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 surfacevalue - 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()
.
