by better I mean: there is no error "Exceeded 1000 tries to insert ...". I prefer to set radius and radius deviation at a fixed value, so that I have control on the sieve curve. In fact I want a sample of target size, eg. 10x10x10cm (after the initial compaction phase) and with a given sieve curve. To achieve that I am fixing the sieve cure by controlling radius, and I am trying different xyz and different number of particles, until I get what I wanted. Can this be done in some better way? -- Janek Kozicki http://janek.kozicki.pl/ | _______________________________________________ Mailing list: https://launchpad.net/~yade-users Post to : [email protected] Unsubscribe : https://launchpad.net/~yade-users More help : https://help.launchpad.net/ListHelp
