DMPlexGetDepthStratum

Get the bounds [start, end) for all points at a certain depth.

Synopsis

#include "petscdmplex.h"   
PetscErrorCode DMPlexGetDepthStratum(DM dm, PetscInt stratumValue, PetscInt *start, PetscInt *end)
Not Collective

Input Parameters

dm - The DMPlex object
stratumValue - 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".
