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. WebJul 8, 2024 · Using Phonopy this would be completely impossible, as it would require a supercell of size 110,592 (containing 221,184 atoms)! This calculation is in fact possible (and relatively easy), using nondiagonal supercells, which would only require a supercell of size 48 (containing 96 atoms). Disclaimer: I am an author of the nondiagonal supercell …
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).
