DMDANaturalToGlobalEnd
Maps values from the natural ordering global vector to a global vector in the PETSc DMDA ordering. Must be preceeded by DMDANaturalToGlobalBegin().
Synopsis
#include "petscdmda.h"
PetscErrorCode DMDANaturalToGlobalEnd(DM da,Vec g,InsertMode mode,Vec l)
Neighbor-wise Collective on DMDA Many br
Input Parameters
| da | - the distributed array context Many br |
| g | - the global vector in a natural ordering Many br |
| mode | - one of INSERT_VALUES or ADD_VALUES Many br |
Output Parameter
l -the global values in the PETSc DMDA ordering Many br
Many br
Notes
The global and local vectors used here need not be the same as those Many brobtained from DMCreateGlobalVector() and DMDACreateNaturalVector(), BUT they Many brmust have the same parallel data layout; they could, for example, be Many brobtained with VecDuplicate() from the DMDA originating vectors. Many br
Keywords
