Extract a hypersurface from the mesh using vertices defined by a label
Synopsis
#include "petscdmplex.h"
#include "petscdmlabel.h"
PetscErrorCode DMPlexCreateSubmesh(DM dm, DMLabel vertexLabel, PetscInt value, PetscBool markedFaces, DM *subdm)
Input Parameters
| dm | - The original mesh
|
| vertexLabel | - The DMLabel marking points contained in the surface
|
| value | - The label value to use
|
| markedFaces | - PETSC_TRUE if surface faces are marked in addition to vertices, PETSC_FALSE if only vertices are marked
|
Output Parameter
subdm -The surface mesh
Note: This function produces a DMLabel mapping original points in the submesh to their depth. This can be obtained using DMPlexGetSubpointMap().
