Re: it takes so long, when will it will converge?

Hi,

normally, it will take several dozens of geometry update steps.

To speed up convergence, I'd suggest you to use delocalized
coordinates (DLCs). To this end, add $contrl nzvar=1 $end to
your input and resubmit. Do not forget to update geometry using
the best one (i.e. the one having the lowest energy).

Kind regards,
Alex Granovsky
