Research Projects
Over the past years, the Institute for Scientific Computing has been fortunate to receive
support from the Deutsche Forschungsgemeinschaft (DFG) within the Excellence Initiative,
two Collaborative Research Centres (SFB), a Research Training Group (GRK), and a Priority
Programme (SPP).
The Excellence Initiative aims to both promote top-level research and improve the quality of
German universities and research institutions, thereby making a significant contribution to
strengthening science and research in Germany in the long term, improving its international
competitiveness and raising the profile of the top performers in academia and research. This
national initiative involves three lines of funding: (a) graduate schools to promote young
researchers, (b) clusters of excellence to promote world-class research, and (c) institutional
strategies to promote top-level university research. The Institute for Scientific Computing is
involved in the graduate school "Aachen Institute for Advanced Study in Computational
Engineering Science" (AICES) and the cluster of excellence "Integrative Production
Technology for High-Wage Countries".
FLOWRUN―Numerical simulation and optimization of flood-induced flow phenomena
using a parallelized SPH-code
J. Willkomm, C. Bischof, M. Bücker
The objective of this JARA research project is to carry out a novel, coupled, numerical
investigation of hydromechanical flow phenomena via an interdisciplinary approach of the
disciplines hydraulic engineering, informatics, and mathematics. In this feasibility study the
flow over a stepped, pooled spillway is computed on a parallel computer and combined with a
sensitivity analysis based on automatic differentiation. For this application an implementation
of the SPH-method (Smoothed Particle Hydrodynamics) is intended, which will enable the
efficient numerical computation of relevant flows in the long term. In particular in fluid
mechanics, high-performance computing has gained in importance due to the long-term and
large-scale applications in hydraulic engineering. The participating scientists from Hydraulic
Engineering and Water Resources Management (IWW), Scientific Computing (SC) and
Continuous Optimization (OPT) aim at establishing an innovative and sustainable cooperation
in the field of hydro-informatics.
Computational Differentiation in Numerical Flow Analysis
A. Rasch, A. Vehreschild, C. Bischof, M. Bücker
This project of the Collaborative Research Centre (SFB) 401, "Modulation of flow and fluid--
structure interaction at airplane wings", is aimed at developing efficient techniques for
