Thanks for the clarification. However, would it be more consistent to differentiate between 0D (vertex sets), 1D (edge sets), 2d (faces) and 3D (cell sets)? If I want to now apply boundary condition on a face with tag 1, it would contain the 4 edges making up that face and an additional edge with the same physical tag? Basically, I can’t differentiate between the two entities Thanks, Sharan Group - Theory & Simulation Department of Microstructure Physics & Alloy Design From: Matthew Knepley <[email protected]> To: Sharan Roongta <[email protected]> Cc: "[email protected]" <[email protected]> Sent: 13/12/2023 12:51 AM Subject: Re: [petsc-users] difference in Face Sets in latest petsc release On Tue, Dec 12, 2023 at 5:50 PM Sharan Roongta <[email protected]> wrote: Hello, I see discrepancy in the size/value of the 'Face Sets' printed in the current release v3.20.2 , and v3.18.6 Attached is the .msh file -dm_view with v3.18.6 DM Object: Generated Mesh 1 MPI process type: plex Generated Mesh 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 (1 (24)) Face Sets: 5 strata with value/size (1 (4), 2 (4), 3 (4), 4 (4), 5 (4)) -dm_view with the current release (commit 4b9a870af96) DM Object: Generated Mesh 1 MPI process type: plex Generated Mesh 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 (1 (24)) Face Sets: 12 strata with value/size (1 (5), 2 (5), 3 (5), 4 (5), 5 (5), 6 (1), 7 (1), 8 (1), 9 (1), 10 (1), 11 (1), 12 (1)) I believe the older version printed the correct thing? Has something changed in the interpretation of Face Sets? Yes. In the older version, I was only labeling cells, faces, and vertices. There were complaints, so I put in the edge labels. If you check, all the additional labels are on edges, and checking your .msh file, those edges clearly have those labels.
