Abstract

The AC loss calculation is crucial for the thermal analysis of the High Temperature Superconducting (HTS) magnet. Generally, the critical state model is used to calculate the AC loss value of the HTS conductor with Finite Element Method (FEM). The mesh of the model have a large impact both on the convergence and the accuracy in calculation processes. In this paper, we investigate the effect of different meshes on the AC loss calculation of HTS conductors using a second generation tape model. Both triangular and quadrangle element with fix number of elements and predefined distribution type meshes have been used. The results illustrates that quadrangle with geometric sequence is the best choice when calculating the AC loss in HTS tape.
