I am doing a frequency response function in SOL 111. I want to define my load and damping as a function of frequency. The load can be a force or a velocity.
But I am unable to do that, I have tried using function, field and excitation function using some tutorials of transient analysis but am unable to do it. If anyone knows how can I define my load and damping as a function of frequency, it would be really helpful.
I just need to keep force and damping constant for now with respect to the frequency. But I am not getting desired results if I just define force and damping simply without defining a frequency function for them.
I would appreciate any help. I have attached some snapshots of some options I tried but failed to use.
