Hi everybody,

I've to model an experimental analysis, so i create an harmonic response analysis. I need to apply a "rotation". This rotation value is 1100 rpm, so i have to model the frequency spectrum of that, but i don't know how to do that.

I learn that only rotational force can be applied in harmonic response, but i can't select node as geometry selection or named selection. Also, i had do the nodal displacement, but i cant do the named selction as required.

I hope my problem it's clear.

Thanks for any help

Regards.
