DriftDiffusionDoNothingBC
Boundary condition where the flux at the boundary is equal to the bulk dift-diffusion equation
Overview
DriftDiffusionDoNothingBC is an outflow boundary condition where the outflow at the boundary is equal to the bulk dift-diffusion equations.
The outflow is defined as
Where is the outflow normal to the boundary, is the normal vector of the boundary, indicates the advection behavior ( for positively charged species, for negatively charged species and for neutral species), is the mobility coefficient, is the diffusion coefficient, is the density, and is the electric field. When converting the density to logarithmic form and applying a scaling factor of the mesh, the strong form for DriftDiffusionDoNothingBC is defined as
Where is the molar density of the species in logarithmic form and is the scaling factor of the mesh.
