Using gmsh to draw mesh and import it into FreeFem results in an error

General Discussion

Hello, I am a newcomer to using FreeFem. I would like to know why when I export my 3D mesh, which I drew in Gmsh, in the （.msh） format, and I choose ASCII 2 with the other two options unchecked, the result in FreeFem only shows the surfaces that I defined with physical groups? Why is that? Thank you very much for your answer.

you can try .mesh format

Thank you very much for your answer. However, I have two more questions: When using the .mesh format in FreeFem, do I still use the gmshload3 function to import it? And can I still use the surface physical groups that I set in Gmsh in FreeFem?

th = readmesh3(MeshFileName);
