Simscape Multibody Contact Forces Library keep passing through

Hello,

I'm using Simscape Multibody Contact Forces Library with imported bodies from CAO. But when I update some parameters like forces applied on bodies, or density of them, objects keep pass through each other by countering 3D sphere to plane block. Is it normal ? If yes, how to prevent it ?

Thank you in advance.

It may have to do with the spring-damping parameters simulating the contact forces; if the object are too heavy, the will "break through" the plane because basically the spring damping simplification is not enough strong to stop the object.

You can imagine it like having a heavy ball hitting a fragile plane - the reaction forces ar enot enough and it will break through.

Try increasing the parameters of the contact forces spring damping model.
