QMcBeaver is an object-oriented program to perform Quantum Monte Carlo calculations on atoms and molecules. It is designed to be easy to modify, allowing new ideas to be quickly implemented.
TransimsGui and makeTransims allow users to automatically generate triptables, timetables and vehicle files, edit individual control files, create batch files for transims feedback processes, run exe-control file pairs and run batch files.
The Model Interaction Environment for Neuroscience provides tools for development, searching, editing, execution, and visualization of biophysical models, abstract mathematical models, and experimental protocols used in neuroscience research.
A 3D robots simulator written in python. Uses ODE physics and OpenGL/Inventor graphics. A differential wheels robot is provided. There is no user interface but the code is small and is intended to be easily extended for your simulations.
PyPhys is a set of physical quantity classes written in Python. The classes represent physical quantities (like length, pressure, energy, etc.) that can be assigned and extracted in many different units.
This application provides a web based visual browser for NetCDF files. The application provides a simple and friendly user interface for getting a quick overview of the data contained in the files.
PetriKit is a modular toolkit for Petri Net analysis. It allows the extraction of basic properties, extraction of invariants, and generation of reachability graph. Results can be formatted in plain text, HTML or XML files.

This project going to develop a thermodinamical server for chemical simulation, equip design, scientific module for other aplication or chemical education. Also the thermo server is developed to complete the project of chemical simulation Sim42.Spanish
Vision: To create a city simulation using a all volunteer organization that reaches across the entire world. The project will be created in a virtual workspace utilizing the communication devices that are attainable for a wide volunteer base.
This project aims to provide libraries in a few languages which allow for NORAD general perturbation element sets to be used in calculating the position and velocity of space objects.
The Automatic Model Optimization Reference Implementation, AMORI, is a framework that integrates the modelling and the optimization processes by providing a plug-in interface for both. A genetic algorithm and Markov simulations are currently implemented.
This project is A Mitochondrial OxydoReduction Simulation System. It consists of two linked projects: a program for displaying and analysing large biomolecular systems (Floral) and a multi-agent simulator for biomolecular oxydoreduction systems (AMORSS).
FreeBlockSim is a graphical block diagram editor/simulator for use with FreeSim++. FreeSim++ is a free to use C++ block library for dinamical systems simulation. Available soon on www.estudios-electricos.com
TAROT is a easy-to-use framework for Monte Carlo simulations in python. Calculations between different kinds of randomly distributed numbers are made as easy as basic arithmetics. Tarot provides an interactive graphical interface for interpretation.
edef - A small simulation framework for logic circuits, autoregressive processes, digital controller circuits and many more. Also there is a GUI application, that integrates a simple development environment and a circuit editor.
STOCHSIM is a stochastic simulator for biochemical reactions. The particles are represented as individual software objects which react according to probabilities derived from concentrations and rate constants. Simple spatial structures can be built.
Pysolar is a Python library for calculating the position of the sun relative to the earth as a function of latitude, longitude, and time. There is also code included for other problems related to the development of photovoltaic systems. Still in alpha.
This project simulates a multi-agent system (swarm) behavior both graphically and not. The purpose of this project is to research the properties suggested in "stability analysis of swarms" V.Gazi & K.M.Passino. Using the vpython library for 3D modeling
