Description of the flow problem
-
see the description in
http://www.featflow.de/ture/paper/raschrtu.ps.gz
for the geometrical details
-
inflow b.c.'s: constant with (maximum) velocity 1
-
outflow b.c.'s: natural "do nothing" b.c.'s
-
other b.c.'s: zero velocity at fixed walls
-
initial condition at t=0: starting from fully developed
-
viscosity parameter: 1/nu=10,000
