[Pw_forum] LDA+U

[ali kazempour]

Dear all
My results after doing LDA+U is very strange for isolated Ti atoms. For d(alpha)/d(n) I see discontinuities .is our result true? And is any way to correct that?
Another question:If our calculation for U instead in the bulk,  would be done in big supercell, Do I get different value for U or both are same?
thanks  a lot
