Roozbeh Sanaei's picture

deal.II is a C++ program library targeted at adaptive
finite elements and error estimation. It uses state-of-the-art programming
techniques of the C++ programming language to offer you a modern interface to
the complex data structures and algorithms required for adaptivity and enables
you to use a variety of finite elements in one, two, and three space dimensions,
as well as time-dependent problems.

The main aim of deal.II is to enable development of modern
finite element algorithms, using among other aspects sophisticated error
estimators and adaptive meshes. Writing such programs is a non-trivial task, and
successful programs tend to become very large and complex. We therefore believe
that this is best done using a program library that frees the application
programmer from aspects like grid handling and refinement, handling of degrees
of freedom, input of meshes and output of results in graphics formats, and the
like. Also, support for several space dimensions at once is included in a way
such that programs can be written independent of the space dimension without
unreasonable penalties on run-time and memory consumption.
