A Randomized Q-OR Krylov Subspace Method for Solving Nonsymmetric Linear Systems

Mathematics
The most popular iterative methods for solving nonsymmetric linear systems are Krylov methods. Recently, an optimal Quasi-ORthogonal (Q-OR) method was introduced, which yields the same residual norms as the Generalized Minimum Residual (GMRES) method ...

Comparison of different iterative schemes for ISPH based on Rankine source solution

International Journal of Naval Architecture and Ocean Engineering, 2017
Smoothed Particle Hydrodynamics (SPH) method has a good adaptability for the simulation of free surface flow problems. There are two forms of SPH. One is weak compressible SPH and the other one is incompressible SPH (ISPH).

On numerical solution of nonlinear parabolic multicomponent diffusion-reaction problems

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2021
This work continues our previous analysis concerning the numerical solution of the multi-component mass transfer equations. The present test problems are two-dimensional, parabolic, non-linear, diffusion- reaction equations. An implicit finite difference

Nonlinear Receding‐Horizon Differential Game for Drone Racing Along a Three‐Dimensional Path

International Journal of Robust and Nonlinear Control, Volume 36, Issue 15, Page 7177-7192, October 2026.
ABSTRACT Drone racing requires high‐speed navigation through three‐dimensional paths, posing significant challenges in control engineering. Existing control methods lack a feedback control framework that simultaneously addresses nonlinear drone dynamics and multi‐agent competitive interactions, such as overtaking or obstructing opponents.

Método GMRES(m) pré-condicionado com a estrutura de dados CSR

Cadernos Cajuína
Tem-se que os métodos iterativos são mais eficientes que os métodos diretos na resolução de sistemas lineares e esparsos. Saad e Schultz (1986) propuseram o método GMRES reinicializado que é alvo de muitas pesquisas.

Perched groundwater simulation using the picard iteration‐based always active cell method

River, Volume 5, Issue 3, Page 453-464, August 2026.
Abstract Aquitards within the vadose zone impede vertical infiltration, leading to the formation of saturated perched groundwater. Perched groundwater flows laterally along aquitards, resulting in a heterogeneous spatial distribution of groundwater recharge that significantly influences groundwater formation and evolution.

The Upper Bound for GMRES on Normal Tridiagonal Toeplitz Linear System

Journal of Mathematical Extension, 2015
The Generalized Minimal Residual method (GMRES) is often used to solve a large and sparse system Ax = b. This paper establishes error bound for residuals of GMRES on solving an N × N normal tridiagonal Toeplitz linear system.

Three‐Dimensional Optical and Computational Reconstruction of Colloidal Electrokinetic Flows via Multiplane Imaging and Multiscale Modeling

Small, Volume 22, Issue 58, 16 October 2026.
Fast 3D multiplane microscopy is combined with multiscale electrokinetic modeling to reconstruct nanoparticle motion around quadrupolar electrodes. This integrated optical‐computational framework reveals the full three‐dimensional structure of colloidal electrokinetic flows, including localized trapping, depletion layers, and complex vortical motion ...

Scalable Phase‐Field Implementation of Crack Evolution (SPICE) for Modeling Surface Crevasse Growth and Interaction in Glaciers

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 10, October 2026.
Abstract Iceberg calving driven by crevasse propagation is an important source of ice loss from the Greenland and Antarctic ice sheets. However, simulating crevasse growth and interaction in 3D, spanning meters to kilometers length scales, remains computationally challenging for high‐fidelity models based on nonlocal continuum damage mechanics and ...

Convergence Acceleration Techniques for Steady Flow Simulations Using High-Order Finite Volume on Unstructured Grid

气体物理
Although high-order unstructured grid finite volume methods based on variational reconstruction offer advantages like high accuracy and computational efficiency, their iterative convergence robustness and speed significantly lag behind second-order ...
