Computational Details:

"(Regularized) Driven Cavity (III) at medium Reynolds number (height 2, width 1 of the cavity)"

• rectangular domain of height 2 and width 1
• Dirichlet b.c.'s for the u-velocity at the top (parabolic with maximum value of 1) and at bottom (parabolic with minimum value of -0.5)
• other b.c.'s: zero velocity at fixed walls
• initial condition at t=0: starting from rest
• viscosity parameter: 1/nu=20,000

• coarse mesh (=level 3): 32 cells, 45 vertices, 184 d.o.f.'s
  

  
  
  

• uniform refinements with exact boundary adaption
• visualization on level 7: 8,192 cells, 8,385 vertices, 41,344 d.o.f.`s
• computational mesh on level 9: 131,072 cells, 131,841 vertices, 656,896 d.o.f.`s
• nonconforming nonparametric rotated bilinear fem's (meanvalue version), UPW
