multiple patches from gmsh to foam

shangzung · October 6, 2009, 12:12

Hello!

I am desperately trying to convert a mesh from gmsh to OpenFOAM. My mesh is a simple cube with a smaller cube inside. However, when I convert my mesh to OpenFOAM with gmshToFoam, I get only one patch (patch 0) which I think is the bigger cube but the smaller cube is ignored and is only visible in wireframe but is not a patch.

1. How do I manage to convert my .msh so that I get multiple patches?

I tried gmsh2ToFoam but it does not compile on OpenFOAM 1.6.

2. Is there maybe a better meshing tool for OpenFoam meshes?

Thanks a lot!
