DMPlexCreateSubmesh#
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 - DMLabelmarking points contained in the surface
- value - The label value to use 
- markedFaces - - PETSC_TRUEif surface faces are marked in addition to vertices,- PETSC_FALSEif 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().
