Definition of regions for an incomplete computation
Introduction
The simplified or incomplete computation is a computation carried out under the following conditions:
- the computation is accomplished without taking into account of the current density in the structure
- the structure introduced in the electrolyte is represented by means of boundary conditions
Volume region
Volume regions are gathered in the table below.
| A volume region… |
is a material region which enables the modeling… |
|---|---|
| electrolytic conducting | of a conducting medium (resistivity ρ) |
| inactive | of an insulating medium |
Face region
Face regions are gathered in the table below.
| A face region… | is a BC that enables one to impose… |
|---|---|
| electrochemical interface |
conditions at the interface “electrolyte – cathode” by the intermediate of a polarization law |
| imposed potential |
a potential (varying formula / spatial formula) (sacrificial anode) |
| imposed normal current density |
a normal current density* (varying formula / spatial formula) (active anode) |
is directed from the face region towards the
electrolyte.Line region
Line regions are gathered in the table below.
| A line region … | is a BC that enables one to impose … |
|---|---|

a radial current density* (varying formula / spatial formula) (active anode) |
is directed from the line region towards the
electrolyte.Point region
Point regions are gathered in the table below.
| A point region… | is a BC that enables one to impose… |
