摘要

摘要: 将计算机辅助设计技术用于粒子模拟建模,能极大地提高粒子模拟方法的实用性。在对复杂真空电子学微波源、毫米波源和太赫兹源的建模需求分析基础上,采用面向对象和模块化设计方法,实现了三维粒子模拟CAD建模系统。该系统可以对各类复杂器件进行可视化建模,并生成提供给核心计算程序使用的器件参量描述文件。使用该系统分别在圆柱坐标系和直角坐标系下建模,模拟了磁绝缘线振荡器和扩展互作用振荡器。结果表明,三维粒子模拟CAD建模系统具有很好的实用性。

Abstract: Expanding application of computer-aided design (CAD) technique to the particle-in-cell (PIC) simulation will greatly make a large space towards the practicability of PIC method. Using object-oriented and modularized design methods, a three-dimensional CAD system for PIC simulation is realized based on the analysis of the requirement of modeling complex vacuum electronic microwave sources, millimeter-wave sources, and terahertz sources. The CAD system can visually model various complex devices and generate the parameter description file for the kernel calculation. Using this system, a magnetically insulated transmission line oscillator (MILO) and an extended interaction oscillator (EIO) are modeled and simulated in cylindrical and Cartesian coordinates respectively. The results show the practicability of the three-dimensional CAD system for PIC simulation.
