Dear wien2k users
  I want to run LDA+U for Gd2Al .* *
**
 In structure of Gd2Al we have three original atoms and we must use add
position for all of atoms because we have 12 atoms in unit cell , then
atomic index for 4 atoms is similar so, i think ,we front this error on
case.outputorbup :
 *Conflict in atom orb. number: lorb 3 ne ll 0*
the structure file is similar to this :

*ATOM -1: X=0.17000000 Y=0.25000000 Z=0.07000000
MULT= 4 ISPLIT= 8
-1: X=0.33000000 Y=0.75000000 Z=0.57000000
-1: X=0.83000000 Y=0.75000000 Z=0.93000000
-1: X=0.67000000 Y=0.25000000 Z=0.43000000
& ...*

**

i exam two way of writting for case.inorb & case.indm :

one of them is :

 * **1 8 0 nmod, natorb, ipr
PRATT 1.0 BROYD/PRATT, mixing
1 1 3 iatom nlorb, lorb
1 1 3 iatom nlorb, lorb
1 1 3 iatom nlorb, lorb
1 1 3 iatom nlorb, lorb
2 1 3 iatom nlorb, lorb
2 1 3 iatom nlorb, lorb
2 1 3 iatom nlorb, lorb
2 1 3 iatom nlorb, lorb
1 nsic 0..AFM, 1..SIC, 2..HFM
0.22 0.00 U J (Ry) Note: we recommend to use U_eff = U-J and J=0
0.22 0.00 U J
0.22 0.00 U J
0.22 0.00 U J
0.22 0.00 U J
0.22 0.00 U J
0.22 0.00 U J
0.22 0.00 U J*

**
and another is:

 * **1 8 0 nmod, natorb, ipr
PRATT 1.0 BROYD/PRATT, mixing
1 1 3 iatom nlorb, lorb
2 1 3 iatom nlorb, lorb
3 1 3 iatom nlorb, lorb
4 1 3 iatom nlorb, lorb
5 1 3 iatom nlorb, lorb
6 1 3 iatom nlorb, lorb
7 1 3 iatom nlorb, lorb
8 1 3 iatom nlorb, lorb
1 nsic 0..AFM, 1..SIC, 2..HFM
0.22 0.00 U J (Ry) Note: we recommend to use U_eff = U-J and J=0
0.22 0.00 U J
0.22 0.00 U J
0.22 0.00 U J
0.22 0.00 U J
0.22 0.00 U J
0.22 0.00 U J
0.22 0.00 U J*
Note that i only used LDA+U for Gd and we have two kind of Gd in structure
so we must use LDA+U for 8 atoms .

if you need more information you can see attach .

 Please help me!

 Best Regard,

osaty
