Thank you for reply. I changed the DIELC value from 1 (default) to 4 then the
failiar vanished for most molecule minimization running. But there are still the
same problem with few others. I am curious how this DIELC affects the running.
Maybe I need to change some basic parameters instead of only this DIELC value.
Thanks.
