Recently,i am trying to analyze the linear buckling of some kinds of structures.However,When I try to calculate, it always prompts that there are multiple moving coordinate system details in the domain.Could someone help?

This usually means that you have a conflict in a certain domain between a structural mechanics interface using geometric nonlinearity and a moving mesh or deformed geometry. If you look in the Physics and Variables section of the study step, you can resolve the conflict.

In most cases, the underlying cause is a conceptually erroneous modeling.
