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. Webphonopy.in Obviously the most important section in the phonopy.in input file is [phonopy] which containts information about how the supercells with displacements should be set up to compute the force constants from the finite-differences method. An explanation for the full list of keywords is found in the documentation.
