INCAR
- This is the INCAR file for the basic DFT calculation:
- Si_dft_exc
System = Si PREC = Normal ; ENCUT = 250.0 ISMEAR = 0 ; SIGMA = 0.01 KPAR = 2 EDIFF = 1.E-8 NBANDS = 16 LOPTICS = .TRUE. # needed for WAVEDER file LPEAD = .TRUE. OMEGAMAX = 40
KPOINTS
The KPOINTS file will be automatically generated in this example.
