**Subject: Quadrature over Tetrahedra**

Two weeks ago I posted a message to NA Digest asking about quadrature

over tetrahedra. I received many helpful responses. I also received a

number of messages asking me to post a summary. I have written a

summary, but since email is still arriving, I will probably want to

update my summary a few more times. Therefore, rather than including it

here, I have put the summary in my website at:

http://www.cs.cornell.edu/home/vavasis/quad.html

Thanks to the many people who responded.

**Subject: Question on Hybrid Methods in Elastodynamics**

Question on mixed/hybrid methods in elastodynamics

I am looking for extensions of mixed or hybrid finite

element methods to the dynamic case, in particular in

dynamic elasticity. Does anybody know of papers or

work done in this direction?

I am working in the field of mechanical multibody systems

(also known as constrained mechanical systems).

There, a hybrid formulation seems very natural for

the equations of motion if both rigid and elastic bodies

are part of the technical system.

Thanks a lot,

Bernd Simeon

**Subject: Cray T3E User's Guide available in Web**

Center for Scientific Computing (CSC), the Finnish center for scientific

computing and data communications, has published the second

edition of a user's guide to the Cray T3E.

The guide is intended primarily to the users of the T3E at CSC, but most

of the material is useful for any Cray T3E user.

The user's guide (124 pages) is available in English in Adobe Acrobat PDF

format at the WWW address

http://www.csc.fi/oppaat/t3e/

The emphasis of the guide is on scientific software development in the T3E

environment, covering subroutine libraries, code optimization,

interprocess communication and programming tools. The guide contains also

an overview of the T3E hardware.

**Subject: Comment on Sir James Lighthill**

COMMENT ON SIR JAMES LIGHTHILL

Sir James Lighthill F.R.S., founder President of the Institute for

Mathematics and its Applications, was one of the scientists who were

interviewed by Louis Wolpert, for his BBC Radio series "Passionate Minds",

published by OUP in 1997. Here is a passage from that interview, on pages

62-63:

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

Wolpert: `Now most of your work has been in fluids. Is there

something about fluids that appeals to you?'

Aha, yes, I think so! I have a sort of general pleasurable feel

about fluids and, of course, I'm very interested in flight, and although I

worked entirely on aeronautical flight in those days, I subsequently did

very comprehensive studies of animal flight - birds, bats and insects -

during my later period in Cambridge, working with the zoology department

there. And my hobby is swimming; I have a great deal of interest in the

ocean - ocean waves, ocean currents, ocean tides - and so I enjoy observing

all that when I swim. And then I have a fellow feeling for the swimming

animals, and I've written papers about almost all varieties of swimming

fishes and invertebrates, and quite a lot of work on micro-organism

locomotion.

Wolpert: `Part of your passion for fluids is swimming?'

Yes, indeed.

Wolpert: `Do you swim a lot?'

Yes, I do a three-mile swim every weekend just to keep fit.

Wolpert: `And in the holidays?'

In the holidays I always do each year an adventure swim, which I

do, partly because it's good for all of us to have an adventure every so

often, but partly because when I was at Farnborough I was working with test

pilots, and I was conscious that they were actually depending on the

scientific work that was done; they staked their lives on the correctness

of the science. I've done a lot of work on ocean waves and tides and

currents, and I feel I understand them well enough to be quite prepared to

swim in them, because with my theoretical knowledge, supplemented by an

immense amount of experience in swimming in these conditions, I can swim

safely; and have an exciting adventure in the process. So I do this,

usually choosing swims where there are quite difficult currents to deal

with. Sometimes one swims around islands, sometimes one swims between one

island and another.

Wolpert: `Like what?'

Well one of my famous swims is the one around Sark which I've done

five times, and one of them was during a south-westerly gale which was the

one that actually caused the Fastnet disaster. So one needed quite a lot of

nerve and stamina to complete the swim on that day, but it really was

rather an exciting experience. But I've swum between two of the Azores

which have quite a strong current between them. I've swum around an

actively erupting volcano, namely Stromboli, and watched eleven separate

eruptions from the side where you can see the volcano, where incidentally,

the water is the temperature of a hot bath because that's the side the lava

comes into the sea. And I've swum around Lundy, and my most recent swim was

round Ramsay island where there are exceptionally strong currents off the

southwest coast of Pembrokeshire.

Wolpert: `Do you actually use your knowledge of waves and tides in

order to do it?'

Oh, enormously, yes. I mean during this Fastnet swim I was

constantly having to add up vectorially my swimming velocity and the

current velocity, and the wave drift due to these very powerful waves. It

was rather interesting. I was really having to swim at right angles to the

direction I wanted to go in, which you often have to do, of course.

Wolpert: `I don't think many of us [laughter] would recognize that.'

And, of course, you meet seals and all sorts of interesting animals

who have a fellow feeling with swimmers when you do these swims.

Wolpert: `It's very nice applied mathematics I must say. [l\Laughter].'

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

Sark is the smallest of the Channel Islands. From my own experience of

swimming off Sark (I never attempted to swim around that island), I was

aware that the currents and rocks make quite challenging conditions for

swimmers.

And on July 28 I was shocked to learn from Gene Golub that Sir

James Lighthill died on July 17 in a swimming accident near the Isle of

Sark.

Position at CERFACS

Space missions using altimetry are a major component for the global

monitoring of the oceans. The French-American TOPEX/POSEIDON mission is

the current best example of such an approach. The NASA-CNES JASON

project will follow TOPEX after year 2000 and will have improved performance.

The objective is to know JASON's altitude with a precision of 1 cm rms

(the error level for TOPEX is currently around 3 cm using the DORIS and

Laser tracking systems). JASON will also use DORIS and Laser, as well as

a GPS receiver.

CNES is in charge of the precise orbit determination of JASON. It is thus

necessary to improve the processing of GPS measurements at CNES in order

to reach the required accuracy through a combination of GPS with the other

two systems. Correct use of GPS phase measurements is a keypoint for this

objective.

CERFACS has been charged by CNES to develop accurate algorithms to compute

the phase ambiguities associated with the GPS measurements. In this context

we are looking for a researcher at post-doc level with experience, interest,

and background (with publications) in scientific computing to participate

in the development of these algorithms. The position is already open and

should be filled as soon as possible.

The position is in the Qualitative Computing Group at CERFACS, whose main

research activities are

- study of the stability and the reliability of numerical methods,

specifically in the neighbourhood of singularities,

- design of robust codes for computing some eigenelements of very large

and nonnormal matrices (Arnoldi Tchebycheff method),

- influence of high nonnormality on reliability of numerical methods,

- software tools for assessing the quality (reliability, robustness) of

numerical methods.

This group is part of the Parallel Algorithms Project lead by Iain Duff.
