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…
