I was scanning the social net a few days ago, and came across this discussion in another community:
I am trying to create a dynamic simulation of a bouncing ball as part of my advanced CAD class. I am familiar with the mechanism tool (I am actually using Creo, but it is very similar to Pro/Engineer) however the only dynamic simulation I have ever analyzed was pendulum motion. With the bouncing ball I do not know how to set up a contact surface. If I model the rubber ball with a coefficient of restitution I assume it will bounce. So how would I set up this contact surface. All I need is a simple flat surface for the ball to bounce on.
If anyone could point me towards some tutorials or examples I would be very grateful.
Personally, I don't know how to do this (I haven't used Creo since it was Pro/ENGINEER - then again, I'm not at all in the PTC Creo business unit!) - but I *do* know that I work with some incredibly smart people. So, I connected with Moshe Baum on this. He replied:
A simple rigid ball can be illustrated easily (see corresponding files). The bounce can be controlled by the liftoff coefficient:
You can see a video of the simiulation Moshe did for me here:

Moshe was also gracious enough to send along a .zip file of the files used to create this. They are attached as well.
Thanks for your help, Moshe!
