**Subject: Philip Rabinowitz**

In addition to "Methods of Numerical Integration" with

Philip Davis, Rabinowitz was the co-author of

"A First Course in Numerical Analysis" with Anthony

Ralston. I think that was one of the finest general

numerical analysis texts of its day. Its some 550 pages

and contains an enormous amount of excellent material.

**Subject: Matrix Problem**

My colleague, Rajendra Bhatia, has the following problem.

Let T(a) be an nxn upper triangular matrix with the diagonal elements =

a, and the off-diagonal elements for j > i all equal to - 1. Can you

determine the exact singular values? (Bhatia knows the solu'n for a few

values of a.) We know the asymptotic values for some values of a. Let

Bhatia (rbh@isid.ac.in) and me know of your solution.

I believe the answer to this question depends on the goal, that is, whom

you are going to teach. However, to get acquainted with modern

commercial software makes sense for everyone who is going to learn

computational fluid dynamics and heat transfer.

Let us start with the biggest audience: people who plan just use CFD in

practice. Here one of commercial packages is the best choice. I am

working for CADFEM and it has great experience of teaching engineers.

See for example ESoCAET - European School of Computer Aided Engineering

Technology, founded by CADFEM

http://www.esocaet.com/

Then we can consider people who plan to contribute to the future

development. Here programming should be already an important part of

education. Yet,

1) It makes sense to learn commercial packages anyway, as they should

learn the state of the art in the field. Otherwise, there is a danger

that they reinvent the wheel in the future.

2) They should learn programming first. In my view, learning programming

with CFD simultaneously would be really a bad choice.

3) Here one should probably choose not between programming languages but

rather between available libraries.

**Subject: Re: Packages vs languages**

Graham de Vahl Davis posted a question about the relative merits of

commercial packages (CFX, FIDAP, etc.) and programming languages (C++,

Fortran, etc.) for teaching computational fluid dynamcis and heat

transfer. It seems to me that the response depends heavily on to whom

the course would be directed. Are you teaching theory, are you teaching

practice, or are you teaching applications?

A theoretician ultimately is going to require a programming language in

order to try out new algorithms.

A person interested in the practice of CFD will be interested in

commercial packages and the most successful practical methods, but will

also be interested in writing code, at least to demonstrate why some

methods are not successful. This person may also be interested in

writing code that interfaces with a commercial package.

A person interested in applications will want a good commercial package

with sophisticated front ends (mesh generation, etc.) and back ends

(motion pictures). It is a waste of this person's time to learn a

general-purpose programming language.

And remember, too, that there is a third option: general-purpose

problem-solving environments such as Free-FEM, Deal.II, and Overture

come to mind. These provide for problem descriptions at a much higher

level than programming languages yet are applicable to a wide range of

problems using a wide range of techniques.

**Subject: Re: Packages vs languages**

Graham de Vahl Davis asked the NA digest community about the

merits of teaching commercial CFD packages vs teaching how to

program the basic algorithms. I think that it is fair to extend

this question to other types of commercial modeling packages

(e.g. finite elements, ray tracing, etc.).

For engineering and science students, it is my opinion that a

solid core in a programming language, numerical methods, and

scientific computing are preferable over learning to use a specific

package. I do not prefer teaching one language over another. My

opinion is that the important aspect of learning any particular

programming language is "learning to learn" a programming language so

that others may be learned and used confidently in the future. Base

numerical methods are required to understand the elementary building

blocks of larger scale codes and algorithms, for example what it

means for a quantity to be large and small numerically, interpolation,

solving linear and nonlinear equations, and computing eigenvalues. By

scientific computing I mean learning how to combine numerical methods

to build larger scale computer codes to solve a particular problem and

developing a basic understanding of how the program runs on different

computers, memory architectures, in/out of cache, etc. The base

scientific computing step connects to the theory and experiments taught

in the rest of the curriculum (fluid mechanics, mechanics,

electromagnetics, optics, networks, etc.).

My expectation that a new engineer or science graduate should have the

ability to write a program to solve a simple problem and/or to process

and analyze data has turned lately into wishful thinking. I see code

runners that are lost without the base code that they learned to use in

college and/or people that are unable and/or afraid and/or unwilling to

spend the hours necessary to write a code/macro/script to accomplish

something slightly different than what is provided in a commercial code

or to streamline their design/development process.

Ability to learn and use a commercial code is important for design and

development. Knowing how to use a specific code is much less important

to me, especially for a new hiree, than having a good understanding the

the core science/engineering, having the ability to learn something new

and being agressive about writing and using software tools as needed.

Finally, I would like to comment that in my experience, even though many

commercial codes are "closed", communicating with the developer's

technical staff is often an email, online forum post, or phone call away.

The best developers I have worked with have people with a wealth of knowledge

that have helped me understand how their code works and how to accomplish

specific tasks, made example scripts, and maybe even created and distributed

an API or plugin scheme that goes with their code. They may also have

documentation with enough background information and literature references

to obviate the need for a textbook. So it is often possible to learn

something new and/or review something old by taking advantage of their

support.

Please note that these opinions are my own opinions and not those of 3M

Company.

Thank you and best wishes,

TRH

**Subject: Comment to packages versus languages**

In NA Digest Vol. 07, Issue 31, Graham De Vahl Davis asked for a

discussion "packages versus languages". Here are my comments:

The situation: For numerical simulations you must bring together TWO

experts: The engineer that has the technical problem, defines the PDEs,

measures the empirical coefficients and then wants to solve the PDEs.

Now a quite different expert is needed, a computer scientist that knows

the numerical methods, is a programming specialist (HE must know the

programming languages) and he is a specialist for parallelization for

supercomputers. This computer science specialist can be replaced to a

certain extent by standard software packages for everyday problems.

We have developed a black-box solver (FDEM) for arbitrary nonlinear

systems of PDEs on unstructured grids that computes with the solution an

error estimate so that we know the quality of the solution. The code is

efficiently parallelized. We offer a service where in a close

cooperation the engineer gives us his PDEs, we solve them and return the

result in the requested form. I am presently addressing university

institutes and research divisions of high-tech manufacturers for

cooperations in the above mentioned sense. The manufacturers enforce the

use of standard software and university institutes that want to

cooperate with them MUST use the same software. So their research can

never go beyond the possibilities of that software. University

institutes usually cannot afford a computer scientist, so they use also

as far as possible standard software. In most cases these people do no

longer know the PDEs they are solving. They enter some coefficients in

some input tables of the software, that's all. I have now addressed 800

institutions and we are now creating cooperations.

My conclusion: If you teach thermodynamics or fluid dynamics the

students should be able to define the PDEs and boundary conditions for

their phenomena. Then they must look for software that gives wit the

result an error estimate, i.e. a measure for the quality of the

numerical result. As up to now standard software does not deliver an

error estimate, they must do mesh refinement tests until the numerical

error is small. Then they compare the numerical result with the

measurements. If the two results do not coincide the error must be in

their model because the numerical error is small. So you must teach how

to use standard software CRITICALLY. As an example: a cooperating

institute calculated the chemically reacting flow in a micro-reactor

with FLUENT on a very coarse grid. Our error estimator gave 200% error

for the reaction product. We needed with FDEM one hour computation time

on 250 processors of a parallel supercomputer to compute the reaction

product with an error estimate in the 1% range!!!

Report on

II INTERNATIONAL CONFERENCE ON MATRIX METHODS AND OPERATOR EQUATIONS

http://bach.inm.ras.ru

Moscow July 23-27, 2007

Walter Gander and Gene Golub

Following the ICIAM07 meeting in Zurich, a satellite conference was organized

in Moscow; many participants took the opportunity to visit both places. Thus

there was a good mix of speakers from 16 countries and delegates from

Russian-, Ukrainian-, European- and US; this also included the distinguished

Indian scientist Rajendra Bhatia. It was great that many young researchers

from East and West participated. Remarkably, most young Eastern Europeans

could communicate in excellent English, the official conference language.

Eugene Tyrtyshnikov did an excellent job as local organizer. Most foreign

visitors were located in Hotel Soyuz, a former military institution. The

conference site was in the new building of the famous Steklov Institute of

Mathematics of the Russian Academy of Science. Guri Marchuk, the grand old

man and former director of the academy opened the conference with some warm

welcome words. The social program included a visit to the Kremlin and a

banquet in a magnificent hall of the impressive main building of the Russian

Academy of Science.

The Scientific Program was organized in 21 plenary talks and 81 talks parallel

in three sessions divided by the topics: "Matrices and Algorithms", "Algebra

and Matrices" and "Matrices and Applications". The spectrum of the talks was

broad it reached from classical topics from orthogonal polynomials and best

approximation to modern development such as quasi-separable matrices, tensor

factorization and approximation by matrices of low tensor rank. Almost all

talks were in English. A presentation was made by Vladimir Khazanov of joint

work with Vera Kublanovskaya, the great Russian numerical analyst and

co-inventor of the QR method for computing eigenvalues.

Although no best paper award was given, the company Neurok Techsoft sponsored

for the first time "Matrix Prizes" for best young researchers. The first prize

went to Ivan Oseledets from the Institute of Numerical Mathematics, RAS,

Moscow for his excellent contribution: "A new class of low-tensor rank matrices

closed under inversion". Three second prizes went to Olga Markova (Lomonosov

Moscow State University) for the paper "Matrix algebras and their length" ,

Federico Poloni (Scuola Normale Superiore, Pisa, Italy) for the paper

"Exploiting rank structure in the solution of a class of nonsymmetric

algebraic Riccati equations", and Dmitry Savostyanov (Institute of Numerical

Mathematics, RAS, Moscow) for the paper "Matrix tricks in tensor

approximation: 3D-cross method and maximum-volume principle".

Hans Schneider closed the conference with a gracious comment thanking Eugene

Tyrtyshnikov with the words that he was very pleased to see how the field of

Linear Algebra continues to flourish and noting that many new applications and

developments arise from Numerical Linear Algebra.

This is the second meeting of this nature. Another meeting is planned two

years hence. We hope we will see many of our colleagues from abroad at this

exciting event.

**Subject: Glass Corrosion: Industrial Case Studentship, Imperial College & Pilkington**

Glass Corrosion: Parameter estimation in reaction diffusion problems

involving ionic species with limited data

An EPSRC Industrial CASE studentship is available in collaboration with

Pilkington Group Limited and the Mathematics Knowledge Transfer Network in

the UK. The studentship will be based at Imperial College, London in the

Department of Materials and will be supervised by the Head of Department,

Professor Bill Lee and Dr Paul Tangney, who has recently transferred from

Lawrence Berkeley Laboratory. In addition, mathematical support will be

provided by Dr Daniel Lesnic from the Department of Applied Mathematics at

the University of Leeds, who is an acknowledged expert in mathematical

inverse problems.

Many problems in the manufacture and use of glass are associated with the

thermally activated diffusion of ionic species and resultant redox reactions

at the diffusion interface between species with different oxidation states.

This applies to all types of glass, including ancient museum glass of

historical significance, modern float glass and novel glasses used for the

encapsulation and long term storage of nuclear waste. Recent work at

Imperial College has shown that dynamic SIMS (Secondary Ion Mass

Spectrometry) can produce accurate and well defined depth profiles of the

relevant ionic species in glass. These profiles are rich in information and

represent a classic example of a mathematical inverse problem. The aim of

the project is to work back from the depth profiles to elucidate the detail

of the ionic diffusion processes and redox reactions that produced them.

The primary focus of the experimental work will be on the SIMS technique

using state-of-the-art instruments at Imperial College and other

Institutions within Europe, including the University of Warwick and

instrument manufacturers in Germany and France. However, other surface

analysis techniques, such as XPS, SEM, etc. will be used to cross-check and

calibrate the SIMS data. As part of the research the student will have the

opportunity to spend a minimum of 3 months with the industrial sponsor

during the course of their studies, and, as a Mathematics KTN student, there

will be opportunities to attend courses, events and workshops at the

University of Leeds and the Smith Institute.

An individual with a first degree in any of the scientific disciplines with

significant mathematical content and strong interest in mathematical

modelling of physical process will be considered for this opportunity but an

interest in instrumental surface analysis methods is also desirable.

EPSRC CASE studentships are restricted to UK citizens or individuals

normally resident in the UK for the past 3 years. This studentship will be

provided at the standard EPSRC rate of a bursary of £14,600 and home level

fees.

Although the studentship will be available to students who wish to start

later, we are particularly interested in anyone who wishes to commence in or

before October 2007.

Applications will be processed when received, with the expectation that the

post will be filled by 17th August 2007. To apply, please email a copy of

your CV, including the names of 3 referees, to Professor Bill Lee, email

w.e.lee@imperial.ac.uk. Applicants should also complete an on-line

application for a PhD which is available under how to apply at:

www.imperial.ac.uk/pgprospectus. For assistance with the on-line application

please contact Norma Hikel (n.hikel@ic.ac.uk).
