DMDAGetAO
Gets the application ordering context for a distributed array.
Synopsis
#include "petscdmda.h"
PetscErrorCode DMDAGetAO(DM da,AO *ao)
Collective on DMDA
Input Parameter
da -the distributed array
Output Parameters
ao -the application ordering context for DMDAs
Notes
In this case, the AO maps to the natural grid ordering that would be used
for the DMDA if only 1 processor were employed (ordering most rapidly in the
x-direction, then y, then z). Multiple degrees of freedom are numbered
for each node (rather than 1 component for the whole grid, then the next
component, etc.)
Keywords
distributed array, get, global, indices, local-to-global
