Dear Wolfgang,
Thank you so much for your guidance. Step-35 is the example where
"SynchronousIterators" is used.

using IteratorTuple =
std::tuple::active_cell_iterator,
typename DoFHandler::active_cell_iterator>;
using IteratorPair = SynchronousIterators;

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
Dear Wolfgang,
Thank you so much for your inputs. Indeed, Step-31 is a good example for
what I am looking for. However, I have a follow-up question regarding using
the *WorkStream* class based on TBB during the assembly stage when two
different dof_handlers are involved.
To be specific, in

Dear all,
This is a similar question related to a post two years ago:

I am developing a fractional time stepping algorithm based on an operator
split. Basically, I can obtain the following monolithc system after the
finite element
