(The simulation domain of the present method and FEM is both (0, 17.243a) × (−10a, 10a) × (0, 10a) along the x, y, and z directions. “Matrix calculation” stands for the CPU time consumed for the calculation of three matrices MA, MB, and MC; “call the matrices” represents the CPU time consumed by calling the matrices MA, MB, and MC.) (a) σvon along the x-axis (half-domain is plotted) and (b) CPU time consumption.
