INCAR

PREC = Normal    ! standard precision 
ENMAX = 400      ! cutoff should be set manually
ISMEAR = 0 ; SIGMA = 0.1
IBRION = 1       ! use DIIS algorithm to converge
NFREE = 2        ! 2 independent degrees of freedom
NSW = 10         ! 10 ionic steps
EDIFFG = -0.02   ! forces smaller 0.02 A/eV

KPOINTS

Gamma-point only
