Hello, I'm attempting to analyze an assembly of two electromagnetic multi-turn coils each with an iron core. I followed the instructions in the video "COMSOL webinar - modeling coils and electric devices" https://www.youtube.com/watch?v=n7xhNFzWQ1U, specifically the helmoltz coil construction. However, the computation time was taking over a half hour to compute so I'm wondering what I did wrong. Any assistance would be appreciated, I attached my mph file for inspection. Thank you, Michelle
