WebShengBTE is a software package for solving the Boltzmann Transport Equation for phonons. Its main purpose is to compute the lattice contribution to the thermal conductivity of bulk crystalline solids, but nanowires can also be treated under a hypothesis of diffusive boundary conditions. In addition to the thermal conductivity itself, ShengBTE ... WebIn phonopy, the crystal symmetry is automatically analyzed from the input unit cell structure file that doesn’t contain the symmetry information. WebYou don't need to convert the force constants from phonopy to .extxyz. In this example the force constants are produced using phonopy and then rotational sum rules are applied to those via hiphive. There is also some information on reading force constants here.
