High‐resolution numerical simulations of electrophoresis using the Fourier pseudo‐spectral method

ELECTROPHORESIS, 2020
AbstractWe present the formulation, implementation, and performance evaluation of the Fourier pseudo‐spectral method for performing fast and accurate simulations of electrophoresis. We demonstrate the applicability of this method for simulating a wide variety of electrophoretic processes such as capillary zone electrophoresis, transient ...

The Fourier pseudo-spectral method for the SRLW equation

Applied Mathematics and Mechanics, 1989
In this paper we present a Fourier pseudo-spectral method with a restraint operator for the SRLW equation. We prove the stability of the schemes and give optimum error estimates.

Modeling infrasound propagation using the Fourier pseudo-spectral method.

The Journal of the Acoustical Society of America, 2011
As part of an undergoing effort to model infrasound propagation in the atmosphere, a pseudospectral time-domain method is employed to solve the linearized equations of thermo-viscous compressible gas dynamics in a two dimensional stratified atmosphere over a flat rigid ground surface.
