With which cfd are you comfortable with?

*The big boys say that only a 'full-scale' CFD analysis can reliably predict a realistic outcome of a modification such as this.
*The sophistication of this program requires a supercomputer,as BMW,FORD,Chrysler,GM,Daimler-Benz,etc. possess.
* A single iteration requires almost 2-days of run time.
* Any 'desktop' CFD capability must be viewed as highly dubious.
*If a major automaker presented a peer-reviewed CFD paper,via the annual SAE Congress,they'd have my full attention.

Thanks for the testing.All I could discern was turbulence,which we'd expect in the wake.
