PetscErrorCode DMGetDimPoints(DM dm, PetscInt dim, PetscInt *pStart, PetscInt *pEnd)
Collective
Input Parameters#
- dm - the - DM
- dim - the dimension 
Output Parameters#
- pStart - The first point of the given dimension 
- pEnd - The first point following points of the given dimension 
Note#
The points are vertices in the Hasse diagram encoding the topology. This is explained in https://arxiv.org/abs/0908.4427. If no points exist of this dimension in the storage scheme, then the interval is empty.
