DMDAGlobalToNaturalEnd

Maps values from the global vector obtained with DMCreateGlobalVector() to a global vector in the natural ordering. Must be preceded by DMDAGlobalToNaturalBegin().

Synopsis

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

Neighbor-wise Collective

Input Parameters

• da - the DMDA context

• g - the global vector, see DMCreateGlobalVector()

• mode - one of INSERT_VALUES or ADD_VALUES

Output Parameter

• n - the global values in the natural ordering, see DMDACreateNaturalVector()

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.
