Hi,
I am trying to do a frequency response analysis of a solid mechanics problem in frequency domain. There is a boundary load which is sin(w*t), I defined w and t as parameters. W should rotate, so I added rotated coordinate system. For different euler angles,the solution always be zero at each frequency. I tried to obtain resonance frequency of the problem. What can be the missing part; why do I get zero solution everytime?

Thanks for your help.
