Question #404455 on Yade changed: https://answers.launchpad.net/yade/+question/404455 feda posted a new comment: Thank you for your suggestions and comments: -using the restitution coefficient instead of cn and cs doesn't change the result. -decreasing the maximum strain rate of periodic cell doesn't change enough the result. Using global damping instead of viscous damping seems the better solution to reach the target porosity in my case! -- 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

Tina Asia is still having a problem:
Hello,
Thanks Jerome and Jan, my code got no error but the upper platen still fixed.
According to Jan's advice, my code got an error and the particle assembly
disintegrated, sub-particles flew here and there. The error is here:

Could you please also provide the .mesh files? without them is it is not possible to test the script.. One more question, what exactly does "can not move" mean? It does not move visually? you checked positions of the particles?..

[Yade-users] [Question #406814]: kinetic energy in Yade
New question #406814 on Yade: https://answers.launchpad.net/yade/+question/406814 Hi everyone, I am now trying to do something with the kinetic energy. What I want to know is the difference between the O.energy['kinetic'] and utils.kineticEnergy() Are they are same? I just found there is a slight difference for the values, e.g. 0.039672285932676854 and 0.03967240895274994. Does the computation have differences? Thank you very much.

Question #406814 on Yade changed: https://answers.launchpad.net/yade/+question/406814 Status: Open => Answered Jan Stránský proposed the following answer: Hello, you can check the source code of kineticEnergy() [1] and as O.energy['kinetic'] [2] is couputed. The formulas used is the same (after a quick look, you may do more detailed investigation if you are interested), however the computation itself **IS** different, so the finite precision of computation and different order of operations may cause different results [3]. How many particles do you have for this computation? cheers Jan [1] https://github.com/yade/trunk/blob/master/pkg/dem/Shop_01.cpp#L180 [2] https://github.com/yade/trunk/blob/master/pkg/dem/NewtonIntegrator.cpp#L40 [3] https://yade-dem.org/doc/formulation.html#result-indeterminism -- 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
