Verify the Application of Maxwell-Generated Losses

Ensure that the losses generated by Maxwell are the same as those consumed by the Mechanical. To verify the application of losses, check System Coupling's Transcript and EnSight-formatted Results files, as described in the following sections:

Review Losses in the Transcript

Review the Sum values for the final coupling iteration to verify that the losses sent by Maxwell match those received by Mechanical.

Visualize Loss Results in EnSight

In EnSight, visualize the application of Maxwell-generated losses to Mechanical's thermal analysis. Use the following variables:

  • Mechanical (nodes): Heat_Rate_Density__NS

  • Maxwell (elements): Loss_per_unit_volume__ES

For consistency, adjust the palette ranges as shown in the image below.
