A mathematical theory for mass lumping and its generalization with applications to isogeometric analysis

Annalisa Buffa, Espen Sande, Yannis Dirk Voet

Explicit time integration schemes coupled with Galerkin discretizations of time-dependent partial differential equations require solving a linear system with the mass matrix at each time step. For applications in structural dynamics, the solution of the li ...

Torque Computation With the Isogeometric Mortar Method for the Simulation of Electric Machines

Bernard Kapidani, Rafael Vazquez Hernandez

In this work, isogeometric mortaring is used for the simulation of a six-pole permanent magnet synchronous machine. Isogeometric mortaring is especially well suited for the efficient computation of rotating electric machines, as it allows for an exact geom ...

A projected super-penalty method for the C1-coupling of multi-patch isogeometric Kirchhoff plates

Annalisa Buffa, Luca Coradello

This work focuses on the development of a super-penalty strategy based on the L2-projection of suitable coupling terms to achieve C1-continuity between non-conforming multi-patch isogeometric Kirchhoff plates. In particular, the choice of penalty parameter ...

Reduction techniques for PDEs built upon Reduced Basis and Domain Decomposition Methods with applications to hemodynamics

Luca Pegolotti

This thesis focuses on the development and validation of a reduced order technique for cardiovascular simulations. The method is based on the combined use of the Reduced Basis method and a Domain Decomposition approach and can be seen as a particular imple ...

Quelle habitabilité pour demain? Explorations nyonnaises vers une métropole alpino-lémanique

Noélie Marion Charlotte Lecoanet

La croissance de la Métropole alpino-lémanique est confrontée à des défis complexes et contradictoires. En effet, le canton de Vaud souhaite la concentrer en densifiant les agglomérations existantes. Cependant, la nécessité de s'éloigner de ces conceptions ...

Isogeometric Mortar Coupling for Electromagnetic Problems

Annalisa Buffa, Rafael Vazquez Hernandez

This paper discusses and analyzes two domain decomposition approaches for electromagnetic problems that allow the combination of domains discretized by either Nédélec-type polynomial finite elements or spline-based isogeometric analysis. The first approach ...

Explicit dynamic approach for unbounded domains in frictional contact with Rate and State laws

Jean-François Molinari, Roozbeh Rezakhani

The paper explores the ability of an explicit time integration procedure to simulate the dynamics of shear rupture between unbounded elastic blocks on frictional interface, modeled with the finite element method. The behaviour of the interface is governed ...

A priori error for unilateral contact problems with Lagrange multipliers and isogeometric analysis

Annalisa Buffa, Pablo Antolin Sanchez, Mathieu Jonathan Fabre

In this paper, we consider unilateral contact problem without friction between a rigid body and deformable one in the framework of isogeometric analysis. We present the theoretical analysis of the mixed problem. For the displacement, we use the pushforward ...

Synergies entre la production hydroélectrique et la protection contre les crues : cas d'étude de la Sihl en Suisse

Anton Schleiss, Pedro Filipe De Almeida Manso, Frédéric Jordan, Fränz Zeimetz

Située à la confluence de deux cours d'eau – la Limmat et la Sihl – la ville de Zurich a toujours dû faire face aux crues. Suite aux crues de 2005, un projet de dérivation de la Sihl vers le lac de Zurich en amont de la ville a été lancé. En alternative à ...
