The following is just my opinion and to be taken as just that.
I understand the extreme limitations of this program. I can basically use a cardboard cutout, non-3D version of something and get a jist of what's going on. Just a sliver down the middle. There are lots of dynamics with flow from so many angles that this program can't show that would greatly affect this sliver of a flow. But I think I can use this as a tool along with independent experiments to help visualize a path to take.
Tuft testing is great for near-car wind flow dynamics, but this program makes me realize even more the importance of flow going on 10 feet or more behind me. Tuft testing with 10 foot streamers behind the vehicle ought to be added to any aero experiments along with near-car tuft testing. It would sure be cool to see if the aero experiment resulted in even flow past the vehicle or if it resulted in a worse situation.
