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.

This is "in theory"...potential flow theory :) I think the variations in
color are just hard to see. This is the same model as before with the
contours outlined. Does this make more sense? This is 4 deg AOA. 0.136
Mach number. BTW the tips of the wings and tail aren't closed which is why
you see strange low pressure areas out toward the tips.

Byron

Yes it does. This is the bottom plot. The yellow area under the wing was the high
pressure I was speaking of.
