Least-Squares Proper Generalized Decompositions for Weakly Coercive Elliptic Problems [PDF]
SIAM Journal on Scientific Computing, 2017 Summary: Proper generalized decompositions (PGDs) are a family of methods for efficiently solving high-dimensional partial differential equations (PDEs), which seek to find a low-rank approximation to the solution of the PDE a priori. Convergence of PGD algorithms can only be proven for problems which are continuous, symmetric, and strongly coercive ...

Composite beam finite element based on the Proper Generalized Decomposition [PDF]
Computers & Structures, 2012 In this paper, a finite element based on the Proper Generalized Decomposition is presented for the analysis of bi-dimensional laminated beams. We propose to approximate the displacement field as a sum of separated functions of x (axial coordinate) and z (transverse coordinate).

Harmonic-Modal Hybrid Reduced Order Model for the Efficient Integration of Non-Linear Soil Dynamics
Applied Sciences, 2020 Nonlinear behavior of soils during a seismic event has a predominant role in current site response analysis. Soil response analysis, and more concretely laboratory data, indicate that the stress-strain relationship of soils is nonlinear and exhibits ...

A Proper Generalized Decomposition-Based Solver for Nonlinear Magnetothermal Problems [PDF]
IEEE Transactions on Magnetics, 2016 This paper investigates solving coupled magnetothermal problems through a proper generalized decomposition-based non-incremental approach. The magnetodynamic and thermodynamic problems are strongly coupled as the electric material property changes with the temperature while the temperature field evolves due to the Joule heat generated by induced ...

An Aerodynamic Optimization Approach for Wind Turbine Blades Using Proper Generalized Decomposition
EnergiesA new approach for optimizing the blade profile of a horizontal axis wind turbine is proposed in this paper, based on the combination of the Blade Element Momentum (BEM) method and Proper Generalized Decomposition (PGD).

Proper Generalized Decomposition Applied on a Rotating Electrical Machine [PDF]
IEEE Transactions on Magnetics, 2018 The proper generalized decomposition (PGD) is a model order reduction method which allows to reduce the computational time of a numerical problem by seeking for a separated representation of the solution. The PGD has been already applied to study an electrical machine but at standstill without accounting the motion of the rotor.
