Question #695558 on Yade changed: https://answers.launchpad.net/yade/+question/695558
Klaus Thoeni posted a new comment: Yes, most likely the instability comes from numerical rounding errors and the error made by the integration of the equation of motion. Now, you are right. Newton damping is artificial but from my experience a very low value already helps and the dynamic behaviour might not be so wrong after all , unless you are interested of an accurate time scale. Alternatively, you could use viscous or hysteresis damping (or coefficients of restitution). We have the relevant contact models but not sure if they will work with grids and pFacets.
