The paper handles the problem of accuracy loss for high-order numerical CFD schemes on non-point-to-point structured grids. The proposed method employs a novel direct flux optimization approach on non-mathched boundaries. The method allows to preserve the flux conservativity, ensures high accuracy and essentially facilitates Navier-Stokes computations for complex aircraft configurations.
