Hello, Thank you for the response. I shall try it out.

There are several things I would want to clarify, but I would like to start with “Physical tags”. If I have defined “Physical Points”, “Physical Surface”, and “Physical Volume” in my .geo file, I get the physical tags in the “.msh” file. When I load this mesh in DMPlex, and view the DM: call DMView(globalMesh, PETSC_VIEWER_STDOUT_WORLD,err_PETSc) CHKERRQ(err_PETSc) This is the output I get: DM Object: n/a 1 MPI process type: plex n/a in 3 dimensions: Number of 0-cells per rank: 14 Number of 1-cells per rank: 49 Number of 2-cells per rank: 60 Number of 3-cells per rank: 24 Labels: celltype: 4 strata with value/size (0 (14), 6 (24), 3 (60), 1 (49)) depth: 4 strata with value/size (0 (14), 1 (49), 2 (60), 3 (24)) Cell Sets: 1 strata with value/size (8 (24)) Face Sets: 6 strata with value/size (2 (4), 3 (4), 4 (4), 5 (4), 6 (4), 7 (4)) I was expecting to get the “Node Sets” or “Vertex Sets” also. Is my assumption wrong? If yes, then how can one figure out the boundary nodes and their tags where I want to apply certain boundary conditions? Currently we apply boundary conditions on faces, therefore “Face Sets” was enough. But now we want to apply displacements on certain boundary nodes. I have also attached the .geo and .msh file (hope you can open it) The Petsc version I am using is 3.18.6.
