Ratcheting could explain different results between ScGeom and Dem3Dof in PBC. In fact, if one tries the PBC with ScGeom and bool avoidGranularRatcheting=false (it would be true by default) would see that, when the packing reaches a relatively compacted state, kinetic energy would badly increase and unbalanced force as well, due to very high particles rotation. The same situation occurs once using other contact laws in PBC (e.g. HM no-slip) and, again, only if ratcheting is NOT avoided.
Chiara -- TriaxialTest gives different results with ScGeom and Dem3DofGeom, cause is not known https://bugs.launchpad.net/bugs/399963 You received this bug notification because you are a member of Yade developers, which is subscribed to Yade. Status in Yet Another Dynamic Engine: In Progress Bug description: Seems that there is too much friction with the walls, but inspecting the XML file gives nothing suspicious. UnbalancedForce sits constantly at 1.1407 after a small while, without going down. _______________________________________________ Mailing list: https://launchpad.net/~yade-dev Post to : [email protected] Unsubscribe : https://launchpad.net/~yade-dev More help : https://help.launchpad.net/ListHelp
