3D Supersonic flow over a car
 

I'm working on a project about Supersonic flow over a car and I've problem in fluent settings.
I just have the car velocity which is about 447 m/s (Mach=1.3) and I'm using a quarter circle domain
1- How can I set the boundary conditions in fluent (inlet,outlet,symmetry,farfield (curved face) ) ?
2- Can I use pressure solver ?? or just the density based solver ?

Thanks alot
