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().
