A local multiple proper generalized decomposition based on the partition of unity
(John Wiley & sons, 2019-10-12)
Article
Accés obertIt is well known that model order reduction techniques that project the solution of the problem at hand onto alow-dimensional subspace present difficulties when this solution lies on a non-linear manifold. To overcomethese ... -
A non-intrusive proper generalized decomposition scheme with application in biomechanics
(John Wiley & Sons, 2017-09-07)
Article
Accés obertProper generalized decomposition (PGD) is often used for multiquery and fast-response simulations. It is a powerful tool alleviating the curse of dimensionality affecting multiparametric partial differential equations. ... -
A numerical study on hydraulic fracturing problems via the proper generalized decomposition method
(2020-02-01)
Article
Accés obertThe hydraulic fracturing is a nonlinear, fluid-solid coupling and transient problem, in most cases it is always time-consuming to simulate this process numerically. In recent years, although many numerical methods were ... -
A Reduced Order Modeling approach for optimal allocation of Distributed Generation in power distribution systems
(2016)
Text en actes de congrés
Accés restringit per política de l'editorialThis paper presents an “offline-online” strategy for optimal allocation and sizing of Distributed Generation. In traditional optimization approaches, each function evaluation requires the solution of a power flow problem, ... -
Efficiency and accuracy of high-order computations and reduced order modelling in coastal engineering wave propagation problems
(2012)
Text en actes de congrés
Accés restringit per política de l'editorialSeveral numerical issues have to be considered when solving wave propagation problems, between which there are the artificial boundary conditions, the small geometrical features that can be influential or the variable ... -
Error estimation for proper generalized decomposition solutions: dual analysis and adaptivity for quantities of interest
(2021-02-15)
Article
Accés obertWhen designing a structure or engineering a component, it is crucial to use methods that provide fast and reliable solutions, so that a large number of design options can be assessed. In this context, the proper generalized ... -
Multiscale proper generalized decomposition based on the partition of unity
(John Wiley & sons, 2019-11-09)
Article
Accés obertSolutions of partial differential equations could exhibit a multiscale behavior. Standard discretization techniques are constraints to mesh up to the finest scale to predict accurately the response of the system. The ... -
Proper generalized decomposition solutions within a domain decomposition strategy
(John Wiley & sons, 2018-03-30)
Article
Accés obertDomain Decomposition strategies and the Proper Generalized Decomposition are efficiently combined to obtain a fast evaluation of the solution approximation in parameterized elliptic problems with complex geometries. The ...
