Hello Dlooman,

I have already tried to create an acceleration in the modal applied to the body I want using CMACEL,BODY1,9.81,9.81,9.81 and then use LVSCALE,1 in the Random vibration to apply the PSD. However, I obtained results as 0.

Looking at the solution information I saw that it interprets that all the participation factors are 0 when they are not.

How could I do this?
