Dear All,

I try to use vdw-df1 and vdw-df2 functionals on vasp 5.2.12 but fail. I directly copy the kernel to the job directory. My system contains 15 atoms and the error is segmentation fault. If I remove vdw tags, vasp works well. Following is my INCAR and output from vasp. Thank you for your help.

INCAR

SYSTEM=ZnO
ISTART=0
ICHARG=2
ISPIN=2
PREC=Accurate
NPAR=4

NELM=200
ALGO=N
LREAL=.F.
EDIFF=1E-6
LUSE_VDW=.T.
AGGAC=0.0000
GGA=RE

IBRION=2
NSW=200
ISIF=3
ENCUT=420
EDIFFG=-1E-2

ISMEAR=-5
SIGMA=0.1

Sorry, the title should be "vdW-DF problem of vasp".
