N2  -   An overview of the software design and data abstraction   decisions chosen for deal.II, a general purpose finite element   library written in C++, is given. The library uses advanced   object-oriented and data encapsulation techniques to break finite   element implementations into smaller blocks that can be arranged   to fit users requirements. Through this approach, deal.II supports a large number of   different applications covering a wide range of scientific areas,   programming methodologies, and application-specific algorithms, without imposing   a rigid framework into which they have to fit. A judicious use of   programming techniques allows to avoid the computational costs frequently   associated with abstract object-oriented class libraries.   The paper presents a detailed description of the abstractions chosen for   defining geometric information of meshes and the handling of degrees   of freedom associated with finite element spaces, as well as   of linear algebra, input/output capabilities and of   interfaces to other software, such as visualization tools.  Finally,   some results obtained with applications built atop   deal.II are shown to demonstrate the powerful capabilities of this toolbox.
