New question #253626 on Yade: https://answers.launchpad.net/yade/+question/253626
Hello all, I wish that i have the answer because i want to understand . So, i want to use the constituve law for the Hertz-Mindlin formulation. And i want to use a non linear damping in both the normal and tangential direction. So the problem is : when i specify "en" and "es" in my script like InteractionLoop( [Ig2_Sphere_Sphere_ScGeom(),Ig2_Facet_Sphere_ScGeom()], [Ip2_FrictMat_FrictMat_MindlinPhys( en=0.1,es=0.2)], [Law2_ScGeom_MindlinPhys_Mindlin()] ) I create a linear or a non-linear viscous damping!!! Really i'm confused , because when i read ( https://github.com/yade/trunk/blob/master/pkg/dem/HertzMindlin.cpp https://github.com/yade/trunk/blob/master/pkg/dem/HertzMindlin.hpp ) I find two meaning , one time you tell that when I specify "en" and "es" , automatically betan and betas will be computed from the formulation and this means that a linear viscous damping will be used . on the other hand , you tell that when i specify en or es alpha will be computed and this means that we use a non-linear viscous damping . Thanks a lot for help .
