MAGIC产品介绍

美国Orbital ATK公司开发的MAGIC软件是一款电磁场时域有限差分粒子云网格模拟(FDTD-PIC)软件,主要用于仿真等离子体物理过程,包含空间电荷、电磁场和背景气体之间的相互作用。

MAGIC软件是一套基于FDTD-PIC算法的工具集。起初,软件用于为许多等离子体物理问题提供指导和过程演示,比如它被用于演示教课书上的物理现象和一些工程问题等。随着计算机科学的发展,软件也被发展成熟,功能也越来越强大。现在,成熟的MAGIC软件能够为电磁器件的设计和优化提供强力的仿真支持。而且,软件完善的同时,功能也更加丰富。早在1988年,MAGIC软件就被大学,企业和政府机构广泛应用。

MAGIC软件的工作原理简单来说就是:给定一个初始状态,仿真随时间变化的物理过程。软件通过求解完整的麦克斯韦方程组来获得电磁场分布;求解完整的洛仑兹力方程获得相对论粒子运动轨迹;求解连续性方程获得用于求解麦克斯韦方程组的电流和电荷密度。这套关于带电粒子与电磁场之间的自洽求解算法,一般称作EM-FDTD-PIC。

另外,MAGIC软件还提供一些其它功能强大的算法:处理复杂几何模型、材料属性、电磁波的入射和出射、粒子发射过程、背景气体的电离过程等。总之,软件能够应用于非常广泛的等离子体物理问题。

  • MAGIC软件包含两个核心建模软件:
  • 1) MAGIC2D ——二维半模型 (2D场和3D质点运动)
  • 2) MAGIC3D —— 全三维模型

MAGIC软件包含几大组成部分。Workbench是MAGIC2D 和 MAGIC3D 共用的输入文件脚本编辑器。Workbench同时集成了Build3D工具,它提供了一个丰富的三维几何开发环境。Sketchup几何插件,方便用户随心所欲的进行几何建模。Sketchup可以直接输出Workbench 和 Build3D 需要的几何模型。计算结果后处理使用REVIEW工具,一款通用图形处理器。
