The Piezoresistive Effect, Boundary Currents multiphysics coupling node (
) computes the appropriate conductivity tensor according to the mechanical stress or strain from the
Linear Elastic Material node in the
Solid Mechanics interface and the piezoresistivity properties from the
Piezoresistive Material node in the
Electric Currents, Shell interface. The computed conductivity tensor is passed to the
Current Conservation node in the
Electric Currents, Shell 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
pzrb1.
Only boundaries that have both Piezoresistive Material selected in the
Electric Currents, Shell interface and are adjacent to domains with
Linear Elastic Material selected in the
Solid Mechanics interface are applicable.
This section defines the physics involved in the Piezoresistive Effect, Boundary Currents multiphysics coupling. The
Solid mechanics and
Electric currents, shell lists include all applicable physics interfaces.
You can also select None from either list to uncouple the
Piezoresistive Effect, Boundary Currents node from a physics interface. If the physics interface is removed from the
Model Builder, for example if
Solid Mechanics is deleted, then the list defaults to
None as there is nothing to couple to.
