Hi Anton,

you recently changed the visco-elastic law to avoid any attractive force according to Schwager 2007. As a consequence the  effective contact duration and restitution coefficient are not respected relative to the one you set into the material. In other terms, the equations in Pournin 2001 are no longer rightful.

What is your position about this issue ? Do you think that we should implement the equation that Schwager propose (eq. 19) ? (but this equation seems much more difficult to implement than Pournin's one).

Thanks.
