'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 1 at the left i.e in between X= -10 , Y=-7.5 & X=10, Y=7.7.
• Outflow b.c.'s:  Unknown at the right i.e. in between X=10, Y0-7.5 & 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=10000.

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

  
  
  

• uniform refinements with exact boundary adaption
• visualization on level 5: 32768 cells, 33152 vertices, 164608 d.o.f.`s
• computational mesh on level 5: 32768 cells, 33152 vertices, 164608 d.o.f.`s
• nonconforming nonparametric rotated bilinear fem's (meanvalue version), UPW
