Isogeometric Schwarz Preconditioners with Generalized B-Splines for the Biharmonic Problem

open access: yesAxioms, 2023
We construct an overlapping additive Schwarz preconditioner for the biharmonic Dirichlet problems discretized by isogeometric analysis based on generalized B-splines (GB-splines) and analyze its optimal convergence rate bound that is cubic in the ratio ...

On the Convergence of the Damped Additive Schwarz Methods and the Subdomain Coloring

open access: yesMathematical and Computational Applications, 2022
In this paper, we consider that the subdomains of the domain decomposition are colored such that the subdomains with the same color do not intersect and introduce and analyze the convergence of a damped additive Schwarz method related to such a subdomain

Effect of the frequency spacing on modal damping estimation of a double-layer grid [PDF]

open access: yesمهندسی عمران شریف, 2021
Although natural frequencies and mode shapes can be accurately measured by dynamic tests, error bounds in values of damping estimation can be large. Since damping strongly influences the design and control of structures, efforts are made to find the ...

Comparison of FETI-based domain decomposition methods for topology optimization problems

open access: yesActa Polytechnica CTU Proceedings, 2022
We critically assess the performance of several variants of dual and dual-primal domain decomposition strategies in problems with fixed subdomain partitioning and high heterogeneity in stiffness coefficients typically arising in topology optimization of ...

Recent advances in domain decomposition methods for large-scale saddle point problems

open access: yesComptes Rendus. Mécanique, 2022
Scalability of parallel solvers for problems with high heterogeneities relies on adaptive coarse spaces built from generalized eigenvalue problems in the subdomains.

About Revisiting Domain Decomposition Methods for Poroelasticity

open access: yesMathematics, 2018
In this paper, we revisit well-established domain decomposition (DD) schemes to perform realistic simulations of coupled flow and poroelasticity problems on parallel computers.

A brief overview of non-overlapping domain decomposition methods

open access: yesGeofísica Internacional, 2011
Se presenta una visión general de los métodos de descomposición de dominio con dominios ajenos. Los métodos más eficientes que existen en la actualidad, el BDDC y el FETI–DP, se ubican en un marco 'primal' (el 'espacio de vectores derivados (DVS, por sus

A Recursive Variant of Schwarz Type Domain Decomposition Methods

open access: yesRatio Mathematica, 2016
In this paper a slightly different approach to the use of the domain decomposition method of the Schwarz type is proposed. Instead of the standard coarse space construction we propose to use a recursive solution on each domain.

Overlapping Domain Decomposition Methods with FreeFem++ [PDF]

open access: yes, 2014
International audienceIn this note, the performances of a framework for two-level overlapping domain decomposition methods are assessed. Numerical experiments are run on Curie, a Tier-0 system for PRACE, for two second order elliptic PDE with highly ...
