Shielding current analysis in High-Temperature Superconductor: Highly accurate evaluation of improper integrals for EFG

The modified element-free Galerkin (EFG) method has been proposed for calculating the shielding current density in a High-Temperature Superconductor (HTS). In the present study, the circle sub domain where each node is centered is installed in the analytic domain and the problem is discretized using sub domain instead of integration cells. Furthermore, highly accurate evaluation of improper integrals for EFG is propose.
