[Pw_forum] Fwd: hybrid preprocessing

[Tommaso Francese]

> Dear all QE users,
> what i would like to know is this: if i want to calculate for instance the DOS of a orthorhombic zirconia, and i want to implement an hybrid functional in scf, e.g. B3LYP, do i have to preprocess “something”, as in EXX_example, or just i force the scf with the hybrid functional and then i directly run the dos.x code? Can anyone help me? And so, can someone briefly explain to me the aim of the preprocessing used in EXX_example? When it is necessary?
