DMPlexCreateCohesiveSubmesh

Extract from a mesh with cohesive cells the hypersurface defined by one face of the cells. Optionally, a label can 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().
