htpolynet 1.0.8

Automated MD System Builder for Amorphous Network Polymers

HTPolyNet

High-Throughput Polymer Network Atomistic Simulations

HTPolyNet is a Python utility for generating atomistic models of cross-linked polymer networks together with appropriate topology and parameter files required for molecular dynamics simulations using Gromacs. It is intended as a fully automated system builder requiring as inputs only the molecular structures of any monomer species, a description of the polymerization chemistry, and a handful of options describing desired system size and composition. HTPolyNet uses the Generalized Amber Force Field for atom-typing and parameter generation.

Installation

From PyPI:

pip install htpolynet

From source:

git clone [e-mail]:AbramsGroup/HTPolyNet.git
cd HTPolyNet
pip install -e .

Once installed, the user has access to the main htpolynet command.

The programs antechamber, parmchk2 and tleap from AmberTools must be in your path. These can be installed using the ambertools package from conda-forge or compiled from source.
