Hi @arshiah
You have selected an External circuit for excitation, have you defined one?
If you have defined the external circuit the popup window will look like below screenshot

You can define an external circuit as explained below, make sure you have the same name for the inductors in the circuit as given in the excitation.
Right-click on excitation>external circuit> edit external circuit.
Select create a circuit on the pop window.
Create your external circuit and export the netlist.
Come back to maxwell design Right-click on excitation>external circuit>edit external circuit.
Select import circuit netlist on the popup window and you are done.
Refer Mawell help for additional information on the external circuit.
You can also create a Maxwell model from an inbuilt RMXprt motor example that creates an external circuit for reference.
Regards Navya
