The Electric Shielding node, available for 3D components, can be used to model a geometrically thin section of shell made of a highly conductive medium. The layer thickness parameter dl specifies the thickness in the direction tangential to the shell, while the thickness in the direction normal to the shell is taken from the physics interface or, if present, from a Change Shell Thickness node.

The layer has an electrical conductivity of σ and a relative permittivity of εr.

The default Relative permittivity εr (dimensionless) and Electrical conductivity σ (SI unit: S/m) take values From material. For User defined enter different values or expressions.

Enter a value or expression for the Layer thickness dl (SI unit: m). The default is 1 cm.
