Create Maxwell's System Coupling Setup

To enable the exchange of data between the electromagnetic and thermal analyses, create a System Coupling Setup. This creates an interface between regions on the two models, allowing the solid part of the electromagnetic model to receive temperature from the thermal model during the execution of the co-simulation. When you exit the setup dialog, Maxwell generates the configuration files it needs to work with System Coupling.

  1. In the Project Manager, expand Maxwell3DDesign.

  2. Right-click Optimetrics and select Add > System Coupling Setup.

    The System Coupling Setup dialog opens.

  3. Under Context, verify the following settings:

    • Setup is set to Setup1.

    • Frequency is set to 1000Hz.

  4. Under Quantity, note the quantities included in the coupling setup:

    • Temperature is defined as an input (regions for temperature inputs correspond to bodies with temperature-dependent properties).

    • Volume Loss is defined as an output (regions for loss output correspond to all bodies on which any losses are generated).

  5. Verify the object temperature:

    1. In the Settings column, click the Object temperature button.

      The Temperature of Objects dialog opens.

    2. Verify that Include Temperature Dependence and Enable Feedback are both selected.

    3. Verify that the core and the coils are set to temperatures of 500 K and 600 K, respectively.

      Note:  This value for the core temperature takes into account the expectation that inductive heating will cause the initial temperature for the thermal analysis (300 K) to rise by several hundred degrees. An electromagnetic temperature of 600 K will drive Maxwell's adaptive passes and mesh generation.

    4. Click Cancel to close the Temperature of Objects dialog.

  6. Click OK to save the setup and close the System Coupling Setup dialog.

    When you exit the dialog, Maxwell generates the configuration files it needs to participate in the co-simulation.

    Note:  If the configuration files are not generated automatically, In the Project Manager, under Optimetrics, right-click your System Coupling Setup and select Generate Configuration Files.

  7. Select File > Save and then File > Exit.

    Electronics Desktop closes.
