Physical Group Meshing
 

Hello everyone.

Using GMSH, I was recently able to create a tetrahedral mesh of a tube's surfaces without implementing physical groups. However, when I introduced physical groups to the .geo code, using 2D meshing resulted in only the physical group points being visible! Is there any way to create a mesh that includes both ungrouped surfaces and grouped points?

Thank you very much. :)

I am not sure that I have got your question. If you want both the points and surfaces included, you can just group the surfaces as a physical surfaces. For how to do it, you can find it easily from the tutorial for GMSH.
