论文摘要
Ifiss是一个已建立的MATLAB有限元软件包，用于研究解决部分微分方程（PDE）的策略。 IFISS3D是一个新的附加工具箱，可将椭圆PDE的IFISS功能从两个空间维度扩展到三个空间。开源MATLAB框架提供了一个计算实验室，用于实验和探索有限元近似和误差估计以及迭代求解器。该软件包旨在作为想要了解最先进的有限元方法的讲师和学生的教学工具。对于研究人员来说，这也将是有用的，它是任意较大维度的可再现测试矩阵的来源。
IFISS is an established MATLAB finite element software package for studying strategies for solving partial differential equations (PDEs). IFISS3D is a new add-on toolbox that extends IFISS capabilities for elliptic PDEs from two to three space dimensions. The open-source MATLAB framework provides a computational laboratory for experimentation and exploration of finite element approximation and error estimation, as well as iterative solvers. The package is designed to be useful as a teaching tool for instructors and students who want to learn about state-of-the-art finite element methodology. It will also be useful for researchers as a source of reproducible test matrices of arbitrarily large dimension.
