Hello everyone.

I am simulating heat transfer in electric power generator and I had to use anisotropic copper to define its winding. But I obtained very strange result of temperature distribution. There are few little areas where the temperature is very low (-150°C) and very high (480°C).

Also the convergence of thermal energy is quite normal but after 200 iterations it becomes to diverge. Does anyone know what could be cause of this issue??

Thanks for any suggestions.
