[QE-users] Spin-polarized scf calculation without spin-orbit contribution

[Hüsnü Kara]

Dear Rebeza and Hüseyin,

My first e-mail was mistake that there were no lines like following. 

 noncolin = .true
 lspinorb = .true

The code advices me to add these two lines.

Best Regards,

Dear if you are performing non-colinear calculation (noncolin = .true.), you must use SO coupling and the tag nspin=4.

Dear All, 

I want to make the scf calculation which is spin-polarized without spin-orbit contribution. 

When I try it like following: 

&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&& 
&control 
calculation = 'scf' 
pseudo_dir = '/truba/home/.../qe-6.0/pseudo/' 
/ 
&system 
ibrav = 0 
nat = 128 
ntyp = 4 
starting_magnetization(1) = 1 
starting_magnetization(2) = 1 
starting_magnetization(3) = 1 
starting_magnetization(4) = 1 
nspin = 2 
occupations = 'smearing' 
smearing = 'gaussian' 
degauss = 0.01 
ecutwfc = 300.0 
noncolin = .true 
lspinorb = .true 
/ 
&electrons 
diagonalization = 'david' 
conv_thr = 1.0d-4 
/ 
K_POINTS automatic 
1 1 1 1 1 1 
CELL_PARAMETERS bohr 
...... ...... 
ATOMIC_SPECIES 
...... ...... 
ATOMIC_POSITIONS crystal 
...... ...... 

&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&& 

The code gives error and enforces me to make the scf calculation with spin-orbit coupling. 

Please could you help me? 

Best Regards,
