An interactive book about the Riemann problem for hyperbolic PDEs, using Jupyter notebooks. Work in progress.
This repository contains source files for a book that illustrates Riemann solutions and approximate Riemann solvers in Jupyter notebooks. The print version of the book is available from SIAM, and also as an ebook. You can view a pdf version of the contents, preface, and index.
Riemann Problems and Jupyter Solutions Theory and Approximate Solvers for Hyperbolic PDEs by David I. Ketcheson, Randall J. LeVeque, and Mauricio J. del Razo SIAM, 2020. ISBN: 978-1-611976-20-5 ebook: DOI 10.1137/1.9781611976212
See https://bookstore.siam.org/fa16/bonus for additional information and links to the html rendered notebooks. These are static views (no execution or interactive widgets), but some notebooks include animations that will play.
The recommended way to fully experience the book is by running the Jupyter notebooks:
Start from the table of contents given in the notebook Index.ipynb, which is also shown below. The notebook Index2.ipynb lists some notebooks that are not in the SIAM book, some of which are still under development. Additional notebooks may appear in the future.
The FA16 branch of this repository corresponds to notebooks as converted into the SIAM book. The master branch may be updated in the future.
To install the dependencies, first install a Fortran compiler. Then do the following in a terminal:
pip install clawpack git clone https://github.com/clawpack/riemann_book cd riemann_book pip install -r requirements.txt jupyter nbextension enable --py widgetsnbextension pip install jupyter_contrib_nbextensions jupyter contrib nbextension install --user jupyter nbextension enable equation-numbering/main
You can test your installation by running
A table of contents and suggested order for reading the notebooks is given in Index.ipynb.
If you want to compile the PDF locally, you must also install the package bookbook.
Rather than installing all the dependencies, if you have Docker installed you can use
$ docker pull clawpack/rbook
to obtain a docker image that has all the notebooks and dependencies installed. This was built using the Dockerfile in this repository, which could be modified to build a new image also containing other material, if desired. See Docker.md for further instructions.
Rather than installing anything on your own computer, you can run the
notebooks on the cloud using the free

This may take a few minutes to start up a notebook server on a Jupyterhub. Then navigate to
Index.ipynbto get started.
