OpenFOAM installation and running instructions

First copy the apps directory to the cluster. The azhpc-scp can be used to do this:

azhpc-scp -r $azhpc_dir/apps hpcuser@headnode:.

Alternatively you can checkout the azurehpc repository but you will need to update the paths according to where you put it.

Install OpenFOAM from source

For this the headnode needs to be a HC node with CentOS-HPC-7.6 upwards

azhpc-run -u hpcuser $azhpc_dir/apps/openfoam_org/full_openfoam.sh

Install OpenFOAM from tarball

azhpc-run -u hpcuser $azhpc_dir/apps/openfoam_org/tar_openfoam.sh

Run OpenFOAM

OpenFOAM is run on the headnode. First, Log-in to headnode as hpcuser (using "azhpc-connect -u hpcuser headnode"). Then git clone the azhpc repo

Run motorbike_2m model

qsub -l select=1:ncpus=30:mpiprocs=30,place=scatter:excl $azhpc_dir/apps/openfoam_org/motorbike_2m.sh

Run OpenFoam tutorial (Not working yet. Does not recognize changing core counts)

qsub -l select=1:ncpus=30:mpiprocs=30,place=scatter:excl -- $azhpc_dir/apps/openfoam_org/run_tutorial.sh incompressible simpleFoam rotorDisk

You can run a different tutorial by changing the first (Tutorial name e.g incompressible), second (Solver, e.g simpleFoam) and third (case name, e.g SimpleFoam) arguments.
