== Installation ==
First you need to check the required packages.  They can be obtained using aptitude.  Here is a complete list for the platform:

{{Command|<nowiki>aptitude search build-essential</nowiki>}}
{{Command|<nowiki>aptitude search flex</nowiki>}}
{{Command|<nowiki>aptitude search bison</nowiki>}}
{{Command|<nowiki>aptitude search cmake</nowiki>}}
{{Command|<nowiki>aptitude search zlib1g-dev</nowiki>}}
{{Command|<nowiki>aptitude search libopenmpi-dev</nowiki>}}
{{Command|<nowiki>aptitude search openmpi-bin</nowiki>}}
{{Command|<nowiki>aptitude search qt4-dev-tools</nowiki>}}
{{Command|<nowiki>aptitude search libqt4-dev</nowiki>}}
{{Command|<nowiki>aptitude search libqt4-opengl-dev</nowiki>}}
{{Command|<nowiki>aptitude search gnuplot</nowiki>}}
{{Command|<nowiki>aptitude search libxt-dev</nowiki>}}
{{Command|<nowiki>aptitude search freeglut3-dev</nowiki>}}
{{Command|<nowiki>aptitude search libqtwebkit-dev</nowiki>}}
{{Command|<nowiki>aptitude search libreadline-dev</nowiki>}}
{{Command|<nowiki>aptitude search libncurses-dev</nowiki>}}
Then you must create a folder that is accesible for all the users, like /usr/local or /opt.  
{{Command|<nowiki>mkdir /usr/local/OpenFOAM</nowiki>}}
In that folder use the wget command to download the source package for both the base OpenFOAM and Third Party Scripts:
{{Command|<nowiki>wget http://downloads.sourceforge.net/foam/OpenFOAM-2.3.1.tgz</nowiki>}}
{{Command|<nowiki>wget http://downloads.sourceforge.net/foam/ThirdParty-2.3.1.tgz</nowiki>}}
Untar the files
{{Command|<nowiki>tar -xvzf OpenFoam-x.x.x
tar -xvzf ThirdParty-x.x.x</nowiki>}}
{{Note|<nowiki>The compilers must be:
GCC: 4.5.0 and above
LLVM Clang: 3.4 and above
Intel ICC: 14.0.1</nowiki>}}
Edit /etc/profile.d/apps.sh and add the following lines.  Then replicate these changes in the apps.sh file of every node.
{{File|/etc/mail/aliases|<pre><nowiki>
...
export FOAM_INST_DIR=/usr/local/OpenFOAM
foamDotFile=$FOAM_INST_DIR/OpenFOAM-2.3.1/etc/bashrc
[ -f $foamDotFile ] && . $foamDotFile
...
</pre></nowiki>}}
Run ./Allwmake
{{Command|<nowiki>cd $FOAM_INST_DIR/OpenFOAM-2.3.1/</nowiki>}}
{{Command|<nowiki>./Allwmake</nowiki>}}
Test!
{{Command|<nowiki>cd $FOAM_INST_DIR/OpenFOAM-2.3.1/bin/
./foamInstallationTest
</nowiki>}}
