Thermal expansion and joule heating

Hello,
I am trying to model the thermal expansion and joule heating physics in a complex model in Comsol. At the moment I am using just a simple cable, where I want to apply a current source of 900A for a period of time and check the results. I attach the model.
I don't have any information regarding the voltage, so I just assumed a 30 kV source, but I am not sure if it is needed at all.
Also it seems, I have some problems, when using the electrical power dissipation as a heat source.
Please can you check it and advice?
For any question, please let me know.
Kind regards,
Pavlos.
