MHD Field line tracing results

The zip files contain field line tracing results from a MHD simulation, which are used to create Figures 3 and 4 of a GRL paper, titled as "Investigation of Martian magnetic topology response to 2017 September ICME."该压缩文件包含磁流体动力学（Magnetohydrodynamics, MHD）模拟所得的磁力线追踪结果，用于制作题为"火星磁拓扑结构对2017年9月行星际日冕物质抛射（Interplanetary Coronal Mass Ejection, ICME）的响应研究"的《地球物理研究快报》（Geophysical Research Letters, GRL）论文的图3与图4。
