Hi Adriano,

Thank you very much for sending the example file. Do you have any Rotordynamics User Guide pdf copy or training material, please send the link to me. 

I wish to do rotordynamics frequency response analysis and transient response also.

Thank you very much for your help.

With regards,

Chandra
