Yes the FEValues defined for each dell dinfo1.cell and dinfo2.cell provides all the interior information of the cells( however I did not succeed in the accuracy test so far, but it works ).
In fact, apart from the interface values I need solution values at the interior of each cell, usually for time dependent problem this is not really needed ( only the limit value at the face is required from each side of the face). In my case the method is a bit different, here to compute the interface flux it needs to know few values of the solution in the interior as well.( I am not sure if it is an efficient way to compute it in the call integrate_face_term in the meshworker set up).
