heat transfer across the heated wall

I am modelling phase change material inside a square enclosure, the PCM starts melting ,with time it will be transformed from solid to liquid, the natural convection in the molten PCM is taken into account.
1)I want to know how to find the convective heat flux across the heated wall, which one should I use of all the domain fluxes and boundary fluxes. which one can give the correct heat flux due to convection and due to convection across the heated wall??
2)I want to divide the wall at different heights and find the heat flux across each height, is it possible?
for example, if my wall is of height H=0.1m,
I want to find the evaluation function of time of the heat flux across each height dividing my wall into 5 zones.
for example Q1 across the height going from y=0 to y=0.02
Q2 across the height going from y=0.02 to y=0.04
Q3 across the height going from y=0.04 to y=0.06
Q4 across the height going from y=0.06 to y=0.08
Q5 across the height going from y=0.08 to y=0.1
Thank you in advance.
