elliptic problem with Neumann boundary conditions.  It introduces
+the high-order correction term, and shows that the new method converges
+asymptotically with second-order to the original problem.  The chapter presents
+new analysis that shows that the correction term is not necessary for
+second-order convergence.
+
+In \cref{chap:contributions} the main results of the contributed papers A--E
+are summarized, and the author's contributions are highlighted.  Finally,
+\cref{chap:conclusions} gives concluding remarks and provides an outlook for
+future work.

+Full-text versions of the research papers A--E are provided in the Appendices

+\chapter{Governing equations for two-phase flow}
+\label{chap:two-phase-flow}
+In this chapter we will give a brief overview of the derivation of the
+governing equations for two-phase flow.  We begin with a consideration of the
+Navier-Stokes equations for single-phase flow.  We then introduce a singular
+surface-force term and derive the Navier-Stokes equations for two-phase flow.
+Finally, we use the Navier-Stokes equations for two-phase flow to derive jump
+conditions at the interface between the phases.
+
+\section{The Navier-Stokes equations for single-phase flow}
+The following is a brief derivation of the Navier-Stokes equations for
+single-phase flows.  For a more thorough derivation of these equations, see for
+instance \citet[§4 and §5]{Aris89} or \citet[Chapter~4]{White03}.
+
+We consider a single-phase, viscous flow in some domain $\Omega$ with boundary
+$\partial\Omega$.  When temperature effects are neglected the flow is described
+by the Cauchy equation
+\begin{equation}
+  \label{eq:cauchy_equation}
+  \rho\left(\cd{\vct u}\right) = \div\tenstr+\rho\vct f,
+\end{equation}
+and the mass conservation equation,
+\begin{equation}
+  \label{eq:cons_of_mass}
+  \pdt\rho + \div(\rho\vct u) = 0.
+\end{equation}
+Here $\rho$ is the fluid density, $\vct u$ is the flow velocity, $t$ is time,
+$\tenstr$ is the stress tensor, $\vct f$ denotes body forces, and $\del$ is
+used to denote the gradient and divergence operators.  The stress tensor for
+Newtonian fluids with zero bulk viscosity is
+\begin{equation}
+  \tenstr = -p\tenI + 2\mu\tenD - \frac 2 3\mu (\trace\tenD) \tenI,
+  \label{eq:viscous_stress_tensor}
+\end{equation}
+where $p$ is the pressure, $\tenI$ is the identity tensor, $\mu$ is the dynamic
+viscosity, and $\trace\tenD$ denotes the trace of the strain-rate tensor
+$\tenD$,
+\begin{equation}
+  \tenD = \frac{1}{2}\left( \grad\vct u + (\grad\vct u)^T \right).
+  \label{eq:deformation_tensor}
+\end{equation}
+For incompressible flow, the mass-conservation equation reduces to
+\begin{equation}
+  \label{eq:navier-stokes-1}
+  \div\vct u = 0,
+\end{equation}
+that is, the velocity field must be divergence free.  If we further assume that
+the viscosity is constant, then it follows that the divergence of the stress
+tensor reduces to
+\begin{equation}
+  \label{eq:stress_tensor}
+  \div\tenstr = -\grad p + \mu\lapl\vct u,
+\end{equation}
+and so the Cauchy equation \eqref{eq:cauchy_equation} becomes
+\begin{equation}
+  \rho\left(\cd{\vct u}\right) = -\grad p + \mu\lapl\vct u + \rho\vct f.
+  \label{eq:navier-stokes-2}
+\end{equation}
+Equations \eqref{eq:navier-stokes-1} and \eqref{eq:navier-stokes-2} are the
+incompressible Navier-Stokes equations for single-phase flow with constant
+viscosity.
+
+\section{The Navier-Stokes equations for two-phase flow}
+We now consider an immiscible two-phase flow of two Newtonian fluids, each with
+its own viscosity and density.  We let $\Omega_1$ and $\Omega_2$ denote the
+domains occupied by fluid 1 and fluid 2, respectively, and let the interface
+between the fluids be denoted by $\Gamma$.  Then $\Omega
+= \Omega_1\cup\Omega_2$ and $\partial\Omega
+= (\partial\Omega_1\cup\partial\Omega_2)\setminus\Gamma$ are the fluid domain
+and its boundary, respectively.  See \cref{fig:domain} for an illustration of
+a two-phase flow domain.

+  \caption{An illustration of a two-phase flow domain.  The interface $\Gamma$
+    separates the two phases $\Omega_1$ and $\Omega_2$.}
+  \label{fig:domain}
+\end{figure}
+
+The extension of the single-phase model to account for two fluids can be made
+by adding a singular surface-force term to represent the effects of surface
+tension between the fluids.  We assume that the surface tension is constant, in
+which case the singular surface force can be defined as
+\begin{equation}
+  \funssf(\vct x,t)
+  = \int_{\Gamma}\sigma\kappa\vct n\delta(\vct x - \vct x_I(\vct s))\dif\vct s,
+  \label{eq:ssf}
+\end{equation}
+where $\sigma$ is the surface tension, $\kappa$ is the local curvature, $\vct
+n$ is the normal vector, $\delta$ is the Dirac delta function, and $\vct
+x_I(\vct s)$ is a parametrisation of the interface.  Thus the Navier-Stokes
+equations for immiscible and incompressible two-phase flow are
+\begin{align}
+  \label{eq:ns1}
+  \div\vct u &= 0, \\
+  \label{eq:ns2}
+  \rho\left(\cd{\vct u}\right) &= -\grad p + \mu\lapl\vct u
+    + \rho\vct f + \funssf.
+\end{align}
+
+\section{Fluid-fluid interface conditions}
+The surface-tension force and the jump in viscosity and density across the
+interface $\Gamma$ lead to a set of interface conditions that must be satisfied
+along the interface $\Gamma$.  The following is a brief derivation of these
+conditions.
+
+First, we only consider flows where there is no mass transfer, which implies
+that
+\begin{equation}
+  \jmp{\vct u}\cdot\vct n = 0,
+\end{equation}
+where $\jmp{\cdot}$ denotes the jump at the interface, for instance $\jmp{\mu}
+= \mu_2 - \mu_1$.  Further, for viscous flows there is no slip at the
+interface, and thus the tangential velocity component of the two fluids must be
+equal at the interface,
+\begin{equation}
+  \jmp{\vct u}\cdot\vct t = 0.
+\end{equation}
+It follows that
+\begin{align}
+  \label{eq:jmpu}
+  \jmp{\vct u} &= 0, \\
+  \label{eq:jmpJut}
+  \jmp{\grad \vct u}\cdot\vct t &= 0.
+\end{align}
+The latter is a direct consequence of the former.  Both fluids are
+incompressible, which gives the trivial identity $\jmp{\div\vct u} = 0$.  If we
+use the identity
+\begin{equation}
+  \div\vct u
+    = \vct n\cdot\grad\vct u\cdot\vct n + \vct t\cdot\grad\vct u\cdot\vct t
+  \label{eq:divuident}
+\end{equation}
+together with \eqref{eq:jmpJut} we get
+\begin{equation}
+  \vct n\cdot\jmp{\grad\vct u}\cdot\vct n = 0,
+  \label{eq:jmpngradun}
+\end{equation}
+which means that the normal component of the normal derivative of the velocity
+field is continuous across the interface.  Note that in \eqref{eq:divuident}
+and in similar expressions in the following, the nabla operator is only applied
+to $\vct u$, not the normal and tangential vectors that follow.
+

+  \end{tikzpicture}
+  \caption{A sketch of the control volume $\Omega_\epsilon$ that covers the
+    interface, $\Gamma$.}
+  \label{fig:domain_omega_epsilon}
+\end{figure}%
+Next, we consider the conservation of momentum.  We define a control volume
+\begin{equation}
+  \Omega_{\epsilon} = \set{\vct x \in \Omega}{\min_{\vct x_I \in \Gamma}|\vct
+    x - \vct x_I| \leq \epsilon},
+\end{equation}
+where $\epsilon > 0$, see \cref{fig:domain_omega_epsilon}.  We then integrate
+the Cauchy equation \eqref{eq:cauchy_equation} with the added singular
+surface-force term over the domain~$\Omega_\epsilon$,
+\begin{multline}
+  \intoepdx{\rho\td{\vct u}}
+    = \intoepdx{\div\tenstr} + \intoepdx{\rho\vct f} \\
+      + \intoepdx{ \int_{\Gamma}\sigma\kappa\vct n\delta(\vct x - \vct
+        x_I(\vct s))\dif\vct s}.
+\end{multline}
+Here $\tdi{\vct u} = \partial\vct u/\partial t + \vct u\cdot\grad\vct u$
+denotes the convective derivative.  Now we apply the Gauss theorem and change
+the order of integration in the last term to obtain
+\begin{equation}
+  \intoepdx{\rho\td{\vct u}} = \intdoepds{\tenstr\cdot\vct n}
+    + \intoepdx{\rho\vct f} + \int_\Gamma\sigma\kappa\vct n\dif\vct s.
+\end{equation}
+If we let $\epsilon$ go to zero, the left-hand side and the second term on the
+right-hand side vanish, and we get
+\begin{equation}
+  0 = \int_\Gamma\left( \jmp{\tenstr}\cdot\vct n + \sigma\kappa\vct
+    n \right)\dif s.
+  \label{eq:stressjumpint}
+\end{equation}
+Since the derivation above is also valid for any subset of $\Omega_\epsilon$
+containing a part of $\Gamma$, \eqref{eq:stressjumpint} must hold for any part
+of $\Gamma$.  Therefore
+\begin{equation}
+  0 = \jmp{\vct T}\cdot\vct n + \sigma\kappa\vct n.
+\end{equation}
+With $\vct T = -p\vct I + 2\mu\vct D$ we finally get the interface condition
+for the stresses,
+\begin{equation}
+  \label{eq:stress_jump}
+  \jmp{p}\vct n - \jmp{2\mu\tenD}\cdot\vct n = \sigma\kappa\vct n.
+\end{equation}
+The surface tension force is seen to introduce a discontinuity in the normal
+stresses across the interface.  The tangential stresses are continuous.
+
+\section{Interface conditions for the pressure and the viscous term}
+The previous section gave a brief derivation of the interface conditions for
+immiscible and incompressible two-phase flow without mass transfer.  In order
+to use these conditions for the discretization of the Navier-Stokes equations
+\eqref{eq:ns1} and \eqref{eq:ns2}, we need to rewrite them into a more suitable
+form.  In particular, we want to find explicit expressions for the jump in the
+pressure $\jmp p$ and the viscous term $\jmp{\mu\grad\vct u}$.  The following
+derivation is based on \cite{Hansen05} and \cite{Kang00}.
+
+First, a jump condition for the pressure is obtained by taking the inner
+product of \eqref{eq:stress_jump} with the normal vector $\vct n$,
+\begin{equation}
+  \jmp p = \vct n\cdot\jmp{2\mu\tenD}\cdot\vct n + \sigma\kappa
+      = 2\jmp{\mu}\vct n\cdot \grad\vct u \cdot\vct n
+        + \sigma\kappa,
+  \label{eq:jump_pressure}
+\end{equation}
+where \eqref{eq:jmpngradun} was used for the second equality.
+
+To find the jump in the viscous term, it is first decomposed into an interface
+normal coordinate system as
+\begin{equation}
+  \begin{split}
+    \jmp{\mu\grad\vct u} &=
+  \left(\vct n\cdot\jmp{\mu\grad\vct u}\cdot\vct n\right)\vct n\otimes\vct n +
+  \left(\vct t\cdot\jmp{\mu\grad\vct u}\cdot\vct t\right)\vct t\otimes\vct t
+        \\ &\quad+
+  \left(\vct n\cdot\jmp{\mu\grad\vct u}\cdot\vct t\right)\vct n\otimes\vct t +
+  \left(\vct t\cdot\jmp{\mu\grad\vct u}\cdot\vct n\right)\vct t\otimes\vct n,
+  \end{split}
+\end{equation}
+where $\otimes$ denotes the dyadic product.  We already showed that
+$\jmp{\grad\vct u}\cdot\vct t = 0$ and $\vct n\cdot\jmp{\grad\vct u}\cdot\vct
+n = 0$, cf.\ \eqref{eq:jmpJut} and \eqref{eq:jmpngradun}, which gives
+\begin{align}
+  \vct n\cdot\jmp{\mu\grad\vct u}\cdot\vct n &=
+    \jmp{\mu}\,\vct n\cdot\grad\vct u\cdot\vct n, \\
+  \vct t\cdot\jmp{\mu\grad\vct u}\cdot\vct t &=
+    \jmp{\mu}\,\vct t\cdot\grad\vct u\cdot\vct t, \\
+  \vct n\cdot\jmp{\mu\grad\vct u}\cdot\vct t &=
+    \jmp{\mu}\,\vct n\cdot\grad\vct u\cdot\vct t.
+\end{align}
+We then take the inner product of \eqref{eq:stress_jump} with $\vct t$, which
+gives
+\begin{equation}
+  \vct t\cdot\jmp{\mu\left(\grad\vct u + (\grad\vct u)^T \right)}\cdot\vct n
+  = \vct t\cdot\jmp{\mu\grad\vct u} \cdot\vct n
+    + \jmp{\mu}\vct n\cdot\grad\vct u \cdot\vct t
+  = 0,
+\end{equation}
+or
+\begin{equation}
+  \vct t\cdot\jmp{\mu\grad\vct u}\cdot\vct n =
+    - \jmp{\mu}\vct n\cdot\grad\vct u \cdot\vct t.
+\end{equation}
+The jump in the viscous term becomes
+\begin{multline}
+  \jmp{\mu\grad\vct u} = \jmp{\mu} \Big(
+       (\vct n\cdot\grad\vct u\cdot\vct n)\vct n\otimes\vct n
+     + (\vct n\cdot\grad\vct u\cdot\vct t)\vct n\otimes\vct t \\
+     - (\vct n\cdot\grad\vct u\cdot\vct t)\vct t\otimes\vct n
+     + (\vct t\cdot\grad\vct u\cdot\vct t)\vct t\otimes\vct t \Big).
+\end{multline}
+This can be simplified further by noting that
+\begin{equation}
+  (\grad\vct u\cdot t)\otimes\vct t
+  = (\vct n\cdot\grad\vct u\cdot\vct t)\vct n\otimes\vct t
+    + (\vct t\cdot\grad\vct u\cdot\vct t)\vct t\otimes\vct t.
+\end{equation}
+Thus we obtain the expression for the jump in the viscous term that has been
+used in the present work,
+\begin{multline}
+  \jmp{\mu\grad\vct u} = \jmp{\mu} \Big(
+       (\vct n\cdot\grad\vct u\cdot\vct n)\vct n\otimes\vct n
+     - (\vct n\cdot\grad\vct u\cdot\vct t)\vct t\otimes\vct n \\
+     + (\grad\vct u\cdot\vct t)\otimes\vct t \Big).
+  \label{eq:jumptens}
+\end{multline}
+
+\section{Summary}

+\chapter{Numerical methods}
+\label{chap:numerical-methods}
+This chapter describes the numerical methods that have been used in this thesis
+to solve the Navier-Stokes equations for two-phase flow.  First, a brief
+introduction to the level-set method is given, which is followed by an outline
+of the two projection methods that have been used to solve the Navier-Stokes
+equations.  The spatial and temporal discretization methods are then
+summarized, and at the end of the chapter the new methods to calculate the
+curvature and the normal vectors are presented.
+
+\section{The level-set method}
+\label{sec:level-set}
+In order to solve the Navier-Stokes equations for two-phase flow, we need to
+know the location of the interface.  The level-set method proposed by
+\citet{Osher88} allows us to capture the interface location as the zero level
+set of the level-set function $\varphi(\vct x,t)$.  The level-set function is
+typically defined as a signed-distance function,
+\begin{equation}
+  \varphi(\vct x,t) = \begin{cases}
+     d(\vct x,t) & \text{if } \vct x\in\Omega_2, \\
+    -d(\vct x,t) & \text{if } \vct x\in\Omega_1, \\
+  \end{cases}
+\end{equation}
+where $d(\vct x,t)$ is the shortest distance to the interface $\Gamma$,
+\begin{equation}
+  d(\vct x,t) = \min_{\vct x_I \in \Gamma} |\vct x - \vct x_I|.
+\end{equation}
+Thus the interface can be defined implicitly as
+\begin{equation}
+  \Gamma(t) = \set{\vct x\in\Omega}{\varphi(\vct x,t)=0},
+              \quad t\in \mathbb R^+.
+\end{equation}
+
+The position of the interface is updated by solving an advection equation for
+$\varphi$,
+\begin{equation}
+  \label{eq:ls_adeq}
+  \pdt{\varphi} + \vct{\hat u}\cdot\grad\varphi = 0,
+\end{equation}
+where $\vct{\hat u}$ is the velocity at the interface extended to the entire
+domain.  We extend the interface velocity through solving
+a velocity-extrapolation equation,
+\begin{equation}
+  \label{eq:ls_velextr}
+  \pd{\vct{\hat u}}{\tau} + S(\varphi)\vct n\cdot\grad\vct{\hat u} = 0,
+  \quad \vct{\hat u}_{\tau=0} = \vct u,
+\end{equation}
+to steady state, cf.\ \cite{Adalsteinsson99,Zhao96}.  Here $\tau$ is
+a pseudo-time and $S$ is a smeared sign function which is equal to zero at the
+interface,
+\begin{equation}
+  S(\varphi) = \frac{\varphi}{\sqrt{\varphi^2+2\Delta x^2}}.
+\end{equation}
+
+When we solve the level-set equation \eqref{eq:ls_adeq}, the non-uniform
+advection will distort the signed-distance property of the level-set function,
+and numerical dissipation error adds to this distortion.  The level-set
+function is therefore reinitialized regularly by solving
+\begin{equation}
+  \label{eq:ls_reinit}
+  \begin{split}
+    \pd{\varphi}{\tau} + S(\varphi_0)(|\grad\varphi|-1) &= 0, \\
+    \varphi(\vct x,0) &= \varphi_0(\vct x),
+  \end{split}
+\end{equation}
+to steady state as proposed by \citet{Sussman94}.  The level-set function just
+before initialization is used as the initial condition $\varphi_0$.
+
+The level-set equations \eqref{eq:ls_adeq}, \eqref{eq:ls_velextr}, and
+\eqref{eq:ls_reinit} are discretized in time and space as described in the
+following sections.  The method presented by \citet{Adalsteinsson95} is used to
+improve the computational speed.  The method is often called the narrow-band
+method, since the level-set function is only updated in a narrow band across
+the interface at each time step.
+
+One of the advantages of the level-set method is that normal vectors and
+curvatures can be readily calculated from the level-set function, that is,
+\begin{align}
+  \label{eq:norm}
+  \vct n &= \frac{\grad\varphi}{|\grad\varphi|}, \\
+  \label{eq:curv}
+  \kappa &= \div\left(\frac{\grad\varphi}{|\grad\varphi|}\right).
+\end{align}
+
+\section{Projection methods}
+\label{sec:projection-method}
+We have employed two different projection methods in this thesis to solve the
+incompressible Navier-Stokes equations for two-phase flow \eqref{eq:ns1} and
+\eqref{eq:ns2}.  Papers A, B, and C used the direct projection
+scheme~1~(DP1)~\cite{Hansen05}, and Paper D used the more standard Chorin
+projection method \cite{Chorin68}.
+
+The projection methods are a family of methods for the solution of the
+incompressible Navier-Stokes equations that are based on the Helmholtz-Hodge
+theorem.  This theorem states that an arbitrary vector field can be decomposed
+into a divergence-free part and a rotation-free part.  That is, any vector
+field $\vct a$ can be written as
+\begin{equation}
+  \vct a = \vct a' + \grad\psi,
+\end{equation}
+where $\vct a'$ is a vector with $\div\vct a' = 0$ and $\psi$ is a scalar
+potential.  The proof of this theorem can be found in for instance
+\cite[§3.44]{Aris89} or \cite{Chorin00}.
+
+\subsection{The direct projection scheme 1}
+The DP1 was developed by \citet{Hansen05} and is based on a direct application
+of the Helmholtz-Hodge theorem.  We assume that the velocity $\vct u$ is
+sufficiently smooth, and then rewrite \eqref{eq:navier-stokes-2} to get
+\begin{equation}
+  \label{eq:divFreeVel}
+  \pdt{\vct u} = \vct w - \frac{\grad p}{\rho},
+\end{equation}
+where
+\begin{equation}
+  \vct w = - (\vct u\cdot\grad)\vct u + \nu\grad^2\vct u + \vct f.
+  \label{eq:continuousRightHandVector}
+\end{equation}
+The divergence of \eqref{eq:divFreeVel} yields a Poisson equation for the
+pressure,
+\begin{equation}
+  \div\left(\frac{\grad p}{\rho}\right) = \div\vct w.
+  \label{eq:PoissonDP1}
+\end{equation}
+The DP1 scheme follows from a direct numerical discretization of the above
+equations.  First, $\vct w$ is calculated with
+\eqref{eq:continuousRightHandVector}.  Then the pressure is found by solving
+the Poisson equation \eqref{eq:PoissonDP1}.  Finally, an Euler step is used to
+solve \eqref{eq:divFreeVel}, that is,
+\begin{equation}
+  \vct u^{n+1} = \vct u^n + \Delta t\left(\vct w - \frac{\grad p}{\rho}\right).
+  \label{eq:dp1-update}
+\end{equation}
+
+\subsection{The Chorin projection method}
+The Chorin projection method was presented by \citet{Chorin68}, and is today
+one of the standard methods for solving the Navier-Stokes equations, e.g.\
+\cite{Walker12}.  The method is briefly presented in the following.
+
+Let $\Delta t$ be the time step, and consider the discretization of the
+momentum equation \eqref{eq:navier-stokes-2} with the forward Euler method,
+\begin{equation}
+  \frac{\vct u^{n+1} - \vct u^n}{\Delta t}
+  = -\vct u^n\cdot\grad\vct u^n
+    - \frac{\grad p^{n+1}}{\rho} + \frac\mu\rho\lapl\vct u^n + \vct f,
+  \label{eq:discmomeq}
+\end{equation}
+where $\vct u^n\equiv\vct u(\vct x,n\Delta t)$ and $p^n\equiv p(\vct x,n\Delta
+t)$ are assumed known at time level $n$.  Note that the pressure gradient is
+evaluated at time level $n+1$.  Next, to solve \eqref{eq:discmomeq} in two
+steps, we introduce the intermediate velocity field $\vct u^\star$,
+\begin{equation}
+  \frac{\vct u^{n+1} - \vct u^\star + \vct u^\star - \vct u^n}{\Delta t}
+  = -\vct u^n\cdot\grad\vct u^n
+    - \frac{\grad p^{n+1}}{\rho} + \frac\mu\rho\lapl\vct u^n + \vct f,
+\end{equation}
+which is chosen such that
+\begin{align}
+  \label{eq:ustar}
+  \frac{\vct u^\star - \vct u^n}{\Delta t}
+    &= -\vct u^n\cdot\grad\vct u^n + \frac\mu\rho\lapl\vct u^n + \vct f, \\
+  \label{eq:unext}
+  \frac{\vct u^{n+1} - \vct u^\star}{\Delta t} &= - \frac{\grad p^{n+1}}{\rho}.
+\end{align}
+From \eqref{eq:ustar} we get an explicit expression for $\vct u^\star$,
+\begin{equation}
+  \vct u^{\star} = \vct u^n
+    + \Delta t\left(-\vct u^n\cdot\grad\vct u^n
+        + \frac\mu\rho\,\lapl\vct u^n + \vct f\right).
+\end{equation}
+Next, the divergence of \eqref{eq:unext} and $\div\vct u^{n+1} = 0$ yields
+a Poisson equation for the pressure,
+\begin{equation}
+  \div\left(\frac{\grad p^{n+1}}{\rho}\right)
+    = \frac{\div\vct u^\star}{\Delta t}.
+  \label{eq:PoissonChorin}
+\end{equation}

+\section{Spatial discretization}
+\label{sec:x-discr}
+The governing equations \eqref{eq:ns1}, \eqref{eq:ns2}, \eqref{eq:ls_adeq},
+\eqref{eq:ls_velextr}, and \eqref{eq:ls_reinit} are discretized on a staggered
+grid~\cite{Harlow65}, where the scalar values are located at the cell centres
+and the vector values are located at the cell edges, see
+\cref{fig:staggered-grid}.  The domain boundary coincides with cell edges, and
+the fixed grid spacing is $\Delta x$ in the $x$ direction and $\Delta y$ in the
+$y$ direction.

+
+The $x$- and $y$-derivatives, divergence, and Laplacian operators are

+    &= \frac{p_{i+1,j} - p_{i,j}}{\Delta x}, \\

+\end{align}
+respectively.  Here $\vct u = (u,v)$ is a vector and $p$ is a scalar.  Note
+that the gradient of a scalar is a vector and has values located at the cell
+edges.  These definitions are consistent with the staggered grid, since the
+gradient returns a vector with components defined on the cell faces, while the
+divergence and the Laplacian returns a scalar defined at the cell centres.
+
+\subsection{Advective terms}
+The advective terms, $\vct u\cdot\grad\vct u$ in the momentum equation
+\eqref{eq:ns2} and $\vct{\hat u}\cdot\grad\varphi$ in the level-set equation
+\eqref{eq:ls_adeq}, and the normal derivative $\vct n\cdot\grad\vct{\hat u}$ in
+the velocity-extrapolation equation \eqref{eq:ls_velextr} are discretized with
+the weighted essentially non-oscillatory (WENO) scheme, cf.~\cite{Fedkiw99}
+and~\cite{Jiang96}.  The WENO scheme is a high-order upwind scheme that is
+fifth-order accurate in smooth regions.  In nonsmooth regions the accuracy is
+reduced to a minimum of third order.  The following is a brief outline of the
+WENO scheme.
+
+First, when we calculate the advective term for the velocity, the vector
+components are required on all cell edges.  That is, we must interpolate the
+$x$-component of the velocity to the location of the $y$-component of the
+velocity and vice versa.  To do this we use a linear interpolation,
+\begin{align}
+  u_{i,j+\frac 1 2} &= \frac 1 4\left(
+      u_{i-\frac 1 2,j  } + u_{i-\frac 1 2,j+1}
+    + u_{i+\frac 1 2,j+1} + u_{i+\frac 1 2,j  } \right), \\
+  v_{i+\frac 1 2,j} &= \frac 1 4\left(
+      v_{i,  j-\frac 1 2} + v_{i+1,j-\frac 1 2}
+    + v_{i+1,j+\frac 1 2} + v_{i  ,j+\frac 1 2} \right).
+\end{align}
+
+Similarly, when we calculate the advective term for the level-set function
+$\varphi$, we first interpolate the velocity to the scalar grid,
+\begin{align}
+  u_{i,j} &= \frac 1 2\left( u_{i+\frac 1 2,j} + u_{i-\frac 1 2,j} \right), \\
+  v_{i,j} &= \frac 1 2\left( v_{i,j+\frac 1 2} + v_{i,j-\frac 1 2} \right).
+\end{align}
+
+We now consider the WENO scheme for the advective operator in 1D at the point
+$x_{i+\frac 1 2}$.  The scheme extends naturally to higher dimensions.  First,
+if $u_{i+\frac 1 2} = 0$, then
+\begin{equation}
+  \left. u\pd u x \right|_{i+\frac 1 2} = 0.
+\end{equation}
+Otherwise we need to calculate a set of five differences that depend on the
+upwind direction.  The differences are denoted $\Delta v_k$ for $k=1,\dots,5$.
+If $u_{i+\frac 1 2}>0$, then we calculate
+\begin{equation}
+  \Delta v_k = \frac{u_{i+\frac{2k-5} 2} - u_{i+\frac{2k-7} 2}}{\Delta x}.
+\end{equation}
+Otherwise if $u_{i+\frac 1 2}<0$, we calculate
+\begin{equation}
+  \Delta v_k = \frac{u_{i-\frac{2k-9} 2} - u_{i-\frac{2k-7} 2}}{\Delta x}.
+\end{equation}
+Next we calculate expressions for the smoothness of three substencils,
+\begin{align}
+  S_1 &= \frac{13}{12}(\Delta v_1 - 2\Delta v_2 + \Delta v_3)^2
+    + \frac 1 4 (\Delta v_1 - 4\Delta v_2 + 3\Delta v_3)^2, \\
+  S_2 &= \frac{13}{12}(\Delta v_2 - 2\Delta v_3 + \Delta v_4)^2
+    + \frac 1 4 (\Delta v_2 - \Delta v_4)^2, \\
+  S_3 &= \frac{13}{12}(\Delta v_3 - 2\Delta v_4 + \Delta v_5)^2
+    + \frac 1 4 (3\Delta v_3 - 4\Delta v_4 + \Delta v_5)^2,
+\end{align}
+where a small $S$ indicates a smooth substencil.  These smoothness factors are
+then used to compute weights for the substencils,
+\begin{equation}
+  w_k = \frac{b_k}{b_1+b_2+b_3},
+\end{equation}
+for $k = 1,2,3$, where
+\begin{equation}
+  b_1 = \frac 1 {10}\frac 1 {(\epsilon+S_1)^2},\quad
+  b_2 = \frac 6 {10}\frac 1 {(\epsilon+S_2)^2},\quad
+  b_3 = \frac 3 {10}\frac 1 {(\epsilon+S_3)^2}.
+\end{equation}
+Here $\epsilon$ is a regularization parameter that is used to avoid division by
+zero.  We have used $\epsilon = 10^{-6}$ in this work.  Finally, the WENO
+scheme for the gradient becomes
+\begin{multline}
+  \left. \pd u x \right|_{i+\frac 1 2} \simeq
+      w_1\left(\frac 1 3\Delta v_1 - \frac 7 6\Delta v_2
+        + \frac{11} 6 \Delta v_3\right) \\
+    + w_2\left(-\frac 1 6\Delta v_2 + \frac 5 6\Delta v_3
+        + \frac 1 3 \Delta v_4\right) \\
+    + w_3\left(\frac1 3\Delta v_3 + \frac 5 6\Delta v_4
+        - \frac 1 6 \Delta v_5\right).
+\end{multline}
+
+\subsection{The viscous term}
+The viscous term $\mu\lapl\vct u$ in the Navier-Stokes equations is discretized
+by standard second-order central differences using the ghost-fluid method
+(GFM)~\cite{Fedkiw99,Kang00,Liu00}.  This method includes the jump in the
+viscous term at the interface \eqref{eq:jumptens} in the discretization stencil
+in a sharp manner.
+
+In the following we present the GFM scheme in the one-dimensional case.  The
+extension to higher dimensions is straightforward.  In order to simplify the
+notation, we omit the half indices and let $k\equiv i+\frac 1 2$.  Further, we
+consider a general case where
+\begin{equation}
+  \jmp u = a_\Gamma, \qquad \jmp{\mu\pd u x} = b_\Gamma.
+\end{equation}
+For the viscous term, $a_\Gamma = 0$, cf.\ \eqref{eq:jmpu}, and $b_\Gamma$ is
+given by the jump tensor~\eqref{eq:jumptens}.  The jump tensor is calculated at
+the cell centres near the interface with the second-order central-difference
+scheme.  It is then interpolated linearly to the cell edges, from where it is
+again interpolated linearly to the interface when needed.
+
+If the interface does not cross the stencil, then the GFM scheme reduces to the
+standard second-order central-difference stencil.  Else there are four
+stencils, depending on the location of the interface.  One such interface
+configuration is sketched in \cref{fig:gfm-scheme-example}.  In all the
+stencils, $\theta$ is defined as the relative distance from the interface to
+the node on the left, for instance
+\begin{equation}
+  \theta = \frac{|\varphi_{k}|}{|\varphi_{k}| + |\varphi_{k+1}|},
+\end{equation}
+where $\varphi_k$ and $\varphi_{k+1}$ are the level-set function values
+linearly interpolated to the vector grid.  The four stencils are given below,
+where $h\equiv\Delta x$.
+\begin{enumerate}
+  \item Phase 1 is to the left and interface lies between $k$ and $k+1$:
+    \begin{align}
+      \begin{split}
+        \left.\pd{} x\left(\mu\pd u x\right)\right|_{x_k}
+          &= \frac{\hat\mu\left(u_{k+1} - u_{k}\right)
+                 - \mu_1\left(u_{k} - u_{k-1}\right)}{h^2} \\
+          &\qquad
+             - \frac{\hat\mu a_\Gamma}{h^2}
+             - \frac{\hat\mu b_\Gamma (1-\theta)}{\mu_2 h},
+      \end{split} \\
+       \hat\mu &= \frac{\mu_1\mu_2}{\theta\mu_2 + (1-\theta)\mu_1}.
+    \end{align}
+  \item Phase 1 is to the left and interface lies between $k-1$ and $k$:

+          &= \frac{\mu_2\left(u_{k+1} - u_{k}\right)
+                - \hat\mu\left(u_{k} - u_{k-1}\right)}{h^2} \\
+          &\qquad
+            + \frac{\hat\mu a_\Gamma}{h^2}
+            - \frac{\hat\mu b_\Gamma \theta}{\mu_1 h},
+      \end{split} \\
+      \hat\mu &= \frac{\mu_1\mu_2}{\theta\mu_2 + (1-\theta)\mu_1}.
+    \end{align}
+  \item Phase 2 is to the left and interface lies between $k$ and $k+1$:
+    \begin{align}
+      \begin{split}
+        \left.\pd{} x\left(\mu\pd u x\right)\right|_{x_k}
+          &= \frac{\hat\mu\left(u_{k+1} - u_{k}\right)
+                - \mu_2\left(u_{k} - u_{k-1}\right)}{h^2} \\
+          &\qquad
+            + \frac{\hat\mu a_\Gamma}{h^2}
+            + \frac{\hat\mu b_\Gamma (1-\theta)}{\mu_1 h},
+      \end{split} \\
+      \hat\mu &= \frac{\mu_1\mu_2}{\theta\mu_1 + (1-\theta)\mu_2}.
+    \end{align}
+  \item Phase 2 is to the left and interface lies between $k-1$ and $k$:

+          &= \frac{\mu_1\left(u_{k+1} - u_{k}\right)
+                - \hat\mu\left(u_{k} - u_{k-1}\right)}{h^2} \\

+      \end{split} \\
+      \hat\mu &= \frac{\mu_1\mu_2}{\theta\mu_1 + (1-\theta)\mu_2}.

+\subsection{Pressure Poisson equation}
+\label{sec:pressure-poisson}
+The Laplace operator in the Poisson equations \eqref{eq:PoissonDP1} and
+\eqref{eq:PoissonChorin} is also discretized by standard second-order central
+differences using the GFM~\cite{Kang00,Liu00}.  The GFM was discussed in the
+previous section, where stencils were given for the viscous term in the
+one-dimensional case.  For the pressure, the stencils are the same except we
+use $p$ instead of $u$, and $1/\rho$ and $1/\hat\rho$ instead of $\mu$ and
+$\hat\mu$.  To find the jump in the pressure at the interface, $\jmp
+p = a_\Gamma$, the jump condition \eqref{eq:jump_pressure} is calculated at the
+cell centres and then interpolated to the interface.  In addition, we use that
+$b_\Gamma = 0$, which is justified by \citet[Section~3.7]{Kang00}.
+
+The resulting linear system for the pressure is solved with a solver from the
+Portable, Extensible Toolkit for Scientific Computation (PETSc)~\cite{PETSc}.
+PETSc makes available a large selection of solvers.  In most cases, we used the
+direct solver based on LU factorisation or the conjugate gradient method with
+incomplete Cholesky factorisation.  In some cases, we used the GMRES solver
+with a preconditioner, either incomplete LU factorisation or an algebraic
+multigrid method.  See \cite{PETSc} for more details and a list of available
+methods, and see for example~\cite{Iserles09} or~\cite{Saad03} for an
+introduction to linear solvers.
+
+Finally, the gradient of the pressure, used in \eqref{eq:divFreeVel} and
+\eqref{eq:velcorrection}, is also calculated with the GFM.  In one dimension,
+the stencil is
+\begin{align}
+  \left. \frac 1 \rho \pd p x\right|_{i+\frac 1 2}
+           &= \frac 1 {\hat\rho} \frac{(p_{i+1} - a_\Gamma) - p_i} h, \\
+  \hat\rho &= \theta\rho_1 + (1-\theta)\rho_2,
+\end{align}
+if $\phi_i\leq 0$ and $\phi_{i+1}>0$, or else
+\begin{align}
+  \left. \frac 1 \rho \pd p x\right|_{i+\frac 1 2}
+           &= \frac 1 {\hat\rho} \frac{(p_{i+1} + a_\Gamma) - p_i} h, \\
+  \hat\rho &= \theta\rho_2 + (1-\theta)\rho_1,
+\end{align}
+where
+\begin{equation}
+  \theta = \frac{|\varphi_{i}|}{|\varphi_{i}| + |\varphi_{i+1}|}.
+\end{equation}
+
+\section{Temporal discretization}
+\label{sec:t-discr}
+The temporal discretization is done with the explicit strong
+stability-preserving Runge-Kutta (SSP-RK) schemes, see
+\cite{Ketcheson05,Shu88}.  The idea behind the SSP-RK schemes is to preserve
+the stability of a low-order method when it is extended to higher order.  It is
+argued in \cite{Gottlieb01} that if one extends the forward Euler method, which
+is total variation diminishing (TVD) for a suitable discretization of a scalar
+conservation law, to a non-SSP higher-order method, then overshoots may occur
+at discontinuities.
+
+An SSP-RK method can be written as a convex sum of explicit Euler steps with
+time step $\Delta t$,
+\begin{equation}
+  \mathcal E\left(x^n\right) = x^n + \Delta t \mathcal F(x^n,t^n).
+\end{equation}
+where $\mathcal F$ is the residual of the PDE to be solved.  In this thesis we
+have used two methods:  The third-order three-stage SSP-RK method~\cite{Shu88},
+\begin{equation}
+  \begin{split}
+    x^{(1)} &= \mathcal E\left(x^n\right), \\
+    x^{(2)} &= \frac 3 4 x^n + \frac 1 4\mathcal E\left(x^{(1)}\right), \\
+    x^{n+1} &= \frac 1 3 x^n + \frac 2 3\mathcal E\left(x^{(2)}\right),
+  \end{split}
+  \label{eq:ssprk33}
+\end{equation}
+and the third-order four-stage SSP-RK method~\cite{Kraaijevanger91},
+\begin{equation}
+  \begin{split}
+    x^{(1)} &= \frac 1 2 x^n + \frac 1 2\mathcal E\left(x^n\right), \\
+    x^{(2)} &= \frac 1 2 x^{(1)} + \frac 1 2\mathcal E\left(x^{(1)}\right), \\
+    x^{(3)} &= \frac 2 3 x^n + \frac 1 6 x^{(2)}
+               + \frac 1 6\mathcal E\left(x^{(2)}\right), \\
+    x^{n+1} &= \frac 1 2 x^{(3)} + \frac 1 2\mathcal E\left(x^{(3)}\right).
+  \end{split}
+  \label{eq:ssprk34}
+\end{equation}
+
+The semi-discretized velocity-extrapolation equation \eqref{eq:ls_velextr} and
+level-set reinitialization equation \eqref{eq:ls_reinit} can be written as
+systems of ordinary differential equations (ODEs) of the form
+\begin{equation}
+  \od{\vct \psi} \tau = \vct F(\vct\psi,\tau),
+\end{equation}
+where $\vct\psi$ is a vector containing the discrete variables and $\vct F$
+contains the spatially discretized terms.  The explicit Euler step becomes
+\begin{equation}
+  \mathcal E(\vct\psi^n) = \vct\psi^n + \Delta\tau \vct F(\vct\psi^n,\tau^n).
+\end{equation}
+In this thesis, these equations are solved with the third-order four-stage
+SSP-RK method \eqref{eq:ssprk34}.  The four-stage method is used because it is
+more accurate than the three-stage method.  We wanted to make sure that the
+error is mainly dominated by the spatial discretization.
+
+The semi-discretized Navier-Stokes equations \eqref{eq:navier-stokes-1} and
+\eqref{eq:navier-stokes-2} are solved together with the level-set advection
+equation \eqref{eq:ls_adeq} with the third-order three-stage SSP-RK method
+\eqref{eq:ssprk33}.  Here an explicit Euler step $\mathcal E(\vct
+u^n,\varphi^n)$ consists of the following steps:
+\begin{enumerate}
+  \item Calculate the curvature and the normal vectors from $\varphi^n$ with
+    one of the methods described in \cref{sec:curvature}.
+  \item Calculate the intermediate velocity field, either $\vct w$
+    \eqref{eq:continuousRightHandVector} or $\vct u^\star$ \eqref{eq:ustar}.
+  \item Solve the Poisson equation \eqref{eq:PoissonDP1} or
+    \eqref{eq:PoissonChorin} for the pressure as described in
+    \cref{sec:pressure-poisson}.
+  \item Correct the velocity field with either \eqref{eq:dp1-update} or
+    \eqref{eq:velcorrection}.
+  \item Advect the level-set function $\varphi^n$ with \eqref{eq:ls_adeq}.
+\end{enumerate}
+
+\section{Time step restriction}
+\label{sec:deltaT}
+We employ the Courant-Friedrich-Lewy~(CFL) condition to allow adaptive time
+stepping and to enforce stability.  The CFL condition that is used in this
+thesis is
+\begin{equation}
+  \Delta t = \frac{C}{\frac{C_c + C_v} 2
+             + \sqrt{(C_c + C_v)^2 + 4C_g^2 + 4C_s^2}},
+\end{equation}
+where the CFL restriction $C<1$, and $C_c$, $C_v$, $C_s$, and $C_g$ represent
+the contributions from the convective term, the viscous stresses, the surface
+tension, and the gravity, respectively,
+\begin{align}
+  C_c &=  \frac{\max_{i,j}|u_{i,j}|}{\Delta x}
+        + \frac{\max_{i,j}|v_{i,j}|}{\Delta y}, \\
+  C_v &= 2\max\left(\frac{\mu_1}{\rho_1},\frac{\mu_2}{\rho_2}\right)
+         \left(\frac{1}{\Delta x^2} + \frac{1}{\Delta y^2}\right), \\
+  C_s &= \sqrt{\frac{\sigma\max_{i,j}|\kappa_{i,j}|}
+                    {\max(\rho_1,\rho_2)\min(\Delta x^2,\Delta y^2)}}, \\
+  C_g &= \sqrt{\frac{|g_x|}{\Delta x} + \frac{|g_y|}{\Delta y}}.
+\end{align}
+This CFL condition is discussed in more detail by~\citet{Lervag08}, and it is
+based on the condition by \citet{Kang00}.
+
+\section{Axisymmetry}
+For axisymmetric flow, the governing equations \eqref{eq:ns1} and
+\eqref{eq:ns2} become
+\begin{equation}
+  \frac 1 r \pd{} r\left(r u\right) + \pd v z = 0,
+\end{equation}
+\begin{multline}
+  \rho\left(\pdt u + u\pd u r + v\pd u z\right) = -\pd p r \\
+    + \mu\left(\frac 1 r \pd{} r\left(r \pd u r\right)
+          + \pdd u z - \frac u {r^2}\right) + \rho f_r + {f_s}_r,
+\end{multline}
+and
+\begin{multline}

+\section{Discretization of the curvature and the normal vector}
+\label{sec:curvature}
+As stated in \cref{sec:level-set}, the normal vector \eqref{eq:norm} and the
+curvature \eqref{eq:curv} can be calculated from the level-set function as
+\begin{align*}
+  \vct n &= \frac{\grad\varphi}{|\grad\varphi|}, \\
+  \kappa &= \div\left(\frac{\grad\varphi}{|\grad\varphi|}\right).
+\end{align*}
+They are typically discretized with the standard second-order
+central-difference scheme, cf.\ \cite{Kang00,Sethian03,Xu06}.  The normal
+vector is calculated at the cell edges, and the curvature is calculated at the
+grid nodes.  The curvature is then interpolated to the interface where needed
+with linear interpolation, for instance with
+\begin{equation}
+  \kappa_\Gamma = \frac{|\varphi_{i,j}|\kappa_{i+1,j}
+  + |\varphi_{i+1,k}|\kappa_{i,j}}{|\varphi_{i,j}| + |\varphi_{i+1,j}|}.
+  \label{eq:curvature-gamma}
+\end{equation}
+
+If the level-set method is used to capture non-trivial geometries, then it will
+contain kink regions, that is, areas where the gradient of the level-set
+function is discontinuous.  \Cref{fig:level-set-function} shows a simple
+example of such a kink region for a level-set function in a one-dimensional
+domain that captures two interfaces, one on each side of $x_i$.  The kink at
+$x_i$ may lead to large errors both for the curvature and the normal vector if
+one is not careful.  Errors in the curvature lead to errors in the surface
+tension force and in the pressure, which in turn lead to errors in the
+interface evolution and in the two-phase flow.  Errors in the normal vector
+affect both the calculation of the viscous jump condition and the advection of
+the interface.  If the level-set method is used to study for example
+coalescence and breakup of drops, these errors may severely affect the
+simulations.

+\end{figure}
+
+This problem was to our knowledge first described by \citet{Smereka03}, who
+increase the numerical smoothing in the curvature discretization to lessen the
+effect.  Several non-smearing approaches have subsequently been developed.
+\citet{Macklin05} used the level-set method to study tumor growth, and they
+present a one-sided direction-difference scheme for the discretization of the
+normal vector and the curvature.  Later, \citet{Macklin06} presented an
+improved geometry-aware curvature discretization, where the curvature is
+calculated based on a local least-squares parametrisation of the interface.
+
+A different approach to avoid the kinks was presented by \citet{Salac08}.  They
+used a level-set extraction technique, where an extraction algorithm was used
+to reconstruct separate level-set functions for each distinct \emph{body}.  The
+term \emph{body} is used here to denote a subset of a given phase or fluid.
+For example, in the case of two drops of water colliding in air, the water
+drops would make two distinct bodies.  One can also avoid the extraction
+algorithm altogether by use of multiple marker functions for different bodies,
+see for instance \cite{Coyajee09,Kwakkel12}.  Note, however, that the latter
+approach means that the different bodies will not coalesce unless explicit
+action is made, cf.~\cite{Kwakkel13}.  Also, both of the approaches mentioned
+here fails to handle the problem of kinks from a single body.  That is, there
+may still be kink areas due to deformed bodies, for instance bodies with thin
+filaments or tails, or bodies shaped like horse shoes.
+
+In the following, we first present the direction-difference
+scheme~\cite{Macklin05}.  We then describe the curve-fitting discretization
+method and the local level-set extraction method.
+
+\subsection{Direction-difference scheme}
+\label{sec:dds}
+The direction-difference scheme (DDS) was introduced by \citet{Macklin05}.  It
+uses a quality function to ensure that the difference stencils never cross any
+kink regions.  The DDS is used in Papers A--C to calculate the normal vectors.
+However, in Paper C it is shown that the DDS does not always yield an accurate
+approximation of the normal vector.
+
+The basic strategy is to use a combination of central differences and one-sided
+differences based on the values of a quality function,
+\begin{equation}
+  Q(\vct x) = \left| 1 - |\grad\varphi(\vct x)|\right|.
+  \label{eq:quality}
+\end{equation}
+The quality function is approximated with central differences, and is used to
+detect the areas where the level-set function differs from the signed-distance
+function.  In the following, let $Q_{i,j} \equiv Q(\vct x_{i,j})$ and define
+a parameter $\eta>0$.  This threshold parameter is tuned such that the quality
+function will detect all the kinks.
+
+The quality function is used to define a direction function,
+\begin{equation}
+  \vct D(\vct x_{i,j}) = (D_x(\vct x_{i,j}), D_y(\vct x_{i,j})),
+\end{equation}
+where
+\begin{equation}
+  D_x(\vct x_{i,j}) = \begin{cases}
+    -1 & \text{if $Q_{i-1,j}<\eta$ and $Q_{i+1,j}\geq\eta$,} \\
+     1 & \text{if $Q_{i-1,j}\geq\eta$ and $Q_{i+1,j}<\eta$,} \\
+     0 & \text{if $Q_{i-1,j}<\eta$ and $Q_{i,j}<\eta$ and $Q_{i+1,j}<\eta$,} \\
+     0 & \text{if $Q_{i-1,j}\geq\eta$ and $Q_{i,j}\geq\eta$ and
+         $Q_{i+1,j}\geq\eta$,} \\
+     4 & \text{otherwise.}
+  \end{cases}
+  \label{eq:dirfunc}
+\end{equation}
+$D_y(\vct x_{i,j})$ is defined in a similar manner.  If $D_x(\vct x_{i,j})
++ D_y(\vct x_{i,j}) > 2$, then $\vct D(\vct x_{i,j})$ is chosen as the vector
+normal to $\grad\varphi(\vct x_{i,j})$.  It is normalized, and the sign is
+chosen such that it points in the direction of the best quality.  See
+\cite{Macklin05} for more details.
+
+The DDS is then defined as
+\begin{equation}
+  \partial_x f_{i,j} = \begin{cases}
+    \frac{f_{i,j} - f_{i-1,j}}{\Delta x}    & \text{if $D_x(x_i,y_j) = -1$,} \\
+    \frac{f_{i+1,j} - f_{i,j}}{\Delta x}    & \text{if $D_x(x_i,y_j) =  1$,} \\
+    \frac{f_{i+1,j} - f_{i-1,j}}{2\Delta x} & \text{if $D_x(x_i,y_j) =  0$,}
+  \end{cases}
+  \label{eq:Ddifference}
+\end{equation}
+and similarly for $\partial_y f_{i,j}$, where $f_{i,j}$ is a piecewise smooth
+function.  The DDS is equivalent to using central differences in smooth areas
+and one-sided differences in areas close to the kinks.
+
+\subsection{Curve-fitting discretization method}
+\label{sec:curvature-curve-fitting}
+The curve-fitting discretization method (CFDM) was first presented
+in~\cite{Lervag11} and is based on the method by \citet{Macklin06}.  The main
+idea is to identify kink regions with the quality function \eqref{eq:quality},
+and to use a curve parametrisation of the closest interface to calculate the
+curvature in regions where the quality function is larger than the threshold
+parameter, $\eta$.
+
+The CFDM applied to the curvature or the normal vector at the grid point $\vct
+x_{i,j}$ can be summarized as follows.  See also \cref{fig:cfdm}, which shows
+an example of the CFDM used at $\vct x_{i,j}$.
+\begin{enumerate}
+  \item If the quality of the level-set function in the neighbourhood of $\vct
+    x_{i,j}$ is good, that is
+    \[
+      Q(\vct{x}_{n,m}) \le \eta \; \forall (n,m) \in [i-1,i+1]\times[j-1,j+1],
+    \]
+    then we use a standard discretization.  Otherwise continue to the next
+    step.
+  \item Locate the closest interface, $\Gamma$.
+  \item Find a set of points on the located interface, $\vct x_1, \dots, \vct
+    x_n \in \Gamma$.
+  \item Create a parametrisation $\vct \gamma(s)$ of the points $\vct x_1,
+    \dots, \vct x_n$.
+  \item Use the parametrisation $\vct \gamma(s)$ to calculate a local level-set
+    function.
+  \item Use a standard discretization of the local level-set function to
+    calculate the curvature or the normal vector.
+\end{enumerate}

+\subsection{Local level-set extraction method}
+\label{sec:lolex}
+The local level-set extraction (LOLEX) method is based on the method presented
+by \citet{Salac08}, here called the SLM.  It was found that the latter method
+was insufficient, because it did not treat all the kink problems.  The LOLEX
+method is therefore a further development of the SLM, in that it handles the
+kink regions in a more general manner.
+
+The LOLEX method applied to the curvature or the normal vector at a grid point
+$\vct x_{i,j}$ is summarized by the following algorithm.  The algorithm is
+presented with 2D notation for clarity, and extends easily to 3D.  See also
+\cref{fig:lolex}, which gives a simple example of the procedure.
+\begin{enumerate}
+  \item If the quality in the neighbourhood of $\vct x_{i,j}$ is good, that is
+    \[
+      Q(\vct{x}_{n,m}) \le \eta \; \forall (n,m) \in [i-1,i+1]\times[j-1,j+1],
+    \]
+    then we use a standard discretization.  Otherwise continue to the next
+    step.
+  \item Copy a small, local square centred around $\vct x_{i,j}$ from the
+    level-set function $\varphi$ into a local array $\varphi_\text{loc}$.
+  \item Identify and enumerate all the \emph{bodies} in the local array
+    $\varphi_\text{loc}$.  A \emph{body} is here defined as a set of
+    neighbouring points where $\varphi_\text{loc}<0$, see \cref{fig:lolex}.
+    There will be $n\geq 0$ bodies in any given $\varphi_\text{loc}$ array.
+  \item If no body is identified, that is, if $n=0$, then use a standard
+    discretization with the global level-set function $\varphi$.  Otherwise
+    continue to the next step.
+  \item For each body $n$, extract the relevant parts of $\varphi_\text{loc}$
+    into an array $\varphi_\text{loc}^n$.  If necessary, extrapolate values to
+    ghost cells.
+  \item For each body, $n$, reinitialize $\varphi_\text{loc}^n$.
+  \item At this step, all the bodies in the local grid have their own
+    local level-set functions that have been reinitialized to proper
+    signed-distance functions.  Due to the separation of the bodies, there
+    are no longer any kinks.
+  \item Use the standard discretization of the curvature and the normal
+    vector at the local level-set function that represents the body that is
+    closest to $\vct x_{i,j}$.

+\section{Summary}
+In this chapter we have described the numerical methods that have been used to
+solve the Navier-Stokes equations for two-phase flow \eqref{eq:ns1}
+and~\eqref{eq:ns2}.
+
+We first gave a brief introduction to the level-set method, which is used to
+capture the interface.  We then presented the spatial and temporal
+discretization methods, including a brief overview of the projection methods
+that were used to decouple the pressure from the Navier-Stokes equations.  In
+the final section, we presented the new methods for calculating the curvature
+and normal vector.  These are the curve-fitting discretization scheme (CFDM)
+and the local level-set extraction (LOLEX) method.

+\chapter{The diffuse-domain approach}
+\label{chap:diffuse-domain}
+In the previous chapters, we have considered the modelling of two-phase flows,
+and in particular methods for calculating the curvature and normal vector with
+the level-set method in a reliable manner.  In this chapter, we consider
+a different problem of a more general nature:  How to solve partial
+differential equations (PDEs) in complex domains.  In particular, we consider
+an extension of a diffuse-domain method (DDM) by a high-order correction term
+that gives increased accuracy with respect to interface-width refinements.
+
+We begin with a short introduction to the diffuse-domain approach.  We then

+
+\section{Introduction}
+There exist several methods for solving PDEs in complex domains.  Most of them
+have in common that they require tools or methods that are not frequently
+available in standard finite-element or finite-difference software packages.
+Examples of such methods include the immersed-interface method
+\cite{LeVeque94}, the matched interface and boundary method \cite{Zhou06}, the
+extended and composite finite-element method \cite{Dolbow09}, embedded boundary
+methods \cite{Johansen98}, cut-cell methods \cite{Ji06}, and ghost-fluid
+methods \cite{Fedkiw99}.  A different approach, known as the fictitious domain
+method~\cite{Glowinski94,Glowinski96} or the domain imbedding
+method~\cite{Buzbee71}, either augments the original system with equations for
+Lagrange multipliers to enforce the boundary conditions, or use the penalty
+method to enforce the boundary conditions weakly.  For a more complete list of
+references, see Paper~E.
+
+The DDM is an alternative method for solving PDEs in complex domains.  The main
+idea is to use an implicit representation of the boundary, where the sharp
+boundary is replaced by a diffuse layer.  The PDEs are then reformulated on
+a larger, regular domain, and the boundary conditions are incorporated via
+source terms in the diffuse layer.  When the thickness of the diffuse layer is
+reduced, these source terms tend towards singular source terms.  The resulting
+PDEs can then be solved with the use of standard tools and methods.
+
+The diffuse-domain approach was first introduced by \citet{Kockelkoren03} to
+study diffusion inside a cell with homogeneous Neumann boundary conditions at
+the cell boundary.  It was later used by \citet{Li09} to develop a DDM for
+solving PDEs in complex evolving domains with Dirichlet, Neumann and Robin
+boundary conditions, which is hereafter called the DDM1.  The DDM1 has been
+used by \citet{Teigen09-b}, who modelled bulk-surface coupling of material
+quantities on a deformable interface.  It was also used by \citet{Aland10} to
+simulate incompressible two-phase flows in complex domains in 2D and 3D, and by
+\citet{Teigen11} to study two-phase flows with soluble surfactants.
+
+An analysis of the error behaviour of the diffuse-domain approach was done by
+\citet{Franz12} for a diffuse-domain approximation of an elliptic problem with
+Dirichlet boundary conditions.  They considered the infinity norm of the
+difference of the approximated solution and the exact solution, and their
+analysis shows that the approximation quality is of order one in the interface
+width.
+
+In Paper~E, we present the DDM2, which is an extension of the DDM1 by
+a high-order correction term.  The DDM2 is derived for elliptic problems with
+Neumann and Robin boundary conditions, and it is shown to be asymptotically
+second-order accurate in the interface width.  However, the analysis in Paper~E
+is somewhat lacking in that it assumes that the DDM1 is only first-order
+accurate.  In the following sections, we extend the analysis of Paper~E and
+show that the DDM1 is also second-order accurate.  The analysis is shown for
+the steady reaction-diffusion equation with Neumann boundary conditions, but
+the same technique also applies for the corresponding Robin problem.
+
+\section{The DDM for a Neumann problem}
+Consider the steady reaction-diffusion equation with Neumann boundary
+conditions,
+\begin{equation}
+  \begin{alignedat}{2}
+    \lapl u - u  &= f        & \txin D, \\
+    \ndot\grad u &= g \qquad & \txon \partial D,
+  \end{alignedat}
+  \label{eq:ddan}
+\end{equation}
+where $f$ and $g$ are given.  Let $\chi_D$ be the characteristic function of
+$D$,
+\begin{equation}
+  \chi_D = \begin{cases}
+    1 & \text{if $x\in D$,} \\
+    0 & \text{if $x\notin D$.}
+  \end{cases}
+\end{equation}
+The main idea with the diffuse-domain approach is to extend the original
+equation \eqref{eq:ddan} into a larger and regular domain $\Omega\supset D$, as
+depicted in \cref{fig:ddadomain}.  The extension can be written as
+\begin{equation}
+  \div(\chi_D\grad u) - \chi_D u + \text{BC} = \chi_D f,
+  \label{eq:ddm}
+\end{equation}
+where BC is a singular source term that represents the physical boundary
+condition on $\partial\Omega$.

+  \end{tikzpicture}
+  \caption{A regular domain $\Omega$ that contains a complex domain $D$.}
+  \label{fig:ddadomain}
+\end{figure}
+
+The characteristic function is typically approximated by the phase-field
+function,
+\begin{equation}
+  \chi_D \simeq \phi(\vct x,t) = \frac{1}{2} \left( 1
+  - \tanh \left( \frac{3r(\vct x,t)}{\epsilon} \right) \right),
+  \label{eq:characteristic}
+\end{equation}
+where $\epsilon$ is the interface width and $r(\vct x,t)$ is the
+signed-distance function with respect to the boundary $\partial D$, which is
+taken to be negative inside $D$.
+
+The main difficulty with the diffuse-domain approach is the derivation of
+approximations for the boundary condition term BC.  \citet{Li09} give four
+approximations that are shown to converge asymptotically with first order in
+$\epsilon$ to the original equation when $\epsilon$ is decreased.  In the
+following we consider the approximation
+\begin{equation}
+  \text{BC} \simeq |\grad\phi| g.
+  \label{eq:bc1}
+\end{equation}
+If we combine the above approximations \eqref{eq:characteristic} and
+\eqref{eq:bc1}, we get a DDM1 equation for \eqref{eq:ddan},
+\begin{equation}
+  \div\left(\phi\grad u\right) - \phi u +  |\grad\phi| g = \phi f.
+  \label{eq:ddm1}
+\end{equation}
+
+\section{The method of matched asymptotic expansions}
+The following is a brief introduction to the method of matched asymptotic
+expansions, which is used to show that a given diffuse-domain approximation
+converges to the original problem when the interface width is decreased.  More
+details can be found in Paper~E and in \cite{Pego88}.
+
+Let $u$ be some diffuse-domain variable.  The asymptotic convergence of a given
+diffuse-domain approximation can be shown through expansions of the
+diffuse-domain variables in powers of the interface thickness $\epsilon$ in
+regions close to and far from the interface.  For example, the expansions of
+$u$ are
+\begin{align}
+  u(\vct x)        &= \sum_{k=0}^\infty \epsilon^k      u^{(k)}(\vct x), \\
+  \hat u(z,\vct s) &= \sum_{k=0}^\infty \epsilon^k \hat u^{(k)}(z,\vct s),
+\end{align}
+where $u(\vct x)$ and $\hat u(\vct s,z)$ denote the outer and inner expansions,
+respectively.  Here $z$ is a stretched variable,
+\begin{equation}
+  z = \frac{r(\vct x)}{\epsilon},
+\end{equation}
+where $r$ is the signed distance from the point $\vct x$ to $\partial D$ and is
+taken to be negative inside $D$.  Further, $z$ and $\vct s$ form a local
+coordinate system such that
+\begin{equation}
+  \vct x(\vct s,z) = \vct X(\vct s) + \epsilon z\vct n(\vct s),
+\end{equation}
+where $\vct X(\vct s)$ is a parametrisation of the interface, $\vct n(\vct s)$
+is the interface normal vector, and $z$ is a stretched variable.
+
+When the inner and outer expansions are found, they are matched in a region
+where both solutions are valid and where $\epsilon z = \bigo 1$, see
+\cref{fig:regions}.  The outer solution is then evaluated in the inner
+coordinates, which leads to a set of matching conditions that must hold when
+$\epsilon\to 0$.  If we consider $\epsilon$ to be fixed and let $z \to
+\pm\infty$, we get the following asymptotic matching conditions:
+\begin{equation}
+  \label{eq:match1}
+  \zlimpm \hat u^{(0)}(z,\vct s) = u^{(0)}(\vct s),
+\end{equation}
+and as $z \to \pm\infty$,
+\begin{align}
+  \label{eq:match2}
+  \hat u^{(1)}(z,\vct s) &= u^{(1)}(\vct s)
+    + z\ndot\grad u^{(0)}(\vct s) + \smallo 1, \\
+  \begin{split}
+    \hat u^{(2)}(z,\vct s) &= u^{(2)}(\vct s)
+      + z\ndot\grad u^{(1)}(\vct s) \\
+      &\quad + \frac{z^2}{2} (\ndot\grad)\grad u^{(0)}(\vct s)\cdot\vct n
+      + \smallo 1.
+    \label{eq:match3}
+  \end{split}

+\end{figure}
+
+We remark that the inner expansion is used to obtain the boundary condition on
+$\partial D$, and that the outer solution is used to obtain the sharp-interface
+equation inside the physical domain $D$.
+
+To show that a given DDM approximation converges with second order, one must
+show that the order-one term of the outer solution of the DDM equation is zero
+in $D$.  As an example, we consider the outer solution of the DDM1 equation
+\eqref{eq:ddm1}, which is
+\begin{equation}
+  \begin{split}
+    \lapl u^{(0)} - u^{(0)} &= f, \\
+    \lapl u^{(1)} - u^{(1)} &= 0, \\
+    \lapl u^{(k)} - u^{(k)} &= 0,\qquad k = 2,3,\dots.
+  \end{split}
+  \label{eq:ddm_outer}
+\end{equation}
+For the solution to be asymptotically second order, that is $u = u^{(0)}
++ \bigo{\epsilon^2}$, we must have that $u^{(0)}$ satisfies the original
+problem \eqref{eq:ddan} and that $u^{(1)}=0$.  Thus the inner expansion must
+yield a boundary condition for $u^{(1)}$ to enforce $u^{(1)}=0$.
+
+\section{Asymptotic analysis of the DDM1 and the DDM2}
+\label{sec:DDM2}
+In Paper~E we present the DDM2, which extends the DDM1 \eqref{eq:ddm1} with
+a high-order correction term,
+\begin{equation}
+  \div\left(\phi\grad u\right) - \phi u +  |\grad\phi| g
+    + r|\grad\phi|\left(f - \kappa  g - \lapls u + u\right) = \phi f.
+  \label{eq:ddm2}
+\end{equation}
+Here $r|\grad\phi|\left(f - \kappa  g - \lapls u + u\right)$ is the
+correction term, $\kappa$ is the curvature of the boundary $\partial D$, and
+$\lapls u$ is the surface Laplacian of $u$, which can be defined as
+\begin{equation}
+  \lapls u \equiv
+  \left( I - \vct n\otimes\vct n \right)
+        \div \left( I - \vct n\otimes\vct n \right)\grad u,
+\end{equation}
+where $I$ is the identity matrix and $\vct n$ is the normal vector.  The
+curvature can be calculated from the phase-field function
+\eqref{eq:characteristic} as
+\begin{equation}
+  \kappa = -\div\frac{\grad\phi}{|\grad\phi|}.
+\end{equation}
+
+In the following, we use the method of matched asymptotic expansions to show
+that the DDM1 \eqref{eq:ddm1} and the DDM2 \eqref{eq:ddm2} are both
+second-order approximations of \eqref{eq:ddan} in $\epsilon$.  First, it is
+easy to see that the outer expansions of both approximations are given by
+\eqref{eq:ddm_outer}.
+
+Next, we consider the inner expansion of the DDM2 \eqref{eq:ddm2}, which is
+\begin{multline}
+  \frac{1}{\epsilon^2}\left(\phi\hat u_z\right)_z
+  + \frac \kappa \epsilon \phi\hat u_z
+  + \phi\lapls \hat u
+  - \phi\hat u \\
+  - \frac 1 \epsilon \phi_z g
+  - z\phi_z\left(\hat u + \hat f - \kappa g - \lapls\hat u\right)
+  = \phi \hat f.
+  \label{eq:ddm_inner}
+\end{multline}
+We expand $\hat u(z,\vct s)$ in powers of $\epsilon$ and collect the lowest
+order terms,
+\begin{equation}
+  \left(\phi\hat u_z^{(0)}\right)_z = 0.
+\end{equation}
+If we integrate over all $z$, we get that $\hat u_z^{(0)} = 0$.  The next order
+terms of~\eqref{eq:ddm_inner} then give
+\begin{equation}
+  \left(\phi\hat u_z^{(1)}\right)_z = \phi_z g,
+\end{equation}
+and again we integrate, which gives that
+\begin{equation}
+  \phi\hat u_z^{(1)} = \phi g + C
+  \label{eq:uz1}
+\end{equation}
+where the constant $C$ must be zero, since $\lim_{z\to\infty}\phi(z) = 0$.  Now
+consider the limit $z\to-\infty$ and use the matching condition
+\eqref{eq:match2} to get
+\begin{equation}
+  \ndot\grad u^{(0)} = g.
+\end{equation}
+Thus $u^{(0)}$ satisfies the original problem at least to first order in
+$\epsilon$.  This shows that both DDM1 and DDM2 are first-order approximations
+of the sharp-interface problem.
+
+To obtain the result for the next order, we need to apply the derivative of
+the matching condition \eqref{eq:match3},
+\begin{equation}
+  \hat u_z^{(2)} = \ndot\grad u^{(1)}
+      + z (\ndot\grad)\grad u^{(0)}\cdot\vct n.
+  \label{eq:match3_z}
+\end{equation}
+Further, we use that $u^{(0)}$ satisfies
+\begin{equation}
+  \lapl u^{(0)} - u^{(0)} = f^{(0)},
+\end{equation}
+and that the Laplacian may be decomposed as
+\begin{equation}
+  \lapl u = (\ndot\grad)\grad u\cdot\vct n + \kappa\ndot\grad u + \lapls u,
+\end{equation}
+to get
+\begin{equation}
+  (\ndot\grad)\grad u^{(0)}\cdot\vct n
+    = u^{(0)} + f^{(0)} - \kappa g - \lapls u^{(0)}.
+  \label{eq:ngradun}
+\end{equation}
+Now insert \eqref{eq:ngradun} into \eqref{eq:match3_z} and use the matching
+condition \eqref{eq:match1} to obtain a modified matching condition,
+\begin{equation}
+  \hat u_z^{(2)} - z\left(\hat u^{(0)} + \hat f^{(0)}
+        - \kappa g - \lapls \hat u^{(0)}\right)
+  = \ndot\grad u^{(1)}.
+  \label{eq:match3_z2}
+\end{equation}
+
+We are now ready to consider the zeroth order terms,
+\begin{multline}
+  \label{eq:o1}
+  \left(\phi\hat u^{(2)}_z\right)_z
+  + \phi\kappa\hat u_z^{(1)}
+  + \phi\lapls \hat u^{(0)}
+  - \phi\hat u^{(0)} \\
+  - z\phi_z\left(\hat u^{(0)}
+      + \hat f^{(0)} - \kappa g - \lapls\hat u^{(0)}\right)
+  = \phi \hat f^{(0)}.
+\end{multline}
+The modified matching condition \eqref{eq:match3_z2} motivates that we subtract
+and add the term
+\[
+  \bigg(z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\bigg)_z
+\]
+to \eqref{eq:o1}, which gives
+\begin{multline}
+  \bigg(\phi\hat u_z^{(2)}
+    - z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\bigg)_z \\
+  + \bigg(z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\bigg)_z \\
+  + \phi\kappa\hat u_z^{(1)}
+  + \phi\lapls \hat u^{(0)}
+  - \phi\hat u^{(0)} \\
+  - z\phi_z\left(\hat u^{(0)}
+      + \hat f^{(0)} - \kappa g - \lapls\hat u^{(0)}\right)
+  = \phi \hat f^{(0)}.
+\end{multline}
+We expand the terms and use \eqref{eq:uz1},
+\begin{multline}
+  \bigg(\phi\hat u_z^{(2)}
+    - z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\bigg)_z \\
+  + \cancel{\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)} \\
+  + z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)_z \\
+  + \cancel{\phi\kappa g
+  + \phi\lapls \hat u^{(0)}
+  - \phi\hat u^{(0)}}
+  = \cancel{\phi \hat f^{(0)}},
+  \label{eq:o2}
+\end{multline}
+or
+\begin{multline}
+  \bigg(\phi\hat u_z^{(2)}
+    - z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\bigg)_z \\
+  + z\phi\left(\cancel{\hat u_z^{(0)}} + \hat f_z^{(0)}
+      - \cancel{(\kappa g)_z}
+      - \cancel{\lapls \hat u_z^{(0)}}\right) = 0.
+\end{multline}
+If we assume that $\hat f_z^{(0)}$, we get
+\begin{equation}
+  \bigg(\phi\hat u_z^{(2)}
+    - z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\bigg)_z = 0.
+  \label{eq:o3}
+\end{equation}
+Finally, we integrate the left-hand side and take the limit,
+\begin{align}
+  \nonumber
+  \eint{\bigg(\phi\hat u_z^{(2)}
+    &- z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+     - \lapls \hat u^{(0)}\right)\bigg)_z} \\
+  \nonumber
+  &= \ejmp{\phi\hat u_z^{(2)}
+    - z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)} \\
+  \nonumber
+  &= -\zlimm{\left(\hat u_z^{(2)}
+    - z\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\right)} \\
+  &= -\ndot\grad u^{(1)},
+\end{align}
+thus
+\begin{equation}
+  \ndot\grad u^{(1)} = 0.
+  \label{eq:ngradu1}
+\end{equation}
+Combined with \eqref{eq:ddm_outer}, this shows that $u^{(1)}=0$, and so DDM2
+converges asymptotically with second order to the original problem.
+
+The analysis above also holds for DDM1, except instead of \eqref{eq:o3} we get

+  \bigg(\phi\hat u_z^{(2)}
+    - z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g

+  = - z\phi_z \left(\hat u^{(0)} + \hat
+        f^{(0)} - \kappa g - \lapls \hat u^{(0)}\right)
+  = - z\phi_z D,
+  \label{eq:o4}
+\end{multline}
+where $D$ is independent of $z$.  Now we use that
+\begin{equation}
+  \phi_z = -(3 \sech^2 3z)/2,
+\end{equation}
+which follows from the definition of the phase-field function
+\eqref{eq:characteristic}.  We integrate the right-hand side, which gives
+\begin{equation}
+  D\eint{z\phi_z} = -D\frac 3 2\eint{z\sech^2 3z} = 0.
+\end{equation}
+Thus DDM1 is also second order in $\epsilon$.
+
+The difference between the DDM1 and the DDM2 is therefore that the correction
+term with the DDM2 directly cancels the term on the right-hand side in
+\eqref{eq:o4}.  This should give an increase of accuracy, but the convergence
+order remains the same.
+
+The analysis for the corresponding Robin problem is essentially the same as the
+above.  In Paper~E, the DDM1 and DDM2 are compared for several elliptic
+problems with both Neumann and Robin boundary conditions.  The results of
+Paper~E show that the correction term in the DDM2 leads to an increase of
+accuracy and that both DDM1 and DDM2 converge with second-order accuracy.
+
+\section{Summary}
+In this chapter, we have given a brief introduction to the diffuse-domain
+method (DDM).  We considered a steady reaction-diffusion equation with Neumann
+boundary conditions \eqref{eq:ddan} and two DDM approximations:  DDM1
+\eqref{eq:ddm1} and DDM2 \eqref{eq:ddm2}.  The DDM2 is an extension of DDM1 by
+a high-order correction term, and was first derived in Paper~E.
+
+Next, we gave an outline of the method of matched asymptotic expansions, and we
+used it to show that both the DDM1 and the DDM2 converged asymptotically with
+second order in the diffuse-interface width to the original equation
+\eqref{eq:ddan}.  The analysis shows that the correction term in the DDM2 leads
+to a cancellation in the asymptotic expansions.  By doing the integration, we
+see that this cancellation is not necessary for obtaining the second order
+convergence.

+  level-set method}
+Karl Yngve Lervåg.  Published in \emph{MekIT'11 - 6th National Conference on
+  Computational Mechanics, Trondheim}, 2011.  ISBN: 978-82-519-2798-7.
+
+In this paper I address a problem with the calculation of the interface
+curvature with the level-set method, cf.\ \cref{sec:curvature}.  The curvature
+can be calculated from the level-set function, $\phi$, as
+\begin{equation}
+  \kappa = \div\vct n = \div\frac{\grad\phi}{|\grad\phi|}.
+\end{equation}
+It is typically discretized by standard methods such as the second-order
+central-difference scheme (CD-2), and interpolated to the interface where
+needed \cite{Osher88,Kang00,Osher03}.  However, the level-set function as
+a signed-distance function will tend to have kinks where its gradient is
+discontinuous.  The standard methods may lead to large errors in the curvature
+close to these regions, which in turn may lead to errors in the surface tension
+force.
+
+The main contribution of this paper is a new curve-fitting discretization
+method (CFDM) for the curvature (see \cref{sec:curvature-curve-fitting}).  The
+method is based on the approach developed by \citet{Macklin06}.  It differs in
+that it uses a cubic Hermite spline parametrisation of the interface, and that
+the curvature values are calculated on the grid and then interpolated to the
+interface as opposed to using a localised grid centred at the interface as in
+\cite{Macklin06}.

+
+The CFDM is tested and compared with the CD-2 for two test cases, and it is
+shown to yield better results in both cases.  \Cref{fig:A1} shows one of these
+results, where the calculated curvature values are compared.  In the example,
+a cylindrical drop impacts on a liquid film.  The figure shows that the CD-2
+leads to large errors in the curvature calculations in the kink regions, that
+is, the red and dark blue regions in \cref{fig:A1a} near the liquid film.
+These errors are not present with the new method, cf.\ \cref{fig:A1b}.

+\section[Paper B]{Paper B:  Curvature calculations for the level-set method}
+Karl Yngve Lervåg and Åsmund Ervik.  Published in \emph{ENUMATH 2011}
+proceedings volume, Springer, 2013.  ISBN: 978-3642331336.
+
+This paper is a continuation of Paper A.  The main contribution in this paper
+is a comparison of different methods for calculating the curvature in a robust
+manner with the level-set method in the kink regions.  In particular, the
+CFDM\footnote{The method is called LM in the paper.  Here CFDM is used, in
+  order to be consistent with the rest of the thesis.} that was presented in
+Paper A is compared with Macklin and Lowengrub's method (MLM)~\cite{Macklin06}.
+In addition, the method is compared with the second-order central-difference
+scheme (CD-2) and the more recent method presented by \citet{Salac08}, here
+called Salac and Lu's method (SLM).
+
+The main result in the paper is shown in \cref{fig:B1}, which shows
+a comparison of the methods for a case where two drops collide in a 2D shear
+flow.  In particular, it shows snapshots of the evolution of the interfaces and
+the curvature at times $t=\SI{2.30}{s}$, $t=\SI{2.75}{s}$, and
+$t=\SI{3.10}{s}$.  The results show that all of the improved methods, that is
+MLM, CFDM, and SLM, handle the kink region in a more reliable manner than CD-2.
+The reason that the result with MLM differs from those with CFDM and SLM might
+be that it uses a localised grid centred at the interface to calculate the
+curvature, which means that it does not need to use interpolation of the
+curvature from the grid to the interface.  Note that the difference is mainly
+that the MLM results in slightly earlier coalescence in the given case.

+\section[Paper C]{Paper C:  Calculation of the interface curvature and normal
+  vector with the level-set method}
+Karl Yngve Lervåg, Bernhard Müller, and Svend Tollak Munkejord.  Published in
+Computers and Fluids, volume 84 (2013), 218--230.
+
+Paper A presented the curve-fitting discretization method (CFDM) for the
+calculation of the curvature with the level-set method.  The method was
+designed to be robust in the calculation of the curvature in kink regions, that
+is regions where the gradient of the level-set function is not smooth.  This
+paper presents the details of the CFDM and applies it to the calculation of
+both the curvature and the normal vector.
+
+In the paper we compare the CFDM with the second-order central-difference
+scheme (CD-2) for several test cases.  In the first case, we consider the
+curvature calculations for a nontrivial geometry that includes some kink
+regions.  This is a static test case with no flow, and the results show that
+the CD-2 leads to large errors for the curvature calculations in areas close to
+kink regions and that these errors are not present with the CFDM.
+
+In the following two cases, we consider the collision of two drops in a 2D
+shear flow and in an axisymmetric flow.  These cases show that the errors in
+the curvature calculations in the kink regions with the CD-2 lead to errors in
+the pressure that prevents coalescence.  These errors are prevented with the
+CFDM.  The curvature and the evolution of the interfaces for the axisymmetric
+case are shown in \cref{fig:C1,fig:C2}.  As in the earlier results of Papers
+A and B, the figures show that the errors in the curvature calculation with
+CD-2 prevent coalescence, in this case leading to a slower coalescence process.

+\section[Paper D]{Paper D:  A robust method for calculating interface curvature
+  and normal vectors using an extracted local level set}
+Åsmund Ervik, Karl Yngve Lervåg, and Svend Tollak Munkejord.  Submitted to
+Journal of Computational Physics, 2013.
+
+In this paper we present an alternative method for the calculation of the
+curvature and the normal vector of an interface with the level-set method in
+kink regions, hereafter called the local level-set extraction (LOLEX) method.
+The method is based on a method presented by \citet{Salac08} (SLM), who handle
+the kink region by extracting different bodies of a domain into separate
+level-set functions.  This procedure removes most of the kink regions, but it
+does not handle kink regions that are due to complex interfaces of single
+bodies.  Our method extends the SLM by making it local.  That is, we only
+consider the local area around the point for which we are calculating the
+curvature or the normal vector.  This leads to a method that is more generally
+applicable, as shown in \cref{fig:D1}.  The figure shows a comparison between
+the LOLEX method, the SLM, and the standard central differences (CD-2).  CD-2
+leads to curvature spikes at the kink regions, as explained in
+\cref{sec:curvature}.  The SLM gives a better result for the kink regions
+around the rightmost disc.  However, since the other two discs are connected to
+each other and to the film, they are considered to be the same body and are
+extracted into the same level-set function.  Several kink regions are therefore
+not removed.  Since the LOLEX method only considers the local area, as
+explained in \cref{sec:lolex}, it is able to handle all the kink regions in
+a robust manner.

+
+The LOLEX method has proven to be a good alternative to the CFDM presented in
+Paper A.  Its main advantages are that it does not rely on complex algorithms
+as used in the CFDM or by \citet{Macklin06}, and that the method easily extends
+to 3D as demonstrated in the paper in Section~4.4.
+
+In the previous papers A--C, we used the DP1 projection method by
+\citet{Hansen05}.  In this paper we instead used the more standard Chorin
+projection method.  These methods differ in that the DP1 assumes
+\begin{equation}
+  \div\left(\pdt{\vct u}\right) = 0.
+\end{equation}
+When compared with the Chorin method, this assumption becomes equivalent to
+assuming that $\div\vct u^{n} = 0$ in \eqref{eq:PoissonChorin}.  That is, the
+DP1 assumes that the initial velocity field is divergence free.  We have found
+that the DP1 works well in most cases, but that it is less robust than the
+Chorin method.  In particular, the Chorin method is not equally affected by
+errors in the curvature calculations in kink regions.  In other words, the
+difference between using a standard discretization and an improved
+discretization of the curvature is smaller with the Chorin method than with the
+DP1.
+
+The LOLEX method is used for several test cases and compared with CD-2.  The
+results indicate that even though we use the Chorin projection method, the
+LOLEX method outperforms CD-2 in all cases.  Further, the results agree well
+with experiments, except for time instants, as shown in \cref{fig:D2}.  The
+exact reason why the time instants do not match is not known, but one reason
+may be that the initial condition of the numerical simulation did not match the
+corresponding state of the experiment.

+
+When we study the drop-film collision processes, an important consequence of
+the error in the curvature calculation is a loss of kinetic energy.  This can
+be seen in \cref{fig:D3}, which compares the LOLEX method with CD-2 at two
+different stages of the collision process.  The figure also compares two
+different frequencies of reinitialization of the level-set function:  Every
+7 time steps ((a) and (c)) and every single time step ((b) and (d)).  The
+figure shows that the error in the curvature calculation with CD-2 leads to
+a shorter neck, as seen in \cref{fig:D3}, (c) and (d).  The error is larger for
+the higher frequency of reinitialization.  The results indicate that CD-2 leads
+to a loss of kinetic energy during the collision process when compared with the
+LOLEX method.  The LOLEX method is not significantly affected by the amount of
+reinitialization, and the kink region does not affect the curvature
+calculation, cf.\ \cref{sec:lolex}.  Thus the pressure field is more sensible,
+as seen in \cref{fig:D3} (a) and (b).  Finally, we remark that some authors
+have noted \cite{Blanchette06} that the height of the neck and the dynamics of
+the capillary waves are important factors for the partial coalescence
+mechanism, which implies that the correct calculation of the curvature is
+important to capture the correct physical behavior.

+\section[Paper E]{Paper E:  Towards a second-order diffuse-domain approach for
+  solving PDEs in complex geometries}
+Karl Yngve Lervåg and John Lowengrub.  Submitted to Communications in Math.
+Sciences, 2013.
+
+\citet{Li09} developed a diffuse-domain method for solving partial-differential
+equations (PDEs) inside complex, dynamic geometries with Dirichlet, Neumann,
+and Robin boundary conditions.  This method is in the following referred to as
+DDM1.  They use the diffuse-domain approach~\cite{Kockelkoren03}, where the
+geometry is represented implicitly and the sharp boundary is replaced by
+a diffuse layer with a fixed interface width.  The original governing equations
+are then reformulated on a larger, regular domain and the boundary conditions
+are incorporated via singular source terms.  The method of matched asymptotic
+expansions is used to show that the reformulated problem converges
+asymptotically to the original problem.
+
+In the present paper, we use the method of matched asymptotic expansions to
+extend the DDM1 with include a high-order correction term in the diffuse
+formulation, cf.\ \cref{sec:DDM2}.  The extension is derived for elliptic
+problems with Neumann and Robin boundary conditions, where the correction term
+is shown to yield an asymptotically second-order accurate approximation of the
+original problem.  The new method is referred to as the DDM2.
+
+The DDM1 and DDM2 are compared for a selection of test problems.  The resulting
+equations were discretized by standard second-order central-difference schemes
+on uniform grids, and solved by a multigrid method.  A red-black Gauss-Seidel
+type iterative method was used as a smoother, see \cite{Wise07}.
+
+In addition to the comparison of DDM1 and DDM2, we compared two different
+approximations of the boundary conditions.  These correspond to different
+diffuse-interface surface delta functions, and for the Neumann boundary
+conditions they are
+\begin{equation}
+  \text{BC1} = |\grad\phi| g,
+\end{equation}
+and
+\begin{equation}
+  \text{BC2} = \epsilon|\grad\phi|^2 g.
+\end{equation}
+The approximations are similar for the Robin boundary condition, although here
+it was found that only BC1 resulted in a valid asymptotically second-order
+accurate DDM2.
+
+Our results show that the global accuracy and convergence of DDM2 is better
+than DDM1, however both methods perform well and the global convergence rate is
+around two for each.  The error was measured as the L$_2$ norm of the
+difference between an analytic solution and the solution $u_\epsilon$ for
+a given interface width, $\epsilon$.
+
+\Cref{fig:E1,fig:E2} show two of the results, the first one with the Neumann
+boundary conditions and the second with the Robin boundary condition.  The
+results indicate that DDM2 performs slightly better than DDM1.  They also show
+that the approximation BC1 gives more accurate results than BC2.  In
+particular, we found that with BC2 we needed much finer grids to obtain
+convergence for a given $\epsilon$.  For the smallest values of $\epsilon$ we
+were not able to refine the grids enough to obtain valid results.

+\chapter{Conclusions and outlook}
+\label{chap:conclusions}
+This thesis has considered two different problems:  The discretization of
+interface curvature and normal vectors with the level-set method and
+a diffuse-domain approach for solving partial-differential equations (PDEs) in
+complex domains.  In the following, some general concluding remarks and
+recommendations for further work are given.
+
+\section*{Conclusions}
+The first part of the thesis considered the modelling of incompressible
+two-phase flow.  The main motivation was to study two-phase flow phenomena that
+are relevant for compact heat exchangers, such as drop-drop and drop-film
+collisions.  In particular, the thesis addressed a challenge with the
+calculation of interface curvature and normal vectors with the level-set
+method.  Two methods were presented to handle the discretization in the kink
+regions: A curve-fitting discretization method (CFDM) and a local level-set
+extraction (LOLEX) method.  Both methods were shown to be robust in the kink
+regions, where the standard central-difference scheme (CD-2) fails.  Of these
+methods, the LOLEX method is the preferred method, because it relies on a less
+complicated algorithm that easily extends to 3D.
+
+CD-2 and the LOLEX method were used for simulations of drop-film collisions
+that were compared with experiments.  The results showed that CD-2 leads to
+errors in the curvature that cause unphysical pressure spikes during the
+coalescence.  The errors are shown to lead to a dissipation of kinetic energy
+during the collision and to a slower coalescence process.  The LOLEX method was
+shown to prevent these unphysical pressure spikes, and to produce to more
+accurate results.
+
+The second part of the thesis considered the diffuse-domain approach for
+solving PDEs in complex domains.  The main contribution, presented in Paper~E,
+was the derivation of an asymptotically second-order diffuse-domain method
+(DDM2) for solving elliptic problems in complex geometries with Neumann and
+Robin boundary conditions.  The new method is an extension by a high-order
+correction term of the method presented in \cite{Li09}, here called DDM1.  The
+DDM1 and DDM2 were compared, and the results indicated that the DDM2 was
+slightly better than the DDM1.
+
+The thesis has expanded on the results of Paper~E with a new asymptotic
+analysis that shows that DDM1 is in fact also asymptotically second order.
+This analysis helps to explain why the performance of DDM2 presented in Paper~E
+is only slightly better than that of DDM1.  As such, the new analysis leads to
+a better understanding of the DDM1 and the DDM2.
+
+\section*{Outlook}
+The following gives an outline of some possibilities for future work.
+\begin{itemize}
+  \item A natural continuation of this work is to perform more in-depth
+    comparisons of simulations with experiments for the drop-film collision
+    phenomenon that was started in Paper~D.  In addition, it would be
+    interesting to study other two-phase flow phenomena that are relevant for
+    heat-exchanger processes, for instance drop-drop collisions or flow across
+    tube bundles.  The latter requires the treatment of more complex boundaries,
+    which can be handled either with the diffuse-domain method or other methods
+    from the literature.
+  \item Paper~C gave a short comparison of the standard discretization method
+    (CD-2), the direction-difference scheme (DDS), and the curve-fitting
+    discretization scheme (CFDM) applied to the calculation of the normal
+    vectors.  The results showed that the CD-2 leads to inaccurate results in
+    the kink regions.  The DDS gives robust and accurate results in most cases,
+    but an example is given where only the CFDM yields an accurate result.
+    However, the impact of inaccurate calculations of the normal vector should
+    be investigated in more detail.  The normal vector is used both for the
+    solution of the level-set equations \eqref{eq:ls_adeq},
+    \eqref{eq:ls_velextr}, and \eqref{eq:ls_reinit}, and for the calculation of
+    the interface jumps \eqref{eq:jump_pressure} and \eqref{eq:jumptens}, so
+    one can expect that large errors in the calculation of the normal vector
+    may lead to large errors in the numerical solution.  This warrants
+    a further study.
+  \item Mass and heat transfer are obviously an important part of the
+    heat-exchanger processes.  The models that have been used in this thesis
+    should therefore be expanded with additional models for heat transfer and
+    mass transfer to enable the simulation of more relevant phenomena.
+  \item The DDM2 was only derived for problems with Robin and Neumann boundary
+    conditions.  If possible, it should be extended to also work with Dirichlet
+    boundary conditions.
+  \item As explained in Paper~E, we found that we were unable to solve the
+    discrete system of equations when the surface Laplacian part of the
+    correction term for the DDM2 was included.  A further investigation of this
+    problem should be done, and stable numerical methods to solve the full DDM2
+    equations should be developed.
+  \item The diffuse-domain approach is a promising method for solving problems
+    in complex and confined geometries with standard tools and methods.
+    \citet{Aland10} provide a diffuse-domain formulation of the Navier-Stokes
+    Cahn-Hilliard equations for incompressible two-phase flow and use it to
+    compute two-phase flow in both complex and confined geometries.  However,
+    they do not provide an asymptotic analysis of the reformulated equations to
+    show that the system converges.  Such an analysis would be interesting, in
+    particular to verify that the equations do converge to the original problem
+    when the interface width is decreased.
+  \item Finally, it would be interesting to develop a second-order
+    diffuse-domain formulation for the incompressible Navier-Stokes equations.
+    A starting point would be to use the results and techniques from this
+    thesis and Paper~E.

+\noindent Standard \LaTeX{} practice is to write inline math by enclosing it between \verb|\(...\)|:
+
+\begin{quote}
+  In physics, the mass-energy equivalence is stated
+  by the equation \(E=mc^2\), discovered in 1905 by Albert Einstein.
+\end{quote}
+
+\noindent Instead if writing (enclosing) inline math between \verb|\(...\)| you can use \texttt{\$...\$} to achieve the same result:
+
+\begin{quote}
+  In physics, the mass-energy equivalence is stated
+  by the equation $E=mc^2$, discovered in 1905 by Albert Einstein.
+\end{quote}
+
+\noindent Or, you can use \verb|\begin{math}...\end{math}|:
+
+\begin{quote}
+  In physics, the mass-energy equivalence is stated
+  by the equation \begin{math}E=mc^2\end{math}, discovered in 1905 by Albert Einstein.
+\end{quote}
+
+This is a simple math expression \(\sqrt{x^2+1}\) inside text. 
+And this is also the same: 
+\begin{math}
+\sqrt{x^2+1}
+\end{math}
+but by using another command.
+
+This is a simple math expression without numbering
+\[\sqrt{x^2+1}\] 
+separated from text.
+
+This is also the same:
+\begin{displaymath}
+\sqrt{x^2+1}
+\end{displaymath}
+
+\ldots and this:
+\begin{equation*}
+\sqrt{x^2+1}
+\end{equation*}

+Therefore, in that case the observed dynamics cannot be truly Markovian. We can

+eq.~\ref{eq:fpe}; however the local coefficients are then effectively averages
+over the co-evolving unobserved distribution. For example, $\vec v(\vec
+x,t)=\int p(\vec x^u|\vec x,t)v(\vec x,\vec x^u,t)dx^u$. This has some

+distribution over $x^u$ when sampled at label $\vec x$ some time later; another
+population started around $\vec x_1$ carries a different history when it, too,
+visits $\vec x$ later. Therefore, for instance the effective drift $\vec v(\vec
+x)$ will be different in the two cases. We conclude that, if unobserved degrees

+
+This thesis considers in the first part the mathematical modelling of
+incompressible two-phase flow, in particular the calculation of interface
+curvatures and normal vectors with the level-set method.  The main contribution
+is the development of two new numerical methods that enable a more robust
+calculation of the curvature and normal vectors in areas where the gradient
+of the level-set method is discontinuous.
+
+Incompressible two-phase flow is in this thesis modelled by the Navier-Stokes
+equations with a singular source term at the interface between the phases.  The
+singular source term leads to a set of interface jump conditions.  These jump
+conditions are used in the ghost-fluid method to solve two-phase flow in
+a sharp manner.  The interface position is captured and evolved in time with
+the level-set method.  The Navier-Stokes equations for two-phase flow are
+solved with projection methods and discretized by finite differences in space
+and Runge-Kutta methods in time.  The advective terms in the governing
+equations are discretized by a weighted essentially non-oscillatory scheme.
+
+In the second part, the thesis considers the more general problem of solving
+partial-differential equations (PDEs) in complex geometries.  An extension of
+a diffuse-domain method is presented, where the accuracy is improved by adding
+a correction term.  The extension is derived for elliptic problems with Neumann
+and Robin boundary conditions.  One of the advantages of the diffuse-domain
+methods is that they allow the use of standard tools and methods because they
+are based on solving PDEs reformulated in larger and regular domains.

+\chapter{Introduction}
+This thesis considers the mathematical modelling and numerical computation of
+two-phase flows.  It focuses on developing more robust numerical methods to
+calculate the curvature and the normal vector of the interface between the two
+phases.  In addition it considers a diffuse-domain method for solving partial
+differential equations in complex geometries, and it derives an asymptotically
+second-order method for elliptic problems.
+
+\section{Background and motivation}
+Two-phase flows are particular examples of multiphase flows of gas and liquid
+with an interface that separates the two phases.  In the pedantic sense,
+two-phase flow is flow of a single fluid that occurs as two different phases,
+for example steam and water.  However, it is common to be more general, and in
+this thesis we use the term two-phase flow also for immiscible mixtures of
+different fluids, such as water and oil.
+
+Two-phase flows are crucial to a large amount of processes, both in nature and
+in industry.  Examples range from weather phenomena, such as rain drops falling
+through air, to industrial processes, for instance the separation of water from
+oil.  In general, multiphase flow phenomena influence any process where liquids
+and gases are involved.  In the oil and gas industry, most processes are
+two-phase or multiphase flow processes.  Needless to say, the understanding of
+these phenomena is fundamental in the development of new or improved processes.
+
+Consider the international trade of liquefied natural gas (LNG), which is
+a particular branch of the oil and gas industry that has undergone an
+exceptional growth in the last decades.  There is a strong focus both in Norway
+and internationally on producing LNG on large floaters
+(FLNG)\footnote{FLNG facilities do not yet exist, although a facility is under
+  development by Royal Dutch Shell~\cite{Prelude1}.  The construction of this
+  facility was started in 2012, and the first drilling is stated to commence in
+  2013~\cite{Prelude2}.}.  There are a number of both environmental and
+economic advantages of such FLNG facilities.  In particular, FLNG facilities
+would remove the need of long pipelines from the gas fields to the shore, there
+would be no requirement for compression units to pump the gas to the shore, and
+one would not need to construct onshore production facilities.  This would
+significantly reduce the environmental footprint, and would help preserve
+marine and coastal environments.  Since an FLNG facility can be moved to a new
+location when a field has been depleted, it would make it economically viable
+to open up new business opportunities to develop offshore gas fields that would
+otherwise remain stranded.
+
+Moving the LNG production to an offshore facility presents a demanding set of
+challenges.  A particular challenge is that the elements of a conventional LNG
+facility need to fit into an area roughly one quarter the original size.  Heat
+exchangers are among the main challenges in the design and operation of LNG
+plants \cite{Hesselgreaves01}.  Compact and efficient heat exchangers are
+needed to obtain an energy efficient plant with low emissions.  More optimized
+designs require more accurate tools for design and operation.  Such tools can
+only come as a result of an improved physical understanding of the complex
+two-phase flows occurring in the heat exchangers.  This can be achieved by more
+detailed mathematical modelling, together with dedicated laboratory
+observations, cf.\ \cite{Olsen07}.
+
+\section{Overview of methods for two-phase flow simulations}
+In the following, a brief overview is given of different methods for modelling
+two-phase flows where the interface location is known.  In particular, we focus
+on methods that handle the interface evolution.  For more in-depth reviews, see
+for instance \cite{Cristini04,Scardovelli99,Sethian03}.
+
+Interface propagation methods comprise a range of methods that are often
+categorised as either front tracking or front capturing.  Front-tracking
+methods use Lagrangian particles to track the interface
+explicitly~\cite{Tryggvason01}, while front-capturing methods use an Eulerian
+approach to capture the interface implicitly.  Examples of the latter are
+volume-of-fluid methods~\cite{Scardovelli99,Tryggvason11}, phase-field
+methods~\cite{Anderson98,Jacqmin99,Lowengrub98}, and level-set
+methods~\cite{Osher03}.
+
+The main advantages of front-tracking methods are their inherent accuracy and
+that topological changes do not occur without explicit action.  Hence,
+unphysical numerical reconnection does not occur.  This means that if front
+tracking is used for the simulations of two drops that collide, these drops
+will not coalesce due to numerical reconnection or merging.  However, the
+handling of topological changes are challenging, in particular in three
+dimensions~\cite{Shin02}.  Also, there are some issues of numerical
+instabilities, as discussed by \citet{Sethian85} and \citet{Osher88}.
+
+The volume-of-fluid method utilizes a volume-fraction function whose values
+represent the characteristic function of one of the fluid domains.  Its values
+are zero or one, except in those cells cut by the interface.  A considerable
+advantage of the volume-of-fluid method is that it conserves the mass of both
+fluids well.  However, the reconstruction of the interface from volume
+fractions is not simple, and computation of geometric quantities such as the
+interface curvature is not straightforward.  Also, spurious bubbles and drops
+may be created, cf.\ \cite{Lafaurie94}.
+
+The phase-field methods treat the interface in a diffuse manner, where the
+fluid properties, such as density and viscosity, change rapidly but smoothly
+across the interface.  These methods typically solve the coupled
+Cahn-Hilliard/Navier-Stokes equations, where the Cahn-Hilliard equation is
+based on the free energy of an interface~\cite{Cahn57}.  Through this energy
+formulation, one can model more advanced interface physics such as van der
+Waals interactions, electrostatic forces, and fluids with varying
+miscibilities.  However, the phase-field methods require that one resolves very
+small length scales at the interfaces.  This poses a severe restriction on the
+applicability of phase-field methods for two-phase flow, where the length
+scales of the flow are generally much larger than those of the interface.
+
+In this thesis, we have used the level-set method~\cite{Osher88}, which
+implicitly captures the interface as an isocontour of a function defined in the
+entire domain.  The main motivation of this choice is both that the level-set
+method handles topological changes of evolving interfaces automatically,
+cf.~\citet{Sethian03}, and that it is relatively straightforward to implement.
+
+It should be noted that the automatic handling of topological changes is not
+based on physical principles.  For instance, when two interfaces approach each
+other and their distance becomes less than the spacing of the grid, the
+level-set method can no longer resolve both interfaces and so they are merged.
+An important consequence is that the level-set method does not model the
+physics involved in the coalescence process, and in particular in the smaller
+scales of the film-drainage process.  This process involves a wide range of
+length scales, varying from the nanometer scale where van der Waals force are
+active to the length scales of the external flow.  Some effort has been made to
+include the effects of the smaller scales in front-capturing methods,
+cf.~\cite{Nobari96,Tryggvason10}.  Recently, \citet{Kwakkel13} presented
+a level-set/volume-of-fluid method that is coupled with a film-drainage model
+that predicts if and when two colliding droplets will coalesce.  To prevent the
+numerical coalescence, each droplet has its own locally defined level-set
+function.
+
+The level-set method has been used to model several diverse phenomena,
+such as tumour growth~\cite{Macklin06,Macklin05,Macklin08}, propagation of
+wildland fire~\cite{Mallet09}, and computer RAM production~\cite{Melicher08}.
+For a good and thorough introduction to the level-set method, see
+\cite{Osher03}.
+
+A weakness of the level-set method is that it does not conserve the mass of the
+two fluids, in particular in areas of low resolution and/or high curvature.
+Different approaches have been developed to overcome this disadvantage, for
+example the conservative level-set method~\cite{Olsson05,Olsson07}, the
+particle level-set method~\cite{Enright02}, or the coupled
+level-set/volume-of-fluid method~\cite{Sussman00}.
+
+When we use the level-set method to capture the interface for immiscible and
+incompressible two-phase flow simulations, there will be a sharp change in the
+density and viscosity across the interface.  In this thesis we use the
+ghost-fluid method~\cite{Fedkiw99}, which is a sharp-interface method where the
+jumps are included in the spatial discretizations in a sharp manner.  An
+alternative method is the continuous surface-force method introduced by
+\citet{Brackbill92}, where the density and the viscosity are smeared out across
+the interface through a smoothed Heaviside function.

+\section{Goal and contribution of the present thesis}
+The main goal of the PhD project has been to develop fundamental knowledge of
+two-phase flow phenomenon that are relevant for compact heat exchangers.
+
+In order to do detailed theoretical studies of phenomena that are relevant for
+compact heat exchangers, we need to consider two-phase flows with mass and heat
+transfer in confined and complex geometries.  One such relevant phenomenon is
+the drop-film collision process \cite{Zhao09}.  Even when restricted to
+isothermal and immiscible flows, this simple phenomenon remains a challenge.
+When the level-set method is used to capture the interface, one must be
+particularly careful about how one calculates the interface curvature and
+normal vector.  For instance, when two drops are in near collision there is
+a kink region in the level-set function between the drops, where the gradient
+is discontinuous, see \cref{fig:curvature-problem}.  This discontinuity may
+lead to large errors in the curvature and the normal vector if it is not taken
+into account in the discretization stencils.

+
+As a step towards computing two-phase flow simulations in confined geometries,
+the thesis has considered the diffuse-domain method~\cite{Li09}.  This is
+a method where partial-differential equations in complex domains are extended
+into larger, regular domains with the use of diffuse approximations of the
+physical boundaries.  The approximations converge asymptotically to the
+original problem when the width of the diffuse boundary is reduced.  With this
+method one can use standard numerical methods to solve equations that
+incorporate complex boundaries.
+
+The main contributions of the present thesis are two new methods to calculate
+the curvature and normal vector in a robust manner with the level-set method.
+These methods are shown to yield more accurate calculations of drop-film and
+drop-drop collisions.  The methods are compared with standard methods and with
+other methods from the literature.
+
+In addition, the thesis presents an extension of a diffuse-domain method by
+a high-order correction term for the solution of elliptic problems in complex
+geometries.  New analysis provided in the thesis improves the understanding of
+the diffuse-domain method, and the derived method is shown to be more accurate
+than the existing diffuse-domain method.
+
+\section{Outline of the thesis}
+The thesis is organised as follows: \Cref{chap:two-phase-flow} gives a brief
+overview of the derivation of the governing equations for two-phase flow.  It
+includes a consideration of the fluid-fluid interface conditions and the
+derivation of a simplified jump tensor for the viscous term at the interface.
+
+\Cref{chap:numerical-methods} gives a detailed description of the numerical
+methods that are used to solve the two-phase flow equations.  In particular, it
+describes the level-set method, which is used to capture the interfaces,
+projection methods that are used to solve the Navier-Stokes equations, and the
+spatial and temporal discretization schemes.  At the end of the chapter, an
+overview of the novel discretization methods for the curvature and the normal
+vector is given.

+\chapter{Governing equations for two-phase flow}
+\label{chap:two-phase-flow}
+In this chapter we will give a brief overview of the derivation of the
+governing equations for two-phase flow.  We begin with a consideration of the
+Navier-Stokes equations for single-phase flow.  We then introduce a singular
+surface-force term and derive the Navier-Stokes equations for two-phase flow.
+Finally, we use the Navier-Stokes equations for two-phase flow to derive jump
+conditions at the interface between the phases.
+
+\section{The Navier-Stokes equations for single-phase flow}
+The following is a brief derivation of the Navier-Stokes equations for
+single-phase flows.  For a more thorough derivation of these equations, see for
+instance \citet[§4 and §5]{Aris89} or \citet[Chapter~4]{White03}.
+
+We consider a single-phase, viscous flow in some domain $\Omega$ with boundary
+$\partial\Omega$.  When temperature effects are neglected the flow is described
+by the Cauchy equation
+\begin{equation}
+  \label{eq:cauchy_equation}
+  \rho\left(\cd{\vct u}\right) = \div\tenstr+\rho\vct f,
+\end{equation}
+and the mass conservation equation,
+\begin{equation}
+  \label{eq:cons_of_mass}
+  \pdt\rho + \div(\rho\vct u) = 0.
+\end{equation}
+Here $\rho$ is the fluid density, $\vct u$ is the flow velocity, $t$ is time,
+$\tenstr$ is the stress tensor, $\vct f$ denotes body forces, and $\del$ is
+used to denote the gradient and divergence operators.  The stress tensor for
+Newtonian fluids with zero bulk viscosity is
+\begin{equation}
+  \tenstr = -p\tenI + 2\mu\tenD - \frac 2 3\mu (\trace\tenD) \tenI,
+  \label{eq:viscous_stress_tensor}
+\end{equation}
+where $p$ is the pressure, $\tenI$ is the identity tensor, $\mu$ is the dynamic
+viscosity, and $\trace\tenD$ denotes the trace of the strain-rate tensor
+$\tenD$,
+\begin{equation}
+  \tenD = \frac{1}{2}\left( \grad\vct u + (\grad\vct u)^T \right).
+  \label{eq:deformation_tensor}
+\end{equation}
+For incompressible flow, the mass-conservation equation reduces to
+\begin{equation}
+  \label{eq:navier-stokes-1}
+  \div\vct u = 0,
+\end{equation}
+that is, the velocity field must be divergence free.  If we further assume that
+the viscosity is constant, then it follows that the divergence of the stress
+tensor reduces to
+\begin{equation}
+  \label{eq:stress_tensor}
+  \div\tenstr = -\grad p + \mu\lapl\vct u,
+\end{equation}
+and so the Cauchy equation \eqref{eq:cauchy_equation} becomes
+\begin{equation}
+  \rho\left(\cd{\vct u}\right) = -\grad p + \mu\lapl\vct u + \rho\vct f.
+  \label{eq:navier-stokes-2}
+\end{equation}
+Equations \eqref{eq:navier-stokes-1} and \eqref{eq:navier-stokes-2} are the
+incompressible Navier-Stokes equations for single-phase flow with constant
+viscosity.
+
+\section{The Navier-Stokes equations for two-phase flow}
+We now consider an immiscible two-phase flow of two Newtonian fluids, each with
+its own viscosity and density.  We let $\Omega_1$ and $\Omega_2$ denote the
+domains occupied by fluid 1 and fluid 2, respectively, and let the interface
+between the fluids be denoted by $\Gamma$.  Then $\Omega
+= \Omega_1\cup\Omega_2$ and $\partial\Omega
+= (\partial\Omega_1\cup\partial\Omega_2)\setminus\Gamma$ are the fluid domain
+and its boundary, respectively.  See \cref{fig:domain} for an illustration of
+a two-phase flow domain.

+  \caption{An illustration of a two-phase flow domain.  The interface $\Gamma$
+    separates the two phases $\Omega_1$ and $\Omega_2$.}
+  \label{fig:domain}
+\end{figure}
+
+The extension of the single-phase model to account for two fluids can be made
+by adding a singular surface-force term to represent the effects of surface
+tension between the fluids.  We assume that the surface tension is constant, in
+which case the singular surface force can be defined as
+\begin{equation}
+  \funssf(\vct x,t)
+  = \int_{\Gamma}\sigma\kappa\vct n\delta(\vct x - \vct x_I(\vct s))\dif\vct s,
+  \label{eq:ssf}
+\end{equation}
+where $\sigma$ is the surface tension, $\kappa$ is the local curvature, $\vct
+n$ is the normal vector, $\delta$ is the Dirac delta function, and $\vct
+x_I(\vct s)$ is a parametrisation of the interface.  Thus the Navier-Stokes
+equations for immiscible and incompressible two-phase flow are
+\begin{align}
+  \label{eq:ns1}
+  \div\vct u &= 0, \\
+  \label{eq:ns2}
+  \rho\left(\cd{\vct u}\right) &= -\grad p + \mu\lapl\vct u
+    + \rho\vct f + \funssf.
+\end{align}
+
+\section{Fluid-fluid interface conditions}
+The surface-tension force and the jump in viscosity and density across the
+interface $\Gamma$ lead to a set of interface conditions that must be satisfied
+along the interface $\Gamma$.  The following is a brief derivation of these
+conditions.
+
+First, we only consider flows where there is no mass transfer, which implies
+that
+\begin{equation}
+  \jmp{\vct u}\cdot\vct n = 0,
+\end{equation}
+where $\jmp{\cdot}$ denotes the jump at the interface, for instance $\jmp{\mu}
+= \mu_2 - \mu_1$.  Further, for viscous flows there is no slip at the
+interface, and thus the tangential velocity component of the two fluids must be
+equal at the interface,
+\begin{equation}
+  \jmp{\vct u}\cdot\vct t = 0.
+\end{equation}
+It follows that
+\begin{align}
+  \label{eq:jmpu}
+  \jmp{\vct u} &= 0, \\
+  \label{eq:jmpJut}
+  \jmp{\grad \vct u}\cdot\vct t &= 0.
+\end{align}
+The latter is a direct consequence of the former.  Both fluids are
+incompressible, which gives the trivial identity $\jmp{\div\vct u} = 0$.  If we
+use the identity
+\begin{equation}
+  \div\vct u
+    = \vct n\cdot\grad\vct u\cdot\vct n + \vct t\cdot\grad\vct u\cdot\vct t
+  \label{eq:divuident}
+\end{equation}
+together with \eqref{eq:jmpJut} we get
+\begin{equation}
+  \vct n\cdot\jmp{\grad\vct u}\cdot\vct n = 0,
+  \label{eq:jmpngradun}
+\end{equation}
+which means that the normal component of the normal derivative of the velocity
+field is continuous across the interface.  Note that in \eqref{eq:divuident}
+and in similar expressions in the following, the nabla operator is only applied
+to $\vct u$, not the normal and tangential vectors that follow.

+  \caption{A sketch of the control volume $\Omega_\epsilon$ that covers the
+    interface, $\Gamma$.}
+  \label{fig:domain_omega_epsilon}
+\end{figure}%
+Next, we consider the conservation of momentum.  We define a control volume
+\begin{equation}
+  \Omega_{\epsilon} = \set{\vct x \in \Omega}{\min_{\vct x_I \in \Gamma}|\vct
+    x - \vct x_I| \leq \epsilon},
+\end{equation}
+where $\epsilon > 0$, see \cref{fig:domain_omega_epsilon}.  We then integrate
+the Cauchy equation \eqref{eq:cauchy_equation} with the added singular
+surface-force term over the domain~$\Omega_\epsilon$,
+\begin{multline}
+  \intoepdx{\rho\td{\vct u}}
+    = \intoepdx{\div\tenstr} + \intoepdx{\rho\vct f} \\
+      + \intoepdx{ \int_{\Gamma}\sigma\kappa\vct n\delta(\vct x - \vct
+        x_I(\vct s))\dif\vct s}.
+\end{multline}
+Here $\tdi{\vct u} = \partial\vct u/\partial t + \vct u\cdot\grad\vct u$
+denotes the convective derivative.  Now we apply the Gauss theorem and change
+the order of integration in the last term to obtain
+\begin{equation}
+  \intoepdx{\rho\td{\vct u}} = \intdoepds{\tenstr\cdot\vct n}
+    + \intoepdx{\rho\vct f} + \int_\Gamma\sigma\kappa\vct n\dif\vct s.
+\end{equation}
+If we let $\epsilon$ go to zero, the left-hand side and the second term on the
+right-hand side vanish, and we get
+\begin{equation}
+  0 = \int_\Gamma\left( \jmp{\tenstr}\cdot\vct n + \sigma\kappa\vct
+    n \right)\dif s.
+  \label{eq:stressjumpint}
+\end{equation}
+Since the derivation above is also valid for any subset of $\Omega_\epsilon$
+containing a part of $\Gamma$, \eqref{eq:stressjumpint} must hold for any part
+of $\Gamma$.  Therefore
+\begin{equation}
+  0 = \jmp{\vct T}\cdot\vct n + \sigma\kappa\vct n.
+\end{equation}
+With $\vct T = -p\vct I + 2\mu\vct D$ we finally get the interface condition
+for the stresses,
+\begin{equation}
+  \label{eq:stress_jump}
+  \jmp{p}\vct n - \jmp{2\mu\tenD}\cdot\vct n = \sigma\kappa\vct n.
+\end{equation}
+The surface tension force is seen to introduce a discontinuity in the normal
+stresses across the interface.  The tangential stresses are continuous.
+
+\section{Interface conditions for the pressure and the viscous term}
+The previous section gave a brief derivation of the interface conditions for
+immiscible and incompressible two-phase flow without mass transfer.  In order
+to use these conditions for the discretization of the Navier-Stokes equations
+\eqref{eq:ns1} and \eqref{eq:ns2}, we need to rewrite them into a more suitable
+form.  In particular, we want to find explicit expressions for the jump in the
+pressure $\jmp p$ and the viscous term $\jmp{\mu\grad\vct u}$.  The following
+derivation is based on \cite{Hansen05} and \cite{Kang00}.
+
+First, a jump condition for the pressure is obtained by taking the inner
+product of \eqref{eq:stress_jump} with the normal vector $\vct n$,
+\begin{equation}
+  \jmp p = \vct n\cdot\jmp{2\mu\tenD}\cdot\vct n + \sigma\kappa
+      = 2\jmp{\mu}\vct n\cdot \grad\vct u \cdot\vct n
+        + \sigma\kappa,
+  \label{eq:jump_pressure}
+\end{equation}
+where \eqref{eq:jmpngradun} was used for the second equality.
+
+To find the jump in the viscous term, it is first decomposed into an interface
+normal coordinate system as
+\begin{equation}
+  \begin{split}
+    \jmp{\mu\grad\vct u} &=
+  \left(\vct n\cdot\jmp{\mu\grad\vct u}\cdot\vct n\right)\vct n\otimes\vct n +
+  \left(\vct t\cdot\jmp{\mu\grad\vct u}\cdot\vct t\right)\vct t\otimes\vct t
+        \\ &\quad+
+  \left(\vct n\cdot\jmp{\mu\grad\vct u}\cdot\vct t\right)\vct n\otimes\vct t +
+  \left(\vct t\cdot\jmp{\mu\grad\vct u}\cdot\vct n\right)\vct t\otimes\vct n,
+  \end{split}
+\end{equation}
+where $\otimes$ denotes the dyadic product.  We already showed that
+$\jmp{\grad\vct u}\cdot\vct t = 0$ and $\vct n\cdot\jmp{\grad\vct u}\cdot\vct
+n = 0$, cf.\ \eqref{eq:jmpJut} and \eqref{eq:jmpngradun}, which gives
+\begin{align}
+  \vct n\cdot\jmp{\mu\grad\vct u}\cdot\vct n &=
+    \jmp{\mu}\,\vct n\cdot\grad\vct u\cdot\vct n, \\
+  \vct t\cdot\jmp{\mu\grad\vct u}\cdot\vct t &=
+    \jmp{\mu}\,\vct t\cdot\grad\vct u\cdot\vct t, \\
+  \vct n\cdot\jmp{\mu\grad\vct u}\cdot\vct t &=
+    \jmp{\mu}\,\vct n\cdot\grad\vct u\cdot\vct t.
+\end{align}
+We then take the inner product of \eqref{eq:stress_jump} with $\vct t$, which
+gives
+\begin{equation}
+  \vct t\cdot\jmp{\mu\left(\grad\vct u + (\grad\vct u)^T \right)}\cdot\vct n
+  = \vct t\cdot\jmp{\mu\grad\vct u} \cdot\vct n
+    + \jmp{\mu}\vct n\cdot\grad\vct u \cdot\vct t
+  = 0,
+\end{equation}
+or
+\begin{equation}
+  \vct t\cdot\jmp{\mu\grad\vct u}\cdot\vct n =
+    - \jmp{\mu}\vct n\cdot\grad\vct u \cdot\vct t.
+\end{equation}
+The jump in the viscous term becomes
+\begin{multline}
+  \jmp{\mu\grad\vct u} = \jmp{\mu} \Big(
+       (\vct n\cdot\grad\vct u\cdot\vct n)\vct n\otimes\vct n
+     + (\vct n\cdot\grad\vct u\cdot\vct t)\vct n\otimes\vct t \\
+     - (\vct n\cdot\grad\vct u\cdot\vct t)\vct t\otimes\vct n
+     + (\vct t\cdot\grad\vct u\cdot\vct t)\vct t\otimes\vct t \Big).
+\end{multline}
+This can be simplified further by noting that
+\begin{equation}
+  (\grad\vct u\cdot t)\otimes\vct t
+  = (\vct n\cdot\grad\vct u\cdot\vct t)\vct n\otimes\vct t
+    + (\vct t\cdot\grad\vct u\cdot\vct t)\vct t\otimes\vct t.
+\end{equation}
+Thus we obtain the expression for the jump in the viscous term that has been
+used in the present work,
+\begin{multline}
+  \jmp{\mu\grad\vct u} = \jmp{\mu} \Big(
+       (\vct n\cdot\grad\vct u\cdot\vct n)\vct n\otimes\vct n
+     - (\vct n\cdot\grad\vct u\cdot\vct t)\vct t\otimes\vct n \\
+     + (\grad\vct u\cdot\vct t)\otimes\vct t \Big).
+  \label{eq:jumptens}
+\end{multline}
+
+\section{Summary}

+\chapter{Numerical methods}
+\label{chap:numerical-methods}
+This chapter describes the numerical methods that have been used in this thesis
+to solve the Navier-Stokes equations for two-phase flow.  First, a brief
+introduction to the level-set method is given, which is followed by an outline
+of the two projection methods that have been used to solve the Navier-Stokes
+equations.  The spatial and temporal discretization methods are then
+summarized, and at the end of the chapter the new methods to calculate the
+curvature and the normal vectors are presented.
+
+\section{The level-set method}
+\label{sec:level-set}
+In order to solve the Navier-Stokes equations for two-phase flow, we need to
+know the location of the interface.  The level-set method proposed by
+\citet{Osher88} allows us to capture the interface location as the zero level
+set of the level-set function $\varphi(\vct x,t)$.  The level-set function is
+typically defined as a signed-distance function,
+\begin{equation}
+  \varphi(\vct x,t) = \begin{cases}
+     d(\vct x,t) & \text{if } \vct x\in\Omega_2, \\
+    -d(\vct x,t) & \text{if } \vct x\in\Omega_1, \\
+  \end{cases}
+\end{equation}
+where $d(\vct x,t)$ is the shortest distance to the interface $\Gamma$,
+\begin{equation}
+  d(\vct x,t) = \min_{\vct x_I \in \Gamma} |\vct x - \vct x_I|.
+\end{equation}
+Thus the interface can be defined implicitly as
+\begin{equation}
+  \Gamma(t) = \set{\vct x\in\Omega}{\varphi(\vct x,t)=0},
+              \quad t\in \mathbb R^+.
+\end{equation}
+
+The position of the interface is updated by solving an advection equation for
+$\varphi$,
+\begin{equation}
+  \label{eq:ls_adeq}
+  \pdt{\varphi} + \vct{\hat u}\cdot\grad\varphi = 0,
+\end{equation}
+where $\vct{\hat u}$ is the velocity at the interface extended to the entire
+domain.  We extend the interface velocity through solving
+a velocity-extrapolation equation,
+\begin{equation}
+  \label{eq:ls_velextr}
+  \pd{\vct{\hat u}}{\tau} + S(\varphi)\vct n\cdot\grad\vct{\hat u} = 0,
+  \quad \vct{\hat u}_{\tau=0} = \vct u,
+\end{equation}
+to steady state, cf.\ \cite{Adalsteinsson99,Zhao96}.  Here $\tau$ is
+a pseudo-time and $S$ is a smeared sign function which is equal to zero at the
+interface,
+\begin{equation}
+  S(\varphi) = \frac{\varphi}{\sqrt{\varphi^2+2\Delta x^2}}.
+\end{equation}
+
+When we solve the level-set equation \eqref{eq:ls_adeq}, the non-uniform
+advection will distort the signed-distance property of the level-set function,
+and numerical dissipation error adds to this distortion.  The level-set
+function is therefore reinitialized regularly by solving
+\begin{equation}
+  \label{eq:ls_reinit}
+  \begin{split}
+    \pd{\varphi}{\tau} + S(\varphi_0)(|\grad\varphi|-1) &= 0, \\
+    \varphi(\vct x,0) &= \varphi_0(\vct x),
+  \end{split}
+\end{equation}
+to steady state as proposed by \citet{Sussman94}.  The level-set function just
+before initialization is used as the initial condition $\varphi_0$.
+
+The level-set equations \eqref{eq:ls_adeq}, \eqref{eq:ls_velextr}, and
+\eqref{eq:ls_reinit} are discretized in time and space as described in the
+following sections.  The method presented by \citet{Adalsteinsson95} is used to
+improve the computational speed.  The method is often called the narrow-band
+method, since the level-set function is only updated in a narrow band across
+the interface at each time step.
+
+One of the advantages of the level-set method is that normal vectors and
+curvatures can be readily calculated from the level-set function, that is,
+\begin{align}
+  \label{eq:norm}
+  \vct n &= \frac{\grad\varphi}{|\grad\varphi|}, \\
+  \label{eq:curv}
+  \kappa &= \div\left(\frac{\grad\varphi}{|\grad\varphi|}\right).
+\end{align}
+
+\section{Projection methods}
+\label{sec:projection-method}
+We have employed two different projection methods in this thesis to solve the
+incompressible Navier-Stokes equations for two-phase flow \eqref{eq:ns1} and
+\eqref{eq:ns2}.  Papers A, B, and C used the direct projection
+scheme~1~(DP1)~\cite{Hansen05}, and Paper D used the more standard Chorin
+projection method \cite{Chorin68}.
+
+The projection methods are a family of methods for the solution of the
+incompressible Navier-Stokes equations that are based on the Helmholtz-Hodge
+theorem.  This theorem states that an arbitrary vector field can be decomposed
+into a divergence-free part and a rotation-free part.  That is, any vector
+field $\vct a$ can be written as
+\begin{equation}
+  \vct a = \vct a' + \grad\psi,
+\end{equation}
+where $\vct a'$ is a vector with $\div\vct a' = 0$ and $\psi$ is a scalar
+potential.  The proof of this theorem can be found in for instance
+\cite[§3.44]{Aris89} or \cite{Chorin00}.
+
+\subsection{The direct projection scheme 1}
+The DP1 was developed by \citet{Hansen05} and is based on a direct application
+of the Helmholtz-Hodge theorem.  We assume that the velocity $\vct u$ is
+sufficiently smooth, and then rewrite \eqref{eq:navier-stokes-2} to get
+\begin{equation}
+  \label{eq:divFreeVel}
+  \pdt{\vct u} = \vct w - \frac{\grad p}{\rho},
+\end{equation}
+where
+\begin{equation}
+  \vct w = - (\vct u\cdot\grad)\vct u + \nu\grad^2\vct u + \vct f.
+  \label{eq:continuousRightHandVector}
+\end{equation}
+The divergence of \eqref{eq:divFreeVel} yields a Poisson equation for the
+pressure,
+\begin{equation}
+  \div\left(\frac{\grad p}{\rho}\right) = \div\vct w.
+  \label{eq:PoissonDP1}
+\end{equation}
+The DP1 scheme follows from a direct numerical discretization of the above
+equations.  First, $\vct w$ is calculated with
+\eqref{eq:continuousRightHandVector}.  Then the pressure is found by solving
+the Poisson equation \eqref{eq:PoissonDP1}.  Finally, an Euler step is used to
+solve \eqref{eq:divFreeVel}, that is,
+\begin{equation}
+  \vct u^{n+1} = \vct u^n + \Delta t\left(\vct w - \frac{\grad p}{\rho}\right).
+  \label{eq:dp1-update}
+\end{equation}
+
+\subsection{The Chorin projection method}
+The Chorin projection method was presented by \citet{Chorin68}, and is today
+one of the standard methods for solving the Navier-Stokes equations, e.g.\
+\cite{Walker12}.  The method is briefly presented in the following.
+
+Let $\Delta t$ be the time step, and consider the discretization of the
+momentum equation \eqref{eq:navier-stokes-2} with the forward Euler method,
+\begin{equation}
+  \frac{\vct u^{n+1} - \vct u^n}{\Delta t}
+  = -\vct u^n\cdot\grad\vct u^n
+    - \frac{\grad p^{n+1}}{\rho} + \frac\mu\rho\lapl\vct u^n + \vct f,
+  \label{eq:discmomeq}
+\end{equation}
+where $\vct u^n\equiv\vct u(\vct x,n\Delta t)$ and $p^n\equiv p(\vct x,n\Delta
+t)$ are assumed known at time level $n$.  Note that the pressure gradient is
+evaluated at time level $n+1$.  Next, to solve \eqref{eq:discmomeq} in two
+steps, we introduce the intermediate velocity field $\vct u^\star$,
+\begin{equation}
+  \frac{\vct u^{n+1} - \vct u^\star + \vct u^\star - \vct u^n}{\Delta t}
+  = -\vct u^n\cdot\grad\vct u^n
+    - \frac{\grad p^{n+1}}{\rho} + \frac\mu\rho\lapl\vct u^n + \vct f,
+\end{equation}
+which is chosen such that
+\begin{align}
+  \label{eq:ustar}
+  \frac{\vct u^\star - \vct u^n}{\Delta t}
+    &= -\vct u^n\cdot\grad\vct u^n + \frac\mu\rho\lapl\vct u^n + \vct f, \\
+  \label{eq:unext}
+  \frac{\vct u^{n+1} - \vct u^\star}{\Delta t} &= - \frac{\grad p^{n+1}}{\rho}.
+\end{align}
+From \eqref{eq:ustar} we get an explicit expression for $\vct u^\star$,
+\begin{equation}
+  \vct u^{\star} = \vct u^n
+    + \Delta t\left(-\vct u^n\cdot\grad\vct u^n
+        + \frac\mu\rho\,\lapl\vct u^n + \vct f\right).
+\end{equation}
+Next, the divergence of \eqref{eq:unext} and $\div\vct u^{n+1} = 0$ yields
+a Poisson equation for the pressure,
+\begin{equation}
+  \div\left(\frac{\grad p^{n+1}}{\rho}\right)
+    = \frac{\div\vct u^\star}{\Delta t}.
+  \label{eq:PoissonChorin}
+\end{equation}
+Finally, we obtain for \eqref{eq:unext}
+\begin{equation}
+  \vct u^{n+1} = \vct u^\star - \Delta t\frac{\grad p^{n+1}}{\rho}.
+  \label{eq:velcorrection}
+\end{equation}
+
+\section{Spatial discretization}
+\label{sec:x-discr}
+The governing equations \eqref{eq:ns1}, \eqref{eq:ns2}, \eqref{eq:ls_adeq},
+\eqref{eq:ls_velextr}, and \eqref{eq:ls_reinit} are discretized on a staggered
+grid~\cite{Harlow65}, where the scalar values are located at the cell centres
+and the vector values are located at the cell edges, see
+\cref{fig:staggered-grid}.  The domain boundary coincides with cell edges, and
+the fixed grid spacing is $\Delta x$ in the $x$ direction and $\Delta y$ in the
+$y$ direction.

+  \label{fig:staggered-grid}
+\end{figure}
+
+The $x$- and $y$-derivatives, divergence, and Laplacian operators are
+discretized by the second-order central-difference scheme,
+\begin{align}
+  \left. G_x p \right|_{i+\frac 1 2,j}
+    &= \frac{p_{i+1,j} - p_{i,j}}{\Delta x}, \\
+  \left. G_y p \right|_{i,j+\frac 1 2}
+    &= \frac{p_{i,j+1} - p_{i,j}}{\Delta y}, \\
+  \left. \vct D \cdot \vct u \right|_{i,j}

+       + \frac{p_{i,j+1} - 2p_{i,j} + p_{i,j-1}}{(\Delta y)^2},
+\end{align}
+respectively.  Here $\vct u = (u,v)$ is a vector and $p$ is a scalar.  Note
+that the gradient of a scalar is a vector and has values located at the cell
+edges.  These definitions are consistent with the staggered grid, since the
+gradient returns a vector with components defined on the cell faces, while the
+divergence and the Laplacian returns a scalar defined at the cell centres.
+
+\subsection{Advective terms}
+The advective terms, $\vct u\cdot\grad\vct u$ in the momentum equation
+\eqref{eq:ns2} and $\vct{\hat u}\cdot\grad\varphi$ in the level-set equation
+\eqref{eq:ls_adeq}, and the normal derivative $\vct n\cdot\grad\vct{\hat u}$ in
+the velocity-extrapolation equation \eqref{eq:ls_velextr} are discretized with
+the weighted essentially non-oscillatory (WENO) scheme, cf.~\cite{Fedkiw99}
+and~\cite{Jiang96}.  The WENO scheme is a high-order upwind scheme that is
+fifth-order accurate in smooth regions.  In nonsmooth regions the accuracy is
+reduced to a minimum of third order.  The following is a brief outline of the
+WENO scheme.
+
+First, when we calculate the advective term for the velocity, the vector
+components are required on all cell edges.  That is, we must interpolate the
+$x$-component of the velocity to the location of the $y$-component of the
+velocity and vice versa.  To do this we use a linear interpolation,
+\begin{align}
+  u_{i,j+\frac 1 2} &= \frac 1 4\left(
+      u_{i-\frac 1 2,j  } + u_{i-\frac 1 2,j+1}
+    + u_{i+\frac 1 2,j+1} + u_{i+\frac 1 2,j  } \right), \\
+  v_{i+\frac 1 2,j} &= \frac 1 4\left(
+      v_{i,  j-\frac 1 2} + v_{i+1,j-\frac 1 2}
+    + v_{i+1,j+\frac 1 2} + v_{i  ,j+\frac 1 2} \right).
+\end{align}
+
+Similarly, when we calculate the advective term for the level-set function
+$\varphi$, we first interpolate the velocity to the scalar grid,
+\begin{align}
+  u_{i,j} &= \frac 1 2\left( u_{i+\frac 1 2,j} + u_{i-\frac 1 2,j} \right), \\
+  v_{i,j} &= \frac 1 2\left( v_{i,j+\frac 1 2} + v_{i,j-\frac 1 2} \right).
+\end{align}
+
+We now consider the WENO scheme for the advective operator in 1D at the point
+$x_{i+\frac 1 2}$.  The scheme extends naturally to higher dimensions.  First,
+if $u_{i+\frac 1 2} = 0$, then
+\begin{equation}
+  \left. u\pd u x \right|_{i+\frac 1 2} = 0.
+\end{equation}
+Otherwise we need to calculate a set of five differences that depend on the
+upwind direction.  The differences are denoted $\Delta v_k$ for $k=1,\dots,5$.
+If $u_{i+\frac 1 2}>0$, then we calculate
+\begin{equation}
+  \Delta v_k = \frac{u_{i+\frac{2k-5} 2} - u_{i+\frac{2k-7} 2}}{\Delta x}.
+\end{equation}
+Otherwise if $u_{i+\frac 1 2}<0$, we calculate
+\begin{equation}
+  \Delta v_k = \frac{u_{i-\frac{2k-9} 2} - u_{i-\frac{2k-7} 2}}{\Delta x}.
+\end{equation}
+Next we calculate expressions for the smoothness of three substencils,
+\begin{align}
+  S_1 &= \frac{13}{12}(\Delta v_1 - 2\Delta v_2 + \Delta v_3)^2
+    + \frac 1 4 (\Delta v_1 - 4\Delta v_2 + 3\Delta v_3)^2, \\
+  S_2 &= \frac{13}{12}(\Delta v_2 - 2\Delta v_3 + \Delta v_4)^2
+    + \frac 1 4 (\Delta v_2 - \Delta v_4)^2, \\
+  S_3 &= \frac{13}{12}(\Delta v_3 - 2\Delta v_4 + \Delta v_5)^2
+    + \frac 1 4 (3\Delta v_3 - 4\Delta v_4 + \Delta v_5)^2,
+\end{align}
+where a small $S$ indicates a smooth substencil.  These smoothness factors are
+then used to compute weights for the substencils,
+\begin{equation}
+  w_k = \frac{b_k}{b_1+b_2+b_3},
+\end{equation}
+for $k = 1,2,3$, where
+\begin{equation}
+  b_1 = \frac 1 {10}\frac 1 {(\epsilon+S_1)^2},\quad
+  b_2 = \frac 6 {10}\frac 1 {(\epsilon+S_2)^2},\quad
+  b_3 = \frac 3 {10}\frac 1 {(\epsilon+S_3)^2}.
+\end{equation}
+Here $\epsilon$ is a regularization parameter that is used to avoid division by
+zero.  We have used $\epsilon = 10^{-6}$ in this work.  Finally, the WENO
+scheme for the gradient becomes
+\begin{multline}
+  \left. \pd u x \right|_{i+\frac 1 2} \simeq
+      w_1\left(\frac 1 3\Delta v_1 - \frac 7 6\Delta v_2
+        + \frac{11} 6 \Delta v_3\right) \\
+    + w_2\left(-\frac 1 6\Delta v_2 + \frac 5 6\Delta v_3
+        + \frac 1 3 \Delta v_4\right) \\
+    + w_3\left(\frac1 3\Delta v_3 + \frac 5 6\Delta v_4
+        - \frac 1 6 \Delta v_5\right).
+\end{multline}
+
+\subsection{The viscous term}
+The viscous term $\mu\lapl\vct u$ in the Navier-Stokes equations is discretized
+by standard second-order central differences using the ghost-fluid method
+(GFM)~\cite{Fedkiw99,Kang00,Liu00}.  This method includes the jump in the
+viscous term at the interface \eqref{eq:jumptens} in the discretization stencil
+in a sharp manner.
+
+In the following we present the GFM scheme in the one-dimensional case.  The
+extension to higher dimensions is straightforward.  In order to simplify the
+notation, we omit the half indices and let $k\equiv i+\frac 1 2$.  Further, we
+consider a general case where
+\begin{equation}
+  \jmp u = a_\Gamma, \qquad \jmp{\mu\pd u x} = b_\Gamma.
+\end{equation}
+For the viscous term, $a_\Gamma = 0$, cf.\ \eqref{eq:jmpu}, and $b_\Gamma$ is
+given by the jump tensor~\eqref{eq:jumptens}.  The jump tensor is calculated at
+the cell centres near the interface with the second-order central-difference
+scheme.  It is then interpolated linearly to the cell edges, from where it is
+again interpolated linearly to the interface when needed.
+
+If the interface does not cross the stencil, then the GFM scheme reduces to the
+standard second-order central-difference stencil.  Else there are four
+stencils, depending on the location of the interface.  One such interface
+configuration is sketched in \cref{fig:gfm-scheme-example}.  In all the
+stencils, $\theta$ is defined as the relative distance from the interface to
+the node on the left, for instance
+\begin{equation}
+  \theta = \frac{|\varphi_{k}|}{|\varphi_{k}| + |\varphi_{k+1}|},
+\end{equation}
+where $\varphi_k$ and $\varphi_{k+1}$ are the level-set function values
+linearly interpolated to the vector grid.  The four stencils are given below,
+where $h\equiv\Delta x$.
+\begin{enumerate}
+  \item Phase 1 is to the left and interface lies between $k$ and $k+1$:
+    \begin{align}
+      \begin{split}
+        \left.\pd{} x\left(\mu\pd u x\right)\right|_{x_k}
+          &= \frac{\hat\mu\left(u_{k+1} - u_{k}\right)
+                 - \mu_1\left(u_{k} - u_{k-1}\right)}{h^2} \\
+          &\qquad
+             - \frac{\hat\mu a_\Gamma}{h^2}
+             - \frac{\hat\mu b_\Gamma (1-\theta)}{\mu_2 h},
+      \end{split} \\
+       \hat\mu &= \frac{\mu_1\mu_2}{\theta\mu_2 + (1-\theta)\mu_1}.
+    \end{align}
+  \item Phase 1 is to the left and interface lies between $k-1$ and $k$:
+    \begin{align}
+      \begin{split}
+        \left.\pd{} x\left(\mu\pd u x\right)\right|_{x_k}
+          &= \frac{\mu_2\left(u_{k+1} - u_{k}\right)
+                - \hat\mu\left(u_{k} - u_{k-1}\right)}{h^2} \\
+          &\qquad
+            + \frac{\hat\mu a_\Gamma}{h^2}
+            - \frac{\hat\mu b_\Gamma \theta}{\mu_1 h},
+      \end{split} \\
+      \hat\mu &= \frac{\mu_1\mu_2}{\theta\mu_2 + (1-\theta)\mu_1}.
+    \end{align}
+  \item Phase 2 is to the left and interface lies between $k$ and $k+1$:
+    \begin{align}
+      \begin{split}
+        \left.\pd{} x\left(\mu\pd u x\right)\right|_{x_k}
+          &= \frac{\hat\mu\left(u_{k+1} - u_{k}\right)
+                - \mu_2\left(u_{k} - u_{k-1}\right)}{h^2} \\
+          &\qquad
+            + \frac{\hat\mu a_\Gamma}{h^2}
+            + \frac{\hat\mu b_\Gamma (1-\theta)}{\mu_1 h},
+      \end{split} \\
+      \hat\mu &= \frac{\mu_1\mu_2}{\theta\mu_1 + (1-\theta)\mu_2}.
+    \end{align}
+  \item Phase 2 is to the left and interface lies between $k-1$ and $k$:
+    \begin{align}
+      \begin{split}
+        \left.\pd{} x\left(\mu\pd u x\right)\right|_{x_k}
+          &= \frac{\mu_1\left(u_{k+1} - u_{k}\right)
+                - \hat\mu\left(u_{k} - u_{k-1}\right)}{h^2} \\

+      \end{split} \\
+      \hat\mu &= \frac{\mu_1\mu_2}{\theta\mu_1 + (1-\theta)\mu_2}.

+\subsection{Pressure Poisson equation}
+\label{sec:pressure-poisson}
+The Laplace operator in the Poisson equations \eqref{eq:PoissonDP1} and
+\eqref{eq:PoissonChorin} is also discretized by standard second-order central
+differences using the GFM~\cite{Kang00,Liu00}.  The GFM was discussed in the
+previous section, where stencils were given for the viscous term in the
+one-dimensional case.  For the pressure, the stencils are the same except we
+use $p$ instead of $u$, and $1/\rho$ and $1/\hat\rho$ instead of $\mu$ and
+$\hat\mu$.  To find the jump in the pressure at the interface, $\jmp
+p = a_\Gamma$, the jump condition \eqref{eq:jump_pressure} is calculated at the
+cell centres and then interpolated to the interface.  In addition, we use that
+$b_\Gamma = 0$, which is justified by \citet[Section~3.7]{Kang00}.
+
+The resulting linear system for the pressure is solved with a solver from the
+Portable, Extensible Toolkit for Scientific Computation (PETSc)~\cite{PETSc}.
+PETSc makes available a large selection of solvers.  In most cases, we used the
+direct solver based on LU factorisation or the conjugate gradient method with
+incomplete Cholesky factorisation.  In some cases, we used the GMRES solver
+with a preconditioner, either incomplete LU factorisation or an algebraic
+multigrid method.  See \cite{PETSc} for more details and a list of available
+methods, and see for example~\cite{Iserles09} or~\cite{Saad03} for an
+introduction to linear solvers.
+
+Finally, the gradient of the pressure, used in \eqref{eq:divFreeVel} and
+\eqref{eq:velcorrection}, is also calculated with the GFM.  In one dimension,
+the stencil is
+\begin{align}
+  \left. \frac 1 \rho \pd p x\right|_{i+\frac 1 2}
+           &= \frac 1 {\hat\rho} \frac{(p_{i+1} - a_\Gamma) - p_i} h, \\
+  \hat\rho &= \theta\rho_1 + (1-\theta)\rho_2,
+\end{align}
+if $\phi_i\leq 0$ and $\phi_{i+1}>0$, or else
+\begin{align}
+  \left. \frac 1 \rho \pd p x\right|_{i+\frac 1 2}
+           &= \frac 1 {\hat\rho} \frac{(p_{i+1} + a_\Gamma) - p_i} h, \\
+  \hat\rho &= \theta\rho_2 + (1-\theta)\rho_1,
+\end{align}
+where
+\begin{equation}
+  \theta = \frac{|\varphi_{i}|}{|\varphi_{i}| + |\varphi_{i+1}|}.
+\end{equation}
+
+\section{Temporal discretization}
+\label{sec:t-discr}
+The temporal discretization is done with the explicit strong
+stability-preserving Runge-Kutta (SSP-RK) schemes, see
+\cite{Ketcheson05,Shu88}.  The idea behind the SSP-RK schemes is to preserve
+the stability of a low-order method when it is extended to higher order.  It is
+argued in \cite{Gottlieb01} that if one extends the forward Euler method, which
+is total variation diminishing (TVD) for a suitable discretization of a scalar
+conservation law, to a non-SSP higher-order method, then overshoots may occur
+at discontinuities.
+
+An SSP-RK method can be written as a convex sum of explicit Euler steps with
+time step $\Delta t$,
+\begin{equation}
+  \mathcal E\left(x^n\right) = x^n + \Delta t \mathcal F(x^n,t^n).
+\end{equation}
+where $\mathcal F$ is the residual of the PDE to be solved.  In this thesis we
+have used two methods:  The third-order three-stage SSP-RK method~\cite{Shu88},
+\begin{equation}
+  \begin{split}
+    x^{(1)} &= \mathcal E\left(x^n\right), \\
+    x^{(2)} &= \frac 3 4 x^n + \frac 1 4\mathcal E\left(x^{(1)}\right), \\
+    x^{n+1} &= \frac 1 3 x^n + \frac 2 3\mathcal E\left(x^{(2)}\right),
+  \end{split}
+  \label{eq:ssprk33}
+\end{equation}
+and the third-order four-stage SSP-RK method~\cite{Kraaijevanger91},
+\begin{equation}
+  \begin{split}
+    x^{(1)} &= \frac 1 2 x^n + \frac 1 2\mathcal E\left(x^n\right), \\
+    x^{(2)} &= \frac 1 2 x^{(1)} + \frac 1 2\mathcal E\left(x^{(1)}\right), \\
+    x^{(3)} &= \frac 2 3 x^n + \frac 1 6 x^{(2)}
+               + \frac 1 6\mathcal E\left(x^{(2)}\right), \\
+    x^{n+1} &= \frac 1 2 x^{(3)} + \frac 1 2\mathcal E\left(x^{(3)}\right).
+  \end{split}
+  \label{eq:ssprk34}
+\end{equation}
+
+The semi-discretized velocity-extrapolation equation \eqref{eq:ls_velextr} and
+level-set reinitialization equation \eqref{eq:ls_reinit} can be written as
+systems of ordinary differential equations (ODEs) of the form
+\begin{equation}
+  \od{\vct \psi} \tau = \vct F(\vct\psi,\tau),
+\end{equation}
+where $\vct\psi$ is a vector containing the discrete variables and $\vct F$
+contains the spatially discretized terms.  The explicit Euler step becomes
+\begin{equation}
+  \mathcal E(\vct\psi^n) = \vct\psi^n + \Delta\tau \vct F(\vct\psi^n,\tau^n).
+\end{equation}
+In this thesis, these equations are solved with the third-order four-stage
+SSP-RK method \eqref{eq:ssprk34}.  The four-stage method is used because it is
+more accurate than the three-stage method.  We wanted to make sure that the
+error is mainly dominated by the spatial discretization.
+
+The semi-discretized Navier-Stokes equations \eqref{eq:navier-stokes-1} and
+\eqref{eq:navier-stokes-2} are solved together with the level-set advection
+equation \eqref{eq:ls_adeq} with the third-order three-stage SSP-RK method
+\eqref{eq:ssprk33}.  Here an explicit Euler step $\mathcal E(\vct
+u^n,\varphi^n)$ consists of the following steps:
+\begin{enumerate}
+  \item Calculate the curvature and the normal vectors from $\varphi^n$ with
+    one of the methods described in \cref{sec:curvature}.
+  \item Calculate the intermediate velocity field, either $\vct w$
+    \eqref{eq:continuousRightHandVector} or $\vct u^\star$ \eqref{eq:ustar}.
+  \item Solve the Poisson equation \eqref{eq:PoissonDP1} or
+    \eqref{eq:PoissonChorin} for the pressure as described in
+    \cref{sec:pressure-poisson}.
+  \item Correct the velocity field with either \eqref{eq:dp1-update} or
+    \eqref{eq:velcorrection}.
+  \item Advect the level-set function $\varphi^n$ with \eqref{eq:ls_adeq}.
+\end{enumerate}
+
+\section{Time step restriction}
+\label{sec:deltaT}
+We employ the Courant-Friedrich-Lewy~(CFL) condition to allow adaptive time
+stepping and to enforce stability.  The CFL condition that is used in this
+thesis is
+\begin{equation}
+  \Delta t = \frac{C}{\frac{C_c + C_v} 2
+             + \sqrt{(C_c + C_v)^2 + 4C_g^2 + 4C_s^2}},
+\end{equation}
+where the CFL restriction $C<1$, and $C_c$, $C_v$, $C_s$, and $C_g$ represent
+the contributions from the convective term, the viscous stresses, the surface
+tension, and the gravity, respectively,
+\begin{align}
+  C_c &=  \frac{\max_{i,j}|u_{i,j}|}{\Delta x}
+        + \frac{\max_{i,j}|v_{i,j}|}{\Delta y}, \\
+  C_v &= 2\max\left(\frac{\mu_1}{\rho_1},\frac{\mu_2}{\rho_2}\right)
+         \left(\frac{1}{\Delta x^2} + \frac{1}{\Delta y^2}\right), \\
+  C_s &= \sqrt{\frac{\sigma\max_{i,j}|\kappa_{i,j}|}
+                    {\max(\rho_1,\rho_2)\min(\Delta x^2,\Delta y^2)}}, \\
+  C_g &= \sqrt{\frac{|g_x|}{\Delta x} + \frac{|g_y|}{\Delta y}}.
+\end{align}
+This CFL condition is discussed in more detail by~\citet{Lervag08}, and it is
+based on the condition by \citet{Kang00}.
+
+\section{Axisymmetry}
+For axisymmetric flow, the governing equations \eqref{eq:ns1} and
+\eqref{eq:ns2} become
+\begin{equation}
+  \frac 1 r \pd{} r\left(r u\right) + \pd v z = 0,
+\end{equation}
+\begin{multline}
+  \rho\left(\pdt u + u\pd u r + v\pd u z\right) = -\pd p r \\
+    + \mu\left(\frac 1 r \pd{} r\left(r \pd u r\right)
+          + \pdd u z - \frac u {r^2}\right) + \rho f_r + {f_s}_r,
+\end{multline}
+and
+\begin{multline}
+  \rho\left(\pdt v + u\pd v r + v\pd v z\right) = -\pd p z \\
+    + \mu\left(\frac 1 r \pd{} r\left(r \pd v r\right)
+      + \pdd v z\right) + \rho f_z + {f_s}_z.
+\end{multline}
+Here $u$ and $v$ are the radial and axial velocity components, $f_r$ and $f_z$
+are the radial and axial body-force components, and ${f_s}_r$ and ${f_s}_z$ are
+the radial and axial components of the singular surface force, respectively.
+The equations are solved as explained in the previous sections.
+
+\section{Discretization of the curvature and the normal vector}
+\label{sec:curvature}
+As stated in \cref{sec:level-set}, the normal vector \eqref{eq:norm} and the
+curvature \eqref{eq:curv} can be calculated from the level-set function as
+\begin{align*}
+  \vct n &= \frac{\grad\varphi}{|\grad\varphi|}, \\
+  \kappa &= \div\left(\frac{\grad\varphi}{|\grad\varphi|}\right).
+\end{align*}
+They are typically discretized with the standard second-order
+central-difference scheme, cf.\ \cite{Kang00,Sethian03,Xu06}.  The normal
+vector is calculated at the cell edges, and the curvature is calculated at the
+grid nodes.  The curvature is then interpolated to the interface where needed
+with linear interpolation, for instance with
+\begin{equation}
+  \kappa_\Gamma = \frac{|\varphi_{i,j}|\kappa_{i+1,j}
+  + |\varphi_{i+1,k}|\kappa_{i,j}}{|\varphi_{i,j}| + |\varphi_{i+1,j}|}.
+  \label{eq:curvature-gamma}
+\end{equation}
+
+If the level-set method is used to capture non-trivial geometries, then it will
+contain kink regions, that is, areas where the gradient of the level-set
+function is discontinuous.  \Cref{fig:level-set-function} shows a simple
+example of such a kink region for a level-set function in a one-dimensional
+domain that captures two interfaces, one on each side of $x_i$.  The kink at
+$x_i$ may lead to large errors both for the curvature and the normal vector if
+one is not careful.  Errors in the curvature lead to errors in the surface
+tension force and in the pressure, which in turn lead to errors in the
+interface evolution and in the two-phase flow.  Errors in the normal vector
+affect both the calculation of the viscous jump condition and the advection of
+the interface.  If the level-set method is used to study for example
+coalescence and breakup of drops, these errors may severely affect the
+simulations.

+\end{figure}
+
+This problem was to our knowledge first described by \citet{Smereka03}, who
+increase the numerical smoothing in the curvature discretization to lessen the
+effect.  Several non-smearing approaches have subsequently been developed.
+\citet{Macklin05} used the level-set method to study tumor growth, and they
+present a one-sided direction-difference scheme for the discretization of the
+normal vector and the curvature.  Later, \citet{Macklin06} presented an
+improved geometry-aware curvature discretization, where the curvature is
+calculated based on a local least-squares parametrisation of the interface.
+
+A different approach to avoid the kinks was presented by \citet{Salac08}.  They
+used a level-set extraction technique, where an extraction algorithm was used
+to reconstruct separate level-set functions for each distinct \emph{body}.  The
+term \emph{body} is used here to denote a subset of a given phase or fluid.
+For example, in the case of two drops of water colliding in air, the water
+drops would make two distinct bodies.  One can also avoid the extraction
+algorithm altogether by use of multiple marker functions for different bodies,
+see for instance \cite{Coyajee09,Kwakkel12}.  Note, however, that the latter
+approach means that the different bodies will not coalesce unless explicit
+action is made, cf.~\cite{Kwakkel13}.  Also, both of the approaches mentioned
+here fails to handle the problem of kinks from a single body.  That is, there
+may still be kink areas due to deformed bodies, for instance bodies with thin
+filaments or tails, or bodies shaped like horse shoes.
+
+In the following, we first present the direction-difference
+scheme~\cite{Macklin05}.  We then describe the curve-fitting discretization
+method and the local level-set extraction method.
+
+\subsection{Direction-difference scheme}
+\label{sec:dds}
+The direction-difference scheme (DDS) was introduced by \citet{Macklin05}.  It
+uses a quality function to ensure that the difference stencils never cross any
+kink regions.  The DDS is used in Papers A--C to calculate the normal vectors.
+However, in Paper C it is shown that the DDS does not always yield an accurate
+approximation of the normal vector.
+
+The basic strategy is to use a combination of central differences and one-sided
+differences based on the values of a quality function,
+\begin{equation}
+  Q(\vct x) = \left| 1 - |\grad\varphi(\vct x)|\right|.
+  \label{eq:quality}
+\end{equation}
+The quality function is approximated with central differences, and is used to
+detect the areas where the level-set function differs from the signed-distance
+function.  In the following, let $Q_{i,j} \equiv Q(\vct x_{i,j})$ and define
+a parameter $\eta>0$.  This threshold parameter is tuned such that the quality
+function will detect all the kinks.
+
+The quality function is used to define a direction function,
+\begin{equation}
+  \vct D(\vct x_{i,j}) = (D_x(\vct x_{i,j}), D_y(\vct x_{i,j})),
+\end{equation}
+where
+\begin{equation}
+  D_x(\vct x_{i,j}) = \begin{cases}
+    -1 & \text{if $Q_{i-1,j}<\eta$ and $Q_{i+1,j}\geq\eta$,} \\
+     1 & \text{if $Q_{i-1,j}\geq\eta$ and $Q_{i+1,j}<\eta$,} \\
+     0 & \text{if $Q_{i-1,j}<\eta$ and $Q_{i,j}<\eta$ and $Q_{i+1,j}<\eta$,} \\
+     0 & \text{if $Q_{i-1,j}\geq\eta$ and $Q_{i,j}\geq\eta$ and
+         $Q_{i+1,j}\geq\eta$,} \\
+     4 & \text{otherwise.}
+  \end{cases}
+  \label{eq:dirfunc}
+\end{equation}
+$D_y(\vct x_{i,j})$ is defined in a similar manner.  If $D_x(\vct x_{i,j})
++ D_y(\vct x_{i,j}) > 2$, then $\vct D(\vct x_{i,j})$ is chosen as the vector
+normal to $\grad\varphi(\vct x_{i,j})$.  It is normalized, and the sign is
+chosen such that it points in the direction of the best quality.  See
+\cite{Macklin05} for more details.
+
+The DDS is then defined as
+\begin{equation}
+  \partial_x f_{i,j} = \begin{cases}
+    \frac{f_{i,j} - f_{i-1,j}}{\Delta x}    & \text{if $D_x(x_i,y_j) = -1$,} \\
+    \frac{f_{i+1,j} - f_{i,j}}{\Delta x}    & \text{if $D_x(x_i,y_j) =  1$,} \\
+    \frac{f_{i+1,j} - f_{i-1,j}}{2\Delta x} & \text{if $D_x(x_i,y_j) =  0$,}
+  \end{cases}
+  \label{eq:Ddifference}
+\end{equation}
+and similarly for $\partial_y f_{i,j}$, where $f_{i,j}$ is a piecewise smooth
+function.  The DDS is equivalent to using central differences in smooth areas
+and one-sided differences in areas close to the kinks.
+
+\subsection{Curve-fitting discretization method}
+\label{sec:curvature-curve-fitting}
+The curve-fitting discretization method (CFDM) was first presented
+in~\cite{Lervag11} and is based on the method by \citet{Macklin06}.  The main
+idea is to identify kink regions with the quality function \eqref{eq:quality},
+and to use a curve parametrisation of the closest interface to calculate the
+curvature in regions where the quality function is larger than the threshold
+parameter, $\eta$.
+
+The CFDM applied to the curvature or the normal vector at the grid point $\vct
+x_{i,j}$ can be summarized as follows.  See also \cref{fig:cfdm}, which shows
+an example of the CFDM used at $\vct x_{i,j}$.
+\begin{enumerate}
+  \item If the quality of the level-set function in the neighbourhood of $\vct
+    x_{i,j}$ is good, that is
+    \[
+      Q(\vct{x}_{n,m}) \le \eta \; \forall (n,m) \in [i-1,i+1]\times[j-1,j+1],
+    \]
+    then we use a standard discretization.  Otherwise continue to the next
+    step.
+  \item Locate the closest interface, $\Gamma$.
+  \item Find a set of points on the located interface, $\vct x_1, \dots, \vct
+    x_n \in \Gamma$.
+  \item Create a parametrisation $\vct \gamma(s)$ of the points $\vct x_1,
+    \dots, \vct x_n$.
+  \item Use the parametrisation $\vct \gamma(s)$ to calculate a local level-set
+    function.
+  \item Use a standard discretization of the local level-set function to
+    calculate the curvature or the normal vector.
+\end{enumerate}

+\subsection{Local level-set extraction method}
+\label{sec:lolex}
+The local level-set extraction (LOLEX) method is based on the method presented
+by \citet{Salac08}, here called the SLM.  It was found that the latter method
+was insufficient, because it did not treat all the kink problems.  The LOLEX
+method is therefore a further development of the SLM, in that it handles the
+kink regions in a more general manner.
+
+The LOLEX method applied to the curvature or the normal vector at a grid point
+$\vct x_{i,j}$ is summarized by the following algorithm.  The algorithm is
+presented with 2D notation for clarity, and extends easily to 3D.  See also
+\cref{fig:lolex}, which gives a simple example of the procedure.
+\begin{enumerate}
+  \item If the quality in the neighbourhood of $\vct x_{i,j}$ is good, that is
+    \[
+      Q(\vct{x}_{n,m}) \le \eta \; \forall (n,m) \in [i-1,i+1]\times[j-1,j+1],
+    \]
+    then we use a standard discretization.  Otherwise continue to the next
+    step.
+  \item Copy a small, local square centred around $\vct x_{i,j}$ from the
+    level-set function $\varphi$ into a local array $\varphi_\text{loc}$.
+  \item Identify and enumerate all the \emph{bodies} in the local array
+    $\varphi_\text{loc}$.  A \emph{body} is here defined as a set of
+    neighbouring points where $\varphi_\text{loc}<0$, see \cref{fig:lolex}.
+    There will be $n\geq 0$ bodies in any given $\varphi_\text{loc}$ array.
+  \item If no body is identified, that is, if $n=0$, then use a standard
+    discretization with the global level-set function $\varphi$.  Otherwise
+    continue to the next step.
+  \item For each body $n$, extract the relevant parts of $\varphi_\text{loc}$
+    into an array $\varphi_\text{loc}^n$.  If necessary, extrapolate values to
+    ghost cells.
+  \item For each body, $n$, reinitialize $\varphi_\text{loc}^n$.
+  \item At this step, all the bodies in the local grid have their own
+    local level-set functions that have been reinitialized to proper
+    signed-distance functions.  Due to the separation of the bodies, there
+    are no longer any kinks.
+  \item Use the standard discretization of the curvature and the normal
+    vector at the local level-set function that represents the body that is
+    closest to $\vct x_{i,j}$.

+\chapter{The diffuse-domain approach}
+\label{chap:diffuse-domain}
+In the previous chapters, we have considered the modelling of two-phase flows,
+and in particular methods for calculating the curvature and normal vector with
+the level-set method in a reliable manner.  In this chapter, we consider
+a different problem of a more general nature:  How to solve partial
+differential equations (PDEs) in complex domains.  In particular, we consider
+an extension of a diffuse-domain method (DDM) by a high-order correction term
+that gives increased accuracy with respect to interface-width refinements.
+
+We begin with a short introduction to the diffuse-domain approach.  We then
+outline how it can be used to derive a DDM for the steady reaction-diffusion
+equation with Neumann boundary conditions.  Next, we continue with a brief
+introduction to the method of matched asymptotic expansions.  Finally, we
+introduce the high-order correction term derived in Paper~E and show that the
+resulting DDM converge with second order in the diffuse-interface width to the
+original problem.  The analysis also shows that the correction term is not
+necessary for second-order convergence.
+
+\section{Introduction}
+There exist several methods for solving PDEs in complex domains.  Most of them
+have in common that they require tools or methods that are not frequently
+available in standard finite-element or finite-difference software packages.
+Examples of such methods include the immersed-interface method
+\cite{LeVeque94}, the matched interface and boundary method \cite{Zhou06}, the
+extended and composite finite-element method \cite{Dolbow09}, embedded boundary
+methods \cite{Johansen98}, cut-cell methods \cite{Ji06}, and ghost-fluid
+methods \cite{Fedkiw99}.  A different approach, known as the fictitious domain
+method~\cite{Glowinski94,Glowinski96} or the domain imbedding
+method~\cite{Buzbee71}, either augments the original system with equations for
+Lagrange multipliers to enforce the boundary conditions, or use the penalty
+method to enforce the boundary conditions weakly.  For a more complete list of
+references, see Paper~E.
+
+The DDM is an alternative method for solving PDEs in complex domains.  The main
+idea is to use an implicit representation of the boundary, where the sharp
+boundary is replaced by a diffuse layer.  The PDEs are then reformulated on
+a larger, regular domain, and the boundary conditions are incorporated via
+source terms in the diffuse layer.  When the thickness of the diffuse layer is
+reduced, these source terms tend towards singular source terms.  The resulting
+PDEs can then be solved with the use of standard tools and methods.
+
+The diffuse-domain approach was first introduced by \citet{Kockelkoren03} to
+study diffusion inside a cell with homogeneous Neumann boundary conditions at
+the cell boundary.  It was later used by \citet{Li09} to develop a DDM for
+solving PDEs in complex evolving domains with Dirichlet, Neumann and Robin
+boundary conditions, which is hereafter called the DDM1.  The DDM1 has been
+used by \citet{Teigen09-b}, who modelled bulk-surface coupling of material
+quantities on a deformable interface.  It was also used by \citet{Aland10} to
+simulate incompressible two-phase flows in complex domains in 2D and 3D, and by
+\citet{Teigen11} to study two-phase flows with soluble surfactants.
+
+An analysis of the error behaviour of the diffuse-domain approach was done by
+\citet{Franz12} for a diffuse-domain approximation of an elliptic problem with
+Dirichlet boundary conditions.  They considered the infinity norm of the
+difference of the approximated solution and the exact solution, and their
+analysis shows that the approximation quality is of order one in the interface
+width.
+
+In Paper~E, we present the DDM2, which is an extension of the DDM1 by
+a high-order correction term.  The DDM2 is derived for elliptic problems with
+Neumann and Robin boundary conditions, and it is shown to be asymptotically
+second-order accurate in the interface width.  However, the analysis in Paper~E
+is somewhat lacking in that it assumes that the DDM1 is only first-order
+accurate.  In the following sections, we extend the analysis of Paper~E and
+show that the DDM1 is also second-order accurate.  The analysis is shown for
+the steady reaction-diffusion equation with Neumann boundary conditions, but
+the same technique also applies for the corresponding Robin problem.
+
+\section{The DDM for a Neumann problem}
+Consider the steady reaction-diffusion equation with Neumann boundary
+conditions,
+\begin{equation}
+  \begin{alignedat}{2}
+    \lapl u - u  &= f        & \txin D, \\
+    \ndot\grad u &= g \qquad & \txon \partial D,
+  \end{alignedat}
+  \label{eq:ddan}
+\end{equation}
+where $f$ and $g$ are given.  Let $\chi_D$ be the characteristic function of
+$D$,
+\begin{equation}
+  \chi_D = \begin{cases}
+    1 & \text{if $x\in D$,} \\
+    0 & \text{if $x\notin D$.}
+  \end{cases}
+\end{equation}
+The main idea with the diffuse-domain approach is to extend the original
+equation \eqref{eq:ddan} into a larger and regular domain $\Omega\supset D$, as
+depicted in \cref{fig:ddadomain}.  The extension can be written as
+\begin{equation}
+  \div(\chi_D\grad u) - \chi_D u + \text{BC} = \chi_D f,
+  \label{eq:ddm}
+\end{equation}
+where BC is a singular source term that represents the physical boundary
+condition on $\partial\Omega$.

+  \caption{A regular domain $\Omega$ that contains a complex domain $D$.}
+  \label{fig:ddadomain}
+\end{figure}
+
+The characteristic function is typically approximated by the phase-field
+function,
+\begin{equation}
+  \chi_D \simeq \phi(\vct x,t) = \frac{1}{2} \left( 1
+  - \tanh \left( \frac{3r(\vct x,t)}{\epsilon} \right) \right),
+  \label{eq:characteristic}
+\end{equation}
+where $\epsilon$ is the interface width and $r(\vct x,t)$ is the
+signed-distance function with respect to the boundary $\partial D$, which is
+taken to be negative inside $D$.
+
+The main difficulty with the diffuse-domain approach is the derivation of
+approximations for the boundary condition term BC.  \citet{Li09} give four
+approximations that are shown to converge asymptotically with first order in
+$\epsilon$ to the original equation when $\epsilon$ is decreased.  In the
+following we consider the approximation
+\begin{equation}
+  \text{BC} \simeq |\grad\phi| g.
+  \label{eq:bc1}
+\end{equation}
+If we combine the above approximations \eqref{eq:characteristic} and
+\eqref{eq:bc1}, we get a DDM1 equation for \eqref{eq:ddan},
+\begin{equation}
+  \div\left(\phi\grad u\right) - \phi u +  |\grad\phi| g = \phi f.
+  \label{eq:ddm1}
+\end{equation}
+
+\section{The method of matched asymptotic expansions}
+The following is a brief introduction to the method of matched asymptotic
+expansions, which is used to show that a given diffuse-domain approximation
+converges to the original problem when the interface width is decreased.  More
+details can be found in Paper~E and in \cite{Pego88}.
+
+Let $u$ be some diffuse-domain variable.  The asymptotic convergence of a given
+diffuse-domain approximation can be shown through expansions of the
+diffuse-domain variables in powers of the interface thickness $\epsilon$ in
+regions close to and far from the interface.  For example, the expansions of
+$u$ are
+\begin{align}
+  u(\vct x)        &= \sum_{k=0}^\infty \epsilon^k      u^{(k)}(\vct x), \\
+  \hat u(z,\vct s) &= \sum_{k=0}^\infty \epsilon^k \hat u^{(k)}(z,\vct s),
+\end{align}
+where $u(\vct x)$ and $\hat u(\vct s,z)$ denote the outer and inner expansions,
+respectively.  Here $z$ is a stretched variable,
+\begin{equation}
+  z = \frac{r(\vct x)}{\epsilon},
+\end{equation}
+where $r$ is the signed distance from the point $\vct x$ to $\partial D$ and is
+taken to be negative inside $D$.  Further, $z$ and $\vct s$ form a local
+coordinate system such that
+\begin{equation}
+  \vct x(\vct s,z) = \vct X(\vct s) + \epsilon z\vct n(\vct s),
+\end{equation}
+where $\vct X(\vct s)$ is a parametrisation of the interface, $\vct n(\vct s)$
+is the interface normal vector, and $z$ is a stretched variable.
+
+When the inner and outer expansions are found, they are matched in a region
+where both solutions are valid and where $\epsilon z = \bigo 1$, see
+\cref{fig:regions}.  The outer solution is then evaluated in the inner
+coordinates, which leads to a set of matching conditions that must hold when
+$\epsilon\to 0$.  If we consider $\epsilon$ to be fixed and let $z \to
+\pm\infty$, we get the following asymptotic matching conditions:
+\begin{equation}
+  \label{eq:match1}
+  \zlimpm \hat u^{(0)}(z,\vct s) = u^{(0)}(\vct s),
+\end{equation}
+and as $z \to \pm\infty$,
+\begin{align}
+  \label{eq:match2}
+  \hat u^{(1)}(z,\vct s) &= u^{(1)}(\vct s)
+    + z\ndot\grad u^{(0)}(\vct s) + \smallo 1, \\
+  \begin{split}
+    \hat u^{(2)}(z,\vct s) &= u^{(2)}(\vct s)
+      + z\ndot\grad u^{(1)}(\vct s) \\
+      &\quad + \frac{z^2}{2} (\ndot\grad)\grad u^{(0)}(\vct s)\cdot\vct n
+      + \smallo 1.
+    \label{eq:match3}

+\end{figure}
+
+We remark that the inner expansion is used to obtain the boundary condition on
+$\partial D$, and that the outer solution is used to obtain the sharp-interface
+equation inside the physical domain $D$.
+
+To show that a given DDM approximation converges with second order, one must
+show that the order-one term of the outer solution of the DDM equation is zero
+in $D$.  As an example, we consider the outer solution of the DDM1 equation
+\eqref{eq:ddm1}, which is
+\begin{equation}
+  \begin{split}
+    \lapl u^{(0)} - u^{(0)} &= f, \\
+    \lapl u^{(1)} - u^{(1)} &= 0, \\
+    \lapl u^{(k)} - u^{(k)} &= 0,\qquad k = 2,3,\dots.
+  \end{split}
+  \label{eq:ddm_outer}
+\end{equation}
+For the solution to be asymptotically second order, that is $u = u^{(0)}
++ \bigo{\epsilon^2}$, we must have that $u^{(0)}$ satisfies the original
+problem \eqref{eq:ddan} and that $u^{(1)}=0$.  Thus the inner expansion must
+yield a boundary condition for $u^{(1)}$ to enforce $u^{(1)}=0$.
+
+\section{Asymptotic analysis of the DDM1 and the DDM2}
+\label{sec:DDM2}
+In Paper~E we present the DDM2, which extends the DDM1 \eqref{eq:ddm1} with
+a high-order correction term,
+\begin{equation}
+  \div\left(\phi\grad u\right) - \phi u +  |\grad\phi| g
+    + r|\grad\phi|\left(f - \kappa  g - \lapls u + u\right) = \phi f.
+  \label{eq:ddm2}
+\end{equation}
+Here $r|\grad\phi|\left(f - \kappa  g - \lapls u + u\right)$ is the
+correction term, $\kappa$ is the curvature of the boundary $\partial D$, and
+$\lapls u$ is the surface Laplacian of $u$, which can be defined as
+\begin{equation}
+  \lapls u \equiv
+  \left( I - \vct n\otimes\vct n \right)
+        \div \left( I - \vct n\otimes\vct n \right)\grad u,
+\end{equation}
+where $I$ is the identity matrix and $\vct n$ is the normal vector.  The
+curvature can be calculated from the phase-field function
+\eqref{eq:characteristic} as
+\begin{equation}
+  \kappa = -\div\frac{\grad\phi}{|\grad\phi|}.
+\end{equation}
+
+In the following, we use the method of matched asymptotic expansions to show
+that the DDM1 \eqref{eq:ddm1} and the DDM2 \eqref{eq:ddm2} are both
+second-order approximations of \eqref{eq:ddan} in $\epsilon$.  First, it is
+easy to see that the outer expansions of both approximations are given by
+\eqref{eq:ddm_outer}.
+
+Next, we consider the inner expansion of the DDM2 \eqref{eq:ddm2}, which is
+\begin{multline}
+  \frac{1}{\epsilon^2}\left(\phi\hat u_z\right)_z
+  + \frac \kappa \epsilon \phi\hat u_z
+  + \phi\lapls \hat u
+  - \phi\hat u \\
+  - \frac 1 \epsilon \phi_z g
+  - z\phi_z\left(\hat u + \hat f - \kappa g - \lapls\hat u\right)
+  = \phi \hat f.
+  \label{eq:ddm_inner}
+\end{multline}
+We expand $\hat u(z,\vct s)$ in powers of $\epsilon$ and collect the lowest
+order terms,
+\begin{equation}
+  \left(\phi\hat u_z^{(0)}\right)_z = 0.
+\end{equation}
+If we integrate over all $z$, we get that $\hat u_z^{(0)} = 0$.  The next order
+terms of~\eqref{eq:ddm_inner} then give
+\begin{equation}
+  \left(\phi\hat u_z^{(1)}\right)_z = \phi_z g,
+\end{equation}
+and again we integrate, which gives that
+\begin{equation}
+  \phi\hat u_z^{(1)} = \phi g + C
+  \label{eq:uz1}
+\end{equation}
+where the constant $C$ must be zero, since $\lim_{z\to\infty}\phi(z) = 0$.  Now
+consider the limit $z\to-\infty$ and use the matching condition
+\eqref{eq:match2} to get
+\begin{equation}
+  \ndot\grad u^{(0)} = g.
+\end{equation}
+Thus $u^{(0)}$ satisfies the original problem at least to first order in
+$\epsilon$.  This shows that both DDM1 and DDM2 are first-order approximations
+of the sharp-interface problem.
+
+To obtain the result for the next order, we need to apply the derivative of
+the matching condition \eqref{eq:match3},
+\begin{equation}
+  \hat u_z^{(2)} = \ndot\grad u^{(1)}
+      + z (\ndot\grad)\grad u^{(0)}\cdot\vct n.
+  \label{eq:match3_z}
+\end{equation}
+Further, we use that $u^{(0)}$ satisfies
+\begin{equation}
+  \lapl u^{(0)} - u^{(0)} = f^{(0)},
+\end{equation}
+and that the Laplacian may be decomposed as
+\begin{equation}
+  \lapl u = (\ndot\grad)\grad u\cdot\vct n + \kappa\ndot\grad u + \lapls u,
+\end{equation}
+to get
+\begin{equation}
+  (\ndot\grad)\grad u^{(0)}\cdot\vct n
+    = u^{(0)} + f^{(0)} - \kappa g - \lapls u^{(0)}.
+  \label{eq:ngradun}
+\end{equation}
+Now insert \eqref{eq:ngradun} into \eqref{eq:match3_z} and use the matching
+condition \eqref{eq:match1} to obtain a modified matching condition,
+\begin{equation}
+  \hat u_z^{(2)} - z\left(\hat u^{(0)} + \hat f^{(0)}
+        - \kappa g - \lapls \hat u^{(0)}\right)
+  = \ndot\grad u^{(1)}.
+  \label{eq:match3_z2}
+\end{equation}
+
+We are now ready to consider the zeroth order terms,
+\begin{multline}
+  \label{eq:o1}
+  \left(\phi\hat u^{(2)}_z\right)_z
+  + \phi\kappa\hat u_z^{(1)}
+  + \phi\lapls \hat u^{(0)}
+  - \phi\hat u^{(0)} \\
+  - z\phi_z\left(\hat u^{(0)}
+      + \hat f^{(0)} - \kappa g - \lapls\hat u^{(0)}\right)
+  = \phi \hat f^{(0)}.
+\end{multline}
+The modified matching condition \eqref{eq:match3_z2} motivates that we subtract
+and add the term
+\[
+  \bigg(z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\bigg)_z
+\]
+to \eqref{eq:o1}, which gives
+\begin{multline}
+  \bigg(\phi\hat u_z^{(2)}
+    - z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\bigg)_z \\
+  + \bigg(z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\bigg)_z \\
+  + \phi\kappa\hat u_z^{(1)}
+  + \phi\lapls \hat u^{(0)}
+  - \phi\hat u^{(0)} \\
+  - z\phi_z\left(\hat u^{(0)}
+      + \hat f^{(0)} - \kappa g - \lapls\hat u^{(0)}\right)
+  = \phi \hat f^{(0)}.
+\end{multline}
+We expand the terms and use \eqref{eq:uz1},
+\begin{multline}
+  \bigg(\phi\hat u_z^{(2)}
+    - z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\bigg)_z \\
+  + \cancel{\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g

+  + \cancel{\phi\kappa g
+  + \phi\lapls \hat u^{(0)}
+  - \phi\hat u^{(0)}}
+  = \cancel{\phi \hat f^{(0)}},
+  \label{eq:o2}
+\end{multline}
+or
+\begin{multline}
+  \bigg(\phi\hat u_z^{(2)}
+    - z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\bigg)_z \\
+  + z\phi\left(\cancel{\hat u_z^{(0)}} + \hat f_z^{(0)}
+      - \cancel{(\kappa g)_z}
+      - \cancel{\lapls \hat u_z^{(0)}}\right) = 0.
+\end{multline}
+If we assume that $\hat f_z^{(0)}$, we get
+\begin{equation}
+  \bigg(\phi\hat u_z^{(2)}
+    - z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\bigg)_z = 0.
+  \label{eq:o3}
+\end{equation}
+Finally, we integrate the left-hand side and take the limit,
+\begin{align}
+  \nonumber
+  \eint{\bigg(\phi\hat u_z^{(2)}
+    &- z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+     - \lapls \hat u^{(0)}\right)\bigg)_z} \\
+  \nonumber
+  &= \ejmp{\phi\hat u_z^{(2)}
+    - z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)} \\
+  \nonumber
+  &= -\zlimm{\left(\hat u_z^{(2)}
+    - z\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\right)} \\
+  &= -\ndot\grad u^{(1)},
+\end{align}
+thus
+\begin{equation}
+  \ndot\grad u^{(1)} = 0.
+  \label{eq:ngradu1}
+\end{equation}
+Combined with \eqref{eq:ddm_outer}, this shows that $u^{(1)}=0$, and so DDM2
+converges asymptotically with second order to the original problem.
+
+The analysis above also holds for DDM1, except instead of \eqref{eq:o3} we get
+\begin{multline}
+  \bigg(\phi\hat u_z^{(2)}
+    - z\phi\left(\hat u^{(0)} + \hat f^{(0)} - \kappa g
+    - \lapls \hat u^{(0)}\right)\bigg)_z \\
+  = - z\phi_z \left(\hat u^{(0)} + \hat
+        f^{(0)} - \kappa g - \lapls \hat u^{(0)}\right)
+  = - z\phi_z D,
+  \label{eq:o4}
+\end{multline}
+where $D$ is independent of $z$.  Now we use that
+\begin{equation}
+  \phi_z = -(3 \sech^2 3z)/2,
+\end{equation}
+which follows from the definition of the phase-field function
+\eqref{eq:characteristic}.  We integrate the right-hand side, which gives
+\begin{equation}
+  D\eint{z\phi_z} = -D\frac 3 2\eint{z\sech^2 3z} = 0.
+\end{equation}
+Thus DDM1 is also second order in $\epsilon$.
+
+The difference between the DDM1 and the DDM2 is therefore that the correction
+term with the DDM2 directly cancels the term on the right-hand side in
+\eqref{eq:o4}.  This should give an increase of accuracy, but the convergence
+order remains the same.
+
+The analysis for the corresponding Robin problem is essentially the same as the
+above.  In Paper~E, the DDM1 and DDM2 are compared for several elliptic
+problems with both Neumann and Robin boundary conditions.  The results of
+Paper~E show that the correction term in the DDM2 leads to an increase of
+accuracy and that both DDM1 and DDM2 converge with second-order accuracy.
+
+\section{Summary}
+In this chapter, we have given a brief introduction to the diffuse-domain
+method (DDM).  We considered a steady reaction-diffusion equation with Neumann
+boundary conditions \eqref{eq:ddan} and two DDM approximations:  DDM1
+\eqref{eq:ddm1} and DDM2 \eqref{eq:ddm2}.  The DDM2 is an extension of DDM1 by
+a high-order correction term, and was first derived in Paper~E.
+
+Next, we gave an outline of the method of matched asymptotic expansions, and we
+used it to show that both the DDM1 and the DDM2 converged asymptotically with
+second order in the diffuse-interface width to the original equation
+\eqref{eq:ddan}.  The analysis shows that the correction term in the DDM2 leads
+to a cancellation in the asymptotic expansions.  By doing the integration, we
+see that this cancellation is not necessary for obtaining the second order
+convergence.

+\section[Paper A]{Paper A:  Calculation of interface curvature with the
+  level-set method}
+Karl Yngve Lervåg.  Published in \emph{MekIT'11 - 6th National Conference on
+  Computational Mechanics, Trondheim}, 2011.  ISBN: 978-82-519-2798-7.
+
+In this paper I address a problem with the calculation of the interface
+curvature with the level-set method, cf.\ \cref{sec:curvature}.  The curvature
+can be calculated from the level-set function, $\phi$, as
+\begin{equation}
+  \kappa = \div\vct n = \div\frac{\grad\phi}{|\grad\phi|}.
+\end{equation}
+It is typically discretized by standard methods such as the second-order
+central-difference scheme (CD-2), and interpolated to the interface where
+needed \cite{Osher88,Kang00,Osher03}.  However, the level-set function as
+a signed-distance function will tend to have kinks where its gradient is
+discontinuous.  The standard methods may lead to large errors in the curvature
+close to these regions, which in turn may lead to errors in the surface tension
+force.
+
+The main contribution of this paper is a new curve-fitting discretization
+method (CFDM) for the curvature (see \cref{sec:curvature-curve-fitting}).  The
+method is based on the approach developed by \citet{Macklin06}.  It differs in
+that it uses a cubic Hermite spline parametrisation of the interface, and that
+the curvature values are calculated on the grid and then interpolated to the
+interface as opposed to using a localised grid centred at the interface as in
+\cite{Macklin06}.

+    close to two interfaces.}

+\end{figure}
+
+The CFDM is tested and compared with the CD-2 for two test cases, and it is
+shown to yield better results in both cases.  \Cref{fig:A1} shows one of these
+results, where the calculated curvature values are compared.  In the example,
+a cylindrical drop impacts on a liquid film.  The figure shows that the CD-2
+leads to large errors in the curvature calculations in the kink regions, that
+is, the red and dark blue regions in \cref{fig:A1a} near the liquid film.
+These errors are not present with the new method, cf.\ \cref{fig:A1b}.
+
+\paragraph{My contribution:}  I developed the method and implemented it into

+\cref{sec:deltaT,sec:t-discr,sec:x-discr,sec:projection-method,sec:curvature}.

+\section[Paper B]{Paper B:  Curvature calculations for the level-set method}
+Karl Yngve Lervåg and Åsmund Ervik.  Published in \emph{ENUMATH 2011}
+proceedings volume, Springer, 2013.  ISBN: 978-3642331336.
+
+This paper is a continuation of Paper A.  The main contribution in this paper
+is a comparison of different methods for calculating the curvature in a robust
+manner with the level-set method in the kink regions.  In particular, the
+CFDM\footnote{The method is called LM in the paper.  Here CFDM is used, in
+  order to be consistent with the rest of the thesis.} that was presented in
+Paper A is compared with Macklin and Lowengrub's method (MLM)~\cite{Macklin06}.
+In addition, the method is compared with the second-order central-difference
+scheme (CD-2) and the more recent method presented by \citet{Salac08}, here
+called Salac and Lu's method (SLM).
+
+The main result in the paper is shown in \cref{fig:B1}, which shows
+a comparison of the methods for a case where two drops collide in a 2D shear
+flow.  In particular, it shows snapshots of the evolution of the interfaces and
+the curvature at times $t=\SI{2.30}{s}$, $t=\SI{2.75}{s}$, and
+$t=\SI{3.10}{s}$.  The results show that all of the improved methods, that is
+MLM, CFDM, and SLM, handle the kink region in a more reliable manner than CD-2.
+The reason that the result with MLM differs from those with CFDM and SLM might
+be that it uses a localised grid centred at the interface to calculate the
+curvature, which means that it does not need to use interpolation of the
+curvature from the grid to the interface.  Note that the difference is mainly
+that the MLM results in slightly earlier coalescence in the given case.

+\section[Paper C]{Paper C:  Calculation of the interface curvature and normal
+  vector with the level-set method}
+Karl Yngve Lervåg, Bernhard Müller, and Svend Tollak Munkejord.  Published in
+Computers and Fluids, volume 84 (2013), 218--230.
+
+Paper A presented the curve-fitting discretization method (CFDM) for the
+calculation of the curvature with the level-set method.  The method was
+designed to be robust in the calculation of the curvature in kink regions, that
+is regions where the gradient of the level-set function is not smooth.  This
+paper presents the details of the CFDM and applies it to the calculation of
+both the curvature and the normal vector.
+
+In the paper we compare the CFDM with the second-order central-difference
+scheme (CD-2) for several test cases.  In the first case, we consider the
+curvature calculations for a nontrivial geometry that includes some kink
+regions.  This is a static test case with no flow, and the results show that
+the CD-2 leads to large errors for the curvature calculations in areas close to
+kink regions and that these errors are not present with the CFDM.
+
+In the following two cases, we consider the collision of two drops in a 2D
+shear flow and in an axisymmetric flow.  These cases show that the errors in
+the curvature calculations in the kink regions with the CD-2 lead to errors in
+the pressure that prevents coalescence.  These errors are prevented with the
+CFDM.  The curvature and the evolution of the interfaces for the axisymmetric
+case are shown in \cref{fig:C1,fig:C2}.  As in the earlier results of Papers
+A and B, the figures show that the errors in the curvature calculation with
+CD-2 prevent coalescence, in this case leading to a slower coalescence process.

+\section[Paper D]{Paper D:  A robust method for calculating interface curvature
+  and normal vectors using an extracted local level set}
+Åsmund Ervik, Karl Yngve Lervåg, and Svend Tollak Munkejord.  Submitted to
+Journal of Computational Physics, 2013.
+
+In this paper we present an alternative method for the calculation of the
+curvature and the normal vector of an interface with the level-set method in
+kink regions, hereafter called the local level-set extraction (LOLEX) method.
+The method is based on a method presented by \citet{Salac08} (SLM), who handle
+the kink region by extracting different bodies of a domain into separate
+level-set functions.  This procedure removes most of the kink regions, but it
+does not handle kink regions that are due to complex interfaces of single
+bodies.  Our method extends the SLM by making it local.  That is, we only
+consider the local area around the point for which we are calculating the
+curvature or the normal vector.  This leads to a method that is more generally
+applicable, as shown in \cref{fig:D1}.  The figure shows a comparison between
+the LOLEX method, the SLM, and the standard central differences (CD-2).  CD-2
+leads to curvature spikes at the kink regions, as explained in
+\cref{sec:curvature}.  The SLM gives a better result for the kink regions
+around the rightmost disc.  However, since the other two discs are connected to
+each other and to the film, they are considered to be the same body and are
+extracted into the same level-set function.  Several kink regions are therefore
+not removed.  Since the LOLEX method only considers the local area, as
+explained in \cref{sec:lolex}, it is able to handle all the kink regions in
+a robust manner.

+    negative and red is positive.}
+  \label{fig:D1}
+\end{figure}
+
+The LOLEX method has proven to be a good alternative to the CFDM presented in
+Paper A.  Its main advantages are that it does not rely on complex algorithms
+as used in the CFDM or by \citet{Macklin06}, and that the method easily extends
+to 3D as demonstrated in the paper in Section~4.4.
+
+In the previous papers A--C, we used the DP1 projection method by
+\citet{Hansen05}.  In this paper we instead used the more standard Chorin
+projection method.  These methods differ in that the DP1 assumes
+\begin{equation}
+  \div\left(\pdt{\vct u}\right) = 0.
+\end{equation}
+When compared with the Chorin method, this assumption becomes equivalent to
+assuming that $\div\vct u^{n} = 0$ in \eqref{eq:PoissonChorin}.  That is, the
+DP1 assumes that the initial velocity field is divergence free.  We have found
+that the DP1 works well in most cases, but that it is less robust than the
+Chorin method.  In particular, the Chorin method is not equally affected by
+errors in the curvature calculations in kink regions.  In other words, the
+difference between using a standard discretization and an improved
+discretization of the curvature is smaller with the Chorin method than with the
+DP1.
+
+The LOLEX method is used for several test cases and compared with CD-2.  The
+results indicate that even though we use the Chorin projection method, the
+LOLEX method outperforms CD-2 in all cases.  Further, the results agree well
+with experiments, except for time instants, as shown in \cref{fig:D2}.  The
+exact reason why the time instants do not match is not known, but one reason
+may be that the initial condition of the numerical simulation did not match the
+corresponding state of the experiment.

+    from~\cite{Zhao11}, Copyright (2011), with permission from Elsevier.}
+  \label{fig:D2}
+\end{figure}
+
+When we study the drop-film collision processes, an important consequence of
+the error in the curvature calculation is a loss of kinetic energy.  This can
+be seen in \cref{fig:D3}, which compares the LOLEX method with CD-2 at two
+different stages of the collision process.  The figure also compares two
+different frequencies of reinitialization of the level-set function:  Every
+7 time steps ((a) and (c)) and every single time step ((b) and (d)).  The
+figure shows that the error in the curvature calculation with CD-2 leads to
+a shorter neck, as seen in \cref{fig:D3}, (c) and (d).  The error is larger for
+the higher frequency of reinitialization.  The results indicate that CD-2 leads
+to a loss of kinetic energy during the collision process when compared with the
+LOLEX method.  The LOLEX method is not significantly affected by the amount of
+reinitialization, and the kink region does not affect the curvature
+calculation, cf.\ \cref{sec:lolex}.  Thus the pressure field is more sensible,
+as seen in \cref{fig:D3} (a) and (b).  Finally, we remark that some authors
+have noted \cite{Blanchette06} that the height of the neck and the dynamics of
+the capillary waves are important factors for the partial coalescence
+mechanism, which implies that the correct calculation of the curvature is
+important to capture the correct physical behavior.

+\section[Paper E]{Paper E:  Towards a second-order diffuse-domain approach for
+  solving PDEs in complex geometries}
+Karl Yngve Lervåg and John Lowengrub.  Submitted to Communications in Math.
+Sciences, 2013.
+
+\citet{Li09} developed a diffuse-domain method for solving partial-differential
+equations (PDEs) inside complex, dynamic geometries with Dirichlet, Neumann,
+and Robin boundary conditions.  This method is in the following referred to as
+DDM1.  They use the diffuse-domain approach~\cite{Kockelkoren03}, where the
+geometry is represented implicitly and the sharp boundary is replaced by
+a diffuse layer with a fixed interface width.  The original governing equations
+are then reformulated on a larger, regular domain and the boundary conditions
+are incorporated via singular source terms.  The method of matched asymptotic
+expansions is used to show that the reformulated problem converges
+asymptotically to the original problem.
+
+In the present paper, we use the method of matched asymptotic expansions to
+extend the DDM1 with include a high-order correction term in the diffuse
+formulation, cf.\ \cref{sec:DDM2}.  The extension is derived for elliptic
+problems with Neumann and Robin boundary conditions, where the correction term
+is shown to yield an asymptotically second-order accurate approximation of the
+original problem.  The new method is referred to as the DDM2.
+
+The DDM1 and DDM2 are compared for a selection of test problems.  The resulting
+equations were discretized by standard second-order central-difference schemes
+on uniform grids, and solved by a multigrid method.  A red-black Gauss-Seidel
+type iterative method was used as a smoother, see \cite{Wise07}.
+
+In addition to the comparison of DDM1 and DDM2, we compared two different
+approximations of the boundary conditions.  These correspond to different
+diffuse-interface surface delta functions, and for the Neumann boundary
+conditions they are
+\begin{equation}
+  \text{BC1} = |\grad\phi| g,
+\end{equation}
+and
+\begin{equation}
+  \text{BC2} = \epsilon|\grad\phi|^2 g.
+\end{equation}
+The approximations are similar for the Robin boundary condition, although here
+it was found that only BC1 resulted in a valid asymptotically second-order
+accurate DDM2.
+
+Our results show that the global accuracy and convergence of DDM2 is better
+than DDM1, however both methods perform well and the global convergence rate is
+around two for each.  The error was measured as the L$_2$ norm of the
+difference between an analytic solution and the solution $u_\epsilon$ for
+a given interface width, $\epsilon$.
+
+\Cref{fig:E1,fig:E2} show two of the results, the first one with the Neumann
+boundary conditions and the second with the Robin boundary condition.  The
+results indicate that DDM2 performs slightly better than DDM1.  They also show
+that the approximation BC1 gives more accurate results than BC2.  In
+particular, we found that with BC2 we needed much finer grids to obtain
+convergence for a given $\epsilon$.  For the smallest values of $\epsilon$ we
+were not able to refine the grids enough to obtain valid results.

+\chapter{Conclusions and outlook}
+\label{chap:conclusions}
+This thesis has considered two different problems:  The discretization of
+interface curvature and normal vectors with the level-set method and
+a diffuse-domain approach for solving partial-differential equations (PDEs) in
+complex domains.  In the following, some general concluding remarks and
+recommendations for further work are given.
+
+\section*{Conclusions}
+The first part of the thesis considered the modelling of incompressible
+two-phase flow.  The main motivation was to study two-phase flow phenomena that
+are relevant for compact heat exchangers, such as drop-drop and drop-film
+collisions.  In particular, the thesis addressed a challenge with the
+calculation of interface curvature and normal vectors with the level-set
+method.  Two methods were presented to handle the discretization in the kink
+regions: A curve-fitting discretization method (CFDM) and a local level-set
+extraction (LOLEX) method.  Both methods were shown to be robust in the kink
+regions, where the standard central-difference scheme (CD-2) fails.  Of these
+methods, the LOLEX method is the preferred method, because it relies on a less
+complicated algorithm that easily extends to 3D.
+
+CD-2 and the LOLEX method were used for simulations of drop-film collisions
+that were compared with experiments.  The results showed that CD-2 leads to
+errors in the curvature that cause unphysical pressure spikes during the
+coalescence.  The errors are shown to lead to a dissipation of kinetic energy
+during the collision and to a slower coalescence process.  The LOLEX method was
+shown to prevent these unphysical pressure spikes, and to produce to more
+accurate results.
+
+The second part of the thesis considered the diffuse-domain approach for
+solving PDEs in complex domains.  The main contribution, presented in Paper~E,
+was the derivation of an asymptotically second-order diffuse-domain method
+(DDM2) for solving elliptic problems in complex geometries with Neumann and
+Robin boundary conditions.  The new method is an extension by a high-order
+correction term of the method presented in \cite{Li09}, here called DDM1.  The
+DDM1 and DDM2 were compared, and the results indicated that the DDM2 was
+slightly better than the DDM1.
+
+The thesis has expanded on the results of Paper~E with a new asymptotic
+analysis that shows that DDM1 is in fact also asymptotically second order.
+This analysis helps to explain why the performance of DDM2 presented in Paper~E
+is only slightly better than that of DDM1.  As such, the new analysis leads to
+a better understanding of the DDM1 and the DDM2.
+
+\section*{Outlook}
+The following gives an outline of some possibilities for future work.
+\begin{itemize}
+  \item A natural continuation of this work is to perform more in-depth
+    comparisons of simulations with experiments for the drop-film collision
+    phenomenon that was started in Paper~D.  In addition, it would be
+    interesting to study other two-phase flow phenomena that are relevant for
+    heat-exchanger processes, for instance drop-drop collisions or flow across
+    tube bundles.  The latter requires the treatment of more complex boundaries,
+    which can be handled either with the diffuse-domain method or other methods
+    from the literature.
+  \item Paper~C gave a short comparison of the standard discretization method
+    (CD-2), the direction-difference scheme (DDS), and the curve-fitting
+    discretization scheme (CFDM) applied to the calculation of the normal
+    vectors.  The results showed that the CD-2 leads to inaccurate results in
+    the kink regions.  The DDS gives robust and accurate results in most cases,
+    but an example is given where only the CFDM yields an accurate result.
+    However, the impact of inaccurate calculations of the normal vector should
+    be investigated in more detail.  The normal vector is used both for the
+    solution of the level-set equations \eqref{eq:ls_adeq},
+    \eqref{eq:ls_velextr}, and \eqref{eq:ls_reinit}, and for the calculation of
+    the interface jumps \eqref{eq:jump_pressure} and \eqref{eq:jumptens}, so
+    one can expect that large errors in the calculation of the normal vector
+    may lead to large errors in the numerical solution.  This warrants
+    a further study.
+  \item Mass and heat transfer are obviously an important part of the
+    heat-exchanger processes.  The models that have been used in this thesis
+    should therefore be expanded with additional models for heat transfer and
+    mass transfer to enable the simulation of more relevant phenomena.
+  \item The DDM2 was only derived for problems with Robin and Neumann boundary
+    conditions.  If possible, it should be extended to also work with Dirichlet
+    boundary conditions.
+  \item As explained in Paper~E, we found that we were unable to solve the
+    discrete system of equations when the surface Laplacian part of the
+    correction term for the DDM2 was included.  A further investigation of this
+    problem should be done, and stable numerical methods to solve the full DDM2
+    equations should be developed.
+  \item The diffuse-domain approach is a promising method for solving problems
+    in complex and confined geometries with standard tools and methods.
+    \citet{Aland10} provide a diffuse-domain formulation of the Navier-Stokes
+    Cahn-Hilliard equations for incompressible two-phase flow and use it to
+    compute two-phase flow in both complex and confined geometries.  However,
+    they do not provide an asymptotic analysis of the reformulated equations to
+    show that the system converges.  Such an analysis would be interesting, in
+    particular to verify that the equations do converge to the original problem
+    when the interface width is decreased.
+  \item Finally, it would be interesting to develop a second-order
+    diffuse-domain formulation for the incompressible Navier-Stokes equations.
+    A starting point would be to use the results and techniques from this
+    thesis and Paper~E.
