Status: Open => Answered Jan Stránský proposed the following answer: Hello, > Is there a way to access the friction energy dissipation contribution? see [1,2] > and the impact energy dissipation? You have (possibly constant) total energy Etot. You can compute kinetic energy Ekin [3], elastic energy Eel [4], energy dissipated by friction [1,2] The rest is other dissipation Eother. Etot = Eel + Ekin + Efrict + Eother Or you can use O.energy [5,6,7], where you can get other values if Law2 implements it. O.energy also stores artificial dissipation of newton integrator numerical damping. You can compare both approaches :-) > loss by inelastic collisions Note that for your case (only Law2_ScGeom_FrictPhys_CundallStrack), theoretically the only dissipation is only by friction and the numerical damping of newton integrator (there are no true "inelastic collisions") Cheers Jan [1] https://yade-dem.org/doc/yade.wrapper.html#yade.wrapper.Law2_ScGeom_FrictPhys_CundallStrack.plasticDissipation [2] https://yade-dem.org/doc/yade.wrapper.html#yade.wrapper.Law2_ScGeom_FrictPhys_CundallStrack.traceEnergy [3] https://yade-dem.org/doc/yade.utils.html#yade._utils.kineticEnergy [4] https://yade-dem.org/doc/yade.wrapper.html#yade.wrapper.Law2_ScGeom_FrictPhys_CundallStrack.elasticEnergy [5] https://yade-dem.org/doc/yade.wrapper.html#yade.wrapper.Omega.energy [6] https://yade-dem.org/doc/yade.wrapper.html#yade.wrapper.Omega.trackEnergy [7] https://yade-dem.org/doc/yade.wrapper.html#yade.wrapper.EnergyTracker -- You received this question notification because your team yade-users is an answer contact for Yade. _______________________________________________ Mailing list: https://launchpad.net/~yade-users Post to : yade-users@lists.launchpad.net Unsubscribe : https://launchpad.net/~yade-users More help : https://help.launchpad.net/ListHelp
