Hi guys,

I'm trying to simulate a shaft with an axisymmetric load. The solver shows me a problem related to fixtures or large displacements, depends on the solver I choose. I use a fixed hinge feature on one side and a roller on the other. Just like a shaft should be hold. I assume that the problem has to do with a turn on the shaft, but the load is axisymmetric so I don't understand why should I restrict the shaft circumferentially.

Is there any way of solving the problem without making a circumferential restriction?

Thank you!!
