Dear Matteo
I decide to go to the common calculation of U for isolated atom.As noted in
refference paper atomic U is? :
Uat = {Etot[d(n+1)] ? Etot[d(n)]} ? {Etot[d(n)] ? Etot[d(n?1])}
this mean that I need to calculate differrent systems with various occupation
of d orbital for i.e Etot[d(10)] and Etot[d(9)] and Etot[d(8)]
for doing this ,is it enough to only change in tabd.f90 the occ_loc from 10 to
9? or should I do? additional modifications?
thanks

dear Ali,
set_hubbard_l doesn't need any change. you can try to set occ_loc to 9
(for Zn) in tabd.f90.
But I suspect that you won't get a big change in your results. maybe not
even if you changed the reference configuration
of the pseudopotential.
just try and let us know.
