Subject: Mimetic Discretizations


I am organizing a web site devoted to
Mimetic Discretization of Continuum Mechanics
The main idea of these methods is to discretize some mathematical theory
such as vector calculus and then use these methods to discretize problems
in continuum mechanics. These techniques use ideas from vector calculus,
differential geometry (differential forms), and algebraic topology (chains
and cochains). We will plan a workshop for interested parties.

Subject: Workshop in Heidelberg on Reactive Flow, Diffusion and Transport

The Sonderforschungsbereich "Reactive Flow, Diffusion and
Transport" (SFB 359) at the University of Heidelberg
in cooperation with AMIF (Applied Mathematics for Industrial
Flow Problems) is organizing the Workshop

"Adaptive Methods for Flow Computation" (AMFLOW 2001)

in October 22-24, 2001. The local organizers are:
Prof. Rolf Rannacher
Dr. Roland Becker
Dr. Malte Braack

The theme of the workshop is the combination of traditional
methods for numerically solving flow problems with new
approaches to adaptive mesh design and error control.
This includes a posteriori error estimation in finite volume
and finite element methods, techniques for local mesh
optimization, post-processing and efficient solution methods
on such locally refined meshes.

The underlying models are the Navier-Stokes equations for
incompressible as well as compressible flows with special
emphasis on viscous and low-Mach number effects. In addition,
multi-component flows, chemically reactive flows and
multi-phase flows are of interest. Applications of interest
are for example, in micro-flows, chemical flow reactors,
fluid-structure interaction, optimal control of flows, etc.

The program of the 3-day workshop will consist of some
invited survey lectures of 60 min. and contributed talks of
30 min including discussion. There will be time for intensive
The following experts have already agreed to deliver
survey lectures:

1. M. Giles (Oxford):
Error control and post-processing without Galerkin orthogonality;
2. M. Feistauer (Prague):
Adaptive techniques in FV methods;
3. M. Peric (Hamburg):
Practical adaptivity in CFD
4. R. Becker (Heidelberg):
Duality techniques for error control an mesh adaptation
in FE methods.

Submission of talks (title and some lines of abstract) should be
sent before September, 30, 2001 via e-mail.

A limited number of travel grants is available for supporting young
scientists (phd students and post-docs) who want to attend.

The University of Texas - Pan American
Edinburg, Texas USA

Professor Joyce McLaughlin, Ford Foundation Professor of Mathematics
at Rensselaer Polytechnic Institute, will provide 10 one-hour lectures
on "Using Spectral Data to Solve Inverse Problems."

These lectures will be a self-contained and comprehensive exposition on
the use of natural frequencies and selected mode shape measurements to
determine material properties of objects. These lectures will not only
present the newest methods for solving these problems, but also give both
mathematical and experimental insight into how the data depends on the
material properties to be recovered. Emphasis will be on two-dimensional
problems, with a brief introduction and insight given for one-dimensional

Five additional invited speakers will provide supplemental lectures
addressing related inverse problems in mathematics, science, and engineering.

Subject: Research Positions at Delft University of Technology

Joint research project of Shell Int. E&P, Philips Electronics and
Delft University of Technology.

In the Department of Applied Physics (Optics Group) and the Department of
Applied Mathematical Analysis (Numerical Analysis Group) two PhD positions are
available for the project:

"Rigorous modelling of 3D wave propagation for geophysics and
optical recording."

The goal of the project is to develop a rigorous, efficient parallel method
to solve the time harmonic 3D Helmholtz equation for seismic problems and
the time harmonic 3D Maxwell equations for the propagation of light
in optical recording.

Although the physical applications are different,
the geophysical and optical problems have mathematically and
numerically much in common. Due to the complexity in 3D, both models
will need an iterative parallel solver.
This motivated Shell and Philips to collaborate with each other and with
Delft University of Technology in this research project.

The project has just started and Delft University of Technology
would now like to hire as soon as possible two PhD students.
One PhD student will work on the common iterative solver, the other
PhD student will work on the modelling of light propagation in optical
recording. The students will work at Delft University, Shell Rijswijk or
Philips Research Eindhoven.

Subproject 1 Iterative solver for 3D wave propagation

Description: The work consists of developing an efficient (parallel) iterative
solver that can be applied to both the 3D Helmholtz equation
and the 3D Maxwell equations.
The first application will be the modelling in the frequency
domain of a seismic survey for subsurface studies.
The second application will be the modelling of the
light propagation based on the work done in subproject 2.
For further details about the position see

Requirements: the student must have either a masters degree in mathematics or
physics, or an engineering degree. A background in applied
mathematics is necessary, especially good skills in linear
algebra and computing science.

Dr. Ir. C. Vuik (tel. +31-15 2785530), or
Ir. A. Segal (tel. +31-15 2785535).

Subproject 2 Modelling of 3D light propagation for optical recording using
the Maxwell equations

Description: In optical recording a focused laser spot
is used to read and/or write bit patterns on an optical disk.
Because of the demand for higher densities, details on the optical
disk have become smaller than the wavelength of the light.
The polarization of the light is then very important.
A rigorous 3D model based on Maxwell's equations is therefore
needed to study the interaction of the light spot with the disk.
The goal of the project is to extend an existing rigorous
model for 2D structures to 3D and to apply the model
to the study of the interaction of light with the optical disk.
In the first part of the project existing (direct or iterative
solvers) will be used, but the aim is to use
the efficient iterative solver solvers developed
in subproject 1 later. For more details see

Requirements: the student must have a masters degree in physics, applied
mathematics or an engineering degree.
Knowledge of electromagnetism and Maxwell's equations
is necessary and interest in computational physics and good
mathematical skills are required.
