Seems like things have never been better as far as automotive aerodynamic math.
Multi-core processors are routinely taking on the full, 3D Navier-Stokes Equation.
CFD is already so good, ( if you have the time to wait) that it will basically do whatever a full-scale wind tunnel will do. And without dimming the city lights.
If you want to land a manmade satellite on another planet or asteroid, the math is plenty capable.
Computers will only get better, faster.
