On the Efficient Implementation of Implicit Runge-Kutta Methods
WitrynaThe focus is especially on implicit Runge–Kutta schemes of Gauss, Radau IA, Radau IIA, Lobatto IIIA, Lobatto IIIB and Lobatto IIIC collocation type up to order six. Furthermore, we also use a SDIRK (singly diagonally implicit Runge–Kutta) method to demonstrate, that for general implicit Runge–Kutta methods the additional order … WitrynaSeveral classes of implicit Runge-Kutta methods are shown to be BS-stable and BSI-stable: Gauss, Radau IA and Radau IIA schemes. (iii) In [9] (this issue, pp. 515-534) the property of BS-stability is used as a tool ... Radau IA and Radau IIA methods are B-stable for problems with a positive one-sided Lipschitz constant. 2.
