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
Notes#
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()
.
