Opis
OpenFOAM je besplatan i otvoreni softver za numeričko rješavanje problema u računalnoj dinamici fluida i srodnim disciplinama. OpenFOAM ima široku primjenu u industriji, akademskim i istraživačkim institucijama. Može se koristiti za modeliranje protoka fluida u raznim sustavima.

Primjer pokretanja posla (Supek)
Svaki OpenFOAM posao započinje sa učitavanjem OpenFOAM modula i postavljanjem odgovarajućeg okuženja naredbama:
module load scientific/openfoam/2212
source $OF_activate
. ${WM_PROJECT_DIR:?}/bin/tools/RunFunctions
OpenMPI-5.0.1
Ukoliko koristite verzije openfoam-aa prevedene sa openMPI-5.0.1, prilikom pozivanja naredbe mpiexec potrebno je dodati i --hostfile $PBS_NODEFILE opciju.
Primjer snappyHexMesh:
mpiexec --hostfile $PBS_NODEFILE snappyHexMesh -parallel
U primjeru niže pokrenuti će se posao na 128 jezgri, u "cpu" redu čekanja.
#!/bin/bash
#PBS -N run-OF
#PBS -q cpu
#PBS -j oe
#PBS -l select=128
#PBS -l place=pack
