DMDAGetAO#
Gets the application ordering context for a distributed array.
Synopsis#
#include "petscdmda.h"
PetscErrorCode DMDAGetAO(DM da, AO *ao)
Collective
Input Parameter#
da - the
DMDA
Output Parameter#
ao - the application ordering context for
DMDA
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.)
Do NOT call AODestroy() on the ao returned by this function.
