I think something is wrong with the color Byron. Work on it and send
us another if you don't mind.

What do you think is wrong with the color? The colors are in contours so
there are discreet color changes. Each contour is a change of .1 Cp. Other
than that I'm not sure what you mean.

All we got were shades of green Byron which would indicate that
there were no high pressure or low pressure areas at all.
Perhaps the airplane is perfect and is generating no lift.
I guess that is possible in theory. Try putting in several degrees
angle of attack in the program if that is possible.
