不可压缩流和迭代求解器软件包（IFISS）包含可以与MATLAB或Octave一起运行的软件，用于创建一个计算实验室，用于不可压缩流问题的交互式数值研究。它包括混合有限元方法和后验误差估计的计算解决方案，连同国家的最先进的预处理迭代求解器所产生的离散线性方程组的离散化算法。在本文中，我们给的味道代码的主要功能，并说明其适用性，使用几个案例研究。我们的目标是表明IFISS可以是一个有价值的工具，在教学和研究。
The Incompressible Flow & Iterative Solver Software (IFISS) package contains software which can be run with MATLAB or Octave to create a computational laboratory for the interactive numerical study of incompressible flow problems. It includes algorithms for discretization by mixed finite element methods and a posteriori error estimation of the computed solutions, together with state-of-the-art preconditioned iterative solvers for the resulting discrete linear equation systems. In this paper we give a flavor of the code's main features and illustrate its applicability using several case studies. We aim to show that IFISS can be a valuable tool in both teaching and research.
