can someone run this through a flow simulator for me?

I tried flow illustrator, but no beans. I waited all day and got nothing.

Here you go :


I downsized the image to 256 pixels wide and expanded the "canvas" of the image for a 256x128 pixel proportion.

Looks like your rear underside is too steep - it looks steeper in the flow simulator drawing than on your drawing too.

And then I measured it and found both to be around 20°

I agree that it looks steeper, so I just double-checked. The angle is correct.

The original image is larger than what Flow-Illustrator likes to consume. It can consume up to 512x256, but I use 256x128 because it's more reliable. That results in an rougher/grainer silhouette.

The rear would be lower in real life. I accidentally ran the bmp up to the bumper, not the hitch. The hitch hangs down lower and would make a good attachment point for mods.

Yeah, the steepness is causing turbulance that is messing with the upper flow.
maybe a small horizontal lip on the bottom to redirect it back ?
