Running OpenFOAM®
Official documentation
How to run OpenFOAM
OpenFoam is provided via the new software environment
STEP 1: log into Axiom frontend
ssh <username>@axiom-front1.unil.ch
STEP 2: submit batch job
Go to your OpenFOAM project directory and submit the batch job with:
sbatch sbatch_openfoam_job.sh
where the script sbatch_openfoam_job.sh looks something like the example given below.
Here we use a problem that was decomposed in 4 sub-domains and explicitly spread over two nodes to illustrate the use of MPI for processing in "-parallel" mode.
#!/bin/bash -l
#SBATCH --account=<account_to_use>
#SBATCH --nodes 2
#SBATCH --ntasks 4
#SBATCH --partition=axiom
#SBATCH --constraint=AVX2
#SBATCH --mem-per-cpu=5G
#SBATCH --time=01:00:00
