Hi All

I am doing a modal and harmonic analysis

Why aren't the resonance frequencies resulting equal in two cases if I drop the modal solution onto harmonic analysis system and if I don't drop and do the harmonic solution independently from Modal results ?

How are you determining the resonant frequencies?


Kind regards,
Jason
