| Abstract: | In this paper, a class of real time combined RK Rosenbrock (RTCRKR) methods are presented for numerical simulation of a partitioned stiff dynamic system. Stiff and nonstiff subsystems are solved by a Rosenbrock method and an explicit RK method, respectively. Their construction, convergence and numerical stability are discussed. The numerical simulation experiments show that the class algorithm is efficient. |
