已编制完成三维非线性流体力学与激光传播耦合并行模拟程序,用以研究高强度激光在稀疏等离子体中的自聚焦和成丝不稳定性形成机制.介绍该三维并行程序中所使用的数值方法和并行算法.
A parallel code, with fully three-dimensional nonlinear hydrodynamics coupled with light wave propagation, is implemented to study mechanism of laser beam self-focusing and filamentation instability as high intensity laser propagates in a large size underdense plasma. Numerical method and parallel algorithms are introduced.
