Trait Implementations

impl Clone for Linear

fn clone(&self) -> Linear

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Linear

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Diffusion for Linear

fn potential( &self, potential_gradient: &ElectricField, ) -> Result<Quantity<EnergyDensity>, ConstitutiveError>

u(\nabla\phi) = \frac{1}{2}\varepsilon\nabla\phi\cdot\nabla\phi

fn flux( &self, potential_gradient: &ElectricField, ) -> Result<ElectricDisplacement, ConstitutiveError>

\mathbf{D}(\nabla\phi) = -\varepsilon\nabla\phi

fn tangent( &self, _potential_gradient: &ElectricField, ) -> Result<ElectricDisplacementTangent, ConstitutiveError>

\frac{\partial\mathbf{D}}{\partial\nabla\phi} = -\varepsilon\mathbf{I}

type Balance = Charge

The balance law the flux enters.
