Dear P.

You can find an example file in tests v5/08. Upawu and jpawu are in hartree if the energy unit is not supplied.
A paper describing some aspects of the implementation will be available soon.

Best regards
Bernard Amadon

PGanesh a écrit :
Has anyone done LDA+U calculations using PAW in Abinit? If so I would like to get hold of a sample input file or reference to a possible publication of such a calculation using Abinit. Presently I am getting PbCrO3 to be metallic even at large values of "U" (supposed to be insulator).
Also, I am assuming that the units of "lpawu" and "jpawu" are in Hartrees. Please correct me if I am wrong.


Thanks,

-P. Ganesh
