I would suggest in that case using clumps (rigid aggregates) of 2 or more spheres that would overlap in such a way that the overall share would more or less approximate what you need.
For the different particle size: have a look at TriaxialTest, it generates spheres at random of diameter .5 and 1.5 IIRC. Václav _______________________________________________ Yade-users mailing list [email protected] https://lists.berlios.de/mailman/listinfo/yade-users
