INPUT

INCAR - 0 ionic relaxation step (actually it calculates 1F step)

SYSTEM = YSZ +VAC Calculation (neutral)
ISTART = 0
ISMEAR = 0
IBRION = 2
ALGO=Normal
LREAL= Auto
NPAR = 4
NSIM = 4
NSW    =     0

POSCAR - use the coordinates of relaxed system, which is result of the above section, 'VASP Computing Bulk Modulus of YSZ'.
