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 Parameter

	faceVertices	- The face vertices properly oriented
	posOriented	- PETSC_TRUE if the face was oriented with outward normal
