New question #690020 on Yade:

Dear all,

I found from the previous question that the rolling resistance is implemented in Hertz-Mindlin contact law [1][2][3].
As far as I know, rolling resistance can be defined by the rolling stiffness (Krot) and the coefficient of rolling friction.
My question is although I found that I can define rolling stiffness by [3], I am not sure how to define the coefficient of rolling friction with what parameter? Is the eta [2] refers to the coefficient of rolling friction?

Thanks!
Chien-Cheng
