Answer:
The model consists of several independent parts. To calculate stability, it is thus necessary to use the "Roots of characteristic polynomial" method of analysis.
Stability Analysis – Eigenvalue Method
I need advice on why I can't calculate mode shapes using the RF-STABILITY add-on module in RFEM 5. The combinations can be calculated, but an error appears during the stability calculation.
