CatalyticFOAM¶
CatalyticFOAM is a CFD solver for heterogeneous reacting flows with detailed kinetic mechanisms, developed on top of the OpenFOAM framework.
CatalyticFOAM is available as a module, which calls an Apptainer container on Apocrita.
Usage¶
To run the default version of CatalyticFOAM, simply load the catalyticfoam module:
module load catalyticfoam
catalyticfoam [command]
The command must be a valid CatalyticFOAM or OpenFOAM command. A few examples are listed below:
catalyticfoam foamExec
catalyticfoam blockMesh
catalyticfoam catalyticPimpleFOAM
Add the -help parameter after any CatalyticFOAM command for usage
information and examples.
Example jobs¶
In both examples below, substitute FOAM_PROJECT with your actual CatalyticFOAM
project directory.
Serial job¶
Here is an example job running on 1 core and 5GB of memory:
#!/bin/bash
#$ -cwd
#$ -j y
#$ -pe smp 1
#$ -l h_vmem=5G
module load catalyticfoam
cd FOAM_PROJECT
catalyticfoam blockMesh
mpirun -np $NSLOTS catalyticfoam catalyticPimpleFOAM
Parallel job¶
Here is an example job running on 96 cores across 2 ddy nodes with MPI:
#!/bin/bash
#$ -cwd
#$ -j y
#$ -pe parallel 96
#$ -l infiniband=ddy-i
#$ -l h_rt=240:0:0
module load catalyticfoam
cd FOAM_PROJECT
catalyticfoam blockMesh
mpirun -np $NSLOTS catalyticfoam catalyticPimpleFOAM
