First step in using the program is to load module file which will set up the environment. To do so please run the command

<pre>
module load openfoam/2.3.0
</pre>

The script will ask you to load the bashrc file. Run the command:

<pre>
source /share/apps/openfoam/2.3.0/OpenFOAM-2.3.0/etc/bashrc
</pre>

Make directory for the project and put all your project files there. Change to this directory.

Create a SLURM script for the type of job you want to use:

For sequential job

<pre>
#!/bin/bash
#SBATCH --partition production
#SBATCH --job-name <name of your run>
#SBATCH --nodes=1
#SBATCH --ntasks=1

# Find out name of master execution host (compute node)
echo ""
echo -n ">>>> SLURM Master compute node is: "
hostname

# Change to working directory
cd $SLURM_SUBMIT_DIR

echo ">>>> Begin serial run ..."
echo ""

<name of open foam program> log.<open_foam_program> 2>&1

echo ""
echo ">>>> End serial Run ..."

</pre>

For MPI run on 4 cores:

<pre>
#!/bin/bash
#SBATCH --partition production
#SBATCH --job-name <name of your run>
#SBATCH --nodes=1
#SBATCH --ntasks=1

# Find out name of master execution host (compute node)
echo ""
echo -n ">>>> SLURM Master compute node is: "
hostname

# Change to working directory
cd $SLURM_SUBMIT_DIR

echo ">>>> Begin parallel run ..."
echo ""

mpirun -np 4 <name of open foam program> -parallel log.<open_foam_program> 2>&1

echo ""
echo ">>>> End parallel run ..."

</pre>
