A SEAMM plug-in for building periodic boxes of fluid using Packmol
Project description
SEAMM Packmol Plug-in
A SEAMM plug-in for building periodic boxes of fluid using Packmol
This plug-in takes the molecule in the current system and creates a periodic box containing many copies of the molecule in order to simulate a fluid.
Free software: BSD license
Documentation: https://molssi-seamm.github.io/packmol_step/index.html
Features
Multiple ways to specify final cell:
Size of the cubic cell and density or number of molecules or number of atoms.
Volume and density or number of molecules or number of atoms.
density and size of the cubic cell or volume or number of molecules or of atoms.

History
- 2024.3.19 – Updated installer for new scheme
packmol-step-installer now uses the new scheme, which supports both Conda and Docker installation.
Added seamm-packmol Docker image
- 2024.1.16 – Adding support for containers
Added the ability to work in Docker containers.
- 2023.9.6 – Using fractional coordinates for periodic systems.
By convention, SEAMM is using fractional coordinates for periodic systems. The PACKMOL step was creating periodic structures with Cartesian coordinates, which can be a bit confusing, though it did not affect any reauls. This change fixes the issue.
2023.2.15 – Restructured documentation and moved to new theme.
- 2022.5.31 – Substantial enhancements
Added ability to solvate molecules and increased the options to include
spherical regions
cubic and rectangular regions
cubic and rectangular unit cells for periodic systems
input molecules from any combination of system/configurations and SMILES
reworked GUI to be more intuitive.
2021.11.27 – Fixed bug with atom types.
2021.10.25 – Bugfix for problems with ideal gas approach.
- 2021.8.29 – Multiple different molecules available via SMILES
This release adds
the ability to directly generate multiple different molecules from SMILES, giving the stoichiometry for packing into the fluid box.
specifying the desired cell with the temperature and pressure, along with one of the volume, length of the box side, number of molecules or number of atoms. This uses the ideal gas law, so will only be reasonable at higher temperatures and lower densities.
Additionally, internally the release adds integration tests to check whether the module works properly in the SEAMM environment.
2021.6.3 – internal change for improvements in parsing the commandline
2021.5.25 – Added installer for Packmol executable.
2021.2.11 (11 February 2021)
Updated the README file to give a better description.
Updated the short description in setup.py to work with the new installer.
Added keywords for better searchability.
2021.2.4 (4 February 2021)
Updated for compatibility with the new system classes in MolSystem 2021.2.2 release.
2020.12.5 (5 December 2020)
Internal: switching CI from TravisCI to GitHub Actions, and in the process moving documentation from ReadTheDocs to GitHub Pages where it is consolidated with the main SEAMM documentation.
2020.11.2 (2 November 2020)
Updated to be compatible with the new command-line argument handling.
2020.10.7 (7 October 2020)
Added citations to be printed and stored.
2020.9.29 (29 September 2020)
Updated to be compatible with the new system classes in MolSystem.
2020.8.1 (1 August 2020)
Fixed bugs in the edit dialog.
0.9 (15 April 2020)
General bug fixing and code cleanup.
Part of release of all modules.
0.7.0 (17 December 2019)
General clean-up of code and output.
Part of release of all modules.
v0.3.0 (27 August 2019)
First running version with reasonable output.
0.2.0 (13 August 2019)
First release on PyPI.
