The deal.II code gallery contains a collection of programs based on deal.II that were contributed by others to serve as starting points for more complex applications. The code gallery is an extension of the tutorial in that the programs are intended to show how applications can be implemented with deal.II, but without the requirement to have these code documented at the same, extensive level as used in the tutorial. Instructions for obtaining the code gallery programs can be found at http://dealii.org/code-gallery.html .

Warning: The programs that form part of the code gallery are contributed by others and are not part of deal.II itself. The deal.II authors make no assurances that these programs are documented in any reasonable way, nor that the programs are in fact correct. Please contact the authors of the code gallery programs if you have questions.

The code gallery currently consists of the following programs (with connections to other programs shown in the graph on the tutorial page):
