Description
In this contribution, we present a fast and accurate finite element approach for modelling the electric and magnetic behavior of periodic composite superconducting conductors. It uses two coupled two-dimensional models and accounts for the conductor periodicity via circuit equations. This allows to capture three-dimensional effects while leading to a significant reduction in computational time compared to conventional three-dimensional models. The method is directly applicable to multifilamentary Nb-Ti, Nb$_3$Sn, MgB$_2$, and Bi-2212 wires, and can be extended to other periodic HTS conductor geometries.
