Computational Details:

"Flow around `STEVE' (Stephan Braig) at high Reynolds number"

• diameter of the circle: 2
• rotational speed 1 (counterclockwise) on the circle (tangential speed)
• other b.c.'s: zero velocity at the characters
• initial condition at t=0: starting fully developed
• viscosity parameter: 1/nu=1,000,000

• coarse mesh (=level 1): 57 cells, 95 vertices, 369 d.o.f.'s
  

  
  
  

• uniform refinements with exact boundary adaption
• visualization on level 5: 14,592 cells, 15,260 vertices, 74,304 d.o.f.`s
