Hamed, It's difficult to judge these kinds of problems just looking at the graphical output after solving. I would suggest you to look at the constraints in the ConstraintMatrix using ConstraintMatrix::print[1] for a mesh consisting of has few cells as possible. Using DoFTools::map_dofs_to_support_points[2] you can then verify that these are correct.
