I am trying to do a simulation on a barn door that is placed on a dump body. The door is supposed to hold an extra (350lbs) and hang off to the sides when it's fully open (See picture). When I run the study the door itself disappears in both stress and displacement study results. 

The way I setup the parts is I treated them as sheet metal. The hinges as solids and placed a pin connector inside it (stainless steel) and added edge welds between the hinge plates and the post (on the right), and between the hinge plates and the door (on the left).

The study seemed to run fine when I had bonded interaction between the parts. But I am trying to run the study with edge welds and it always results in the door disappearing.
