Input Parameters#

  • dm - The original DMPlex object

  • overlap - The overlap of partitions, 0 is the default

Output Parameters#

  • sf - The PetscSF used for point distribution, or NULL if not needed

  • dmParallel - The distributed DMPlex object

Note: If the mesh was not distributed, the output dmParallel will be NULL.

The user can control the definition of adjacency for the mesh using DMSetAdjacency(). They should choose the combination appropriate for the function representation on the mesh.
