(Video - Flash - Java - html - Software ) Simulation is a software tool designed to create computer simulations. It is a media for making, doing, creating and best of all and can be used as a modeling tool. The construction, simulation, visualization, and analytical description of the physics model are connected during the construction process. That is, most of the programming work is done by generating an automatic code based on the existing text instructions, the mathematical formula about the form and selecting the menu / mouse from the designer to create the GUI for the simulation. The Java source code is generated automatically and converted to class files. In addition, a Jar file and HTML pages are created associated with users to view the simulation with the browser.
