Verify that all bodies to receive temperature data from Fluent are made temperature-dependent materials. The energy model must be on. For this tutorial, you are interested only in the material properties of the magnets.
Important: When using the same material(s) in multiple participants, take care to ensure that common properties (for example, conductivity) are consistently defined. This consideration is often relevant in analyses involving thermal data transfers.
In the Project Manager, expand ElectricMotor / Definitions / Materials.
Double-click N5211.
The View / Edit Material dialog opens.
On the right side of the dialog, verify that the Thermal Modifier check box is selected.
In the Properties of the Material table, verify that for the Magnitude of the material's magnetic coercivity, the Thermal Modifier is set to the following expression:
1.0-0.00647425*(Temp-20) Specifying a thermal modifier for the material ensures that the material is temperature dependent.
Click to close the dialog.
This is the site of the two-way coupling, where Maxwell generates losses and sends them to Fluent for a thermal simulation. This is also where Maxwell receives the temperatures generated by Fluent and adjusts material properties and electromagnetic fields solutions accordingly.
Because thermal solutions are being solved on both sides of the coupling interface, material thermal properties must be consistently defined by both participants. Later, when you do the thermal setup, you can verify that the Fluent and Maxwell models are made of the same material and have compatible temperature-dependent properties.
