Description of the flow problem
- squared domain of length 30
- one heated circle of radius 1.5 and located at x = 0, y
=02
- inflow b.c.'s: constant velocity 1 at the left bottom edge
i.e in between x=-10, y=-7.5 and x=10, y=7.7
- outflow b.c's: unknown at the right top edge 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

Description of the spatial discretization
- coarse mesh (=level 1): 116 cells, 137 vertices, 628
d.o.f.`s
- uniform refinements with exact boundary adaption
- visualization on level 4: 7424 cells, 7592 vertices,
37,456 d.o.f.`s
- computational mesh on level 4: 7424 cells, 7592 vertices, 37,456 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
