Summary:
Acceleration technique for analyzing the shielding current density in a high-temperature superconductor with multiple cracks has been proposed. In this technique, it is necessary to solve the simultaneous linear equations obtained from the discretization of the finite element method and the Backward Euler method. By applying the linear equations to the GMRES(k) method with {H}-matrix method, the results of computations show that the CPU time of the GMRES(k) with {H}-matrix method is much faster than that of the ツtextit{LU} decomposition.
