CME358: The Finite Element Method for Fluid Mechanics
Course Outline
Introduction
- Incompressible fluid mechanics.
- Reminder on finite element in the coercive frameworks (Lax-
Milgram, Sobolev spaces, Lagrangian finite elements).
- Why the coercive framework is not sufficient in many
applications.
Theory for mixed problems
- Continuous case, inf-sup condition.
- Application to Stokes problem.
- Link with optimization under constraints. Saddle point problems.
Stable finite elements for mixed problems
- Convergence analysis.
- Algebraic aspects. Uzawa algorithm. Conditioning.
Stable finite elements for mixed problems
- Fortin lemma. Analysis of P1-bubble-P1 finite element.
- Other examples of finite elements.
- Other examples of finite elements.
Stabilized finite element
- The advection diffusion case.
Introduction to Navier-Stokes: projection algorithms
