DMPlexGetGeomCntrlPntMaps#

Gets arrays which maps Control Point IDs to their associated Geometry FACE, EDGE, and VERTEX.

Synopsis#

#include "petscdmplex.h"   
PetscErrorCode DMPlexGetGeomCntrlPntMaps(DM dm, PetscInt *numCntrlPnts, PetscInt **cntrlPntFaceMap, PetscInt **cntrlPntWeightFaceMap, PetscInt **cntrlPntEdgeMap, PetscInt **cntrlPntWeightEdgeMap, PetscInt **cntrlPntVertexMap, PetscInt **cntrlPntWeightVertexMap)

Not collective

Input Parameter#

dm - The DMPlex object with an attached PetscContainer storing a CAD Geometry object

Output Parameters#

numCntrlPnts - Number of Control Points defining the Geometry attached to the DMPlex
cntrlPntFaceMap - Array containing the FACE ID for the Control Point. Array index corresponds to Control Point ID.
cntrlPntWeightFaceMap - Array containing the FACE ID for the Control Point Weight. Array index corresponds to Control Point ID.
cntrlPntEdgeMap - Array containing the EDGE ID for the Control Point. Array index corresponds to Control Point ID.
cntrlPntWeightEdgeMap - Array containing the EDGE ID for the Control Point Weight. Array index corresponds to Control Point ID.
cntrlPntVertexMap - Array containing the VERTEX ID for the Control Point. Array index corresponds to Control Point ID.
cntrlPntWeightVertexMap - Array containing the VERTEX ID for the Control Point Weight. Array index corresponds to Control Point ID.

Note#

Arrays are initialized to -1. Array elements with a -1 value indicates that the Control Point or Control Point Weight not associated with the referenced Geometric entity in the array name.
