Mode-Superposition Method is recommended for most dynamic problems due to its speed and ability to cluster results. However, there are specific cases where it cannot be used, such as systems with moderate or significant damping or systems with unsymmetrical matrices – for example, those arising from vibroacoustic or bearing problems. Hence, in such cases, Harmonic Analysis is performed with the Full Method which solves the system matrices directly without relying on mode shapes from modal analysis. This video lesson will discuss cases where it is recommended to use the Full Method for performing a Harmonic Analysis. We have a short lecture followed by a workshop walkthrough example showing how to implement the points discussed.
