This package was created with Cookiecutter and the molssi-seamm/cookiecutter-seamm-plugin project template.
Developed by the Molecular Sciences Software Institute (MolSSI), which receives funding from the National Science Foundation under award OAC-1547580 and CHE-2136142.
History
- 2024.3.17 – Updated the installer
Updated the installer to use the new version of the SEAMM installer.
Finalizes installing either with Conda or Docker
- 2024.3.4 – Allowing short names for method and DFT functionals
Added short names for the methods (Hamiltonians) and DFT functionals.
Catch errors in Psi4 calculating properties for e.g. CISD(T) method
- 2024.2.29 – Completed support for containers
Fixed issues with running amd64 containers on arm64 systems.
- 2024.1.11 – Changes to allow running in containers.
Moved to the new executor and ensured it still runs directly.
Fixed bugs in printing the summary output.
- 2023.8.23 – Fix for installation of Psi4
Psi4 is now available on CondaForge, so install from there if requested.
Psi4 crashes if asked to optimize and atom, so change to doing a single point energy is optimization is requested for and atom.
- 2023.8.22 – Enhancement of orbital plots
Added structure to the orbital plots
Fixed a bug if the default number of cores was not ‘available’
- 2023.6.4 – Enhancements
Added thermochemistry substep to compute the vibrational and other corrections for thermochemistry.
Added ability to create .cube files for plotting the density and orbitals.
- 2023.2.21 – Added control over SCF convergence
Able to set convergence criteria.
Options for damping. level shifting and second-order SCF
Set default for number of steps for optimization to 6*nAtoms to make it more explicit.
- 2023.2.17 – Checking more thoroughly for errors in Psi4
Check and throw errors for various issues when running Psi4, including whenever it does not complete successfully according to the output.
- 2023.2.16.1 – OptKing will not die!!!
Yet another part needed to be removed.
- 2023.2.16 – Thoroughly removing calls to OptKing
OptKing is causing compatibility issues, and is not currently being used in the Python, so am temporarily removing it.
2023.1.23 (23 January 2023)
Corrected bugs, including if no dispersion term requested
Added preliminary version of accelerated optimization using MOPAC for Hessians, etc. May not fully work at the moment.
Updated documentation theme and structure to match new style.
2022.11.18 – Added total charge and multiplicity to Psi4 input
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.
2020.9.28 (28 September 2020)
Improved handling of results
Selection depends on both calculation and method.
Arrays can be stored in variables (but not tables!).
Multipoles gathered as arrays rather than a large number of scalars.
2020.8.1 (1 August 2020)
Fixed minor bugs.
2020.7.3 (24 July 2020)
Added control options for number of threads and amount of memory to use.
2020.7.2 (23 July 2020)
First pass at specifying number of threads and amount of memory.
2020.7.1 (23 July 2020)
Added substep for optimization.
2020.7.0 (21 July 2020)
First release on PyPI of initial working version.
