**Subject: Mode Matching Code**

I have written a mode matching code that computes the scattering matrices

(S11, S12, S21, S22) of a _rectangular_ _waveguide_ _cross-section_ _jump_.

No assumptions as to symmetry have been made, provided that the cross-section

of the smaller guide lies within the boundaries of the bigger one.

The program is written in f77 and assumes that one has the LAPACK

compiled as library, as well as the BLAS (preferrably machine-BLAS). I have

used the cpp (C preprocessor) to make automatic conversion of declarations,

generic functions and LAPACK/BLAS-names to double precision. e.g. CGETRS ->

ZGETRS. It has been fairly well tested so far; we've calculated filters and

accelerator sections with it.

Anyone interrested send a mail to the address below and I'll be happy to

send the code. BTW, it comes as UNIX shell archive (shar).

Cheers, Bengt (email: littmann@tetibm3.ee.TU-Berlin.DE)

**Subject: Query about Fortran 90 to C Translation**

Dear Members of Na-net,

I would like to know if there is a Fortran -> C Translator, which is suitable

for use with Fortran90. I know that also the F90 compilers can do this.

The reason why I would like to know this is because we are using Linux

for the program development. Up to now netlibs f2c worked very well,

(as a preprocessor for the Gnu C Compiler) but it does not support F90.

Unfortunately we do not have a F90 compiler running under Linux, but we would

like to write programs in F90.

Any hints and suggestions are very welcome.

**Subject: Software for Partitioning Graphs**

NEW SOFTWARE FOR PARTITIONING GRAPHS

Many problems which arise in the course of scientific computing can be

conveniently described in terms of graph partitioning. A prominent

example is the problem of decomposing a large, unstructured grid across

the processors of a parallel computer. Other applications include generating

nested dissection orderings for sparse matrix factorizations and devising

efficient circuit layouts.

We have developed a software package called "Chaco" which implements a

variety of graph partitioning algorithms. These include the spectral

bisection, quadrisection and octasection algorithms, the inertial method,

the Kernighan-Lin method, and a multilevel partitioner. Techniques can

mixed and matched as well, for example Kernighan-Lin can be applied to

refine a spectral partitioning.

A user's guide and papers describing the algorithms are available by

anonymous ftp to cs.sandia.gov in the directory pub/tech_reports/bahendr.

The software can be obtained at no charge under a research license agreement

and may also be licensed for commercial application. Interested parties

should contact one of the authors at the addresses given below.

**Subject: A Matrix Eigenvalue Problem**

The following eigenvalue problem was sent to me by Professor J. Luttinger,

a theoretical physicist at Columbia. Please send your responses to Professor

Luttinger at the e-mail address given at the end of his msg.

The problem is concerned with the representation of the largest

eigenvalue of a class of matrices. They are all symmetric and positive in the

sense of Perron. The largest eigenvalue is represented as an integral (from

zero to $2\pi$) of the log of a trigonometric polynomial. Here are a couple

that are fairly easy to work out:

1) The matrix is 2x2,

$$M_2 = \pmatrix{e^k&e^{-k}\cr e^{-k}&e^k \cr}\ , {\rm k}\ real}$$

The result is $2 log {\lambda_m\over 2} = {1\over 2\pi}

\int_0^{2\pi} d\theta log (cosh 2k + sinh 2k\ cos\ \theta).\ \ \lambda_m$ is

the largest eigenvalue of $M_2.$

2) This matrix is 4x4:

$$M_4 = \pmatrix{e^{2(k_1+k_2)}&e^{-k_1}&e^{-2k_2}&e^{k_1}\cr

e^{-k_1}&e^{2k_2}&e^{k_1}&e^{-2(k_1+k_2)}\cr

e^{-2k_2}&e^{k_1}&e^{2(k_1+k_2)}&e^{-k_1}\cr

e^{k_1}&e^{-2(k_1+k_2)}&e^{-k_1}&e^{2k_2}\cr}, k_i\ real}.$$

The result is

$$log {\lambda_m\over 4} = {1\over 2\pi} \int_0^{2\pi} d\theta log(cosh(2k_1)

cosh(2k_2) + sinh(2k_1) cos\theta + sinh(2k_2) cos2\theta).

(The largest eigenvalue of $m_4$ is again given by $\lambda_m.)$

There are other problems of the same general class, but with matrices

that get larger and larger. If done directly they involve seemingly hopeless

amounts of algebra, and yet I have reason to believe that a fairly simple

closed form exists.

**Subject: Computational Fluid Dynamics Lectures in Belgium**

25th ANNUAL COMPUTATIONAL FLUID DYNAMICS LECTURE SERIES

VON KARMAN INSTITUTE FOR FLUID DYNAMICS (BELGIUM)

21-25 MARCH, 1994

The aim of this annual lecture series is to provide in-depth presentations

on well-established methods and on recent advances in the field of numerical

flow simulation. The program is at a specialist level complementary to the

Introduction to Computational Fluid Dynamics (Lecture Series No. 2).

This year the course will recognize the 25th anniversary of the VKI lecture

series in CFD by focusing on the key algorithmic achievements of the past 25

years which constitute the basis of modern CFD for aerodynamic flows today :

shock capturing TVD high resolution schemes for compressible flows, multigrid

acceleration techniques, advances in linear algebra (Generalized Minimum

Residual and Related Methods), unstructured grid methods and solution

adaptivity. Key scientists at the origin of some of the most successful methods

have been asked to review the lessons learned form the past, in order to

determine the important area's where future developments will take place.

With respect to high resolution shock capturing space discretization, both

finite volume methods, cell vertex residual distribution schemes and SUPG

finite element discretizations will be reviewed, emphasizing the different

nonlinear mechanisms in the schemes which allow for monotonic discontinuity

capturing. For application to systems of hyperbolic equations, both the

classical Riemann solver flux difference splitting approach and the more recent

multidimensional flux balance splitting methods will be discussed.

The second subject will be on fast iterative solvers for efficient steady

state computation. Both Krylov subspace methods and multigrid methods will

receive considerable attention, with application to flow problems on structured

as well as unstructured grids.

In addition to these two major subjects, attention will be given to a new

development of non-dissipative numerical schemes suitable for aeroacoustics.

Lectures will be given in English and printed notes will be distributed

to participants at registration on the first day.

The speakers include:

N. Kroll, DLR, Germany.

T.J. Barth, NASA Ames Research Center, California, USA.

P.L. Roe, U. Michigan, Ann Arbor, USA

R. Radespiel, DLR, Germany.

exists to promote communications between the Numerical Algorithms Group (NAG)

and users of the services and products NAG develops, maintains and markets. It

provides information to NAG on the requirements of users, who are in turn kept

informed of developments in services.

NAGUA Conferences consist of both business and technical sessions providing an

opportunity for users to meet each other and members of NAG, to hear about

others' experiences and to find out about new products and services.

Attendance at the conference is open to any user of NAG's products and

services.

The thirteenth conference of the NAG Users Association will be held in the

historic City of Oxford.

**Subject: NASA Workshop on Parallel Numerical Algorithms**

ICASE/NASA Langley Workshop on Parallel Numerical Algorithms, 23-25 May 94

Purpose:

To acquaint developers of high-performance applications codes based on

partial differential equations or integral equations with the state of

the art in core areas of algorithms and the parallel computational

environment, and to engage representative experts from the algorithms

community in discussions about their applicability.

Rationale:

A principal parallel challenge in large computational fluid dynamics,

computational structural mechanics, and computational electricity and

magnetism problems is the implicit solution process. Hence, these

applications areas meet in a common algorithmic core. However, results

on model problems are often not transferable. The workshop will promote

more useful development and more rapid integration of parallel

algorithms in high-performance NASA-related applications.

Can you recommend a means to solve an unconstrained minimization

For our application, in order to achieve adequate precision in the

final solution we need the calculation to be performed in at least

We have double precision Fortran routines for the objective

function, gradient, and Hessian. We have access to several brands
