Hello,

I am trying to simulate an experiment where a free-standing body is on a pad. Earthquake ground motion time history is then applied to the pad base. Friction contact in defined between the free-standing body and the pad. This is a Dynamic Explicit simulation.

Is there a way to implement the Coefficient of restitution (COR) in the model? The experiment suggest that the COR is 0.81 (i.e. the ratio of velocity before and after impact).

Thanks.
