Computational Details:

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

• rectangular domain of height 4 and width 1
• Dirichlet b.c.'s: the parabolic u-velocity profile with maximum value of 1 at the top and at the bottom with maximum 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=5,000

• 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 8: 65,536 cells, 66,177 vertices, 328,960 d.o.f.`s
• nonconforming nonparametric rotated bilinear fem's (meanvalue version), UPW

• equidistant time stepping for computation with k=0.027777778
• equidistant time stepping for visualization with k=0.166666666 (= 1 frame)
• Total time T=200 seconds corresponds to 7,200 time steps
• fractional step theta scheme
