Hi, I just started to use GetFEM++ few days ago. My project is to predict potential distribution when amount of constant current injected in 3D structure. Thus, my FEM model is laplace equation. However, in GetFEM++, I could not find how to set neumann boundary condition. In detail, I want to set neumann boundary condition at some face (grad(x)*n=k, x is solution, n is normal vector of face, and k is constant) Could you give me some advice or any clue?.
Thank you
