[petsc-users] DMPlexGetSupport

[Dharmendar Reddy]

Hello,
          I am seeing an issue using DMPlexGetSupport.

I am trying to get the Ids of cells sharing a given facet in mesh.

I have attached a test code for a small 3 x 3 square mesh. When i print the
support for the 12 facets it has, i see 4 internal facets and 8 boundary
faces, as expected. But the cell Ids are wrong.

 Surcessfully created DM From Cell List
Mesh in 2 dimensions:
  0-cells: 9
  1-cells: 12
  2-cells: 4
Labels:
  depth: 3 strata of sizes (9, 12, 4)
 printing support for facet
 edge id start=          13 edge id end=          24
 f:          13 c:           0
 f:          14 c:           0           1
 f:          15 c:           0           2
