Malhar, the template arguments for DataOut are dim and DoFHandlerType where DoFHandlerType defaults to DoFHandler<dim> since you are using a DoFHandler<2, 3> object you need to specify the second template argument explicitly, i.e.
DataOut<2, DoFHandler<2,3>> data_out; You could have a look at step-38. Best, Daniel Am Di., 22.
