HSE band structure

#1 Post by ashwin » Mon Dec 21, 2009 9:25 pm

I did a self-consistent calculation with the HSE functional and now I want a band structure plot. Is the procedure the same as that for a regular LDA/GGA calculation or are there special tags that need to be set for HF type calculations? My INCAR is:

ICHARG = 11
ISTART = 0
ENCUT = 500
ISMEAR = 0
SIGMA = 0.05
LHFCALC = .TRUE.; HFSCREEN = 0.2
ALGO = Damped; TIME = 0.4

and I have the usual strings of k-points along directions of interest in the KPOINTS file. The OUTCAR has a warning:
"Your generating k-point grid is not commensurate to the symmetry of the lattice. This can cause slow convergence with respect to k-points for HF type calculations
suggested SOLUTIONS:
) if not already the case, use automatic k-point generation
) shift your grid to Gamma (G) (e.g. required for hex or fcc lattice)"

Presumably this is to be ignored when k-points are being set by hand?

Thanks!

:(
I encounter the same problem.
I would be grateful if somebody can offer his/her kind assistance.

go to thread "HSE06 band structure" and look for the admin's post
