Hi Rich
regarding the region setting, to adjust the resolution to
3m, use a "-a" flag ('g.region vect=analytical_area res=3
-pa')
also try to set the region, than re-run any previous
steps (like re-import the raster), to be sure that any
operation is being run with the proper region settings.

Can you share the original DEM (before importing to GRASS) so we
can try on different systems?

Not a silly question at all. I tried 'zoom to layer' with no
results.
However, there is a mask for the vector map,
'analytical_area', which is
much smaller the area covered by the DEM. The region is also
set to the
analytical_area map and this might be the issue. Changing the
region to the
raster DEM does not allow the map to display.
While waiting for a solution to the display issue I tried
running r.flow on
the DEM and aspact maps. Grass refused because of a region
resolution
discrepancy between the analytical_area and DEM maps:
DEM resolution: 3 3
analytical_area resolution: 2.99763360 3.00134608
'g.region vect=analytical_area res=3 -p' did not change the
floating point
values to integer 3s.
Thanks,
Rich
