Ok im doing some work for a company that produces industial hinges for heat exchangers, so the caps can be removed saftely. This things are about 2.5 feet tall. Now i ran a simulation and i got about 1/16 deflection and they measured it in the field and they got 5/16 deflection. Now ran this as a assembly. Im not allowed to include any pictures of these. The bolts are 10 mills smaller then the holes they are in. I modeled the bolts just into the flange as cylinders extrusions. The hinge and the flange are the correct size and material. Would using virtual bolts or refining the hell out of the mesh make a big difference? Were trying to figure what the issue is, so we can correct them in future jobs
