NodePy: A package for the analysis of numerical ODE solvers

Installation

NodePy requires Python 3.5 or later. To install with pip, do:

pip install nodepy

This will automatically fetch dependencies also. It will not fetch optional dependencies, which include networkx, cvxpy and scipy (that are used only in a few specialized routines and/or examples). The optional dependencies can be installed with pip.

Overview

NodePy (Numerical ODEs in Python) is a Python package for designing, analyzing, and testing numerical methods for initial value ODEs. Its development was motivated by my own research in time integration methods for PDEs. I found that I was frequently repeating tasks that could be automated and integrated. Initially I developed a collection of MATLAB scripts, but this became unwieldy due to the large number of files that were necessary and the more limited capability for code reuse.

NodePy represents an object-oriented approach, in which the basic object is a numerical ODE solver. The idea is to design a laboratory for such methods in the same sense that MATLAB is a laboratory for matrices.

Documentation can be found online at

To get started, you can also have a look at the examples folder, beginning with an introduction as Jupyter notebook.

The development version can be obtained from
