Runge-Kutta-Nystrom Method with FSAL Property

3 Runge-Kutta-Nystrom Method with FSAL Property. - We give the following definition. [Pg.174]

Definition 2. A Runge-Kutta-Nystrbm method is said to have the FSAL [Pg.174]

For the Runge-Kutta-Nystrom method described by equations (13)-(17), Aguiar, Simos and Tocino have produced the corresponding method that has the FSAL property. This method is given by  [Pg.175]

For w 0, the above method is equivalent to the classical symlpectic second algebraic order Runge-Kutta-Nystrom method mentioned in the paper of Calvo and Sanz-Serna.  [Pg.175]


In 52 the author develops a symplectic exponentially fitted modified Runge-Kutta-Nystrom method. The method of development was based on the development of symplectic exponentially fitted modified Runge-Kutta-Ny-strom method by Simos and Vigo-Aguiar. The new method is a two-stage second-order method with FSAL-property (first step as last). [Pg.208]
