Abstract
Parallelized element-free Galerkin (EFG) method using OpenMP is evaluated and the evaluation of AC loss of axisymmetric high-Tc superconductors (HTSs) by using EFG is presented. Formulation of the electromagnetic behavior of shielding current density in an HTS gives a system of time-dependent integro-differential equations. After discretizing the weak form of the problem based on EFG, the axisymmetric simulation code for analyzing the time evolution of the shielding current density on HTS is developed.In the present study, the simulation code for analyzing the time evolution of the shielding current density in HTS by using EFG is developed. Results of the computation shows that the CPU time of parallelized EFG in the case of 4PU is 3.8 times faster than that of 1PU. Furthermore, the AC loss is calculated numerically by use of the values of the shielding current density.
