Dear Lei Zhang,
By default the gmsh format read by getfem is the format 1.
By default the format used by gmsh is currently the format 2.
You have two solutions :
- you register your mesh as format 1 instead of 2 in gmsh.
- you use in getfem:
""getfem::import_mesh("t1.msh","gmshv2",m1);"" instead of:
""getfem::import_mesh("t1.msh","gmsh",m1);""
Best regards,
Ronan

Dear developers,
Thanks for developing Getfem++. I am trying to use this package in my research.
Could you help with the following problem? Thanks a lot in advance!
When I tried to use import_mesh to import GMSH file into getfem like this:
getfem::mesh m1;
getfem::import_mesh("t1.msh","gmsh",m1);
I got the following error,
