[Pw_forum] band structure, can't I use hybrid functional?

[xirainbow]

Dear  Davide:
            I have a tip to do band calculation for band with HSE
hybrid functional.
            1:do scf calculation on a regular k-mesh (for example
4*4*4) and save charge density and wavefunction.
            2: write the k mesh by hand:  Add additional k points to
the regular k-mesh and set the weight of these k point to zero.
            3: do scf calculation again.

            You can find more information at here:

            It is HSE band calculation procedure using VASP.
