FEAST - Finite Element Analysis and Solution Tools
FEAST is our next-generation Finite Element software that implements many ideas and concepts of hardware-oriented numerics. FEAST is explicitly designed for large-scale runs on supercomputers. Its core features include:
- All linear systems are solved by a hybrid non-overlapping domain decomposition parallel multilevel/multigrid method called ScaRC, short for Scalable Recursive Clustering. ScaRC works on what we call globally unstructured locally structured grids to achieve both geometric flexibility and scalability at large and maximum local performance. All local problems are structured, and this structure is exploited in the design of fast local multigrid solvers that achieve a substantial fraction of the available peak performance.
- FEAST is able to exploit GPUs as co-processors, which happens to be one of the results of my PhD research.
- Applications exist for solid mechanics and fluid dynamics.
More info, including a detailed bibliography, is available on the project page. As FEAST still undergoes massive changes (like most actively developed research codes), we haven't made a public release yet, simply because we do not have the time to support it. This may change in the future.
HONEI - Hardware-Oriented Numerics Efficiently Implemented
HONEI aims at developing a set of heavily templated C++ libraries to facilitate the development of scientific software on heterogeneous architectures. The underlying idea is to abstract from the hardware as much as possible, and ease the implementation of user-provided application-specific kernels where unavoidable. HONEI provides a rich set of infrastructure for multicore CPUs, GPUs, the Cell processor and MPI-based clusters. Please check the project web page for details.
DeViSoR GRID3D
DeViSoR GRID3D is an effort to implement a FEM preprocessor, including mesh generation, geometry definition etc. in an intuitive point-and-click vector drawing GUI. This software is written entirely in Java. I used to work a lot on this project, in particular for my diploma thesis. You can download a fully documented version including source code and manuals from the corresponding project page.
FeatFlow
FeatFlow is a scientific code for 2D and 3D stationary and instationary Navier-Stokes simulations. I contributed with my diploma thesis (some new mesh smoothers and a geometry projection scheme) and wrote parts of the GNU-make based installer for the current version 1.3. FeatFlow is implemented in good-old Fortran 77. FeatFlow is available for download free of charge, including the source code, a library of results, and tons of other information.
