[Pw_forum] Calculating number of bands

[Shaptrishi Sharma]

Hi there,

I would like to calculate the number of bands for my system with 300 atoms.
What I used to do earlier was I multiplied the total number of atoms with
the valency and then divide the total number of bands by two in order to get
the valence band numbers, but now when I following this method, it is
showing me that 'too few bands'.

is there any other method also?

can anyone please give give any suggestions

Thanks and regards
