Second‐Order Computational Homogenization of Nonlinear Fluid Flow Through Porous Media

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 127, Issue 1, 15 January 2026.
ABSTRACT We present a second‐order computational multiscale model for heterogeneous porous media, which allows for the scale bridging of transient fluid‐flow processes through porous materials with non‐separated scales. The formulation connects a homogenized macroscopic scale described by a local theory of grade two with heterogeneous microstructures ...

Adaptive Virtual Element Method of Material‐Field Series Expansion Topology Optimization and Its Application in Metamaterials

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 127, Issue 1, 15 January 2026.
ABSTRACT This paper proposes a novel adaptive topology optimization framework that integrates the Virtual Element Method (VEM) with the Material‐Field Series Expansion (MFSE). Within the VEM‐MFSE framework, we propose a material gradient‐driven adaptive strategy, in which elements are refined in regions with higher material density gradients as the ...
