WebNov 24, 2024 · Reads sets of forces from a Phonopy FORCE_SETS file. Returns: A list of (disps, force_set) tuples. disps are lists of one or more (atom_index, disp) tuples listing the atomic displacements in the configuration. force_set is a list of vectors listing the forces on the atoms. """ force_sets = [] with open (file_path, 'r') as input_reader: WebThis option requieres phonopy to be correctly installed and FORCE_SETS file has to be calculated first. The result is a set of phonon mode projections (one for each phonon) which are either displayed in the screen in different windows or stored in a file (one column for each phonon) sorted from lower to higher frequency.
WebSetting up a phonopy calculation is similar to settings up a relaxation (or any other workflow supported by FHI-vibes ). To ensure that our physical settings don't change, we will copy the relaxation.in obtained in the previous part of the tutorial to the new working directory and rename it to phonopy.in. WebJul 26, 2024 · The measured atomic forces are then passed back to phonopy, which computes force constants for the system. Plots are then created for the band structure, …
