Default modeling elecric potential with additonal variable

Hi, everyone I want to model electric potential, electric current and corresponding ohmic heat across the porosity and solid domains with cfx 11.0. Since the porosity domain doesn't support the electromagnetic model now which is BETA feature.

So I want to use additional variable method to deal with this problem. But when I check the help document for poisson equation, I found fluid density and kinetic diffusivity in the poisson equation. The question rises up: for electric potential what is the corresponding density and kinetic diffusivity and how can I set the electric conductivity?

Any reply will be appreciated. Regards. frank
