加速器磁体的有限元模拟

Finite-Element Simulation of an Accelerator Magnet: an Exercise

H. De Gersem, I. Kulchytska-Ruchka, S. Schöps

摘要:

本说明描述了加速器磁体有限元(FE)模拟的扩展练习。学生使用FEMM免费软件构建和模拟磁体模型。他们有机会练习有限元理论,包括麦克斯韦方程组,磁准静态公式,加权残差方法,选择适当的有限元形函数和代数方程组,从而通过填写表格进行指导。他们被邀请来实现一个简单的FE求解器的最关键的部分。最后,使用自己的软件再次模拟磁体,并开发一些问题专用的后处理例程。该练习教育加速器物理和电气工程专业的学生构建和模拟准确和可管理的FE模型,标准FE求解器背后的算法以及为自己的目的扩展FE求解器的一些想法。开展这项工作所需的所有文件均可免费查阅。

英文摘要:

This note describes an extended exercise on the finite-element (FE) simulation of an accelerator magnet. The students construct and simulate a magnet model using the FEMM freeware. They get the opportunity to exercise on the theory of FEs, including Maxwell equations, magnetoquasistatic formulation, weighted residual approach, choice of appropriate FE shape functions and algebraic system of equations, thereby guided by fill-in sheets. They are invited to implement the most crucial parts of a simple FE solver. Finally, the own software is used to simulate the magnet once more and to develop some problem-dedicated post-processing routines. The exercise educates students in accelerator physics and electrical engineering on the construction and simulation of accurate and manageable FE models, the algorithms behind a standard FE solver and some ideas to extend a FE solver for own purposes. All necessary files to carry out the exercise are freely available.
