I think what we are seeing is a conflict of interest

. I want to share my thoughts partly to give people a nudge in the right direction. Partly so that more knowledgeable people will correct me when I am wrong about something. But there are two reasons why I am holding back slightly:
1. I don’t think anyone wants the solutions to be “formulaic”. We all want to see creative solutions to these problems.
2. The obvious one, I want to win. I am going to keep some ideas private.

"Looking at CFD Plot "X", there is a "Y" coloured patch [here], this indicates that "Z". You should change geometry "A" to rectify this".
The example you give is sort of correct, but I think that an:
if x then y approach is too simplistic. Yes, you could definitely decrease the slope in the central region to a point where there was no longer stall. But if you look at the cars from the last race: WB, variante, Mercury, JJR, CAEdevice and me have all seemingly arrived at the same conclusion: Inject fresh air into the diffuser. Work the fresh air instead of the separated bubble. This solution is hard to draw from a simple
if x then y.
I am not saying this is the optimum solution, in fact I can think of a potentially better solution in this area that this basically “blocks”. I think in general it is more useful to clarify the actual problem, and make competitors come up with their now solutions.
My point is: pointing to the problem is more interesting than suggesting a solution. There are "universal truths" but they are basically: stalling is bad, don't let the rad exhaust hit the rear wing, etc.
Are you going to continue this “series” with front and rear wing? I think you may have started with the hardest one!

If there are CFD plots that would be more useful in the diagnosis of problems, that aren't already in the package Andre sends over, what would be more useful? If anyone can name them I'll see if Andre could add them.
LIC! Line integral convolution everywhere! I think everyone should be looking at LIC slices.
