[Beowulf] Openfoam advice

[Benson Muite]

Hi Faraz,

Last looked at OpenFOAM 4-X
https://github.com/OpenFOAM/OpenFOAM-4.x
Though development has migrated to
https://develop.openfoam.com/Development/OpenFOAM-plus

Steps I used in a bash build script for 4-X on a cluster with OpenMPI, 
qt, zlib and cmake already installed are below. Scaling for OpenFOAM 
depends significantly on what is being simulated.

Regards,
Benson
