The Interlayer Connection is available both for boundaries, and edges. In both cases it removes for the selected layers, the potential gradient in the perpendicular direction (in the direction of the
extra dimension). The layers will become electrically connected, and the top and bottom of all involved layers will have the same potential. Multiple
Interlayer Connection features can be applied to create groups of connected layers.
An Interlayer Connection on a single layer can be used to locally convert the full 3D formulation into an in-plane conservation problem. For thin highly conductive layers, this is numerically more stable.
