Computational Fluid Dynamics
Presentation
As most flow problems exhibit turbulent nature and most engineering applications involve heat transfer, these two subjects will be covered. In addition, as many fluid flows are not steady-state phenomena, transient simulations and solution and relative issues like time step size will be discussed.

Industry case study
Nicolas Gourdain presents elsA for aerodynamics used by many by industrial partners such as Airbus, SAFRAN, etc. and AVBP for combustion, used by SAFRAN, IFP, etc.
The use of Computational Fluid Dynamics (CFD) is mandatory today both for scientific investigation of complex flows and industrial design of gas turbines and aircraft. Further improvement and optimization of such systems...

Presentation
An overview about mesh morphing and its benefits will be given with a specific focus on Radial Basis Functions (RBF) methods and the industrial tool RBF Morph, currently available as an add-on for the CFD solver ANSYS Fluent.
Standard applications of mesh morphing will be first explained; the tool is here used as an effective way to makes the original CFD model parametric with respect to...

The first session will cover basic exercises to set-up shape modifications on simple geometries (a cube immersed in a wind tunnel and a straight pipe). A step by step set-up will be demonstrated to gain confidence with the GUI of RBF Morph (set-up stage). An advanced session addressed to industrial meshes and complex set-up will follow. Pre computed set-up will be available so that the...

Hands-on training
The aim will be to test some of the requirements presented in the course (such as mesh-partitioning and load balancing) to achieve high-scalability on massively parallel computers (maybe also on GPUs).
Two examples are used to illustrate these concepts: a multi-block structured code (elsA) and an unstructured code (AVBP). Parallel computing strategies used with both flow solvers are...
