My question is, is there a way to involve two different dof_handlers when
using the WorkStream class, something like the following:
What you are looking for is an object that looks like a *pair* of iterators
and when you call ++it on it, then it increments both elements of the pair.
The class SynchronousIterator does exactly this.
Alternatively, it is possible to convert an iterator into one DoFHandler to an
iterator into another DoFHandler, like in
typename DoFHandler::active_cell_iterator cell_stokes
= stokes_dof_handler.begin_active();
for (..., ++cell_stokes)
{
typename DoFHandler::active_cell_iterator
cell_T (cell_stokes->get_triangulation(),
cell_stokes->level(),
cell_stokes->index(),
&temperature_dof_handler);
...do something with both iterators...
}
Best
