This module teaches the principals of Fourier spectral methods, their utility in solving partial differential equation and how to implement them in code. Performance considerations for several Fourier spectral implementations are discussed and methods for effective scaling on parallel computers are explained.

Upon completion of this module students should be able to understand finite precision arithmetic and how it relates to the accuracy of numerical calculations, solve ordinary differential equations and partial differential equations using separation of variables, use numerical time-stepping methods to solve ordinary and partial differential equations, use pseudo spectral methods like Fourier Transform and Fast Fourier Transform to solve partial differential equations, and use these methods to solve partial differential equations in a serial setting and a parallel setting using Matlab and Fortran.
