Course outline:

This is a course on selected topics on spectral methods for solving PDEs and on time discretization schemes for computational fluid dynamics and computational materials science, including:


Topics:

    PART I.
  • Some fundamental tools in numerical PDEs
  • Fourier-spectral methods
  • basic results for polynomial approximations
  • Galerkin and collocation methods for elliptic PDEs
  • Basic introduction to Fractional PDEs
  • Spectral methods using generalized Jacobi functions for fractional PDEs

    PART II.

  • Time discretization schemes for gradient flows
  • Time discretization schemes for Navier-Stokes equations
  • Phase-field models for multi-phase incompressible flows and their time discretization


Prerequisite: A good knowledge of calculus, linear algebra, numerical analysis and some basic programming skills are essential. Some knowledge of real analysis and functional analysis will be helpful but not necessary.


Requirement: There will be no exam. Course grades will be based on homework assignments and programming projects.
