Application of Parallel Computation in Numerical Simulation of Laser Propulsion
As for the problem of numerical simulation of laser propulsion of three dimensions and multi-sub domains, the domain decomposition strategy based on message passing mechanism is applied in this paper to realize parallelization. The cell-centered finite volume scheme is performed to solve Euler equation. A fivestep Runge-Kutta scheme of explicit integral model is used for time advancement. The spatial discretization of inviscid fluid is estimated by high-order Godunovtype scheme. We test some different examples on a cluster system and the results show the smallest number of speedup is more than 5.19 when the degree of parallelism is 8. In a word, parallel computation is an inevitable choice to achieve the aim of accelerating the study of the mechanism of laser propulsion.
