Torsion Analysis of High-Rise Buildings using Quadrilateral Panel Elements with Drilling D.O.F.s

Generally, the finite element method is a powerful procedure for analysis of tall buildings. Yet, it should be noted that there are some problems in the application of many finite elements to the analysis of tall building structures. The presence of artificial flexure and parasitic shear effects in many lower order plane stress and membrane elements, cause the numerical procedure to converge in...

Mixed Methods Using Standard Conforming Finite Elements

We investigate the mixed finite element method (MFEM) for solving a second order elliptic problem with a lowest order term, as might arise in the simulation of single phase flow in porous media. We find that traditional mixed finite element spaces are not necessary when a positive lowest order (i.e., reaction) term is present. Hence we propose to use standard conforming finite elements Qk × (Qk...

CSIR Centre for Mathematical Modelling and Computer Simulation MAKING SENSE OF THE QUADRILATERAL AREA COORDINATE MEMBRANE ELEMENTS

The introduction of the Quadrilateral Area Coordinate (QAC) membrane elements has generated more heat than light on the subject of why distorted membrane elements perform very poorly. The canonical guidelines for construction of robust elements are continuity and completeness. It is known that isoparametric (or parametric) quadrilateral membrane elements satisfy the continuity requirements alwa...

Nonstandard coarse spaces and Schwarz methods for elliptic problems with discontinuous coefficients using non-conforming elements

Two-level domain decomposition methods are developed for a simple nonconforming approximation of second order elliptic problems. A bound is established for the condition number of these iterative methods, that grows only logarithmically with the number of degrees of freedom in each subregion. This bound holds for two and three dimensions and is independent of jumps in the value of the coefficie...

Solution methods for the Cahn-Hilliard equation discretized by conforming and non-conforming finite elements

In this work we consider preconditioned iterative solution methods for numerical simulations of multiphase flow problems, modelled by the Cahn-Hilliard equation. We focus on the construction and efficiency of various preconditioning techniques and the effect of two discretization methods – conforming and non-conforming finite elements spaces – on those techniques.
