      Hello everyone,


      I was wondering why in the modal analysis module I have the possibility to insert loads (such as rotational velocity etc.) even though in this kind of analysis they aren't taken into account. 


      Thank you

      Luis,


      Rotational velocity load is used in Modal analysis to include the gyroscopic effects. 


      From Help:


      For a rotating structure or machine component, the gyroscopic effects resulting from rotational velocities are introduced into the modal system. These effects change the system's damping.


      For a Modal Analysis, Rotational Velocity is valid only when the following Analysis Settings properties are specified:
