Abstract介绍如何在并行自适应工具包PARAMESH的基础上实现磁流体并行自适应计算,并在工具包的基础上实现了中心迎风差分的CT格式、相应的插值算法和误差控制等功能模块;特别是为了保持磁流体计算所要求的磁场散度为零的限制,实现了八波方法。最后给出的三个磁流体算例表明,其计算能自动地捕捉磁流体模型的奇性变化,并可保持散度为零。该工作将为国内基于磁流体的空间天气建模研究和应用打下良好的基础。
Other AbstractThis paper introduced how to use AMR package-PARAMESH to implement MHD parallel AMR computation. Implemented center-constrained transport scheme,corresponding interpolation method,and error estimation controller to accomplish AMR computation. In order to keep⊿·B=0,implemened eight-waves method in PARAMESH. Three tests show that AMR can capture the character of MHD model and keep divergence constraint. Our work will contribute to the research and application of space weather MHD modeling in China.
