PEAD routines and k-mesh symmetry
Posted: Mon Apr 08, 2013 5:18 pm
Dear all,
I am trying to perform a calculation of the macroscopic polarization with the PEAD routines (LCALCPOL = .TRUE.) for a hexagonal lattice. I want to skip the Gamma point in the k-mesh so it is not included in the integration. When I do that, VASP complains about the symmetry of the k-mesh and skips the calculation of the polarization.
Is there any way to perform this calculation? Will I be able to carry it out if I choose an orthorhombic-equivalent supercell instead of the hexagonal unit cell?
Thanks,
Miguel
