Simulation of Metasurfaces in Finite Difference Techniques [PDF]

open access: yesIEEE Transactions on Antennas and Propagation, 2016
We introduce a rigorous and simple method for analyzing metasurfaces, modeled as zero-thickness electromagnetic sheets, in finite difference (FD) techniques.

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

open access: yesInternational Journal for Numerical Methods in Biomedical Engineering, 2016
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 the

A Nodal Immersed Finite Element-Finite Difference Method. [PDF]

open access: yesJ Comput Phys, 2023
The immersed finite element-finite difference (IFED) method is a computational approach to modeling interactions between a fluid and an immersed structure. This method uses a finite element (FE) method to approximate the stresses and forces on a structural mesh and a finite difference (FD) method to approximate the momentum of the entire fluid ...

Finite difference magnetoelastic simulator. [PDF]

open access: yesOpen Res Eur, 2021
We describe an extension of the micromagnetic finite difference simulation software MuMax3 to solve elasto-magneto-dynamical problems. The new module allows for numerical simulations of magnetization and displacement dynamics in magnetostrictive materials and structures, including both direct and inverse magnetostriction.

Finite-Difference Operators for 2D problems [PDF]

open access: yesBulletin of the Polish Academy of Sciences: Technical Sciences, 2020
This paper presents the concept of using algorithms for reducing the dimensions of finite-difference equations of two-dimensional (2D) problems, for second-order partial differential equations.

Multiplicative finite difference methods [PDF]

open access: yesQuarterly of Applied Mathematics, 2009
Based on multiplicative calculus, the finite difference schemes for the numerical solution of multiplicative differential equations and Volterra differential equations are presented. Sample problems were solved using these new approaches.

Fractional discrete-continuous model of heat transfer process [PDF]

open access: yesArchives of Control Sciences, 2021
The paper proposes a new, state space, finite dimensional, fractional order model of a heat transfer in one dimensional body. The time derivative is described by Caputo operator.

Finite difference schemes with monotone operators

open access: yesAdvances in Difference Equations, 2004
Several existence theorems are given for some second-order difference equations associated with maximal monotone operators in Hilbert spaces. Boundary conditions of monotone type are attached.

A parameter uniform method for two-parameter singularly perturbed boundary value problems with discontinuous data

open access: yesMethodsX, 2023
We consider two-parameter singularly perturbed problems of reaction-convection-diffusion type in one dimension. The convection coefficient and source term are discontinuous at a point in the domain.
