Hi,
My project is 'Modeling the electrosorption'.I tried to model adsorption of ions(Na+,Cl-) on electrodes due to applied electric field.I model using Poisson Nernst Planck equation which is made up of three parts convection ,migartion-diffusion of ions and this equation is coupled with single phase laminar flow (Navier Stokes equation).I used Coefficient Form PDE for writing this PNP equation and General Form PDE for calculating surface concentration of adsorbed ions on the electrodes. Study type is stationary for laminar flow and Time dependent for electrostatics,coefficient Form PDE and General Form PDE.So my problem is every time i compute only one error "out of memory during LU factorization".I also attached my file(in version 4.3) and could any one pls help from this.
Thanking you
