The Surface Current Density subnode is available from the context menu (right-click the Transition Boundary Condition parent node) or in the Physics toolbar, click the Attributes menu. It adds a surface current density on upside and downside of the transition boundary.

This subnode is available only when the layer Type on the parent node is set to either Electrically thin layer or Electrically thick layer.

Enter values or expressions for the Surface Current Density on upside Js0u and downside Js0d (SI unit: A/m) coordinates. The defaults are 0 A/m.
