7.6.17.34.8. Drift_Diffusion

Syntax: Species Diffusion [{of} SpeciesName] = Drift_Diffusion ()
Scope: Aria Material
Summary: Drift diffusion model for charged plasma species.
Description: The flux takes on the following form, $\mathbf{J} = -D \nabla C - z \mu C \nabla V$ , where D is the species diffusivity, C the species concentration, $\mu$ the species mobility, z the species valence, and $-\nabla V$ the electric field.
