DMPlexGetDepthStratum#
Get the bounds [start, end) for all points at a certain depth.
Synopsis#
#include "petscdmplex.h"   
PetscErrorCode DMPlexGetDepthStratum(DM dm, PetscInt depth, PetscInt *start, PetscInt *end)
Not Collective
Input Parameters#
- dm - The - DMPLEXobject
- depth - The requested depth 
Output Parameters#
- start - The first point at this - depth
- end - One beyond the last point at this - depth
Notes#
Depth indexing is related to topological dimension.  Depth stratum 0 contains the lowest topological dimension points,
often “vertices”.  If the mesh is “interpolated” (see DMPlexInterpolate()), then depth stratum 1 contains the next
higher dimension, e.g., “edges”.
