I don't understand how a nonlinear force can be applied on the PBUSH card: at least a step force. I can see that you can add a damper and cause the force to change with respect to different things, but not anything about the rotational position. I also looked into CGAP and it seems like it also...
I originally used a CBUSH to create the torsional spring without the gap, but I didn't know that i could define a nonlinear force so I will give it a go. Would I still be able to run it on SOL101?
Helo,
I am brand new to Nastran and Patran so with just a week of experience.
I have been trying to model a loose contact so that once the beam deflects some degrees, then a moment will be created at a pivot point. The magnitude of the moment is dependent on the degrees of defection much like...
