ElectricField
-
class ElectricField : public feasst::ModelOneBody
Apply an electric field along a dimension.
\(U_{ext}(x) = -q E x\)
where \(q\) is the charge of a site, \(E\) is the electric field and \(x\) is the position along a given dimension.
Public Functions
-
void precompute(const Configuration &config)
Precompute model parameters based on existing model parameters.
-
double energy(const Position &wrapped_site, const Site &site, const Configuration &config, const ModelParams &model_params)
Return the energy given the wrapped coordinates, site, config and params.
-
void serialize(std::ostream &ostr) const
Output a serialized version of the existing model.
Arguments
dimension: direction of the electric field (default: 0).
field_strength: external electric field strength in force per charge. The units are assumed to be Volts/Angstrom, where charge is electron charge and energy is in kJ/mol.
