I downloaded Solidthinking yesterday and have been trying to optimize a simple part with a plate where force is applied to, a fixed rod, and a given designspace. It seems to get stuck around 50% (one time at 58% and a few times at 52%). After running for around 3 hours I deleted one and retried it. After a while it gave the error 157. I am not sure what I am doing wrong. I am running it on a HP Zbook studio G3. I attached a reference image below of the set-up. I hope someone will be able to help me further.
