I'm doing a spinning simulation and halfway through the calculations I keep getting errors, I don't know what's going on, I need to troubleshoot, can anyone tell me how to do it.
That is not a scripting/customization-related question but more of a product/infrastructure one (like it could be that you are out of disk space etc.).
You should open an SR via the customer portal or post it on the forum (LS-DYNA) if you are a student.
