Hi Erik,

I had seen this discussion as well. I have a confusion as to what value of frequency we need to give with the damping ratio. 

What I am trying to do here is to find the transient response of a cantilever beam to an intitial displacement. I need to find out the reponse of the beam to different damping scenarios. I have a set of damping ratios (coulomb damping) obtained experimentally. I am tryuing to simulate the condition. So need to conduct thze anlysis for different damping values.
