CosmosWorks Professional Non-Linear problem.

I have set up a non-linear analysis to simulate a twistingaction on one of our srpings. We took an existing spring andapplied 130 ft-lbs of torque (it rotated about 90 degrees) When Iset up a non-linear anaysis in cosmos and applied the same torqueto a model of the part, it only rotated about 1/3 of the angle...

Can you apply an enforced displacement?

Why are the results so far off... (the scale is set to 1.0)?SolidworksSimulation
