Simple steps to get started

1. Install basic libraries - pip install matplotlib cantera tensorflow
2. Install the SL-GPS library - pip install slgps
3. Test your installation by running any of the files in the tests folder
4. The trained neural network is stored as .h5 file which can be accessed and utilized to produced reduced mechanisms for any given composition, temperature and pressure.

SL-GPS

This repository contains the means to create a neural network architecture for dynamic chemistry reduction based on reduction results from Global Pathway Selection. The basic procedure is to first run adaptive GPS for 0D auto-ignition simulation so as to create a dataset. This dataset is later used for training the Artificial Neural Network (ANN). You can reach out to us at rmishra@tamu.edu (Rohit Mishra) or aaronnelson@tamu.edu (Aaron Nelson) for code issues, suggestions and/or pull requests. The step-by-step procedure to use this repository is as follows:

About

This code was developed entirely in Python 3. Dependent packages include Cantera 2, Tensorflow 2, pandas, sklearn, numpy, pickle, and networkx. Code for GPS has been copied from https://github.com/golsun/GPS and modified to work in Python 3.
