Hi Phani, Jean-Paul is right that one could use a less strict assert. But that's won't help you with actually using ContinuousQuadratureDataTransfer to transfer the data. That's the main purpose of CellDataStorage -- provide association functionality between cells and collection of data objects per cell. There are code snippets that explain this in https://www.dealii.org/developer/doxygen/deal.II/classparallel_1_1distributed_1_1ContinuousQuadratureDataTransfer.html That's why we never really considered/test a template parameter DataType to represent C++ scalar.
