Hi,

Search In the Model Library for the model rotating_blade. This model contains an example of a Campbell diagram.

Thank you Henrik I checkout the problem, and know how to do rotordynamic analysis, but I am more concerned about how to setup simply supported beam boundary conditions at the end of the shaft. The example is of a cantilever beam (Fixed at one end) in my case the ends are supported by bearings (which I assume as simple supports.
