Efficient Nordsieck second derivative general linear methods: construction and implementation
- 48 Downloads
In this paper, by considering the order conditions for second derivative general linear methods of order p and stage order \(q=p-1\), we investigate construction and implementation of these methods in the Nordsieck form with \(r=s+1=p\), where s and r are the number of internal and external stages of the method, respectively. Constructed methods are A- and L-stable which possess Runge–Kutta stability property. Some numerical experiments are provided in a variable stepsize environment to validate the efficiency of the constructed methods and reliability of the proposed error estimates.
