The libcasm-xtal package is the CASM crystallography module. This includes:
- Data structures for representing lattices, crystal structures, and degrees of freedom (DoF).
- Methods for enumerating superlattices, making superstructures, finding primitive and reduced cells, and finding symmetry operations.
pip install libcasm-xtal
See the libcasm docs.
The libcasm-xtal 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.
