摘要

本文综述了公认的分析和域离散化方法（有限差分法FDM、有限元法FEM）在磁流体动力学（MHD）现象建模中的一些应用，用于聚变相关研究和纳米器件中使用的量子结构。因此，对于某些简单的激发形式，已经实现了等离子体平衡的Grad-Shafranov方程（GSE），并给出了矩形等离子体的结果。此外，分别用FDM和FEM对稳态薛定谔方程进行了解析求解和数值求解。

A note on the use of analytical and domain discretisation methods for the analysis of some phenomena in engineering physics

The paper reviews some applications of the well-established analytical and domain discretisation methods (finite difference method-FDM, finite element method-FEM) in the modelling of the magnetohydrodynamics (MHD) phenomena for the fusion-related research and quantum structures for use in nanodevices. Hence, Grad-Shafranov Equation (GSE) for the plasma equilibrium has been implemented for certain simple excitation forms, and the results obtained for the rectangular plasma have been presented. Furthermore, the stationary Schrodinger equation is solved analytically and numerically via FDM and FEM, respectively.
