Description
of the flow problem
- squared domain of length 30
- one wing is located at (0,0) connecting the vertices
(-0.5,0),(0.5,-0.5),(0,0),(0.5,0.5)
- inflow : constant velocity 1 at the left i.e in
between x=-10, y= -7.5 and x=-10, y=7.7
- outflow : unknown at the right i.e. in between x=20, y=
-7.5 and x=20, y=7.7
- Other b.c.'s: zero velocity at the fixed walls
- initial condition at t=0: starting from rest
- viscosity parameter: 1/nu=1,000

39,968 d.o.f.`s
- computational mesh on level 4: 7,936 cells, 8,080
vertices, 39,968 d.o.f.`s
- nonconforming nonparametric rotated bilinear fem's
(meanvalue version), UPW

Description
of the temporal discretization
- equidistant time stepping for computation with k=0.01
- equidistant time stepping for visualization with k=0.25 (=
1 frame)
- Total time T=30 corresponds to 3,000
time steps
- fractional step theta scheme
