Question #291538 on Yade changed: https://answers.launchpad.net/yade/+question/291538 Status: Open => Answered Jérôme Duriez proposed the following answer: Hi Your problem is quite complex in the sense there is a lot of operations behind what you're doing, and behind the symptoms you're experiencing.. As for the case of particles crossing the wall, several possible reasons could exist: - the interaction between particles and walls is incorrectly defined (does not exist), check for instance the InteractionLoop() - the walls are too thin with respect to the particles' velocity and timestep, such that the particles cross the wall in one time step without having time to "see" the wall (unlikely ?) - your simulation has diverged because of a too great time step with respect to the mechanical properties, "young" parameter specifically. This is the most probable reason from your description, the solution would be to use GlobalStiffnessTimeStepper [*] (if not present in the Engines ?). It is very efficient to compute an adequate time step.

[Yade-users] [Question #291538]: triaxial test:Law2_ScGeom_FrictPhys_CundallStrack
New question #291538 on Yade: https://answers.launchpad.net/yade/+question/291538 Hi all, I have some question about the young modulus in triaxial test using Law2_ScGeom_FrictPhys_CundallStrack. When I increase the particles' young modulus from MPa to GPa, the particle cross the wall and the number of particles decrease. I use the script session-1 to simulate the test and the internalCompaction=false. This is my second time to ask it. So I just describe it simply. This is the original link: https://answers.launchpad.net/yade/+question/291177. Waiting your answers!
