Implementation of the PeTS equation of state and corresponding Helmholtz energy functional¹ within the FeOs project. This project contains a Rust implementation as well as bindings to Python.

If you want to use feos-pets in Python, take a look at the feos-repository. feos contains multiple equation of state implementations in a single, easy-to-use Python package.

FeOs is a framework for equations of state and classical density function theory

You can learn more about the principles behind FeOs here.
