[petsc-users] Getting the connectivity from DMPlex

[Jian Zhang - 3ME]

Hi Jed,

Thank you very much. I tried to use DMPlexGetCone, but the output is the edge ids, not the vertice ids. For the function DMPlexGetClosureIndices, I can not find it in petsc4py. Do you know any alternative ways to solve this?

Best,

Jian

See DMPlexGetCone or DMPlexGetClosureIndices.
