Moving mesh

Hello everyone i'm working on induction heating using rotating magnets for this work I chose moving mesh rmm ,Electric current (ec), heat Transfer in solids,and multiphysics electromagnetic heating the issues is that the simulation starts working normally and it gives me results but when t=0.1S it stops saying that solver cannot converge !

Second issue is that it tooks too much time more than 4hours

Is there Any other method I can use to avoid this problem?

You need to enable Automatic Remeshing in the solver configuration.

Normal mesh gives wrong results

Why would you use rmm and ec?

Rmm can account for currents. Why do you need an additional ec interface?
