Kyusik, As Wolfgang already mentioned, you want to use FEValues::get_function_values() to extract from a global FE Vector the local values at the quadrature points in the cell you are on. These quadrature points normally don't coincide with with the mapped unit support points of the FiniteElement you are using. Nevertheless, the global DoF indices of the local DoFs can be obtrained as usual by cell->get_dof_indices()
Have a look at some of the time-dependen steps, e.g. step-35::assemble_one_cell_of_advection, or just search for get_function_values in the examples folder.
