DMPlexRestoreTransitiveClosure#

Restore the array of points on the transitive closure of the in-edges or out-edges for this point in the DAG

Synopsis#

#include "petscdmplex.h"   
PetscErrorCode DMPlexRestoreTransitiveClosure(DM dm, PetscInt p, PetscBool useCone, PetscInt *numPoints, PetscInt *points[])

Not Collective

Input Parameters#

  • dm - The DMPLEX

  • p - The mesh point

  • useCone - PETSC_TRUE for the closure, otherwise return the star

  • numPoints - The number of points in the closure, so points[] is of size 2*numPoints

  • points - The points and point orientations, interleaved as pairs [p0, o0, p1, o1, …]

Note#

If not using internal storage (points is not NULL on input), this call is unnecessary
