Cutoff wavenumber analysis of arbitrarily shaped waveguides using regularized method of fundamental solutions with excitation sources

open access: yesElectronics Letters, 2023
The method of fundamental solutions with excitation source (MFS‐ES) is a reliable method for determining the eigenvalues of a two‐dimensional hollow waveguide. However, the accuracy in MFS‐ES is extremely dependent on the choice of the auxiliary boundary.

Hybrid finite difference/finite element immersed boundary method. [PDF]

open access: yesInt J Numer Method Biomed Eng, 2017
The immersed boundary method is an approach to fluid-structure interaction that uses a Lagrangian description of the structural deformations, stresses, and forces along with an Eulerian description of the momentum, viscosity, and incompressibility of ...

Passively parallel regularized stokeslets. [PDF]

open access: yesPhilos Trans A Math Phys Eng Sci, 2020
Stokes flow, discussed by G.G. Stokes in 1851, describes many microscopic biological flow phenomena, including cilia-driven transport and flagellar motility; the need to quantify and understand these flows has motivated decades of mathematical and ...

Simultaneous numerical determination of a corroded boundary and its admittance [PDF]

open access: yes, 2014
In this paper, an inverse geometric problem for Laplace’s equation arising in boundary corrosion detection is considered. This problem, which consists of determining an unknown corroded portion of the boundary of a bounded domain and its admittance Robin

GIZMO: A New Class of Accurate, Mesh-Free Hydrodynamic Simulation Methods [PDF]

open access: yes, 2015
We present two new Lagrangian methods for hydrodynamics, in a systematic comparison with moving-mesh, SPH, and stationary (non-moving) grid methods. The new methods are designed to simultaneously capture advantages of both smoothed-particle hydrodynamics

2.5D singular boundary method for exterior acoustic radiation and scattering problems [PDF]

open access: yes, 2022
In this paper, a numerical methodology based on a two-and-a-half-dimensional (2.5D) singular boundary method (SBM) to deal with acoustic radiation and scattering problems in the context of longitudinally invariant structures is proposed and studied.
