<p>Hi
everyone,</p>
<p> I have been trying to do ENERGY calculation
for NO+Au(111) system. If I don’t set BS section, the calculation can converge.
But the calculated spin moment is 0, which is unreasonable. So I open BS
section, I can get right spin moment, but SCF doesn’t converged. As a metallic system,
I use diagonalization as convergence algorithm. I tried several mixing methods,
I found the KERKER_MIXING is a relatively better choice. But, the convergence
of this calculation also cannot reach the desired value (1.0E-6), and only
~1E-4 can be reached. I tried to change the value of ALPHA (from 0.2 to 0.005),
but it also doesn’t work. The SCF cycle never converges. Any help would be very
appreciated. Thanks!</p>
<p>Regards,</p>
