Homogenized multiturn coil Joule heating

I am a relatively new COMSOL user. I have a design using the magnetic fields module, with coils driven by electrical circuits in time dependent simulation. I'm using the magnetic fields module, and heat transfer in solids module, in a 2-d axisymmetric model.
The Joule heating of coils modeled as "single conductor" seems reasonable but I see no joule heating of the same coil when I model it as "homogenized multiturn". With the same design just changing from single turn (works) to a homogenized multi-turn, number of turns =1 no longer shows heating.
Note that the heating for multi-turn seems to be exactly 0, even with conditions that should create large temperature rises.
Is Joule heating supported for homogenized multi-turn? If so is some other setting required.
