The lab course gives an application oriented introduction to the following topics in computational fluid dynamics (lecturers may select certain deepening aspects):

  • Modelling of fluid flow via the Navier-Stokes equations
  • Finite-Difference methods for spatial discretisation of the partial differential equations
  • Semi-implicit time-stepping methods for incompressible flow
  • Iterative solvers for the pressure Poisson equation
  • Domain decomposition and parallelisation
  • Treatment of boundary conditions and obstacles in the flow
  • Free surface flows
  • Integration of transport equations
  • Visualisation techniques for fluid dynamics: particle tracing, streamlines and streaklines

The programming language will be C++.

The lectures accompanying this lab course will be conducted in English. The assignments will also be given in English. Completed assignments will be presented by the students in English or German.

Project phase

Note: The deadline of the project (on July 21, see above) is combined with a review session on the same day (similar to the review sessions of the worksheets 1 - 3). This review session is also COMPULSORY!

The final classroom session on July 24 is going to be postponed! The new schedule will be anounced as soon as possible on this webpage!

See the timeline above for the new date of the final session!
