The Floating Potential subnode is available from the context menu (right-click the Single-Turn Coil parent node) or from the Physics toolbar, Attributes menu. It can be used to model a boundary at a constant, unknown, coil potential. If applied on multiple non connected boundaries, it models an electrical connection between them. The feature can be used for coils constituted of multiple series-connected domains. Unlike the corresponding feature in other AC/DC physics, this feature only allows zero total current flowing in the boundary. This is to ensure that all currents in the coils are excited by the Boundary Feed or Gap Feeds and are properly accounted for in the postprocessing variables.
