Numerical Methods for Flow Problems

Tutors: Daniel Arndt, Dörte Jando
Class data: LSF
Seminar: Mon 14-16h, Mathematikon (INF 205), Seminarraum 11, Start: April 24, 2017


The simulation of flow problems is of great importance in many applications, for example in the design process of new aircrafts or cars and simulations of air flow in the interior of buildings. Therefore, the analysis of numerical simulation methods is an important research field. Flow problems are often characterized by sattle point structures resulting from divergence constraints, by instationary phenomena and/or instabilities resulting from advection dominance. In this seminar we treat numerical methods to solve such problems using finite element methods.

Target group

Students of mathematics (BSc and MSc) as well as students of scientific computing (MSc).

Prior knowledge

Numerics for PDEs. Optionally: Numerical analysis of ordinary differential equations.


For participation in the seminar you have to register via Müsli (binding registration).

Additionally, please write us a mail with your subject of study, semester, BSc / MSc, ... . Please also mention related lectures you have already attended, courses you will take in the summer term. Generally, the seminar topic could already serve as preparation phase for your thesis.


The topics will be assigned starting from now. Interested students can prepare their presentations already in the semester break (we do recommend that). Latest assignment is in the beginning of the summer term. Generally, before presenting we recommend to discuss the structure of your talk with us.


The seminar covers the following topics:

  1. Sattle point problems in an abstract setting (inf sup stability, Stokes, suitable finite elements), literature
  2. IMEX for diffusion-advection problems?
  3. Splitting methods for time integration of flow problems (Guermond)
  4. Advection-diffusion problems and SUPG (Roos, Stynes, Tobiska)
  5. A posteriori error estimation for diffusion-dominant problems
  6. A posteriori error estimates for stabilized finite element methods (Tobiska, Verfuerth)

You are most invited to propose additional topics that fit into the area.
