DMPlexGetHeightStratum
Get the bounds [start, end) for all points at a certain height.
Synopsis
#include "petscdmplex.h"
PetscErrorCode DMPlexGetHeightStratum(DM dm, PetscInt stratumValue, PetscInt *start, PetscInt *end)
Not Collective
Input Parameters
| dm | - The DMPlex object
|
| stratumValue | - The requested height
|
Output Parameters
| start | - The first point at this height
|
| end | - One beyond the last point at this height

Notes
Height indexing is related to topological codimension. Height stratum 0 contains the highest topological dimension
points, often called "cells" or "elements". If the mesh is "interpolated" (see DMPlexInterpolate()), then height
stratum 1 contains the boundary of these "cells", often called "faces" or "facets".
