Thanks for raising this š
It's already "fixed" in v1.4.0, so would appreciate if you could try it out and see if it's any better!
presumably there is some handling of TS optimisations that are almost converged?
this is exactly what did happen, if the imaginary mode was still present.
Do you think it's worthwhile adding a keywords.set_max_opt_cycles(num=200)
method to set all of the opt
, low_opt
and opt_ts
keywords maximum number of optimisation cycles ā perhaps it's confusing that opt
doesn't set all of them?!
Describe the bug A NotImplementedError is thrown by the
QChem.py
wrapper when a TS optimisation gets close but does not converge. (Unsure if this counts as a bug or as a feature request)To Reproduce This is the Python script used to submit the calculation:
The error traceback is attached.
TSopt_error.txt
Expected behavior Unsure what other wrappers do here ā presumably there is some handling of TS optimisations that are almost converged? It would be great if a new job were set up, either with an improved TS guess from the higher level method, or if there is still a sensible imaginary frequency at the final geometry of the failed TS search then using that as a guess for the next TS optimisation job.
