Fusion simulation issue

[Anonymous]

we have not been able to perform a simulation on our models since the latest update.

It is slow and the tool movement is not fluid and has locked the program at times.

CAM Simulation? I too find it not very fluid, but I think I narrowed it down to IPS (In Process Stock) still being calculated. What happens if you turn IPS off, or wait until it's done calculating before simulating?

For the red line at the bottom, that indicates that your computer is calculating the simulation stock. Regarding the looping, right click in the canvas and make sure this isn't checked:
