Dear PWSCF users,<br>
I have a question about 'mixing_beta'
and 'mixing_ndim'. In one 'scf' calculations, I found it
converges very slowly. The 'estimated scf accuracy' remains
almost a constant in the two subsequent iterations. Do you think
whether it will help if I change 'mixing_beta' or 'mixing_ndim', making
them larger or smaller?<br>
Thank you.<br>
