The External Surface Charge Accumulation node implements the boundary condition
where ρs is the solution of the following distributed ODE on the boundary:
where n · Ji is the normal component of the total ion current density on the wall and
n · Je is the normal component of the total electron current density on the wall, which are feature inputs.
The Material type setting decides how materials behave and how material properties are interpreted when the mesh is deformed. Select
Solid for materials whose properties change as functions of material strain, material orientation, and other variables evaluated in a material reference configuration (material frame). Select
Nonsolid for materials whose properties are defined only as functions of the current local state at each point in the spatial frame, and for which no unique material reference configuration can be defined. Select
From material to pick up the corresponding setting from the domain material on each domain.
