"Flow around a truck (with wind shield and cargo, street version) at low Reynolds number"

• length of domain: 4.8; height of domain: 1.98
• length of truck: 0.6; height of truck: 0.36; distance to street: 0.06
• 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=50
