<br>
Despite I am using gaupbe as hybrid functional thinking it still give me the error:<br>
<br>
Error in routine electrons (1):<br>
dexx is negative! Check that exxdiv_treatment is appropriate for the system<br>
<br>
is there any way to fix this problem and having a hybrid calculation for my systems?<br>
could it be because I am running gamma point calculation?<br>
<br>
Cheers<br>
