Hi all, I hope you doing well!
i am trying to simulate the motion of ionic species under electric field. I am using a set of equations such as Poisson equation, drift, and difussion equation (where the coefficient of difussion is related to the electrical mobility through the Eistein relationship), and mass balance equation for continuity. My code seems fine and it give me a reasonble results for the first time step. However, nothing change after that and i get the same results for each time step. The ionic species are supposed to move with the electric field and the concentration profile will change. That new concentration profile will be used to calculate the new potential, new electric field, and new charge density. But, anything i do seems to work to be able to see those changes.Hi all, I hope you doing well!
