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 on DMDA

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
