WebThis section of the tutorial demonstrates how an existing FCP can be employed in conjunction with phonopy to analyze the thermal properties of a material in the harmonic approximation. Note that this analysis by definition invokes only the second-order force constants and primarily relies on phonopy. Preparations WebTo get the phonon frequencies quickly on the command line simply type the following: grep THz OUTCAR To get an accurate phonon dispersion it is important to perform the force-constants calculation in a large enough supercell. When increasing the size of the supercell it is recommended to decrease the k point density in the KPOINTS file. incognito 2 lighting board
