An Eulerian Finite Element Method for PDEs in time-dependent domains

, 2018
The paper introduces a new finite element numerical method for the solution of partial differential equations on evolving domains. The approach uses a completely Eulerian description of the domain motion. The physical domain is embedded in a triangulated

Artificial neural network-enhanced unconditionally stable finite-difference time-domain technique for multiscale problems

Scientific African
Electromagnetic sensing and system-level design challenges are often multiscale in nature, making them difficult to solve. These challenges will likely continue to hinder system-level sensing and design optimization for the foreseeable future. Typically,

Finite Difference Time Domain Method For Grating Structures

, 2012
International audienceThe aim of this chapter is to present the principle of the FDTD method when applied to the resolution of Maxwell equations. Centered finite differences are used to approximate the value of both time and space derivatives that appear

On the Equivalence of the Digital Waveguide and Finite Difference Time Domain Schemes

, 2004
It is known that the digital waveguide (DW) method for solving the wave equation numerically on a grid can be manipulated into the form of the standard finite-difference time-domain (FDTD) method (also known as the ``leapfrog'' recursion).

A stable finite difference scheme for fractional viscoelastic wave propagation in space-time domain

Journal of Numerical Analysis and Approximation Theory
This work focuses on the numerical approximation of the one dimensional wave propagation equation in a viscoelastic medium modelled by the fractional Zener model. First, we propose an explicit centred finite difference scheme.

Finite difference time domain calculation of transients in antennas with nonlinear loads [PDF]

In this paper transient fields for antennas with more general geometries are calculated directly using Finite Difference Time Domain methods. In each FDTD cell which contains a nonlinear load, a nonlinear equation is solved at each time step.
