Webphonopy--symmetry • Phonopycan analyze the symmetry of the atom geometry, detect the primitive (output as PPOSCAR) and give the Bravaislattice (BPOSCAR). • Useful for … WebDec 2, 2024 · Phonopy can give you the eigenvectors of the modes. In conjunction with the 'q' shifts (displacements for the supercells, generated by phonopy), this can tell you the nature of the mode. For example, if the eigenvector points in the same direction as the 'q' shift, it is a longitudinal mode.
