I'd like to simulate the heating in a small thin wire copper coil in 2D. When current is going through the wire it heats up. This changes the resistance which increase the heat loss further. In the end I'd like to simulate a 3D assembly(coil+magnets etc.).
Each wire is modeled as a heat source. The power it produces depends on the current and the resistance of that wire at a certain Temperature. How do couple this effect?
I can't find the temperature of the wire as an input to the heat source calculation. I have defined global parameters for wire dimension and current. Im trying to define global variables for resistance and heat source power. But I can't find the temperature.
There is an old demo for fuse heating but this method does not work since I can't find materials with temperature dependent variables as input. This would be a great option though.
