ByteFF2

This repository contains the model used for the paper Bridging Quantum Mechanics to Organic Liquid Properties via a Universal Force Field。

ByteFF-Pol is a polarizable force field parameterized by a graph neural network (GNN), trained on high-level quantum mechanics (QM) data, thus eliminating the need for experimental calibration. ByteFF-Pol achieves exceptional accuracy in predicting the thermodynamic and transport properties of small-molecule liquids and electrolytes, outperforming SOTA traditional and ML force fields

Trained Models

The trained_models folder contains the trained model for ByteFF-Pol and its corresponding configuration (.yaml) file.

How to use

Code and examples are available in the byteff2 repository.
