Sergei,
I agree with cfg83, a diagnosis of one vehicle cross sections that was a good example of how a person could improve it's aerodynamics, by the author of Flow Illustrator would be wonderful.
That way you get a chance to teach us how to use your program properly, without us bogging you down explaining "again and again".
If you picked a sample car and gave one of us the proper recipe we could even run all the examples and set up the videos on Youtube etc. Then you would be free to concentrate on how you want to write it up and post it.
If you selected a car that someone has real world data on with heavy aero mods like basjoos, AndrewJ's or MPGmetro's we could tie the simulation directly to the real world.
The question is where to "concentrate" the data... that is for a moderator to figure out
but it sure would be a wonderful resource to have an article on Flow Illustrator
as for Aero without math
most things are more enjoyable without math, aero particularly so
