(Adaptive multi-Level finite element toolbox using Bisectioning
refinement and Error control by Residual Techniques)
Supplies modules for local grid modifications and adaptive methods for stationary and timedependent problems in two and three space dimensions. The mesh is stored in hierarchical data structures. Several sets of finite elements of various order can be used on the same mesh. Tools for assembling system matrices and right hand sides are included
GRAPE (GRAphical Programming Environment)GRAPE is a package for mathematical visualization. It has been particularly effective in the fields of differential geometry and continuum mechanics. But it will probably help to understand any other problem involving the numerics of partial differential equations or the need of advanced three-dimensional computer graphics.
Iterative Löser für lineare Gleichungssysteme
This package contains easy-to-use functions for approximately solving sparse systems of linear equations by implicit methods, written in C++. For making most efficient use of the sparsity pattern and the spirit of implicit solvers, the user has to provide the application of the matrix to vectors; he is absolutely free in designing his matrix.
DUNE: eine Schnittstellen-basierte FV/FEM BibliothekDUNE ist eine Schnittstellen--basierte Entwicklungsumgebung zur Implementierung effizienter Finite Elemente oder Finite Volumen Verfahren. DUNE wird seit Anfang 2004 von unserer Argeitsgruppe in Zusammenarbeit mit den Arbeitsgruppen von P. Bastian (Heidelberg) und R. Kornhuber (Berlin) entwickelt.
The ALUGrid Library For numerical computation in the field of fluid dynamics an flexible implementation of a discretization grid is needed. The ALUGrid Library provides both hexahedral and tetrahedral grids which can be locally adapted and when used for parallel computations the decomposition of the domain can be recomputed.
