  abstract	= {This paper concerns energy stability on curvilinear grids
		  and its impact on steady state calulations. We have done
		  computations for the Euler equations using both high order
		  summation-by-parts block and diagonal norm schemes. The
		  calculations indicate the significance of energy stability
		  in order to obtain convergence to steady state.
		  Furthermore, the difference operators are improved such
		  that faster convergence to steady state are obtained. The
		  numerical experiments also reveal the importance of high
		  quality grids when high order finite difference methods are
		  used. }
