Default UDF to calculate average heat flux

dynamics is on a distinguished road
I am running a steady axisymmetric simulation (turbomachinery flow). During steady simulations, the wall heat flux oscillated due to unsteady and 3D nature of the flow (and I am forcing to solve it using steady axisymmetric approach).

I want to cumulatively average the wall heat flux w.r.t iterations ie.,
Let q_i = heat flux on a wall face at 'i' th iteration




and so on

After the computations, I am planning to output the average heat flux (qav) on all the walls using
file/write-profile [wall_name]

Which UDF I need to use and please give some leads so that I can write it myself.

Thanks in advance
