Spring-dashpot contact model

Hi François,
There is an infinite number of spring-dashpot models. Could you be more specific?

According to your private email, you want Kelvin–Voigt model.
It should be here:
https://yade-dem.org/doc/yade.wrapper.html#yade.wrapper.Law2_ScGeom_ViscElPhys_Basic

I'm not personally vouching for it. Let us know if it gives satisfying results, it will help filling this: https://www.yade-dem.org/wiki/ConstitutiveLaws

Bruno,

Can you confirm me that the tangential component of this force law is taken as the minimum
 between a term corresponding to tangential elasticity (controlled by ks) and a term corresponding
 to the Coulomb law of dynamic friction for oblique sliding impacts (see for instance J.Schafer, S.Dippel and D.E.Wolf,
J. Phys. I, 6 (1996) 5-20).
Do you have examples where this law that you mentioned has been used

Francois

As said above, I can't confirm anything François (note that the law is red on the wiki page).
You should check the code if something is not explained in the documentation.
