[petsc-users] difference in Face Sets in latest petsc release

[Sharan Roongta]

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

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

  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.


  Thanks,


     Matt
