Solid contact problem
I'm trying to simulate a forklift laying down a series of bars on a support. I'm using version 5.0 beta and the chrono simulation to do so. After many many trials, the simulation keeps giving very strange behaviour : the bars are jumping randomly, with some contacts not respected.
Everything behaves as if the stiffness of the bars and supports would give near infinite forces in the contact zone, with no damping. Even an initial condition with no movement at all, gives bouncing solids...
What am I doing wrong ?

Dear user
First you can check the initial distance between the objects so that they are not overlapping.
If you still have problems you can send your case to dualsphysics@gmail.com
