Short courses
- Stationary Methods for Multiphysics Problems (with H. Tchelepi), 2021 CRM Summer School: Solving large systems efficiently in multiphysics numerical simulations, online, May 31-June 10, 2021
Course Description: A six-hour mini-course (4 x 1.5
hours, fourth lecture given by H. Tchelepi) on iterative methods and
multiphysics: examples of multiphysics problems, phase field and
domain decomposition. Fixed point methods: Newton's method,
stationary iterative methods for linear problems. Krylov methods and
the conjugate gradient method: derivation and convergence,
preconditioning.
- Introductory Domain Decomposition Short Course (with L. Halpern and M.J. Gander), 25th International Conference on Domain Decomposition Methods, St. John's, Newfoundland and Laborador, Canada, July 22, 2018
Course Description: A one-day introductory course on
basic domain decomposition methods, consisting of three one-hour
lectures on theoretical aspects in the morning and a three-hour
practial session in the afternoon. The morning sessions consist of
lectures on Schwarz methods, Dirichlet-Neumann and Neumann-Neumann
methods, and on modern coarse spaces. During the aftenroon session,
participants experiment with the above methods using sample Matlab codes.
- Dirichlet-Neumann and Neumann-Neumann methods, Summer School on Domain Decomposition Methods à Nice 2018, Université Côte d'Azur, France, June 19-21, 2018
Course Description: A 1.5-hour lecture and a 2-hour
practical session (with G. Ciaramella) during a three-day short
course on domain decomposition methods. In the lecture portion, we
introduce the Dirichlet-Neumann (DN) and Neumann-Neumann (NN)
methods, which are naturally formulated on non-overlapping domain
decompositions. We discuss their convergence behaviour on two
subdomains, first in 1D, then in 2D using Fourier techniques seen in
Lecture 1. The influence of geometry and relaxation parameters will
be discussed, and we explain how these methods can be extended to
yield FETI and BDDC methods, which are very powerful methods that
can be used for problems with complicated geometries.

Course Description: A 5-hour mini-course on numerical methods for spectral theory: finite difference and finite element methods for PDE eigenvalue problems, algorithms
