WebWork flow of phonopy is shown schematically. There are two ways to calculate, (1) atomic forces from finite displacements and (2) given force constants. You can choose one of them. Forces on atoms or force constants are calculated by your favorite calculator (shown by the octagons in the work flow). 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 ...
