"Rotor dynamic" uses well-established methods to analyze harmonic vibration in a rotating system. The analysis includes a single rotor, pedestals, bearings and foundations for 6 bearings. The foundation is described with real mode shapes,

The results are:
Unbalance / Force response
Stability analysis (complex eigenvalues)
Modal umbalance sensitivity,
Deformed rotor, (step, bending)
Adjustment of the rotor geometry to measured free-free modes.
