The simulation was not failing until the update. After the update, the simulation fails without any severe errors in the log file. I have renamed all the thermal zones based on space names as per the other similar post here to prevent non-alphanumeric characters causing an issue, but still no luck. Only thing that seemed to have helped is system RESTART. Is there any other solution to this? The files are hosted here if you would need it: https://ufile.io/o0ya1. Also, I used this file as a seed model in PAT, I'm not sure if that had anything to do with these issues. I'm lost trying to figure out the issue for the past two days. Please let me know if you need further information to help.
