So I have a simulation that involves a 90 degree twist on a block, I have used remote displacement to apply this to my model, however I seem to get a very strange expansion.  It seems to expand one end of my model and only twists it by about 45 degrees.  What could be causing this?

I have other models running these same displacements.  

 

The settings applied to my remote displacement are below

Check if Large Deflection is Off under Solver Controls in Analysis Settings. That would explain it. Large Deflection needs to be On when rotations are large.

Thanks, that was it, I had it turned on for the wrong step
