How to make solid parts solid?

In a real assembly, parts stop moving when they bump into each other. In a default SolidWorks motion study or Cosmos analysis, they don't: forces push unconstrained parts through other parts, and Cosmos results show deflected parts pushing through other parts instead of constrained by them. How can I make parts act "solid"?

In the motion manager you need to create a contact constraint and pick all the bodies that you want to be included for collision analysis in your model. If you drop a ball from a height to a surface it will pass through unless both parts are included in the contact constraint.

The icon is located on the motion study tab between the spring and gravity icons and looks like a cam and a follower. Select all the parts you want contact to be detected for.
