At first, the reason why I would like to make vector G by myself (without
using VectorTools::interpolate_boundary_values) is that I would like to input
calculated values (not just function of position) on the boundary.
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...?
No. But I would advise to take a look at the implementation of that function
(in include/deal.II/numerics/vector_tools.template.h IIRC).
