Hi Fabio,


You can look at the code to see how the threshold is calculated [1], but
it's basically the value you define in CohFrictMat * r^2, which in your
case is 10. Applying 5+5 makes 10 (note that you are doing a dynamic
calculation, the force will oscillate between 0 and 10, plot the force
and you will see it). Now, I would suggest you fix one node and apply a
velocity at the other node and plot displacement vs normalForce in the
interaction, i.e. replace eps with fN =
