Study of 'Wedge-Shaped'-Hopper with different geometric arrangements

• Wedge shaped domain with hopper angle =40 degrees
• inflow b.c.'s: constant velocity 1 at the top of the hopper
• outflow b.c's: constant velocity at the bottom of the hopper
• Other b.c.'s: zero velocity at the fixed walls
• initial condition at t=0: starting from rest
• viscosity parameter: 1/nu=1,000

• coarse mesh (=level 1): 16 cells, 25 vertices, 96 d.o.f.`s
  

  
  
  

• uniform refinements with exact boundary adaption
• visualization on level 6: 16,384 cells, 16,641 vertices, 82,432 d.o.f.`s
• computational mesh on level 6: 16,384 cells, 16,641 vertices, 82,432 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
