Dear all,
I am a new user of wanner90. I want to konw what is the the criteria of the converged spread? Or how much the spread reached that we could say it converged. For example, if we have N atoms in a big cell, and every atom has one spread, and the final spread is sum of the N spread for every atom. My question is: th criteria is the final spread must be smaller than a
4 agntrum or each spread of the N atoms smaller than 4?
