Matscipy is a generic materials science toolbox built around the Atomic Simulation Environment (ASE). It provides useful routines for:
- Plasticity and dislocations
- Fracture mechanics
- Electro-chemistry
- Tribology
- Elastic properties
In addition to domain-specific routines, it also implements a set of general-purpose, low-level utilities:
- Efficient neighbour lists
- Atomic strain
- Ring analysis
- Correlation functions
- Second order potential derivatives
Matscipy can be installed on Windows, Linux and x86 macos with:
python3 -m pip install matscipy
To get the latest version directly (requires a working compiler):
python3 -m pip install git+https://github.com/libAtoms/matscipy.git
Compiled up-to-date wheels for Windows, Linux and x86 macos can be found here.
Sphinx-generated documentation for the project can be found here. Since Matscipy is built on top of ASE's Atoms and Calculator objects, ASE's documentation is a good complement to Matscipy's.
Issues can be used to ask questions about Matscipy.
Contributions, in the form of bug reports, improvement suggestions, documentation or pull requests, are welcome.
To run the tests locally, from Matscipy's root directory:
python3 -m pip install .[test] # installs matscipy + test dependencies cd tests/ python3 -m pytest .
When developing matscipy, it can be useful to have an editable install of the source directory. This means that changes to the source code are directly reflected in the matscipy install. We are using Meson and meson-python as a build system, and there are some restriction to editable installs.
The editable install only works with the --no-build-isolation option:
python3 -m pip install --no-build-isolation --editable .[test]
If you get the message:
ERROR: Tried to form an absolute path to a dir in the source tree.
then you are most likely try to install into a Python virtual environment that is located inside your source directory. This is not possible; your virtual environment needs to be located outside of the source directory.
The package requires:
- numpy - http://www.numpy.org/
- scipy - http://www.scipy.org/
- ASE - https://wiki.fysik.dtu.dk/ase/
Optional packages:
- quippy - http://www.github.com/libAtoms/QUIP
- atomistica - https://www.github.com/Atomistica/atomistica
- chemview - https://github.com/gabrielelanaro/chemview
