BACKGROUND
A very wide variety of processes involve wave propagation and transport
phenomena. Numerical simulation and prediction, particularly for scientific
purposes, demand the use of accurate numerical methods for solving the associated
systems of partial differential equations.
This is most evident in acoustics, when attempting to evolve weak signals
for long distances and for long times or in the simulation of turbulent flow
when attempting to capture small structures on relatively coarse grids.
In addition to the classical requirement of conservation, of fundamental
importance is high accuracy in both space and time for all processes involved
(e.g. advection, reaction, diffusion, dispersion). However, as is well-known
from Godunov’s theorem, accuracy of linear
schemes greater than one brings in the Gibbs phenomenon, producing solutions
with spurious oscillations. The real challenge is then to construct non-linear
(non-oscillatory) schemes of high accuracy, even for solving linear problems.
Significant advances have been made in the last two decades on the
construction of conservative, non-linear schemes of high order of accuracy in
both space and time. These advances were pioneered by the family of TVD (Total
Variation Diminishing) methods, by now a well-established approach that
produces relatively simple and practical second-order schemes. To go beyond
second-order, a high degree of sophistication is required.
There are at present several approaches that, at least partially, fulfil
some of the basic requirements. Examples include the ENO method and its variant
the WENO method, the discontinuous Galerkin Finite
Element methods and the ADER approach.
THEMES
OF THE CONFERENCE AND CONTRIBUTED PAPERS
Algorithm design, analysis and applications of non-linear schemes of
accuracy greater than two, following the finite difference, finite volume and
finite element approaches for wave propagation, flow and transport phenomena.
Potential contributors are invited to submit an abstract of no more than two
pages in ps or pdf format
via email to the organizers.
NO
CONFERENCE FEE
NO conference fees will be charged. Expenses for travel and subsistence
are the responsibility of each participant.
20
GRANTS FOR YOUNG SCIENTISTS
There will be 20 grants for young scientists (PhD students or
post-doctoral fellows) that will cover in full all local subsistence expenses
(hotel and meals for the duration of the conference). Potential beneficiaries
are invited to submit a CV and a letter of recommendation from the academic
supervisor to the conference organizers.
REGISTRATION,
ACCOMMODATION AND OTHER INQUIRIES
Early registration is advised, as our objective is to limit the number of
participants to allow for greater interaction and to avoid parallel sessions.
The conference secretary, Mr Micheletti, will help you with hotel
information and bookings and other administrative aspects of the conference.
