A Level Set Method on Particle Flow Maps

International Journal for Numerical Methods in Engineering, Volume 127, Issue 20, 30 October 2026.
ABSTRACT Accurate interface tracking is central to numerical simulations involving moving boundaries, including multiphase flows, free‐surface dynamics, phase‐change problems, and other interface‐driven processes in computational mechanics. Although, level set methods provide a flexible implicit representation of evolving interfaces, their grid‐based ...

Elimination of Spurious Modes in Reduced‐Order‐Modeling‐Based Topology Optimization of Geometrically Nonlinear Structures

International Journal for Numerical Methods in Engineering, Volume 127, Issue 20, 30 October 2026.
ABSTRACT In geometrically nonlinear topology optimization, elements with low pseudo‐densities, subjected to compression from neighboring stiffer regions, can lead to complications, such as “inside‐out” elements in 2D structures or spurious local buckling in shells and plates.

Direct Experimental Observation of Wave‐Amplified Turbulent Mixing

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Langmuir turbulence is a key mechanism to enhanced mixing in the upper ocean. Although often associated with wind, the theoretical framework proposed by Craik and Leibovich requires only vorticity and wave‐induced Stokes drift, regardless of their cause.

Hessian geometry and Frobenius manifolds with curvature

A Riemannian metric is called Hessian if, locally, it can be written as the Hessian of a function called the Hessian potential. A (flat) Manin-Frobenius manifold is a flat Riemannian manifold furnished with a commutative and associative product compatible with the metric, such that a certain potentiality property is satisfied.

A Unified Block‐Modal Framework for Inverse Source Problems in Heat and Mass Transfer

International Journal for Numerical Methods in Engineering, Volume 127, Issue 19, 15 October 2026.
ABSTRACT This work presents a unified block–modal framework for inverse source identification in linear diffusive problems arising in heat and mass transfer. Starting from a general parabolic model with mixed boundary operators, the Classical Integral Transform Technique is employed to project the dynamics onto an orthonormal eigenbasis, yielding a ...
