Subject: Calendar

[The Wavelets Digest, edited by Wim Sweldens (sweldens@math.scarolina.edu),
includes a "Calendar of Events". This seems like a good idea and so here
is the first NA Digest Calendar. We'll include the Calendar in the NA Digest
about once a month, and we'll list all the meetings, conferences and workshops
that have been announced in recent issues. I've compiled this from issues
1-14 of the 1994 Digest, but I may have missed some announcements, and there
are probably other relvant meetings. So, if I missed one, or you have one
that should be included, please drop me a note. -- Cleve]

Subject: Query on Programs in Scientific Computing

Query on Programs in Scientific Computing

I would like to obtain information on how the general area of Scientific
Computing is fitting into educational institutions. Is it a department,
a special program within a department, an interdisciplinary program?
Is it located in the College of Engineering, a College of Liberal Arts,
or where? Is it just a graduate program, or are undergraduate programs
being developed? What kind of faculty are associated with formal
institutional programs in Scientific Computing? What kinds of curriculum
are being developed? Is Scientific Computing being combined with other
areas, e.g. general applied mathematics, CFD, etc?

I would welcome any information you have. Because of local interests, I
will try to develop a summary of what I receive, to give some kind of
overview.

Thanks,

Subject: Conjugate Gradients Made (Almost) Easy

Now available by FTP:

An Introduction to the Conjugate Gradient Method
Without the Agonizing Pain

Jonathan Richard Shewchuk
jrs@cs.cmu.edu

55 pages, >> 62 illustrations <<

This technical report is the most intuitive, figure-filled introduction to the
Conjugate Gradient Method I am capable of writing. I've designed it both for
interested people who want a good basis for understanding iterative methods and
their convergence analysis, and for teachers who want to include CG in their
courses. This report is being used in graduate courses in the Computer Science
and Civil Engineering departments here at Carnegie Mellon. A separate file
is available that contains full-page copies of the figures, suitable for
transparencies.

The idea of quadratic forms is introduced and used to derive the methods of
Steepest Descent, Conjugate Directions, and Conjugate Gradients. Eigenvectors
are explained and used to examine the convergence of the Jacobi Method,
Steepest Descent, and Conjugate Gradients. Other topics include
preconditioning and the nonlinear Conjugate Gradient Method. I have taken
pains to make this article easy to read. Sixty-two illustrations are provided.
Dense prose is avoided. Concepts are explained in several different ways.
Most equations are coupled with an intuitive interpretation.

The report is available by anonymous FTP to REPORTS.ADM.CS.CMU.EDU (IP address
128.2.222.79) under the filename 1994/CMU-CS-94-125.ps .

Comments and corrections are welcome.

Subject: Bessel Function Suite for MATLAB

A new suite of routines for computing Bessel functions is now available
for MATLAB. The core of the suite is a Fortran MEX file based on a
Bessel function library written by D. E. Amos at Sandia National
Laboratory several years ago. Several M-file functions provide access
to the Fortran core.

Bessel functions of complex argument are fully supported. Both the
index and the argument can be arrays, so entire tables or basis sets
can be generated with one statement.

The primary functions in the suite are:

BESSELJ(NU,Z) Bessel functions of the first kind,
BESSELY(NU,Z) Bessel functions of the second kind,
BESSELI(NU,Z) Modified Bessel functions of the first kind,
BESSELK(NU,Z) Modified Bessel functions of the second kind,
BESSELH(NU,K,Z) Hankel functions,
AIRY(K,Z) Airy functions.
BESSELMX(...) The Fortran MEX file core library.

The Bessel suite is distributed via anonymous FTP from
ftp.mathworks.com (144.212.100.10)
in directory
pub/mathworks/toolbox/matlab/specfun

Subject: Harwell-Boeing Connection to MATLAB

New software is available which facilitates MATLAB access to sparse
matrices in the Harwell-Boeing Sparse Matrix collection.

The Harwell Boeing collection is available via anonymous FTP from
the CERFACS research laboratory in France:
orion.cerfacs.fr (130.63.200.33)
The collection is in directory
pub/harwell_boeing
A compressed, postscript file contained a detailed user's guide is
pub/harwell_boeing/userguide.ps.Z

The new conversion software is available via anonymous FTP from
the MathWorks:
ftp.mathworks.com (144.212.100.10)
There are two files in directory
pub/mathworks/toolbox/matlab/sparse
The first file is hbo2mat.f, Fortran source code for a stand alone
program which reads Harwell-Boeing data files and uses the MATLAB
External Interface Library to convert them to .mat files. The second
file is hbo.m, a MATLAB function which loads one of the .mat
files and completes the conversion.

Subject: Adaptive Grid Solvers Available

ADAPTIVE GRID SOLVERS FOR PDES IN 2D AND 3D

To solve time-dependent partial differential equations often a
straightforward Method of Lines approach is used. The PDE is discretized
in space and the resulting system of ODEs is solved in time with a robust
`off-the-shelf' solver. The spatial grid used can be either uniform or
nonuniform but is invariable for the time interval.
For problems with steep and moving fronts this can be an inefficient
approach since too much grid points are needed at areas where the solution
(no longer) has large spatial gradients.

For this class of problems we have developed at CWI the software package
VLUGR, a (vectorizable) adaptive-grid finite-difference solver for
time-dependent PDEs in 2 or 3 space dimensions. The PDEs should be defined
on an arbitrary domain bounded by right-angled polygons (2D) or
polyhedrons (3D). The spatial operator may contain at most second-order
derivatives (including mixed derivatives).
To resolve the steep gradients in the solution Local Uniform Grid Refinement
has been employed. At each time level the domain is covered by a, uniform,
coarse base grid and nested finer uniform subgrids are recursively created in
regions with high spatial activity. The corresponding initial boundary value
problem for each grid level is solved with an implicit time integrator (BDF2).

The packages VLUGR2 (for PDEs in 2D) and VLUGR3 (3D) are written in
ANSI Fortran 77.

HOW TO GET IT

1) Via World-Wide Web. Open the URL
http://www.cwi.nl/ftp/gollum
and then select the package you desire.

2) Via anonymous ftp at
ftp.cwi.nl (192.16.184.180)
Change directory to pub/gollum/VLUGR2 or pub/gollum/VLUGR3

The directories contain a README file, the compressed shar file of the
source, and the compressed postscript files with the papers describing
the algorithms, the code, and how to use it.
