Useful Open Source Tools

A number of people working in System Dynamics find R from the R project to be very useful. It is general purpose software for doing statistical analysis and graphing of data.

The SD-Tools Google Group is a place to discuss, debate, announce, coordinate, and improve tools related to the field of System Dynamics. Tools include methods to convert model formats (e.g, mdl, C, XMILE), generate documentation, create user interfaces and link to advanced analytic techniques, along with other projects.

Simulating System Dynamics Models in Python: This project is a simple library for running System Dynamics models in python, with the purpose of improving integration of Big Data and Machine Learning into the SD workflow. PySD translates Vensim or XMILE model files into python modules, and provides methods to modify, simulate, and observe those translated models.
