Adaptive finite element code library

'deal.II' is a software library that supports finite element computations on adaptive 1d, 2d, and 3d meshes. It comes with mesh handling, supports a large number of finite elements, can input and output in various formats, and has a large collection of support classes. The handling of different space dimensions is hidden behind C++ templates; this lets users treat problems in different space dimensions simultaneously within the same program, and to switch dimensions simply by recompilation. This means users can test their application in 2d, and then run production runs in 3d without having to debug the program again. It comes with full documentation of all APIs and 18 example programs showing how to build finite element programs from simple to very complex. The documentation now runs about 4000 pages.
