SCALABILITY ANALYSIS OF PARALLEL GMRES IMPLEMENTATIONS [PDF]

open access: yesParallel Algorithms and Applications, 2002
Abstract Applications involving large sparse nonsymmetric linear systems encourage parallel implementations of robust iterative solution methods, such as GMRES(k). Two parallel versions of GMRES(k) based on different data distributions and using Householder reflections in the orthogonalization phase are analyzed with respect to scalability (their ...

Computational analysis to assess hemodynamic forces in descending thoracic aortic aneurysms

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Left: Pre‐processing. First, we perform the segmentation of the Computer Tomography angiorgraphy (angio‐CT) scans of a healthy patient, obtaining the surface of a healthy thoracic aorta with a Type III aortic arch. Then, we build nine ideal configurations with Descending Thoracic Aortic Aneurysm (DTAA), varying the aortic arch ...

A Modified GMRES Method for Solving a Symmetric Solution to Lyapunov Equation for Multi-Agent Systems

open access: yesSICE Journal of Control, Measurement, and System Integration, 2019
We consider solving a large-scale Lyapunov equation for a multi-agent system. As is well known, the Lyapunov equation can be solved by equivalently rewriting it as a system of linear equations.

An Electric Field Volume Integral Equation Approach to Simulate Surface Plasmon Polaritons

open access: yesAdvanced Electromagnetics, 2013
In this paper we present an electric field volume integral equation approach to simulate surface plasmon propagation along metal/dielectric interfaces. Metallic objects embedded in homogeneous dielectric media are considered.

Structure–Property Relationships of Solid Oxide Fuel Cell Electrodes Using Real and Reconstructed Microstructures

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 126, Issue 24, 30 December 2025.
ABSTRACT Solid oxide fuel cells (SOFCs) are a promising technology for producing clean energy in the future. To enhance the efficiency and the lifetime of SOFCs and SOFC stacks, novel materials and innovative material compositions for the constituent layers—namely the cathode, anode, and electrolyte—must be developed.

Infinite GMRES for Parameterized Linear Systems

open access: yesSIAM Journal on Matrix Analysis and Applications, 2022
We consider linear parameter-dependent systems $A(μ) x(μ) = b$ for many different $μ$, where $A$ is large and sparse, and depends nonlinearly on $μ$. Solving such systems individually for each $μ$ would require great computational effort. In this work we propose to compute a partial parameterization $\tilde{x} \approx x(μ)$ where $\tilde{x}(μ)$ is ...

Coupling Models of Resistive Valves to Muscle Mechanics in Cardiac Fluid–Structure Interaction Simulations

open access: yesInternational Journal for Numerical Methods in Biomedical Engineering, Volume 41, Issue 12, December 2025.
Scheme of the cardiac fluid‐structure interaction model including valve‐wall interaction. ABSTRACT To accurately simulate all phases of the cardiac cycle, computational models of hemodynamics in heart chambers need to include a sufficiently faithful model of cardiac valves.

Multilevel acceleration of scattering-source iterations with application to electron transport

open access: yesNuclear Engineering and Technology, 2017
Acceleration/preconditioning strategies available in the SCEPTRE radiation transport code are described. A flexible transport synthetic acceleration (TSA) algorithm that uses a low-order discrete-ordinates (SN) or spherical-harmonics (PN) solve to ...
