DMComplexGetConeOrientation
Return the orientations on the in-edges for this point in the Sieve DAG
Synopsis
#include "petscdmcomplex.h"
PetscErrorCode DMComplexGetConeOrientation(DM dm, PetscInt p, const PetscInt *coneOrientation[])
Not collective
Input Parameters
| mesh | - The DMComplex
|
| p | - The Sieve point, which must lie in the chart set with DMComplexSetChart()
|
Output Parameter
coneOrientation -An array of orientations which are on the in-edges for point p. An orientation is an
integer giving the prescription for cone traversal. If it is negative, the cone is
traversed in the opposite direction. Its value 'o', or if negative '-(o+1)', gives
the index of the cone point on which to start.
Note
This routine is not available in Fortran.
