[Pw_forum] G-vector in scf calculation

[Tram Bui]

Dear QE Users,
     I have an scf calculation on a zinc blend system with k-mesh 3x3x3
(automatic). And I obtained a G-vector value of around 120,000. Would
anyone please give me some information on what the G-vector value
represents? and is there a relationship between the k-point and G-vector?

Regards,
