[motion] friction between objects

[tsjaikdus]

Is it possible to create some sort of friction of damping between plannar objects? The whole mechanism works fine except for one part that is pushed forward over a flat surface. The path of the part is not exactly defined, only begin and end point are known. Sometimes it moves close to what one would expect, but most of the time it bounces back and forth with every push (like it is moving on ice). I don't have much experience with motion, but linkages and all that work fine.

It is like a bulldozer pushing a rock. You know where the rock is and where it must go. But in NX Motion as soon as the bulldozer touches the rock, it jumps away. I've tried 3D contact, gravity and coulomb friction, but I don't know how it works and if it works at all. It seems to either do nothing or lock the mechanism completely. It also slows down the solver by a factor of 10 to 100, so it is not easy to try many setting.
