Default External Incompressible flow Boundary conditions

hi I am not able to figure out boundary conditions for a 3d mesh having a body shell of supermileage car that is to be simulated using fluent 6.1 at 34 m/s of air speed. The general velocity inlet and pressure outlet are leading to divergence in viscous models. Please help at the earliest

Warm Regards Himanshu Almadi Delhi College of Engineering

Please check if u have scaled the model accurately.Which turbulence model u r using? Also check, turbulence properties at inlet and outlet. I feel that vel inlet and pr out shud work.

ramins is on a distinguished road
I want to model an incompressible external flow over a flat plate. whlie I want to set the far-field boundary condition, Fluent gives me a msg that far-field could only be used with ideal gas which is a compressible flow case.
please help me, what should I do to model far-field?
