| dm | - The non-overlapping distributed DMPlex object | |
| overlap | - The overlap of partitions (the same on all ranks) |
| sf | - The PetscSF used for point distribution | |
| dmOverlap | - The overlapping distributed DMPlex object, or 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.
