Hello!
I am doing simulation of saturated by water sand rock (porosity 0.35). No flow of water, but on the side borders I am applying eleсtric potential difference. Electrical current pathing through water accumulate temperature raising in the rock.
However I can not combine two modules: Electrical current and Heat transfer in Porous media. Comsol requires heat transfer parameters for rock and water, but electrical parameters - only for rock, without water. It can not do both.
How to solve this problem? Am I using wrong modules?
Thank you!
