In comsol, we've already input Electric Currents module,Heat Transfer in Solids module and Multiphysics module with electromagnetic heating. But in metal parameter, we can input the function to let thermal conductivity and electrical conductivity with temperature dependent. How to do to consider Wiedemann-Franz law (relationship between electrical conductivity and thermal conductivity). Thanks

Hello,
Have you tried typing the electric conductivity explicitly (i.e. as a function of T only), and typing an expression for the thermal conductivity that depends on the electric conductivity and on T according to the Wiedeman-Franz law? (or vice versa: you could type an explicit expression of T for the thermal conductivity and an expression for the electric conductivity that depends on the thermal conductivity and T).
Best,
Jeff
