Hello, I've imported a CAD geometry (same problem with IGES and STEP). The file is an assembly of two parts. When I open it in gmsh everything works fine. gmsh shows two volumes and when I am doing the surface mesh (2D) I get a perfect mesh. The contact surface of the two volumes is meshed as well, that is exactly what I want. But when I try to do volume meshing gmsh crashes. In the Linux version without a message. In the windows version with the following message:
Microsoft Visual C++ Runtime Library Assertion Failed! Program C:\Program Files (X86)\gmsh\gmsh.exe File: tetgen.cxx Line: 22506 Expression: matchflag == true ... The error occurs with all tested assembly files that consinst of multiple volumes. Perhaps someone can help! The goal is to mesh a assembly consisting of two parts. And the contact surface of the volumes should be meshed as surface. Like gmsh does in the surface meshing step described above. But the 3D meshing crashes. Thanks a lot, Sammy
