I intend to use deal.ii on my PhD and start from the beginning (step-1)
to learn how to use deal.ii (I suspect that it is the better way to

I'm using Visual Studio Code to run step-1 (with properly C++ and CMake
Tools extensions). In the first run I faced a question: how to inspect
triangulation? When I run step on debugging mode, triangulation seems to
be empty, it just shows {...}, unlike grid_out, where I can see
everything that was set up, as can be seen in the figure.
Does someone know if this is a problem with VS Code or is something
related to deal.ii?
Diego,
I don't know Visual Studio well enough to tell what specifically is
wrong. But you will not likely find anything very useful when you
inspect Triangulation objects: This class consists of a number of very
complicated data structures that together describe a triangulation, but
they are not obvious to understand. For example, you might think that a
Triangulation essentially consists of a
std::vector<Cell> cells;
structure where 'Cell' is where we store all of the information about
each cell. But that is not true -- in fact, the information about cells
is scattered across several dozen arrays grouped into a number of
different classes. This would make it quite difficult to understand
anything about the triangulation by looking at its member variables, but
is what is necessary to make this class work efficiently on modern
architectures.
In other words, I can't help you with your immediate problem, but think
that even if one could work out this case, you would not learn much from it.
Best
W.
