Abstract
AC losses in high-temperature superconductors are modelled as a highly non-linear diffusion process. Two empirical expressions for modelling effective resistivity of the conductor are used. Formulations in term s of both H and E are presented and it is argued, using dimensional an alysis, that working with E is numerically more efficient. Typical res ults calculated using a finite-difference scheme are shown.
