Version 9.7.0 of deal.II, the object-oriented finite element library
awarded the J. H. Wilkinson Prize for Numerical Software and the
SIAM/ACM Prize in Computational Science and Engineering, 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:
- Three new tutorial programs, showing how to deal with non-local degrees
of freedom (step-93), matrix-free CutFEM methods (step-95), and
curl-curl
problems (step-97).
- The introduction of an optimized MappingP1 class for affine mappings
on simplex elements
- Improved portability for matrix-free operations through the use of
Kokkos
- Task-based programming support is now based on the Taskflow library, in
addition to the existing support via the Threading Building Blocks
(TBB).
- Many updates to external libraries, including to Kokkos, MUMPS, PSBLAS,
Magic Enum, and ArborX, as well as to Trilinos' Tpetra stack.
- deal.II can now build C++20-style modules.

The main features of deal.II are:
- Extensive documentation and 88 working example programs
- Support for dimension-independent programming
- Locally refined adaptive meshes and multigrid support
- A zoo of different finite elements
- Built-in support for shared memory and distributed parallel
computing, scaling from laptops to clusters with 300,000+ of
processor cores
- Interfaces to Trilinos, PETSc, SUNDIALS, UMFPACK and many other
external software packages
- Input and output for a wide variety of meshing and visualization
platforms.
