内容記述 | Efforts are made to reduce computing time of the pointwise relaxation implicit Discontinuous Galerkin method for reaching convergence by utilizing p- multigrid scheme and also by solving a block diagonalized matrix instead of a fully loaded dense matrix to advance a time step. It is shown that computing time to obtain a converged solution for a typical test problem becomes 1/2 of the computing time of the original pointwise implicit relaxation method. | |||||
