Phonopy tolerance
WebphonoLAMMPS has been designed to have a very similar python interface to phonopy. For this reason the python objects generated by phonoLAMMPS can be used with phonopy functions. The procedure to obtain the force constants from LAMMPS forces is the following: Loading phonoLAMMPS module from phonolammps import Phonolammps WebJul 19, 2024 · Phonation Threshold Pressure is a fairly easy concept to grasp.

WebA convenient way is to use Phonopy to generate the supercell (SPOSCAR) to be used in the MD. $ phonopy -d --dim="2 2 2". Alternativelly, DynaPhoPy can be used to generate the supercell for either VASP or LAMMPS. The generated supercell is written in POSCAR or LAMMPS data format respectively. VASP: WebJul 8, 2024 · When phonopy (or any similar calculation technique) finds displacements in the cell based on symmetry, the idea is to see how the displacement of certain ions affects the forces on every ion within the cell. We must then take care that the displaced ions don't affect themselves i.e. the effect of their displacement doesn't interact with itself.
