H2O vibration

• INCAR

SYSTEM = H2O vibration
ISMEAR = 0   ! Gaussian smearing
IBRION = 6   ! use the conjugate gradient algorithm
NFREE = 2    ! central differences
POTIM = 0.015 ! 0.015 A stepwidth 
EDIFF = 1E-6 
NSW = 1      ! ionic steps > 0

• KPOINTS

Gamma-point only
 1        ! one k-point
rec       ! in units of the reciprocal lattice vector
 0 0 0 1  ! 3 coordinates and weight
