Hallo everybody,
I am looking for a way to generate a 3d complex mesh starting from stl file, for chtMultiRegion OpenFOAM 1.7 solver.
sHM works well if I have only one stl file (also divided in many patches).
The problem is when I try to use chtMultiRegion, with more than one region and of complex geometry: it means not a simple box or a cylinder, but a scanned geometry of real objets.
No upgrade after this post:
So the multi region approach of snappyHexMesh can only work in block mesh like geometries…

Any idea or help to skip the problem. Or someone could suggest me another open-source tool working in such case, for example "Salome"?
Many thanks

as partial solution: form OpenFOAM 2.0 it's possible generate multi domain meshes. However in chtMultiRegion solver you can't add layers , so ... for detailed mesh generation it could be better use different tools.
