- The OpenFOAM (Open Field Operation and Manipulation) CFD Toolbox is a free, open source CFD software package. OpenFOAM has an extensive range of features to solve anything from complex fluid flows involving chemical reactions, turbulence and heat transfer, to solid dynamics and electromagnetics.
- OpenFOAM homepage and Tutorials.
- OpenFOAM 2.2.1 includes ParaView 3 and the PV3Readers module. It also contains Swak4foam OF 2.2.
- OpenFOAM 2.3.x includes ParaView 4 and the PV4Readers module.
- OpenFOAM requires substantial preparation of your environment. In order to run OpenFOAM commands (such as
blockMesh, etc), you must load a modulefile followed by sourcing a configuration script.
- Here is an example of a serial submission script for OpenFOAM 2.3.0:
#$ -cwd #$ -l h_rt=01:00:00 module purge module load gcc/4.6.4 openmpi/gcc openfoam/2.3.0 source $OPENFOAM/etc/bashrc blockMesh icoFoam
- Here is an example of a parallel submission script for OpenFOAM 2.3.0:
#$ -cwd #$ -l h_rt=01:00:00 #$ -pe ompi* 4 module purge module load gcc/4.6.4 openmpi/gcc openfoam/2.3.0 source $OPENFOAM/etc/bashrc blockMesh mpirun icoFoam -parallel
- Mesh preparation (
blockMesh) may be fast enough to be done at the command line (see Head Node Policies). The solver (
icoFoamand others) is usually the most expensive step and should always be submitted as a Grid Engine job except in very small test cases or tutorials.
- OpenFOAM can emit a lot of debugging information in very frequent small writes (e.g. hundreds per second). This may lead to poor performance on our network file systems. If you are in stable production and don't need the debug output, you can reduce or disable it with:
$ mkdir -p $HOME/.OpenFOAM/$WM_PROJECT_VERSION $ cp $WM_PROJECT_DIR/etc/controlDict $HOME/.OpenFOAM/$WM_PROJECT_VERSION/
- followed by editing the
$HOME/.OpenFOAM/$WM_PROJECT_VERSION/controlDict, changing flags from values >0 to 0. (Contribution from C. Lane)
