The code gallery is a collection of codes based on
deal.II contributed by deal.II
users. These codes typically solve problems more complicated than
those in the deal.II tutorial. Their intention is to solve actual
problems, rather than demonstrate particular aspects of deal.II.
The code gallery is, however, cross linked from the
set of tutorials.
To build the doxygen documentation, check out the code gallery git repository in a directory parallel to the <path/to/deal.II>/examples/
directory, and then build the deal.II
documentation as described in the readme.
It will pick up the code gallery and create joint documentation for the tutorial and the code gallery.
