WebPhonopy has an interface to read and write FORCE_CONSTANTS or force_constants.hdf5. To read and write these files are controlled by force constants tags and FC_FORMAT, READFC_FORMAT, WRITEFC_FORMAT. VASP users can use VASP DFPT interface to create FORCE_CONSTANTS from vasprun.xml.

WebJul 26, 2024 · The primitive cell is passed to phonopy, which constructs super cell systems with small atomic displacements. A LAMMPS calculation is performed on the displaced systems to evaluate the atomic forces on each atom without relaxing. The measured atomic forces are then passed back to phonopy, which computes force constants for the system.
