Robert Caulk posted a new comment: >if I wanna make the strength have a deviation like1±21%, then by changing the sphere radius distributed in 1±10% or to change the alpha to(0.79,1.21), will I get the same distribution range for the strength regardless of the distribution types? Nope, you'll need to do some analytical statistics to get the exact form of the PDF. In the default case, strength is proportional to the square of the minimum interacting radius. In the case where you try to impose some uniform factor, alpha, you are multiplying a uniform distribution by a squared uniform distribution which still depends on the minimum radius. Hence why I said: "But it will not be exactly uniform, since you are factoring a uniform distribution of particle sizes squared (and especially not uniform since you are taking the minimum of interacting bonds)" IF you want an exact uniform distribution of strength, you follow this part of what I said: "If you prefer to follow your own instincts and override everything to control the strengths as you like, you can do that on your own with a simple for-loop in python which iterates on the physics of each interaction:" -- 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 : [email protected] Unsubscribe : https://launchpad.net/~yade-users More help : https://help.launchpad.net/ListHelp
