Dear Dr. Rene Schneider, Thanks for the reply. I tried the physical volume but could you please tell me if it is possible to start the node numbering and the element numbering in the exported mesh from 1. If I created the 3D mesh from extrusion, the physical volume exports only the volume elements but the numbering does not start from 1. I use my own code for the analysis and I dont want to do much preprocessing myself if it is possible from within gmsh.
