ALBERTA

Roozbeh Sanaei's picture

ALBERTA is an
Adaptive multiLevel finite element toolbox using
Bisectioning refinement and Error control by Residual
Techniques for scientific Applications. Its design is based on
appropriate data structures holding geometrical, 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 ALBERTA, 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.
