EagleClaw

Easy Access Graphical Laboratory for Exploring Conservation Laws

Introduction

Please read this page and then click on the link to a list of on-line examples at the bottom of this page.

EagleClaw is based on the Clawpack Version 5.0 software, primarily designed for solving hyperbolic systems of conservation laws.

EagleClaw provides a web-page interface to Clawpack with the following goals:

To allow those studying hyperbolic problems to experiment with several examples without the need to download and install code or read a user's manual.
To allow potential users of Clawpack to try it out before downloading and installing.
To provide a simplifed interface that may be useful also for those modifying and running Clawpack on their own computer. A web server is easy to start in Python on your local machine to serve your own EagleClaw pages (see claw/README).
To facilitate on-line documentation of the Clawpack software using a new approach to Literate Programming. html pages are generated from Fortran and Python programs using claw/doc/clawcode2html.py, a version of mathcode2html designed for use with Clawpack. See the Riemann solver for acoustics for an example.

Browser issues

These web pages were designed using Firefox and they work reliably with Firefox on Linux, Windows, and Mac OS X.

They don't seem to work always with Safari or Internet Explorer, for reasons not yet understood.

jsMath issues

Some of these web pages use jsMath to display mathematics typeset in latex. If this equation:

\[ \frac{\partial}{\partial t} q(x,t) + \frac{\partial}{\partial x} f(q(x,t)) = 0 \]

looks like latex instead of being typeset, you probably need to install some fonts, which is easy to do.

Click on the jsMath icon in the lower corner for some other useful things.
