The Layered Piezoelectric Effect multiphysics node () passes the appropriate relative permittivity from the Piezoelectric Material node in the Layered Shell interface (where it is specified together with the other material properties of the piezoelectric) to the Piezoelectric Layer node in the Electric Currents in Layered Shells interface. The Piezoelectric Layer node implements the equations for the charge balance in shells, and it does not require any user settings when the interface is coupled through the multiphysics coupling node.

The Label is the multiphysics coupling feature name. The default Label (for the first multiphysics coupling feature in the model) is Layered Piezoelectric Effect 1.

The Name is used primarily as a scope prefix for variables defined by the coupling node. Refer to such variables in expressions using the pattern <name>.<variable_name>. In order to distinguish between variables belonging to different coupling nodes or physics interfaces, the name string must be unique. Only letters, numbers, and underscores (_) are permitted in the Name field. The first character must be a letter.

The default Name (for the first multiphysics coupling feature in the model) is pzel1.

The boundary selection is locked so that all applicable boundaries are selected. Only boundaries that have both Piezoelectric Layer selected in the Electric Currents in Layered Shells interface and Piezoelectric Material selected in the Layered Shell interface are selected.

This section defines the physics involved in the Layered Piezoelectric Effect multiphysics coupling. The Layered shell and Electric Currents in Layered Shells lists include all applicable physics interfaces.

You can also select None from either list to uncouple the Layered Piezoelectric Effect node from a physics interface. If the physics interface is removed from the Model Builder, for example Layered Shell is deleted, then the list defaults to None as there is nothing to couple to.
