Sharp quadrature error bounds for the nearest-neighbor discretization of the regularized stokeslet boundary integral equation [PDF]
, 2018 The method of regularized stokeslets is a powerful numerical method to solve the Stokes flow equations for problems in biological fluid mechanics. A recent variation of this method incorporates a nearest-neighbor discretization to improve accuracy and ...

Regularized SPH model for soil–structure interaction with generalized frictional boundary
International Journal for Numerical and Analytical Methods in Geomechanics, Volume 47, Issue 10, Page 1852-1875, July 2023., 2023 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.

Water Resources Research, Volume 59, Issue 6, June 2023., 2023 Abstract Accurate modeling of water flow and solute transport in unsaturated soils is of significant importance for precision agriculture, environmental protection and aquifer management. Traditional modeling approaches are considerably challenging since they require well‐defined boundaries and initial conditions.

Sensitivity and Calibration of Three‐Dimensional SPH Formulations in Large‐Scale Landslide Modeling
Journal of Geophysical Research: Solid Earth, Volume 128, Issue 2, February 2023., 2023 Abstract Numerical prediction of landslide runout and deposition is important for estimating landslide risk and developing mitigation plans. The choice of a suitable model and its parameters and a confident calibration strategy are crucial for numerical simulations.
