Hi there, I'm running the simulation with a vibration profile that encompasses from 20-2000 Hz. I am probing a certain node on my model to obtain the acceleration response plot to obtain a PSD profile.

But the profile obtained falls short of 2000 Hz. The PSD value stops at, for example: 1400 Hz. 

Does anyone know what parameter I should change for this?
I think it might have to do with the number of frequency
