Hi all,
I am using multiple meshes in deal.ii, so that I need to read input files
from Gmsh. For example, I have a collection of triangulations, e.g.,
tria_1, tria_2, ..., and tria_10. When I stay on a specific mesh, I need a
corresponding triangulation. I used a vector to store all the
triangulations, and then use copy_triangulation to call a specific
triangulation, like follows,
std::vector<Triangulation<2>> triangulation_vector(10, Triangulation<2>());
triangulation.clear();
triangulation.copy_triangulation(triangulation_vector[0]);
However, it shows
"The name and call sequence of the exception was:
ExcMessage ("You are not allowed to call this constructor " "because
copying Triangulation objects is not " "allowed. Use
Triangulation::copy_from() instead.")
"
It works if I call the name of triangulation directly like tria_1, but it
is difficult to use.
triangulation.clear();
triangulation.copy_triangulation(tria_1);
Why it does not work when I use a vector of triangulations? And any
suggestions when using a collection of triangulations?
In addition, it is said that copy_triangulation() is not efficient. The
most direct way for my case is to read the corresponding Gmsh file
everytime I need it. But it would be way more time-consuming.
Thank you!
Best,
Chenchen
