ISMEAR = 2; SIGMA = 0.05
for structural opt., andISMEAR = 2; SIGMA = 0.1
for phonon calculations,ISMEAR = -5
for DOS and MAE. -
LREAL
is set toAuto
except for phonon and MAE calculations, where it is set toFalse
. -
EDIFF
is set to1.0e-7
for structure optimization and1.0e-8
for phonon calculations and MAE calculations. -
EDIFFG = 1.0e-4
