This hands-on course Aerodynamics and Parallel Computing
is held in the frame of the New Codes Workshop
(Maitrise des Codes Industriels et ParallÚlisme - MCIP) in the winter term at
ENSEEIHT Engineering School which
belongs to the Institut National Polytechnique de Toulouse. The course is
optional for final year master students in 'Option MFN -
Mécanique de Fluides Numérique' (Computational Fluid Dynamics =
CFD in english). The entire course is composed of
6 sessions and was held for the first time in 1996/1997 under the former
label of "BES AVBP".
The course aims to apply fundamental issues of CFD like boundary conditions or numerical schemes (as taught in the first semester) in the frame of a industrial flow solver. For this, the parallel flow solver AVBP of CERFACS is utilized, which solves the compressible Navier-Stokes equations on unstructured grids.
In the first session of this course a brief introduction to the AVBP code and the pre- and postprocessing tools is given. A first computation on the standard, well-documentated test case "channel with bump" (see figure below) is carried out in order to familiarize the students with AVBP. The main part of the course (sessions 2 to 5) is devoted to a little project which is selected by the students from a list of proposed topics (see below). These projects deal with various aspects of CFD such as mesh generation, setting up of boundary conditions, etc., the execution of the flow solver and the visualization and interpretation of results. The commercial mesh generator PreBFC/Tgrid of Fluent Inc. is used for grid generation. Given the time restrictions and limited computational resources only two-dimensional configurations are proposed. All computations are carried out on the cluster of workstations at N7, with exception of the task on parallel computing, which is executed on Silicon Graphics local memory computers such as the SGI PowerChallenge of CERFACS or the SGI Origin2000 at CICT. The last session is devoted to an oral exam. A brief report which summarizes the results obtained has to be provided. A 35-page document on this hands-on course along with technical documentation describing the various software tools is made available at the beginning of the course.
