I would like to use a temporary triangulation, in order to keep the
triangulation I am working on untouched. Is there a way to copy the
triangulation (defined as parallel::distributed::Triangulation) to a
temporary triangulation? According to
http://www.dealii.org/developer/doxygen/deal.II/classparallel_1_1distributed_1_1Triangulation.html
there is no way to do that directly, is that correct?
Or is it more efficient to scale the original triangulation, write the
data, and re-scale it?
Rescaling is a cheap operation -- I'd just do that and the scale back
when you're done. On the other hand, copying is expensive and difficult,
so I'd avoid that if possible.
(It is possible that p::d::Triangulation has a member function
copy_from(), but I don't recall for sure.)
