Hello everyone,

I need to do simulation of roller on pipes. I'm aware that should be nonlinear study because roller slides on pipes, but I have to do it in static study. My question relates to marking on screen. Why there is some dislocation? I made contact - no penetration between roller and pipes, and only load is gravity.  Fixtures for roller are: no translation in X and Y axis, and no rotation in Z axis. I want to know dislocation and strees caused by weight of roller.

I would appreciate it, if someone could explain me how to solve this problem.

Greetings,

Janusz
