Brief description
Im Projekt P6 der DFG-Forschergruppe 493 soll ein streng partitionierter Ansatz zur numerischen Simulation von Fluid-Struktur-Wechselwirkungen weiterentwickelt und an prototypischen und zugleich technisch relevanten Modellkonfigurationen erprobt werden. Für die Strömungsberechnungen wird der auf kartesischen Gittern arbeitende MAC-Code Nast++, entwickelt für die Behandlung zeitabhängiger laminarer Strömungen viskoser inkompressibler Fluide in veränderlichen dreidimensionalen Geometrien, weiterentwickelt und eingesetzt. Zur Berechnung der Antwort der flexiblen Strukturen bringt das Projekt P10 (Prof. Rank, Dr.-Ing. Düster) einen Löser zur strukturdynamischen Simulation in den partitionierten Ansatz ein. Nach zunächst vorzunehmenden Verbesserungen bzw. Erweiterungen am Ströungscode soll die voll transiente (implizite) Kopplung im Sinne der partitionierten Lösung realisiert und im Hinblick auf Robustheit und Stabilität untersucht und optimiert werden. Zur Validierung soll vor allem das Prinzipexperiment FLUSTRUC-A aus Projekt P4 (Prof. Durst, Dr.-Ing. Breuer, Dipl.-Ing. Lienhart) dienen. Ein weiterer Schwerpunkt der Arbeiten liegt auf der Bereitstellung einer modularen Software-Infrastruktur, die über einheitlich definierte Schnittstellen den einfachen Austausch von Komponenten gestattet und somit in der Forschergruppe beispielsweise zum Vergleich verschiedener Strukturlöser bzw. verschiedener Fluidlöser in unterschiedlichen Szenarien genutzt werden kann. Hierbei findet eine intensive Kooperation der Teilprojekte P6, P8 und P10 statt.

Brief description
Incomplete markets require new statistical, analytical, and numerical methods, to cope with stochastic volatilities or jumps in the stochastic processes, e.g. These are investigated in a joint project of Universität Heidelberg (with focus on modelling, analysis and statistics), Universität Bonn (with focus on numerics) and SCCS (with focus on software development). The goal of our work in the project is to integrate newly developed methods - especially sparse grid techniques - into the framework of ThetaML, a system of
Thetaris GmbH that allows rapid formulation and analysis of complex financial derivatives.

Development of New Methods for the Production of Highly Reactive Polyisobutenes

Brief description
Polyisobutene are used in industry in large amounts. Depending on their molecular weight, they are required for rubber production or applied as adhesives, e.g.. More than 100,000 t of highly reactive polyisobutene are produced per year. Thus, efficiency and environmental compatibility are very important tasks. However, to achieve a high qulity and good productivity, all known production methods require reaction temperatures far below 0 degree celsius and solvents such as methylenchloirde, dichlormethane, or ethene. Recently, a new type of catalysts was developed at TUM (Lst. für Anorganische Chemie), that allows the production of highly reactive polyisobutene at ambient temperature and in solvents free from chlorine. The tasks of this group are to transfer this method developed on the laboratory scale to the scale of a production reactor, the detection of the underlying chemical reaction mechanisms, and, finally, the further improvement of the method. To reach these tasks, we will exploit synergies between chemistry and informatics by combining methods of experimental chemistry (reaction mechanisms, testing of other catalysts, heterogeneous catalysis, etc.) and scientific computing (examination and optimization of the cooling of the exothermic reactions, flow and transport processes).

Kurzbeschreibung
The recent development of commodity as well as high-performance computers shows that computationally and data intensive tasks can only benefit from the hardware's full potential, if both processor and architecture features are taken into account - from the early algorithmic design up to the final implementation. Evident examples are the limited memory access via a hierarchy of cache memory and the increasingly hybrid and hierarchical design of high-end systems, both complicated by the ongoing trend towards multi- and manycore CPUs, accelerators and other HPSoCs (High Performance Systems on a Chip). Against this background, this proposal focuses on hardware-aware programming in the context of several applications from Science and Engineering:

Modelling and Simulation of Micropumps

Brief description
In this project, a new type of micropumps will be examined in detail. The micropump consists of a three-dimensional array of idemtical pores with periodically but asymmetrically varying diameter, within which a suspension with particles to be sortet is pumped to and fro. The interplay of the flow field and of stochastical thermical forces results - according to the principles of Brownian Motors - in a directed movement of the suspended particles. AS the transport direction depends on the dynamically relevant details of the system, in particular for example of the particle size, this hydrodynamical micropump can be used for a continuous and parallel sorting of particles. The Brownian motion opf small particles in a time-dependend viscous flow field through a pore with varying diameter represents a challenging and complex hydrodynamical problem. As, however, an as accurate as possible understanding of the underlying physical processes is indispensable for an experimental realisation of the micropump, this problem shall be exhaustively examined within this project with the help of a combination of analytical and numerical methods. Special subjects are:

Brief description
Die ungebremste Steigerung der Rechen- und Speicherleistung von Arbeitsplatzrechnern sowie neue Konzepte der geometrischen Modellierung und der numerischen Berechnungsverfahren lassen erwarten, dass in weniger als 10 Jahren ein erheblicher Teil der computergestützten Planung im konstruktiven Ingenieurbau nicht mehr an dimensionsreduzierten Modellen, sondern an streng volumenorientierten Modellen durchgeführt werden kann. Dies wird weitreichende Folgen für den gesamten Planungsprozess und insbesondere für die Integration der verschiedenen Teilmodelle mit sich bringen. Hierfür werden in diesem Forschungsvorhaben Konzepte entwickelt und deren Leistungsfähigkeit demonstriert.

Brief description
Due to their structuredness in combination with highly local adaptive refinement possibilities, adaptive Cartesian grids offer a very big potential in the context of hardware and, in particular, memory efficient implementation of numerical flow solvers. This project examines the applicability of the corresponding methods for the direct numerical simulation of turbulent channel flows on high performance computers. A particular focus is on the isotropic adaptive refinement of boundary layers and the efficient parallelisation on high performance computing architectures.

Particle Transport in Drift Ratchet as an Application Example for High-Performance CFD and FSI

Brief description
By means of numerical simulations (CFD and FSI), this project contributes to a better understanding of the physical phenomena involved in particle separation methods based on drift ratchets. This will allow for the optimisation and tailoring of the system parameters for specific types of particles and transporting flows. The drift ratchet simulation scenario is computationally expensive, especially because of large simulation times with small time steps, multi-scale models, multi-physics phenomena, and the movement of particles in the complex geometry of the ratchets.

In this project, we focus on:

Furthermore, we intend to broaden the software package GridSFEA to support and ease the execution of these large and complex simulations in grid.

Brief description
In the last years a growing attention has been dedicated to many body quantum systems from the point of view of quantum information. Indeed, after the initial investigation of simple systems as single or two qubits, the needs of understanding the characteristics of a realistic quantum information device leads necessary to the study of many body quantum systems. These studies are also driven by the very fast development of experiments which in the last years reach the goal of coherent control of a few qubits (ion traps, charge qubits, etc...) with a roadmap for further scaling and improvement of coherent control and manipulation techniques. Also, new paradigm of performing quantum information tasks, such as quantum information transfer, quantum cloning and others, without direct control of the whole quantum system but using our knowledge of it has increased the need of tools to understand in details the behaviour of many body quantum system as we find them in nature. These new goals of the quantum information community lead to an unavoidable exchange of knowledge with other communities that already have the know-how and the insight to address such problems; for example the condensed matter, computational physics or quantum chaos communities. Applying known techniques and developing new ones from a quantum information perspective have already produced fast and unexpected developments in these fields. The comprehension of many body quantum systems ranging from few qubits to the thermodynamical limit is thus needed and welcome not only to develop useful quantum information devices, but it will lead us to a better understanding of the quantum world.
