用新搭建的一台服务器优化一个CeO2结构,优化过程使用60个核,Material Studio上下载的cif文件,切了1 1 1表面,总共有32个Ce原子、64个O原子,计算前固定了底部三层原子。
优化过程中修改了很多参数,电子步能量始终无法收敛,并且dE降低到10的-2次方后还会跳回到10的4次方及以上,然后计算报错:Error EDDDAV: Cal1 to ZHEGy failed. Returncode = 9 1 10
下面是我的INCAR:其中AlGO试过Normal、Fast、veryfast等,ENCUT最高加到了520 eV,AMIX增加到0.2或者降低到0.05均不能收敛。

恳请大神指路!!!
