DMPlexTreeRefineCell

Refine a single cell on rank 0 using the DM’s reference tree, producing a non-conforming mesh

Synopsis

#include "petscdmplex.h"   
/* refine a single cell on rank 0: this is not intended to provide good local refinement, only to create an example of
 * a non-conforming mesh.  Local refinement comes later */
PetscErrorCode DMPlexTreeRefineCell(DM dm, PetscInt cell, DM *ncdm)

Collective

Input Parameters

• dm - The DM with an attached reference tree (see DMPlexSetReferenceTree())

• cell - The cell to be refined

Output Parameter

• ncdm - A new DM in which cell has been split according to the reference tree

Note

This routine is intended for testing and demonstration; it produces one example of a non-conforming mesh but is not a general local-refinement facility. Only rank 0 performs the refinement.
