Identification of the Dynamic Properties of the Residential Tower New Orleans

This paper describes the application of the Frequency Domain Decomposition (FDD) technique on measured acceleration data on the residential tower New Orleans in Rotterdam, the Netherlands. The goal of this study is to determine and analyse multiple natural frequencies and mode shapes of this tower. A measurement campaign was setup on the 158 m...

Efficient estimation of space varying parameters in numerical models using non-intrusive subdomain reduced order modeling

A reduced order modeling algorithm for the estimation of space varying parameter patterns in numerical models is proposed. In this approach domain decomposition is applied to construct separate approximations to the numerical model in every subdomain. We introduce a new local parameterization that decouples the computational cost of the...

Efficient analysis of arrays of compact metallic elements devoted to satellite SAR

A fully metallic monopole element is proposed for satellite SAR antennas. This element has significant gain in the broadside direction thanks to its curved arm. This element is then studied in a large sparse array. A fast analysis technique is presented in order to solve for the currents of few hundreds elements, which correspond approximately...

The deflation accelerated schwarz method for CFD

Accurate simulation of glass melting furnaces requires the solution of very large linear algebraic systems of equations. To solve these equations efficiently a Schwarz domain decomposition (multi-block) method can be used. However, it can be observed that the convergence of the Schwarz method deteriorates when a large number of subdomains is...
