We propose and analyze efficient preconditioners for solving systems of equations arising from the p-version for the finite element/boundary element coupling. The first preconditioner amounts to a block Jacobi method, whereas the second one is partly given by diagonal scaling. We use the generalized

โฆ Synopsis
An adaptive solver for large-scale hierarchic finite element systems has been developed. A decision-making methodology aimed at selecting an optimal solution strategy on the basis of estimated conditioning, sparsity and memory requirements for a given problem has been devised. Numerical experiments have been conducted on selected shell and 3-D problems in the range of 1000-100 000 degrees of freedom.

The aim is to control the spatial and time discretization errors below a prescribed error tolerance at all time levels. In the algorithm,
The scaled boundary รฟnite element method, alias the consistent inรฟnitesimal รฟnite element cell method, is developed starting from the di usion equation. Only the boundary of the medium is discretized with surface รฟnite elements yielding a reduction of the spatial dimension by one. No fundamental sol
We consider methods for adaptive updating of computational meshes during incremental loading of non-linear shell and solid structures. In particular, we focus on updating methods where the initial topology of the mesh is maintained. The movement of the mesh (the convective step) is decoupled from th
