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().
Keywords
distributed array, create, global, distributed, vector
