| Research Abstract |
Since evaluation of the shielding current density is indispensable to engineering applications of high-temperature superconductors (HTSs), various numerical methods have been so far developed for analyzing the shielding current density. However, all of the methods have been plagued by the following two fatal difficulties : (1) slow speed due to implicit schemes and (2) disability to treat HTS samples containing cracks or holes. In the present study, two novel numerical techniques, i. e. constitutive-relation-modification method and virtual-voltage method, are proposed for resolving the above two difficulties.
