H2O molecular dynamics

• INCAR

PREC = Normal    ! standard precision 
ENMAX = 400      ! cutoff should be set manually
ISMEAR = 0 ; SIGMA = 0.1
ISYM = 0         ! strongly recommended for MD
IBRION = 0       ! molecular dynamics
NSW = 100        ! 100 steps
POTIM = 1.0      ! timestep 1 fs
SMASS = -3       ! Nose Hoover thermostat
TEBEG =  2000 ; TEEND = 2000 ! temperature

• KPOINTS

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