Error estimates of structure‐preserving Fourier pseudospectral methods for the fractional Schrödinger equation

Numerical Methods for Partial Differential Equations, 2019
AbstractThis paper gives a rigorous error analysis of the multisymplectic Fourier pseudospectral method for the nonlinear fractional Schrödinger equation. The method preserves some intrinsic structure properties including the generalized multisymplectic conservation law.

Incorporating directivity in the Fourier pseudospectral time-domain method using spherical harmonics

The Journal of the Acoustical Society of America, 2016
The pseudospectral time-domain method (PSTD) provides an efficient way to solve the linear acoustics equations. With regards to acoustic modeling and auralization, source directivity as well as head-related directivity have a clear influence on the perceived sound field and have to be included in computations.

Parallel calculations on the wind-driven oceanic circulation using Fourier pseudospectral methods

Proceedings of the 3rd international conference on Supercomputing - ICS '89, 1989
The shallow-water equations for the wind-driven oceanic circulation were solved in parallel, using Fourier pseudospectral methods. A domain decomposition approach was used to perform two-dimensional Fast Fourier Transforms (2-D FFTs), as part of a computational scheme for the parallel solution of the time dependent partial differential equations.The ...
