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”.
