摘　　要：A fast, matrix-free implicit method based on the Lower-Upper Symmetric Gauss-Seidel （LU-SGS） method was developed to solve the three-dimensional incompressible Reynolds-averaged Navier-Stokes equations on multi-block structured grids. The method was applied to the simulations of a variety of flowfields around 3D complex underwater bodies with different appendages. The numerical procedure and results show that the method is efficient, reliable and robust for steady viscous flow simulations.A fast, matrix-free implicit method based on the Lower-Upper Symmetric Gauss-Seidel （LU-SGS） method was developed to solve the three-dimensional incompressible Reynolds-averaged Navier-Stokes equations on multi-block structured grids.
