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 DMPLEX object

• 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”.
