After assigning the impedance boundary on the structural elements of the transformer like frame, tank, etc.

For coils, have given both terminals and conductor details as well in copper material. But, resistance is not matching with the conductors provided, it is matching with the sheet terminal provided.

Is it required to give conductor dimensions to simulate stray loss?

How to calculate the Stray loss?

Hello, when you're working with impedance boundaries, it's important to note that they are used to simulate eddy effects without explicitly solving and meshing for the skin depth. This is particularly useful for calculating stray losses in conducting materials with very thin skin depth.
Regarding the resistance not matching with the conductors provided, it's possible that the issue lies in how the impedance boundary condition is applied or how the material properties are defined. It's recommended to use impedance boundary conditions when the skin depth is two orders of magnitude smaller than the conductor thickness

Hi Timos

Thank you for your response.

Can your provide me an model tutorial for computing stray loss of power transformer.
