electrical analysis ansys

[danielec1]

Hi, I'm a mechanical engineer not very expert on ansys v12.
I am trying to simulate a thermoelectric generator and I wanted to know how I can apply a thermoelectric resistance between 2 surfaces.
the surfaces are those highlighted in figure.. .
How do I also define the element used?
because I read that for 3d thermoelectric analysis can only be used:
Planner
solid 26
solids

Thank you in advance.. .

I did not specify that I initially did a thermal electric analysis and now I would like to check out current...how do I however apply electrical resistance?
Can someone give me some advice?
