WebThe following command options can be used for all interface modes. They work similarly to those for phonopy script. --dim --mp, --mesh --band --pa, --primitive_axis --readfc --band_points --nac --factor --nomeshsym -p -c -s, --save -o Currently --pa="auto" works but --band="auto" doesn’t. 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.

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 best advice is to test it. E.g. if you study BCC or FCC metals, 3x3x3 (meaning 27 atoms in the supercell) is usually reasonable. I believe that 1x1x1 supercell is too small.
