Guillard, H. (author), Labois, M. (author)This paper presents a hierarchy of compressible two-phase flow models. It is shown that using Chapman-Enskog expansions in the limit of zero relaxation time toward the various equilibria that exist in these flows, a full set of models of decreasing complexity can be constructed. At the top of this hierarchy, we have a complete seven equation...conference paper 2006

Murea, C.M. (author), Vazquez, C. (author)We study the fluid-structure coupled problem between an incompressible fluid and an elastic curved arch. The fluid flow is modeled by 2-D steady Stokes equations with normal velocity boundary condition on the curved interface and the arch verifies a particular 1-D case of the thin shell theory of Koiter. We present an optimal control formulation...conference paper 2006

Bungartz, H.J. (author), Mehl, M. (author)The simulation of multiphysical scenarios has become a more and more important task of scientific computing within the last years. Due to their simplicity compared to monolithic approaches (solving a unique model for the whole scenario), partitioned approaches are widespread. They allow for a reusage of existing and established solvers for the...conference paper 2006

Sevilla, R. (author), Fernández-Méndez, S. (author), Huerta, A. (author)An improvement of the classical finite element method is proposed. It considers an exact representation of the geometry by means of the usual CAD description of the boundary with Non-Uniform Rational B-Splines (NURBS). For elements not intersecting the boundary, a standard finite element interpolation and numerical integration is used....conference paper 2006

Guermond, J.L. (author), Laguerre, R. (author), Léorat, J. (author), Nore, C. (author)The Maxwell equations in the MHD limit in heterogeneous domains composed of conducting and nonconducting regions are solved by using Lagrange finite elements and by enforcing continuities across interfaces using an interior penalty technique. The method is shown to be stable and convergent and is validated by convergence tests. It is used to...conference paper 2006

Ganesan, S. (author), Tobiska, L. (author)This work is devoted to the accurate simulation of incompressible two phase flows. The core of our methodology is the use of interface resolving meshes and the arbitrary Lagrangian-Eulerian (ALE) description of the fluid kinematics. Our numerical scheme is based on second order finite elements, a fractional step ? time discretisation, and a...conference paper 2006

Moes, C.C.M. (author)We are using many designed artefacts in our daily life. These artefacts are typically in physical interaction with the human body, and cause stresses and deformations inside the tissues. When these stresses exceed a given level, the proper physiological functioning of the tissues is limited, and ergonomics discomfort or even medical...doctoral thesis 2004

Kok, A.W.M. (author)The analysis of structures subjected to fast moving loads is a subject of growing interest in railway and pavement engineering. The applications of transient analyses using finite element models, however, are still very limited. The faster a load moves the more elements we need to model the structure. Even at fast workstations and main frame...journal article 2000
