For information on building a model, assigning attributes to regions within the model and meshing the model, see 2D Static Magnetic Analysis of this manual and the Modeling and Meshing Guide.

Electromagnetic field penetration in conducting bodies is a function of frequency, permeability, and conductivity. Calculating the field and Joule heating losses accurately requires that the finite element mesh be fine enough at the surface of the conductor to capture the surface phenomena. In general, you should model one or two elements at a minimum through the skin depth. You can estimate the skin depth from the following equation:
In the equation above, Δ is the skin depth (in meters), f is the frequency (in Hertz), μ is the absolute permeability (in Henries/meters), and σ is conductivity (in Siemens/meter).
