I'd started a plan-view drawing,then got distracted digging for other plan views to homogenize into some sort of generic form.

One size fits all sounds to me like a tall order.

That's where I'm hoping good-enough CFD can help. Even without turbulent boundary perfection my hope is that pressure and flow balance as a function of roof/side taper aggression can be compared. In the case of an aerocap for a pickup, for example, the cab and box fixed geometries no doubt limit how much streamlining can be done.

Progressing to the rear,begin to roll the sides into progressively steeper tumblehome ( as we see in the HONDA Fit B,C,and D-pillars),blending into the roof-line with slowly increasing radii.(extremely difficult to fabricate!).

That was a design goal for me when I drafted a concept cap.

Focusing on your own priorities is completely understandable, Phil. It's too bad the weather was sh*t when I visited last month. For future reference next time I'd be happy to lend a hand wherever I can. Tuck the offer in your back pocket for consideration.
