DMPlexGetOrientedFace#

Given a cell and a face, as a set of vertices, return the oriented face, as a set of vertices, in faceVertices. The orientation is such that the face normal points out of the cell

Synopsis#

#include "petscdmplex.h"    
#include "petscdmlabel.h"   
PetscErrorCode DMPlexGetOrientedFace(DM dm, PetscInt cell, PetscInt faceSize, const PetscInt face[], PetscInt numCorners, PetscInt indices[], PetscInt origVertices[], PetscInt faceVertices[], PetscBool *posOriented)

Not Collective

Input Parameters#

  • dm - The original mesh

  • cell - The cell mesh point

  • faceSize - The number of vertices on the face

  • face - The face vertices

  • numCorners - The number of vertices on the cell

  • indices - Local numbering of face vertices in cell cone

  • origVertices - Original face vertices

Output Parameters#

  • faceVertices - The face vertices properly oriented

  • posOriented - PETSC_TRUE if the face was oriented with outward normal
