Hello all,

My question is regarding the time stepper for different models. Now YADE has the time stepper for elastic and viscoelastic models [1]

My model is like viscEL but the spring (Kn and Ks) and the dashpot (Cn and Cs) are nonlinear. The problem is with the dashpot (the material is much more viscous than elastic), as the rheological's coefficient changes with the overlap volume I have to use time stepper. Is it possible to relate my model with the existent ones [1]? Is it possible to change the rheological's coefficient each time step inside [1]? . How do I load the values?

Thanks a lot,
Ricardo.
