When you do a 'clean' profile flow analysis the meshing wipes out the solid body basically (the whole car gets sliced!). All is left is the layer you want to analise (aka a sheet). Now, I took the center line of the car for forum entertainment purposes but you can actually slice this with nano size precision where ever you want in X,Y,Z directions. I couldn't upload them all so took the center line of the flow (generic). So that is why the fenders are a tad weak looking.

The black hole in the middle is then filled up manually with the boxster outline using Photoshop. That is for Markus and Al' to enjoy a representation of the car (well, he didn't LOL). Just more pleasant to look at than a "black hole".

If you don't slice up your plot, this is basically what it looks like. The car is in there somewhere that Virtual Wind Tunnel box. Can output billions of layers with that thing but normally the center line is pretty accurate and sufficient for presentation purposes.

Hope you understand a bit better now. All very geaky huh

(but fun stuff, scout promise lol)

@Nine8six: seems all pretty easy – if you compare it with a tourbillon wrist watch.

I would say the 996 (cw: 0,27/cwa: 0,54) is better than a 2003 986 S (cw: 0,32/cwa; 0,617)

But i think Dr. Yang Proshche has better measurement methods than me. So let's see what will happen.

And cool wallpapers are made by manually 'seeding' the wind tunnel with lines. As many as you want, where ever you want them to flow (hood, fenders, under the car, whatever).

Represents the traditional 'Smoke' flow lines if you prefer.

There you go! You guys know how to do this stuff! Very very easy (not lolll)
