From OpenFOAMWiki

I've developed ennovaCFD for OpenFOAM, a commercial pre- and post-processing tool for OpenFOAM. It can generate tetrahedral and polyhedral meshes and directly export them in OpenFOAM format. You can set up many OpenFOAM solvers on GUI(incompressible, compressible, heat transfer, multiphase, adjoint etc.). Personally I've shared my knowledge about OpenFOAM and CFD on my blog and SlideShare.
