I want to simulate the effect of crosswinds on a moving vehicle . How do I approach this problem ? I made a CAD model of a simplified car geometry . I then subtracted the geometry from the domain and gave a velocity inlet inclined at an angle to simulate the resultant of the car velocity and the sidewind velocity.
This approach has not yielded favourable results . How should I change my boundary conditions to correctly simulate sidewinds as well as vehicle motion ?

Are there any alternative approaches to solve this problem ?

Any help would be highly appreciated . Thank You .
