RESUMO

The possibility of accelerating the stationary numerical solution of viscid flow around aircraft by an explicit Godunov−Kolgan−Rodionov scheme through a local implicit smoother is considered. The smoother is introduced only in the hardest (from the viewpoint of explicit scheme stability) regions; e.g., in the deep of boundary layer where the spatial size of the grid cells is the smallest.
