FFMD simulation with zero power and current (P = 0, I = 0) as the initial condition around the rapidly spinning black hole (a_* = 0.95). In this case, the initial electric field in the normal frame is zero (﹩{E}_{\tilde{\theta }}=0﹩). The dashed lines show quantities at t = 0. The dotted lines show the results at t = 50M. The solid lines show the results at t = 100 M. The horizontal dashed–dotted lines show the analytical values of the steady state, and the vertical dashed–dotted lines show the horizon of the spinning black hole. The values of P, I, and Ω_F at t = 100 M are almost the same as the corresponding values of the analytical steady-state solution.
