FeliX (Functional Enviro-economic Linkages Integrated neXus) is a system dynamics model of global social, economic, and environmental Earth systems. More information can be found at:

This repository contains two previous versions of the FeliX model used in various publications, as well as the current version under development. The model is developed on the modelling software Vensim (www.vensim.org), therefore the users should have Vensim installed to be able to display and simulate the model. While the previous versions can be displayed and simulated by the free version of Vensim (Vensim PLE), the current version requires features that are available only in the licensed version, which is Vensim DSS. The users who have no access to Vensim DSS can still display the model by using the Vensim Model Reader.

A full documentation of the model can be seen in Felix3_ModelReport.pdf.
