SIGSEGV, segmentation fault occurred

#1 Post by zyyin » Sun Dec 13, 2009 12:31 pm

I am running a graphene calculation, but keep getting the following error:
POSCAR found : 2 types and 26 ions
LDA part: xc-table for Ceperly-Alder, standard interpolation
POSCAR, INCAR and KPOINTS ok, starting setup
WARNING: wrap around errors must be expected

As suggested in some websites, it is maybe caused by memory limitation. So, I try a new simple model with only a single Fe atom, but still get a similar error as follows:
POSCAR found : 1 types and 1 ions
LDA part: xc-table for Ceperly-Alder, standard interpolation
POSCAR, INCAR and KPOINTS ok, starting setup

model with Fe atom:
INCAR
SYSTEM =Fe atom
ISART = 0
ENCUT=450.00 ev
NELMDL=5
ISMEAR =0
SIGMA = 0.1

KPOINTS
Automatic mesh
0
Gamma
1 1 1
0 0 0

POSCAR
Fe
15.0
1.00 0.00 0.00
0.00 1.00 0.00
0.00 0.00 1.00
1
Direct
0 0 0

and use potcar_paw.tar as my pseudopotential lib
