OpenFOAM-1.7.1

Following is an example job script:

#BSUB -o OpenFOAM_1.7.1.out
#BSUB -e OpenFOAM_1.7.1.err
#BSUB -R "span[ptile=12]"
#BSUB -n 36

# initialise the environment
export WM_64=ON

. /etc/profile.d/modules.sh
module load openfoam/1.7.1
. $foamDotFile

export myoptions="-parallel"

# run the job
cd $LS_SUBCWD
$MPIROOT/bin/mpirun -x LD_LIBRARY_PATH -np 36 simpleFoam $myoptions

Note: OpenFOAM 2.0.1 is similar

OpenFOAM-1.5-1

Example job script:

#BSUB -o OpenFOAM-1.5-1.out
#BSUB -e OpenFOAM-1.5-1.err
#BSUB -R "span[ptile=12]"
#BSUB -n 16

# initialise the environment
. /etc/profile.d/modules.sh

# load OpenFOAM module
module load openfoam/1.5-1
. $foamDotFile

# customise the run
export WM_64=ON
export myoptions="-parallel"

jobs="foamProMesh checkMesh renumberMesh caseSetup simplePorousFoam"
cd $LS_SUBCWD

for job in `echo $jobs`
do
case "$job" in 
                "renumberMesh"   )   options="$myoptions -overwrite" ;;
                *                )   options="$myoptions" ;;
esac

# run the job
$MPIROOT/bin/mpirun -x LD_LIBRARY_PATH -np 16 $job $myoptions 
done

OpenFOAM on the Sun Cluster

First remove any existing modules and load the openfoam module. Then source the setup scripts and create your own runtime area and run the test script.

module purge
module load openfoam
. $foamDotFile
mkdir -p $FOAM_RUN/run
foamInstallationTest

After that its up to you. Please see the OpenFOAM tutorials for help: http://www.openfoam.com/docs/user/ . Here is a simple script for submitting a 4-core parallel OpenFOAM job.

rm *.sh.*
rm interFoam.sh
EXEC="/panfs/dl/home/openfoam/OpenFOAM/OpenFOAM-1.6/applications/bin/linux64GccDPOpt/interFoam -parallel"
export QSUB_OPTIONS="-V"
