"Model may not have adequate fixtures."

I'm attempting to run FEA on two hinges with a specific weight on them, and I'm having trouble getting the fixtures/connections correct.


The basic setup is two hinges mounted to a door.  I have the geometry and density of the door set so I have the weight correct for an odd shaped door we have designed.  I'd like to set the wall side of the hinges (or the bolt holes) as fixed, and have the gravity.


I've tried several types of connections between all of the parts. I ended up taking the hinge pins out, and added pins under connectors in it's place.  I have pins set to all connecting bolt holes between the hinges and door to keep alignment.  Then I have tried both "no penatration" and "bonded" contact between the hinges and the door (seperately).  I have also done the same between the two sides of hinges (also did this when the hinge pins were unsupressed).


I have attached two pics to show this.


Please let me know if anyone has any ideas of what should be added/changed.
