摘要

本文介绍了一种新的等离子体表面相互作用模拟程序——日冕-航天器相互作用(SCSI)。该计划的主要重点是在其实现中保持模块化和通用性。为此，SCSI采用面向对象的方法进行编程，该方法由一组按类组织的数值方法和一个主文件组成，该主文件将这些方法连接起来，以便运行模拟。该程序还包含一个嵌入式网格系统。这些网格几乎独立运行，允许用户在域的不同区域执行不同的数值方法。该程序通过模拟卫星与太阳风在距离太阳表面8.5 R处的相互作用来进行测试。结果显示SCSI和以前的代码之间有很好的一致性，并证明了该程序能够捕获等离子体表面系统中存在的主要物理现象。

Development of Object-oriented PIC Code for Simulation of Plasma Flow Around a Satellite in Solar Corona

This paper introduces a new plasma-surface interaction simulation program called Solar Corona – Spacecraft Interaction (SCSI). The program's main focus is to keep modularity and generality in its implementation. For this purpose, SCSI was programmed with an object-oriented approach, composed of a set of numerical methods organised in classes and a main file that connects them in order for the simulation to run. The program also contains a system of embedded meshes. These meshes run almost independently and allow the user to execute different numerical methods in different regions of the domain. The program is tested by simulating the interaction of a satellite with the solar wind at a distance of 8.5 R from the surface of the Sun. Results exhibited good agreement between SCSI and previous codes and demonstrated the capability of the program to capture the main physical phenomena present in plasma-surface systems.
