Modeling high-temperature superconductors containing an array of holes

We have recently implemented a finite-element model for the penetration of the magnetic flux inside a bulk superconductor containing an array of holes (thin-wall superconductor), with the help of the open-source code GetDp. In this talk, I introduce the A-phi formulation used, with edge elements and spanning tree gauges. I explain how a time-iterative method allows one to make calculations with fewer time steps, and compare the obtained results with those derived by the Brandt method.
