Connection Point
Use the Connection Point node to define a location for connections (trough one or several external metallic wires) to other locations in the model.
The connection point defines a global potential degree of freedom and sets the local electrode potential to this potential at the feature's point selection. In this way Kirchoff’s first law is fulfilled, with the sum of all electrode currents entering or exiting the point equaling to 0. The global degree of freedom is announced so that it can be used by, for instance, the External Short electrode phase potential condition.
Enable Define reference electrode to also define a reference electrode potential. The reference electrode potential can typically be used by an Impressed Current Point node to actively control the electrode potential at the location of the connection point. Specify the Equilibrium potential of the reference electrode in the corresponding edit field.
This node is available as a subnode to the Edge Electrode or the Sacrificial Edge Anode node. The node is active if Enable Cathodic Protection Features check box is enabled at the interface node.
