OpenFOAM (with ParaView)¶
This uses Singularity containers, so you should refer to that page first for general information.
OpenFOAM and ParaView have been installed from the Ubuntu 16.04 Docker image provided by OpenFOAM people. It has minimal amount of other software installed.
Parallelization is done against Triton’s OpenMPI, so using this container with other OpenMPI modules is discouraged.
New image (singularity-openfoam)¶
module load singularity-openfoam and use
OpenFOAM is installed in
/opt/OpenFOAM. The OpenFOAM
file is automatically sourced when you exec or shell within the image
PATH and so on.
Old image (OpenFOAM)¶
This is quite similar to the new image.
Within the container OpenFOAM is installed under
PATH is automatically appended
with their respective paths so all program calls are available
(This has not been updated to the new image yet. To change to new
image, don’t do the
module use and instead just load
This example shows how you can run damBreak example. Firstly, let’s load the OpenFOAM module and create a folder for the example:
module use /share/apps2/singularity/modules module load OpenFOAM mkdir damBreak cd damBreak
Secondly, let’s use singularity shell to copy example data files to the folder and to initialize the simulation.:
cp -r /opt/openfoam4/tutorials/multiphase/interFoam/laminar/damBreak/damBreak/0 . cp -r /opt/openfoam4/tutorials/multiphase/interFoam/laminar/damBreak/damBreak/system . cp -r /opt/openfoam4/tutorials/multiphase/interFoam/laminar/damBreak/damBreak/constant . blockMesh decomposePar exit
After this one can submit the following slurm
script with sbatch to solve the problem:
#!/bin/bash #SBATCH -p short #SBATCH -t 00:30:00 #SBATCH -n 4 #SBATCH --mem=4G module use /share/apps2/singularity/modules module purge module load OpenFOAM srun singularity_wrapper exec interFoam -parallel
Paraview can be started similarly with this
#!/bin/bash #SBATCH -p short #SBATCH -t 00:10:00 #SBATCH -n 1 #SBATCH --mem=8G module use /share/apps2/singularity/modules module purge module load OpenFOAM singularity_wrapper exec paraview
