Why it does not work when I use a vector of triangulations? And any
suggestions when using a collection of triangulations?
The C++ standard says that what you can store in a std::vector needs to
be copyable (because std::vector dynamically resizes how many elements
it stores, and so needs to be able to copy things from the old storage
to the new). Consequently, you can't store a Triangulation in a vector.
But, you can store *pointers* to Triangulations in std::vector, or even
better something like
std_cxx11::shared_ptr<Triangulation<dim>>
The pointers are copyable, even if the triangulations are not.
In addition, it is said that copy_triangulation() is not efficient.
That's not true. The operation is *efficient*. It's just not *cheap*,
because it has to copy *lots* of data.
