Study of 'Delta Wing in a Square Domain'

• squared domain of length 30
  
• one wing plane is located at x=0, y=0
  
• inflow b.c.'s: constant velocity 1 at the left i.e in between x=-10, y=-7.5 and x=10, y=7.7
• outflow b.c's: unknown at the right i.e. in between x=20, y=-7.5 and x=20, y=7.7
• Other b.c.'s: zero velocity at the fixed walls
• initial condition at t=0: starting from rest
• viscosity parameter: 1/nu=1,0000

• coarse mesh (=level 1): 128 cells, 152 vertices, 688 d.o.f.`s
  

  
  
  

• uniform refinements with exact boundary adaption
• visualization on level 4: 8192 cells, 8384 vertices, 41,344 d.o.f.`s
• computational mesh on level 4: 8192 cells, 8384 vertices, 41,344 d.o.f.`s
• nonconforming nonparametric rotated bilinear fem's (meanvalue version), UPW

• equidistant time stepping for computation with k=0.01
• equidistant time stepping for visualization with k=0.25 (= 1 frame)
• Total time T=30 corresponds to 3,000 time steps
• fractional step theta scheme
