DMPlexSetAdjacencyUser - Define adjacency in the mesh using a user-provided callback

Input Parameters:

+ dm - The DM object

. user - The user callback, may be NULL (to clear the callback)

- ctx - context for callback evaluation, may be NULL

Level: advanced

Notes:

The caller of DMPlexGetAdjacency may need to arrange that a large enough array is available for the adjacency.

Any setting here overrides other configuration of DMPlex adjacency determination.

Collective on dm

1553

1554

Input Parameter:

1555

+ dm - The original DMPlex object

1556

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

1557

1558

Output Parameter:

1559

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

1560

- dmParallel - The distributed DMPlex object

1561

1562

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