Claim One:
1. A method for generating predicted wind noise within a passenger compartment of an automotive vehicle from a computer aided design (CAD) model representative of the vehicle without use of a wind tunnel, the method comprising the steps of: preparing a CAD model of a desired portion of the vehicle; creating a computational mesh of the desired portion of the vehicle design from the CAD model; computing a transient flow over the desired portion using the computational mesh; extracting a set of aerodynamic data from at least one predetermined area of the desired portion of the CAD model form the transient flow; generating a virtual representation of wind noise at a predetermined location with respect to the CAD model based upon the set of aerodynamic data; and producing an acoustic representation of the virtual representation of wind noise by playing the virtual representation through at least one speaker.
