Hi Jahnavi,

 

PARAM, G is used to specify damping coefficient which is calculated as 2*Critical damping ratio.

 

Can you explain damping factor of what you want specify?

Hi,

I'm dealing with a skeleton model. so i have to give damping ratio of bones. but damping coefficient means c= 2*damping ratio*omega*natural frequency. Does G represent different parameter here??

G is the Structural damping coefficient.
