DMLocalToLocalEnd

 Maps from a local vector (including ghost points that contain irrelevant values) to another local vector where the ghost points in the second are set correctly. Must be preceded by DMLocalToLocalBegin().

Synopsis

#include "petscdm.h"     
PetscErrorCode  DMLocalToLocalEnd(DM dm,Vec g,InsertMode mode,Vec l)
Neighbor-wise Collective on DM and Vec

Input Parameters

da - the DM object
g - the original local vector
mode - one of INSERT_VALUES or ADD_VALUES

Output Parameter

l -the local vector with correct ghost values

Notes

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

Keywords

DM, local-to-local, end
