QMMM interface
Two-level hybrid calculation (QM/MM, QM/QM', ...) using a subtractive scheme similar to ONIOM[1,2]. The QMMM tutorial shows how to setup a calculation.
Keywords
- qmmm_core
- qmmm_qm_charge
- qmmm_cut_bonds
- qmmm_rename_residues
- qmmm_add_ter
- qmmm_geometry_only
- polarized
- atomic_charges_read
- qmmm_remove_charges
- microiterations
The methods of calculations are specified in subsections
- qmmm_method_hi
- qmmm_method_lo
The subsections
- qmmm_method_lo_mmpart
- qmmm_method_lo_qmpart
allows to modify the MM calculations of the complete system and QM region separately. Keywords used here are added to or override the ones in qmmm_method_lo.
