Hi all, I have just started in dealii and going through the tutorials to solve a Neumann boundary value problem.
I have the following situation: the Neumann boundary data (say g) is defined as a Function and the solution obtained by solving my pde is a Vector<double> (say v). How do I take the L2 inner product of g and trace(v). How do I get this inner product between a Function and a Vector <double>. I can find each face which is on the boundary and I can get the values of g at all the quadrature points of the face and the JxW at those points. However, to obtain the surface intergral, I also need the values of v at these quadrature points. How can I get the values at the quadrature points of the solution v?
