What is Damping Coefficient (%) in dynamic analysis of Creo Simulation? Is it same as damping ratio?

Hi, 

I'm wondering that the value of Damping Coefficient (%) in dynamic analysis is same as Damping Ratio?
If not same how can I find this value? Thank you.

From "Help Center" - "Damping Coefficient (%)": https://support.ptc.com/help/creo/creo_plus/usascii/simulate/simulate/damp_coeff.html

Hi VladimirN,

Thank you for your information. I've read through the Help. I would like to confirm my understand is correct.
As the Damping Ratio expression is

Damping Ratio = Actual Damping Coefficient / Critical Damping Coefficient.

So the Damping Coefficient (%) in Creo Simulate is Damping Ratio * 100

Is my understand correct?
