[求助] 使用B3LYP来计算TiO2之bulk及surface的INCAR和K点选择

我有试着看过VASP说明文件
但是能量始终无法收敛
附上我的INCAR和K点
INCAR:
NWRITE =    2
PREC = medium
ISTART =    0
ICHARG =    2
ISPIN  =    1
ENCUT  = 300
ISYM =    2
ISMEAR = 0
SIGMA  = 0.1
IALGO  =    48
LDIAG  =    T
EDIFF  = .1E-04
EDIFFG = .2E-03
NSW =  500
IBRION =  2
ISIF =  3
LDIPOL = .TRUE.
LVHAV  = .TRUE.
LELF = .TRUE.
LWAVE  = .FALSE.
LCHARG = .FALSE.
PRECFOCK = M
LREAL  = Auto
LHFCALC = .TRUE.
ALGO = D
TIME = 0.5
GGA = B3
AEXX = 0.2
AGGAX = 0.72
AGGAC = 0.81
ALDAC = 0.19

KPOINT:

IBRION=2 适合初始结构优化时的优化
IBRION=1 有助于后期结构收敛得更快
实在不行试下prec = low
最后看看初始结构还有优化时的结构有没有出错吧
可以贴上你的OSZICAR看看
