DMPlexGetReferenceTree

get the reference tree for hierarchically non-conforming meshes.

Synopsis

#include "petscdmplex.h"   
PetscErrorCode DMPlexGetReferenceTree(DM dm, DM *ref)

Not Collective

Input Parameter

• dm - The DMPLEX object

Output Parameter

• ref - The reference tree DMPLEX object

Developer Notes

The reference tree is shallow copied during DMClone(), thus it is may be shared by different DMs. It is not a topological-only object, since some parts of the library use its local section to compute interpolation and injection matrices. This may lead to unexpected failures during those calls.
