[QE-users] Question for produced number of k-points

[Hüseyin Yasin Uzunok]

Dear community,

I have got a question of the produced k-point numbers in the QE program.
When I use kpoints.x, I have obtain below results;

     *    2 = cubic f (fcc)      9 = orthor base-cent. *
     *    3 = cubic i (bcc)     10 = orthor face-cent. *

     # of k-points   ==    50  of   512


On the other hand when I tried to calculate a similar hexagonal material
that is given in the attached file, it gave 60 k-points instead of 50. This
has happened time to time, but I could not figure how to overcome it. Is
there anyone know the reason or how to overcome it?

Thanks in advance.
