WARNING:The distance between some ions is very small

#1 Post by vasp2010 » Wed Oct 06, 2010 3:23 am

HI All
I want to do some relaxtion about Gd2Zr207 pyrochlore. I chose a primitive cell. However, the result tell me " The distance between some ions is very small,please check the nearest neigbor list in the OUTCAR file.
I HOPE YOU KNOW, WHAT YOU ARE DOING".
I do no idea about that.
Please could you help?
I appreciate it.

Thanks in advance!
Those are INCAR and POSCAR .

ISTART = 0 ; ICHARG = 2
ISMEAR = 0 ; SIGA = 0.1
LREAL = Atuo
PERC = Accurate
ENCUT = 400
ALGO = 48
NSIM = 4
LPLANE = .TRUE.
NPAR = 4
ALGO = Very_Fast
LSCALU = .FALSE.
NSW = 60
IBRION = 2
ISIF = 3
SYSTEM = Ga2Zr207

Atom number 10 and atom number 11 have the same coordinates:

0.345000 0.905000 0.905000

Please, make it a custom to check your geometry in a viewer before you use it.

Cheers,
/Dan

thank you very much.
I am a newcomer on VASP.
I am careless.
I want to say "谢谢“
