Airfoil Centroid in Wrong Location #1106
Description
Describe the bug
When we generate Arifoils in 2D and 3D, the value labeled as the "centroid" in code is not actually the centroid. The value labeled "centroid" is actually just the front tip of the airfoil. This makes rotations apply differently in 1-way coupling and incorrect torque calculations in 2-way coupling.
To Reproduce
Load a rotated airfoil
Expected behavior
We expect it to rotate about the center of mass, not the tip
Screenshots
Here is a video of MFC rotatin an airfoil. As can be seen, it rotates around the tip instead of the centroid:
