Hello,

I'm working on Thermoelectric Generator and I would like to have a basic model with the equations used in COMSOL, Could anyone who worked in this field, please help.


With Regards .

Hello,

I have. I went ahead and built a Thermoelectric node but I am still having difficulties. One error I noticed was that you may not have a a temperature and electric potential boundary on the same surface. I was wondering if there is anything already built to compare?

Thanks in Advanced,

Gaston Piller

I actually was able to solve the issue on the boundary conditions--it ws due to a boundary override rule.

I did however, notice that if you reverse the conditions, ie, state temperature boundary conditions, and allow for COMSOL to provide a Voltage value, the results do not match.
