Dear Admin:
I compile the VASP5.x for spiral,and add use_enini_without_ldelay to makefile. But with these data below for FCC Fe, we can not get the spin spiral data.

ICHARG = 1
ISMEAR = 0
PREC = High
ENCUT = 400
ENINI=100
EDIFF = 1E-6
VOSKOWN = 1
ISPIN = 2

ISYM = -1
LNONCOLLINEAR = .TRUE.
#LSPIRAL = .TRUE.
QSPIRAL = 0.1 0.1 0.0
LASPH = .TRUE.
MAGMOM = 0 0 0.55 0 0 0.55 0 0 0.55 0 0 0.55

even grep "LSPIRAL" OUTCAR, we get nothing.

So what happens? Does the vasp need another new .F file to compile VASP? Or our input data are something wrong?

Waiting for your answer. Thank you

I have heared that, we should add -Duse_enini_without_ldelay into makefile first, then we should modify one sentence in the file about spiral. So, which file and which sentence should we modify? Thanks a lot
