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 … WebPerform a phonon calculation#. Setting up a phonopy calculation is similar to settings up a relaxation (or any other workflow supported by FHI-vibes).To ensure that our physical settings don't change, we will copy the relaxation.in obtained in the previous part of the tutorial to the new working directory and rename it to phonopy.in.Please delete the … daughter son in law wedding card
