THERMAL ANALYSİS IN SOLIDWORKS

I am new to the simulation part of solidworks thermal analysis and am having trouble. I have tried to find a tutorial on how do to what I need but my case is so over simplified that all of the help is more advanced than my problem. The problem is:
Mounted flares resiztans connected to copper plate.
‘I want to find the heat conduction to the steel which is connected with the heat transfer of resizantan.
picture is ext.
I was confused about the heat transfer coefficient.
what will be the unit
W / M2.K OR W / M.K.

FOR STEEL(1,2312) 40 W/m.k PUT İN solidworks
