Re: [Help] AC electroosmosis, defining the electrode-electrolyte boundary condition

If a boundary condition contains a pde you have to use weak form to get correct results, i.e. you have to solve the Laplace equation with the continuity PDE relating the derivative of the potential on the edge of the double layer using the weak form mode. Therefore, you can not solve this problem using the conductive dc media mode.
The Comsol Modeling guide has a chapter , page 345 in my version, on how to convert to weak form.
