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?
