Random Vibration PSD Force

Workbench has implemented the most common forms of PSD input. Acceleration, Velocity and Displacement are common because vibration is usually measured using an accelerometer. How did you end up with a Force PSD?
To use a Force PSD in Workbench, you have to use a Command object.
Look up the command PSDUNIT.
Use Type = FORC

Ah, okay, I thought you were asking about Inputs, which I answered. You want to know about Response PSD output like the one for relative acceleration that I show below.
You want to know if you can plot a Response PSD for Force. I don't think so. Maybe someone else will comment.
I know you can obtain the 1 sigma value of the Reaction Force at the Fixed Support.
