DMGetDimPoints#

Get the half-open interval for all points of a given dimension

Synopsis#

#include "petscdm.h"          
#include "petscdmlabel.h"     
#include "petscds.h"     
PetscErrorCode DMGetDimPoints(DM dm, PetscInt dim, PetscInt *pStart, PetscInt *pEnd)

Collective

Input Parameters#

  • dm - the DM

  • dim - the dimension

Output Parameters#

  • pStart - The first point of the given dimension

  • pEnd - The first point following points of the given dimension

Note#

The points are vertices in the Hasse diagram encoding the topology. This is explained in https://arxiv.org/abs/0908.4427. If no points exist of this dimension in the storage scheme, then the interval is empty.
