Anyone Doing/or access To CFD Aerodynamic Modeling?

[windrider919]

Is anyone doing CFD aerodynamic modeling n analysis? I started a thread on the Aerodynamics forum about doing it as a group effort on the multiple vehicles we are modding or wishing to mod but response is weak.

So, if you can do it, could you do it for me?

My question is: Which trailing edge is best for least vortex / drag? Or could a better one be suggested.

Trebuchet has done a lot, but I don't know if he still has access to the software. Since I'm not an engineering student I don't get to play with the fancy stuff. Good old tuft testing will have to do for me

You don't need CFD for that.

V1: Spoilers can be useful if the backlight angle is too steep for attached flow. They create a virtual shallower backlight. I don't think they are optimal.
V2: You could do that too, if the backlight angle would be too steep otherwise.
V3: As long as it's shallow enough all the way back to allow attached flow, that should be fine too.
