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 … WebPhonopy is an open source package for phonon calculations at harmonic and quasi-harmonic levels.

WebMay 21, 2011 · FC_SYMMETRY imposes acoustic sum rule and force constant symmetry of exchanging a couple of atom indices repeatedly. Increasing number of FC_SYMMETRY setting, these are done the number of times. In the case of VASP, VASP imposes sum rule to forces on atoms inside VASP and we do not need to apply sum rule in phonopy.
