Joint Constraint/Contact

Please login with a confirmed email address before reporting spam

Hi

I am using multi body dynamics in comsol 5.2a to model spring-mass systems. I've set up two rigid domains connected with springs. The first spring is connected to the "wall" and mass 1, and the second spring is connected to mass 1 and 2. When I give mass 2 an initial displacement, both masses accelerate. However, I want them to "hit" each other/account for contact. I tried to connect the masses with an prismatic joint with a spring, instead of a single spring. According to the Comsol user guide, it is possible define a joint constraint, but this causes an error.

Help would be extremely appreciated.

For some reason I was unable to attach the Comsol file to this message.
