# 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](./examples/LimitsToGrowth03.ipynb).
Documentation about the World models is in <https://abaucher.gitlabpages.inria.fr/pydynamo/> !
# Installation
- clone this repository and got to folder
- python -m pip install -r requirements.txt
- you can import pydynamo
# Note
_This is a beta version and all documentation and commands may not be complete or updated_
# Usage (see [BTmodel](./examples/BTmodel.ipynb) for example)
- Define the system equations in a function or file with pydynamo syntax
- Get a System object from this function or file
- Run, change parameters, re-run, plot
# 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.
