Hi Courtney, I would use your approach 1, but make sure that "save all (ignore physical groups)" is checked when saving the mesh. Remark concerning ElmerGUI: If you don't see volume elements, check Model->Summary. Volume elements can be made visible with View->Volume Mesh.

Simply opening my .step file and meshing 1, 2, and 3D. 2. Creating a volume physical group using the GUI, and then meshing as above when I attempt to open the .msh file in Elmer, I get 2 different responses: 1. When I open the first file, it opens as usual, but opens with no volume elements 2. When I open the second file, it does not open at all - Elmer says that there are 0 elements in the file. I appreciate your assistance - any advise is much appreciated!

What you can check: Are you sure you generated a 3D mesh? When you open your .msh file with gmsh, do you see volumes in Tools->Visibility?

I have a .step file (attached) for this geometry. When I attempt to mesh this geometry and open it in Elmer (for additional analysis), I noticed that the mesh has " 0 volume elements". Would you be able to assist with this issue? I'm thinking I may not have the correct options setup for meshing a geometry such as this. I should point out that I am not very experienced with finite element analysis, as this is my first attempt at using software such as gmsh and elmer. Thank you for your time!
