Computational Details:

"Flow around a truck (without wind shield and cargo, `flying' version) at medium Reynolds number"

• length of domain: 4.8; height of domain: 3.6
• length of truck: 0.6; height of truck: 0.30
• inflow b.c.'s: constant with (maximum) velocity 1 at the left edge and at the upper and lower wall
• outflow b.c.'s: natural "do nothing" b.c.'s
• other b.c.'s: zero velocity at fixed walls
• initial condition at t=0: starting from fully developed
• viscosity parameter: 1/nu=100,000

• coarse mesh (=level 1): 460 cells, 508 vertices, 2,396 d.o.f.`s
  

  
  
  

• uniform refinements with exact boundary adaption
• visualization on level 4: 29,440 cells, 29,824 vertices, 147,968 d.o.f.`s
