Force Spectrum in Harmonic Response Analysis
I've to model an experimental modal analysis, so i create an harmonic response analysis. I need to apply a "impulse". This impulse is not ideal, so i have to model the frequency spectrum of that, but i don't know how to do that.
I learn that only force can be applied tabular with frequency, but i can't select mesh node as geometry selection or named selection. Opposite, nodal force can be applied to mesh node named selection but i can't write it like a load vs. frequency.
I hope my problem it's clear.
Thanks for any help
