Hi! Your data lives on quadrature points, correct? And I assume you are using the parallel::distributed::Triangulation since you are checking for locally owned cells.
We have a class parallel::distributed:: <https://www.dealii.org/developer/doxygen/deal.II/classparallel_1_1distributed_1_1ContinuousQuadratureDataTransfer.html> ContinuousQuadratureDataTransfer <https://www.dealii.org/developer/doxygen/deal.II/classparallel_1_1distributed_1_1ContinuousQuadratureDataTransfer.html> that could fit your purpose. You can find some example applications in our tests, for example tests/base/quadrature_point_data.cc <https://github.com/dealii/dealii/blob/master/tests/base/quadrature_point_data.cc> . Hope this helps!
