Update: I switched to my old trick of nodal averaging method: take the average of the values at quadrature points, then add this average to the vertex dofs. And if a vertex is shared by n cells, divide the values at the related dofs by n. I am happy with the results because they look quite smooth.
The only concern is that: for a stress component, say Sxx, appears in my resulting vtu files as Sxx_0, Sxx_1 (in 2D) because the variable Sxx is a vector of size n_dofs as required by the add_data_vector function. Is there a way to get rid of the unnecessary duplicates? Essentially I want Sxx to be a vector of size n_vertices.
