Computational Details:

"Flow in a Lid Driven Cavity at low Reynolds number"

• stationary 2D "lid driven cavity" flow
• squared domain of length 1
• Dirichlet b.c.'s for the u-velocity at the top: u=1 for y=1
• other b.c.'s: zero velocity elsewhere for u and v
• initial condition at t=0: starting from rest
• viscosity parameter: 1/nu=5,000

• coarse mesh (=level 1): 53 cells, 72 vertices, 301 d.o.f.`s
  

  
  
  

• uniform refinements with exact boundary adaption
• visualization on level 5: 13,568 cells, 13,857 vertices, 68,416 d.o.f.`s
• computational mesh on level 7: 217,088 cells, 218,241 vertices, 1,087,744 d.o.f.`s
• nonconforming nonparametric rotated bilinear fem's (meanvalue version), UPW

• equidistant time stepping for computation with k=0.03333334
• equidistant time stepping for visualization with k=0.1 (= 1 frame)
• Total time T=50 corresponds to 1,500 time steps
• fractional step theta scheme
