Physics Models

Hi all

I am student and I am very new to CFD modelling. I am hoping to get some advice from some experienced Engineers.

I have been tasked with a project to determine the Aerodynamic behaviour of a passenger bus. I need to in particular find where boundary layer separation occurs and so on. The current Physics models that I have selected on Star CCM+ are: Steady, 3D Flow
Segregated Flow, RANS
Constant density
K-Omega, SST turbulence model and Gamma ReTheta model.

Are these Models ok for my physics model?
Thank you

Yes I think so. There is not much else you can do.
