i am having trouble simulating a shaft collar on a shaft. It is a simple 1 piece shaft collar made for socket head cap screws. For the simulation, I split the collar into two halves and make a contact set (bonded) for the side that's meant to be once piece and use a bolted connector for the other side. I then set the component contact set between the collar and the shaft. All i want to see is the deformation of the screw pocket and I think this is a pretty easy simulation but its taking 45 min for the simulation to run. Any ideas? I want it to go by faster too because in the future I will need to test axial loading on the collar as well.
