A Priori Error Bounds for the Approximate Deconvolution Leray Reduced Order Model

open access: yesNumerical Methods for Partial Differential Equations, Volume 41, Issue 6, November 2025.
ABSTRACT The approximate deconvolution Leray reduced order model (ADL‐ROM) uses spatial filtering to increase the ROM stability, and approximate deconvolution to increase the ROM accuracy. In the under‐resolved numerical simulation of convection‐dominated flows, ADL‐ROM was shown to be significantly more stable than the standard ROM and more accurate ...

Numerical Solution of the Convective and Diffusive Transport Problems in a Heterogeneous Porous Medium Using Finite Element Method [PDF]

open access: yesУчёные записки Казанского университета: Серия Физико-математические науки, 2016
The finite element approximation of the convective and diffusive transport equation has been considered. Different methods for stabilization of the finite element approximation have been discussed: upwind approximation of the convective term using ...

Finite Strain Robust Topology Optimization Considering Multiple Uncertainties

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 126, Issue 20, 30 October 2025.
ABSTRACT This paper presents a computational framework for the robust stiffness design of hyperelastic structures at finite deformations subject to various uncertain sources. In particular, the loading, material properties, and geometry uncertainties are incorporated within the topology optimization framework and are modeled by random vectors or random

Time-periodic solution for a fourth-order parabolic equation describing crystal surface growth

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2013
In this paper, by using the Galerkin method, the existence and uniqueness of time-periodic generalized solutions to a fourth-order parabolic equation describing crystal surface growth are proved.

Space‐Time Boundary Elements on Graded Meshes for 3D Elastodynamics

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 126, Issue 20, 30 October 2025.
ABSTRACT The solution to the elastodynamic equations in the exterior of a polygonal or polyhedral domain or a screen exhibits singularities at corners and edges. This paper presents a space‐time boundary element method in 3D on algebraically graded meshes to resolve these singularities, based on recently obtained error estimates for the weakly singular
