I have not yet installed or run OpenFoam, and I couldn't find anything after a quick look through the documentation, so please forgive this very basic question:

How do I read in geometry to the mesher? Can I import iges or any CAD format? or do I have to output lists of points to format as an input file?

You need to generate complex meshes for OpenFOAM in an external application like Harpoon, ICEM, Gridgen, Netgen, Gambit etc. each of which has its own import requirements. (Check mesh conversion in the manual). The current release of OpenFOAM only has a basic block based mesh generator.

Hi Eugene,

You mentioned above Gridgen. Which utility converts Gridgen mesh to FOAM mesh?

Thanks,

You either export a star or fluent mesh and then convert that into Foam format.
