[Pw_forum] Generating full BZ electronic velocities from the irreducible wedge velocities

[Vahid Askarpour]

Dear QE Users,

I would like to apply symmetry to irreducible wedge electronic velocities (which I have and is a 1x3 vector) to generate the electronic velocities for the whole BZ. The symm_base.f90 file contains the symmetry elements and operations but I don’t know how to apply it to the above problem. Does anyone know if there is an easy way to do so?

Thank you,
