I'm out of options here. I'm running a simple static analysis on a crankshaft (just imagine a solid round bar). I've created a cylindrical coordinate system. I constrain one end in R, T, and Z as fixed. The other end I apply a 1Nm moment. I've created two measures at points on the end where the moment is applied. One is at 12 o'clock and the other is at 6. The measures are set as rotatonal (radians).
The results are fine and reasonable for everything except the measures and the rotational calculations. See below:

Ultimately I'm trying to compare the rotational stifness between two different shaft designs. Thanks
