Question #238696 on Yade changed: https://answers.launchpad.net/yade/+question/238696
Bruno Chareyre posted a new comment: Reflecting contact damping in time-step determination is relatively easy in the context of GlobalStiffness (though not implemented). The derivation has been explained by Emanuele Catalano (page 59 in [1]). For Emanuele it was fluid viscosity instead of contact viscosity, but the equations are similar if you replace V (eq. 4.9) by a global viscosity matrix reflecting existing contacts on a given body. For the record, Cundall's non-viscous damping [2] is not modifying the timestep (but it should not be used for impact problems).
