Current Release (Version 2.0)

Version 2.0 of HiFlow3 provides major and essential new features in several of its modules: The mesh module provides extended support for adaptively refined meshes by means of the p4est library. Furthermore, pyramid elements are now supported for 3D geometries. The DoF/FEM modules now provide the ability for Discontinuous Galerkin (DG) discretizations. The linear algebra module ships with new solvers and preconditioners (Schur complement and energy-efficient geometric multigrid) as well as interfaces to further third-party libraries (Hypre, PETSc, SLEPc). Furthermore, new (parallel) matrix and vector implementations for Polynomal Chaos Expansion (PCE) based discretizations are available. Problems related to Uncertainty Quantification (UQ) for PDEs can be solved using these techniques. Finally, tools for goal oriented adaptivity are introduced.

The new features are documented in several new examples and tutorials.
