Simultaneous FETI and block FETI: Robust domain decomposition with multiple search directions
(Wiley, 2015)
Domain decomposition methods often exhibit very poor performance when applied to engineering problems with large heterogeneities. In particular, for heterogeneities along domain interfaces, the iterative techniques to solve ...
PARTITIONED ANALYSIS FOR DIMENSIONALLY-HETEROGENEOUS HYDRAULIC NETWORKS
(SIAM PUBLICATIONS, 2011)
In this work an iterative strategy is developed to tackle the problem of coupling dimensionally-heterogeneous models in the context of fluid mechanics. The procedure proposed here makes use of a reinterpretation of the ...
Wave-heat coupling in one-dimensional unbounded domains: artificial boundary conditions and an optimized Schwarz method
(Springer, 2022)
This paper deals with the coupling between one-dimensional heat and wave equations in unbounded subdomains, as a simplified prototype of fluid-structure interaction problems. First we apply appropriate artificial boundary ...
Black-box decomposition approach for computational hemodynamics: One-dimensional models
(ELSEVIER SCIENCE SA, 2011)
Increasing efforts exist in integrating different levels of detail in models of the cardiovascular system. For instance, one-dimensional representations are employed to model the systemic circulation. In this context, ...
Iterative strong coupling of dimensionally heterogeneous models
(JOHN WILEY & SONS LTD, 2010)
In this article we address decomposition strategies especially tailored to perform strong coupling of dimensionally heterogeneous models, under the hypothesis that one wants to solve each submodel separately and implement ...
Combining the DPG Method with Finite Elements
(2018)
We propose and analyze a discretization scheme that combines the discontinuous Petrov-Galerkin and finite element methods. The underlying model problem is of general diffusion-advection-reaction type on bounded domains, ...
Array analysis of the seismic wavefield of long-period events and volcanic tremor at Arenal volcano, Costa Rica
(2014-06-06)
We use wavefield decomposition methods (time domain cross correlation and frequency domain multiple-signal classification) to analyze seismic data recorded by a dense, small-aperture array located 2 km West of Arenal ...
Método de elementos finitos para la ecuación de Reacción-Difusión en medios heterogéneos
(2018)
Este trabajo estudia el calculo eficiente de soluciones para problemas de reacción-difusión en una y dos dimensiones con énfasis en medios heterogéneos. Para obtener aproximaciones numéricas usamos el método de elementos ...
