Title: TS searching - problem with hessian (macroiterations)
Post by: yasmeen on May 26, 2020, 10:42:31 AM
During TS searching, to improve procedure  I put hssfreq 3 in $statpt. To make it less time-consuming I added in control $les all 1. But in some cases it failed because 25 macro-iterations are not enogh to converge. I changed it to 35 but it didn't help neither.
What is possible reason of it and what could be a solution?
I haven't faced with such a problem before.
Thank you for any help.
