      We will present a method for obtaining high-order, non-oscillatory results for staggered mesh (velocities at cell boundaries), internal energy-based hydrodynamics codes using a simple modification of the well known Artificial Viscosity technique. This method is derived by particular approximate Riemann solvers.
      The resulting method will be shown to deliver results comparable to such cell-centered, total energy-based method as Flux Corrected Transport (FCT) and high-order Godunov schemes.
