I had a problem with the contacts, I've made two nonlinear studies. both are same, the only difference between them is the contact to join the parts of the assembly.

In one of them I used the rigid connection and it doesn't check the bolts (first image).

In the second one I used the bonded contact an it works, all the bolts and its forces resulting are listed (second image).

So, I can't differentiate why it happens in this way, can you help me? I need the forces resulting in the study of the first image.
