DMDANaturalToGlobalEnd#

Maps values from the natural ordering global vector to a global vector in the PETSc DMDA ordering. Must be preceded by DMDANaturalToGlobalBegin().

Synopsis#

#include "petscdmda.h"   
PetscErrorCode DMDANaturalToGlobalEnd(DM da, Vec n, InsertMode mode, Vec g)

Neighbor-wise Collective

Input Parameters#

Output Parameter#

  • n - the global values in the PETSc DMDA ordering

Note#

The global and local vectors used here need not be the same as those obtained from DMCreateGlobalVector() and DMDACreateNaturalVector(), BUT they must have the same parallel data layout; they could, for example, be obtained with VecDuplicate() from the DMDA originating vectors.
