Numerical Simulation of Pollutant Transport in Fractured Vuggy Porous Karstic Aquifers
Journal of Applied Mathematics, 2011 This paper begins with presenting a mathematical model for contaminant transport in the fractured vuggy porous media of a species of contaminant (PCP). Two phases are numerically simulated for a process of contaminant and clean water infiltrated in the ...

An Adaptive Multiscale Finite Element Method
, 2014 This work is devoted to an adaptive multiscale finite element method (MsFEM) for solving elliptic problems with rapidly oscillating coefficients. Starting from a general version of the MsFEM with oversampling, we derive an a posteriori estimate for the H-

Finite element heterogeneous multiscale method for the wave equation [PDF]
, 2010 A finite element heterogeneous multiscale method is proposed for the wave equation with highly oscillatory coefficients. It is based on a finite element discretization of an effective wave equation at the macro scale, whose a priori unknown effective ...

Advanced Functional Materials, EarlyView.A gradient‐engineered all‐paper sensor is fabricated by integrating MXene and in situ grown AgNPs within hierarchical cellulose networks. The device breaks the sensitivity–detection range trade‐off through cascaded conductive pathways, enabling ultrahigh pressure sensitivity, humidity–pressure decoupled dual‐mode sensing, and outstanding EMI shielding,

Bone‐Inspired Recyclable Composites for Damage‐Tolerant Circular Materials
Advanced Functional Materials, EarlyView.Bone‐inspired architected composites are developed by combining osteon‐like reinforcements with a recyclable Elium thermoplastic matrix. The hierarchical architecture redirects cracks and promotes energy dissipation, while enabling recovery of intact, aligned, load‐bearing reinforcement units that retain their original stiffness, revealing a route ...

Adjoint-Based Adaptive Convergence Control of the Iterative Finite Volume Multiscale Method
SPE Reservoir Simulation Conference, 2019 Abstract We propose a novel adaptive, adjoint-based, iterative multiscale finite volume (i-MSFV) method. The method aims to reduce the computational cost of the smoothing stage of the original i-MSFV method by selectively choosing fine-scale sub-domains (or sub-set of primary variables) to solve for.

International Journal for Multiscale Computational Engineering, 2022 This paper describes the development of a hierarchical multiscale procedure within the finite volume (FL) OpenFOAM framework for modeling the mechanical response of nonlinear heterogeneous solid materials. This is a first development of the hierarchical multiscale model for solid mechanics using the FL discretization method.
