OpenFOAM

Description

OpenFOAM (Open Field Operation and Manipulation) is primarily a C++ toolbox for the customisation and extension of numerical solvers for continuum mechanics problems, including computational fluid dynamics (CFD). It comes with a growing collection of pre-written solvers applicable to a wide range of problems. OpenFOAM was one of the first major scientific packages written in C++. It is produced by UK company OpenCFD Ltd. and is released open source under the GPL.

Installation on the RRZN-Computeservers

Usage on the RRZN-Computeservers

In order to use this software one needs to load the relevant module.  This is done like so:

    $ module load openfoam

OpenFOAM uses many environment variables, all of which are unable to be loaded along with the module.  This means, that you must run the following extra command in order to use OpenFOAM.

    $ source $foamDotFile

In case you see the error message  "module: command not found", you need to run the following command (usually the "module" command is already available):

    $ source /usr/share/Modules/init/`basename $SHELL`

Usage within the batch system

Here is an example batch script to help get you going running your first OpenFOAM application.

   #!/bin/bash
   #PBS -N openFOAM
   #PBS -M ich@meine.email.adresse.de
   #PBS -j oe
   #PBS -l nodes=1:ppn=1
   #PBS -l walltime=01:00:00
   #PBS -l mem=7gb
   # load the module
   . $MODULESHOME/init/bash
   module load openfoam
   # set the OpenFOAM environment
   source $foamDotFile
   # change to work dir:
   cd $PBS_O_WORKDIR
   <OpenFOAM-application>
