Hello, I'm not really good with DC, but I have to solve one problem connected to it very closly.
I have a model of a bimetallic Copper-Aluminium conductor. I know, that the value of generated current density in my conductor can achieve 100[A/cm^2].
I can't understand what type of boundary conditions should I use in electric currents interface to make my conductor a part of an electric chain. Here is the chain: aluminium is connected to the transmission line, and copper is connected to an electrode of steel (such conductors are used during electrolysis of Al to connect transmission line aluminium cables with electrodes of steel). So what boundary condition should I use instead of transmission line "Normal current density" or "Terminal" or some other..., and what instead of electrode "Ground" or "Terminal" and choose circuit?
