Subject: NA Digest too dull?

NA Digesters:

How's this to generate some controversy? About 6,7 years ago in a
conversation with one of LANL's foremost applied mathematicians, I declared
that CFD is dead. This person, whose maturity and integrity match his
life-long technical achievement, corrected me and said that CFD is a
"mature" field.

CFD is a "mature" field in the sense that there has been no great
innovation. No "must read" paper in the field has been written in the last
10 years. While I applaud the effort by many applied mathematicians to use
their tools to solve important problems in industry and biological
sciences, I believe there is still way too much emphasis (at least in the
literature) on devising specialized, high-order schemes for the
one-dimensional gas dynamics equations, methods so fragile that couldn't
possibly have any applicability in real-life problems.

Some questions I would like to pose:

1. Is CFD a means to itself, or its purpose is to help gain insight in
complex systems?

2. If CFD is a "pure science" for its own sake, what may be considered a
major breakthrough? I would like to exclude any major breakthrough (such as
an O(n) scheme for anything) in numerical linear algebra. For example, I
would consider being able to estimate (sharply) computational errors for a
real scheme (so I'm not talking about an "a posteriori error estimate" or
the "rate of convergence") would be a real big deal.

3. If the purpose of CFD is to help us gain insight into complex systems,
what are some major challenges? One example I have in mind is in the
application to multiphysics: not just physics of fluids, but incorporation
of physics of multiple time/spatial scales, physics at different
temperature regimes, physics of multiple material phases, etc.

Today I am not actively working in CFD; among other things, the
disenchantment I have with the direction CFD was headed has led me to a
different scientific career. I doubt I'm the only one. Perhaps some of you
also care to comment on your opinion of the state of CFD today.

Yours Truly,
Karen Pao

Subject: Small tutorial on parametric model reduction


I have made available a small tutorial on parametric model reduction at

It shows that parametric model reduction is possible, well, at least
for the problem in question. One can approximate an original dynamic
system of dimension 4257 by a reduced system of dimension 41 while
preserving three parameters in the system matrix in the symbolic form.
It also shows that the the approach employed is quite empirical and
there is great need for mathematical research.

The tutorial is made in Mathematica. If you do not have it, you can
browse the pdf of the notebook with the results

I should say that the implementation is pretty straightforward: a
computation of a few Krylov subspaces.

Best wishes,

Evgenii Rudnyi

publication of the manuscripts for this special issue will conform to the
rules for regular papers in the Mathematics and Computers in Simulation. To
be included in the special issue, manuscripts must be emailed to Guest Editor
Professor Yiming Li prior to the beginning of the workshop (authors should
identify this as a WSCEE submission), and the papers will be reviewed
according to the usual IMACS journal standards. Only .pdf is accepted for
submission! Please send your correctly formatted (see below) papers to the

Applications are invited for a 2-year postdoctoral Research Position/PhD
Position funded by the FWF Austrian Science Fund at the Institute for
Mathematics and Scientific Computing of the University of Graz, Austria.
The project will last three years.

The goal of this project is to theoretically investigate quantum control
applications in semiconductor nanostructures. The expected impact of the
project is in the field of simulation and optimization of quantum control in
quantum systems.

The work will involve (a) development of fast and efficient computer
algorithms suited for quantum optimal control applications of open quantum
systems, and (b) simulation of quantum optimal control problems in
nanostructures. The work will cover both aspects of numerical mathematics and
of theoretical physics, and will be carried out in a joint interdisciplinary
collaboration between mathematics and physics.

Applicants must hold a PhD (for PostDoc position), and should be experienced
in numerical analysis, ideally optimal control theory and/or inverse problems,
and possess some background in physics. They should be competent programmers,
and willing to collaborate in this interdisciplinary project.

Applicants should send (to the addresses given below) a curriculum vitae,
bibliography of published work, a one or two-page statement of research
interests, and a letter of recommendation.
