Is relaxation with different AEXX allowed in VASP?

#1 Post by Vahid Askarpour » Tue Nov 08, 2011 2:18 am

Dear VASP Users,

I have done Exact Exchange HF-type calculations at the electronic level with VASP. However, the calculation starts with a WAVECAR from a pre-converged DFT run. I was wondering if there was a way to relax the structure with the Exact Exchange (say AEXX=0.25) and use this WAVECAR for the HF-type calculations. I have tried the following INCAR but VASP did not relax the system. It simply proceeded to do HF-type calculation.

System = sample1
PREC=Normal
ENCUT=400
LREAL=.FALSE.
ISMEAR=0; SIGMA=0.1
IBRION=2
NFREE=20
POTIM=0.5
ISIF=3
NSW=300
EDIFF=1E-06
EDIFFG=1E-04
NELMIN=4
PSTRESS=100
NPAR=32
NBANDS=64
LHFCALC= .TRUE.
PRECFOCK=N
ALGO=Normal
IMIX=1
AMIX=0.2
AEXX=0.25
MAXMIX=40

I'd appreciate any hints.
Vahid
