DMDACreateNaturalVector
Creates a parallel PETSc vector that will hold vector values in the natural numbering, rather than in the PETSc parallel numbering associated with the DMDA.
Synopsis
#include "petscdmda.h"
PetscErrorCode DMDACreateNaturalVector(DM da,Vec *g)
Collective
Input Parameter
| da | - the distributed array
|
Output Parameter
| g | - the distributed global vector
|
Note
The output parameter, g, is a regular PETSc vector that should be destroyed
with a call to VecDestroy() when usage is finished.
The number of local entries in the vector on each process is the same
as in a vector created with DMCreateGlobalVector().
