Finite-Element Modeling of Thin Conductors in Frequency Domain

This article describes a technique that allows representing thin wires in finite-element models very efficiently and accurately by idealized line elements. The approach exploits the analytical solution of the problem of the wire taken in isolation to correct the finite-element solution of the problem of the idealized wire with a vanishing radius. The method is validated in the 2-D magnetodynamics frequency-domain case for systems of parallel wires.
