WebJun 14, 2024 · Dear all, I run a simulation at 10K with a 5x5x5 supercell of bcc Si (250 atoms). I then calculate the 2nd and 3rd order force constants (IFC2, IFC3). I use the IFC2 with phonopy to calculate the phonon dispersion and this latter overlaps with the one obtained with phonopy and finite displacements. However, the IFC3 are all exactly null. WebThe phonopy reader for second-order force constants fails. Steps to reproduce from hiphive.io.phonopy import read_phonopy_fc2 fcs = read_phonopy_fc2('FORCE_CONSTANTS_2ND', format='text') The FORCE_CONSTANTS_2ND file can be downloaded here . This is a "full" force constants file, see #271. What is the …
