Add the Heat Rate Density data transfer:

1. In the Outline pane under Coupling Interface, right-click Coupling Interface 1 and select Add Data Transfer.

   The Data Transfer branch is added to the tree, with Data Transfer 1 defined below it.

2. Right-click Data Transfer 1, select Rename, and change the name to Heat Rate Density

   The data transfer name is updated in the tree.

3. Click the Heat Rate Density data transfer.

   Corresponding settings are shown below in the Properties pane.

4. Set Target Side to Two.

   This specifies the side that will receive the data transfer quantity. In this case, Mechanical (side two) will receive losses generated by Maxwell (side one).

5. Keep the variable values, which are automatically populated as follows:

   • Source Variable is set to Loss.

     This is Maxwell's output variable.

   • Target Variable is set to Heat Rate Density.

     This is Mechanical's input variable.

Add the Temperature data transfer:

1. Right-click the Data Transfer branch and select Add.

   Data Transfer 2 is added to the tree below the Heat Rate Density data transfer.

2. Right-click Data Transfer 2, select Rename, and change the name to Temperature

   The data transfer name is updated in the tree.

3. Click the Temperature data transfer.

   Corresponding settings are shown below in the Properties pane.

4. Keep the variable settings, which are automatically populated as follows:

   • Target Side is set to One.

     This specifies the side that will receive the data transfer quantity. In this case, Maxwell (side one) will receive temperatures generated by Mechanical (side two).

   • Source Variable is set to Temperature.

     This is Maxwell's input variable.

   • Target Variable is set to Temperature.

     This is Mechanical's output variable.
