✦ Synopsis

The numerical code for simulating the time evolution of the shielding current density in the high-temperature superconductor has been developed on the basis of the element-free Galerkin method. The magnetic flux density generated by the shielding current density is calculated by use of the code and its spectral analysis is performed. The results of computations show that an increase in the amplitude of the applied ac magnetic field will cause the appearance of the third harmonics of the magnetic flux density. Furthermore, it is found that the rapid growth of the third harmonics arises not from the B-dependence of the critical current density but from that of the flow resistivity.
