Carol S. WOODWARD
Carol S. WOODWARD, Lawrence Livermore National Laboratory, USA: A reconsideration of fixed point methods for nonlinear systems Newton-Krylov methods have proven to be very effective for solution of large-scale, nonlinear systems of equations resulting from discretizations of PDEs. However, increasing complexities and newer models are giving rise to nonlinear systems with characteristics that challenge this …

Roland BECKER
Roland BECKER, Université de Pau: Nitsche’s method for incompressible flows In this talk we study the finite element formulation of general boundary conditions for incompressible flow problems. Distinguishing between the contributions from the inviscid and viscid parts of the equations, we use Nitsche’s method to develop a discrete weighted weak formulation valid for all values …

Jean-François BABADJIAN
Jean-François BABADJIAN, Laboratoire Jacques-Louis Lions, University Paris 6: Une approche variationnelle de la mécanique de la rupture Dans cet exposé, nous présenterons un modèle variationnel en mécanique de la rupture fragile introduit par Francfort et Marigo. Celui-ci repose sur une idée originale due a Griffith qui postule l’existence d’une énergie de surface. La propagation des …

Enrique D. FERNANDEZ-NIETO, U. of Sevilla, Spain and Tomás MORALES DE LUNA, Cordoba University, Spain: Some advances on the mathematical modelling and numerical simulation of sediment transport: bedload and suspension This talk focuses on several aspects related to the matematical modelling and simulation of sediment transport in rivers and coastal areas. Sediment transport is usually …
