How to add 3D contact joint between 39 lotto balls/spheres
My model is lotto machine with 39 balls/spheres. I have succesfully made Inventor Dynamic simulation with 12 balls. But number of joints increase dramatically if I want to make DS with 39 balls.
PROBLEM: How to make 3D contact joint between 39 spheres?
See my simulation Lotto machine + simulation
I have done this simulation very hard way. 3D contact between all balls and machine rails and machine sphere and hook sure.
Ball 1, contact between 2,3,4,5,6,7,8,9,10,11,12
Ball 2, contact between 3,4,5,6,7,8,9,10,11,12
Ball 3, contact between 4,5,6,7,8,9,10,11,12
Ball 11, contact between 12
I don't want to do manually these contacts with 39 balls. It will give me 38+37+36...+1 contacts (aritmetic serie) = 741 3D contact joints. HUH!
Any idea and I would be grateful

PS. If You want to try DS Yourself, You can download my model assembly .rar (machine, balls, all parts included) from forum.
I think this would be a very good application for the Discrete Element Method.
This looks like a very similar problem to this one:
