vasp ends relaxation before EDIFFG is reached, and weird "num prob" in stdout
Posted: Mon Apr 11, 2011 12:31 pm
Hi,
I hope you can help me with this; I'm trying to relax fcc bulk copper and VASP exits without error messages long before EDIFFG is reached. In the same calculation, "num prob" appears in stdout (but not in OSZICAR).
My k-point mesh is fairly dense (24x24x24 Monkhorst-Pack grid), but since the cell is highly symmetric, I figured that should work...
Here is my INCAR:
SYSTEM = PBE_Cu_bulk_1x1x1
ENCUT = 500.0
ENAUG = 605.4
ISTART = 2
ICHARG = 2
NWRITE = 1
PREC = High
EDIFF = 1.0E-8
EDIFFG = 1.0E-8
LREAL = .FALSE.
POTIM = 0.10
IBRION = 2
ISIF = 3
NSW = 100
NELM = 999
KBLOCK = 10
GGA = PE
ALGO = Fast
ISMEAR = -1
SIGMA = 0.05
NBANDS = 24
And this is the last loop as printed in stdout:

reached required accuracy - stopping structural energy minimisation
writing wavefunctions
It says here that the stopping criterion was reached, but in other calculations the dE value in the line

also went down to EDIFFG which seemed to make sense since it denotes the difference in energy between two steps. Or is that a misunderstanding on my part?
What could have gone wrong here?
