Your options are the Event Simulation in Fusion or use Inventor Nastran and perform a nonlinear static analysis.</P> Thu, 11 Feb 2021 14:26:06 GMT https://forums.autodesk.com/t5/fusion-design-validate-document/simulation-non-linear-static-unloading/m-p/10075822#M90530 John_Holtz 2021-02-11T14:26:06Z
