WebFirst, you need to create a phonopy input file with, e.g., ANIME = 0.5 0.5 0 . After running phonopy with this input file, you get anime.ascii that contains all phonon modes at the q … Web(The Phonopy‘s default is 51 Points between two high symmetry points) More details could be seen at Click HERE If the false frequencies still exists,change the " phonopy -d --dim="a a 1" ".Whether to take the larger or the smaller often depends on experience!
How to perform phonon dispersion calculations using VASP?
WebApr 23, 2015 · Dear Pratik, the cell size ('dim') is a parameter and one should check convergence with respect to its value; which also depends on the system as well. So the … Webphonopy -d --dim="2 2 2" -c POSCAR-unitcell use –dim=”4 4 4” if your unit cell is primitive. After that, in each folder: cp SPOSCAR POSCAR Using the following INCAR, we do a single step calculation using VASP to measure linear response of the system when 3 ions are displaced in 3 mutually perpendicular directions. how many motorways in the uk
