Hi Francesca, As you can see you got charge deficieny, meaning that bands number is not sufficient. You did not specify any occupations keyword, so your system is considered as insulator (or semiconducting) for which only nbnd=(number of valence electros divided by 2) is used. It might be that during relaxation process your system turns to be metallic for which one should use more bands number. So, try nbnd=490/2 + 10= 255 (in &system)
Hope this helps. Bests, Eyvaz. --- Francesca Costanzo <costanzo at ms.fci.unibo.it> wrote: > Thank you Paolo > for your quick answer, > may be the input file can be more self explaining. > By the way the machine where
