NELM = [integer]
Default: NELM = 60
Description: NELM sets the maximum number of electronic SC (self-consistency) steps.
Normally, there is no need to change the default value: if the self-consistency loop does not converge within 40 steps, it will probably not converge at all. In this case you should reconsider the tags IALGO or ALGO, LSUBROT, and the mixing parameters.
