Solver is not respecting SF constraint
Hello,
My problem is quite simple, I'm running a topology optimization on my design space with forces and displacement constraints. I'm using a Minimize Mass objective with a SF of 2.2, a minimum thickness of 0.0065m, Speed/Accuracy is 'faster'. I have ten load cases at the moment and the higher force load cases are consistently not met. After a result has been solved I'll use the analysis tool and find that multiple areas have a sf of 0.1. I've tried solving using only one of the failing cases instead of all ten but I'm met with the same failure. I think I'm missing something fundamental and I would appreciate the help.
Side note: These sims are taking ~28 hours, I haven't been able to speed it up even with the following PC. CPU: Intel(R) Xeon(R) Gold 5118 CPU @ 2.30GHz 2.29 GHz (2 processors), 128GB Ram, 2x NVIDIA TITAN V graphics cards.
I'll focus on the braking load as it's the simplest:
