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

Notes

If no EGADS model is composed with dm, numCntrlPnts is set to zero and each of the six arrays is set to NULL.

The same holds for any individual output that has no composed data in the dm.

All the arrays have a length of numCntrlPnts.

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.
