Please try to increase number of iterations to several hundred, run
it without -t
and run it on something smaller (1000x1000) - it looks like it did
not get
too far when it finished the computation, but it should have given
you at least
a warning or error message (it might have run out of memory).
I need to try it out, I still run it in older versions of GRASS64,

From a previous post I realize r.terraflow isnt working in 6.4
yet.., so
thought I would try a dumbed-down-DEM with r.sim.water ... DEM, mask,
slope, aspect, etc look good; everything seem to run, but...no
outputs
are generated.... hmmm...?
( I can take this to users' list if this is the wrong place, but
seems a
lot of things are in motion here...)
thanks in advance!
