It was similar to this one except I could input the diameters. Unfortunatly I lost it when my computer crashed and I had to reload the OS. I'm looking for it will post it if i find it again.

I input the dimensions it gave me the gas flow and approx hp(thrust). didn't really need the hp(a really small number) but the flow rate worked good. The progam gave an animation of the shape and the flow for the designs input.
