Easy Java Simulations Modeling and Authoring Tool

written by Francisco Esquembre
content provider: Wolfgang Christian

Easy Java Simulations (EJS) is a Java program that enables both programmers and novices to quickly and easily prototype, test, and distribute packages of Java simulations.

Version 4.1 adds grouping and affine transformations to 2D drawing Elements.

Version 4.2 adds new ODE solvers and zero crossing events.

Version 4.3 adds Java 3D support. If Java 3D is not installed on a client computer, the 3D object is rendered using simple 3D. Java 3D is installed with Mac Snow Leopard. Windows and Unix users can download Java 3D from the developer site.

Version 4.3.1 adds translation facilities.

Version 4.3.2 adds model elements.

Version 4.3.3 adds add support for delay differential equations.

Version 4.3.4 introduces new model elements for parallel programming.

Version 4.3.5 adds video support using the Xuggle open-source video library. The easiest way to install Xuggle is to install the OSP Tracker video modeling program from this site.

Please note that this resource requires at least version 1.5 of Java (JRE).

EJS and the Modeling Cycle

Author: Wolfgang

The advantage of EJS for physics teaching is that it forces students to separate the model into logical parts and to separate the model from the view. Students learn the logic of computer modeling using loops and control structures and study algorithms used in professional practice when building models.
