PREFACE
Parallel CFD 2000, the twelfth in an international series of meetings featuring
computational fluid dynamics research on parallel computers, was held May 22-25, 2000 in
Trondheim, Norway, retuming to Europe for the first time since 1997. More than 125
participants from 22 countries converged for the conference which featured 9 invited lectures
and 70 contributed papers.
Following the trend of the past conferences, areas such as numerical schemes and
algorithms, tools and environments, load balancing, as well as interdisciplinary topics and
various kinds of industrial applications were all well represented in the work presented. In
addition, for the first time in the Parallel CFD conference series, the organizing committee
chose to draw special attention to certain subject areas by organizing a number of special
sessions. Particularly the special sessions devoted to affordable parallel computing, large eddy
simulation, and lattice Boltzmann methods attracted many participants.
We feel the emphasis of the papers presented at the conference reflect the direction of
the research within parallel CFD at the beginning of the new millennium. It seems to be a
clear tendency towards increased industrial exploitation of parallel CFD. Several presentations
also demonstrated how new insight is being achieved from complex simulations, and how
powerful parallel computers now make it possible to use CFD within a broader
interdisciplinary setting.
Obviously, successful application of parallel CFD still rests on the underlying
fundamental principles. Therefore, numerical algorithms, development tools, and
parallelization techniques are still as important as when parallel CFD was in is infancy.
Furthermore, the novel concepts of affordable parallel computing as well as metacomputing
show that exciting developments are still taking place.
As is often pointed out however, the real power of parallel CFD comes from the
combination of all the disciplines involved: Physics, mathematics, and computer science. This
is probably one of the principal reasons for the continued popularity of the Parallel CFD
Conferences series, as well as the inspiration behind much of the excellent work carried out
on the subject. We hope that the papers in this book, both on an individual basis and as a
whole, will contribute to that inspiration.
