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 (reference 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 if the original has been set up.
Use DMConvert()
for a general way to create new DM
from a given DM
