Magnetic circuit in my simulation and magnetic losses

Dear PLECs Team,

I hope you are doing well. I am currently facing difficulties with the magnetic circuit in my simulation. I initially simulated using an ideal transformer, and everything was working perfectly. However, after inserting a magnetic model of the three-winding, three-leg transformer, I started receiving some unexpected results. I have attached the simulation file for your reference. Could you kindly review it and let me know where I might be making a mistake?

Additionally, I would like to calculate the losses in the core and winding of the transformer. I have come across the concept of magnetic resistance, but I am unsure how to calculate its value. I would greatly appreciate your guidance on this process.

Thank you for your time and assistance.

Regards,
Aaqib Sheikh
