Introduction

deal.II was originally meant to be a successor to the differential equation analysis library, a C++ library designed to use the adaptive finite element method for partial differential equation calculations. It uses state-of-the-art programming techniques to provide you with modern interfaces to complex data structures and algorithms that you need.

deal.II aims to quickly develop modern finite element code by using various tools frequently used in adaptive grids and finite element programs. Writing such procedures is not easy, and successful programs tend to become very large and complex. You are recommended to do this with a library that handles the details of grid processing and refinement, degree of freedom, grid input, and output of graphical format results. Similarly, the way that multiple space sizes are supported at a time allows programs to be written independently of the space size and run without causing memory consumption.
