For more information about the Terminal condition, see Terminal in the documentation for the Electrostatics interface.

For 3D components, enter the Edge radius (SI unit: m) for the virtual tube surrounding the edge. The default value is 0.1 m. It is generally assumed that the edge radius is small in comparison to other geometrical measures of the model, such as the edge length and the distances between different edges in the geometry.

To correctly calculate the terminal charge and the corresponding capacitances, if voltage Terminal is used on boundaries between The Electrostatics Interface and The Electrostatics, Boundary Elements Interface, let the dependent variable for The Electrostatics, Boundary Elements Interface be the same as the dependent variable for The Electrostatics Interface and disable Electric Scalar–Scalar Potential Coupling. How to set the name for the dependent variable is described in the Dependent Variables section. Since the Electric Scalar–Scalar Potential Coupling is disabled, add manually a Fully Coupled node to the Stationary Solver below the Solution node in the Solver Configurations.
