I have a technical question. I am performing excited state calculations using VASP version 5.4.4. This is my INCAR file content:
Code: Select all
# Header
SYSTEM = nve_asym
# Restart option
ISTART = 1 ! restart calculations

ISYM = 0 ! for hybrids ISYM = 3 is suggested
ISPIN = 2 ! spin polarized calculations
NELECT = 2046 ! negatively charged state (510*4 + 5 + 1 = 254)
NBANDS = 1056 ! 2112 orbitals
ISMEAR = -2 ! partial occupancies are read, and kept fixed throughout run.

FERWE = 1021*1.0 1*0.0 1*1.0 1000*0.0
FERDO = 1024*1.0 1000*0.0
# Geometry optimization
NSW = 70 ! maximum number of ionic steps
IBRION = 1 ! quasi-Newton
ISIF = 2 ! relax ions
EDIFF = 1e-4 ! break condition for the electronic SC-loop
EDIFFG = -0.001 ! stop if all forces are smaller than |.| eV/A

ALGO = Fast ! blocked Davidson iteration scheme
PREC = Normal ! 1.3ENCUT

LHFCALC = .TRUE. ! performs Hartree-Fock type calculations
HFSCREEN = 0.2 ! range separation parameter in hybrid functionals
AEXX = 0.25 ! 1/4 of the exact exchange is used
