Random or regular packing are first created for a large volume and then it is cut according to the predicate (so the same as deleting the intersecting particles). If you want dense packing composed of both clumps and spheres, it is a bit different question.. One option would be to create loose packing of defined properties and then compress it (e.g. using PeriIsoCompressor or TriaxialTest). cheers Jan [1] https://yade-dem.org/wiki/Howtoask -- 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 : [email protected] Unsubscribe : https://launchpad.net/~yade-users More help : https://help.launchpad.net/ListHelp
