Computational Details:

"(Regularized) Driven Cavity (I) at medium Reynolds number (height 4, width 1 of the cavity)"

• rectangular domain of height 4 and width 1
• Dirichlet b.c.'s (parabolic with maximum value of 1) for the u-velocity at the top
• 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): 64 cells, 148 vertices, 360 d.o.f.`s
  

  
  
  

• uniform refinements with exact boundary adaption
• visualization on level 6: 4,096 cells, 4,257 vertices, 20,800 d.o.f.`s
• computational mesh on level 9: 262144 cells, 263425 vertices, 1,313,280 d.o.f.`s
nonconforming nonparametric rotated bilinear fem's (meanvalue version), UPW
