C. Guerin et al., A SHELL ELEMENT FOR COMPUTING 3D EDDY CURRENTS - APPLICATION TO TRANSFORMERS, IEEE transactions on magnetics, 31(3), 1995, pp. 1360-1363
A skin depth-independent shell element to model thin conducting sheets
is described in a finite element context. This element takes into acc
ount the field variation through depth due to skin effect. The finite
element formulation is first described, then boundary conditions at th
e edge of conducting shells and the possibility of describing non cond
ucting line gaps and holes are discussed. Finally, a computation of an
earthing transformer model with an aluminium shield modelled with she
ll elements is presented.
