The Electric Currents in Layered Shells (ecis) interface (), found under the AC/DC>Electric Fields and Currents branch when adding a physics interface, is used to compute electric field, current, and potential distributions in thin and thick conductive shells and dielectrics, optionally with an internal layered structure. Inductive effects are assumed to be negligible; that is, the skin depth should be much larger than the studied device. It supports stationary, time-dependent and frequency domain modeling on faces in 3D.

The Electric Currents in Layered Shells interface is very similar to The Electric Currents in Shells Interface. The main difference is the default mode. The Electric Currents in Shells Interface is set to be nonlayered by default, while the Electric Currents in Layered Shells interface is set to be layered by default.
