In this case, the <A HREF="../AO/AO.html#AO">AO</A> maps to the natural grid ordering that would be used
for the <A HREF="../DA/DA.html#DA">DA</A> 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.)
