The Piezoresistivity, Shell multiphysics coupling node () computes the appropriate conductivity tensor according to the mechanical stress or strain from the Linear Elastic Material node in the Shell interface and the piezoresistivity properties from the Piezoresistive Shell node in the Electric Currents in Shells interface.

The Label is the default multiphysics coupling feature name.

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 pzrs1.

Only boundaries that have both Piezoresistive Shell selected in the Electric Currents in Shells interface and Linear Elastic Material selected in the Shell interface are applicable.

This section defines the physics involved in the Piezoresistivity, Shell multiphysics coupling. The Shell and Electric currents, shell lists include all applicable physics interfaces.

The default values depend on how the Piezoresistivity, Shell coupling node is created.

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