PETSc version 3.15.5
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

PetscErrorCode DMLocalToLocalEnd(DM dm,Vec g,InsertMode mode,Vec l)
Neighbor-wise Collective on dm
Input Parameters
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.
