How to assign physical groups in imported mesh
Hello! I converted a .vtk file into a .msh file, and I want to assign physical groups (3 surfaces and 1 volume). But when I try to do that (for example press surface to create a surface group) I am unable to do so. Also I am able to visualise only the mesh, not the geometry wireframe, am I doing something wrong? Or are there specific steps to deal with this? I have attached the converted file (.msh)
thank you in advance :converted16_mesh.msh
