[Pw_forum] problem LDA+U with Cr ( In tabd.f90 )

[Matteo Cococcioni]

Dear Yukihiro,

yes this is exactly what you should do. you should also update 
set_hubbard_l.f90 and put Cr in the same group
of Fe and Ni. This is needed so that the code knows that the Hubbard 
orbitals of Cr are the d ones (l = 2).

Regards,

Matteo
