GW calculation

#1 Post by corbin » Mon May 23, 2011 7:10 am

Dear all,

I intend to do a GW calculation with vasp 5.2.2. First, I tried the examples Si and BN. The Si calculation finish successfully, but the BN calculation just stuck at calculation initialization, the following is the OUTCAR file:

total amount of memory used by VASP on root node 79781. kBytes
========================================================================

base : 30000. kBytes
nonl-proj : 11866. kBytes
fftplans : 274. kBytes
grid : 1505. kBytes
one-center: 6. kBytes
HF : 25. kBytes
nonlr-proj: 43. kBytes
wavefun : 36062. kBytes

Broyden mixing: mesh for mixing (old mesh)
NGX = 9 NGY = 9 NGZ = 33
(NGX = 24 NGY = 24 NGZ =100)
gives a total of 2673 points

initial charge density was supplied:
charge density of overlapping atoms calculated
number of electron 8.0000000 magnetization
keeping initial charge density in first step


--------------------------------------------------------------------------------------------------------


Maximum index for augmentation-charges 219 (set IRDMAX)


--------------------------------------------------------------------------------------------------------


FEWALD: cpu time 0.00: real time 0.00


then the calculation will no go anymore.

INCAR_DFT

System=GW

ISMEAR=0
SIGMA=0.05

LOPTICS=.TRUE.

ALGO=Fast

NBANDS=160


INCAR_GW0


System=GW

ISMEAR=0
SIGMA=0.05

LOPTICS=.TRUE.

ALGO=GW0

NBANDS=160

NOMEGA=64

NELM=4


Any comments will be appreciated, thank you in advanced!

Hi,

We're sorry that we didn’t answer your question. This does not live up to the quality of support that we aim to provide. The team has since expanded. If we can still help with your problem, please ask again in a new post, linking to this one, and we will answer as quickly as possible.

Best wishes,
