2d system stoping without any error in OUTCAR

[rudrabanerjee]

Dear all,
I am trying to calculate a 2d molecule, but it is coming out without any error in OUTCAR or stdout (slurm error file is showing seg fault).
My INCAR is:

Code: Select all

ALGO = Fast
ISTART=0
EDIFF = 0.0001
ENCUT = 520
IBRION = 2
ISIF = 4
NCORE=3
ISMEAR = -1
ISPIN = 2
LASPH = True
LORBIT = 11
LREAL = Auto
LWAVE = False
MAGMOM = 37*0.6
NELM = 100
NSW = 99
PREC = Accurate
SIGMA = 0.05

POSCAR:
XCrySDen XSF file

Code: Select all

The add files section is not allowing me to add the other files, so I am adding OUTCAR, vasp.out, slurm_error and full potcar through G-drive.

I will be grateful if you kindly show some way.

Dear rudrabanerjee,

I was not able to reproduce this error so far. Could you please provide the list of libraries and compilers you use?

Here are some things you could try:
- use VASP 6 instead of VASP 5.4.4, if you have access
- it looks like you system is not periodic in x and y directions, so there is no need to sample the k-points along these axis
- perform a calculation with ISPIN = 1 first and then restart the spin-polarized calculation with the converged charge density
- remove NCORE = 3 tag or set NCORE = 1
