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.
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.
