Dr. Bangerth, Thank you for the kind explanation.
Now, I understand what is wrong... I'm really sorry but, could I have one more question....? > > The approach you use, making things look like an assembly step, is not > appropriate for what you want to do.

I would like to solve free boundary problem. So, the boundary condition would be calculated from sources(current in coils) and line integral of green function and so on.... Especially, the calculation of boundary values includes the line integral, that is why I want to use an assembly step. So, do you think it is hard to apply boundary condition without using VectorTools::interpolate_boundary_values...? Thank you.
