OpenSIMPLY is an open source project for simulation modeling in Delphi, Lazarus, Free Pascal.
The project is free computer simulation software based on discrete event approach.
OpenSIMPLY is a scientific modeling software. It is much faster than popular software products, so you can obtain the simulation points also much faster.
OpenSIMPLY may be used as a traffic simulation software, network simulation software, as a software for science , for education and much more.
Simulation tool supports Windows and Linux, 32-bit and 64-bit platforms, a GUI and console application.
Write the model only once, simulate anywhere.
