Stable Runge–Kutta–Nyström methods for dissipative stiff problems

Abstract: The definition of stability for Runge-Kutta-Nyström methods applied to stiff second-order in time problems has been recently revised, proving that it is necessary to add a new condition on the coefficients in order to guarantee the stability. In this paper, we study the case of second-order in time problems in the nonconservative case. For this, we construct an R-stable Runge-Kutta-Nyström method with two stages satisfying this condition of stability and we show numerically the advantages of this new method.Ke… Show more
