It's fully functioning.
The bournelli effect can be seen clearly.
The shape compresses air slightly below the wing.
It also decompresses the air above the wing.
This causes the air to flow more quickly over the top of the wing.
This is called the bournelli effect, and it describes how flowing fluid has less pressure than the surrounding fluid.
The higher pressure under the wing pushes up on the wing to try and equalize the pressure.
The wing harvests this force as lift.
Note:
I have set up 2 force springs, to read a relative output between drag and lift. It's quite a nice ratio (about 1:5 drag:lift)
OH YEAH! One last thing!
Be sure to turn off the smooth surface water, so you can see the water patterns!
