Computational Details:

"Flow around a wing construction at medium Reynolds number (variable angle of attack)"

• diameter of circle: 10
• length/height of (main) wing : 2.2/0.4
• inflow b.c.'s: normalized Dirichlet data (size 1) depending on the angle of attack.
• other b.c.'s: zero velocity at surface
• initial condition at t=0: starting from rest
• viscosity parameter: 1/nu=100,000

• coarse mesh (=level 1): 411 cells, 448 vertices, 2,131 d.o.f.'s
