标题: 求助:优化含镱(III)配合物遇到的不能收敛并异常中断的现象
具体情况:我在跑一个含镱(III)配合物的优化任务,输入文件为:
!  B3LYP  D4  DEF2-TZVP  OPT

%pal nprocs 14 end
%maxcore 1300

* xyz 0 2
   <原子坐标>
程序异常中断后打开.out文件查看发现,SCF未能收敛(原文是:”SCF NOT CONVERGED AFTER 1630 CYCLES“)。接下来(直至.out文件末尾)的输出内容如下:

此外,在输出文件所在的文件夹中,ORCA还给了<输入文件的名字>_atom70.bibtex/out/property.txt/densities/densitiesinfo系列文件,这些文件我从未在跑其它任务时遇到过。

我想请教的问题是:
1. 自洽场未收敛是因为引入了镱且基组选择不恰当吗?如是,应该怎么更改?
2. 这个输出文件中的内容是什么意思?除了自洽场未收敛还表明了有什么其它的错误吗?
3. 为什么会出现_atom70系列的文件?

当前基组用得没有不合理。基组是否合理和SCF是否容易收敛没必然关系。

使用ORCA时遇到SCF不收敛的问题的话,我一般先尝试“SlowConv”关键词,再尝试“VerySlowConv”关键词。如果用了“VerySlowConv”关键词后仍然不收敛的话,就改变初猜。ORCA默认的初猜是PModel,我会改成HCore、Hueckel、PAtom初猜。
