It is available from the deal.II home-page at + + http://www.dealii.org/ + +Version 5.1 contains a number of improvements over previous versions. In +particular, it contains a version of the sparse direct solver package UMFPack, +as well as corresponding interfaces to use it from within deal.II. + +In addition to this, the most noteworthy changes are: +- Vectors and matrices built on top of PETSc objects are now completely + integrated. In particular, one can build block vectors and matrices out of + them +- In 3d, Lagrange elements now implement hanging node constraints for all + polynomial orders, not only for the first few +- Several classes have been optimized to use algorithms with a better + complexity in terms of memory use or run time +- Support for DLLs on Microsoft Windows. + +A comprehensive list of new features and fixed bugs can be found at + http://www.dealii.org/news/5.0.0-vs-5.1.0.html + +All main features of the previous versions have been continued and improved: +- Support for dimension-independent programming +- Extensive documentation and working example programs +- Locally refined grids +- A zoo of different finite elements +- Fast linear algebra +- Built-in support for symmetric multi-processing (SMP) +- Output for a variety of visualization platforms. + +deal.II can be downloaded for free and is distributed under an Open +Source license. + + +Wolfgang Bangerth, Ralf Hartmann, Guido Kanschat, the deal.II team
