Re: [Yade-users] [Question #706100]: Torque values too low
Question #706100 on Yade changed: https://answers.launchpad.net/yade/+question/706100 Status: Answered => Open Justin is still having a problem: Bruno, Thanks for the reply. All the model parameters are those of actual granular rubber. As far as the contact laws, I have tried all those that would be appropriate (i.e., CundallStrack, MindlinPhys_Mindlin, ViscElPhys_Basic). They all produce similar results. Do you have recommendations or possible common user errors you've seen over the years I should investigate? Note, I also tried creating clumps and polyhedrons: - Clumps can increase the torque, but makes the torque load path erratic - Polyhedrons, results are unknown. Using them does not seem feasible due to computational constraints. Maybe I'm wrong (?), but I just feel density scaling should not be a requirement to produce realistic results.

Question #706100 on Yade changed: https://answers.launchpad.net/yade/+question/706100 Status: Open => Answered Bruno Chareyre proposed the following answer: Hi, > Is this normal DEM behavior? I don't know what "normal DEM behavior" is, so I would say "no". The reason may be that the actual rubber particles interact in ways which you did not account correctly (inappropriate selection of contact model, or inappropriate model parameters). It is difficult to say more without knowing the physical system in details and without knowing how you simulated it.
