Previously known as Extend, ExtendSIM is a brand of simulation software products from Imagine That. All four installation packages have the same core features required to run simulations of events or processes in different environments and involving groups or individual agents. The base product ExtendSIM CP has the necessary toolset for graphical construction of a continuous process simulation. It can create custom 2D animation for an Agent Based system or a Monte Carlo simulation. In addition, the package has more than a thousand functions for users to choose from while developing their simulations. Other full-featured products include the Operations Research (OR) toolkit, the Advanced Technology (AT) software, and the ExtenDSIM Suite for building a professional 3D environment for simulation models. Licenses offered are the stand-alone installations for individuals and the concurrent network license. Installations in Windows 7/XP/2000 needs a Pentium 4 chip or newer, at least 300 disk space, and recommended 1 GB RAM for an optimal performance.
