Random vibration analysis in 5.3+

Hello,

I would like to simulate random vibration on a simple beam structure (similar to the documentation example for "Vibration Analysis of a Deep Beam"). Ideally I would like to define the random vibration input as a series of PSD values.

In searching the forums, the most recent replies I could find from a few years ago said that this was not possible in COMSOL yet. Is this still the case? If so, is there some other way to achieve random vibration input without converting to time domain?

Note: I am a total beginner in COMSOL.
