Hi all,
Once again perplexed by the c++ compiler. I am getting the following error
when trying to compile a program from the code gallery.
prog1.cc:In instantiation of ‘typename dealii::DataOut<dim,
DoFHandlerType>::cell_iterator Prog1::FilteredDataOut<dim,
DH>::first_cell() [with int dim = 3; DH = dealii::DoFHandler<3, 3>;
typename dealii::DataOut<dim, DoFHandlerType>::cell_iterator =
dealii::TriaIterator<dealii::CellAccessor<3, 3> >]’:
prog1.cc:2668:5: required from here
prog1.cc:2670:54: error: no type named ‘active_cell_iterator’ in ‘class
dealii::DataOut<3, dealii::DoFHandler<3, 3> >’
typename DataOut<dim, DH>::active_cell_iterator cell =
this->dofs->begin_active();
^~~~
prog1.cc:2670:54: error: no type named ‘active_cell_iterator’ in ‘class

dealii::DoFHandler<3, 3>; typename dealii::DataOut<dim,
DoFHandlerType>::cell_iterator =
dealii::TriaIterator<dealii::CellAccessor<3, 3> >]’:

(predicate,old_cell));
Looking in the manual I see the following which makes me think the code
should work
using DataOut
<https://www.dealii.org/current/doxygen/deal.II/classDataOut.html>< dim,
DoFHandlerType >::cell_iterator
<https://www.dealii.org/current/doxygen/deal.II/classDataOut.html#a501c6b6a2ac9210e9f5742898908183c>
= typename DataOut_DoFData
<https://www.dealii.org/current/doxygen/deal.II/classDataOut__DoFData.html><DoFHandlerType,
DoFHandlerType::dimension, DoFHandlerType::space_dimension>::cell_iterator
<https://www.dealii.org/current/doxygen/deal.II/classDataOut.html#a501c6b6a2ac9210e9f5742898908183c>
Should I just change active_cell_iterator to cell_iterator? I am worried
that they wont work the same creating problems downstream.
Thanks in advance.
