[Gmsh] Question about STL files

[mlegrand at student.ulg.ac.be]

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,
