heat transfer in a HVDC poewer cable

I have some questions regarding temperature Distribution in HV cable.
I am trying to observe heat Transfer in a cable, I am considering a very simple model , Inner core is a conductor and outer is ground conductor and between is the insulated gas. First, I have coupled EC and HT modules in comsol. I made a 2D model for the cable . I have the constant current value in the core conductor. So what tpye of current source should i select from EC module. Boundry current souce or a normal current source or any other?
Secondly, i am considering the Joule heating effect of the current in the Center conductor So what type of heat source should I select from HT module? When I select A heat source then from General heat source I choose total power Dissipation density the the temperature does not changes.
Can anyone guide me where I am wrong
