Conjugate gradient for ill-posed problems: regularization by preconditioning, preconditioning by regularization

Ahmed Chabib, Jean-Francois Witz, Vincent Magnier +1

This paper investigates using the conjugate gradient iterative solver for ill-posed problems. We show that preconditioner and Tikhonov-regularization work in conjunction. In partic…

On the implementation in Abaqus of the global--local iterative coupling and acceleration techniques

Omar Bettinotti, Stéphane Guinard, Eric Véron +1

This paper presents results and convergence study of the Global--Local Iterative Coupling through the implementation in the commercial software Abaqus making use of the co-simulati…

PGD reduced-order modeling for structural dynamics applications

Clément Vella, Serge Prudhomme

We propose in this paper a Proper Generalized Decomposition (PGD) approach for the solution of problems in linear elastodynamics. The novelty of the work lies in the development of…

Asynchronous scalable version of the Global-Local non-invasive coupling

Ahmed El Kerim, Pierre Gosselet, Frederic Magoules

The Global-Local non-invasive coupling is an improvement of the submodeling technique, which permits to locally enhance structure computations by introducing patches with refined m…

Constructing the Hamiltonian from the behaviour of a dynamical system by proper symplectic decomposition

Nima Shirafkan, Pierre Gosselet, Franz Bamer +3

The modal analysis is revisited through the symplectic formalism, what leads to two intertwined eigenproblems. Studying the properties of the solutions, we prove that they form a c…
