Cool Calculate Heat Flux in a Patch

Hello community,

I simulated the flow inside a nozzle using the rhoCentralFoam solver and I want to calculate the heat flux along the nozzle wall. However, this is a special case as I replaced the "wall" with an inlet to reproduce something similar to a nozzle with sweat cooling.

The thing is the wallHeatFlux only gives me the heat fluxes in boundaries defined as "wall" and I do not have much experience modifying the code.

Anyone has an idea of how can I determine the heat flux along a patch?

Thank you in advance
