This method is based on a classical finite volume approach, but the values used to compute the fluxes at the cell interfaces near the solid boundary are determined so to satisfy
Two-grid discretizations have been widely applied to linear and non-linear elliptic boundary value problems: J. These methods have been extended to the steady Navier-Stokes
Theorem 4.1 (Unconditional stability of the scheme) Let us suppose that the discrete heat diffusion operator satisfies the monotonicity property (3.20), that the equation of
In this section, we build a pressure correction numerical scheme for the solution of compressible barotropic Navier-Stokes equations (1), based on the low order non-conforming

For Navier-Stokes equations, either compressible or incompressible, several types of methods provide an order two accuracy in space, global as well as local (near the interface):
