Any suggestions! I'm pussled by this problems for long time! But I don't know how to deal with it. Best wishes!

Hi there,

try playing with this set of parameters:

AMIX = 0.2 ! linear mixing parameter
BMIX = 0.01 ! cutoff wave vector for Kerker mixing scheme
AMIX_MAG = 0.8
BMIX_MAG = 0.01
NELM = 500 ! Maximum number of electronic SC steps
NELMDL = -20 ! Number of NON-selfconsistency steps (negative value: delay only for the start-configuration)

Hth,

alex

Thank you! I will try it!

Thank you for your reply!

It doesn't work!

It does not work! The energy is still very high.

Hi there,

sorry to hear. Please check also the structure. Is it ok? Are there two atoms on the same position? Is the cell size right? And so on.
You may also change the mixing parameters.

Cheers,

alex
