Dear Usrers,

I want to perform a LDA+U calculations for a ternary, composed of three atoms. 

I give you in this mail the case.inorb and case.indmc, introduced to to that.

When I calculate DOS or BS for lda+u, the results are the same for lda. I have
done the calculation for a binnay, by changing of course the number of atoms
in the case.inorb and case.indmc, and I have observe a difference between the
lda+u and lda calculations.

Please can some one help me, if I have errors in the case.inorb or case.indmc.

my ternary is in supercell of 2x2x2 for zinc blend structre, and it is a spin
polarized system.
