Sal Rodriguez a nuclear engineer at Sandia National Labs came up with software where you input:
1: Your shape. (eg: car body)
2: The 'fluid' (air) its moving through.
3: The speed at which its moving through the 'fluid'
And it outputs the optimal ...er... 'Dimplage' for your car etc for you!
eg:
The so dimpled nose cone of a rocket averaged
22% less frictional drag. (peak: 39.1%)

This is most likely the software the dimpled piston crowd (linked below) got their grubby mits on!

I would guess that said software would be much sought after here.
I have not (yet) found such and doubt if Sandia puts it up for download all over their site,
