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)
| Tip |
|---|
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 |
| Warning | ||
|---|---|---|
| ||
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.
