Jan Stránský proposed the following answer: thanks, the motivation why to use PBC is clear. Just that they might not reflect the reality in the best way (like failure under uniaxal compression).. The other points I mentioned also may play some role You can try to run several simulations for each size and do some statistics (average and standard deviation). I have tried your script with 10000 and 40000 particles and the results were not "dramatically altered", maybe averaging a few runs would give you better answer that just comparing two individual simulations. If you did it already and the results for different sizes differs a lot, you can be pretty sure that the number of particles is not enough to obtain "steady" results. cheers Jan 2016-10-23 9:53 GMT+02:00 liukeqi <[email protected]>: > Question #403169 on Yade changed: > https://answers.launchpad.net/yade/+question/403169 > > liukeqi posted a new comment: > Hello, > > I want to use YADE to couple with FEM software, just like the > "Multiscale FEMxDEM". > > So I need use YADE model with periodic boundary as an RVE.
