摘要:

本文技术笔记描述了一种通用程序,用于从匹配的显式和对角隐式龙格-库塔方法对出发,构建数值求解微分方程的内部一致分裂方法。该程序将应用于合适的二阶配对,并考虑有或无质量守恒结束阶段的方法。对于这些分裂方法,研究了线性稳定性特性并展示了数值测试结果。

英文摘要:

In this technical note a general procedure is described to construct internally consistent splitting methods for the numerical solution of differential equations, starting from matching pairs of explicit and diagonally implicit Runge-Kutta methods. The procedure will be applied to suitable second-order pairs, and we will consider methods with or without a mass conserving finishing stage. For these splitting methods, the linear stability properties are studied and numerical test results are presented.
