Free Bars in Straight Channels: Pattern Formation far Beyond Criticality
Journal of Geophysical Research: Earth Surface, Volume 131, Issue 7, July 2026.Abstract Bar formation plays a central role in river morphodynamics and has been extensively studied by means of analytical theories, flume experiments and numerical simulations. In this study, we investigate strongly nonlinear mode competition and free bar dynamics using a spectral numerical model. Starting from near‐flat random bed initial conditions,

Numerical solution for one-dimensional pure-convection problems using the high-order Taylor-Galerkin element-free method [PDF]
مهندسی عمران شریفThe present study proposes a novel approach for solving one-dimensional pure convection problems, utilizing a high-order Taylor Galerkin element-free method. The standard Galerkin method has limitations in solving such problems due to the predominance of

Leaky Sewers Hydraulically Disconnect from Groundwater: A Proof‐of‐Concept
Groundwater, Volume 64, Issue 4, Page 483-497, July/August 2026.In this study, we newly demonstrate that leaky pipes can become hydraulically disconnected from the underlying groundwater—a phenomenon analogous to river–groundwater interactions. Through numerical modeling, we show that, as the groundwater table declines, the leakage flux from the pipe (in absolute terms) initially increases until a critical depth ...

Comparison of high-order methods on unstructured grids [PDF]
, 2013 A high-order Discontinuous Galerkin (DG) method is formulated and implemented on the Cranfield University’s 3D unstructured Finite Volume Method (FVM) code (UCNS3D), for both linear and non-linear hyperbolic conservation laws and for test-cases which ...

International Journal for Numerical Methods in Engineering, Volume 127, Issue 12, 30 June 2026.ABSTRACT Limit analysis and yield design provide a well‐defined mathematical framework for upscaling the strength properties of heterogeneous materials. These techniques can be incorporated into an FFT‐based computational micromechanics framework to evaluate the strength of heterogeneous materials, based on images of their microstructure.

Discontinuous Galerkin Computation of the Maxwell Eigenvalues on Simplicial Meshes [PDF]
, 2005 This paper is concerned with the discontinuous Galerkin approximation of the Maxwell eigenproblem. After reviewing the theory developed in [5], we present a set of numerical experiments which both validate the theory, and provide further insight ...

A Cartesian-grid integrated-RBF Galerkin technique [PDF]
, 2010 This paper describes a high-order Galerkin technique, which is based on indirect/integrated radial-basis-function networks (IRBFNs) and Cartesian grids, for the discretisation of elliptic problems in two dimensions.
