IDIPOL=3
Posted: Thu Apr 16, 2009 8:32 am
Dear VASP users,
I have a question. I am trying to optimize structure of PdO(101) surface oxide over Pd(100) and I am using mirror sufraces. My INCAR file looks like:
ENCUT = 400.000
PREC = NORMAL
ISPIN = 1 non-spin polarized calculation
NELM = 400; NELMDL= 0 # of ELM steps
EDIFF = 0.1E-03 stopping-criterion for ELM
Ionic Relaxation
EDIFFG = 0.1E-02 stopping-criterion for IOM
NSW = 200 number of steps for IOM
IBRION = 2 ionic relax: 0-MD 1-quasi-New 2-CG
POTIM = 0.5 time-step for ion-motion
ISIF = 2
GGA = 91
VOSKOWN = 1
ISYM = 0
ISMEAR = 1
SIGMA= 0.2
IDIPOL = 3
Electronic Relaxation 2
IALGO = 48 algorithm
LWAVE = F
LCHARG = F
LREAL = T real-space projection
NSIM = 4
NPAR = 4
LPLANE = T
LSCALU = F
My OSZICAR looks normal but when I do "grep F OSZICAR" I get somethin like this:
1 F= -.19545900E+03 E0= -.19541967E+03 d E =-.195459E+03

So, my question is: is there a mistake in my INCAR file? Second, if I use mirror surfaces do I need to use IDIPOL=3 or if I use IDIPOL=3 do I need mirror surfaces?!
Thank's. I will greatly appreciate any answer!
