Hi,

I am trying to make a simple model of some springs in series configuration. I am using CohFricMat to create bonded particles. My problem is that I cannot define viscous damping when I use Law2_ScGeom6D_CohFrictPhys_CohesionMoment. I know this functor does not use velocity based damping. So I have to use numerical damping, which is not suitable for dynamic simulation (based on what I understood). Could you help me how I can have a simple model of a few bonded particle with viscous damping? ( I am trying to see free vibration of mass and spring system in configuration series) 

Thanks,
Reza.
