For the eigenvalue of a two‐dimensional hollow waveguide, a regularized MFS‐ES (RMFS‐ES) is proposed, which avoids the choice of the auxiliary boundary and spurious frequencies. In addition, to improve the accuracy of RMFS‐ES in solving polygonal waveguide eigenvalue, a wedge scheme (WS) is given.

Regularized SPH model for soil–structure interaction with generalized frictional boundary
Abstract This paper proposes a regularized smoothed particle hydrodynamics (SPH) scheme to solve the problems of tensile instability and stress noise in large‐deformation soil–structure interaction. Particle shifting and stress regularization are combined to maintain uniform stresses and particle distributions.

ABSTRACT In this paper, we propose a decompositional (phase‐wise split) approach to solve a two‐dimensional, two‐phase (solid and liquid, say), nonlinear inverse Stefan problem. The first step is to approximate the unknown moving boundary between the two phases and the Stefan condition on that boundary using the overspecified boundary and initial data ...

A review of multiscale numerical modeling of rock mechanics and rock engineering
Multiscale numerical methods of rock mechanics and rock engineering are reviewed, and the review results show that more attention should be paid to the development of an advanced constitutive model in addition to numerical techniques themselves. Abstract Rock is geometrically and mechanically multiscale in nature, and the traditional phenomenological ...

Latent Representation Learning in Physics‐Informed Neural Networks for Full Waveform Inversion
Abstract Full waveform inversion (FWI), a state‐of‐the‐art seismic inversion algorithm, comprises an iterative data‐fitting process to recover high‐resolution Earth's properties (e.g., velocity). At the heart of this process lies the numerical wave equation solver, which necessitates discretization.

ANN‐Based Green's Function Approach for Reservoir Geomechanics
ABSTRACT Green's functions have been a tool to analyze important reservoir geomechanics effects like subsidence, compaction, well closure, and permeability variation. However, the classical Green's function is related to linear elastic, homogenous, and geometrically simplified media.

Multiphysics Simulation Methods in Computer Graphics
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 ...

Risk analysis of distribution network outages under a typhoon–rainstorm–flood disaster chain
Abstract The typhoon–rainstorm–flood disaster chain poses a significant flooding risk to urban distribution network (DN) equipment, often leading to power system outages. The increasing frequency and severity of this disaster chain in East Asia, driven by global warming, population growth, and land‐use changes, highlight the need for improved disaster ...
