  • $\begingroup$ thank you for taking the time to walk through this. As I mentioned, user21's answer works fine for displaying the "bmesh" ElementMarkers alongside the "mesh" wireframe. But if you change your last line to display the marked boundary elements of the "mesh" itself, you will get the scrambled picture I posted. For applying boundary conditions, I need to have these markers correctly set in the actual ElementMesh, not a boundary mesh (please correct me if I am mistaken). Perhaps I am missing something $\endgroup$ Commented Apr 16, 2020 at 23:37

  • $\begingroup$ @bob800 You are welcome! I believe the mesher under the hood may reorder coordinates and renumber the incidents from the user supplied and that is how they got garbled. $\endgroup$ Commented Apr 17, 2020 at 2:44
