In the Transport of Diluted Species, how to handle with the neutrality problem?
When I only used the Transport of Diluted Species module, H ion and Cl ion had the different concentration within the domain, since I only added flux boundary condition of H ion.
Then I tried to couple this module with Poisson Equation. I used Electric Currents to govern Poisson Equation. But the result was not reasonable. In theory, the concentration of H and Cl should be different, but maybe it's the neutrality that made the H and Cl had the exactly same distribution in the domain. The Neutrality condition should be satisfied globally, but it seemed that it was satisfied locally. I'm a new bird of COMSOL, and I have no idea how to fix this problem. I hope somebody can help me.
Many thanks in advance.
