Pydynamo
Pydynamo is a module to define, run and analyse system dynamics.
It was originally created to run the World3 model [2], written in DYNAMO language [1]. Included in the module are functions to convert DYNAMO code to pydynamo syntax. All scenarios of Limits to Growth, updated with 2003 version, are shown in LimitsToGrowth03.
Documentation about the World models is in https://abaucher.gitlabpages.inria.fr/pydynamo/ !

Author
Achille BAUCHER for my internship at the LIG-lab. I used some functions from pyworld3 [3], and nice explanations by it's author Charles Vanwynsberghe.
