Thank you for your this video.
What do you mean by order of magnitude ?

For the input PSD profile, as you mentioned, it is averaged square profile. My question is, I don't see you provide/define the variation of the input profile. Is Ansys having some assumption on the variation level? Thanks!

Thank you for this video. I have a question. I try to get a displacement of a structure in PSD Analysis. Could I use somehow a measured data from acceleration sensor? By means of fast fourirer transformation i got a acceleration in frequency domain (G^2/Hz) in 3 axis . How could I import this data in ansys?

You have to apply the acceleration in each direction using seperate analysis systems..You cant apply load on all three directions in a single analysis system.
So it is,
One for X direction
One for Y direction
One for Z direction
This is because of the probabilistic approach of the PSD analysis.

Or use as Seismic Analysis for Civil engineering.
