An a posteriori error analysis for Boussinesq equations is derived in this article. Then we compare this new estimate with a previous one developed for a regularized version of Boussinesq equations in a previous work.

β¦ Synopsis
An rh-method, which combines r-and h-methods, is proposed for cost-eective adaptive FE analysis in twodimensional linear elastic problems. Through various numerical test examples, the rh-method is compared with the h-method. From these examples it is concluded that the rh-method has the advantages of both the r-and h-methods, so that the rh-method can minimize the computational time required for the adaptive analysis. The algorithm of the rh-method can be implemented easily in existing h-adaptive FE codes, since the r-method is independently combined with the h-method.

This paper presents a force-based finite element method that involves eigen-space transformation of element stiffness matrices in the first analysis. In each subsequent analysis ('reanalysis') associated with structural variations, the solution obtained previously is modified making use of intrinsic
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
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
This article describes an error measurement and mesh optimization method for finite elements in non-linear geometry problems. The error calculation is adapted from a method developed by Ladeveze, based on constructing a local statically admissible stress field. The particular difficulty in non-linea
