Syntax
{BACK:Interfaces} Fragmented calculation based on the the Kernel energy method^[1^]. Extensions of the original method include use of polarizing point charges, calculations in full basis of the system and gradient. Related script [geometry_fragmentation] can be used to prepare the input. There is also a [tutorial|Fragmentation tutorial] on how to set up and run a fragmented calculation. !Keywords Specification of the calculation level used for fragments is done in subsection '''fragment_calculation''' * ::fragments:: * ::fragment_charges:: * ::fragmentation_3rd_order:: * ::fragmentation_fullbasis:: * ::polarized:: * ::atomic_charges_read:: * ::charge:: * ::fragmentation_fixed_links:: * ::distributed:: * ::print:: * ::write_interaction_matrix:: * ::fragmentation_fix_grad:: * ::fragmentation_ch_mindist:: !References ^[1^] L.
