The Electromagnetic Heating node represents the electromagnetic losses,
Qe (SIĀ unit: W/m
3), as a heat source in the heat transfer part of the model. It is given by
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
emh.
When nodes are added from the context menu, you can select Manual (the default) from the
Selection list to choose specific domains to define the electromagnetic heat source or select
All domains as needed.
When Electromagnetic Heating is added as an effect of adding a
Microwave Heating interface, the selection is the same as for the participating interfaces.
When nodes are added from the context menu, you can select Manual (the default) from the
Selection list to choose specific boundaries to define the electromagnetic boundary heat source or select
All boundaries as needed.
When Electromagnetic Heating is added as an effect of adding a
Microwave Heating interface, the selection is the same as the exterior and interior boundaries of the
Domain Selection of the participating physics interfaces.
This section defines the physics involved in the Electromagnetic Heating multiphysics coupling. By default, the applicable physics interface is selected in the
Electromagnetic list to apply the
Heat transfer to its physics interface to establish the coupling.
You can also select None from either list to uncouple the
Electromagnetic Heating node from a physics interface. If the physics interface is removed from the
Model Builder, for example
Heat Transfer in Solids is deleted, then the
Heat transfer list defaults to
None as there is nothing to couple to.
