Diagram illustrating a cross section of the cylindrical domain used for forward solving. At the center of the domain is present the TREIT probe which sources and sinks currents through electrodes. As the probe is an insulator (except for the electrodes) at the interface of the probe with tissues Neumann boundary conditions are applied imposing no current flow. The interface between electrodes and tissues is described with the Complete Electrode Model, and Neumann boundary conditions are applied to the outer boundary of the domain, as no current enters or leaves the domain.
