power extraction from PN junction using Electric Circuit interface

Hello everyone,
I’m currently working on a project in COMSOL where I simulate multiple PN junctions connected in a serpentine layout. I apply a thermal gradient (Seebeck effect) and successfully generate a voltage (~70 mV), but I’m struggling to calculate the extracted power.
I’ve tried adding the Electrical Circuit interface and connected a resistive load, but COMSOL won’t compile. I suspect that the circuit isn’t properly linked to the 3D physics, or I may be missing a terminal or an external connection setup.
Has anyone worked on a similar model or could point me to a tutorial/example showing how to connect a terminal from a thermo-electric model to an external circuit and extract power?
Any help or guidance would be greatly appreciated.
Thank you!
