Geometry  User Provided Optimized Optimized Optimized
Non-Bonded Interactions Bonds Rule Based:

Parameters are asigned from existing parameters with a set of rules based on atom types and geometry.

Hessian Based:

Force constant are calculated from the QM potential. New parameters are created when no suitable parameters exists.

Error recordedSemi-empirical geometry optimisation failed. The most likely cause is that either: (1) the geometry was inappropriate; (2) the number of hydrogen atoms or the net charge was inappropriate. Details: *** CHECK YOUR INPUT CHARGE AND MULTIPLICITY (seems to only fail on step 1)

ATB Pipeline Setting

Access to this feature is currently restricted

The maximum QM level is computed using the ATB Pipeline atom limits but can be manually increased on a case by case basis.
