=== Getting started ===

To use OpenFOAM, load an OpenFOAM module:

module load openfoam

to always get the latest stable version. The OpenFOAM modules will load the appropriate version of MPI for you. Loading any other MPI modules either before or after an OpenFOAM module is likely to cause problems.

Unless otherwise noted in the module name, OpenFOAM will be compiled with GCC and [[Intel_MPI | Intel MPI]] for performance reasons.

To load a number of convenient aliases into your environment, add the appropriate line below to your shell configuration files:

source $FOAM_INST_DIR/OpenFOAM-1.6/etc/aliases.sh
source $FOAM_INST_DIR/OpenFOAM-1.6/etc/aliases.csh

The following job script should be sufficient to get you started with running parallel jobs:

#!/bin/bash

. /etc/profile.d/modules.sh
module load openfoam

cd $PBS_O_WORKDIR

# don't use -np or -machinefile
mpirun <foamExec> <otherArgs> -parallel | tee logfile

You needn't (and shouldn't) specify a hostfile or number of processors; mpirun will automatically use $PBS_NODEFILE as the hostfile. See the [[Intel_MPI | Intel MPI documentation]] for more info.

=== Pre- and post-processing ===

Resource-intensive pre- and post-processing should be done on a compute node, not on a login node. See our info about [[STAR-CCM%2B#Pre-_and_post-processing | pre- and post-processing]] for STAR-CCM+ for how to run interactive and graphical applications on compute nodes.

=== Documentation ===

The official OpenFOAM documentation is available at [http://www.opencfd.co.uk/openfoam/doc/index.html OpenFOAM]. The [http://openfoamwiki.net/index.php/Main_Page OpenFOAM Wiki] is also useful.
