README.md

Computational Hyperbolic PDE

These codes are based on Clawpack and the book

R. J. LeVeque, Finite volume methods for hyperbolic problems, CUP.

Most of the codes have been taken from various Clawpack repositories and modified slightly in some cases.

To install Clawpack, see the instructions here

https://cpraveen.github.io/comp/clawpack.html

Directory book contains original codes used for the book; they will not work with latest clawpack, you need to use v4.3 but I do not recommend this. Many of the codes have been converted here

https://github.com/clawpack/apps/tree/master/fvmbook

Examples from book on "Riemann Problems and Jupyter Solutions"

Read it here

https://www.clawpack.org/riemann_book/html/Index.html

or read the code on github

https://github.com/clawpack/riemann_book

More examples

  1. Shallow water
    1. Tsunami from ocean onto shelf and beach
    2. Sloshing liquid in a bowl

Visualization

After generating the solution files, e.g., for classic solver using

make .output

The solution files should now be in _output directory. Start ipython and run the following commands

import clawpack.visclaw.Iplotclaw as Iplotclaw
ip = Iplotclaw()
ip.plotloop()

Press enter to get the first plot and for later frames.
