A locally implicit method for solving the Euler equations is described. The method uses finite volume spatial discretization, locally inplicit time integration, and Jameson-type artificial dissipation terms. The convergence rate is significantly enhanced with a multi-grid iteration and an extrapolation in time. The method is demonstrated with transonic and supersonic flows over an NACA 0012 airfoil.
