hello i have this shaft supported in 3 points with only gravity applied to it.

the shaft misteriously wont stay on its supports, anyone can figure out why?

i have global connector to bonded, then the contact between each support to the shaft is no penetration and node to surface.  fixed contacts are the ones under the 3 supports

i wanted to run simulation study to see how stresss, displacement and reaction forces would change if i moved the center support,s height starting being at same height as the 2 others then 1, 2, 3mm...  until it doenst touch anymore

thanks
