Hello everyone, I am trying to simulate a magnetoelectric device (with sandwich structure of magnetostricitive and piezoelectric materials) under the AC magnetic field. For that, I have made a Helmholtz coil which is driven by external electrical circuit of AC voltage. But the problem is that after simulation an error massage like "NaN or Inf found when solving linear system using SOR". The simulation absolutely fine with stationary domain. But I could not identified what is going wrong with frequency domain. I have attached the simulation file.
Can anyone help me in this regard? It will be a great help for me.
Looking forward for your kind reply. Thanking you Sincerely Sujoy
