[Yade-users] [Question #191084]: clumps - particle size distribution
New question #191084 on Yade: https://answers.launchpad.net/yade/+question/191084 Hi guys, do you think is possible to follow a specific particle size distribution while using clumps? Does anybody have experience with that and maybe can suggest a simple method how to do it?

I have experience how this can be done with PFC. The procedure is as follows: 1. Generate your packing with spheres. 2. Create templates of your clumps. 3. Replace spheres with clump templates (clumps should have same real volume as your spheres). for example I send you the fish-code of my model: ;make a template of a clump with 2 overlapping spheres: clump template make dyad 2 radii 0.5 0.5 pos (0.25, 0.5, 0.25) (-0.25, -0.25, -0.25) ;replace 5 percent of the spheres by clumps with my template called dyad: clump replace 1 dyad 0.05 Regards, Christian -- 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

Question #191084 on Yade changed: https://answers.launchpad.net/yade/+question/191084 Christian Jakob posted a new comment: Of course! In the case of two overlapping spheres you have to replace ( ) with ( () ), so you have calculate the volume of a sphere cap and subtract this from the sum of the volumes of this two overlapping spheres. formula see here: http://en.wikipedia.org/wiki/Spherical_cap In PFC it is done automatically with this replace command, very comfortable... Please let us know, when you are successfull. -- 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
