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). WebThe phonopy-gruneisen script requires three phonon calculations at corresponding three volume points. One is for eigenvectors at the equilibrium volume ( V) and the remaining two are for Δ D ( q) with slightly larger and smaller volumes than V.

WebJul 26, 2024 · The primitive cell is passed to phonopy, which constructs super cell systems with small atomic displacements. A LAMMPS calculation is performed on the displaced systems to evaluate the atomic forces on each atom without relaxing. The measured atomic forces are then passed back to phonopy, which computes force constants for the system. http://phonopy.github.io/phonopy/interfaces.html
