I am modeling a hinge in ANSYS and have not been able to get it to run without crashing. So far, I've been modeling the relationship between the two sides of the hinge and the hinge pin using just contact connections, but when I did a modal analysis, I found that the contact connections were not being obeyed between the hinge pin and the two sides of the hinge. Only after switching to a joint connection would the simulation run without crashing. Can someone tell me what would cause ANSYS to ignore a contact connection? I'm relatively new to using ANSYS (though I've used other FEA systems before), so if there is a default that I need to change to account for things like slop in the hinge, or some such thing, I would not be aware of it.
