In this form of modal analysis I wish to find the natural frequency of this body dependent on which cantilever is momentarily statically deflected and released. An example would be what frequency qualities would the body and cantilevers exhibit if the circled end was displaced and released. For reference, the CAD part is a musical comb and I am attempting something similar to this https://blog.kaistale.com/?p=1568, though am unsure if SOLIDWORKS is capable of the same.

I am looking to understand which studies would be used to gauge the resulting frequencies, which would allow for better design of the cantilevers musically, thank you.
