From OpenFOAMWiki

I have developed ennovaCFD for OpenFOAM, a commercial pre- and post-processing tool for OpenFOAM. It can generate tetrahedral and polyhedral meshes and can directly export them in OpenFOAM format. It supports OpenFOAM case setup including incompressible, compressible, multiphase and heat transfer solvers. Personally I have shared my knowledge about OpenFOAM and CFD on my blog and SlideShare.
