In the third part of his Introduction to Dynamic Simulation on CATIA 3DEXPERIENCE tutorial series, Maxime Chagnot talks about groups of contact between several parts. He uses the scenario of 4 balls falling into a funnel to show the concept of group contacts. You’ll learn how to create contacts between the balls and the funnel, as well as between each ball, and add friction and restitution coefficients. You’ll create a dynamic scenario in Mechanical Systems Experience, try different diameter sizes of the funnel hole, and study the behavior of the falling balls.
