Т Е Х Н И Ч Е С К А Я   Л И Т Е Р А Т У Р А: ALBERT: An adaptive hierarchical finite element toolbox
Краткое описание:
"ALBERT is an Adaptive multi-Level finite element toolbox using
Bisectioning refinement and Error control by Residual Techniques.
Its design is based on appropriate data structures holding
geometric, finite element, and algebraic information. Using such
data structures, abstract adaptive methods for stationary and time
dependent problems, assembly tools for discrete systems, and
dimension dependent tasks like mesh modifications can be provided
in a library. This allows dimension-independent development and
programming of a general class of applications. In ALBERT,
hierarchical 2d and 3d meshes are stored in binary trees. Several
sets of finite elements can be used on the same mesh, either using
predefined ones, or by adding new sets for special applications.
Depending on the currently used finite element spaces, all degrees
of freedom are automatically managed during mesh modifications.
Tools for assembling system matrices and right hand sides as well
as (linear) system solvers are included."
