Subject: Four New Books on CFD, PDE and CAS

Lecture Notes in Computational Science and Engineering Vol. 16: J. Lang
"Adaptive Multilevel Solution on Nonlinear Parabolic PDE Systems - Theory,
Algorithm and Applications"
2000. DM 129,00; Softcover ISBN 3-540-67900-6

This book deals with the adaptive numerical solution of parabolic partial
differential equations (PDEs) arising in many branches of applications. It
illustrates the interlocking of numerical analysis, the design of an
algorithm and the solution of practical problems. In particular, a
combination of Rosenbrock-type one-step methods and multilevel finite
elements is analysed. Implementation and efficiency issues are discussed.
Special emphasis is put on the solution of real-life applications that arise
in today' s chemical industry, semiconductor-device fabrication and heath
care. The book is intended for graduate students and researchers who are
either interested in the theoretical understanding of instationary PDE
solvers or who want to develop computer codes for solving complex PDEs.

Springer Series in Computational Mathematics Vol. 29: P. Wesseling
"Principles of Computational Fluid Dynamics"
2000. DM 169,00; Hardcover ISBN 3-540-67853-0

The book is aimed at graduate students, researchers, engineers and
physicists involved in fluid computations. An up-to-date account is given of
the present state-of-the-art of numerical methods employed in computational
fluid dynamics. The underlying numerical principles are treated with a fair
amount of detail, using elementary methods. Attention is given to the
difficulties arising from geometric complexity of the flow domain. Uniform
accuracy for singular perturbation problems is studied, pointing the way to
accurate computation of flows at high Reynolds number. Unified methods for
compressible and incompressible flows are discussed. A treatment of the
shallow-water equations is included. A basic introduction is given to
efficient iterative solution methods. Many pointers are given to the current
literature, facilitating further study.

Scientific Computing - CASC 2000"
2000. DM 189,00; Hardcover ISBN 3-540-41040-6

The book covers various topics of computer algebra methods, algorithms and
software applied to scientific computing. One of the important topics of the
book is the application of computer algebra methods for the development of
new efficient analytic and numerical solvers, both for ordinary and partial
differential equations. A specific feature of the book is a detailed
analysis of the advanced software systems like Mathematica, Maple etc. from
the viewpoint of their applicability for the solution of scientific
computing problems. The book will be useful for researchers and engineers
who apply the advanced computer algebra methods for the solution of their

J. Malek, J. Necas, M. Rokyta (Eds.) " Advances in Mathematical Fluid
Mechanics - Lecture Notes of the Sixth International School "Mathematical
Theory in Fluid Mechanics", Paseky, Czech Republic, Sept. 19-25, 1999

This book consists of six survey contributions, focusing on several open
problems of theoretical fluid mechanics both for incompressible and
compressible fluids. The following topics are studied intensively within the
book: global in time qualitative properties of solutions to compressible
fluid models; fluid mechanics limits, as compressible-incompressible,
kinetic-macroscopic, viscous-inviscid; adaptive Navier-stokes solver via
wavelets, well-posedness of the evolutionary Navier-Stokes equations in 3D;
existence theory for the incompressible Navier-stokes equations in exterior
and aperture domains. All six articles present significant results and
provide a better understanding of the problems in areas that enjoy a
long-lasting attention of researchers dealing with fluid mechanics PDEs.
Although the papers have the character of detailed summaries, their central
parts contain the newest results achieved by the authors who are experts in
the topics they present.

April 23, 2001
Hyatt Regency Hotel, San Francisco Airport
San Francisco, California

In conjunction with IEEE IPDPS 2001
(The 15th International Parallel and
Distributed Processing Symposium)

Efficient parallel solutions have been found to many problems.
However, there still exists a large class of problems, known as
irregularly structured problems, that lack efficient solutions and
systems support. The workshop on solving irregularly structured
problems in parallel is the eighth in the series, after Geneva,
Lyon, Santa Barbara, Paderborn, Berkeley, San Juan, and Cancun.

Scope: Irregular 2001 aims at fostering the cooperation among
practitioners and theoreticians of the field. Papers for oral
presentation are solicited in all research areas related to
parallelism of irregular problems, including but not limited to:
data structures and graph algorithms, numerical algorithms, mesh
and sparse matrix computations, approximation and combinatorial
optimization, parallel languages and models, compiler optimization
and runtime systems, caching, load balancing and scheduling, resource
management (I/O, memory, and CPU), performance prediction and
simulation, Internet computing and data-intensive applications.

Publication: Workshop papers will be included in the IPDPS Workshop
Proceedings published by IEEE Computer Society. For more information
on IPDPS 2001, Check Some of the previous
proceedings of the Irregular Workshops appeared as LNCS 980, 1117,

Development of a higher order finite difference code for direct and
large eddy simulations of complex flows


We are looking for a post-doc for a two year position at the
Department of Mechanics, KTH and the
Department of Computational Aerodynamics, FFA
to work with the development of a higher order
finite difference code for direct and large eddy simulations of
complex flows. We are looking for someone with a PhD in a numerical
analysis or fluid mechanics related area with substantial programming
experience. You will work in an integrated project team consisting of
researchers from the Department of Mechanics, KTH, the Aeronautical
Research Institute of Sweden and the Department of Scientific
Computing, Uppsala University.


The high-order discretizations of the incompressible Navier-Stokes
equations will be used in simulations of complex flow problems where
the computational meshes are of curvilinear structured type. High
order methods are more efficient and less memory demanding than first
and second order methods used routinely today.

The development of a solver for direct numerical simulation of
turbulent flow has started. This code will form a basis for inclusion
of large eddy simulation (LES) models. The code development builds on
higher order compact finite difference methods.

The code will be used to simulate turbulence phenomena in
complex geometries. In particular the first aim is to simulate turbulent
flow separation in an asymmetric diffuser, a case where ongoing
experiments are performed at the Department of Mechanics. We envision
that the post-doc taking this position will be the first to actually
use the code in a real application.

See for more information about the
project or for more information
about the research group.

As an extension to the original proposal, the subject of research can be
'Traffic modelling'. SISTA/COSIC is also involved in another project on
traffic research: 'Traffic Congestion Problems in Belgium: Mathematical
Models, Analysis, Simulation and Control' (SSTC MD01/24).

SISTA/COSIC is currently doing research on identification of traffic
flow patterns and on control of traffic flows on highways. A fundamental
requirement for traffic research is knowledge of the information on
turning movements and total number of vehicles through an intersection.
The problem is then, based upon traffic flow measurements, to identify
the entries of the origin- destination (O-D) matrix, i.e., the
probabilities of vehicles entering one leg of an intersection and
exiting another in an intersection. This O-D matrix is time dependent
and so we are working on fast estimation algorithms to make on line
estimation feasible. A second important research topic in the traffic
field is the model based development of control schemes for Advanced
Traffic Management Systems on highways, such as: ramp metering, variable
message signs, dynamic route information panels...

Subject: Research Position at ZIB-Berlin


Starting with October 1, 2000 we expect to have an opening
at the German BAT IIa/Ib level (gross salary approximately
8,800 DM per month) with a duration of three years in the
following project.

Our industrial partner operates several warehouses within
the same city. Some of these warehouses are too small to
hold sufficient stock of each product for the day; therefore,
goods are constantly transferred between warehouses by
a shuttle service consisting of several trucks. Part of
the demand is known in advance, part is stochastic and has
to be estimated from available statistical data.
The task is to find a schedule that distributes the goods
between the warehouses by means of the trucks so that demand
can be satisfied on time with high probability. This requires
the development of a stochastic model of the demand, a basic
understanding of the logistics involved, the development and
implementation of optimization methods, and the evaluation of
these approaches in simulations. In this you will be part of
a young team of open-minded researches that will help you to
get into the subject but also expects that you are prepared
and willing to share responsibilities.

- advanced degree in mathematics or computer science
- profound knowledge in at least one of the following fields:
+ convex optimization
+ stochastic programming
+ stochastic processes
+ combinatorial optimization
- advanced programming skills in C/C++
- knowledge of German is an advantage; otherwise, English is
necessary and you should be willing to learn German in order
to communicate with our industrial partners.

We expect that you have a strong commitment to the project and
to research in this field, that you are capable of working in a
team and acquaint yourself with new fields and skills when needed.

ZIB is a research laboratory of the state of Berlin, Germany.
You will be part of the optimization group within the Scientific
Computing department. The optimization group consists of roughly
twenty young scientists from various countries and has a very
strong record of successful industrial projects.
ZIB maintains a well equipped library and is in close contact
to the three universities in Berlin. It offers excellent
