Hi, on the GW first tutorial, it is stated at the start that: Note that, unlike standard band structure calculations, here the KS states must be computed on a regular grid of k-points. (This limitation is also present with hybrid functional calculations). Does that mean it is mandatory to use th…

Hi, Have you tried? I would say it should work. kprlatt produces regular k-point grids, which should be ok. However, I would advise you not to use it. The GW calculations scale nastily wrt to the k-point grid. So it is in general a good policy to keep full control of the k-point grid. Best, F…
