ni3al結(jié)構(gòu)優(yōu)化
|
|
建立了ni3al模型，進行結(jié)構(gòu)優(yōu)化，最后兩個顯示yes，但前兩個沒顯示yes,大家看一下計算設(shè)置及結(jié)果對不對？ Job started on host SC-201708120030 at Tue Sep 19 22:21:21 2017 +-------------------------------------------------+ | | | CCC AA SSS TTTTT EEEEE PPPP | | C A A S T E P P | | C AAAA SS T EEE PPPP | | C A A S T E P | | CCC A A SSS T EEEEE P | | | +-------------------------------------------------+ | | | Materials Studio CASTEP version 2017 | | Ab Initio Total Energy Program | | | | Authors: | | M.
