Description of the flow problem
-
wedge shaped domain with half-angle 30 degrees
-
inflow b.c.'s: constant velocity 1 at the top of the hopper
-
outflow b.c's: constant veloctiy at the bottom of the hopper
-
Other b.c.'s: zero velocity at the fixed walls
-
initial condition at t=0: starting from rest
-
viscosity parameter: 1/nu=1,000
