Introduction
OpenFOAM is a framework for developing application executables that use packaged functionality contained within a collection of approximately 100 C+ libraries. OpenFOAM is shipped with approximately 250 pre-built applications that fall into two categories: solvers, that are each designed to solve a specific problem in fluid (or continuum) mechanics; and utilities, that are designed to perform tasks that involve data manipulation.

source /usr/local/bin/s3proxy.sh
mkdir -p $HOME/sw/Containers/openfoam8/
cd $HOME/sw/Containers/openfoam8/
singularity pull docker://public.docker.itc.griffith.edu.au/openfoam/openfoam8-paraview56
mkdir -p $HOME/OpenFOAM/${USER}-8
cd $HOME/OpenFOAM/${USER}-8
singularity shell -B /export/home/${USER}:/home --pwd /export/home/${USER}:/home --pwd $HOME/OpenFOAM/${USER}-8 $HOME/sw/Containers/openfoam8/openfoam8-paraview56_latest.sif
Once inside the shell:
source /opt/openfoam8/etc/bashrc
mkdir -p $FOAM_RUN
#echo $FOAM_RUN
#/export/home/s5072653/run
cd $FOAM_RUN
cp -r $FOAM_TUTORIALS/incompressible/simpleFoam/pitzDaily .
cd pitzDaily
blockMesh
simpleFoam
paraFoam
To run it as a batch job, create a launcher script:
1. Launcher Script
>>>>>>>
vi ~/pbs/openfoam8Launcher.sh
#!/bin/bash
source /opt/openfoam8/etc/bashrc
mkdir -p $FOAM_RUN
cd $FOAM_RUN
cp -r $FOAM_TUTORIALS/incompressible/simpleFoam/pitzDaily .
cd pitzDaily
blockMesh
>>>>>>>>
#make it executable
chmod +7 ~/pbs/openfoam8Launcher.sh
2. pbs script
vi ~/pbs/openfoam8.pbs01
>>>>>
!/bin/bash
#PBS -m abe
#PBS -M shusen.chen@griffithuni.edu.au
#PBS -N TestOpenFoam8
#PBS -q workq
#PBS -l select=1:ncpus=8:mem=2gb,walltime=3:00:00
cd $PBS_O_WORKDIR
#An example is as below. Modify accordingly to suit your needs
!/bin/bash
#PBS -m abe
#PBS -M shusen.chen@griffithuni.edu.au
#PBS -N TestOpenFoam8
#PBS -q workq
#PBS -l select=1:ncpus=8:mem=2gb,walltime=3:00:00
cd $PBS_O_WORKDIR
#An example is as below. Modify accordingly to suit your needs
singularity exec -B ~:/home --pwd ~:/home --pwd /home $HOME/sw/Containers/openfoam8/openfoam8-paraview56_latest.sif "/home/pbs/openfoamLauncher8.sh"
exit
sleep 2
