FreeFOAM is developed and tested on Linux, but should work with other Unix style systems, notably Mac OS X ©. The support for Microsoft Windows is a goal, which, however, is still far off.
In order to build FreeFOAM you need to have CMake with version 2.8.2 or newer installed. In order to follow the INSTALL instructions, make sure that you also install the package contain the curses GUI ccmake if using a package manager (e.g. on Linux systems. For Debian and Ubuntu the package is called cmake-curses-gui). http://cmake.org
CMake requires a native build system. On Unix-like platforms GNU Make is recommended. http://www.gnu.org/software/make
template expressions. The g++ compiler from GCC-4.3 and above will do fine. http://gcc.gnu.org
The flex lexer generator. Version 2.5.33 is known to work. For more recent versions there have been reports of problems. http://flex.sourceforge.net
zlib compression library. http://www.zlib.net
The SCOTCH graph partitioning library. Version 5.1.7 is know to work. http://www.labri.fr/perso/pelegrin/scotch
The Python interpreter. Version 2.6 is known to work, but care has been taken to make FreeFOAM work with versions from 2.4 on, including 3.x.
|In order to build the man pages or the user guide, AsciiDoc is required which has not yet been ported to Python 3. This is why Python version 2 is also required (only at build-time for the documentation) if a Python 3 interpreter is used.|
In order to create the man-pages or the XHTML and PDF documentation you need to have a fully working AsciiDoc toolchain installed. Versions newer than 8.5 are known to work. AsciiDoc itself needs Python 2.4 or newer (but not 3.x), xsltproc, xmllint from libxml2, the DocBook XML DTD’s and the DocBook XSL stylesheets. Refer to the AsciiDoc installation instructions for the details. Also note, that AsciiDoc versions 8.6.5 and 8.6.6 contain a bug which makes it depend on Python 2.5 and newer. http://www.methods.co.nz/asciidoc
Asymptote, the powerful descriptive vector-graphics language, is used to generate many of the graphics in the User Guide. Note that Asymptote
If you want to build the PDF version of the user guide, it is recommended that you have dblatex installed, as the generated output is superior to that generated with the alternative, Apache FOP. Since dblatex uses LaTeX as its rendering backend, it depends on a LaTeX installation. http://dblatex.sourceforge.net
Automatic API-documentation generator. Required to build the source documentation. http://www.doxygen.org
If you want to build the PDF version of the user guide but can’t or don’t want to install dblatex, Apache FOP can be used instead. It’s output, however, is inferior to that of dblatex, especially that of the formulas. http://xmlgraphics.apache.org/fop
To check out a current development version of FreeFOAM, git is required. http://git.or.cz
The graphs in the User Guide and the API documentation are require the Graphviz package for their generation. http://graphviz.org
Both, dblatex and Asymptote require a decent LaTeX installation. If you install LaTeX via a package manager, make sure that you also install the packages providing the units.sty LaTeX package and the extra fonts. On Debian and Ubuntu systems, they are called texlive-latex-extra and texlive-fonts-recommended, respectively. http://latex-project.org
pro-STAR © input/output library. FreeFOAM can build this automatically for you. Please refer to the INSTALL file for license restrictions. https://wci.llnl.gov/codes/visit/3rd_party/libccmio-2.6.1.tar.gz
Some of the provided tutorial cases require the M4 macro processor. http://www.gnu.org/software/m4/
If you enable MathJax for math-rendering in the XHTML version of the user guide, but don’t want to use the shared installation over the network, you can install MathJax locally. http://www.mathjax.org
The METIS graph partitioning library, version 5.0.1. If your package manager doesn’t contain it, you can also have FreeFOAM build it automatically for you (see the installation section). http://glaros.dtc.umn.edu/gkhome/metis/metis/overview
MGRIDGEN is a grid coarsening library for multi-grid solvers. FreeFOAM can build this automatically for you. Please refer to the INSTALL file for license restrictions. http://glaros.dtc.umn.edu/gkhome/mgridgen/overview
The FreeFOAM utility para requires this visualization application, version 3.8 or later. http://www.paraview.org
In order to run FreeFOAM in parallel, a communications library is required. Currently the only available options is MPI (Message Passing Interface). There are many implementations of the MPI standard. The one that has been tested and is known to work with FreeFOAM is OpenMPI.
If you use an MPI library, the ParMetis library is required. If your package manager doesn’t contain this library, FreeFOAM can build it automatically for you (refer to the installation notes below). http://glaros.dtc.umn.edu/gkhome/metis/parmetis/overview
The setSet utility can be used in an interactive mode which is greatly improved if using the GNU Readline library for history and command line editing support. http://gnu.org/s/readline
For exhaustive installation and basic usage instructions, refer to the INSTALL file.
All the applications and the frequently used script utilities come with a brief man-page. Unfortunately, most of them are little more than stubs and need more work. The man-page freefoam(1) gives a short overview over all applications and utilities and documents the FreeFOAM configuration options.
API-documentation is available from http://freefoam.sourceforge.net/doc/v0.1.2/API.
Further, most FreeFOAM applications and utilities support the -doc and -srcDoc options, which will automatically display the API-documentation and the source code of the application, respectively.
