DAGetGlobalVector
Gets a MPI PETSc vector that may be used with the DAXXX routines.
Synopsis
#include "petscda.h"
int DAGetGlobalVector(DA da,Vec* g)
Collective on DA
Input Parameter
da -the distributed array
Output Parameter
g -the global vector
Note
The output parameter, g, is a regular PETSc vector that should be returned with
DARestoreGlobalVector() DO NOT call VecDestroy() on it.
VecStride*() operations can be useful when using DA with dof > 1
Keywords
distributed array, create, Global, vector
