The G-Fleur add-on
G-Fleur is a realization of the Green function embedding technique employing the FLAPW basis-set. It is an independent computer program but its development refers directly to the FLEUR code.

Features:
Complex Bandstructures of bulk materials
Surfaces between semi-infinite bulk and vacuum regions
Interfaces between semi-infinite bulk leads
Electronic transport in equilibrium and out of equilibrium
As the code is based on FLEUR many of the FLEUR features can be carried over. For example:

Non-Collinear Magnetism
Spin-orbit interaction
LDA+U
More information
That's what G-Fleur is providing: J.E. Inglesfield, A method of embedding J. Phys. C 14, 3795 (1981). D. Wortmann, H. Ishida and S. Blügel, Phys. Rev. B 66, 075113 (2002) and Phys. Rev. B 65, 165103 (2002).

I want to apply an installation package about the G-Fleur，where can I find it？

Thanks a lot for your interest in the G-FLEUR add on. Unfortunately, this code has not been maintained for several years and thus is not compatible with recent FLEUR versions. I hope I will find some time (sometime) to work on it again.

Best regards

Daniel
