A Numerical 3D‐2D Coupling Strategy for Simulating Landslide‐Generated Tsunamis in Complex Geometries: The Taan Fiord, Alaska, Case Study

open access: yesJournal of Geophysical Research: Oceans, Volume 130, Issue 12, December 2025.
Abstract Landslide‐generated tsunamis represent a significant hazard, specifically in coastal, fjord, and lake environments. The accurate modeling of these complicated phenomena is crucial for risk assessment and preparation of mitigation strategies.

The Stratified Ocean Model With Adaptive Refinement (SOMARv2)

open access: yesJournal of Advances in Modeling Earth Systems, Volume 17, Issue 11, November 2025.
Abstract Numerical studies of submesoscale ocean dynamics are restricted by several challenges, including its vast range of scales, nonhydrostatic features, and strong anisotropy. The Stratified Ocean Model with Adaptive Refinement (SOMAR) was developed to address many of these issues.

Physics‐Informed Neural Networks for Solving the Two‐Dimensional Shallow Water Equations With Terrain Topography and Rainfall Source Terms

open access: yesWater Resources Research, Volume 61, Issue 9, September 2025.
Abstract Solving the two‐dimensional Shallow Water Equations (SWE) is a fundamental problem in flood simulation technology. In recent years, physics‐informed neural networks (PINNs) have emerged as a novel methodology for addressing this problem. Given their advantages in parallel computing, potential for data assimilation and parameter calibration ...

Generic Equations for Long Gravity Waves in Incompressible Fluid with Finite Amplitude [PDF]

open access: yesAppliedMath
We present the derivation of generic equations describing the long gravity waves in incompressible fluid with a decaying effect. We show that in this theory, the only restriction to the surface deviation is connected to the stability condition for the ...

A conservative numerical scheme for the multilayer shallow‐water equations on unstructured meshes

open access: yesQuarterly Journal of the Royal Meteorological Society, Volume 151, Issue 771, July 2025 Part B.
An energy‐conserving scheme is derived for the multilayer shallow water model, making use of the direct connection between energy conservation and the skew symmetry of the Poisson bracket for the model. A new mechanism is proposed to prevent layer interface outcropping.

Spontaneous Initiation and Evolution of Polygonal Fault Systems During the Early Burial of Sediments in 3D Numerical Models

open access: yesJournal of Geophysical Research: Solid Earth, Volume 130, Issue 7, July 2025.
Abstract Polygonal Fault Systems (PFS) or networks were generated in 3D finite‐difference models within the upper (active) layer of two‐layer model. The driving force of this process results from a progressive diagenetically induced volumetric contraction (porosity reduction) of the active layer during its burial.

Multiphysics Simulation Methods in Computer Graphics

open access: yesComputer Graphics Forum, Volume 44, Issue 2, May 2025.
Abstract Physics simulation is a cornerstone of many computer graphics applications, ranging from video games and virtual reality to visual effects and computational design. The number of techniques for physically‐based modeling and animation has thus skyrocketed over the past few decades, facilitating the simulation of a wide variety of materials and ...

Elliptical instability in hot Jupiter systems

open access: yes, 2013
Several studies have already considered the influence of tides on the evolution of systems composed of a star and a close-in companion to tentatively explain different observations such as the spin-up of some stars with hot Jupiters, the radius anomaly ...

An Exact Neumann‐to‐Dirichlet (NtD) Boundary Condition for Three‐Dimensional Wave Motion Over Piecewise Smooth Topographies Near a Vertical Breakwater

open access: yesEngineering Reports, Volume 7, Issue 4, April 2025.
Three‐dimensional field of wave elevation over a paraboloidal shoal near a wall. ABSTRACT This paper suggests an exact boundary condition, so‐called Neumann‐to‐Dirichlet (NtD) boundary condition for numerical analysis of the three‐dimensional wave motion over piecewise smooth topographies near a vertical breakwater.
