Use the Impressed Current Surface node to control the potential difference between a sense s, sense (V) and a reference s, ref (V) potential, which both are defined globally.

The desired potential difference Eimpr (V) is achieved by applying a electrolyte potential constraint on the boundary selection of the impressed current surface, using an added global electrolyte potential dependent variable left to “float” in order to fulfill the control condition.

The node is active if Enable Cathodic Protection Features check box is enabled at the interface node.
