| Abstract: | In this paper,a class of real time parallel combined methods(RTPCM)for the numerical simulation of a partitioned stiffly large system is presented.By means of combining the parallelism across the system with the parallelism across the method,stiff and nonstiff subsystems are solved in parallel on parallel computer with a parallel Rosenbrock method and a parallel RK method respectively.Their construction,convergence and numerical stability are discussed,and the numerical simulation experiments are conducted. |
