Hi Vaclav,

   The simplest way is to check the kinetic energy of the whole granular 
assembly and stop the simulation when the kinetic energy is low enough 
(a given percentage in addition of the lowest kinetic energy computed 
after a long time of simulation without evolution of the loading 
parameters).

   Otherwise something is already implemented for the triaxial test and 
based on the unbalanced force of the particles. But Bruno will speak 
about that better than me!

   Best,

   Luc
