Hello Nejib,

I think you'll have to precise your question. The trajectory of a 
particle during a simulation is directly computed by Yade : that's its 
aim, I would say ! It depends indeed on the sum of the forces acting on 
a particle, which you can have in python with

O.forces.f(id of the particle you want to consider)

It returns you the corresponding vector (and O.forces.t for the 
resulting torque)
