Comparison of Numerical Methods for Modelling of Superconductors

Different FEM formulations have been developed in order to model the electromagnetic behaviour of type II super-conductors. The paper presents a comparison between simulations with A-V formulation models implemented in two FEM software packages (FLUX2D and FLUX3D) and a numerical method based on analytical model for superconductors in applied magnetic field. These models can be used for superconductors with complex geometry and power-law current-voltage characteristics. Simulated is a 37-filamentary tape with applied transport current in self-field and AC magnetic field parallel to the wide side of the tape. A good agreement is found between the AC loss and current distributions obtained with the different models.
