TAGGED: electric-potential, fluent, joule-heating, material-properties

I'm trying to solve the following issue.
I have an aluminum wire in a fluid domain.
I am applying 18 volts on one side of the wire. the electric resistance changes with temperature change according to this formula : 𝑅=𝑅01+𝛼(𝑇−𝑇0)R=R_0 (1+α(T-T_0)) where Temperature Coefficient: 0.002 1/K and Resistance at 20°C: 11.23 Ohm.
in Fluent material properties for aluminum I have to add electric conductivity, there is no option to add the resistance. How can I write the electric conductivity as an expression with a varying resistance with the formula above?
