MAGIC產品介紹

美國Orbital ATK公司開發的MAGIC軟件是一款電磁場時域有限差分粒子雲網格模擬(FDTD-PIC)軟件,主要用於仿真等離子體物理過程,包含空間電荷、電磁場和背景氣體之間的相互作用。

MAGIC軟件是一套基於FDTD-PIC算法的工具集。起初,軟件用於為許多等離子體物理問題提供指導和過程演示,比如它被用於演示教課書上的物理現象和一些工程問題等。隨著計算機科學的發展,軟件也被發展成熟,功能也越來越強大。現在,成熟的MAGIC軟件能夠為電磁器件的設計和優化提供強力的仿真支持。而且,軟件完善的同時,功能也更加豐富。早在1988年,MAGIC軟件就被大學,企業和政府機構廣泛應用。

MAGIC軟件的工作原理簡單來說就是:給定一個初始狀態,仿真隨時間變化的物理過程。軟件通過求解完整的麥克斯韋方程組來獲得電磁場分布;求解完整的洛侖茲力方程獲得相對論粒子運動軌跡;求解連續性方程獲得用於求解麥克斯韋方程組的電流和電荷密度。這套關於帶電粒子與電磁場之間的自洽求解算法,一般稱作EM-FDTD-PIC。

另外,MAGIC軟件還提供一些其它功能強大的算法:處理複雜幾何模型、材料屬性、電磁波的入射和出射、粒子發射過程、背景氣體的電離過程等。總之,軟件能夠應用於非常廣泛的等離子體物理問題。

  • MAGIC軟件包含兩個核心建模軟件:
  • 1) MAGIC2D ——二維半模型 (2D場和3D質點運動)
  • 2) MAGIC3D —— 全三維模型

MAGIC軟件包含幾大組成部分。Workbench是MAGIC2D 和 MAGIC3D 共用的輸入文件腳本編輯器。Workbench同時集成了Build3D工具,它提供了一個豐富的三維幾何開發環境。Sketchup幾何插件,方便用戶隨心所欲的進行幾何建模。Sketchup可以直接輸出Workbench 和 Build3D 需要的幾何模型。計算結果後處理使用REVIEW工具,一款通用圖形處理器。
