Addition of heat transfer from tabs via conduction in the pouch cell 2D current collectors thermal model

[abhishek-appana]

Hello everyone,

I am working on modifying the thermal "x-lumped" pouch cell model in PyBaMM. Mainly, I want to add heat transfer via conduction from the tabs.

In the thermal submodel, the edge cooling is considered uniform along the boundary. Code

How can I modify this part to include conduction heat transfer in the boundary section where tabs are present?

I see that modifying the boundary conditions is straightforward. But I was not able to understand how to modify the PDE.

Thanks for the help in advance!
