pyMOR is a library for model order reduction (MOR) in Python, implementing generic algorithms for MOR based on abstract vectors and operators. This allows integrating pyMOR with external PDE solvers or other numerical simulation tools. Furthermore, pyMOR includes various methods for model-based MOR of parametric partial differential equations and control systems, as well as data-driven methods. This tutorial will give an introduction to the design of pyMOR and demonstrate a range of available methods.
