I am trying to set up a simulation of a bouncing ball for my students, yet my ball keeps passing through my floor how do I prevent this? I have attached my model

thanks in advanced

I am dealing with a simular problem. How did you solved it?

I'm assuming you have already put a sphere-to-plane block in your system. If you haven't then you must define a contact force between the plane and the sphere.Then double click on the Sphere to Plane Force block , set the contact stiffness parameter(under contact tab) to relatively high value(i.e.1e10N/m would be enough i guess).

Were you able to fix this? i used contact forces library but yet it passes through each other. I dont know what i did wrong. can anyone give me any tips for using contact forces library correctly. i followed the shere on table(plane) example?

i figured it out. the issue was not in the stiffness or damping. it was in the coordinate frame of planar surface. it was horizontal and the contacts were supposed to be vertical.

Thank you for your time.
