thx.
well f(x,y) is an unknown as well as f_3D but maybe an iteration would work if one is not using a direct solver?
so maybe? any suggestions?
I think we're talking at cross purposes. As I understand it f and f_3D are both unknowns. However, f enters the f_3D equation through strongly enforced boundary conditions. Now, if f is somehow a function of f_3D, then this makes the equation for f_3D implicit in the boundary conditions. Since we have: equation_for(f_3D) == 0 in the bulk and f_3D = f on the boundary But f = f(f_3D)! So you need to figure out some way to break this implicitness I think. But maybe I misunderstand what is going on. Cheers, Lawrence
