DMPlexCreateCohesiveSubmesh
Extract from a mesh with cohesive cells the hypersurface defined by one face of the cells. Optionally, a Label an be given to restrict the cells.
Synopsis
#include "petscdmplex.h"
#include "petscdmlabel.h"
PetscErrorCode DMPlexCreateCohesiveSubmesh(DM dm, PetscBool hasLagrange, const char label[], PetscInt value, DM *subdm)
Input Parameters
| dm | - The original mesh
|
| hasLagrange | - The mesh has Lagrange unknowns in the cohesive cells
|
| label | - A label name, or NULL
|
| value | - A label value
|
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().
