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 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().
