Application of the Proper Generalized Decomposition to Solve MagnetoElectric Problem
Article dans une revue avec comité de lecture
Among the model order reduction techniques, the Proper Generalized Decomposition (PGD) has shown its efficiency to solve a large number of engineering problems. In this article, the PGD approach is applied to solve a multi-physics problem based on a magnetoelectric device. A reduced model is developed to study the device in its environment based on an Offline/Online approach. In the Offline step, two specific imulations are performed in order to build a PGD reduced model. Then, we obtain a model very well fitted to study in the Online stage the influence of parameters like the frequency or the load. The reduced model of the device is coupled with an electric load (R-L) to illustrate the possibility offered by the PGD.

Article dans une revue avec comité de lecturePIERQUIN, Antoine; HENNERON, Thomas; CLENET, Stéphane; BRISSET, Stephane (Wydawnictwo Czasopism i Ksia̜żek Technicznych Sigma, 2015)The modelling of a multirate system -composed of components with heterogeneous time constants- can be done using fixed-point method. This method allows a time-discretization of each subsystem with respect to its own time ...
Multirate coupling of controlled rectifier and non-linear finite element model based on Waveform Relaxation Method Article dans une revue avec comité de lectureHENNERON, Thomas; CLENET, Stéphane; PIERQUIN, Antoine; BRISSET, Stéphane (Institute of Electrical and Electronics Engineers, 2016)To study a multirate system, each subsystem can be solved by a dedicated sofware with respect to the physical problem and the time constant. Then, the problem is the coupling of the solutions of the subsystems. The Waveform ...
Benefits of Waveform Relaxation Method and Output Space Mapping for the Optimization of Multirate Systems Article dans une revue avec comité de lecturePIERQUIN, Antoine; BRISSET, Stéphane; HENNERON, Thomas; CLENET, Stéphane (Institute of Electrical and Electronics Engineers, 2014)We present an optimization problem that requires to model a multirate system, composed of subsystems with different time constants. We use waveform relaxation method in order to simulate such a system. But computation time ...
Model-Order Reduction of Magnetoquasi-Static Problems Based on POD and Arnoldi-Based Krylov Methods Communication avec actePIERQUIN, Antoine; HENNERON, Thomas; CLENET, Stéphane; BRISSET, Stéphane (IEEE, 2015)The proper orthogonal decomposition method and Arnoldi-based Krylov projection method are investigated in order to reduce a finite-element model of a quasi-static problem. Both methods are compared on an academic example ...
Mesh Deformation Based on Radial Basis Function Interpolation Applied to Low-Frequency Electromagnetic Problem Article dans une revue avec comité de lectureHENNERON, Thomas; PIERQUIN, Antoine; CLENET, Stéphane (Institute of Electrical and Electronics Engineers, 2019)In order to take into account a modification of the geometry during an optimization process or due to a physical phenomenon, a deformation of the elements of the spatial discretization is preferable to conserve a conformal ...
