DMClone
Creates a DM object with the same topology as the original.
Synopsis
#include "petscdm.h"
#include "petscdmlabel.h"
#include "petscds.h"
PetscErrorCode DMClone(DM dm, DM *newdm)
Collective
Input Parameter
dm -The original DM object
Output Parameter
newdm -The new DM object
Notes
For some DM implementations this is a shallow clone, the result of which may share (referent counted) information with its parent. For example,
DMClone() applied to a DMPLEX object will result in a new DMPLEX that shares the topology with the original DMPLEX. It does not
share the PetscSection of the original DM.
The clone is considered set up iff the original is.
