PyTOUGHREACT is a Python package for automating reactive transport simulations including biodegradation reactions. It makes use of TOUGHREACT, TMVOC and TMVOCBIO executables for running the simulations. These executables are interfaced with python to automate the runs. It will be particularly useful for uncertainty quantifications, sensitivity analysis without the need to have a lot of files stored on your local computer. It builds on the PyTOUGH software which processes for the TOUGH2 executables.
PyTOUGHREACT is available on PyPI which is a repository of softwares built with the Python Programming Language. Before installing PyTOUGHREACT, it is required to have Python >=3.7 installed on your local computer. Python can be downloaded from the python.org website and installing it by following the instructions. Windows users should ensure that the path to the python is set in the environment variable to ensure availability everywhere.
Use the package manager pip to install PyTOUGHREACT.
pip install pytoughreactThe package can also be forked from this GitHub page and installation performed using
python setup.py install or py setup.py installBecause pytoughreact requires PyTOUGH, this library also needs to be installed. PyTOUGH can be installed by running the command below
pip install PyTOUGHimport os
