Preface

The idea of this book was born during the Conference on Modelling Fluid

Flow held in Budapest at the beginning of September 2006. During this oc-

casion, we had decided to propose and thus hold a workshop entitled Cou-

pling CFD with Optimisation, based on our rapidly increasing experience

with this highly interesting topic. We were nevertheless surprised to see the

resonating enthusiasm displayed throughout the workshop by the conference

participants.

From the discussions with all the speakers present at this workshop as well

as the survey of the scope of the available books and review articles on this

subject, it became easier to understand this great interest. While there is a

wealth of new research projects that deal with the coupling of Computational

Fluid Dynamics (CFD) and modern Optimization techniques, it is however

di cult to nd reference publications on this topic. There are indeed a few,

excellent books available (see also the Introduction), but they are mostly

restricted to aerodynamics, since this has been the rst eld of CFD for

which optimization has become a tool of major importance. Moreover, the

connection between CFD and Evolutionary Algorithms, often required when

considering more complex systems of equations and physical models, has not

been documented extensively.

Therefore we decided, together with the support of almost all workshop

participants and a few internationally renowned newcomers, to gather and re-

count our experience concerning Optimization based on evaluations obtained

through Computational Fluid Dynamics (a procedure abbreviated in this

book as CFD-O ), in order to prepare a book covering most of the relevant

aspects and issues. Thanks to the hard work and constant support of all con-

tributors, it has been nally possible to release this publication almost exactly

one year after the workshop in Budapest. We hope that the interested readers

will nd here appropriate answers to the main questions: What is indeed

CFD-O? What simulation is today possible using CFD-O? How can I rely on

CFD-O for my own applications and which approach should I choose?

Preface

Our rst research project on CFD-O was connected with the Ph.D. super-

vision of Mr. R. Baron at the Ecole Centrale in Paris. He is the creator of our

Optimization library (Opal) and must be thanked here for the quality of his

work and for his unsurpassed motivation. The authors would furthermore like

to thank Ms. Imelda Pasley for her thorough corrections of the manuscript.

The quality of many graphical illustrations has been greatly enhanced by

Mr. Imre Ferencsin.
