This paper describes that the implicit temporal integration of MRA can be improved by the Schur complement with GMRES. The Schur complement retains the numerical accuracy at high CFL number, and GMRES reduces the calculation time. The target of this method is to reduce the calculation time in half, while achieving the numerical accuracy of the baseline solver even at high CFL number.
