标题:
Molcas 优化激发态是总是出现The limit of loop iterations提示
Molcas在优化分子激发态好几次最后总是出现--- Stop Module: slapaf at Wed Dec 7 16:56:06 2022 /rc= _CONTINUE_LOOP_ ---
--- Stop Module: auto at Wed Dec 7 16:56:06 2022 /rc= _CONTINUE_LOOP_ ---
--- Module auto spent 20 minutes and 11 seconds
*** The limit of loop iterations has been reached
--- Stop Module: auto at Wed Dec 7 16:56:06 2022 /rc= _NOT_CONVERGED_ ---
--- Module auto spent 20 minutes and 11 seconds
想问一下老师可能是什么原因

Molcas默认的优化步数时50步,优化了50步结构还没收敛就退出了,所以你可以用最后的结构继续优化,为了防止这种现象发生,在输入文件里面把优化步数加大即可,具体做法是在
>>>>>>>>>>>>> DO WHILE <<<<<<<<<<<<<
这一行的前面加上:
>>> EXPORT MOLCAS_MAXITER=300
用这个来控制优化步数的多少。
