zum Forschungsseminar 'Computergrafik, Bildverarbeitung und Visualisierung'
am Mittwoch, den 17. April 2019, 13:00 Uhr,
Raum P-701 im Paulinum am Augustusplatz.
===============================================
Wir hören einen Vortrag von
Christian Blecha
mit dem Titel:
"Analysis of coupled thermo-hydro-mechanical simulations of
a generic nuclear waste repository in clay rock using fiber surfaces".
zum Inhalt:
The use of clean and renewable energy and the
abandoning of fossil energy have become goals of many national
and international energy policies. But even when once accom-
plished, mankind has to take charge of the relics of the current
energy supply system. For example, due to its harmful effects,
nuclear waste has to be isolated from the biosphere safely and
for sufficiently long times. The geological subsurface is consid-
ered as a promising option for the deposition of such by- or
end products. In order to investigate the long-term evolution of
a repository system, a multiphysics simulation was performed.
It combines the structural mechanics of the host rock, the
fluid dynamics of formation fluids, and the thermodynamics
of all materials resulting in a highly multivariate data set. A
visualization of such multiphysics data challenges the current
methodology. In this article, we demonstrate how an analysis
of a carefully selected subset of the variables in attribute space
allows to visualize and interpret the simulation data. We apply
a fiber surface extraction algorithm to explore the relationships
between these variables. Studying the temporal evolution in
attribute space, we found a regionally bulge that could be
identified as an effect of the nuclear waste repository because
it can be clearly separated from the natural geophysical state
prior to waste disposal. Furthermore, we used the extracted
fiber surface as a starting point to examine the distribution
of other variables inside this area of the physical domain.
We conclude this case study with lessons learned from the
visualization as well as the geotechnical side.

Alle Interessierten sind im Namen von Professor Dr. Scheuermann herzlich
eingeladen.
Mit freundlichen Grüßen
