I am running the first example "first_grid". I want to know does deal.ii
support the defination of the boundary name and output  it to a readable file.
I have output the grid to ucd  file , but no boundary infors are stored in the
ucd file.
 Could you please give me some advices.

You might want to read through the documentation of the GridOut class. There
are ways to also output boundary indicators, at least for some formats, via
the various *Flags data structures.
