The Electrode, Shell (els) interface (
), found under the
Electrochemistry branch (
) when adding a physics interface, models electric current conduction in the tangential direction on a boundary.
When this physics interface is added, these default nodes are also added to the Model Builder—
Electrode,
Electric Insulation (the default edge or point condition), and
Initial Values. Then, from the
Physics toolbar, add other nodes that implement, for example, edge or point conditions and current sources. You can also right-click
Electrode, Shell to select physics features from the context menu.
The Label is the default physics interface name.
The Name is used primarily as a scope prefix for variables defined by the physics interface. Refer to such physics interface variables in expressions using the pattern
<name>.<variable_name>. In order to distinguish between variables belonging to different physics interfaces, the
name string must be unique. Only letters, numbers, and underscores (_) are permitted in the
Name field. The first character must be a letter.
The default Name (for the first physics interface in the model) is
els.
The dependent variable (field variable) is for the Electric potential. The name can be changed but the names of fields and dependent variables must be unique within a model.
