Advanced Computation in Fluid Mechanics (DD2365), 7.5hp, Spring 2016

Advanced Computation in Fluid Mechanics The course focuses on four topics:

* FEM for incompressible flow.
* FEM for the time-dependent Navier-Stokes equations.
* Error estimation and adaptive methods for the Navier-Stokes equations.
* Computational methods for turbulent flow.
Recommended prerequisites SF2561 The Finite Element Method

Course activities
* 4 lectures/labs
* 3 project seminars
Course goals The goal of the course is to present efficient computational methods for fluid mechanics simulations, with focus on adaptive finite element methods (FEM) for incompressible flow, and to train the student to apply these computational methods to address fluid mechanics problems. Research challenges in the field are highlighted, e.g. with respect to simulation of turbulent flow.

After completion of the course the student will be able to:

* Formulate an adaptive FEM method for the Navier-Stokes equations.
* Carry out a basic stability ananysis of a FEM method for the Navier-Stokes equations.
* Carry out a basic a posteriori error analysis of a FEM method for the Navier-Stokes equations.
* Implement an adaptive FEM method for the Navier-Stokes equations in a FEM software.
* Account for the characteristics of different computational methods for turbulent flow.
Examination
* Project report and presentation
* Written exam based on lectures, labs and project
