OpenOLAT: Optimization in Fluid Mechanics

Audience:

Master students in mathematics and computer science. Preferably with some basic knowledge about PDEs and numerics.

Objective:

We will introduce and investigate methods for efficient numerical solutions to shape optimization problems in fluid mechanics and questions in optimal active flow control.
In the tutorial classes we will apply such methods to an airfoil design problem within the open-source solver SU2.
