Runge

With the help of Runge you can use an interactive solver for systems with common differential equations by entering the necessary parameters to immediately get the solutions. It can be handled by math students and teachers alike.

After a brief and uneventful setup procedure, you are welcomed by a clean and intuitive interface, where you can begin a project by selecting the type of system, along with the dimension and independent variable.

In the following steps, you can specify parameters when it comes to the start and end t, H, Hmin, Hmax, Eps and P, as well as create as many macros as you want. Afterward, you can ask Runge to start solving the current system using the current values. It shows solutions on the bottom part of the screen and lets you save the project to file to resume it later.

As far as program customization is concerned, you can configure font settings and switch to another UI language. The software application also includes a 2D drawer for plots, in accordance with the current equation. The graph can be printed or exported to file with the BMP, ICO, JPEG, JPG, PBM, PGM, PNG, PPM, TIF, TIFF, WBMP or XPM format.

There were no kind of issues in our tests, thanks to the fact that the application didn't freeze, crash or prompt error messages. It left a small footprint on system resources usage, running on low CPU and RAM. Runge comes packed with handy options to help you solve differential equations.
