Hello Dear I have 10 years of experience using COMSOL. I can debug your model. Also, can model it again from scratch. Let me know if you are interested. The file you shared shows too many errors; some are well-known, like unknown, just that the parameters are not defined. There is a convergence issue that is due to wrong boundary conditions or a rough mesh.

@maxscender

i can help you. The 200°C temperature jump suggests the mesh is likely not resolving the skin depth in the steel pins, leading to an overestimation of the volumetric loss density. I will check the boundary layer meshing and the non-linear relative permeability ($\mu_r$) of the steel, which often causes unrealistic heat spikes if not correctly defined. For the solver errors, I will audit the multiphysics coupling and the transition from the frequency-domain electromagnetic solver to the time-dependent thermal solver. The failure is often caused by inconsistent initial values or air-domain boundary conditions that prevent the convergence of the magnetic vector potential when steel is introduced.
