Hi all,
I have a simulation assembly, where I have several parts pushing a tubes (with an separating contact, with a 0,15 of friction coeficient). The tubes are fixed, and the other moves sliding throw 2 guides and for some reason, this part cross the fixed part.
In this assembly, I have 12 equal parts doing the same, but the problem occurs only in 2 of them.
Bellow you cas see in orange, the sliding parts, that moves throw its guides in the direction that are shown by the rows:

We have a contact botween the pushers and the tubes:

But when we start the simulation, 2 of the 12 pushers cross the tube, as you see bellow:

Do you kwow where is the problem?
