Need help understanding the correlation for heat generation between the 1D and 3D models in batteries

I am new to COMSOL and have been going through some of the tutorials for batteries. I completed the tutorial 'Thermal Modeling of a Cylindrical Lithium-ion Battery in 3D' and have a question about one of the steps.
At one point in the tutorial it has you put in a variable for heat generation (Qh). The expression for Qh is :
Looking at this expression it looks like it is using Qh from the 1D model for the 3D model. I've looked through the 1D model and can't find a value for Qh anywhere. Can someone explain the correlation or how COMSOL is using the 1D model to get the heat generation in the 3D model?
Thank you for your help,
