This is an interesting question. Yes, if you have a set temperature on one side, a negative heat power sucking out power on the other side, and different conductivity wires between I might expect that the temperature values would be different. I made a mock model and did this and the values despite being nonsensical (negative Kelvin values) did change. The temperature coloration did remain the same because the extents of the legend changed to accommodate the different temperature values but the difference is there. There is a large pooling of heat on the temperature side and a large "vacuum" of heat on the other side.

Hi Ryan, thanks for your response.
As I suspected, thermal conductivity influences steady-state temperature. Your simulation made me try again, and I found out that if I make two identical assemblies from scratch, changing only the material of the connector, then the steady-state temperature does indeed change.
Before what I was doing was right clicking on the material, clicking "Edit Material" and manually changing the thermal conductivity. Evidently this doesn't work. Do you know the right way to change a part's thermal conductivity?
That should work though. Did you copy/paste the material to your custom folders before editing?
As you are going through "Edit Material" are you making edits then both pressing 'Save' and 'Apply'? I might expect the previous properties to be retained in the Simulation model if you are not doing both.
If I edit the material in the assembly file, then the results of the thermal study are unaffected, but if I edit the material in the part file, then the results are affected.
Further, the edits during the assembly have an effect, since the saved values appear during the edit of the part file.
Does anybody have any idea how this is going on? I'm finding the right thermal conductivity through trial and error, and it would be nice if I didn't have to click back and forth between all these files.
