Inadequate restraints in an assembly with global bonded contact?

Hi,

I'm trying to run a stress simulation on an assembly I put together, but I get an error when I try to run it:

"The Iterative Solver stopped

Status code: 9 MATRIX_SINGULAR_OR_INDEFINITE

May not have adequate restraints.

No results saved."

For a basic analysis, I have set global bonded contact, fixed some faces on one end of the assembley, and am applying a load on the other end (see photo). I have all the components fully mated and defined, and all the contact surface between the parts register as an interference (coindidence). I'm not sure why it would not be restrained properly - maybe I don't understand how the global contact setting works.

If anyone has come across something similar or knows what the issue is here, I would greatly appreciate if you could please advise me in how to correct it.

thank you very much,

Eli
