H. Wilkinson Prize for Numerical Software, has been released. It is +available for free under an Open Source license from the deal.II homepage at + + https://www.dealii.org/ + +The major changes of this release are: + +- deal.II now requires C++11. + +- Support for curved geometries has been improved. Manifold descriptions + are now exclusively handled via manifold_ids and all compatibility code + that used boundary indicators has been removed. In addition, every + function in the GridGenerator namespace now attaches a default manifold + to the curved parts of the domain described by the generated mesh. + +- deal.II now has a dedicated particles module. The module provides a base + class Particle that represents a particle with position, an ID number and + a variable number of properties. They are jointly represented by a + ParticleHandler class that manages the storage and handling of all + particles. + +- deal.II gained dedicated, first-class support for automatic + differentiation libraries and various capabilities (taped and tapeless + ADOL-C, Sacado with dynamic forward, reverse, nested dynamic forward, and + nested reverse support for first and second derivatives). + +- Interfaces to a number of additional external libraries has been added. + deal.II can now be configured with optional support for Assimp, Gmsh, + nanoflann, ROL, ScaLAPACK and Sundials. + +- This release adds support for computations on GPUs, both, for matrix-based + and for matrix-free applications. For matrix-based applications, cuSPARSE + and cuSOLVER are used. Support for matrix-free computation on GPUs is + preliminary. For now, the evaluation of the operator is limited to meshes + without hanging-nodes. + +- The matrix-free infrastructure in deal.II was significantly overhauled for + the current release. The major new contribution is the support of face + integrals through a new class FEFaceEvaluation. + +- deal.II has made extensive use of both the Clang-Tidy and Coverity Scan + static analysis tools for detecting bugs and other issues in the code. + For example, around 260 issues were detected and fixed using the latter + tool. + +- LinearOperator, a flexible template class that implements the action of a + linear operator, now supports computations with Trilinos, Schur + complements, and linear constraints. This class is, as of this release, + the official replacement for about half a dozen similar (but less + general) classes, such as FilteredMatrix, IterativeInverse, and + PointerMatrix. + +- A number of non-standard, special-purpose quadrature rules have been + implemented. Among these are ones for truncating standard formulas to + simplical domains (QSimplex), singular transformations of the unit cell + to the unit simplex (QDuffy), composition of simplical quadrature rules + to a combined rule on the unit cell (QSplit), and transformation of the + unit square to polar coordinates (QTrianglePolar). + +- Support for complex-valued vectors at the same level as real-valued + vectors. + +- A new python tutorial program tutorial-1; as well as updates to step-37. + In addition, the separate code gallery of deal.II has gained a number of + new entries. + +- Improved support for user-defined run-time parameters: a new + ParameterAcceptor class has been added to the library. The class is + intended to be used as a base for any class that wants to handle + parameters using the ParameterHandler class. + +- New caching mechanism for expensive grid computations: we introduced a + new class GridTools::Cache that caches computationally intensive + information about a Triangulation. This class allows the user to query + some of the data structures constructed using functions in the GridTools + namespace. + +- More than 330 other features and bugfixes. + +For more information see +- the preprint at https://www.dealii.org/deal90-preprint.pdf +- the list of changes at + https://www.dealii.org/developer/doxygen/deal.II/changes_between_8_5_0_and_9_0_0.html + +The main features of deal.II are: +- Extensive documentation and 57 fully-functional example programs +- Support for dimension-independent programming +- Locally refined adaptive meshes +- Multigrid support +- A zoo of different finite elements +- Fast linear algebra +- Built-in support for shared memory and distributed parallel computing, + scaling from laptops to clusters with 100,000+ processor cores +- Interfaces to Trilinos, PETSc, METIS, UMFPACK and other external software +- Output for a wide variety of visualization platforms. + + +X X, on behalf of the deal.II developer team and many contributors. diff --git a/9.0/announce-short b/9.0/announce-short new file mode 100644 index 0000000..b7ee592 --- /dev/null +++ b/9.0/announce-short @@ -0,0 +1,26 @@ +Version 9.0.0 of deal.II, the object-oriented finite element library awarded +the J.
