Dear all, it is unclear to me what is being flagged with the "marker" flag when a mesh is created using DMPlexCreate. The 2D triangular mesh pictured in the enclosed pdf has the following features:
DM Object: 2D plex 1 MPI process type: plex 2D plex in 2 dimensions: Number of 0-cells per rank: 12 Number of 1-cells per rank: 23 Number of 2-cells per rank: 12 Labels: celltype: 3 strata with value/size (0 (12), 1 (23), 3 (12)) depth: 3 strata with value/size (0 (12), 1 (23), 2 (12)) marker: 1 strata with value/size (1 (20)) Face Sets: 4 strata with value/size (1 (3), 2 (2), 3 (3), 4 (2))
i.e 12 gridpoints, 23 edges and 12 triangular cells. When I call DMGetStratumSize at stratum 0 to 2, this is what I get.
CreateSectionAlternate DMGetStratumSize found0 'marker' points @ depth0 on PE#0 CreateSectionAlternate DMGetStratumSize found20 'marker' points @ depth1 on PE#0 CreateSectionAlternate DMGetStratumSize found0 'marker' points @ depth2 on PE#0
Is the marker flagging boundary edges or boundary vertices (nodes) ? In any case, why are there 20, instead of 10? Finally: I believe face sets refers to boundary faces, where each side of the square domain has been given a different flag. How do I access the face sets information ?
