PetscErrorCode PetscPartitionerDMPlexPartition(PetscPartitioner part, DM dm, PetscSection targetSection, PetscSection partSection, IS *partition)
Collective
Input Parameters#
- part - The - PetscPartitioner
- targetSection - The - PetscSectiondescribing the absolute weight of each partition (can be- NULL)
- dm - The mesh - DM
Output Parameters#
- partSection - The - PetscSectiongiving the division of points by partition
- partition - The list of points by partition 
Note#
If the DM has a local section associated, each point to be partitioned will be weighted by the total number of dofs identified
by the section in the transitive closure of the point.
