Setting contacts for simulating bolted joints

I am running a random vibration study of an enclosure that consists of parts bolted together. I have removed the bolts to simplify the assembly and set a contact between the inside face of one bolt hole and the inside face of the other bolt hole. Running the simulation gives me errors as a result of the parts not being connected together properly.

I ran similar studies using this technique on cosmos 2008 without any trouble but now with 2009 I am getting error messages.

Is there an accepted method for simulation a bolted together assembly. What faces/edges should I select to get an accurate connection?
