We have to be careful about what the flow simulator shows. It may mislead us or we (I) may enter the wrong defaults (
garbage in, garbage out) and throw off the calculation. While it demonstrates *principles*, the author does not claim real-world results.

I would be gratefull for your comments, as this may improve Flow Illustrator. If, say, the functionality of it is fixed, what can be improved?
Another thing: I read all the posts, and, rather naturally, the level of the background knowledge of aerodynamics and CFD (Computational Fluid Dynamics) issues, well, varies. I would be happy to explain things, but there is just no way to explain aerodynamics in one sitting, and it would be nice not to need to repeat the same explanations again and again. May be I should concentrate them somewhere. Would there be much interest, do you think, to something like 'Aero without math' blog (run by a professor of the Department of Aeronautics of the Imperial College London, which, as you surely know, is one of the best universities in the world :-))?

Question: Could we be looking at the origin of the "dropped tailgate" theory? I mean, maybe it does work for the few trucks that can drop their tailgate and get an 11-13 degree drop from the rear of the "cab roof" to the end of the opened tailgate.
