Why particles didn't stop moving (Like vibrating) in "Kinetic Energy"

After a certain time, the particles is like start moving again (like vibrating). And for this my geometry "IMPACT BODY" never stop to acumulate Normal Cumulative Force.

    Hi Luis, how long did you run the simulation for?  I ran the simulation but changed the factory.  The factory was set to create 500 particles/s which is too high a rate for the area making the simulation especially slow.  Reducing the rate and limiting the number of particles to create runs much faster and by 10 s the simulation was stable. 


    Potentially originally it was still introducing material to the simulation?

    Hi, Stephen.

    I was running by 10 s, and using the model "Relative wear".

    The main focus of this study is to compare energy absortion or force adsortion using diferents materials (Like steel and rubber in my Zip).

    I notice that in certain time the "Normal Cumulative contact energy" reaches a maximum value and stops, but in the case of "Normal Cumulative force" never stop to increase.

    I also change the friction model to "Tipe C rolling friction"

    So, if I am doing this study, in wich cases is ok using contact energy and Cumulative force to compare materials absortion

    Thanks
