[Help] AC electroosmosis, defining the electrode-electrolyte boundary condition
Dear all, I am working on a 2D AC electroosmosis problem, the model consists of a pair of electrodes. The models which I adopt are (1) Conductive DC media, and (2) Incompressible Navier-Stoke. I have...

Dear Tom, Thanks for your reference :) I tried to write the boundary conditions according to the paper that i mentioned (Loucaides et al. 2007). My solution does not converge, and the unconverged...

Hi, I followed the paper in the past as well, but what I used was the model of "electrostatic" or "PDE coeff form" directly. I did not try to use"conductive media DC" to solve this problem before. I m...

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...

From what I am aware of, no. If you want to have a PDE on a boundary you have to use the Weak form.
