Modeling electrical conductivity as a function of electrical resistance

      Hi every body :

      Hoping that everything is going well.

      i need urgent help please.

      -the electrical conductivity in my problem is not constant, it changes with electric resistance, and this electric resistance changes with temperature.

      the electric resistance in my problem is given by 𝑅=𝑅_0 (1+𝛼(π‘‡βˆ’π‘‡_0)) where T_0 is 20C and T is static temperature of the wire. and R_0 is 11Ohm.

      how can I write an expression to incorporate this resistance into the conductivity for aluminum in fluent. thanks

      Hi, Under Electrical Conductivity options, you can select Expression and then input the expression as required.
