Hi All,

Recently, I'm using this constitutive model (Law2_ScGeom6D_CohFrictPhys_CohesionMoment ) to simulate the cone penetration test[1]. 
when I calculate the inertial number [2] of the sample, I found that the sample belongs to the dense flow regime, which means the simulation is dynamic. 
As we all know that the damping is an important parameter in dynamic simulation. This damping [3] (numerical damping) is not suitable for dynamic simulation. We need s velocity-based damping (it's called viscous damping). 
However, I didn't find any parameters related to the viscous damping. 
###################
If I want to use this constitutive model to simulate the dynamic situation, what should I do? (because I already use this model to calibrate the static triaxial tests.)
#########################

best,
Yong
