pyscal2 2.10.21

Python library written in C++ for calculation of local atomic structural environment

pyscal - python Structural Environment Calculator

[!TIP] Check out pyscal3, a completely new pyscal which is faster and can handle a large number of atoms, with a much more user-friendly interface.

Complete documentation with examples available here.

pyscal is a python module for the calculation of local atomic structural environments including Steinhardt's bond orientational order parameters during post-processing of atomistic simulation data. The core functionality of pyscal is written in C++ with python wrappers using pybind11 which allows for fast calculations with possibilities for easy expansion in python.

Steinhardt's order parameters are widely used for identification of crystal structures. They are also used to identify if an atom is solid or liquid.

Installation

pyscal can be installed directly using conda by the following statement-

    conda install -c conda-forge pyscal

From repository

pyscal can be built from the repository by-

    git clone https://github.com/pyscal/pyscal.git
    cd pyscal
    python setup.py install --user
