Christian Jakob posted a new comment: > 2), we insert particles into the box, usually 8000~10000, I have estimated the mean particle size used in yade, usually 20-40mm in average, a bit lager than the usually sand particle size 0.5mm -1mm. A box composed of particles a bit larger than the sand grains used in real experiment could It depends on what you want to investigate. If you to make microscopic investigations (like I do) you should use real parameters (real grain distribution, shear modulus of quartz, poisson of quartz). In this case you can not validate your model, because calculation times are too high for macroscopic dimensions. For example you would need millions of particles to simulate a triaxial test. If you want to make macroscopic investigations you should use non-physical parameters (shifted grain distribution with higher particle radii, shear modulus of granular sand, poisson of granular sand). In this case you can validate your model, but parameters are different. Here you only need thousands of particles to simulate a triaxial test. -- You received this question notification because you are a member of yade-users, which 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
