Acceleration of Born series by change of variables
(2021-09)
Article
Accés obertIn this work, we propose a method to enhance the convergence of the Born series. The Born series is widely used in scattering theory, but its convergence is only guaranteed under certain restrictive conditions which limit ... -
An overlapping domain decomposition method for the solution of parametric elliptic problems via proper generalized decomposition
(Elsevier, 2024-01-01)
Article
Accés obertA non-intrusive proper generalized decomposition (PGD) strategy, coupled with an overlapping domain decomposition (DD) method, is proposed to efficiently construct surrogate models of parametric linear elliptic problems. ... -
Numbering along advection for Gauss-Seidel and bidiagonal preconditioners
(Barcelona Supercomputing Center, 2015-05-05)
Text en actes de congrés
Accés obertDomain decomposition methods (DDM) are often chosen to precondition sparse linear systems of equations, as they are famous to well-improve the convergence of iterative solvers. But at the same time, they are difficult to ... -
The domain interface method in non-conforming domain decomposition multifield problemsdomain decomposition multifield problems
(2016-12)
Article
Accés obertThe Domain Interface Method (DIM) is extended in this contribution for the case of mixed fields as encountered in multiphysics problems. The essence of the non-conforming domain decomposition technique consists in a ... -
The domain interface method: a general-purpose non-intrusive technique for non-conforming domain decomposition problems
(2016-04)
Article
Accés obertA domain decomposition technique is proposed which is capable of properly connecting arbitrary non-conforming interfaces. The strategy essentially consists in considering a fictitious zero-width interface between the ...
