Hi Kyusik, If you mean that you want to extract the solution at the quadrature points then this certainly is possible. You can do with functions like those in FEValues::get_function_values <https://www.dealii.org/developer/doxygen/deal.II/classFEValuesBase.html#a3f84ee49f0fbb32bfe01b2f4a473bb47> and FE_Values::get_function_gradients <https://www.dealii.org/developer/doxygen/deal.II/classFEValuesBase.html#a69c63f8be0311c8970253276ac7df138> etc. Their use described in some of the later tutorials, for example step-9 <https://www.dealii.org/developer/doxygen/deal.II/step_9.html> and step-15 <https://www.dealii.org/developer/doxygen/deal.II/step_15.html#MinimalSurfaceProblemassemble_system> (scalar-valued problems), step-42 <https://www.dealii.org/developer/doxygen/deal.II/step_42.html#PlasticityContactProblemassemble_newton_system> (vector-valued problem) and step-44 <https://www.dealii.org/developer/doxygen/deal.II/step_44.html#Solidupdate_qph_incremental> (multi-field problem).
