Claire,
this looks to be the problem:
/home/claire/Logiciels/deal.II/deal.II-v8.4.1/include/deal.II/base/work_stream.h:1230:3:
note: template argument deduction/substitution failed:
/home/claire/Logiciels/deal.II/deal.II-v8.4.1/Doctorat/slm_v18/slm_v18.cc:1031:17:
note: deduced conflicting types for parameter ‘const Iterator’
(‘dealii::TriaActiveIterator<dealii::DoFCellAccessor<dealii::hp::DoFHandler<3,
3>, false> >’ and ‘dealii::hp::DoFHandler<3, 3>::cell_iterator {aka
dealii::TriaIterator<dealii::DoFCellAccessor<dealii::hp::DoFHandler<3, 3>,
false> >}’)
WorkStream::run(dof_handler.begin_active()
can you try something like:
typename hp::DoFHandler<dim>::active_cell_iterator cell =
dof_handler.begin_active(), end_cell = dof_handler.end();
WorkStream::run(cell, end_cell, ...)
This should help your compiler deducing the templated parameters.
Best,
Bruno
