When the predefined Thermoelectric Effect interface (
) is added (found under the
Heat Transfer branch (
) of the
Model Wizard or
Add Physics windows), it combines the Electric Currents and the Heat Transfer in Solids interfaces for modeling Peltier-Seebeck-Thomson effects in domains and on boundaries. In addition, the
Electromagnetic Heating and the
Thermoelectric Effect multiphysics couplings are added automatically.
As a predefined multiphysics coupling, the Electric Currents and
Heat Transfer in Solids interfaces are added to the Model Builder. In addition, a
Multiphysics node is added, which includes the
Thermoelectric Effect and
Electromagnetic Heating multiphysics coupling features. Additional features describing the thermal and electrical effects on boundaries need to be active in each interface to account for the effect also on boundaries.
The Heat Transfer in Solids interface provides features for modeling heat transfer by conduction, convection, and radiation. A Solid model is active by default on all domains. All functionality for including other domain types, like a fluid domain, is also available. The temperature equation defined in solid domains corresponds to the differential form of the Fourier’s law that may contain additional contributions like heat sources. The thermoelectric effect in domains is added through a contribution to the conductive flux. A
Thin Layer feature may be added to account for the thermoelectric effect also on boundaries.
The Thermoelectric Effect multiphysics coupling is also available when there is any version of the Heat Transfer or Heat Transfer in Shells interface and one of the compatible AC/DC interface:
