Hey guys, i'm new in CFD..
I'm gonna do a 2D simulation of a car aerodynamic, is there any standard dimension of the domain that i have to choose? i mean the length in front of the car and behind the car.. is there any exact dimension for that simulation?
any answer will be helpful, thank you..

You should extend your domain upstream, downstream and spanwise to ensure your boundaries do not affect your simulation. Have a read of this post (use the search function to read other suggestions).
