Dear Sir,
I am a student at the University of Liège using gmsh for my thesis with
Professor D. Ruffoni. I use it to produce stl files for a 3D printer. As it is
a multi-material 3D printer, I need several stl files (one per material). I
tried to divide the part into several physical entities, but it did not work.
It works if I do not define physical entities and if I do it only part per part
but then the orientation of the elements is not good. Could you give me a hint
on how to solve this problem?
Thanks for your help,
