[QE-users] Supercell for big G-type antiferromagnetic unit cell

[Tarek]

Dear All

      I am trying to construct 2x2x2 super cell for G-type 
antiferromagnetic calculations. The problem is that the unit cell 
contains 30 independent atoms.

This means that I will have 8X30 = 240 atoms !!!. This is very expensive 
of course.

What do you advise me?

Thanks a lot
