3.12.3. `horton.part.hirshfeld` – Hirshfeld partitioning¶

class horton.part.hirshfeld.HirshfeldWPart(coordinates, numbers, pseudo_numbers, grid, moldens, proatomdb, spindens=None, local=True, lmax=3)¶

Bases: horton.part.hirshfeld.HirshfeldMixin, horton.part.stockholder.StockholderWPart

Arguments: (that are not defined in WPart)

proatomdb: In instance of ProAtomDB that contains all the reference atomic densities.

__getitem__(key)¶

__init__(coordinates, numbers, pseudo_numbers, grid, moldens, proatomdb, spindens=None, local=True, lmax=3)¶

Arguments: (that are not defined in WPart)

proatomdb: In instance of ProAtomDB that contains all the reference atomic densities.

clear()¶: Discard all cached results, e.g. because wfn changed

compute_pseudo_population(index)¶

do_all()¶: Computes all properties and return a list of their keys.

do_charges(instance)¶

do_density_decomposition(instance)¶

do_dispersion(instance)¶

do_hartree_decomposition(instance)¶

do_moments(instance)¶

do_partitioning(instance)¶

do_populations(instance)¶

do_prosplines()¶

do_spin_charges(instance)¶

eval_proatom(index, output, grid=None)¶

eval_spline(index, spline, output, grid=None, label=’noname’)¶

fix_proatom_rho(index, rho, deriv)¶

Check if the radial density for the proatom is correct and fix as needed.

Arguments:

index: The atom for which this proatom rho is created.
rho: The radial density
deriv: the derivative of the radial density or None.

get_grid(index=None)¶

Return an integration grid

Optional arguments:

index: The index of the atom. If not given, a grid for the entire system is returned. If self.local is False, a full system grid is always returned.
