Trait Implementations

impl Chemical for Fick

impl Clone for Fick

fn clone(&self) -> Fick

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Fick

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

Formats the value using the given formatter.

impl Diffusion for Fick

fn potential( &self, concentration_gradient: &ConcentrationGradient, ) -> Result<Quantity<MolarFlowRateConcentrationDensity>, ConstitutiveError>

u(\nabla c) = \frac{1}{2}D\nabla c\cdot\nabla c

fn flux( &self, concentration_gradient: &ConcentrationGradient, ) -> Result<MolarFlux, ConstitutiveError>

\mathbf{J}(\nabla c) = -D\nabla c

fn tangent( &self, _concentration_gradient: &ConcentrationGradient, ) -> Result<MolarFluxTangent, ConstitutiveError>

\frac{\partial\mathbf{J}}{\partial\nabla c} = -D\mathbf{I}

type Balance = MolarFlowRate

The balance law the flux enters.
