calculation for my SiC structure. As I run the " scf" calculation with a
single defect, e.g. interstitial or sustitutional, the lattice parameter of
the unit cell is expected to be stretched. And as I checked, the latt

I hope it is useful.

determine degauss value (smearing width). These options not only use for
metallic systems but also for spin-polarized systems. If the mean of
