-PyBox has been built in the [Anaconda Python 3.6 environment](https://www.anaconda.com/download/#macos). [Assimulo](http://www.jmodelica.org/assimulo) is *currently* the numerical core of PyBox. The Assimulo Ordinary Differential Equation (ODE) solver package allows us to use solvers designed for stiff systems. [UManSysProp](http://umansysprop.seaes.manchester.ac.uk) is used to automate predictions of pure component and mixture properties to allow gas-to-particle partitioning simulations. Before methods of installation are described, below is a list of both 3rd party and Python native modules required. You can click on each to visit the project website with further details, including useful information on installation pertinent to the section on using an [alternative](#Alternative) installation procedure to either Docker or Conda.
