The paper represents an efficient multigrid algorithm without the problem-dependent components for solving the Navier–Stokes equations in primitive variables formulation on structured grids. The algorithm consists of Vanka smoother, pressure decomposition and robust multigrid technique. Detailed description of the proposed approach and results of numerical experiment are given.
