Symmetry doesnt work correctly

Hello,

 

i have an assembly that you can see at the picture attached to this thread. The problem is, that the rods are connected with a symmetry constraint. The global contact is "bonded" and the result looks very strange. After changing to "no penetration" the result looks more realistic. The rods are connected to the plate with a "bonded" contact.

 

I have tried serveral things but nothing works. After reducing the plate thickness in several steps, the simulation with bonded contact works. I dont understand the problem. In the picture you can see the same simulation with a difference of 1mm in thickness. In "no penetration" simulation it works always.

 

Please excuse the bad english. Its not my native language.
