Hello,
I am using Ansys to model some simple plates, and I keep getting a DOF error. I know what it typically means, but for some reason it is connected to my contact area. Let me explain. I have 2 circular plates with holes in the middle. They are stacked one on top of the other. The bottom plate has a much larger inner radius. I am simply applying a pressure to the inner diameter of the top plate. In real life these plates are bolted together along the outside diameter, but in ansys I thought I would just create a contact area between the plates where they contact. I used 'bonded-always' contact. I just want to simulate these plates being stuck together and then see how they react. Is there a trick to this or is contact wizard even the right tool?
When I run the solution int eh ansys cmd window, it says "***NOTE*** No contact area was detected for this contact pair." I dont know why.... but something causes my solution to cause a DOF error.
Sorry for the long post. Suggestions? thanks
