Computational Details:

"Flow around a car at low Reynolds number"

• length of domain: 3.7; height of domain: 1.1
• length of car: 0.8; height of car: 0.24; distance to street: 0.03
• inflow b.c.'s: constant with (maximum) velocity 1 at the left edge and at the upper 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 rest
• viscosity parameter: 1/nu=100
