thermoelectric generator coupled with circuit module

Hello,
I am trying to simulate the connection between a thermoelectric generator module and a load in COMSOL to observe how changes in the load affect voltage and current output. However, when I integrate the circuit module with the thermoelectric module, the steady-state solver fails to converge to a solution.
For boundary conditions, I have set a constant temperature at the cold end, and I have tried both constant temperature and constant heat flux conditions for the hot end, but the issue persists.
Could you provide any suggestions or insights on how to resolve this problem or improve the model setup?
I am currently facing an issue with my MPH file being too large to upload. If possible, you could provide an email address so that I can send the file for your review.
Thank you in advance for your guidance.

If you follow the instructions for reducing file size found in the link below it is highly likely that the resulting file will be small enough to post.

Thank you, sir. After following your instructions, I have managed to reduce the size of my MPH file to its minimum. However, it is still around 10 MB, not able to upload.

In any case, I can't help personally because I don't have the semiconductor module.
Posts here that do not include the .mph file almost never get a response. Even .zip files are avoided.
If your model is still too big the only reason I can think of is an extremely complex geometry. It may be useful to construct a model problem with the same physics and a much simpler geometry. (When you do this you may even find the issue).

I have resolved this issue by enabling the fully coupled option in the stationary solver. In any case. thank you very much for your assistance.

The fully coupled option in the solver is the right method to solve this question.
