Hello,
I am currently working on an electromagnetic simulation using a transient magnetic analysis with thermal coupling. I am trying to obtain simulation results for a total simulated time of 60–300 seconds, using a time step of 0.001 s and a write interval of 1000 time steps.
The simulation runs successfully for shorter simulation times (for example, 0.05 s) and with smaller write intervals. However, when I increase the total simulated time to 60 s or more, an unknown error occurs and the simulation terminates unexpectedly. Interestingly, the simulation consistently stops at approximately 4 seconds of simulated time.
I would greatly appreciate your assistance in identifying the cause of this issue and finding a suitable solution. In particular, I would like to understand whether the problem could be related to the time-stepping settings, write interval, memory requirements, solver settings, or the thermal-electromagnetic coupling.
If required, I can provide the simulation setup, solver configuration, error message/log file, or relevant screenshots for further investigation.
Thank you in advance for your support.
Best regards,
Aziz
