Well, IMHO, this is not a pythonOCC nor an OCC issue. It's rather a conceptual problem. Let me sum-up my understanding (tell me if I'm wrong): (1) you have a STEP geometry that you want to compute, (2) you mesh this geometry, (3) perform FEM on the mesh, (4) you want to export the deformed mesh back to a STEP geometry. The problem is then: (1) BREP geometry (exact) (2) Mesh geometry (approximation of 1) (3) Deformed Mesh geometry (not exact) (4) back to exact geometry (BREP). I was at a french scientific conference a few months ago and a guy talked about that subject. It's still quite open... The proof-of-concept was achieved for a cube or a sphere, but that's all. According to what I understood, it's a need expressed by the automotive industry to optimize the fitting of the parts of an engine. A lot of scientists work on that issue (unfortunately, I'm not the guy who can help you). This is the homepage of the conference (slides in english): http://www.univ-valenciennes.fr/sp/CAOCalcul/programme.php I suggest you the reading of Alain RASSINEUX's presentation: http://www.univ-valenciennes.fr/sp/CAOCalcul/document/CAO%20CALCUL/Presentations/05%20-%20ARASSINEUX.pdf Cheers, Thomas _______________________________________________ Pythonocc-users mailing list Pythonocc-users@gna.org https://mail.gna.org/listinfo/pythonocc-users
