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.
Are you sure you need solve _contact_bodies_problem_ (elastic or plastic)?
Or you need kinematics problem solve?
"Finite bodies modeling" help you. But it it can be solved in external soft, like "Code Aster" or other...
Ty Yef Alex,
I'm sure code_aster and finite element analysis would somehow do the trick. But it sounds a bit heavy solution to my just for fun project.
If looked my animation You see what I need. I was hoping I can somehow make a group of spheres and say: "bounce a little when You contact do not go through each other"
I think this would be a very good application for the Discrete Element Method.
This looks like a very similar problem to this one:
You can use the SimScale in your browser and for free if you are a student.
Thank You Richard,
yes it looks. My idea was make simulation pure Inventor base run but SimScale looks interesting. I must take a good look at it some rainy day.
