The Pyroelectricity interface (
) combines Electrostatics and Heat Transfer in Solids interfaces together with the constitutive relationships required to model pyroelectricity. Both the direct pyroelectric and inverse electrocaloric effects can be modeled. This interface requires the MEMS Module license.
The Piezoelectricity interface is available for 3D, planar 2D, and axisymmetric 2D geometries.
When this multiphysics interface is added using the Model Wizard, an
Electrostatics interface and a
Heat Transfer in Solids interface are added to the
Model Builder.
In addition, the Multiphysics Couplings node is added, which automatically includes a multiphysics coupling node
Pyroelectricity.
The full functionality of the Electrostatics interfaces is accessible at the domain, boundary line, or point level in the geometry. The participating Electrostatics interface by default adds the
Charge Conservation node with its selection set to all domains, and the material type set to
Solid. This node serves to represent solid dielectric material domains. Any number of
Charge Conservation nodes can be also added manually to the interface and configured to represent either solid or nonsolid (for example, air or free space) materials.
The Heat Transfer in Solids will use its default domain feature,
Solid, where you enter the thermal properties of the material. All heat transfer functionality for modeling is also accessible to include surrounding solid or nonsolid domains. To model heat transfer by convection in nonsolid domains, you can add a
Fluid domain feature.
