Here I meet a problem about the damping modal in Workbench (ANSYS 18) .
how does the software calculate the stiffness coefficient ? I have found some guidance in this link but the result is not correct.
I follow this public essay and I want to redo what he has done. But he only give the parameter above so I have a doubt that the parameter is enough to calculate.
Hopefully I can get your guidance!
Thanks all guys!

Damping ratio is mode dependent. You could try approximating it via the stiffness and mass coefficient. Please see here for some documentation.

But I also need to calculate the parameter using Damping Ratio so that I can calculate the stiffness and mass coefficient. So here the problem is still about the frequency the Ansys defined.Because the frequency above is a range of frequency but not a specific number.
