Description of the flow problem

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


Description of the spatial discretization

coarse mesh (=level 1): 196 cells, 241 vertices, 1,070
d.o.f.`s

uniform refinements with exact boundary adaption

visualization on level 4: 12,544 cells, 12,904 vertices,
63,440 d.o.f.`s

computational mesh on level 6: 200,704 cells, 202,144 vertices,
1,006,400 d.o.f.`s

nonconforming nonparametric rotated bilinear fem's (meanvalue
version), UPW


Description of the temporal discretization

equidistant time stepping for computation with k=0.01666667

equidistant time stepping for visualization with k=0.05 (= 1
frame)

Total time T=10 corresponds to
600 time steps

fractional step theta scheme
