Abstract | 本文针对一类分解的刚性大系统提出一类并行组合方法。该方法将系统分割与方法分割的并行化方法相结合,采用显式线性多步方法求解非刚性子系统,采用隐式线性多步方法求解刚性子系统。文中讨论了方法的相容阶,收敛性和数值稳定性。数值试验结果表明该方法对于分解的刚性大系统的求解是可行的。 |
Other Abstract | Through combination of the parallelism across the system with the parallelism across the method,Parallel Compound Methods are constructed for the numerical solution of a class of partitioned stiff systems.Nonstiff equations are integrated by a explicit linear multistep method while a imlicit linear multistep is used for the stiff part of the system. Their order condition,convergence and stability are discussed.The numerical test are conducted on a parallel computing system and the results demonstrate the method is viable to this class of partitioned stiff system. |
