正在用HSE06,但是算NSCF時(shí),出現(xiàn)

這種錯(cuò)誤如何處理?

雜化泛函不支持非自洽,如果是要算態(tài)密度的話直接使用稍大k點(diǎn)自洽直接分析就行。
非常感謝回復(fù)!
好的。 你是意思是直接增加K point 算SCF 對(duì)嗎?
那對(duì)于band struture 怎么辦呢?
謝謝!
有可能也需要像VASP那樣,產(chǎn)生bandstr對(duì)應(yīng)的k點(diǎn),然后這些k點(diǎn)也以0權(quán)重加入,進(jìn)行自洽計(jì)算,最后再提取數(shù)據(jù)。不過(guò)我吃不準(zhǔn)有沒(méi)有更簡(jiǎn)便的做法
,
好的 。非常感謝!
