I want to simulate the 3d flow over a prototype car to obtain the value of Cd in low velocity, say 25 km/h (about 7 m/s). May I assume that the ground is not moving, so I just simulate the air flow with that velocity and the car and ground is standing still. With that low velocity, no need for me to simulate turbulent. am I right?
Hmm.. should I estimate the boundary layer thickness first to set the smallest grid?

THank you for ur answer.
