The goal of the simulation is to compute the velocity- and pressure-distribution over a carbody, the car travelling at 25 [m/sec] or 90 [km/hour]. You will find that

• Once you have etsblished the suface model of the carbody, the rest of the task is fairly simple.
• The solution time of 17 seconds on a standard PC is relatively short.
• To get acceptable results, one has to model the road surface as well.
• The results are in excellent agreement with the averaged results computed with industry standard Navier-Stokes Solvers.

The model could very well have been expanded to include a stability analysis of the car, accounting for tyres, wheel-suspension, and other factors.
