In this paper, a part of multigrid methods, namely Galerkin coarse grid approximation is discussed for the incompressible Navier-Stokes equations in general coordinates, for two-dimensional problems. Some possible prolongations and restrictions are given, with modifications for both Dirichlet boundary conditions and Neumann boundary conditions. An algorithm for computing the Galerkin coarse grid approximation is given.
