I'm studying a problem in which I need to store quantities (symmetric tensors
and doubles) at quadrature points, and I do that by using a PointHistory class
as done in step 44
(https://www.dealii.org/current/doxygen/deal.II/step_44.html#Quadraturepointhistory).
The only difference is that I'm defining the CellDataStorage as
CellDataStorage<typename
parallel::distributed::Triangulation<dim>::cell_iterator,
PointHistory<dim> > quadrature_point_history;
because I use a parallel distributed triangulation.
I don't have a particularly good solution in my head, but if you look at how
programs such as ASPECT do checkpoint/restart, then they use a mechanism such
as p::d::SolutionTransfer to attach data to the triangulation, save/restore,
and unattach. You might be able to achieve the same effect by using the
CellDataTransfer class, though I have no idea if anyone has ever tried that.
