FreeFem++可以生成高质量的有限元网格。可以用于流体力学

%Click on ``Install or Update now''\\
%A window appears. \\
%Click on ``Open'' then ``Next'' and then choose ``Install from Internet''\\
%Click on ``Next'' twice and choose ``Direct Connection''.\\
%Then choose one of the download sites.\\
%For instance : ftp://ftp-stud.fht-esslingen.de\\
%Then choose in each category the options to install. \\
%(click on the symbol + for each, you can then see the options appear)\\
%\\
%Here are the required options for FreeFem++ and TCL TK to work :\\
%+ all options of ``Devel'' (it includes gcc ...etc...)\\
%+ all options of ``Graphics'' (specially ``Gnuplot'' to be able \\
%to see the results of FreeFem++ on a graphic)\\
%+ all options of X11 and XFree86 \\
%\\
%You can install ``Xemacs'' and others editors in the category ``Editors''.\\
%\\
%Then click on ``Next'' and wait that Cygwin is installed.\\
%Then an ic鬾e appears on yours Desktop.\\
%Click on it and the Cygwin window is opened. It is like an Unix terminal.\\
%\\
%To work on a terminal X type : \\
%-$>$ startX\\
%You will have to work on a terminal X to have Gnuplot and visualize \\
%the results of FreeFem++ scripts)\\
%\\
%Now you have to compile and install FreeFem++.\\
%\\
%\subsubsection{Compilation and Installation of FreeFem++ under Cygwin}
%go to the site :\\
%http://www.freefem.org\\
%click on FreeFem++\\
%and download FreeFem++ (the version when I wrote this is 1.38)\\
%Choose to download in your cygwin/home/you directory.\\
%\\
%Then on your terminal Cygwin type :\\
%-$>$ tar zxvf freefem++.tgz\\
%to uncompress this file.\\
%\\
%Go into FreeFem++v1.38 directory by typing:\\
%-$>$ cd FreeFem++v1.38\\
%\\
%Now you have to compile FreeFem++.\\
%type:\\
%-$>$ make all HOSTTYPE=i-386\\
%to compile FreeFem++\\
%If there is an error : ``... -ldl : no such file or directory''\\
%Then you have to modify the Makefile-i386 which is in the directory src:\\
%-$>$ cd src \\
%Edit it (with xemacs for example):\\
%-$>$ xemacs Makefile-i386\\
%at line 1 : replace ``LIBLOCAL = -ldl'' by ``\#LIBLOCAL = -ldl''\\
%It will comment this line because -ldl is not on your machine.\\
%Then return to the main directory\\
%-$>$ cd\\
%and type:\\
%-$>$ make all HOSTTYPE=i-386\\
%\\
%At the end of compilation, a directory called ``c-i386'' is created.\\
%In this directory you can find the binary FreeFem++.\\
%\\
%You can now run an example:\\
%First open an X terminal:\\
%-$>$ startX\\
%In this terminal go in to FreeFem++v1.38:\\
%-$>$ cd FreeFem++v1.38\\
%and type:\\
%-$>$c-i386/FreeFem++ examples++-tutorial/adapt.edp\\
%You can then see the gnuplot window with the graphical results.\\
%\\

%\subsubsection{Compilation and Installation of tcl8.4.0 and  tk8.4.0 under Cygwin}
%Now if you want to use the Graphical User Interface of FreeFem++\\
%(called FFedit)\\
%you have to install the language TCL TK in which FFedit has been written.\\
%The version which works under cygwin is tcl8.4.0 and tk8.4.0\\
%The latest version when I wrote this is tcl8.4.6 and tk8.4.6\\
%\\
%DON'T USE IT \\
%\\
%It works under Linux and MacOsX but not under Cygwin.\\
%\\
%You have to download tcl8.4.0 and tk8.4.0 :\\
%For instance, go to Google.fr and type download tcl tk 8.4.0\\
%And choose the ``Sourceforge.net: Project Filelist''.\\
%Choose :\\
%tcl8.4.0-src.tar.gz and tk8.4.0-src.tar.gz\\
%When the download is finished you have to uncompress these directories:\\
%-$>$ tar zxvf tcl8.4.0-src.tar.gz\\
%-$>$ tar zxvf tk8.4.0-src.tar.gz\\
%\\
%\\
%tcl8.4.0 and tk8.4.0 will work under Cygwin only if you apply \\
%a patch on both:\\
%These patches are on the site:\\
%http://www.xraylith.wisc.edu/~khan/software/tcl\\
%Choose ``Tcl/Tk8.4.0 for Cygwin\\
%Click on ``very preliminary Cygwin ports of Tcl/Tk8.4.0\\
%You are then on the site ftp\\
%Follow the instructions of the README or follow these instructions:\\
%\\
%1) Run :\\
%-$>$ xemacs tcl-8.4.0-cygwin.diff\\
%By doing this, you create a new file called ``tcl-8.4.0-cygwin.diff''\\
%on the site ftp click on ``tcl-8.4.0-cygwin.diff''\\
%Do a Copy/Paste of the contain into your xemacs window and save it.\\
%\\
%2) Do the same with ``tk-8.4.0-cygwin.diff''\\
%\\
%Now you have to apply the patch in tcl8.4.0 and tk8.4.0\\
%The two previous patch files (.diff) must be respectively \\
%in tcl8.4.0 and tk8.4.0 directories.\\
%-$>$ cp tcl-8.4.0-cygwin.diff tcl8.4.0\\
%-$>$ cp tcl-8.4.0-cygwin.diff tk8.4.0\\
%(If the two files are one level under tcl8.4.0 and tk8.4.0)\\
%\\
%Now apply the patches:\\
%type:\\
%\\
%-$>$ cd tcl8.4.0\\
%-$>$ patch -p0 -s $<$ tcl-8.4.0-cygwin.diff\\
%\\
%-$>$ cd
%\\
%-$>$ cd tk8.4.0\\
%-$>$ patch -p0 -s $<$ tk-8.4.0-cygwin.diff\\
%\\
%Now you can compile and install TCL TK under Cygwin:\\
%\\

%
%* compilation and installation of tcl8.4.0\\
%\\
%Go in to the directory tcl8.4.0/win\\
%-$>$ cd tcl8.4.0\\
%-$>$ cd win\\
%Then type :\\
%-$>$ ./configure\\
%The two steps remaining are make and make install\\
%type\\
%-$>$ make\\
%The compilation starts, when finished install by typing:\\
%-$>$ make install\\
%\\
%When finished try to see if it works by typing:\\
%-$>$ tclsh84\\
%if ok quit by typing ctrl-c\\

%*Compilation and installation of tk8.4.0\\
%\\
%Go in to the directory tk8.4.0/win\\
%-$>$ cd tk8.4.0\\
%-$>$ cd win\\
%Then type :\\
%-$>$ ./configure\\
%The two steps remaining are make and make install\\
%type\\
%-$>$ make\\
%The compilation starts, if you have errors like :\\
%\\
%windres -o tk.res.o --include ``C:/cygwin/home/ly/tk8.4.0/generic'' \\
%--include ``C Option-I is deprecated for setting the input format,\\
% please use -J instead''\\
%windres : can't open icon file 'tk.ico' : no such file or directory\\
%\\
%This file 'tk.ico' is in fact in the directory win/rc\\
%You have to copy it in the directory 'generic':\\
%Be in tk8.4.0\\
%type :\\
%-$>$ cp win/rc/tk.ico generic/\\
%\\
%If you compile again you will see that there is the same \\
%errors with the files:\\
%``buttons.bmp'' ``cursor00.cur'' ``cursor02.cur'' ...etc... \\
%``wish.exe.manifest'' and ``wish.ico''\\
%\\
%Do the same for these files.\\
%For the cursor*.cur files do once the command:\\
%-$>$ cp win/rc/cursor*.cur generic/\\
%\\
%when finished install by typing:\\
%-$>$ make install\\
%\\
%When finished try to see if it works by typing:\\
%-$>$ wish84\\
%if ok quit by typing ctrl-c\\

%\subsubsection{Use}
%Now everything is ok to use FFedit and FreeFem++ under Windows by Cygwin.\\
%WARNING: if you work on the Cygwin terminal you will not be able \\
%to see the graphical results of FreeFem++.\\
%\\
%You have to run an X terminal and run FFedit under this X terminal:\\
%\\
%To run an X terminal under cygwin type on your Cygwin terminal:\\
%-$>$ startX\\
%\\
%An X terminal runs:\\
%Under this terminal:\\
%type\\
%-$>$ cd FFedit\\
%-$>$ ./FFedit.tcl\\
