Hello,
I don't know if the title makes sense. Currently, with a frequency domain analysis I can evaluate steady dynamic response of a system with a set of frequencies for an harmonic load. Instead of sweeping through frequencies I would like to run the study but with this time, loads to which I have set different frequencies.
I tried running a frequency domain analysis with no harmonic load but with instead manual time varying loads (sin) and I get no result. It only produces constant stress and displacement.
In a nutshell I want to run frequency domain analysis in these two cases:
case #1 (already possible): one harmonic load through freqs [1,10,100] Hz
case #2 (target) : two harmonic load at once, with respectively freqs 9Hz and 11Hz.
Has anyone any idea on how to do that?
I must mention that a working example for two loads will need to be extended to up to 50 loads.
Thanks in advance for any tip
