Hello Matthias, I worked on that code and consider it a complete faillure. In many cases the OpenCASCADE algorithms would not find the intersections. The initial version was quite simple but at some point I started to stack one workaround on top of the other.
Currently I do not have the time to work on another method, but some algorithms available in CGAL look promising. But in that case I would probably use BRL-CAD to generate the geometry, and importing STEP into BRL-CAD might be sub-optimal. regards, Mark "Zenker, Dr. Matthias" <[email protected]> wrote: Hi, I have not done FEM calculations for some time (a year or so). The last time I did them (using gmsh and Elmer), I had the problem that in geometries imported as STEP files (generated by Solidworks), adjacent bodies have their own external surface, resulting in double surfaces at the interfaces. When I use the mesh generated by gmsh in a FEM calculation (I use Elmer), I get no thermal and electrical connection because the body meshes are not connected at the interface. There have been attempts to clean up double surfaces in gmsh, but I don't know if they have come to a success. Could someone of the developpers update me on this point? Thank you!
