Transient study - Convergence issues

Please login with a confirmed email address before reporting spam

Dear all,

I am experiencing an issue with the model attached to this request. My goal is to analyze the behavior and response of a superconducting tape under the action of an external field generated by appropriately applying currents in the system’s exciter.

When I modeled the superconducting region by approximating it as a line, I did not encounter any problems. However, now that I am treating it as a rectangular domain (also because I plan to include additional non-superconducting layers in the future), the model shows convergence issues.

I am fairly confident that the formulation is correct as implemented, since I have verified it against several references in the literature, and it is consistent with those sources.

Could you please help me resolve the issue related to Study 2 – Transient? I have tried setting the stationary Study 1 as the initial condition and tested various solvers, but without any positive results.

Thank you very much for your support.
