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).

Brief description

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:

  • Simulation of fluid flow problems on dynamically adaptive discretisation grids using recursive structured grid generation approaches and space-filling curves for parallelisation and cache-oblivious implementation.
  • Compute- and memory-intensive Boundary Element calculations of electric field and potential distributions in the context of simulation and optimisation of High Voltage Apparatus design. (Group Prof. Bode).
  • Hardware-aware algorithms for image reconstruction in medical imaging. (Group Prof. Schwaiger)

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 parallelization on high performance computing architectures.

Brief description

Im Rahmen der Übungen zur Vorlesung Numerische und Stochastische Grundlagen der Informatik, die im WS03/04 erstmals angeboten wurde und für Informatiker und Softwaretechniker Pflichtveranstaltung im 3. Semester ist, haben die Teilnehmer Programmieraufgaben zu numerischen Fragestellungen zu bearbeiten und im bestehenden eClaus-System elektronisch einzureichen.

Die Korrektur dieser Programme soll durch eine automatische Vorkorrektur effizienter gestaltet werden, die Ergebnisse der Vorkorrektur sollen so aufbereitet werden, dass sie den Teilnehmern als Ergänzung zu den Kommentaren der Korrektoren zur Verfügung gestellt wird, um mit vertretbarem Aufwand ein aussagekräftigeres individuelles Feedback zu ermöglichen.

Bei einer Nutzung der Programmieraufgaben als Selbstlernmodule ist auch eine ausschließliche Verwendung der automatischen Vorkorrektur möglich, die den Studierenden konkrete Hinweise auf Fehler und Verbesserungsmöglichkeiten liefert.

Brief description

Das Ziel des Projektes bestand darin, multimediale englischsprachige Lehrinhalte auf der Basis der Vorlesungen der Projektpartner zu entwickeln und innerhalb unterschiedlicher Lernszenarien einzusetzen.

Um Austausch und Wiederverwendung zu gewährleisten, war ein modulares Konzept mit geeigneter Hierarchie erforderlich. Auf oberster Ebene steht jeweils ein multimedialer Kurs, welcher ein gesamtes Themengebiet abdeckt und sich aus mehreren Lehrmodulen zusammensetzt. Die Bandbreite der Lehrmodule reicht dabei von Basis-Lehrmaterialien, wie z. B. einzelnen Folien einer PowerPoint-Präsentation, Video-Clips und Screen-Movies, bis hin zu größeren, in sich abgeschlossenen Multimedia-Vorlesungen. Letztere setzen sich aus Lehrmodulen feinerer Granularität zusammen, wobei multimediale Darstellungsformen die Anschaulichkeit wissenschaftlicher Zusammenhänge verbessern.

Während bei den Multimedia-Vorlesungen die Erläuterung des Lehrstoffes durch Dozenten erfolgt, ermöglichen web-basierte Lernapplikationen ergänzend dazu eine selbstständige Erarbeitung des Lehrstoffes. Die für die Präsenzveranstaltungen erstellten Lehrmodule bilden dabei die Ausgangsbasis für die Realisierung dieser Lernapplikationen. Die Lehrmodule und Lernapplikationen kommen schließlich auch im Rahmen der beruflichen Weiterbildung zum Einsatz.

Brief description

Spontan auftretende Phasenzerfälle bestimmen viele Prozesse in Natur und Technik. Solche Zerfälle sind zum Beispiel der entscheidende Schritt bei der Herstellung nanoskaliger Partikel, sie sind auch für Vorgänge in der Atmosphäre verantwortlich, die unser Klima stark beeinflussen. Bei der Modellierung und Simulation solcher Prozesse ist die Bestimmung der Keimbildungsrate von zentraler Bedeutung. Die Kenntnisse hierüber sind bislang völlig unzureichend, insbesondere, wenn Mischungen mehrerer Stoffe betrachtet werden. Die direkte molekulare Simulation bietet die Möglichkeit, solche Keimbildungsraten vorauszuberechnen. Bislang ist dies aber aufgrund von Beschränkungen der Rechenleistung nur für den weniger interessanten Fall extrem hoher Übersättigungen (Keimbildungsraten) möglich. Der Einsatz von HPC eröffnet hier völlig neue Perspektiven. Als besonders attraktiv erscheinen dabei Simulationen auf massiv parallelen, skalierbaren Architekturen mit verteiltem Speicher, von Clustern bis hin zum Grid, für die geeignete Verteilungs- und Lastausgleichsstrategien zu entwickeln sind. Zum besseren Verständnis des Prozesses der Keimbildung sowie der Morphologie der Nanopartikel muss deren Entstehung visualisiert werden. Hierzu müssen eine Vielzahl von verteilt simulierten Partikeln und ihre Eigenschaften in einer Darstellung vereint und durch adaptive Clustering-Verfahren interaktiv Strukturen extrahiert werden. Schließlich müssen, auch zur Validierung, die Ergebnisse der molekularen Betrachtung an höhere Ebenen der Prozessmodellierung und -simulation angebunden werden. Hierfür ist eine Schnittstelle zur populationsdynamischen Beschreibung der Phänomene zu schaffen. Ziel des Projekts ist es letztlich, Methoden und Werkzeuge für die skalenübergreifende Modellierung, Hochleistungsrechner-basierte Simulation und Visualisierung der betrachteten, technisch bzw. in der Natur außerordentlich wichtigen Vorgänge bereitzustellen. Dazu ist ein eng aufeinander abgestimmtes Zusammenwirken von ingenieurwissenschaftlichen Gruppen und Gruppen aus der Informatik erforderlich, wie es im Projekt vorgesehen ist.

Brief description

Zum Wintersemester 2001/2002 wurde an der TUM das interdisziplinäre, englischsprachige Master-Programm Computational Science and Engineering (CSE) als Aufbaustudiengang für Natur- und Ingenieurwissenschaftler eingeführt. Als Besonderheit sieht die CSE-Studienordnung vor, dass einzelne Module des Studiengangs auch von Instituten anderer Hochschulen eingebracht werden können, u.a. als virtuelle Lehreinheit im Rahmen der Virtuellen Hochschule Bayern (vhb).

Das Angebot virtueller Lehreinheiten soll gewährleisten, dass teilnehmende Studenten von der CSE-Kompetenz in ganz Bayern profitieren können. Darüber hinaus soll ein hochschulübergreifendes zeitgemäßes Lehrangebot zum Thema High Performance Computing (HPC) und CSE aufgebaut werden, auf das auch andere Universitäten bei Einführung entsprechender Studiengänge oder Vertiefungsfächer zugreifen können.

Im Rahmen dieses Projekts sollen zunächst zwei ausgewählte Module zur virtuellen Vorlesung bzw. virtuellen Übung ausgebaut werden: das Modul "Introduction to Scientific Computing", sowie das Modul "Modelling and Simulation in Continuum Mechanics".

As part of HP Technology for Teaching grant, 34 TabletPCs and accompanying equipment have been donated to improve education in the field of simulation techniques at the Universität Stuttgart.

They were used in various courses in the faculties

  • Computer Science, Electical Engineering, and Information Technology (Institutes: IPVS, VIS)
  • Civil and Environmental Engineering (IWS, ISVS)
  • Aero- and Astronautics Engineering (IAG)
  • Mechanical Engineering (ITT)
  • Mathematics and Physics (IANS)

Additionally, they have been successfully used in summer schools:

  • Summer School Berlin 2004 Use Transport Data! (Sept. 6-10, 2004)
  • Summer School Simulation Technology, Constanta/Romania (Sept. 9-20, 2004)
  • Ferienakademie Sarntal/Italy (2004-2008)

Project Abstract & Goals: Simulation has turned out to be one of the key technologies in practically all fields of science and engineering. Today, a successful use of simulation methods typically requires an interdisciplinary approach and involves researchers from mathematics, informatics, and the respective field of application. Hence, the education of students in simulation technology has to reflect this transdisciplinary nature.

This project’s goal was to improve education in simulation technology by connecting courses in the related fields via a homogeneous learning and problem-solving environment by means of mobile technology.

Impacts on Student Learning: Central point in the courses that used the Tablet PCs was to create a homogeneous working environment for the participants with the same set software tools (for numerical computations, for visualization of the results, and for presentation tools) and accompanying documents.

For example, in the course teaching numerics and statistics in the computer science program, interactive exercises using Maple helped to bring “dead mathematics” alive and the classroom group that was selected for these experiment was visibly more committed than the other groups – where the use of the students’ laptops is always handicapped by the different system environments.

In seminars in the mathematics program, as another example, the students were teamed up in pairs to work out their presentation (usually involving MATLAB computations). Here, especially the possibility to combine their final report into a well structured common document was considered as a significant boost in the student’s motivation and is again greatly facilitated by the homogenous environment provided to the participants.

Between the terms, the equipment was heavily in use on summer schools, where we noticed an additional advantage of the homogeneous equipment as it facilitates the connection between summer school courses and courses from the regular program. This results in an advanced level of the presentations involving simulation software and a better flow of summer school’s results back to the home university.

Impacts on Teaching: While the design of interactive elements into a course is always a fairly big effort, we noticed that the set of Tablet PCs facilitated the process in two ways. First, we have to care about only one system which saves a lot of work (and annoyance for students and teachers in case of unforeseen technical problems). Second, and this turned out to be the main advantage of the Tablet PCs over conventional laptop computers, an interesting and unconventional system turns out to motivate students to help voluntarily in the design of the course materials, bringing in a lot of ideas of their own. We found that the equipment was very helpful to remove the “glass wall” in the classrooms between teaching staff and students.

Technology Integration: The Tablet PCs were used in several configurations tailored to the specific course – with Windows or Linux operating systems and a selection of software for scientific computing (especially Maple and MATLAB, but also department-specific special software). The different configurations were stored as images on a server at the IPVS, where a set of Tablet PCs with the required configuration could easily be prepared.

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

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 modeling, 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.

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

In this project, a new type of micropumps will be examined in detail. The micropump consists of a three-dimensional array of identical pores with periodically but asymmetrically varying diameter, within which a suspension with particles to be sorted is pumped to and fro. The interplay of the flow field and of stochastic 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 of small particles in a time-dependent 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 realization 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:

  • transport properties of particles in dependence on the parameters particle size, pumping amplitude and frequency, pore shape, etc.,
  • Interactions between particles via their volume and hydrodynamical effects,
  • efficiency of particle sorting.

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 optimization 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:

  • computation of CFD and FSI simulations on grid computing environments;
  • parameter study of drift ratchet scenarios;
  • simulation software tuning for different high-performance computing architectures available within DEISA.
