Hi, I have a simple question:

>From which part of the Hertz-Mindlin model is the energy dissipation coming if 
>there is no dissipative force in the model? Can you please refer me to the 
>publication from where this dissipative force appears or from where it comes 
>the  "normDampDissip" in this model? 

I am using: 

    [Ip2_FrictMat_FrictMat_MindlinPhys()],
    [Law2_ScGeom_MindlinPhys_Mindlin()]
    GravityEngine(gravity=(0,0,g))
    
TranslationEngine(translationAxis=[0,0,1],velocity=damp,ids=(all),dead=False,)

For plotting the energy dissipation of the model I am using: 
"Hertz-Mindlin.normDampDissip"

If the system is energy conservative how it happens that we have energy 
dissipation?

Thank you in advance!
