The Global ETD Search service is a free service for researchers
to find electronic theses and dissertations. This service is
provided by the
Networked Digital Library of Theses and Dissertations.
Our metadata is collected from universities around the world. If you manage a university/consortium/country archive and want to be added, details can be found on the NDLTD website.

A fast and efficient algorithm to compute BPX- and overlapping preconditioner for adaptive 3D-FEMEibner, Tino 17 September 2008 (has links) (PDF)
In this paper we consider the well-known BPX-preconditioner in
conjunction with adaptive FEM. We present an algorithm which enables
us to compute the preconditioner with optimal complexity by a total of
only O(DoF) additional memory. Furthermore, we show how to combine
the BPX-preconditioner with an overlapping Additive-Schwarz-preconditioner
to obtain a preconditioner for finite element spaces with
arbitrary polynomial degree distributions. Numerical examples
illustrate the efficiency of the algorithms.
