Getting started with ELI

Downloading an AppImage

Each model has an associated AppImage, which is a single file that contains Linux executable and supplementary files.

Click on a link below to download an ELI AppImage.

Note: An ELI AppImage is a graphical application for modern GTK-based Linux desktops, e.g., Ubuntu or Fedora.

  • If you wish to run ELI under Microsoft Windows, consider running Ubuntu under WSL2 and running the AppImage within that environment. (However, this approach has not be thoroughly tested.)

  • If you wish to run ELI under Linux without GTK, please submit a request for building an AppImage that includes GTK libraries.

Installation

  • Installation is easy: save the AppImage to your Desktop folder and change its permissions to executable.

Running ELI

  • Double click on an AppImage icon to open ELI. Click on Quit to close ELI.

  • The working directory is ELI.home in your home directory. Supplementary files, such as documentation, input files for demonstration and testing, and auxiliary client-server scripts, are placed here.

  • As a first example, run quad -i in/quad/demo/tour. Then click on the Read button, which is located on the left panel. ELI reads the tour input file and executes the commands it finds. Execution is paused at each Pause command; to continue past a pause, click on Read.

Other models

ELI has general algorithms for constructing wave curves and bifurcation loci for any 2-component system of conservation laws. All that is required is an implementation, in some computer programming language, of the formulae for the flux and accumulation functions along with their first and second derivatives.

If you have a 2-component system of conservation laws that you wish to explore, it might be possible to establish a scientific collaboration that includes implementing this model in ELI. Initiate a discussion.
