libcasm-configuration

The libcasm-configuration package is the CASM configuration comparison and enumeration module. This includes:

• Classes for representing supercells, configurations, clusters, and occupation events
• Methods for comparing and enumerating unique configurations, clusters, occupation events, and local environments
• Methods for generating orbits of symmetrically equivalent configurations, clusters, and occupation events
• Methods for copying configurations to make sub- or super-configurations
• Methods for generating symmetry groups, and constructing and applying symmetry representations
• Methods for performing irreducible space decompositions and finding symmetry adapted order parameters
• Methods for creating configurations with properties from mapped structures

Install

pip install libcasm-configuration

Dependencies

For symmetry group classification, we use the spglib package.

Usage

See the libcasm docs.

About CASM

The libcasm-configuration package is part of the CASM open source software package, which is designed to perform first-principles statistical mechanical studies of multi-component crystalline solids.

CASM is developed by the Van der Ven group, originally at the University of Michigan and currently at the University of California Santa Barbara.
